I have been recently building NFDB, a new relay DB. This post is meant as a short overview.

Regular relays have challenges

Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.

NFDB: A scalable database for large relays

NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.

Search

NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.

Personalization

NFDB allows significant personalization: - Customized algorithms: Be your own algorithm. - Spam filtering: Filter content to your WoT, and use advanced spam filters. - Topic mutes: Mute topics, not keywords. - Media filtering: With Nostr.build, you will be able to filter NSFW and other content - Low data mode: Block notes that use high amounts of cellular data. - and more

Other

NFDB has support for many other features such as: - NIP-42: Protect your privacy with private drafts and DMs - Microrelays: Easily deploy your own personal microrelay - Containers: Dedicated, fast storage for discoverability events such as relay lists

Calcite: A local microrelay database

Calcite is a lightweight, local version of NFDB that is meant for microrelays and caching, meant for thousands of personal microrelays.

Calcite HA is an additional layer that allows live migration and relay failover in under 30 seconds, providing higher availability compared to current relays with greater simplicity. Calcite HA is enabled in all Calcite deployments.

For zero-downtime, NFDB is recommended.

Noswhere SmartCache

Relays are fixed in one location, but users can be anywhere.

Noswhere SmartCache is a CDN for relays that dynamically caches data on edge servers closest to you, allowing: - Multiple regions around the world - Improved throughput and performance - Faster loading times

routerd

routerd is a custom load-balancer optimized for Nostr relays, integrated with SmartCache.

routerd is specifically integrated with NFDB and Calcite HA to provide fast failover and high performance.

Ending notes

NFDB is planned to be deployed to Nostr.land in the coming weeks.

A lot more is to come. 👀️️️️️️

@ fd0bcf8c:521f98c0

The vag' sits on the edge of the highway, broken, hungry. Overhead flies a transcontinental plane filled with highly paid executives. The upper class has taken to the air, the lower class to the roads: there is no longer any bond between them, they are two nations."—The Sovereign Individual

Fire

I was talking to a friend last night. Coffee in hand. Watching flames consume branches. Spring night on his porch.

He believed in America's happy ending. Debt would vanish. Inflation would cool. Manufacturing would return. Good guys win.

I nodded. I wanted to believe.

He leaned forward, toward the flame. I sat back, watching both fire and sky.

His military photos hung inside. Service medals displayed. Patriotism bone-deep.

The pendulum clock on his porch wall swung steadily. Tick. Tock. Measuring moments. Marking epochs.

History tells another story. Not tragic. Just true.

Our time has come. America cut off couldn't compete. Factories sit empty. Supply chains span oceans. Skills lack. Children lag behind. Rebuilding takes decades.

Truth hurts. Truth frees.

Cycles

History moves in waves. Every 500 years, power shifts. Systems fall. Systems rise.

500 BC - Greek coins changed everything. Markets flourished. Athens dominated.

1 AD - Rome ruled commerce. One currency. Endless roads. Bustling ports.

500 AD - Rome faded. Not overnight. Slowly. Trade withered. Cities emptied. Money debased. Roads crumbled. Local strongmen rose. Peasants sought protection. Feudalism emerged.

People still lived. Still worked. Horizons narrowed. Knowledge concentrated. Most barely survived. Rich adapted. Poor suffered.

Self-reliance determined survival. Those growing food endured. Those making essential goods continued. Those dependent on imperial systems suffered most.

1000 AD - Medieval revival began. Venice dominated seas. China printed money. Cathedrals rose. Universities formed.

1500 AD - Europeans sailed everywhere. Spanish silver flowed. Banks financed kingdoms. Companies colonized continents. Power moved west.

The pendulum swung. East to West. West to East. Civilizations rose. Civilizations fell.

2000 AD - Pattern repeats. America strains. Digital networks expand. China rises. Debt swells. Old systems break.

We stand at the hinge.

Warnings

Signs everywhere. Dollar weakens globally. BRICS builds alternatives. Yuan buys oil. Factories rust. Debt exceeds GDP. Interest consumes budgets.

Bridges crumble. Education falters. Politicians chase votes. We consume. We borrow.

Rome fell gradually. Citizens barely noticed. Taxes increased. Currency devalued. Military weakened. Services decayed. Life hardened by degrees.

East Rome adapted. Survived centuries. West fragmented. Trade shrank. Some thrived. Others suffered. Life changed permanently.

Those who could feed themselves survived best. Those who needed the system suffered worst.

Pendulum

My friend poured another coffee. The burn pile popped loudly. Sparks flew upward like dying stars.

His face changed as facts accumulated. Military man. Trained to assess threats. Detect weaknesses.

He stared at the fire. National glory reduced to embers. Something shifted in his expression. Recognition.

His fingers tightened around his mug. Knuckles white. Eyes fixed on dying flames.

I traced the horizon instead. Observing landscape. Noting the contrast.

He touched the flag on his t-shirt. I adjusted my plain gray one.

The unpayable debt. The crumbling infrastructure. The forgotten manufacturing. The dependent supply chains. The devaluing currency.

The pendulum clock ticked. Relentless. Indifferent to empires.

His eyes said what his patriotism couldn't voice. Something fundamental breaking.

I'd seen this coming. Years traveling showed me. Different systems. Different values. American exceptionalism viewed from outside.

Pragmatism replaced my old idealism. See things as they are. Not as wished.

The logs shifted. Flames reached higher. Then lower. The cycle of fire.

Divergence

Society always splits during shifts.

Some adapt. Some don't.

Printing arrived. Scribes starved. Publishers thrived. Information accelerated. Readers multiplied. Ideas spread. Adapters prospered.

Steam engines came. Weavers died. Factory owners flourished. Villages emptied. Cities grew. Coal replaced farms. Railways replaced wagons. New skills meant survival.

Computers transformed everything. Typewriters vanished. Software boomed. Data replaced paper. Networks replaced cabinets. Programmers replaced typists. Digital skills determined success.

The self-reliant thrived in each transition. Those waiting for rescue fell behind.

Now AI reshapes creativity. Some artists resist. Some harness it. Gap widens daily.

Bitcoin offers refuge. Critics mock. Adopters build wealth. The distance grows.

Remote work redraws maps. Office-bound struggle. Location-free flourish.

The pendulum swings. Power shifts. Some rise with it. Some fall against it.

Two societies emerge. Adaptive. Resistant. Prepared. Pretending.

Advantage

Early adapters win. Not through genius. Through action.

First printers built empires. First factories created dynasties. First websites became giants.

Bitcoin followed this pattern. Laptop miners became millionaires. Early buyers became legends.

Critics repeat themselves: "Too volatile." "No value." "Government ban coming."

Doubters doubt. Builders build. Gap widens.

Self-reliance accelerates adaptation. No permission needed. No consensus required. Act. Learn. Build.

The burn pile flames like empire's glory. Bright. Consuming. Temporary.

Blindness

Our brains see tigers. Not economic shifts.

We panic at headlines. We ignore decades-long trends.

We notice market drops. We miss debt cycles.

We debate tweets. We ignore revolutions.

Not weakness. Just humanity. Foresight requires work. Study. Thought.

Self-reliant thinking means seeing clearly. No comforting lies. No pleasing narratives. Just reality.

The clock pendulum swings. Time passes regardless of observation.

Action

Empires fall. Families need security. Children need futures. Lives need meaning.

You can adapt faster than nations.

Assess honestly. What skills matter now? What preserves wealth? Who helps when needed?

Never stop learning. Factory workers learned code. Taxi drivers joined apps. Photographers went digital.

Diversify globally. No country owns tomorrow. Learn languages. Make connections. Stay mobile.

Protect your money. Dying empires debase currencies. Romans kept gold. Bitcoin offers similar shelter.

Build resilience. Grow food. Make energy. Stay strong. Keep friends. Read old books. Some things never change.

Self-reliance matters most. Can you feed yourself? Can you fix things? Can you solve problems? Can you create value without systems?

Movement

Humans were nomads first. Settlers second. Movement in our blood.

Our ancestors followed herds. Sought better lands. Survival meant mobility.

The pendulum swings here too. Nomad to farmer. City-dweller to digital nomad.

Rome fixed people to land. Feudalism bound serfs to soil. Nations created borders. Companies demanded presence.

Now technology breaks chains. Work happens anywhere. Knowledge flows everywhere.

The rebuild America seeks requires fixed positions. Factory workers. Taxpaying citizens in permanent homes.

But technology enables escape. Remote work. Digital currencies. Borderless businesses.

The self-reliant understand mobility as freedom. One location means one set of rules. One economy. One fate.

Many locations mean options. Taxes become predatory? Leave. Opportunities disappear? Find new ones.

Patriotism celebrates roots. Wisdom remembers wings.

My friend's boots dug into his soil. Planted. Territorial. Defending.

My Chucks rested lightly. Ready. Adaptable. Departing.

His toolshed held equipment to maintain boundaries. Fences. Hedges. Property lines.

My backpack contained tools for crossing them. Chargers. Adapters. Currency.

The burn pile flame flickers. Fixed in place. The spark flies free. Movement its nature.

During Rome's decline, the mobile survived best. Merchants crossing borders. Scholars seeking patrons. Those tied to crumbling systems suffered most.

Location independence means personal resilience. Economic downturns become geographic choices. Political oppression becomes optional suffering.

Technology shrinks distance. Digital work. Video relationships. Online learning.

Self-sovereignty requires mobility. The option to walk away. The freedom to arrive elsewhere.

Two more worlds diverge. The rooted. The mobile. The fixed. The fluid. The loyal. The free.

Hope

Not decline. Transition. Painful but temporary.

America may weaken. Humanity advances. Technology multiplies possibilities. Poverty falls. Knowledge grows.

Falling empires see doom. Rising ones see opportunity. Both miss half the picture.

Every shift brings destruction and creation. Rome fell. Europe struggled. Farms produced less. Cities shrank. Trade broke down.

Yet innovation continued. Water mills appeared. New plows emerged. Monks preserved books. New systems evolved.

Different doesn't mean worse for everyone.

Some industries die. Others birth. Some regions fade. Others bloom. Some skills become useless. Others become gold.

The self-reliant thrive in any world. They adapt. They build. They serve. They create.

Choose your role. Nostalgia or building.

The pendulum swings. East rises again. The cycle continues.

Fading

The burn pile dimmed. Embers fading. Night air cooling.

My friend's shoulders changed. Tension releasing. Something accepted.

His patriotism remained. His illusions departed.

The pendulum clock ticked steadily. Measuring more than minutes. Measuring eras.

Two coffee cups. His: military-themed, old and chipped but cherished. Mine: plain porcelain, new and unmarked.

His eyes remained on smoldering embers. Mine moved between him and the darkening trees.

His calendar marked local town meetings. Mine tracked travel dates.

The last flame flickered out. Spring peepers filled the silence.

In darkness, we watched smoke rise. The world changing. New choices ahead.

No empire lasts forever. No comfort in denial. Only clarity in acceptance.

Self-reliance the ancient answer. Build your skills. Secure your resources. Strengthen your body. Feed your mind. Help your neighbors.

The burn pile turned to ash. Empire's glory extinguished.

He stood facing his land. I faced the road.

A nod between us. Respect across division. Different strategies for the same storm.

He turned toward his home. I toward my vehicle.

The pendulum continued swinging. Power flowing east once more. Five centuries ending. Five centuries beginning.

"Bear in mind that everything that exists is already fraying at the edges." — Marcus Aurelius

Tomorrow depends not on nations. On us.

Poetry, unstacked

Painting by Early Fern, shared by Marine Eyes

It is difficult to get the news from poems yet men die miserably every day for lack of what is found there.—William Carlos Williams

April, the month Eliot famously deemed the cruelest, is kindest to poetry. It’s when we nationally awaken to poetry’s efforts to capture the human experience in all its messy contradictions, leaning into uncertainty and wonder and bringing readers along for the ride.

Williams’s adage pairs beautifully with Ezra Pound’s assertion that “Poetry is news that stays news.” Poetry* gives readers the most immediate and urgent hotline to feeling. Big emotions turn us instinctively, like human sunflowers, toward poems, which are singularly compact vehicles for thinking and feeling. They have a knack for distilling our existential questions and putting all that wondering to music—after all, the term lyric poetry comes from the lyre,* which accompanied the recitation of poetry in antiquity.

On Substack, poets shed the constraints of traditional publishing timelines, sharing works in progress and experimenting in real time. What arises isn’t just a collection of newsletters but a living anthology of established voices and emerging talents in conversation with one another and their readers. If you’re still not convinced that poetry is for you (it is!), I created a primer of Poems for Those Who Don’t “Get” Poetry. But beyond that gateway, Substack presents countless paths to discover the poems that will speak directly to you—from translation projects that breathe new life into ancient verse to craft discussions that demystify the process. Allow me to introduce you to a few of my favorites.

Poetry in progress

Quiddity: a word I love. It means “the inherent nature or essence of someone or something.” The you-ness of you. That is what the best poets translate through their writing—formal or free verse, ruminative or praising, expansive or brief. It’s the way one listens to the singular voice channeled through them** and delivers that voice alive on the page.

This is the foundation for the widest category of poetry on Substack. No two posts are alike: you might get the intimacy of seeing work that could later make its way into books, hearing poets muse about their writing lives, or watching notes and fragments coalesce into longer lyric explorations.

is one of the best-known poets on Substack, offering devoted readers a mix of never-before-seen work and poems from past collections. And his commitment to Substack’s potential as a propagator of new writing is especially inspiring to emerging writers.

Being witness to commitment and experimentation, that magical balance between discipline and freedom to explore, is riveting. I so admire , translator and former Random House editor ’s long-standing project to chronicle daily life:

Andrea Gibson’s gorgeously smart features videos of the poet reciting their work and contemplating illness, resilience, and the role that poetry plays in capturing duress, heartbreak, and hope. Here they are reading their poem “What Love Is”:

Keep watching

I was thrilled to see former U.S. Poet Laureate Tracy K. Smith join Substack recently. She’s already sharing poems, works in progress, and essays. Hear her reading a new poem, “I Don’t Believe in Doom,” here:

Keep listening

Then there’s , an ambitious translation project by , a writer dedicated to bringing these ancient poems from the Tang Dynasty (618-907) to a contemporary audience. Hyun Woo translates one poem from the collection every week. Here’s one of my favorites, number 55:

The Farewell to Those Who Will Stay at a Tavern of JinlingThe wind blows the willow flowers, filling the inn with fragrance;The ladies of Wu press the liquor, calling to the guests to try.The young men of Jinling come and see each other off;Those who will go, those who will not, each empty his goblet.I invite you to ask the water flowing east, to test it:Which is short and which is long, the thoughts of farewell or itself?

Curators and craft

The poet-as-curator offers us an assortment of poems organized by their own idiosyncratic logic. It’s like receiving the perfect mixtape: songs you’ve known and loved for years, and others you’re grateful to discover for the first time. Chances are good that within any given roundup, at least one poem will speak to you, introducing you to a new voice.

’s is one of my go-tos. He has a phenomenal reader’s eye for juxtapositions that span ages, styles, and modes, creating unexpected—and delightful—tensions and correspondences. His thematic roundups extend far beyond expected subjects like love and death to more nuanced territories like therapy (“This is progress”) and mood (“Puff out the hot-air balloon now”). Through Sean, I was reminded to revisit one of my favorite Audre Lorde poems:

Shared in “This is progress” by Sean Singer

In my own newsletter, , I do something similar: curating Poems for Your Weekend around themes that serve as a prescription for your mind or soul, while exploring how neuroscience and mindset can help us live more sustainable and enriching artistic lives. Through it all, I write about the role of wonder in poetry, the subject of my PhD.

For subtle close readings of poems through the lens of life rather than the ivory tower, I turn to ’s , with its deeply thoughtful essays on the poems he selects each week. His recent post on the poems of Linda Pastan includes this gorgeous poem from Insomnia:

Imaginary ConversationText within this block will maintain its original spacing when publishedYou tell me to live each day as if it were my last. This is in the kitchen where before coffee I complain of the day ahead—that obstacle race of minutes and hours, grocery stores and doctors.

But why the last? I ask. Why not live each day as if it were the first— all raw astonishment, Eve rubbing her eyes awake that first morning, the sun coming up like an ingénue in the east?

You grind the coffee with the small roar of a mind trying to clear itself. I set the table, glance out the window where dew has baptized every living surface.

Keep reading

I love Devin’s remarks: “why the last is the kind of question I adore, a question that does not assume it knows what we are supposedly supposed to know, a question that mirthfully pushes back against the world, and wonders aloud about astonishment in the face of certainty.”

For those interested in craft, literary powerhouse recently joined Substack and is already offering excellent writing exercises, as helpful for readers hoping to understand poetry as for poets creating their own. His Exercise 036: Begin with the End introduced even this poetry veteran to a new term: anadiplosis! is a resource-rich space, featuring interviews, classes, craft essays, and more. A large group of poets and readers has gathered to take advantage, creating a vibrant community. And a special shoutout in this section to , a poet whose candid essays on navigating both the publishing and dating world as a woman are their own kind of education on living more bravely and authentically.

Final thoughts

Whether encountered in an anthology or a newsletter, poems remind us of what Williams knew: that vital truths exist within their lines that we can find nowhere else. And there’s a special joy in reading them on Substack, where poets find renewed pleasure in publishing on their own terms, and where readers can witness the process and join the discussion. The digital format extends poetry’s reach, bringing these voices to new audiences who might not normally encounter them. Here, poets and readers are participating in poetry’s oldest tradition: the passing of essential truths from one human heart to another. I hope you’ll join us. https://connect-test.layer3.press/articles/4e5d2cee-8bd4-4fb0-9331-48bbeded3a47

@ 61bf790b:fe18b062

In a vast digital realm, two cities stood side by side: the towering, flashing metropolis of Feedia, and the decentralized, quiet city of Nostra.

Feedia was loud—blinding, buzzing, and always on. Screens plastered every wall, whispering the latest trends into citizens’ ears. But in this city, what you saw wasn’t up to you. It was determined by a towering, unseen force known as The Algorithm. It didn’t care what was true, meaningful, or helpful—only what would keep your eyes glued and your attention sold.

In Feedia, discovery wasn’t earned. It was assigned.

And worse—there was a caste system. To have a voice, you needed a Blue Check—a glowing badge that marked you as “worthy.” To get one, you had to pay or play. Pay monthly dues to the high towers or entertain The Algorithm enough to be deemed “valuable.” If you refused or couldn’t afford it, your voice was cast into the noise—buried beneath outrage bait and celebrity screams.

The unmarked were like ghosts—speaking into the void while the checked dined in Algorithm-favored towers. It was a digital monarchy dressed up as a democracy.

Then, there was Nostra.

There were no glowing checkmarks in Nostra—just signal. Every citizen had a light they carried, one that grew brighter the more they contributed: thoughtful posts, reshared ideas, built tools, or boosted others. Discovery was based not on payment or privilege, but participation and value.

In Nostra, you didn’t rise because you paid the gatekeeper—you rose because others lifted you. You weren’t spoon-fed; you sought, you found, you earned attention. It was harder, yes. But it was real.

And slowly, some in Feedia began to awaken. They grew tired of being fed fast-food content and ignored despite their voices. They looked across the river to Nostra, where minds weren’t bought—they were built.

And one by one, they began to cross.

Prelude

I wrote this post differently than any of my others. It started with a discussion with AI on an OPSec-inspired review of separation of powers, and evolved into quite an exciting debate! I asked Grok to write up a summary in my overall writing style, which it got pretty well. I've decided to post it exactly as-is. Ultimately, I think there are two solid ideas driving my stance here:

1. Perfect is the enemy of the good
2. Failure is the crucible of success

Beyond that, just some hard-core belief in freedom, separation of powers, and operating from self-interest.

Intro

Alright, buckle up. I’ve been chewing on this idea for a while, and it’s time to spit it out. Let’s look at the U.S. government like I’d look at a codebase under a cybersecurity audit—OPSEC style, no fluff. Forget the endless debates about what politicians should do. That’s noise. I want to talk about what they can do, the raw powers baked into the system, and why we should stop pretending those powers are sacred. If there’s a hole, either patch it or exploit it. No half-measures. And yeah, I’m okay if the whole thing crashes a bit—failure’s a feature, not a bug.

The Filibuster: A Security Rule with No Teeth

You ever see a firewall rule that’s more theater than protection? That’s the Senate filibuster. Everyone acts like it’s this untouchable guardian of democracy, but here’s the deal: a simple majority can torch it any day. It’s not a law; it’s a Senate preference, like choosing tabs over spaces. When people call killing it the “nuclear option,” I roll my eyes. Nuclear? It’s a button labeled “press me.” If a party wants it gone, they’ll do it. So why the dance?

I say stop playing games. Get rid of the filibuster. If you’re one of those folks who thinks it’s the only thing saving us from tyranny, fine—push for a constitutional amendment to lock it in. That’s a real patch, not a Post-it note. Until then, it’s just a vulnerability begging to be exploited. Every time a party threatens to nuke it, they’re admitting it’s not essential. So let’s stop pretending and move on.

Supreme Court Packing: Because Nine’s Just a Number

Here’s another fun one: the Supreme Court. Nine justices, right? Sounds official. Except it’s not. The Constitution doesn’t say nine—it’s silent on the number. Congress could pass a law tomorrow to make it 15, 20, or 42 (hitchhiker’s reference, anyone?). Packing the court is always on the table, and both sides know it. It’s like a root exploit just sitting there, waiting for someone to log in.

So why not call the bluff? If you’re in power—say, Trump’s back in the game—say, “I’m packing the court unless we amend the Constitution to fix it at nine.” Force the issue. No more shadowboxing. And honestly? The court’s got way too much power anyway. It’s not supposed to be a super-legislature, but here we are, with justices’ ideologies driving the bus. That’s a bug, not a feature. If the court weren’t such a kingmaker, packing it wouldn’t even matter. Maybe we should be talking about clipping its wings instead of just its size.

The Executive Should Go Full Klingon

Let’s talk presidents. I’m not saying they should wear Klingon armor and start shouting “Qapla’!”—though, let’s be real, that’d be awesome. I’m saying the executive should use every scrap of power the Constitution hands them. Enforce the laws you agree with, sideline the ones you don’t. If Congress doesn’t like it, they’ve got tools: pass new laws, override vetoes, or—here’s the big one—cut the budget. That’s not chaos; that’s the system working as designed.

Right now, the real problem isn’t the president overreaching; it’s the bureaucracy. It’s like a daemon running in the background, eating CPU and ignoring the user. The president’s supposed to be the one steering, but the administrative state’s got its own agenda. Let the executive flex, push the limits, and force Congress to check it. Norms? Pfft. The Constitution’s the spec sheet—stick to it.

Let the System Crash

Here’s where I get a little spicy: I’m totally fine if the government grinds to a halt. Deadlock isn’t a disaster; it’s a feature. If the branches can’t agree, let the president veto, let Congress starve the budget, let enforcement stall. Don’t tell me about “essential services.” Nothing’s so critical it can’t take a breather. Shutdowns force everyone to the table—debate, compromise, or expose who’s dropping the ball. If the public loses trust? Good. They’ll vote out the clowns or live with the circus they elected.

Think of it like a server crash. Sometimes you need a hard reboot to clear the cruft. If voters keep picking the same bad admins, well, the country gets what it deserves. Failure’s the best teacher—way better than limping along on autopilot.

States Are the Real MVPs

If the feds fumble, states step up. Right now, states act like junior devs waiting for the lead engineer to sign off. Why? Federal money. It’s a leash, and it’s tight. Cut that cash, and states will remember they’re autonomous. Some will shine, others will tank—looking at you, California. And I’m okay with that. Let people flee to better-run states. No bailouts, no excuses. States are like competing startups: the good ones thrive, the bad ones pivot or die.

Could it get uneven? Sure. Some states might turn into sci-fi utopias while others look like a post-apocalyptic vidya game. That’s the point—competition sorts it out. Citizens can move, markets adjust, and failure’s a signal to fix your act.

Chaos Isn’t the Enemy

Yeah, this sounds messy. States ignoring federal law, external threats poking at our seams, maybe even a constitutional crisis. I’m not scared. The Supreme Court’s there to referee interstate fights, and Congress sets the rules for state-to-state play. But if it all falls apart? Still cool. States can sort it without a babysitter—it’ll be ugly, but freedom’s worth it. External enemies? They’ll either unify us or break us. If we can’t rally, we don’t deserve the win.

Centralizing power to avoid this is like rewriting your app in a single thread to prevent race conditions—sure, it’s simpler, but you’re begging for a deadlock. Decentralized chaos lets states experiment, lets people escape, lets markets breathe. States competing to cut regulations to attract businesses? That’s a race to the bottom for red tape, but a race to the top for innovation—workers might gripe, but they’ll push back, and the tension’s healthy. Bring it—let the cage match play out. The Constitution’s checks are enough if we stop coddling the system.

Why This Matters

I’m not pitching a utopia. I’m pitching a stress test. The U.S. isn’t a fragile porcelain doll; it’s a rugged piece of hardware built to take some hits. Let it fail a little—filibuster, court, feds, whatever. Patch the holes with amendments if you want, or lean into the grind. Either way, stop fearing the crash. It’s how we debug the republic.

So, what’s your take? Ready to let the system rumble, or got a better way to secure the code? Hit me up—I’m all ears.

On Black-Starting the United Kingdom

In the event of a total failure of the electric grid, the United Kingdom would face a task at once technical and Sisyphean: the so-called black start — the reawakening of the nation’s darkened arteries without any external supply of power. In idealized manuals, the task is rendered brisk and clean, requiring but a few days' labor. In the world in which we live, it would be slower, more uncertain, and at times perilously close to impossible.

Let us unfold the matter layer by layer.

I. The Nature of the Undertaking

A black start is not a mere throwing of switches, but a sequential ballet. Small generating stations — diesel engines, hydro plants, gas turbines — must first breathe life into cold transmission lines. Substations must be coaxed into readiness. Load must be picked up cautiously, lest imbalance bring the whole effort to naught. Islands of power are stitched together, synchronized with exquisite care.

Each step is fraught with fragility. An unseen misalignment, an unsignaled overload, and hours of labor are lost.

II. The Dream of the Engineers

In theory, according to the National Grid Electricity System Operator (ESO), the sequence would unfold thus: within half a day, core transmission lines humming; within a day or two, hospitals lit and water flowing; within three days, cities reawakened; within a week, the nation, broadly speaking, restored to life.

This vision presupposes a fantasy of readiness: that black-start units are operational and plentiful; that communications systems, so delicately dependent on mobile networks and the internet, endure; that personnel, trained and coordinated, are on hand in sufficient numbers; and that no sabotage, no accident, no caprice of nature interrupts the dance.

III. The Real Order of Things

Reality is more obstinate. Many black-start capable plants have been shuttered in the name of efficiency. The financial incentives once offered to private generators for black-start readiness were judged insufficient; the providers withdrew.

Grid operations now rely on a lattice of private interests, demanding slow and complicated coordination. Telecommunications are vulnerable in a deep blackout. The old hands, steeped in the tacit lore of manual restoration, have retired, their knowledge scattered to the four winds. Cyber vulnerabilities have multiplied, and the grid’s physical inertia — the very thing that grants a system grace under perturbation — has grown thin, leaving the UK exposed to sudden collapses should synchronization falter.

Under such conditions, the best of hopes might yield five to ten days of partial recovery. Weeks would be required to restore the former web of normalcy. In certain cases — in the face of physical damage to high-voltage transformers, whose replacements take months if not years — black-start might founder altogether.

IV. The Quiet Admissions of Officialdom

In its polite documents, the National Grid ESO speaks carefully: essential services might see restoration within three days, but full public service would require "up to a week or longer." If designated black-start units were to fail — a real risk, given recent audits showing many unready — the timelines would stretch indefinitely.

In plain speech: in a true national blackout, the nation’s restoration would be a gamble.

V. The Forking Paths Ahead

If all proceeds well, Britain might stumble into light within three days. If the adversities accumulate — cyberattack, internal sabotage, simple human miscalculation — the process would stretch into weeks, even months. In the gravest scenarios, the nation would reconstitute not as one great engine, but as isolated islands of power, each jury-rigged and vulnerable.

Meanwhile, the paradoxical truth is that small and simple systems — the grids of Jersey, Malta, and the like — would outpace their mightier cousins, not despite their modest scale but because of it.

VI. Conclusion

The British grid, in short, is a triumph of late modernity — and like all such triumphs, it carries within itself the seeds of its own fragility. It works magnificently until the day it does not. When that day comes, recovery will be neither swift nor sure, but a slow, halting reweaving of threads too easily frayed.

In Jericoacoara, Brazil, a beach town famed for its natural beauty and vibrant tourism, an innovative project is quietly reshaping how locals and visitors think about money. Praia Bitcoin is an ambitious initiative to build a circular economy powered entirely by Bitcoin.

Launched in 2021 by entrepreneur Fernando Motolese, Praia Bitcoin was inspired by the Bitcoin Beach project in El Zonte, El Salvador. The vision is simple: create a self-sustaining Bitcoin economy where businesses and individuals use Bitcoin everyday in place of fiat money.

This idea holds special significance in Jericoacoara, where traditional banking services are scarce. The town lacks even basic infrastructure like ATMs, making financial inclusion a pressing need. With Praia Bitcoin, Bitcoin isn’t just a store of value—it’s a tool to empower a community and connect it to the global economy.

Transforming Jericoacoara with Bitcoin

Since its inception, Praia Bitcoin has worked to foster Bitcoin adoption in the area. Starting with a modest donation of 0.02 BTC, Fernando and his team have built a thriving ecosystem:

• Over 40 businesses now accept Bitcoin, ranging from souvenir shops and tour operators to beach vendors.
• Local students have received Bitcoin-loaded tap-to-pay, Bolt Cards, to use in their daily lives.
• Creative initiatives like “Bitcoin Banana Day” or "Frutas por Sats" (fruits for sats) where children buy fruits for 10 satoshis at school, have brought global attention to the project.

Praia Bitcoin’s success isn’t just about the adoption numbers, it’s about the stories. Families use Bitcoin to shop, business owners save on transaction fees, and children are learning the value of sound money at an early age.

LNbits - The Technology Behind Praia Bitcoin

Creating an economy on Bitcoin’s Lightning Network requires more than enthusiasm, it needs robust tools that are easy to use and adaptable to local needs. That’s where LNbits comes in.

Fernando and the Praia Bitcoin team have used LNbits’ open-source software to solve practical challenges and scale the project. With its modular design, LNbits provides tools that allow Praia Bitcoin to:

• Set Up Wallets: Community members receive user-friendly wallets that connect seamlessly to the Lightning Network, enabling fast, low-cost transactions.
• Issue BoltCards: Using LNbits’ BoltCard extension, the team has distributed NFC-enabled cards, allowing tap-to-pay functionality that makes Bitcoin payments as simple as using a credit card.
• Enable Flexible Payments: The project utilizes LNbits’ Point of Sale TPoS extension that allows merchants to easily receive Lightning Network payments.

Breaking Records, Building Community

Fernando doesn’t just implement solutions, he pushes boundaries. One of his most remarkable achievements was an attempt to set a world record for the most Lightning Network payments in the shortest amount of time. Over the course of one afternoon, 100 children in Jericoacoara received payments of 21,000 satoshis each, demonstrating the scalability and speed of Lightning-powered transactions.

This wasn’t just a technical feat, it was a community moment. The event showed how Bitcoin could serve as a tool for engagement, education, and empowerment, all while highlighting the possibilities of using the Lightning Network for real-world applications.

A Collaborative Approach to Innovation

One of the unique strengths of LNbits is its ability to evolve based on community feedback. While Fernando Motolese and Praia Bitcoin operate independently, their insights have helped refine the LNbits platform.

For example, Fernando’s need for a PIN-less ATM functionality led the LNbits team to implement that feature in the TPoS extension, that had the functionality but required a security PIN. This kind of collaboration isn’t about formal partnerships. It’s about how an open-source ecosystem thrives when real-world needs drive innovation.

The feedback loop between users like Fernando and developers ensures LNbits remains practical and relevant—not just for Praia Bitcoin but for countless other projects worldwide.

The Ripple Effect of Praia Bitcoin

Praia Bitcoin is a case study in what’s possible when Bitcoin meets a strong vision. By leveraging Bitcoin, the Lightning Network and LNbits, the project has redefined financial access in Jericoacoara, proving that small communities can lead big innovations.

For LNbits, Praia Bitcoin showcases the value of adaptable, open-source solutions. Whether it’s creating wallets, enabling NFC payments, or refining tools for real-world use, LNbits provides the infrastructure that makes projects like Praia Bitcoin possible.

But beyond the technical achievements, Praia Bitcoin reminds us of the human impact of Bitcoin adoption. It’s about children buying their first bananas with satoshis, families running businesses with lower fees, and a community connecting to a global financial network for the first time.

Conclusion

Praia Bitcoin’s journey is only getting started and its success is inspiring similar initiatives worldwide. For LNbits, being part of this story, is a testament to the power of the software and of open-source collaboration.

If you’re ready to build the future of Bitcoin adoption, LNbits offers the tools to turn ideas into impact.

A professional financial advisor can guide you to achieve long-term financial stability. They can assist you to define your goals to formulate strategic planning coupled with rational decision-making. Since the options are varied and multiple, how can you go about choosing a fiduciary financial advisor whose approach matches their financial goals? This guide explains exactly how to pick a financial advisor who suits your individual financial targets.

Defining Your Financial Needs and Goals

You need to specify your financial aspirations as well as your essential requirements so an advisor can create a suitable plan for your portfolio. Starters should establish their monetary targets before initiating contact with financial consultants. Any objective requires planning such as retirement preparation and investment management and education savings along with wealth protection and growth needs to be identified. Knowing your financial goals helps you determine if an advisor’s experience matches the needs of reaching your targets. Before you conduct meetings with possible financial advisors you need to have clearly established financial goals which will make these meetings goal-focused and beneficial.

Trusted financial advisors at Passive Capital Management can help you check out financial plan tailored to your needs and goals.

Look For Professional Credentials and Qualifications

Review carefully the advisor’s qualifications after you establish your goals. The strict training and ethical assessments that CFP Certified Financial Planner and the CFA Chartered Financial Analyst professionals demonstrate their professionalism. The designations set by these organizations prove advisors maintain knowledge in planning, investments and regulatory requirements. It is essential to verify that the advisor operates under fiduciary standards since this legal requirement ensures they must always act according to your benefit. It is essential to verify if an advisor functions as a fiduciary all the time because some only act under specified circumstances. Get a direct and unambiguous statement about their status. Under fiduciary relationships your financial security stands as the main priority of your financial advisor while fiduciary arrangements reduce potential conflicts between your interests.

Understand the Advisor’s Investment Approach

While consulting an advisor, you might encounter several hidden conflicts of interest. So a robust advisor-client connection based on their mutual investment approach including strategy selection is essential. Review the risk approaches of your advisor through inquiries to learn about their portfolio design strategies and market investment strategies. Technical competence must be combined with an awareness of your risk tolerance and time preferences according to their responses. A reliable advisor will adapt their investment methods to match the risk tolerance of their client combined with their financial destination.

Review their Service Package and Communication Style

A competent financial advisor functions past standard investment management duties. Their service range needs to include full-scale financial planning in areas such as retirement income strategies along with tax and estate planning solutions and insurance assessments. Check that their service suite matches your financial development needs. The advisor needs to maintain both clear and predictable ways of communication. Reveal their review process schedule and disclosure methods for reporting metrics as well as their availability to respond to questions at any time during the year. Professional communication builds reliable relationships that involve active participant commitment in planning activities.

Clarify the Fee Structure

Knowing how your advisor gets paid gives you the essential knowledge needed for building trust between you both. Financial advisors conduct business through payment structures which include flat fees, percentage-based fees on managed assets and extra earnings from their advisory products. The different compensation models bring their own effects and outcomes to the process. The most significant aspect for you is receiving clear explanations about fees while they are in alignment with your financial planning. The first practice of transparent communication by an advisor suggests they will uphold that approach during your entire time together.

Conclusion

Alongside numerical expertise your ideal advisor should function as a trustworthy partner because they will dedicate themselves to your financial growth. Strategic decision-making depends on the establishment of clear objectives and verification of expertise as well as confirmation of fiduciary principles and comprehensive evaluation of communication methods and associated fees. Your financial destiny requires organized assessment along with expert consulting while the correct professional consultant enables you to move through every phase of your path with obvious direction and solid self-assurance.

Opções importantes de montagem Btrfs

Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.

As opções de montagem Btrfs mais importantes são:

**1. acl e noacl

**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.

A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .

Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.

**2. autodefrag e noautodefrag

**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.

A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.

A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.

Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.

**3. compactar e compactar-forçar

**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.

A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).

A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.

O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.

Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).

Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:

• compress=algoritmo:nível
• compress-force=algoritmo:nível

Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .

**4. subvol e subvolid

**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.

A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.

A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.

Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .

**5. dispositivo

A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.

Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.

Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.

Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.

Por exemplo,

• dispositivo=/dev/sdb
• dispositivo=/dev/sdb,dispositivo=/dev/sdc
• dispositivo=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d
• device=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d,device=UUID_SUB=f7ce4875-0874-436a-b47d-3edef66d3424

**6. degraded

A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.

Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.

**7. commit

A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.

O padrão é definido como 30 segundos.

Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).

**8. ssd e nossd

A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.

A opção de montagem nossd desativa a otimização do SSD.

O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.

**9. ssd_spread e nossd_spread

A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).

A opção de montagem nossd_spread desativa o recurso ssd_spread .

O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.

**10. descarte e nodiscard

Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.

Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.

Por padrão, a opção de montagem nodiscard é usada.

**11. norecovery

Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.

**12. usebackuproot e nousebackuproot

Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.

A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.

**13. space_cache, space_cache=version, nospace_cache e clear_cache

A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).

O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2

O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).

Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.

A opção de montagem clear_cache é usada para limpar o cache de espaço livre.

Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .

Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1

A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.

Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache

**14. skip_balance

Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**

**15. datacow e nodatacow

A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.

Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .

**16. datasum e nodatasum

A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.

Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .

Perfis Btrfs

Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.

Os perfis Btrfs disponíveis são os seguintes:

single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.

dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.

raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .

raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .

raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .

raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .

raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .

O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .

Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .

raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.

Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.

Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .

raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.

Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.

Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

@ c066aac5:6a41a034

I’m drawn to extremities in art. The louder, the bolder, the more outrageous, the better. Bold art takes me out of the mundane into a whole new world where anything and everything is possible. Having grown up in the safety of the suburban midwest, I was a bit of a rebellious soul in search of the satiation that only came from the consumption of the outrageous. My inclination to find bold art draws me to NOSTR, because I believe NOSTR can be the place where the next generation of artistic pioneers go to express themselves. I also believe that as much as we are able, were should invite them to come create here.

My Background: A Small Side Story

My father was a professional gamer in the 80s, back when there was no money or glory in the avocation. He did get a bit of spotlight though after the fact: in the mid 2000’s there were a few parties making documentaries about that era of gaming as well as current arcade events (namely 2007’sChasing GhostsandThe King of Kong: A Fistful of Quarters). As a result of these documentaries, there was a revival in the arcade gaming scene. My family attended events related to the documentaries or arcade gaming and I became exposed to a lot of things I wouldn’t have been able to find. The producer ofThe King of Kong: A Fistful of Quarters had previously made a documentary calledNew York Dollwhich was centered around the life of bassist Arthur Kane. My 12 year old mind was blown: The New York Dolls were a glam-punk sensation dressed in drag. The music was from another planet. Johnny Thunders’ guitar playing was like Chuck Berry with more distortion and less filter. Later on I got to meet the Galaga record holder at the time, Phil Day, in Ottumwa Iowa. Phil is an Australian man of high intellect and good taste. He exposed me to great creators such as Nick Cave & The Bad Seeds, Shakespeare, Lou Reed, artists who created things that I had previously found inconceivable.

I believe this time period informed my current tastes and interests, but regrettably I think it also put coals on the fire of rebellion within. I stopped taking my parents and siblings seriously, the Christian faith of my family (which I now hold dearly to) seemed like a mundane sham, and I felt I couldn’t fit in with most people because of my avant-garde tastes. So I write this with the caveat that there should be a way to encourage these tastes in children without letting them walk down the wrong path. There is nothing inherently wrong with bold art, but I’d advise parents to carefully find ways to cultivate their children’s tastes without completely shutting them down and pushing them away as a result. My parents were very loving and patient during this time; I thank God for that.

With that out of the way, lets dive in to some bold artists:

Nicolas Cage: Actor

There is an excellent video by Wisecrack on Nicolas Cage that explains him better than I will, which I will linkhere. Nicolas Cage rejects the idea that good acting is tied to mere realism; all of his larger than life acting decisions are deliberate choices. When that clicked for me, I immediately realized the man is a genius. He borrows from Kabuki and German Expressionism, art forms that rely on exaggeration to get the message across. He has even created his own acting style, which he calls Nouveau Shamanic. He augments his imagination to go from acting to being. Rather than using the old hat of method acting, he transports himself to a new world mentally. The projects he chooses to partake in are based on his own interests or what he considers would be a challenge (making a bad script good for example). Thus it doesn’t matter how the end result comes out; he has already achieved his goal as an artist. Because of this and because certain directors don’t know how to use his talents, he has a noticeable amount of duds in his filmography. Dig around the duds, you’ll find some pure gold. I’d personally recommend the filmsPig, Joe, Renfield, and his Christmas film The Family Man.

Nick Cave: Songwriter

What a wild career this man has had! From the apocalyptic mayhem of his band The Birthday Party to the pensive atmosphere of his albumGhosteen, it seems like Nick Cave has tried everything. I think his secret sauce is that he’s always working. He maintains an excellent newsletter calledThe Red Hand Files, he has written screenplays such asLawless, he has written books, he has made great film scores such asThe Assassination of Jesse James by the Coward Robert Ford, the man is religiously prolific. I believe that one of the reasons he is prolific is that he’s not afraid to experiment. If he has an idea, he follows it through to completion. From the albumMurder Ballads(which is comprised of what the title suggests) to his rejected sequel toGladiator(Gladiator: Christ Killer), he doesn’t seem to be afraid to take anything on. This has led to some over the top works as well as some deeply personal works. Albums likeSkeleton TreeandGhosteenwere journeys through the grief of his son’s death. The Boatman’s Callis arguably a better break-up album than anything Taylor Swift has put out. He’s not afraid to be outrageous, he’s not afraid to offend, but most importantly he’s not afraid to be himself. Works I’d recommend include The Birthday Party’sLive 1981-82, Nick Cave & The Bad Seeds’The Boatman’s Call, and the filmLawless.

Jim Jarmusch: Director

I consider Jim’s films to be bold almost in an ironic sense: his works are bold in that they are, for the most part, anti-sensational. He has a rule that if his screenplays are criticized for a lack of action, he makes them even less eventful. Even with sensational settings his films feel very close to reality, and they demonstrate the beauty of everyday life. That's what is bold about his art to me: making the sensational grounded in reality while making everyday reality all the more special. Ghost Dog: The Way of the Samurai is about a modern-day African-American hitman who strictly follows the rules of the ancient Samurai, yet one can resonate with the humanity of a seemingly absurd character. Only Lovers Left Aliveis a vampire love story, but in the middle of a vampire romance one can see their their own relationships in a new deeply human light. Jim’s work reminds me that art reflects life, and that there is sacred beauty in seemingly mundane everyday life. I personally recommend his filmsPaterson,Down by Law, andCoffee and Cigarettes.

NOSTR: We Need Bold Art

NOSTR is in my opinion a path to a better future. In a world creeping slowly towards everything apps, I hope that the protocol where the individual owns their data wins over everything else. I love freedom and sovereignty. If NOSTR is going to win the race of everything apps, we need more than Bitcoin content. We need more than shirtless bros paying for bananas in foreign countries and exercising with girls who have seductive accents. Common people cannot see themselves in such a world. NOSTR needs to catch the attention of everyday people. I don’t believe that this can be accomplished merely by introducing more broadly relevant content; people are searching for content that speaks to them. I believe that NOSTR can and should attract artists of all kinds because NOSTR is one of the few places on the internet where artists can express themselves fearlessly. Getting zaps from NOSTR’s value-for-value ecosystem has far less friction than crowdfunding a creative project or pitching investors that will irreversibly modify an artist’s vision. Having a place where one can post their works without fear of censorship should be extremely enticing. Having a place where one can connect with fellow humans directly as opposed to a sea of bots should seem like the obvious solution. If NOSTR can become a safe haven for artists to express themselves and spread their work, I believe that everyday people will follow. The banker whose stressful job weighs on them will suddenly find joy with an original meme made by a great visual comedian. The programmer for a healthcare company who is drowning in hopeless mundanity could suddenly find a new lust for life by hearing the song of a musician who isn’t afraid to crowdfund their their next project by putting their lighting address on the streets of the internet. The excel guru who loves independent film may find that NOSTR is the best way to support non corporate movies. My closing statement: continue to encourage the artists in your life as I’m sure you have been, but while you’re at it give them the purple pill. You may very well be a part of building a better future.

Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.

That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.

As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.

Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.

Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.

The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.

When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.

Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

One of the most common criticisms leveled against nostr is the perceived lack of assurance when it comes to data storage. Critics argue that without a centralized authority guaranteeing that all data is preserved, important information will be lost. They also claim that running a relay will become prohibitively expensive. While there is truth to these concerns, they miss the mark. The genius of nostr lies in its flexibility, resilience, and the way it harnesses human incentives to ensure data availability in practice.

A nostr relay is simply a server that holds cryptographically verifiable signed data and makes it available to others. Relays are simple, flexible, open, and require no permission to run. Critics are right that operating a relay attempting to store all nostr data will be costly. What they miss is that most will not run all encompassing archive relays. Nostr does not rely on massive archive relays. Instead, anyone can run a relay and choose to store whatever subset of data they want. This keeps costs low and operations flexible, making relay operation accessible to all sorts of individuals and entities with varying use cases.

Critics are correct that there is no ironclad guarantee that every piece of data will always be available. Unlike bitcoin where data permanence is baked into the system at a steep cost, nostr does not promise that every random note or meme will be preserved forever. That said, in practice, any data perceived as valuable by someone will likely be stored and distributed by multiple entities. If something matters to someone, they will keep a signed copy.

Nostr is the Streisand Effect in protocol form. The Streisand effect is when an attempt to suppress information backfires, causing it to spread even further. With nostr, anyone can broadcast signed data, anyone can store it, and anyone can distribute it. Try to censor something important? Good luck. The moment it catches attention, it will be stored on relays across the globe, copied, and shared by those who find it worth keeping. Data deemed important will be replicated across servers by individuals acting in their own interest.

Nostr’s distributed nature ensures that the system does not rely on a single point of failure or a corporate overlord. Instead, it leans on the collective will of its users. The result is a network where costs stay manageable, participation is open to all, and valuable verifiable data is stored and distributed forever.

Is it actually called “summary”?

A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:

“I just feel like I’m so behind.”

Behind who? Behind what?

There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.

Where did this come from?

Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.

But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.

Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.

I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.

“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?

If you need a permission slip to stop comparing, let this be it.

You’re not late. You’re not early.
You’re right on time.

Warning: This piece contains a conversation about difficult topics. Please proceed with caution.

TL;DR please educate your children about online safety.

Julian Assange wrote in his 2012 book Cypherpunks, “This book is not a manifesto. There isn’t time for that. This book is a warning.” I read it a few times over the past summer. Those opening lines definitely stood out to me. I wish we had listened back then. He saw something about the internet that few had the ability to see. There are some individuals who are so close to a topic that when they speak, it’s difficult for others who aren’t steeped in it to visualize what they’re talking about. I didn’t read the book until more recently. If I had read it when it came out, it probably would have sounded like an unknown foreign language to me. Today it makes more sense.

This isn’t a manifesto. This isn’t a book. There is no time for that. It’s a warning and a possible solution from a desperate and determined survivor advocate who has been pulling and unraveling a thread for a few years. At times, I feel too close to this topic to make any sense trying to convey my pathway to my conclusions or thoughts to the general public. My hope is that if nothing else, I can convey my sense of urgency while writing this. This piece is a watchman’s warning.

When a child steps online, they are walking into a new world. A new reality. When you hand a child the internet, you are handing them possibilities—good, bad, and ugly. This is a conversation about lowering the potential of negative outcomes of stepping into that new world and how I came to these conclusions. I constantly compare the internet to the road. You wouldn’t let a young child run out into the road with no guidance or safety precautions. When you hand a child the internet without any type of guidance or safety measures, you are allowing them to play in rush hour, oncoming traffic. “Look left, look right for cars before crossing.” We almost all have been taught that as children. What are we taught as humans about safety before stepping into a completely different reality like the internet? Very little.

I could never really figure out why many folks in tech, privacy rights activists, and hackers seemed so cold to me while talking about online child sexual exploitation. I always figured that as a survivor advocate for those affected by these crimes, that specific, skilled group of individuals would be very welcoming and easy to talk to about such serious topics. I actually had one hacker laugh in my face when I brought it up while I was looking for answers. I thought maybe this individual thought I was accusing them of something I wasn’t, so I felt bad for asking. I was constantly extremely disappointed and would ask myself, “Why don’t they care? What could I say to make them care more? What could I say to make them understand the crisis and the level of suffering that happens as a result of the problem?”

I have been serving minor survivors of online child sexual exploitation for years. My first case serving a survivor of this specific crime was in 2018—a 13-year-old girl sexually exploited by a serial predator on Snapchat. That was my first glimpse into this side of the internet. I won a national award for serving the minor survivors of Twitter in 2023, but I had been working on that specific project for a few years. I was nominated by a lawyer representing two survivors in a legal battle against the platform. I’ve never really spoken about this before, but at the time it was a choice for me between fighting Snapchat or Twitter. I chose Twitter—or rather, Twitter chose me. I heard about the story of John Doe #1 and John Doe #2, and I was so unbelievably broken over it that I went to war for multiple years. I was and still am royally pissed about that case. As far as I was concerned, the John Doe #1 case proved that whatever was going on with corporate tech social media was so out of control that I didn’t have time to wait, so I got to work. It was reading the messages that John Doe #1 sent to Twitter begging them to remove his sexual exploitation that broke me. He was a child begging adults to do something. A passion for justice and protecting kids makes you do wild things. I was desperate to find answers about what happened and searched for solutions. In the end, the platform Twitter was purchased. During the acquisition, I just asked Mr. Musk nicely to prioritize the issue of detection and removal of child sexual exploitation without violating digital privacy rights or eroding end-to-end encryption. Elon thanked me multiple times during the acquisition, made some changes, and I was thanked by others on the survivors’ side as well.

I still feel that even with the progress made, I really just scratched the surface with Twitter, now X. I left that passion project when I did for a few reasons. I wanted to give new leadership time to tackle the issue. Elon Musk made big promises that I knew would take a while to fulfill, but mostly I had been watching global legislation transpire around the issue, and frankly, the governments are willing to go much further with X and the rest of corporate tech than I ever would. My work begging Twitter to make changes with easier reporting of content, detection, and removal of child sexual exploitation material—without violating privacy rights or eroding end-to-end encryption—and advocating for the minor survivors of the platform went as far as my principles would have allowed. I’m grateful for that experience. I was still left with a nagging question: “How did things get so bad with Twitter where the John Doe #1 and John Doe #2 case was able to happen in the first place?” I decided to keep looking for answers. I decided to keep pulling the thread.

I never worked for Twitter. This is often confusing for folks. I will say that despite being disappointed in the platform’s leadership at times, I loved Twitter. I saw and still see its value. I definitely love the survivors of the platform, but I also loved the platform. I was a champion of the platform’s ability to give folks from virtually around the globe an opportunity to speak and be heard.

I want to be clear that John Doe #1 really is my why. He is the inspiration. I am writing this because of him. He represents so many globally, and I’m still inspired by his bravery. One child’s voice begging adults to do something—I’m an adult, I heard him. I’d go to war a thousand more lifetimes for that young man, and I don’t even know his name. Fighting has been personally dark at times; I’m not even going to try to sugarcoat it, but it has been worth it.

The data surrounding the very real crime of online child sexual exploitation is available to the public online at any time for anyone to see. I’d encourage you to go look at the data for yourself. I believe in encouraging folks to check multiple sources so that you understand the full picture. If you are uncomfortable just searching around the internet for information about this topic, use the terms “CSAM,” “CSEM,” “SG-CSEM,” or “AI Generated CSAM.” The numbers don’t lie—it’s a nightmare that’s out of control. It’s a big business. The demand is high, and unfortunately, business is booming. Organizations collect the data, tech companies often post their data, governments report frequently, and the corporate press has covered a decent portion of the conversation, so I’m sure you can find a source that you trust.

Technology is changing rapidly, which is great for innovation as a whole but horrible for the crime of online child sexual exploitation. Those wishing to exploit the vulnerable seem to be adapting to each technological change with ease. The governments are so far behind with tackling these issues that as I’m typing this, it’s borderline irrelevant to even include them while speaking about the crime or potential solutions. Technology is changing too rapidly, and their old, broken systems can’t even dare to keep up. Think of it like the governments’ “War on Drugs.” Drugs won. In this case as well, the governments are not winning. The governments are talking about maybe having a meeting on potentially maybe having legislation around the crimes. The time to have that meeting would have been many years ago. I’m not advocating for governments to legislate our way out of this. I’m on the side of educating and innovating our way out of this.

I have been clear while advocating for the minor survivors of corporate tech platforms that I would not advocate for any solution to the crime that would violate digital privacy rights or erode end-to-end encryption. That has been a personal moral position that I was unwilling to budge on. This is an extremely unpopular and borderline nonexistent position in the anti-human trafficking movement and online child protection space. I’m often fearful that I’m wrong about this. I have always thought that a better pathway forward would have been to incentivize innovation for detection and removal of content. I had no previous exposure to privacy rights activists or Cypherpunks—actually, I came to that conclusion by listening to the voices of MENA region political dissidents and human rights activists. After developing relationships with human rights activists from around the globe, I realized how important privacy rights and encryption are for those who need it most globally. I was simply unwilling to give more power, control, and opportunities for mass surveillance to big abusers like governments wishing to enslave entire nations and untrustworthy corporate tech companies to potentially end some portion of abuses online. On top of all of it, it has been clear to me for years that all potential solutions outside of violating digital privacy rights to detect and remove child sexual exploitation online have not yet been explored aggressively. I’ve been disappointed that there hasn’t been more of a conversation around preventing the crime from happening in the first place.

What has been tried is mass surveillance. In China, they are currently under mass surveillance both online and offline, and their behaviors are attached to a social credit score. Unfortunately, even on state-run and controlled social media platforms, they still have child sexual exploitation and abuse imagery pop up along with other crimes and human rights violations. They also have a thriving black market online due to the oppression from the state. In other words, even an entire loss of freedom and privacy cannot end the sexual exploitation of children online. It’s been tried. There is no reason to repeat this method.

It took me an embarrassingly long time to figure out why I always felt a slight coldness from those in tech and privacy-minded individuals about the topic of child sexual exploitation online. I didn’t have any clue about the “Four Horsemen of the Infocalypse.” This is a term coined by Timothy C. May in 1988. I would have been a child myself when he first said it. I actually laughed at myself when I heard the phrase for the first time. I finally got it. The Cypherpunks weren’t wrong about that topic. They were so spot on that it is borderline uncomfortable. I was mad at first that they knew that early during the birth of the internet that this issue would arise and didn’t address it. Then I got over it because I realized that it wasn’t their job. Their job was—is—to write code. Their job wasn’t to be involved and loving parents or survivor advocates. Their job wasn’t to educate children on internet safety or raise awareness; their job was to write code.

They knew that child sexual abuse material would be shared on the internet. They said what would happen—not in a gleeful way, but a prediction. Then it happened.

I equate it now to a concrete company laying down a road. As you’re pouring the concrete, you can say to yourself, “A terrorist might travel down this road to go kill many, and on the flip side, a beautiful child can be born in an ambulance on this road.” Who or what travels down the road is not their responsibility—they are just supposed to lay the concrete. I’d never go to a concrete pourer and ask them to solve terrorism that travels down roads. Under the current system, law enforcement should stop terrorists before they even make it to the road. The solution to this specific problem is not to treat everyone on the road like a terrorist or to not build the road.

So I understand the perceived coldness from those in tech. Not only was it not their job, but bringing up the topic was seen as the equivalent of asking a free person if they wanted to discuss one of the four topics—child abusers, terrorists, drug dealers, intellectual property pirates, etc.—that would usher in digital authoritarianism for all who are online globally.

Privacy rights advocates and groups have put up a good fight. They stood by their principles. Unfortunately, when it comes to corporate tech, I believe that the issue of privacy is almost a complete lost cause at this point. It’s still worth pushing back, but ultimately, it is a losing battle—a ticking time bomb.

I do think that corporate tech providers could have slowed down the inevitable loss of privacy at the hands of the state by prioritizing the detection and removal of CSAM when they all started online. I believe it would have bought some time, fewer would have been traumatized by that specific crime, and I do believe that it could have slowed down the demand for content. If I think too much about that, I’ll go insane, so I try to push the “if maybes” aside, but never knowing if it could have been handled differently will forever haunt me. At night when it’s quiet, I wonder what I would have done differently if given the opportunity. I’ll probably never know how much corporate tech knew and ignored in the hopes that it would go away while the problem continued to get worse. They had different priorities. The most voiceless and vulnerable exploited on corporate tech never had much of a voice, so corporate tech providers didn’t receive very much pushback.

Now I’m about to say something really wild, and you can call me whatever you want to call me, but I’m going to say what I believe to be true. I believe that the governments are either so incompetent that they allowed the proliferation of CSAM online, or they knowingly allowed the problem to fester long enough to have an excuse to violate privacy rights and erode end-to-end encryption. The US government could have seized the corporate tech providers over CSAM, but I believe that they were so useful as a propaganda arm for the regimes that they allowed them to continue virtually unscathed.

That season is done now, and the governments are making the issue a priority. It will come at a high cost. Privacy on corporate tech providers is virtually done as I’m typing this. It feels like a death rattle. I’m not particularly sure that we had much digital privacy to begin with, but the illusion of a veil of privacy feels gone.

To make matters slightly more complex, it would be hard to convince me that once AI really gets going, digital privacy will exist at all.

I believe that there should be a conversation shift to preserving freedoms and human rights in a post-privacy society.

I don’t want to get locked up because AI predicted a nasty post online from me about the government. I’m not a doomer about AI—I’m just going to roll with it personally. I’m looking forward to the positive changes that will be brought forth by AI. I see it as inevitable. A bit of privacy was helpful while it lasted. Please keep fighting to preserve what is left of privacy either way because I could be wrong about all of this.

On the topic of AI, the addition of AI to the horrific crime of child sexual abuse material and child sexual exploitation in multiple ways so far has been devastating. It’s currently out of control. The genie is out of the bottle. I am hopeful that innovation will get us humans out of this, but I’m not sure how or how long it will take. We must be extremely cautious around AI legislation. It should not be illegal to innovate even if some bad comes with the good. I don’t trust that the governments are equipped to decide the best pathway forward for AI. Source: the entire history of the government.

I have been personally negatively impacted by AI-generated content. Every few days, I get another alert that I’m featured again in what’s called “deep fake pornography” without my consent. I’m not happy about it, but what pains me the most is the thought that for a period of time down the road, many globally will experience what myself and others are experiencing now by being digitally sexually abused in this way. If you have ever had your picture taken and posted online, you are also at risk of being exploited in this way. Your child’s image can be used as well, unfortunately, and this is just the beginning of this particular nightmare. It will move to more realistic interpretations of sexual behaviors as technology improves. I have no brave words of wisdom about how to deal with that emotionally. I do have hope that innovation will save the day around this specific issue. I’m nervous that everyone online will have to ID verify due to this issue. I see that as one possible outcome that could help to prevent one problem but inadvertently cause more problems, especially for those living under authoritarian regimes or anyone who needs to remain anonymous online. A zero-knowledge proof (ZKP) would probably be the best solution to these issues. There are some survivors of violence and/or sexual trauma who need to remain anonymous online for various reasons. There are survivor stories available online of those who have been abused in this way. I’d encourage you seek out and listen to their stories.

There have been periods of time recently where I hesitate to say anything at all because more than likely AI will cover most of my concerns about education, awareness, prevention, detection, and removal of child sexual exploitation online, etc.

Unfortunately, some of the most pressing issues we’ve seen online over the last few years come in the form of “sextortion.” Self-generated child sexual exploitation (SG-CSEM) numbers are continuing to be terrifying. I’d strongly encourage that you look into sextortion data. AI + sextortion is also a huge concern. The perpetrators are using the non-sexually explicit images of children and putting their likeness on AI-generated child sexual exploitation content and extorting money, more imagery, or both from minors online. It’s like a million nightmares wrapped into one. The wild part is that these issues will only get more pervasive because technology is harnessed to perpetuate horror at a scale unimaginable to a human mind.

Even if you banned phones and the internet or tried to prevent children from accessing the internet, it wouldn’t solve it. Child sexual exploitation will still be with us until as a society we start to prevent the crime before it happens. That is the only human way out right now.

There is no reset button on the internet, but if I could go back, I’d tell survivor advocates to heed the warnings of the early internet builders and to start education and awareness campaigns designed to prevent as much online child sexual exploitation as possible. The internet and technology moved quickly, and I don’t believe that society ever really caught up. We live in a world where a child can be groomed by a predator in their own home while sitting on a couch next to their parents watching TV. We weren’t ready as a species to tackle the fast-paced algorithms and dangers online. It happened too quickly for parents to catch up. How can you parent for the ever-changing digital world unless you are constantly aware of the dangers?

I don’t think that the internet is inherently bad. I believe that it can be a powerful tool for freedom and resistance. I’ve spoken a lot about the bad online, but there is beauty as well. We often discuss how victims and survivors are abused online; we rarely discuss the fact that countless survivors around the globe have been able to share their experiences, strength, hope, as well as provide resources to the vulnerable. I do question if giving any government or tech company access to censorship, surveillance, etc., online in the name of serving survivors might not actually impact a portion of survivors negatively. There are a fair amount of survivors with powerful abusers protected by governments and the corporate press. If a survivor cannot speak to the press about their abuse, the only place they can go is online, directly or indirectly through an independent journalist who also risks being censored. This scenario isn’t hard to imagine—it already happened in China. During #MeToo, a survivor in China wanted to post their story. The government censored the post, so the survivor put their story on the blockchain. I’m excited that the survivor was creative and brave, but it’s terrifying to think that we live in a world where that situation is a necessity.

I believe that the future for many survivors sharing their stories globally will be on completely censorship-resistant and decentralized protocols. This thought in particular gives me hope. When we listen to the experiences of a diverse group of survivors, we can start to understand potential solutions to preventing the crimes from happening in the first place.

My heart is broken over the gut-wrenching stories of survivors sexually exploited online. Every time I hear the story of a survivor, I do think to myself quietly, “What could have prevented this from happening in the first place?” My heart is with survivors.

My head, on the other hand, is full of the understanding that the internet should remain free. The free flow of information should not be stopped. My mind is with the innocent citizens around the globe that deserve freedom both online and offline.

The problem is that governments don’t only want to censor illegal content that violates human rights—they create legislation that is so broad that it can impact speech and privacy of all. “Don’t you care about the kids?” Yes, I do. I do so much that I’m invested in finding solutions. I also care about all citizens around the globe that deserve an opportunity to live free from a mass surveillance society. If terrorism happens online, I should not be punished by losing my freedom. If drugs are sold online, I should not be punished. I’m not an abuser, I’m not a terrorist, and I don’t engage in illegal behaviors. I refuse to lose freedom because of others’ bad behaviors online.

I want to be clear that on a long enough timeline, the governments will decide that they can be better parents/caregivers than you can if something isn’t done to stop minors from being sexually exploited online. The price will be a complete loss of anonymity, privacy, free speech, and freedom of religion online. I find it rather insulting that governments think they’re better equipped to raise children than parents and caretakers.

So we can’t go backwards—all that we can do is go forward. Those who want to have freedom will find technology to facilitate their liberation. This will lead many over time to decentralized and open protocols. So as far as I’m concerned, this does solve a few of my worries—those who need, want, and deserve to speak freely online will have the opportunity in most countries—but what about online child sexual exploitation?

When I popped up around the decentralized space, I was met with the fear of censorship. I’m not here to censor you. I don’t write code. I couldn’t censor anyone or any piece of content even if I wanted to across the internet, no matter how depraved. I don’t have the skills to do that.

I’m here to start a conversation. Freedom comes at a cost. You must always fight for and protect your freedom. I can’t speak about protecting yourself from all of the Four Horsemen because I simply don’t know the topics well enough, but I can speak about this one topic.

If there was a shortcut to ending online child sexual exploitation, I would have found it by now. There isn’t one right now. I believe that education is the only pathway forward to preventing the crime of online child sexual exploitation for future generations.

I propose a yearly education course for every child of all school ages, taught as a standard part of the curriculum. Ideally, parents/caregivers would be involved in the education/learning process.

Course: - The creation of the internet and computers - The fight for cryptography - The tech supply chain from the ground up (example: human rights violations in the supply chain) - Corporate tech - Freedom tech - Data privacy - Digital privacy rights - AI (history-current) - Online safety (predators, scams, catfishing, extortion) - Bitcoin - Laws - How to deal with online hate and harassment - Information on who to contact if you are being abused online or offline - Algorithms - How to seek out the truth about news, etc., online

The parents/caregivers, homeschoolers, unschoolers, and those working to create decentralized parallel societies have been an inspiration while writing this, but my hope is that all children would learn this course, even in government ran schools. Ideally, parents would teach this to their own children.

The decentralized space doesn’t want child sexual exploitation to thrive. Here’s the deal: there has to be a strong prevention effort in order to protect the next generation. The internet isn’t going anywhere, predators aren’t going anywhere, and I’m not down to let anyone have the opportunity to prove that there is a need for more government. I don’t believe that the government should act as parents. The governments have had a chance to attempt to stop online child sexual exploitation, and they didn’t do it. Can we try a different pathway forward?

I’d like to put myself out of a job. I don’t want to ever hear another story like John Doe #1 ever again. This will require work. I’ve often called online child sexual exploitation the lynchpin for the internet. It’s time to arm generations of children with knowledge and tools. I can’t do this alone.

Individuals have fought so that I could have freedom online. I want to fight to protect it. I don’t want child predators to give the government any opportunity to take away freedom. Decentralized spaces are as close to a reset as we’ll get with the opportunity to do it right from the start. Start the youth off correctly by preventing potential hazards to the best of your ability.

The good news is anyone can work on this! I’d encourage you to take it and run with it. I added the additional education about the history of the internet to make the course more educational and fun. Instead of cleaning up generations of destroyed lives due to online sexual exploitation, perhaps this could inspire generations of those who will build our futures. Perhaps if the youth is armed with knowledge, they can create more tools to prevent the crime.

This one solution that I’m suggesting can be done on an individual level or on a larger scale. It should be adjusted depending on age, learning style, etc. It should be fun and playful.

This solution does not address abuse in the home or some of the root causes of offline child sexual exploitation. My hope is that it could lead to some survivors experiencing abuse in the home an opportunity to disclose with a trusted adult. The purpose for this solution is to prevent the crime of online child sexual exploitation before it occurs and to arm the youth with the tools to contact safe adults if and when it happens.

In closing, I went to hell a few times so that you didn’t have to. I spoke to the mothers of survivors of minors sexually exploited online—their tears could fill rivers. I’ve spoken with political dissidents who yearned to be free from authoritarian surveillance states. The only balance that I’ve found is freedom online for citizens around the globe and prevention from the dangers of that for the youth. Don’t slow down innovation and freedom. Educate, prepare, adapt, and look for solutions.

I’m not perfect and I’m sure that there are errors in this piece. I hope that you find them and it starts a conversation.

I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.

My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.

Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.

I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.

I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.

That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.

In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.

I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.

Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.

If you need help now or later with Nostr projects, reach out. Nostr only—nothing else. Anonymous contact’s fine. Even just a suggestion on how I can pitch in, no project attached, works too. 💜

Creeps or harassment will get blocked or I’ll nuke my simplex code if it becomes a problem.

With the advancement of quantum computers, a new threat emerges for the security of cryptocurrencies and blockchain technologies. These powerful machines have the potential to expose vulnerabilities in traditional cryptographic systems, which could jeopardize the safety of digital wallets. But don’t worry—modern wallets are already equipped to handle this threat with innovative solutions that make your funds nearly impossible to steal, even by a quantum computer. Let’s explore how this works and why you can rest easy.

The Threat of Quantum Computers

To understand how wallets protect us, we first need to grasp what makes quantum computers so dangerous. At the core of most cryptocurrencies, like Bitcoin, lies public and private key cryptography. The public key (or address) is like your bank account number—you share it to receive funds. The private key is like your PIN—it allows you to send funds and must remain secret.

Traditional cryptography, such as the ECDSA algorithm, relies on mathematical problems that are extremely difficult to solve with conventional computers. For instance, deriving a private key from a public key is practically impossible, as it would take millions of years of computation. However, quantum computers, thanks to algorithms like Shor’s, can significantly speed up this process. Theoretically, a sufficiently powerful quantum computer could uncover a private key from a public key in minutes or even seconds.

This is a problem because if someone gains access to your private key, they can send all your funds to their own address. But here’s the good news—modern wallets use a clever solution to render this threat powerless.

How Do Wallets Protect Us?

One of the most effective defenses against quantum computers is the use of one-time addresses in wallets. This means that for every transaction—whether receiving or sending funds—the wallet automatically generates a new public address. The old address, once used, remains in the transaction history but no longer holds any funds, as they are transferred to a new address.

Why Does This Work?

Imagine you’re sending or receiving cryptocurrency. Your wallet creates a new address for that transaction. After the funds are sent or received, that address becomes “used,” and the wallet automatically generates a new one for the next transaction. If a quantum computer manages to derive the private key from the public address of the used address, it will find nothing—because that address is already empty. Your funds are safely transferred to a new address, whose public key has not yet been exposed.

This strategy is known as HD (Hierarchical Deterministic) wallets. It allows the wallet to generate an infinite number of addresses from a single master key (seed) without compromising security. Each new address is unique and cannot be linked to the previous ones, making it impossible to trace your funds, even with a quantum computer.

Automation Makes It Effortless

The best part? You don’t need to worry about this process—it’s fully automated. When you use a modern wallet like MetaMask, Ledger, Trezor, or software wallets for Bitcoin, everything happens behind the scenes. You simply click “receive” or “send,” and the wallet takes care of generating new addresses. There’s no need to understand the complex technical details or manually manage your keys.

For example:

• You want to receive 0.1 BTC. Your wallet provides a new address, which you share with the sender.
• After receiving the funds, the wallet automatically prepares a new address for the next transaction.
• If you send some of the funds, the remaining amount (known as “change”) is sent to another new address generated by the wallet.

This system ensures that public addresses exposed on the blockchain no longer hold funds, making quantum attacks pointless.

Additional Protection: Toward Post-Quantum Cryptography

Beyond one-time addresses, blockchain developers are also working on post-quantum cryptography—algorithms that are resistant to quantum computers. Some blockchain networks are already experimenting with such solutions, like algorithms based on lattices (lattice-based cryptography). These methods don’t rely on the same mathematical problems that quantum computers can solve, offering long-term protection.

In the meantime, one-time addresses combined with current cryptographic standards provide enough security to safeguard your funds until post-quantum solutions become widely adopted.

Why You Shouldn’t Worry

Modern wallets are designed with the future in mind. They not only protect against today’s threats but also anticipate future risks, such as those posed by quantum computers. One-time addresses make exposed public keys useless to hackers, and automation ensures you don’t need to deal with the technicalities. HD wallets, which automatically generate new addresses, make the process seamless and secure for users.

Public key exposure only happens when necessary, reducing the risk of attacks, even from a quantum computer. In conclusion, while quantum computers pose a potential threat, modern wallets already offer effective solutions that make your cryptocurrencies nearly impossible to steal. With one-time addresses and the upcoming adoption of post-quantum cryptography, you can be confident that your funds are safe—today and tomorrow.

Die Satire Muxmäuchenstill von 2004 erzählt die Geschichte des 30-jährigen Mux, der seine Mitbürgern zu mehr Verantwortungsbewusstsein erziehen möchte. Dazu stellt er Raser, Schwarzfahrer, Graffiti-Sprüher, Falschparker, Ladendiebe und Vergewaltiger, konfrontiert sie mit ihrem Verhalten und bestraft sie.

https://soundcloud.com/radiomuenchen/muxmauschenstill-x-interview-mit-jan-henrik-stahlberg?

Als Mitstreiter gewinnt er Arbeits- und Obdachlose. Mux’ fanatische Ein-Mann-Mission wächst zu einem kleinen Unternehmen. Auch privat kann er seinen Moralismus nicht zügeln und erschießt seine Freundin. Am Ende des Films wird er von einem Raser überfahren.

Ab 1. Mai läuft die Fortsetzung in den Kinos: Muxmäuschenstill X: muxfilm.de/. Nach zwanzig Jahre Wachkoma findet sich Mux in einer Welt wieder, die er nicht mehr versteht: dem wunderbaren Neoliberalismus. Wieder möchte Mux die Menschen erziehen. Doch diesmal kämpft er gegen ein System, das alles durchdringt, die Welt spaltet, unsere Lebensgrundlagen zerstört, die Reichen reicher macht und die Armen ärmer. Mux gründet den Muxismus und schart die Aussortierten des Systems um sich.

Drehbuchautor und Hauptdarsteller Jan Henrik Stahlberg führt diesmal auch Regie. Unser Autor Jonny Rieder hat mit Jan Henrik Stahlberg über seinen neuen Film gesprochen. Zunächst wollte er wissen, wo für ihn die Grenze verläuft zwischen Übergriffigkeit und Zivilcourage und wie er Mux hier einordnet.

Before I saw those X right-wing political “influencers” parading their Epstein binders in that PR stunt, I’d already posted this on Nostr, an open protocol. 

“Today, the world’s attention will likely fixate on Epstein, governmental failures in addressing horrific abuse cases, and the influential figures who perpetrate such acts—yet few will center the victims and survivors in the conversation. The survivors of Epstein went to law enforcement and very little happened. The survivors tried to speak to the corporate press and the corporate press knowingly covered for him. In situations like these social media can serve as one of the only ways for a survivor’s voice to be heard. 

It’s becoming increasingly evident that the line between centralized corporate social media and the state is razor-thin, if it exists at all. Time and again, the state shields powerful abusers when it’s politically expedient to do so. In this climate, a survivor attempting to expose someone like Epstein on a corporate tech platform faces an uphill battle—there’s no assurance their voice would even break through. Their story wouldn’t truly belong to them; it’d be at the mercy of the platform, subject to deletion at a whim. Nostr, though, offers a lifeline—a censorship-resistant space where survivors can share their truths, no matter how untouchable the abuser might seem. A survivor could remain anonymous here if they took enough steps. 

Nostr holds real promise for amplifying survivor voices. And if you’re here daily, tossing out memes, take heart: you’re helping build a foundation for those who desperately need to be heard.“

That post is untouchable—no CEO, company, employee, or government can delete it. Even if I wanted to, I couldn’t take it down myself. The post will outlive me on the protocol. 

The cozy alliance between the state and corporate social media hit me hard during that right-wing X “influencer” PR stunt. Elon owns X. Elon’s a special government employee. X pays those influencers to post. We don’t know who else pays them to post. Those influencers are spurred on by both the government and X to manage the Epstein case narrative. It wasn’t survivors standing there, grinning for photos—it was paid influencers, gatekeepers orchestrating yet another chance to re-exploit the already exploited.

The bond between the state and corporate social media is tight. If the other Epsteins out there are ever to be unmasked, I wouldn’t bet on a survivor’s story staying safe with a corporate tech platform, the government, any social media influencer, or mainstream journalist. Right now, only a protocol can hand survivors the power to truly own their narrative.

I don’t have anything against Elon—I’ve actually been a big supporter. I’m just stating it as I see it. X isn’t censorship resistant and they have an algorithm that they choose not the user. Corporate tech platforms like X can be a better fit for some survivors. X has safety tools and content moderation, making it a solid option for certain individuals. Grok can be a big help for survivors looking for resources or support! As a survivor, you know what works best for you, and safety should always come first—keep that front and center.

That said, a protocol is a game-changer for cases where the powerful are likely to censor. During China's # MeToo movement, survivors faced heavy censorship on social media platforms like Weibo and WeChat, where posts about sexual harassment were quickly removed, and hashtags like # MeToo or "woyeshi" were blocked by government and platform filters. To bypass this, activists turned to blockchain technology encoding their stories—like Yue Xin’s open letter about a Peking University case—into transaction metadata. This made the information tamper-proof and publicly accessible, resisting censorship since blockchain data can’t be easily altered or deleted.

I posted this on X 2/28/25. I wanted to try my first long post on a nostr client. The Epstein cover up is ongoing so it’s still relevant, unfortunately.

Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.

Concern

One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.

Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.

Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.

Optimism

The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.

Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.

This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.

Realism

We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.

We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

Não são recentes as táticas da esquerda de tentar reprimir intelectualmente seus opositores na base do deboche, da ironia, do desprezo e do boicote à credibilidade. Até Marx usava ironia para chamar os críticos de "burgueses iludidos". A diferença é que, no século XXI, trocaram o manifesto comunista por threads no Twitter e a dialética por memes de mau gosto.

A Falácia da Superioridade Moral

O debate sobre o "pobre de direita" no Brasil é contaminado por uma premissa tácita da esquerda: a ideia de que classes baixas só podem ter consciência política se aderirem a pautas progressistas. Quem ousa divergir é tratado como "traidor de classe", "manipulado", "ignorante", ou até vítimas de deboches como alguma pessoa com um qi em temperatura ambiente repetir diversas vezes "não é possível que ainda exista pobre de direita", "nunca vou entender pobre de direita", ou "pobre de direita é muito burro, rico eu até entendo", como se o autor dessas frases fosse o paladino dos mais oprimidos e pobres. Esse discurso, porém, não resiste a uma análise empírica, histórica ou sociológica.

---

Contexto Histórico: A Esquerda e o Mito do "Voto Consciente"

A noção de que o pobre deve votar na esquerda por "interesse de classe" é herança do marxismo ortodoxo, que via a política como mero reflexo da posição econômica. No entanto, a realidade é mais complexa:

• Dados do Latinobarómetro (2022): 41% dos brasileiros de baixa renda (até 2 salários mínimos) apoiam redução de impostos e maior liberdade econômica — pautas tradicionalmente associadas à direita.
• Pesquisa IPEC (2023): 58% dos pobres brasileiros priorizam "segurança pública" como principal demanda, acima de "distribuição de renda".

Esses números não são acidentais. Refletem uma mudança estrutural: o pobre moderno não é mais o "operário industrial" do século XX, mas um empreendedor informal, motorista de app, ou microempresário — figuras que valorizam autonomia e rejeitam paternalismo estatal. Eles dizem não entender o pobre de direita e que nunca vai entendê-los, mas o fato é que não entendem porque nunca conversaram com um sem fazer cara de psicólogo de posto de saúde. Sua "preocupação" é só uma máscara para esconder o desprezo por quem ousa pensar diferente do seu manual de "oprimido ideal".

Se ainda não entenderam:

Direita ≠ rico: Tem gente que trabalha 12h/dia e vota em liberal porque quer ser dono do próprio negócio, não pra pagar mais taxação pra você postar meme no Twitter.
Acham que são o Sherlock Holmes da pobreza: o palpite de que "o pobre é manipulado" é tão raso quanto sua compreensão de economia básica.

---

A Psicologia por Trás do Voto Conservador nas Periferias

A esquerda atribui o voto pobre em direita a "falta de educação" ou "manipulação midiática". Essa tese é não apenas elitista, mas cientificamente falsa:

Análise Psicológica Básica (para você que se acha o Paulo Freire):
- Síndrome do Branco Salvador: Acha que o pobre é uma criatura tão frágil que precisa de você pra pensar. Spoiler: ele não precisa.
- Viés da Superioridade Moral: "Se você é pobre e não concorda comigo, você é burro". Parabéns, recriou a escravidão intelectual.
- Efeito Dunning-Kruger: Não sabe o que é CLT, mas dá palpite sobre reforma trabalhista.

• Estudo da Universidade de São Paulo (USP, 2021): Entre moradores de favelas, 63% associam políticas de segurança dura (como "bandido bom é bandido morto") à proteção de seus negócios e famílias. Para eles, a esquerda é "branda demais" com o crime.
• Pesquisa FGV (2020): 71% dos trabalhadores informais rejeitam aumentos de impostos, mesmo que para financiar programas sociais. Motivo: já sofrem com a burocracia estatal para legalizar seus negócios.

Esses dados revelam uma racionalidade prática: o pobre avalia políticas pelo impacto imediato em sua vida, não por abstrações ideológicas. Enquanto a esquerda fala em "reforma estrutural" e tenta importar discursos estrangeiros para debate, por exemplo, o tema irrelevante do pronome neutro, ele quer resolver problemas como:
- Violência (que afeta seu comércio);
- Impostos (que consomem até 40% do lucro de um camelô);
- Burocracia (que impede a legalização de sua barraca de pastel).

---

Religião, Valores e a Hipocrisia do "Ateísmo de Redes Sociais"

A esquerda subestima o papel da religião na formação política das classes baixas. No Brasil, 76% dos evangélicos são pobres (Datafolha, 2023), e suas igrejas promovem valores como:
- Família tradicional (contra pautas progressistas como ideologia de gênero em escolas);
- Auto-responsabilidade (ênfase em "trabalho duro" em vez de assistencialismo).

Exemplo Concreto:
Nas favelas de São Paulo, pastores evangélicos são frequentemente eleitos a cargos locais com plataformas anticrime e pró-mercado. Para seus eleitores, a esquerda urbana (que defende descriminalização de drogas e críticas à polícia) representa uma ameaça ao seu estilo de vida.

A Esquerda e seu Desprezo pela Autonomia do Pobre

O cerne do debate é a incapacidade da esquerda de aceitar que o pobre possa ser autônomo. Algumas evidências:

O Caso dos Empreendedores Informais

• Segundo o IBGE (2023), 40% dos trabalhadores brasileiros estão na informalidade. Muitos veem o Estado como obstáculo, não aliado. Políticas de direita (como simplificação tributária) são mais atraentes para eles que o Bolsa Família.

A Ascensão do Conservadorismo Periférico

• Pessoas assim tem um pensamento simples. Sua mensagem: "Queremos empreender, não depender de político."

A Rejeição ao "Vitimismo"

• Pesquisa Atlas Intel (2022): 68% dos pobres brasileiros rejeitam o termo "vítima da sociedade". Preferem ser vistos como "lutadores".

---

A projeção freudiana "o pobre é burro porque eu sou inteligente"

O deboche esquerdista esconde um complexo de inferioridade disfarçado de superioridade moral. É a Síndrome do Salvador em sua forma mais patética:
- Passo 1: Assume-se que o pobre é um ser desprovido de agência.
- Passo 2: Qualquer desvio da narrativa é atribuído a "manipulação da elite".
- Passo 3: Quem critica o processo é chamado de "fascista".

Exemplo Prático:
Quando uma empregada doméstica diz que prefere o livre mercado a programas sociais, a esquerda não pergunta "por quê?" — ela grita "lavagem cerebral!". A ironia? Essa mesma esquerda defende a autonomia feminina, exceto quando a mulher é pobre e pensa diferente.

Dados Globais: O Fenômeno Não é Brasileiro

A ideia de que "pobre de direita" é uma anomalia é desmentida por evidências internacionais:

• Estados Unidos: 38% dos eleitores com renda abaixo de US$ 30k/ano votaram em Trump em 2020 (Pew Research). Motivos principais: conservadorismo social e rejeição a impostos. A esquerda: "vítimas da falsa consciência". Mais um detalhe: na última eleição de 2024, grande parte da classe "artística" milionária dos Estados Unidos, figuras conhecidas, promoveram em peso a Kamala Harris, do Partido Democrata. Percebe como a esquerda atual é a personificaçãoda burguesia e de só pensar na própria barriga?
• Argentina: Javier Milei, libertário radical, quando candidato, tinha forte apoio nas villas miseria (favelas). Seu lema — "O estado é um parasita" — ressoa entre quem sofria com inflação de 211% ao ano.
• Índia: O partido BJP (direita nacionalista) domina entre os pobres rurais, que associam a esquerda a elites urbanas desconectadas de suas necessidades.

A história que a esquerda tenta apagar: pobres de direita existem desde sempre

A esquerda age como se o "pobre de direita" fosse uma invenção recente do MBL, mas a realidade é que classes baixas conservadoras são regra, não exceção, na história mundial:
- Revolução Francesa (1789): Camponeses apoiaram a monarquia contra os jacobinos urbanos que queriam "libertá-los".
- Brasil Imperial: Escravos libertos que viraram pequenos proprietários rurais rejeitavam o abolicionismo radical — queriam integração, não utopia.

Tradução:
Quando o pobre não segue o script, a esquerda inventa teorias conspiratórias.

A Hipocrisia da Esquerda Urbana e Universitária

Enquanto acusa o pobre de direita de "alienado", a esquerda brasileira é dominada por uma elite desconectada da realidade periférica:

• Perfil Socioeconômico: 82% dos filiados ao PSOL têm ensino superior completo (TSE, 2023). Apenas 6% moram em bairros periféricos.
• Prioridades Descoladas: Enquanto o pobre debate segurança e custo de vida, a esquerda pauta discussões como "linguagem não-binária em editais públicos" — tema irrelevante para quem luta contra o desemprego. Os grandes teóricos comunistas se reviram no túmulo quando veem o que a esquerda se tornou: não debatem os reais problemas do Brasil, e sim sobre suas próprias emoções.

"A esquerda brasileira trocou o operário pelo influencer progressista. O pobre virou um personagem de campanha, não um interlocutor real."

A diversidade de pensamento que a esquerda não suporta

A esquerda prega diversidade — desde que você seja diverso dentro de um checklist pré-aprovado. Pobre LGBTQ+? Herói. Pobre evangélico? Fascista. Pobre que abre MEI? "Peão do capitalismo". A realidade é que favelas e periferias são microcosmos de pluralidade ideológica, algo que assusta quem quer reduzir seres humanos a estereótipos.

Respostas aos Argumentos Esquerdistas (e Por que Falham)

"O pobre de direita é manipulado pela mídia!"

• Contradição: Se a mídia tradicional é dominada por elites (como alegam), por que grandes veículos são abertamente progressistas? A Record (evangélica) é exceção, não regra.

Contradição Central:
Como explicar que, segundo o Banco Mundial (2023), países com maior liberdade econômica (ex.: Chile, Polônia) reduziram a pobreza extrema em 60% nas últimas décadas, enquanto modelos estatizantes (ex.: Venezuela, Argentina com o governo peronista) afundaram na miséria? Simples: a esquerda prefere culpar o "neoliberalismo" a admitir que o pobre com o mínimo de consciência quer emprego, não esmola.

Dado que Machuca:
- 71% das mulheres da periferia rejeitam o feminismo radical, associando-o a "prioridades distantes da realidade" (Instituto Locomotiva, 2023).

"Ele vota contra os próprios interesses!"

• Falácia: Pressupõe que a esquerda define o que é o "interesse do pobre". Para um pai de família na Cidade de Deus, ter a boca de fogo fechada pode ser mais urgente que um aumento de 10% no Bolsa Família.

O pobre de direita não é uma anomalia. É o produto natural de um mundo complexo onde seres humanos têm aspirações, medos e valores diversos. Enquanto a esquerda insiste em tratá-lo como um projeto fracassado, ele está ocupado:
- Trabalhando para não depender do governo.
- Escolhendo religiões que dão sentido à sua vida.
- Rejeitando pautas identitárias que não resolvem o custo do gás de cozinha.

"É falta de educação política!"

• Ironia: Nos países nórdicos (modelo da esquerda), as classes baixas são as mais conservadoras. Educação não correlaciona com progressismo.

Por que o Debuste Precisa Acabar

A insistência em descredibilizar o pobre de direita revela um projeto de poder fracassado. A esquerda, ao substituir diálogo por deboche, perdeu a capacidade de representar quem mais precisaria dela. Enquanto isso, a direita — nem sempre por virtude, mas por pragmatismo — capturou o descontentamento de milhões com o status quo.

O pobre de direita existe porque ele não precisa da permissão do rico de esquerda para pensar. A incapacidade de entender isso só prova que a esquerda é a nova aristocracia.

Último Dado: Nas eleições de 2022, Tarcísio de Freitas (direita) venceu em 72% das favelas de São Paulo. O motivo? Seu discurso anti-burocracia e pró-microempreendedor.

A mensagem é clara: o pobre não é um projeto ideológico. É um agente político autônomo — e quem não entender isso continuará perdendo eleições.

A esquerda elitista não odeia o pobre de direita por ele ser "irracional". Odeia porque ele desafia o monopólio moral que ela construiu sobre a miséria alheia. Enquanto isso, o pobre segue sua vida, ignorando os berros de quem acha que sabem mais da sua vida que ele mesmo.

Pergunta Retórica (Para Incomodar):
Se a esquerda é tão sábia, por que não usa essa sabedoria para entender que pobre também cansa de ser tratado como cachorro que late no ritmo errado?

"Show me the incentives, and I'll show you the outcome"[^mungerquote].

"Even bacteria respond to motivation." ~[^dufrene2020][^amoedo2024].

Introduction

In Austrian economics, time preference refers to the value individuals place on present consumption versus future consumption [^rothbard1993man]. A society with a lower time preference is more inclined to save, invest, and plan for the long term, thereby fostering progress and stability [^ammous2018]. In contrast, a society with a higher time preference tends toward immediate consumption rather than investment — or invests without a true understanding of its purpose — leading to short-term planning and a gradual drift from foundational societal values, traditions, and culture [^hoppe2001].

The definition of investment is the process of allocating resources to productive activities, prioritizing future gains over immediate consumption. It involves capital accumulation and is key to economic growth, as individuals delay gratification to increase future value. This approach underlies capital formation and enhances an economy's production capacity, aligning with lower time preference and fostering long-term prosperity [^mises1998].

With a foundational understanding of time preference and investment, we can begin to examine what motivates people today. Given the prevalence of high time preference in modern society, the government can capitalize on this tendency by offering immediate handouts and benefits, satisfying the population's desire for instant gratification, often at the expense of long-term prosperity and future gains. This tendency is also mirrored in mainstream media, where a focus on sensational, attention-grabbing stories diverts focus from deeper, structural issues. By amplifying polarizing narratives [^gentzkow2006media], often tied to social identity or lifestyle differences, the government and media create a cycle of constant engagement and distraction, steering public attention towards short-term controversies and away from underlying economic or social policy issues [^caplan2001rational].

Debt & Fractional-Reserve Banking

A common denominator that repeatedly emerges in such destructive behavior promoted by governments is the issue of money. As money drives the world, understanding and following its flow not only reveals how it operates but also uncovers those who wield control over it, and how human behavior is driven by it.

Money is a broad term encircling all assets that can be used for exchange, storage, and valuation, covering both physical and digital forms [^ammous2023]. Cash is a subset of money, referring specifically to physical currency, such as coins and notes.

The process of money creation, typically managed by governments and central banks, is the foundation of economic dependency within the financial system. In most economies, central banks control currency creation through mechanisms like open market operations and debt. For instance, when a central bank, such as the Federal Reserve, issues new currency, it does so by purchasing government securities from commercial banks, thus adding currency to the economy. However, this transaction is not debt-free; it obliges the government to repay the borrowed amount with interest.

In common words, the process of creating money is as follows: the government request to the central bank a certain amount of money to be printed in borrowing form. The central bank then creates that money, out of thin air, on the promise that the government will repay the central bank down the road. Since the government does not produce anything, in order to repay the central bank, the government then sells the debt via bonds to anyone who would like to buy the government debt. In even more simple words: the government and central bank creates money out of thin air based on debt [^ammous2021].

The issue with money creation is not only by the fact that it was created out of thin air, but because money creation has other issues tied to it: the debt, the creation of fractional-reserve monetary system, inflation, and interest.

This foundational reliance on debt, since it is present in the very beginning of money creation, renders the entire monetary system debt-dependent. Therefore, saving and investing within such a system becomes questionable, as the system's nature opposes the principles of sustainable wealth accumulation, thus leading human behavior not to save but to spend.

A fractional-reserve monetary system is a banking structure in which banks retain only a small fraction of their depositors' funds — historically around 10%, but today often as low as 1% [^bundesbank2024] — while lending out or investing the remainder. This setup allows banks to expand the money supply and stimulate economic activity through a process known as deposit expansion [^federalreserve1975modern]. Deposit expansion occurs when banks effectively treat a portion of deposited funds as new money, multiplying the original deposit base. For example, if a bank holds deposits totaling 1 million euros, it can lend out up to 1.9 million euros, as long as it maintains 10% of the initial deposit in reserve. This cycle can repeat, enabling banks to increase the total money supply to infinity, but the "Modern Money Mechanics: A Workbook on Bank Reserves and Deposit Expansion" and government applying it recommends not doing it above 9 times the original deposit value [^federalreserve1975modern].

To make matters worse, inflation and interest exacerbate the problems inherent in this monetary system. Interest is a foundational element of the system, initially intended to address the original debt incurred by the government. In economic terms, interest represents the "price" of time preference, a premium placed on present goods over future goods. To illustrate the impact of interest, consider the cost of a house in today's system: a house priced at 500,000 euros with a 4% variable interest rate ends up costing around 860,000 euros over 30 years, with 360,000 euros paid in interest alone.

Inflation, on the other hand, is the increase in the money supply — money printing — and can only be truly calculated by M2[^1] money supply metric. Inflation erodes the value of both assets and earned income, as each new unit of currency devalues existing money. This devaluation impacts not only the purchasing power of savings but also the real cost of goods and services over time, reducing the long-term value of assets people believe they own.

The government

Operating within a monetary system stretched beyond its limitations, the government faces the dual challenges of controlling inflation and satisfying its growing spending demands. To fund its expenditures, the government often provides public benefits — subsidies, "free" healthcare, public transport, security, military, and welfare in general — to justify continual spending and cultivate public support - via voting, in most democratic countries.

Welfare and most government programs redistribute wealth from producers to non-producers, fostering dependency on the state. Over time, this erodes individual sovereignty and expands government control, restricting freedom, and reducing people to slaves or cash cows.

The government justifies taxes as payment for welfare and public services, but also claims they curb inflation by reducing the need to print money. The logic is that by reclaiming taxpayer money, the money supply is controlled. However, this is misleading, especially when the government can print money at will, making taxation on such currency inherently flawed.

Taxes are extracted via coercion - violence - by the government onto the population. The government then decides where to allocate this money, based on their guess of what the population needs, excluding private preferences. Therefore, taxes are not an incentive to accumulate, not even to work more. Taxes are an incentive to do right the opposite: do not save and do not work more.

Another tactic the government employs is to create crises that it alone can "solve", thus requiring more taxes or funding. Recent examples include crises like COVID-19, the "green" agenda, and initiatives to combat climate change[^2]. In each case, the government presents itself as the sole solution, yet solving these crises inevitably demands additional resources — in the form of increased taxation.

Even minimal critical thinking would prompt one to question the true necessity of taxes in a government that owns and controls the money printer. Given what we now understand, if you were in the government's position, would you willingly relinquish control of money creation by tying it to something like gold, empowering people to become smarter, independent, and wealthy?

The government, through various channels — media, education, propaganda, welfare, and government subsidies — ensures that people remain obedient and uninformed. It keeps them financially constrained by increasing taxes and imposing extensive regulations, while fostering dependency through handouts, welfare, and other social programs. The government is the only entity that, by law, can use violence and coercion without prosecution [^rothbard2009].

"Anyone who, although human, is by nature not yours but someone else's"[^ambler1987].

It is therefore unsurprising that many live in a state akin to enslavement, reflecting a mindset shaped by constant dependency. It is no wonder that people are discouraged from having children, as they can barely support themselves. Nor is it surprising that individuals might question the need to continue their bloodline, believing in the illusory value of "fake money" [^kiyosaki2019] and trusting present "investments" and the government to provide a pension in old age. And it's certainly not surprising to see people asking the government for solutions to every problem, when the government leaves them no viable alternatives.

"Show me the incentives, and I'll show you the outcome"[^mungerquote].

That statement serves as a powerful tool for understanding and addressing complex issues. When observing behaviors that may appear unusual — such as individuals identifying as "trans-species," a phenomenon linked to mental health concerns [^pinna2022] — it's essential to consider the underlying incentives. Who benefits most from a society in which individuals remain financially constrained, dependent, and uninformed? A fiat-based monetary system functions as a modern form of economic control, keeping people poor by design. Taxes, effectively a penalty for productivity, contrast sharply with welfare programs, which often reward dependency and reinforce reliance on the government. Meanwhile, government narratives and selective information shape public beliefs, protecting institutional interests and discouraging critical inquiry[^3].

Conclusion

Like the fungus that infects in parasitic way an ant's nervous system - Ophiocordyceps Unilateralis -, rendering it a zombie [^britannica2024] controlled by an external force, similarly, modern bureaucracies exploit the mechanisms of fiat money, debt, and taxation [^rothbard2009] to maintain control over individuals, steering them away from self-reliance and critical thinking toward a state of perpetual dependence.

The parallels are striking: just as the fungus manipulates the ant's behavior to secure its reproduction, governments manipulate public perception, creating crises, shaping incentives, and fostering dependence[^rothbard2009] through welfare programs[^caplan2001rational], inflated debt[^ammous2018], and coercive taxation. These mechanisms suppress individuality, reduce productivity, and shift power further into centralized hands[^gentzkow2006media], leaving citizens "zombified", detached from purpose and independence.

"Even bacteria respond to motivation."[^dufrene2020]

If tolerated — even by you, dear reader — this parasitic cycle will continue to erode humanity's dignity and potential. The solution lies in reclaiming agency by building a society grounded in sound money, meaningful productivity, and spiritual and cultural foundations that connect us to higher purposes. As warned in Jeremiah 17:5 [^4], trusting fallible human systems leads to enslavement. True freedom comes from rejecting exploitative bureaucracies and embracing systems aligned with truth, autonomy, and resilience.

Another way is to fully understand the system and opt out. This requires mastering the rules and using them to your advantage. If legal avenues exist to avoid taxation, expropriation, eminent domain, or government coercion, then the first step is to change the game for yourself.

The monetary system and government incentives shape human behavior, influencing those who allow themselves to be controlled by them.

The PCL-R total scores of the CAH and general offenders were virtually the same but much higher than those of the community sample. However, the CAH group had extraordinarily high scores on the Interpersonal/Affective facets yet relatively low scores on the Lifestyle/Antisocial facets. LPA identified the expected four latent classes, with most CAH men located within the Callous-Conning class. Conclusions The results of this study provide unique information about the psychopathic propensities of a sample of state violators of human rights.

Solar Power Tips for a Sustainable Remote Home Office

As more professionals transition to remote work, the need for sustainable and cost-effective solutions has never been greater. One of the most effective ways to reduce your ecological impact and lower energy costs is by harnessing the sun's power—specifically, solar energy.

Solar power is becoming increasingly popular among remote workers, providing a renewable energy source for residences with a home office setup. It helps reduce reliance on fossil fuels, and offers the potential for significant long-term savings.

This blog will list the benefits of using solar power in a remote home office environment. Whether you want to reduce your carbon footprint or reduce your energy expenses, the information will guide you in creating a more sustainable design for a productive home office. Choosing the Right Solar Panels Building a solar-powered home office starts with picking the right solar panels. You can choose from traditional photovoltaic panels to sleek solar shingles that blend with your roof's design.

Recent advancements in solar technology have introduced more compact and efficient panels, making it easier than ever to generate significant power, even in smaller spaces.

When choosing solar panels, prioritize efficiency ratings and durability. High-efficiency panels, such as monocrystalline options, can produce more energy with less surface area. They are ideal if you have limited roof space.

Aesthetics can also play a role, particularly if you want your home office to maintain a modern, professional appearance. For example, solar shingles offer a subtler alternative to standard panels while providing comparable energy production. Essential solar power components Setting up a fully functional solar-powered home office requires more than just panels. Below are the essential components to consider:

Inverters

Solar panels create direct current (DC), but most home appliances run on alternating current (AC). Inverters convert DC to AC, so you can use solar power. Look for high-quality inverters, such as micro-inverters, which optimize the output of each panel individually.

Batteries

Energy storage is critical because solar power is not always available. Solar batteries let you save extra energy made during the day so you can use it at night or when it is cloudy. Consider opting for lithium-ion batteries due to their high energy density, long lifespan, and relatively small size.

Mounting hardware

Proper installation is key to getting the most energy from your solar panels and making sure they can handle tough weather. Adjustable mounts let you place your panels to get the most sunlight and ensure they last over time. Benefits of Solar Power in a Home Office You may wonder: why is solar power for a home office such a big deal? Here are the reasons why: Cost savings and environmental impact One of the biggest benefits of using solar power in your home office is the potential to save a lot of money. Making your electricity can help you reduce or even eliminate your monthly energy bills.

The average owner can save between $10,000 and $30,000 over the lifespan of a solar energy system, depending on their location and system size. Plus, federal tax credits, state incentives, and net metering programs can lower both the initial and ongoing costs of going solar. Reliability and independence Solar power also provides unmatched reliability and independence, particularly in areas prone to power outages. Coupling your solar panels with a high-capacity battery storage system allows you to maintain power for essential devices during power cuts.

It becomes a critical advantage if you need to keep your computers, internet, and other tools working to stay productive.

Solar energy also frees you from relying on the power grid, which is especially helpful if you live in rural or remote areas where power may be less reliable or more expensive. Additional Tips for a Sustainable Home Office Maximize your home office with these practical ways: Complementary green technologies Consider incorporating complementary green technologies into your home office, such as:

Smart thermostats

Devices like the Nest or Ecobee learn your habits and adjust the temperature to maximize comfort while minimizing energy usage. A smart thermostat regulates heating and cooling based on your schedule, significantly reducing your energy use and costs.

Energy monitors

Tools like the Sense Home Energy Monitor help track energy usage across your home. You can identify energy-draining devices to make better decisions about allocating and conserving power and optimizing your solar system's efficiency.

LED lighting

Transitioning to LED bulbs uses less energy and makes your lights last longer. They further lower replacement costs and waste. Outdoor solar solutions Sustainability does not have to stop at your office door. The following outdoor solar-powered devices can enhance the eco-friendliness of your entire home environment:

Solar-powered garden lights

These lights use built-in solar panels to charge during the day and illuminate your outdoor spaces at night. They are perfect for adding ambiance to your yard or improving visibility along pathways without increasing your electricity bill.

Solar security cameras

Protect your property with solar-powered security cameras. They are self-sufficient and eliminate the need for extensive wiring.

Solar water features

From fountains to birdbaths, solar-powered water features add aesthetic appeal to your garden while relying entirely on renewable energy. Shine Bright at Home Embracing solar power for your home office is a smart step toward a greener, more cost-effective future. Choosing efficient solar panels, integrating essential components like inverters and batteries, and pairing them with complementary green technologies can help you create a sustainable workspace that aligns with modern, eco-conscious values.

If you're considering finding a home in Laguna, Philippines, solar energy becomes an even more valuable investment. With Laguna’s growing residential developments, eco-friendly communities, and abundant sunlight, homeowners can take full advantage of renewable energy to lower electricity costs and reduce their carbon footprint. Many new housing projects in Laguna also emphasize sustainability, making it easier to integrate solar solutions into your home.

Investing in solar power is more than a commitment to the environment—it is a long-term strategy for saving money and boosting reliability in your day-to-day work life. With these tips, you are well on your way to creating a home office that works as hard for the planet as you do.

There is something quietly rebellious about stacking sats. In a world obsessed with instant gratification, choosing to patiently accumulate Bitcoin, one sat at a time, feels like a middle finger to the hype machine. But to do it right, you have got to stay humble. Stack too hard with your head in the clouds, and you will trip over your own ego before the next halving even hits.

Small Wins

Stacking sats is not glamorous. Discipline. Stacking every day, week, or month, no matter the price, and letting time do the heavy lifting. Humility lives in that consistency. You are not trying to outsmart the market or prove you are the next "crypto" prophet. Just a regular person, betting on a system you believe in, one humble stack at a time. Folks get rekt chasing the highs. They ape into some shitcoin pump, shout about it online, then go silent when they inevitably get rekt. The ones who last? They stack. Just keep showing up. Consistency. Humility in action. Know the game is long, and you are not bigger than it.

Ego is Volatile

Bitcoin’s swings can mess with your head. One day you are up 20%, feeling like a genius and the next down 30%, questioning everything. Ego will have you panic selling at the bottom or over leveraging the top. Staying humble means patience, a true bitcoin zen. Do not try to "beat” Bitcoin. Ride it. Stack what you can afford, live your life, and let compounding work its magic.

Simplicity

There is a beauty in how stacking sats forces you to rethink value. A sat is worth less than a penny today, but every time you grab a few thousand, you plant a seed. It is not about flaunting wealth but rather building it, quietly, without fanfare. That mindset spills over. Cut out the noise: the overpriced coffee, fancy watches, the status games that drain your wallet. Humility is good for your soul and your stack. I have a buddy who has been stacking since 2015. Never talks about it unless you ask. Lives in a decent place, drives an old truck, and just keeps stacking. He is not chasing clout, he is chasing freedom. That is the vibe: less ego, more sats, all grounded in life.

The Big Picture

Stack those sats. Do it quietly, do it consistently, and do not let the green days puff you up or the red days break you down. Humility is the secret sauce, it keeps you grounded while the world spins wild. In a decade, when you look back and smile, it will not be because you shouted the loudest. It will be because you stayed the course, one sat at a time. \ \ Stay Humble and Stack Sats. 🫡

As new technologies reshape finance, the traditional banking model faces fresh competition. Let's take a closer look at how the two ecosystems compare today.

What happens when centralized institutions meet decentralized protocols? A transformation of financial services is already underway — and users are at the center of it.

Traditional Banking: Established, Yet Rigid

Traditional banks like JPMorgan Chase, HSBC, and Deutsche Bank have built vast infrastructures over decades. They offer deposit insurance, personal loans, mortgages, and extensive regulatory compliance. Trust, scale, and government support are their major strengths.

However, these institutions often struggle with agility. Opening an international account or sending a cross-border payment can take days and involve considerable fees. Innovations like digital onboarding and instant payments are arriving slowly, hampered by regulatory complexity and legacy systems.

DeFi Platforms: Agile, Accessible, but Risky

By contrast, DeFi protocols such as Uniswap (decentralized exchange), Aave (decentralized lending), and Compound (decentralized borrowing) offer near-instant services, accessible globally 24/7.

DeFi users maintain custody of their own assets. No bank approvals, no office hours. Fees are often lower, and yields can be attractive. Smart contracts automatically execute transactions, removing human bottlenecks.

But DeFi isn't without risks. Without insurance, users are exposed to smart contract bugs, hacks, and protocol failures. Regulatory protections are minimal, and scams can proliferate among unverified projects.

The Bridge Between Worlds: Emerging Hybrids

Interestingly, some traditional players are exploring DeFi-like services. Societe Generale issued tokenized bonds on Ethereum. ING is researching zero-knowledge proofs for financial privacy. Meanwhile, crypto-friendly banks like Silvergate have pioneered instant settlement networks inspired by blockchain efficiency.

The future may not be a winner-takes-all scenario but a convergence: decentralized technology improving traditional services, while banks offer compliant, user-friendly access to digital assets.

Beyond Banking Conference by WeFi: Charting the Future

The ongoing fusion of DeFi and traditional finance will take center stage at the upcoming Beyond Banking Conference by WeFi. Thought leaders and innovators will explore how transparency, smart contracts, and decentralized trust models are redefining global finance.

As these worlds collide, the real question isn't about winners — it's about how finance can evolve to serve a broader, more connected world.

In Jericoacoara, Brazil, a beach town famed for its natural beauty and vibrant tourism, an innovative project is reshaping how locals and visitors think about money. Praia Bitcoin is an ambitious initiative to build a circular economy powered entirely by Bitcoin.

Launched in 2021 by entrepreneur Fernando Motolese, Praia Bitcoin was inspired by the Bitcoin Beach project in El Zonte, El Salvador. The vision is simple: create a self-sustaining Bitcoin economy where businesses and individuals use Bitcoin everyday in place of fiat money.

This idea holds special significance in Jericoacoara, where traditional banking services are scarce. The town lacks even basic infrastructure like ATMs, making financial inclusion a pressing need. With Praia Bitcoin, Bitcoin isn’t just a store of value—it’s a tool to empower a community and connect it to the global economy.

Transforming Jericoacoara with Bitcoin

Since its inception, Praia Bitcoin has worked to foster Bitcoin adoption in the area. Starting with a modest donation of 0.02 BTC, Fernando and his team have built a thriving ecosystem:

• Over 40 businesses now accept Bitcoin, ranging from souvenir shops and tour operators to beach vendors.
• Local students have received Bitcoin-loaded tap-to-pay, Bolt Cards, to use in their daily lives.
• Creative initiatives like “Bitcoin Banana Day” or "Frutas por Sats" (fruits for sats) where children buy fruits for 10 satoshis at school, have brought global attention to the project.

Praia Bitcoin’s success isn’t just about the adoption numbers, it’s about the stories. Families use Bitcoin to shop, business owners save on transaction fees, and children are learning the value of sound money at an early age.

LNbits - The Technology Behind Praia Bitcoin

Creating an economy on Bitcoin’s Lightning Network requires more than enthusiasm, it needs robust tools that are easy to use and adaptable to local needs. That’s where LNbits comes in.

Fernando and the Praia Bitcoin team have used LNbits’ open-source software to solve practical challenges and scale the project. With its modular design, LNbits provides tools that allow Praia Bitcoin to:

• Set Up Wallets: Community members receive user-friendly wallets that connect seamlessly to the Lightning Network, enabling fast, low-cost transactions.
• Issue BoltCards: Using LNbits’ BoltCard extension, the team has distributed NFC-enabled cards, allowing tap-to-pay functionality that makes Bitcoin payments as simple as using a credit card.
• Enable Flexible Payments: The project utilizes LNbits’ Point of Sale TPoS extension that allows merchants to easily receive Lightning Network payments.

Breaking Records, Building Community

Fernando doesn’t just implement solutions, he pushes boundaries. One of his most remarkable achievements was an attempt to set a world record for the most Lightning Network payments in the shortest amount of time. Over the course of one afternoon, 100 children in Jericoacoara received payments of 21,000 satoshis each, demonstrating the scalability and speed of Lightning-powered transactions.

This wasn’t just a technical feat, it was a community moment. The event showed how Bitcoin could serve as a tool for engagement, education, and empowerment, all while highlighting the possibilities of using the Lightning Network for real-world applications.

A Collaborative Approach to Innovation

One of the unique strengths of LNbits is its ability to evolve based on community feedback. While Fernando Motolese and Praia Bitcoin operate independently, their insights have helped refine the LNbits platform.

For example, Fernando’s need for a PIN-less ATM functionality led the LNbits team to implement that feature in the TPoS extension, that had the functionality but required a security PIN. This kind of collaboration isn’t about formal partnerships. It’s about how an open-source ecosystem thrives when real-world needs drive innovation.

The feedback loop between users like Fernando and developers ensures LNbits remains practical and relevant—not just for Praia Bitcoin but for countless other projects worldwide.

The Ripple Effect of Praia Bitcoin

Praia Bitcoin is a case study in what’s possible when Bitcoin meets a strong vision. By leveraging Bitcoin, the Lightning Network and LNbits, the project has redefined financial access in Jericoacoara, proving that small communities can lead big innovations.

For LNbits, Praia Bitcoin showcases the value of adaptable, open-source solutions. Whether it’s creating wallets, enabling NFC payments, or refining tools for real-world use, LNbits provides the infrastructure that makes projects like Praia Bitcoin possible.

But beyond the technical achievements, Praia Bitcoin reminds us of the human impact of Bitcoin adoption. It’s about children buying their first bananas with satoshis, families running businesses with lower fees, and a community connecting to a global financial network for the first time.

Conclusion

Praia Bitcoin’s journey is only getting started and its success is inspiring similar initiatives worldwide. For LNbits, being part of this story, is a testament to the power of the software and of open-source collaboration.

If you’re ready to build the future of Bitcoin adoption, LNbits offers the tools to turn ideas into impact.

Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.

Part One: 2029–2032

• 2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.

• 2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.

• 2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.

• 2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.

• 2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.

Time Jump: 2032–2047

• Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.

Part Two: 2047

• 2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.

• 2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.

• 2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.

Key Differences

• Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
• Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
• Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.

This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

"Malcolm Forbes recounts that a lady, wearing a faded cotton dress, and her husband, dressed in an old handmade suit, stepped off a train in Boston, USA, and timidly made their way to the office of the president of Harvard University. They had come from Palo Alto, California, and had not scheduled an appointment. The secretary, at a glance, thought that those two, looking like country bumpkins, had no business at Harvard.
— We want to speak with the president — the man said in a low voice.
— He will be busy all day — the secretary replied curtly.
— We will wait.
The secretary ignored them for hours, hoping the couple would finally give up and leave. But they stayed there, and the secretary, somewhat frustrated, decided to bother the president, although she hated doing that.
— If you speak with them for just a few minutes, maybe they will decide to go away — she said.
The president sighed in irritation but agreed. Someone of his importance did not have time to meet people like that, but he hated faded dresses and tattered suits in his office. With a stern face, he went to the couple.
— We had a son who studied at Harvard for a year — the woman said. — He loved Harvard and was very happy here, but a year ago he died in an accident, and we would like to erect a monument in his honor somewhere on campus.

— My lady — said the president rudely —, we cannot erect a statue for every person who studied at Harvard and died; if we did, this place would look like a cemetery.

— Oh, no — the lady quickly replied. — We do not want to erect a statue. We would like to donate a building to Harvard.

The president looked at the woman's faded dress and her husband's old suit and exclaimed:

— A building! Do you have even the faintest idea of how much a building costs? We have more than seven and a half million dollars' worth of buildings here at Harvard.

The lady was silent for a moment, then said to her husband:

— If that’s all it costs to found a university, why don’t we have our own?

The husband agreed.

The couple, Leland Stanford, stood up and left, leaving the president confused. Traveling back to Palo Alto, California, they established there Stanford University, the second-largest in the world, in honor of their son, a former Harvard student."

President Trump has intensified immigration enforcement, likening it to a wartime effort. Despite pouring resources into the U.S. Immigration and Customs Enforcement (ICE), arrest numbers are declining and falling short of goals. ICE fell from about 800 daily arrests in late January to fewer than 600 in early February.

Critics argue the administration is merely showcasing efforts with ineffectiveness, while Trump seeks billions more in funding to support his deportation agenda. Increased involvement from various federal agencies is intended to assist ICE, but many lack specific immigration training.

Challenges persist, as fewer immigrants are available for quick deportation due to a decline in illegal crossings. Local sheriffs are also pressured by rising demands to accommodate immigrants, which may strain resources further.

E-cash are coupons or tokens for Bitcoin, or Bitcoin debt notes that the mint issues. The e-cash states, essentially, "IoU 2900 sats".

They're redeemable for Bitcoin on Lightning (hard money), and therefore can be used as cash (softer money), so long as the mint has a good reputation. That means that they're less fungible than Lightning because the e-cash from one mint can be more or less valuable than the e-cash from another. If a mint is buggy, offline, or disappears, then the e-cash is unreedemable.

It also means that e-cash is more anonymous than Lightning, and that the sender and receiver's wallets don't need to be online, to transact. Nutzaps now add the possibility of parking transactions one level farther out, on a relay. The same relays that cannot keep npub profiles and follow lists consistent will now do monetary transactions.

What we then have is * a transaction on a relay that triggers * a transaction on a mint that triggers * a transaction on Lightning that triggers * a transaction on Bitcoin.

Which means that every relay that stores the nuts is part of a wildcat banking system. Which is fine, but relay operators should consider whether they wish to carry the associated risks and liabilities. They should also be aware that they should implement the appropriate features in their relay, such as expiration tags (nuts rot after 2 weeks), and to make sure that only expired nuts are deleted.

There will be plenty of specialized relays for this, so don't feel pressured to join in, and research the topic carefully, for yourself.

intro

The Russian state made me a Bitcoiner. In 1991, it devalued my grandmother's hard-earned savings. She worked tirelessly in the kitchen of a dining car on the Moscow–Warsaw route. Everything she had saved for my sister and me to attend university vanished overnight. This story is similar to what many experienced, including Wences Casares. The pain and injustice of that time became my first lessons about the fragility of systems and the value of genuine, incorruptible assets, forever changing my perception of money and my trust in government promises.

In 2014, I was living in Moscow, running a trading business, and frequently traveling to China. One day, I learned about the Cypriot banking crisis and the possibility of moving money through some strange thing called Bitcoin. At the time, I didn’t give it much thought. Returning to the idea six months later, as a business-oriented geek, I eagerly began studying the topic and soon dove into it seriously.

I spent half a year reading articles on a local online journal, BitNovosti, actively participating in discussions, and eventually joined the editorial team as a translator. That’s how I learned about whitepapers, decentralization, mining, cryptographic keys, and colored coins. About Satoshi Nakamoto, Silk Road, Mt. Gox, and BitcoinTalk. Over time, I befriended the journal’s owner and, leveraging my management experience, later became an editor. I was drawn to the crypto-anarchist stance and commitment to decentralization principles. We wrote about the economic, historical, and social preconditions for Bitcoin’s emergence, and it was during this time that I fully embraced the idea.

It got to the point where I sold my apartment and, during the market's downturn, bought 50 bitcoins, just after the peak price of $1,200 per coin. That marked the beginning of my first crypto winter. As an editor, I organized workflows, managed translators, developed a YouTube channel, and attended conferences in Russia and Ukraine. That’s how I learned about Wences Casares and even wrote a piece about him. I also met Mikhail Chobanyan (Ukrainian exchange Kuna), Alexander Ivanov (Waves project), Konstantin Lomashuk (Lido project), and, of course, Vitalik Buterin. It was a time of complete immersion, 24/7, and boundless hope.

After moving to the United States, I expected the industry to grow rapidly, attended events, but the introduction of BitLicense froze the industry for eight years. By 2017, it became clear that the industry was shifting toward gambling and creating tokens for the sake of tokens. I dismissed this idea as unsustainable. Then came a new crypto spring with the hype around beautiful NFTs – CryptoPunks and apes.

I made another attempt – we worked on a series called Digital Nomad Country Club, aimed at creating a global project. The proceeds from selling images were intended to fund the development of business tools for people worldwide. However, internal disagreements within the team prevented us from completing the project.

With Trump’s arrival in 2025, hope was reignited. I decided that it was time to create a project that society desperately needed. As someone passionate about history, I understood that destroying what exists was not the solution, but leaving everything as it was also felt unacceptable. You can’t destroy the system, as the fiery crypto-anarchist voices claimed.

With an analytical mindset (IQ 130) and a deep understanding of the freest societies, I realized what was missing—not only in Russia or the United States but globally—a Bitcoin-native system for tracking debts and financial interactions. This could return control of money to ordinary people and create horizontal connections parallel to state systems. My goal was to create, if not a Bitcoin killer app, then at least to lay its foundation.

At the inauguration event in New York, I rediscovered the Nostr project. I realized it was not only technologically simple and already quite popular but also perfectly aligned with my vision. For the past month and a half, using insights and experience gained since 2014, I’ve been working full-time on this project.

Russische Hobby-Flieger konnten mit ihrem Sportflugzeug namens "Andromeda" unter dem Radar bleiben und haben entlang der Hauptstromtrassen mit einem ukrainischen Zwiebelmesser die Stromleitungen gekappt. In einer scharfen Rechtskurve muss wohl eine Flugzeugtür aufgegangen sein und der Pass des Piloten fiel unbemerkt heraus. Die Identität der Täter konnte so schnell festgestellt werden.

Es gibt erst wieder Strom, wenn sich die Koalition der Willigen den Friedensverhandlungen für die Ukraine anschließt. Trump hat bewusst in den sonnenreichen Ländern Spanien und Portugal begonnen, das soll als Warnung für ganz Europa gelten. Frau von der Leyen hat bereits scharfen Protest eingelegt, doch Trump hat die SMS sofort gelöscht.

Selensky hat einen Cyber-Angriff auf das europäische Stromnetz gestartet. Er ist wütend, weil sich Macron in dem 15-Minuten-Gespräch mit Trump am Rande der Beerdigung des Papstes in Rom hat abwimmeln lassen. Er beendet die Strom-Blockade erst, wenn Spanien, Portugal und Frankreich Deutschland dazu zwingen, endlich Taurus zu liefern. Auf die Frage, wie Selensky das angestellt hat, soll er geantwortet haben: "Sie sehen ja, wir können es."

My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:

“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”

Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:

America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.

That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.

For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.

But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.

That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.

American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)

In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

The application of chlorine in water treatment is mainly reflected in its ability to act as a disinfectant. It can effectively kill bacteria, viruses and other microorganisms in water, thereby reducing the risk of waterborne diseases. The following is a detailed description of the application of chlorine in water treatment:

Disinfection As an effective disinfectant, chlorine is usually added to water during the water treatment process in the form of chlorine gas, chlorophyll acid or chlorine. This process is called chlorination, which ensures that pathogens in the water are effectively eliminated. Chlorine's disinfection ability comes from its strong oxidizing properties, which can destroy the cell structure of microorganisms to achieve the purpose of disinfection.

Disinfection By-products Despite the obvious benefits of chlorine in disinfection, there are also some negative effects. Chlorine disinfection may lead to the formation of disinfection by-products such as chloroform and chloroform, which may pose potential health risks in high concentrations. Therefore, when using chlorine for water treatment, the chlorine content needs to be strictly controlled to ensure the safety of the water.

Chlorine Measurement and Control Monitoring and controlling the chlorine content in the water treatment process is very critical. Total chlorine is the total amount of all forms of chlorine in water, including free residual chlorine, combined residual chlorine and other forms of chlorine such as chlorinated hydrocarbons. Available chlorine refers specifically to the part of chlorine in water that has bactericidal ability, including free residual chlorine, some combined residual chlorine (such as monochromatic and diamorphine) and chlorine dioxide. The measurement of available chlorine is crucial for evaluating the disinfection effect of water.

In summary, the application of chlorine in water treatment is mainly as a disinfectant to kill pathogens in water through its strong oxidizing properties. However, the use of chlorine also needs to be cautious to avoid the generation of harmful disinfection by-products, and other safer disinfectants such as chlorine dioxide can be selected when necessary.

You don’t talk about it much — but you’re tired. Tired of pretending you're okay. Tired of giving your best and wondering if it’s even enough. Tired of being strong for everyone else while quietly falling apart.

But here's something you might not hear often: I’m proud of you.

Not because you’ve figured everything out — but because you haven’t given up. Even with the weight on your shoulders, you're still here. Still trying. Still hoping. Still holding on.

That counts. That matters. That’s strength too.

The truth is, progress doesn’t always look like big wins. Sometimes it’s just getting out of bed. Sometimes it’s choosing peace over proving a point. Sometimes it’s breathing through the pain and saying, “I’ll try again tomorrow.”

So if no one has told you lately: You’re doing better than you think. Rest if you need to. Cry if you must. But don’t stop. Because something beautiful is growing from everything you’re surviving.

A debonair day-to-night hideaway fuses heritage charm with contemporary flair in the Penang capital of George Town...

Housed in a historic landmark on George Town’s atmospheric Lebuh Farquhar, just a stone’s throw from the iconic Eastern & Oriental Hotel, MOJO JOJO is a café and brunch spot by day, and a refined eatery come nightfall. With an effortlessly cool edge, the space has been designed by Empt Studio and combines contemporary charm with the energy of this Malaysian city.

Split into two sections, the venue caters to both hotel guests and passersby. One side offers an intimate, tailored dining experience for those seeking a respite from the buzz of outside, while the other spills out onto the street, embracing George Town’s lively buzz. The soaring ceilings create a sense of openness, further enhanced by the introduction of a mezzanine above the kitchen, maximising space without compromising on airiness.

Natural materials feature throughout with custom bamboo display systems and solid Nyatoh timber fixtures lending a rich, textural warmth. Deliberately crafted interlocking joints pay homage to traditional woodworking techniques, reinforcing both strength and authenticity. Every detail nods to meticulous craftsmanship, from the aged wood grains to the earthy material palette that echoes the heritage of its surroundings.

Lighting plays a supporting yet pivotal role, with carefully curated, softly diffused illumination accentuating the textures and forms within. The interplay of warm light and natural materials fosters an immersive, atmospheric retreat from the fast-paced city outside.

A refuge for slow mornings and, later on, offering a more cultured affair, MOJO JOJO is a debonair dining spot for the handsome Penang capital.

Hubless Wheels + Donut Motor brings manufacturing & performance benefits

Verge Next, a subsidiary of Estonia-based Verge Motorcycles, invented this Donut Motor. It's designed to drive a hubless wheel. Although once seen as something that simply looked cool in renderings, the company says the hubless arrangement brings performance and manufacturing benefits, "delivering unmatched torque and power density with minimal weight."

For one thing, there's no chain, belt or drivetrain required. Secondly, it frees the body of the bike from the task of holding the motor—everything is now contained within that rear wheel.

The company has not only incorporated the Donut Motor into their own bikes, but is now licensing the technology. Assuming it does what it says on the tin, our future streetscapes will be covered with hubless bikes, scooters and motorcycles.

Here's a closer look at a Verge bike and how its design is influenced by the motor:

Umbrel Core-lightning(以下CLNと略す)を運用するにあたり役に立ちそうなノウハウやメモを随時投稿します。

・configファイルを用意する Umbrelのアプリとして必要な設定はdocker-compose.ymlで指定されている。 それ以外の設定をしたい場合configファイルに入れると便利。 configファイルの置き場所は /home/umbrel/umbrel/app-data/core-lightning/data/lightningd ここにtouch configとでもやってファイルをつくる。 cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch config 以下内容をひな型として使ってみてください。 行頭に#があるとコメント行になります。つまり.iniフォーマット。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd/config ```

[General options]

[Bitcoin control options]

[Lightning daemon options]

[Lightning node customization options]

[Lightning channel and HTLC options]

[Payment control options]

[Networking options]

[Lightning Plugins]

[Experimental Options]

``` configに設定できる内容は以下を参照 https://lightning.readthedocs.io/lightningd-config.5.html セクションを意味する[]があるけれどもこれは私(tanakei)が意図的に見やすく区別しやすくするために付けただけ。これら行の＃は外さない。

・configの設定をCLNに反映させる appスクリプトでCLNを再起動すると反映することができる。 configを書き換えただけでは反映されない。 cd /home/umbrel/umbrel/scripts ./app restart core-lightning

・ログをファイルに出力させる

以下の場所でtouch log.txtとしてlog.txtファイルを作る。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch log.txt 次にconfigの[Lightning daemon options]セクションにlog-fileを追加する。 ```

[Lightning daemon options]

log-file=/data/.lightning/log.txt ``` ※Dockerによって/home/umbrel/umbrel/app-data/core-lightning/data/lightningd は /data/.lightning として使われている。

・addrとbind-addrの違い どちらも着信用のインターフェースとポートの設定。addrは指定したホストIPアドレス:ポート番号をノードURIに含めて公開する(node_announcementのuris)。bind-addrは公開しない。

・実験的機能のLN Offerを有効にする configの[Experimental Options]セクションに以下を追加する。 ```

[Experimental Options]

experimental-onion-messages experimental-offers ``` ※ v24.08でexperimental-onion-messageは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 ※ v21.11.1 では experimental-offersは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 もう実験扱いじゃなくなったのね...

・完全にTorでの発信オンリーにする UmbrelはなぜかCLNの発信をClearnetとTorのハイブリッドを許している。それは　always-use-proxy=true　の設定がないから。(LNDは発着信Torのみなのに) なのでこの設定をconfigに追加してCLNも発着進Torのみにする。 ```

[Networking options]

always-use-proxy=true ```

・任意のニーモニックからhsm_secretを作る CLNのhsm_secretはLNDのwallet.dbのようなもの。ノードで使う様々な鍵のマスター鍵となる。Umbrel CLNはこのhsm_secretファイルを自動生成したものを使い、これをバックアップするためのニーモニックを表示するとかそういう機能はない。自分で作って控えてあるニーモニックでhsm_secretを作ってしまえばこのファイルが壊れてもオンチェーン資金は復旧はできる。

1.CLNインストール後、dockerコンテナに入る docker exec -it core-lightning_lightningd_1 bash 2.lightning-hsmtoolコマンドを使って独自hsm_secretを作る ``` cd data/.lightning/bitcoin lightning-hsmtool generatehsm my-hsm_secret

・上記コマンドを実行するとニーモニックの言語、ニーモニック、パスフレーズの入力を催促される。 Select your language: 0) English (en) 1) Spanish (es) 2) French (fr) 3) Italian (it) 4) Japanese (jp) 5) Chinese Simplified (zhs) 6) Chinese Traditional (zht) Select [0-7]: 0　※定番の英単語なら0を入力 Introduce your BIP39 word list separated by space (at least 12 words): <ニーモニックを入力する> Warning: remember that different passphrases yield different bitcoin wallets. If left empty, no password is used (echo is disabled). Enter your passphrase: <パスフレーズを入力する>　※パスフレーズ不要ならそのままエンターキーを押す。 New hsm_secret file created at my-hsm_secret Use the encrypt command to encrypt the BIP32 seed if needed

コンテナから抜ける exit

3.appスクリプトでCLNを止めて、独自hsm_secret以外を削除 ※【重要】いままで使っていたhsm_secretを削除する。もしチャネル残高、ウォレット残高があるならチャネルを閉じて資金を退避すること。自己責任！ cd ~/umbrel/scripts/ ./app stop core-lightning

cd ~/umbrel/app-data/core-lightning/data/lightningd/bitcoin rm gossip_store hsm_secret lightningd.sqlite3 lightning-rpc mv my-hsm_secret hsm_secret 4.appスクリプトでCLNを再開する cd ~/umbrel/scripts/ ./app start core-lightning ```

【補記】 hsm_secret作成につかうニーモニックはBIP39で、LNDのAezeedと違って自分が作成されたブロック高さというものを含んでいない。新規でなくて復元して使う場合は作成されたブロック高さからブロックチェーンをrescanする必要がある。 configの１行目にrescanオプションを付けてCLNをリスタートする。 ``` // 特定のブロック高さを指定する場合はマイナス記号をつける rescan=-756000

// 現在のブロック高さから指定ブロック分さかのぼった高さからrescanする rescan=10000 ※現在の高さが760,000なら10000指定だと750,000からrescan ```

・clnrestについて core-lightningでREST APIを利用したい場合、別途c-lightning-restを用意する必要があった。v23.8から標準でclnrestというプラグインがついてくる。pythonで書かれていて、ソースからビルドした場合はビルド完了後にpip installでインストールする。elementsproject/lightningdのDockerイメージではインストール済みになっている。 (v25.02からgithubからバイナリをダウンロードしてきた場合はpip install不要になったようだ) このclnrestを使うにはcreaterunesコマンドでruneというLNDのマカロンのようなものを作成する必要がある。アプリ側でこのruneとREST APIを叩いてcore-lightningへアクセスすることになる。 自分が良く使っているLNbitsやスマホアプリZeus walletはclnrestを使う。まだclnrestに対応していないアプリもあるので留意されたし。

・Emergency recoverについて LNDのSCBのようなもの。ファイル名はemergency.recover チャネルを開くと更新される。 hsm_secretとこのファイルだけを置いてCLNを開始すると自動でこのファイルから強制クローズするための情報が読み出されてDLPで相手から強制クローズするような仕組み。この機能はv0.12から使える。

動作確認してみた所、LNDのSCBに比べるとかなり使いづらい。 1. CLNがTor発信だとチャネルパートナーと接続できない。 　Clearnet発信できても相手がTorのみノードならTor発信せざるを得ない。 　相手と通信できなければ資金回収できない。 2. 相手がLNDだとなぜか強制クローズされない。相手がCLNならできる。

つまり、自分と相手がClearnetノードでかつ相手もCLNならば Emergency recoverで強制クローズして資金回収できる。こんな条件の厳しい復旧方法がマジで役に立つのか？

v0.11以降ならばLNDのchannel.dbに相当するlightningd.sqlite3をプライマリ・セカンダリDBと冗長化できるので、セカンダリDBをNFSで保存すればUmbrelのストレージが壊れてもセカンダリDBで復旧できる。そのためemergerncy.recoverを使う必要がないと思われる。

・LN offer(BOLT#12)ついて 使いたいなら 1.publicチャネルを開く 　publicチャネルを開けばチャネルとノードの情報(channel_announcement, node_announcement)が他ノードに伝わる。送金したい相手がこの情報を元に経路探索する。 2.その後しばらく待つ CLNノードを立てたばかりだと経路探索するに十分なチャネルとノードの情報が揃ってない。せめて1日は待つ。

LNURLの場合インボイスをhttpsで取得するが、OfferはLN経由で取得する。そのためにチャネルとノードの情報が必要。privateチャネルばかりのノードはチャネル情報もそうだがノード情報も出さない。 Offerで使えるBlind pathという機能なら中間ノードIDを宛先ノードとすることが可能で、これならチャネルとノード情報を公開しなくても受けとれるのだがCLNは対応してない模様(2025年1月現在) CLNでOfferで受け取るにはチャネルとノード情報を公開する必要がある。そのためpublicチャネルを開く。公開されていれば良いのでTorでもOK。クリアネットで待ち受けは必須ではない。

・hsm_sercretとニーモニック lightning-hsmtoolを使うとニーモニックからhsm_secretを作れる。ニーモニックからシードを作ると64バイト。これはニーモニックおよびソルトにパスフレーズをPBKDF2(HMAC-SHA512を2048回)にかけると512ビット(64バイト)のシードができる。しかしhsm_secretは32バイト。CLNでは64バイトの最初の32バイトをhsm_secretとして利用しているみたい。 このhsm_secretにHMAC-SHA512をかけて512ビットとした値がウォレットのマスター鍵となる。なのでhsm_secret自体がBIP-32でいうマスターシードそのものではない。 sparrow walletにCLNのウォレットを復元したい場合は lightning-hsmtool dumponchaindescriptors --show-secrets とやってディスクリプターウォレットを出力。出力内容にマスター鍵(xprv～)があるので、これをインポートする。導出パス設定はm/0とする。sparrowが残りを補完してm/0/0/0, m/0/0/1とやってくれる。

"Degeneration" or "Вырождение" ![[photo_2025-01-29 23.23.15.jpeg]]

A once-functional object, now eroded by time and human intervention, stripped of its original purpose. Layers of presence accumulate—marks, alterations, traces of intent—until the very essence is obscured. Restoration is paradoxical: to reclaim, one must erase. Yet erasure is an impossibility, for to remove these imprints is to deny the existence of those who shaped them.

The work stands as a meditation on entropy, memory, and the irreversible dialogue between creation and decay.

@ 6be5cc06:5259daf0

A seguir, veja como instalar e configurar o Privoxy no Pop!_OS.

---

1. Instalar o Tor e o Privoxy

Abra o terminal e execute:

bash sudo apt update sudo apt install tor privoxy

Explicação:

• Tor: Roteia o tráfego pela rede Tor.
• Privoxy: Proxy avançado que intermedia a conexão entre aplicativos e o Tor.

---

2. Configurar o Privoxy

Abra o arquivo de configuração do Privoxy:

bash sudo nano /etc/privoxy/config

Navegue até a última linha (atalho: Ctrl + / depois Ctrl + V para navegar diretamente até a última linha) e insira:

bash forward-socks5 / 127.0.0.1:9050 .

Isso faz com que o Privoxy envie todo o tráfego para o Tor através da porta 9050.

Salve (CTRL + O e Enter) e feche (CTRL + X) o arquivo.

---

3. Iniciar o Tor e o Privoxy

Agora, inicie e habilite os serviços:

bash sudo systemctl start tor sudo systemctl start privoxy sudo systemctl enable tor sudo systemctl enable privoxy

Explicação:

• start: Inicia os serviços.
• enable: Faz com que iniciem automaticamente ao ligar o PC.

---

4. Configurar o Navegador Firefox

Para usar a rede Tor com o Firefox:

1. Abra o Firefox.
2. Acesse Configurações → Configurar conexão.
3. Selecione Configuração manual de proxy.
4. Configure assim:
   • Proxy HTTP: 127.0.0.1
   • Porta: 8118 (porta padrão do Privoxy)
   • Domínio SOCKS (v5): 127.0.0.1
   • Porta: 9050
5. Marque a opção "Usar este proxy também em HTTPS".
6. Clique em OK.

---

5. Verificar a Conexão com o Tor

Abra o navegador e acesse:

text https://check.torproject.org/

Se aparecer a mensagem "Congratulations. This browser is configured to use Tor.", a configuração está correta.

---

Dicas Extras

• Privoxy pode ser ajustado para bloquear anúncios e rastreadores.
• Outros aplicativos também podem ser configurados para usar o Privoxy.

@ b17fccdf:b7211155

The past 26 August, Tor introduced officially a proof-of-work (PoW) defense for onion services designed to prioritize verified network traffic as a deterrent against denial of service (DoS) attacks.

~ > This feature at the moment, is deactivate by default, so you need to follow these steps to activate this on a MiniBolt node:

• Make sure you have the latest version of Tor installed, at the time of writing this post, which is v0.4.8.6. Check your current version by typing

tor --version

Example of expected output:

Tor version 0.4.8.6. This build of Tor is covered by the GNU General Public License (https://www.gnu.org/licenses/gpl-3.0.en.html) Tor is running on Linux with Libevent 2.1.12-stable, OpenSSL 3.0.9, Zlib 1.2.13, Liblzma 5.4.1, Libzstd N/A and Glibc 2.36 as libc. Tor compiled with GCC version 12.2.0

~ > If you have v0.4.8.X, you are OK, if not, type sudo apt update && sudo apt upgrade and confirm to update.

• Basic PoW support can be checked by running this command:

tor --list-modules

Expected output:

relay: yes dirauth: yes dircache: yes pow: **yes**

~ > If you have pow: yes, you are OK

• Now go to the torrc file of your MiniBolt and add the parameter to enable PoW for each hidden service added

sudo nano /etc/tor/torrc

Example:

```

Hidden Service BTC RPC Explorer

HiddenServiceDir /var/lib/tor/hidden_service_btcrpcexplorer/ HiddenServiceVersion 3 HiddenServicePoWDefensesEnabled 1 HiddenServicePort 80 127.0.0.1:3002 ```

~ > Bitcoin Core and LND use the Tor control port to automatically create the hidden service, requiring no action from the user. We have submitted a feature request in the official GitHub repositories to explore the need for the integration of Tor's PoW defense into the automatic creation process of the hidden service. You can follow them at the following links:

• Bitcoin Core: https://github.com/lightningnetwork/lnd/issues/8002

เบื้องหลังการเปลี่ยนแปลงครั้งใหญ่ในประวัติศาสตร์ เราต้องเข้าใจปัจจัยที่เปลี่ยนแปลงตรรกะของความรุนแรง โดยเฉพาะปัจจัยเชิงมหภาค 4 ประเภทหลัก ได้แก่ ภูมิประเทศ ภูมิอากาศ จุลชีพ และเทคโนโลยี

1. ภูมิประเทศ เป็นตัวกำหนดที่สำคัญมากต่อรูปแบบของรัฐและความสามารถในการควบคุมพลเมืองโดยเฉพาะเมื่อเปรียบระหว่างสภาพภูมิประเทศทางบกและทางทะเล พื้นที่ทะเลเปิดนั้นยากต่อการผูกขาดหรือควบคุม ทำให้กฎของรัฐไม่สามารถบังคับใช้ได้อย่างมีประสิทธิภาพ ต่างจากแผ่นดิน ซึ่งส่งผลต่อการจัดวางอำนาจอย่างลึกซึ้ง เมื่อเศรษฐกิจเริ่มเคลื่อนเข้าสู่โลกไซเบอร์ซึ่งมีลักษณะคล้ายทะเลเปิดมากกว่าภาคพื้นดิน รูปแบบของการปกครองและการใช้ความรุนแรงจึงมีแนวโน้มเปลี่ยนแปลงไปอย่างมีนัยสำคัญ ประวัติศาสตร์ก็สนับสนุนมุมมองนี้ รัฐยุคแรก ๆ มักเกิดขึ้นในพื้นที่ราบลุ่มชลประทานที่ล้อมรอบด้วยทะเลทราย เช่น เมโสโปเตเมียและอียิปต์ ซึ่งทำให้ประชาชนจำเป็นต้องพึ่งพารัฐที่สามารถควบคุมแหล่งน้ำเพื่อดำรงชีวิตได้ ก่อให้เกิดระบบเผด็จการที่มั่นคง ขณะที่ภูมิประเทศที่กระจายอำนาจ เช่น กรีซโบราณ กลับเอื้อต่อการเกิดประชาธิปไตย เพราะผู้คนสามารถพึ่งตนเองได้มากกว่า มีอิสระในการค้าขายทางทะเล และเข้าถึงรายได้ที่นำไปแลกกับอำนาจทางทหารและการเมืองได้
2. ภูมิอากาศก็มีบทบาทไม่แพ้กันในการกำหนดกรอบของอำนาจทางการเมือง เช่น หลังสิ้นยุคน้ำแข็งราว 13,000 ปีก่อน ความเปลี่ยนแปลงของระบบนิเวศทำให้ทุ่งหญ้าเลี้ยงสัตว์ลดลง และป่าทึบเข้ามาแทนที่ ทำให้มนุษย์ต้องเปลี่ยนวิถีชีวิตจากนักล่ามาเป็นเกษตรกรอย่างหลีกเลี่ยงไม่ได้ การเปลี่ยนแปลงนี้ไม่ได้เกิดขึ้นเพราะความสมัครใจ แต่เพราะสิ่งแวดล้อมบีบบังคับ ภูมิอากาศยังมีอิทธิพลต่อเสถียรภาพทางเศรษฐกิจและการเมืองอย่างชัดเจน เช่น ศตวรรษที่ 17 ซึ่งเป็นยุคหนาวเย็นที่สุดช่วงหนึ่งในประวัติศาสตร์ ทำให้เกิดวิกฤตอาหารและความอดอยากทั่วโลก นำไปสู่การก่อกบฏและการปฏิวัติในหลายประเทศ
3. จุลชีพ ก็มีบทบาทในเชิงการเมืองมหภาคอย่างลึกซึ้ง การล่มสลายของประชากรพื้นเมืองในทวีปอเมริกาจากโรคที่ชาวยุโรปนำเข้า เช่น หัด หรือไข้ทรพิษ ทำให้ยุโรปสามารถยึดครองดินแดนเหล่านั้นได้อย่างง่ายดาย แม้ในบางครั้งจะยังไม่ได้ลงจากเรือด้วยซ้ำ ในอีกด้านหนึ่ง จุลชีพก็เคยเป็นกำแพงที่ป้องกันไม่ให้จักรวรรดิยุโรปขยายอำนาจ เช่น มาลาเรียในแอฟริกาที่เคยทำให้พื้นที่เหล่านั้น “ต่อต้านอำนาจจากภายนอก” ได้อย่างนานหลายศตวรรษ
4. เทคโนโลยี ซึ่งเป็นปัจจัยที่ที่ทรงอิทธิพลที่สุดต่อการเปลี่ยนแปลงของโครงสร้างอำนาจในประวัติศาสตร์มนุษย์ เพราะมันสามารถเปลี่ยน “ต้นทุน” และ “ผลตอบแทน” ของการใช้ความรุนแรงได้อย่างรวดเร็วและชัดเจน ทั้งในแง่ของอาณาเขต ขนาดของรัฐ ลักษณะของสงคราม และแม้แต่ความชอบธรรมทางการเมือง ผู้เขียนได้แยกอิทธิพลของเทคโนโลยีออกเป็น 5 มิติหลัก ซึ่งล้วนมีบทบาทอย่างสำคัญในการจัดรูปแบบของอำนาจ ได้แก่:

A. ดุลยภาพระหว่างการโจมตีและการป้องกัน เทคโนโลยีแต่ละยุคมีผลอย่างมากต่อความได้เปรียบระหว่างฝ่ายรุกกับฝ่ายรับ หากเทคโนโลยีในยุคนั้นเอื้อต่อ “การโจมตี” (เช่น เครื่องยิงหิน, รถถัง, ระเบิดทางอากาศ) ต้นทุนของการขยายอำนาจจะต่ำลง รัฐหรือจักรวรรดิจะรวมศูนย์มากขึ้นเพราะสามารถควบคุมพื้นที่กว้างได้ด้วยกำลังที่มีประสิทธิภาพ แต่หากเทคโนโลยีเอื้อให้ “การป้องกัน” มีต้นทุนต่ำและได้เปรียบ (เช่น ปราสาทยุคกลาง, อาวุธต่อต้านอากาศยาน, การเข้ารหัสข้อมูลในโลกไซเบอร์) รัฐจะมีแนวโน้มกระจายตัว และอำนาจท้องถิ่นจะแข็งแกร่งขึ้น

B. ความเท่าเทียมกันทางทหารของพลเมือง เทคโนโลยีอาวุธยังเป็นตัวแปรสำคัญในการกำหนดว่า “พลเมืองธรรมดา” มีอำนาจเพียงใดในการเผชิญหน้ากับชนชั้นปกครอง ตัวอย่างที่ชัดเจนคือในยุคก่อนปฏิวัติดินปืน ชาวนาที่ถือแค่ส้อมหรือจอบไม่อาจต้านอัศวินติดเกราะได้ แต่เมื่อการใช้ปืนแพร่หลาย เส้นแบ่งระหว่างสามัญชนกับขุนนางก็เริ่มจางลง และเกิดการปฏิวัติทางสังคมตามมาในหลายพื้นที่

C. ขนาดขององค์กรที่จำเป็นต่อการใช้ความรุนแรง บางเทคโนโลยีต้องการระบบสนับสนุนขนาดใหญ่ เช่น เสบียง การสื่อสาร การขนส่ง และระบบการฝึกฝนที่ซับซ้อน ซึ่งหมายความว่าเฉพาะองค์กรที่มีทรัพยากรขนาดใหญ่เท่านั้นจึงสามารถใช้อำนาจอย่างมีประสิทธิภาพได้ ตัวอย่างเช่น สมัยสงครามโลก รัฐที่มีอุตสาหกรรมและสายส่งที่มั่นคงเท่านั้นจึงสามารถรบได้นาน

D. ขนาดของกิจกรรมทางเศรษฐกิจในการผลิต ขนาดของหน่วยเศรษฐกิจที่ “เหมาะสมที่สุด” ในการผลิตสินค้าและบริการก็เป็นตัวแปรทางเทคโนโลยีที่ส่งผลต่อโครงสร้างของรัฐ หากเศรษฐกิจจำเป็นต้องอาศัยตลาดขนาดใหญ่ พื้นที่กว้าง หรือระบบโลจิสติกส์ที่ซับซ้อน รัฐขนาดใหญ่จะมีข้อได้เปรียบ เช่น จักรวรรดิอังกฤษที่สามารถจัดระบบเศรษฐกิจข้ามทวีปได้ในศตวรรษที่ 19 แต่หากเทคโนโลยีเอื้อให้เศรษฐกิจท้องถิ่นมีความคล่องตัว สามารถผลิตแบบกระจาย (distributed production)ได้ รัฐขนาดใหญ่ก็จะมีประสิทธิภาพน้อยลง และอำนาจจะกระจายตัว

E. การกระจายของเทคโนโลยี หากเทคโนโลยีสามารถถูก “ผูกขาด” ได้โดยกลุ่มเล็ก ๆ เช่น การควบคุมแหล่งพลังงานนิวเคลียร์ หรือการพัฒนาอาวุธล้ำสมัย อำนาจจะกระจุกอยู่กับชนชั้นนำ แต่หากเทคโนโลยีแพร่กระจายได้อย่างกว้างขวาง เช่น การใช้ดินปืน แป้นพิมพ์ อำนาจก็จะสลายตัวไปยังประชาชนทั่วไป

เมื่อพิจารณาประวัติศาสตร์ในมุมของ “สิ่งที่เกิดขึ้นจริง” ควบคู่กับ “สิ่งที่อาจเกิดขึ้นได้” เราจะเริ่มตระหนักถึงบทบาทของโอกาสและความเปราะบางที่มักถูกมองข้าม โดยเฉพาะในกรณีของจุลชีพ แม้จะเป็นตัวแปรที่ทรงพลังในอดีต แต่กลับดูเหมือนว่ามันมีผลกระทบต่อโครงสร้างอำนาจในยุคใหม่ต่ำกว่าที่ควรจะเป็น ทั้งที่ในทางทฤษฎีแล้ว มันมีศักยภาพสูงยิ่งในการเปลี่ยนแปลงประวัติศาสตร์ หากเชื้อไวรัสสายพันธุ์ใหม่ที่ร้ายแรงและแพร่กระจายได้ง่าย เทียบเท่าหรือรุนแรงกว่ามาลาเรีย แพร่ระบาดในหมู่นักสำรวจโปรตุเกสช่วงต้นของยุคการเดินเรือ อาจไม่มีการสำรวจหรือขยายอาณานิคมเกิดขึ้นเลย เช่นเดียวกับหากโคลัมบัสและผู้ย้ายถิ่นกลุ่มแรกในโลกใหม่ต้องเผชิญโรคร้ายที่มีฤทธิ์รุนแรงพอ ๆ กับหัดซึ่งคร่าชีวิตชาวพื้นเมืองไปอย่างมหาศาล พวกเขาอาจไม่สามารถตั้งรกรากได้เลยด้วยซ้ำ

แต่เมื่อมองย้อนกลับไป สิ่งเหล่านี้กลับไม่เคยเกิดขึ้น และนั่นทำให้เรายิ่งมีแนวโน้มจะเชื่อใน “ชะตากรรม” บางอย่างของประวัติศาสตร์ อย่างไรก็ตาม หากมองในแง่กลไกของพลังที่ขับเคลื่อนอำนาจ การที่จุลชีพกลับมีบทบาทสนับสนุนการรวมศูนย์ของรัฐในยุคใหม่มากกว่าการขัดขวาง ก็เป็นสิ่งที่น่าพิจารณา ทหารและผู้ตั้งถิ่นฐานจากโลกตะวันตกไม่ได้มีเพียงเทคโนโลยีเป็นแต้มต่อ แต่ยังมี “ภูมิคุ้มกันที่สั่งสมจากประสบการณ์กับโรค” อีกด้วย โรคที่มาพร้อมกับนักสำรวจจากยุโรปจึงกลายเป็น “อาวุธลับ” ที่ทำลายชาวพื้นเมืองก่อนที่ผู้รุกรานจะลงจากเรือด้วยซ้ำ

แม้ว่าจะมีข้อสันนิษฐานว่าซิฟิลิสแพร่จากโลกใหม่กลับไปยังยุโรป แต่ผลกระทบของมันก็จำกัดอยู่ในระดับวัฒนธรรม โดยเฉพาะด้านศีลธรรมทางเพศ ไม่ได้ส่งผลกระทบในระดับการเมืองมหภาคอย่างที่โรคระบาดในยุคกลางเคยทำ เช่น กาฬโรคหรือโรคไข้ทรพิษ เพราะในยุคสมัยใหม่ ระบบอุตสาหกรรมและโครงสร้างทางการแพทย์มีความสามารถในการควบคุมภัยจากจุลชีพได้มากขึ้น ไม่ว่าจะผ่านระบบสุขาภิบาล วัคซีน หรือยาปฏิชีวนะ

อย่างไรก็ดี การปรากฏตัวของโรคเอดส์ และความกังวลเกี่ยวกับไวรัสกลายพันธุ์ในช่วงปลายศตวรรษที่ 20 ได้แสดงให้เห็นว่า จุลชีพอาจไม่ได้เป็น “ปัจจัยรอง” ที่ไร้ฤทธิ์เสมอไป และอาจหวนกลับมาเป็นปัจจัยหลักที่กำหนดแนวทางของอำนาจใหม่อีกครั้งได้ในอนาคต หากมีโรคระบาดใหญ่เกิดขึ้นซึ่งรุนแรงพอที่จะทำลายความสามารถของรัฐในการควบคุมระบบเศรษฐกิจและชีวิตสาธารณะ โครงสร้างของอำนาจอาจสั่นคลอนยิ่งกว่าผลกระทบจากภูมิอากาศหรือภูมิประเทศเสียอีก

ปัญหาคือเราไม่สามารถคาดการณ์จุดเริ่มต้นของเหตุการณ์เหล่านี้ได้อย่างแม่นยำ ไม่มีแบบจำลองใดที่สามารถควบคุมหรือคาดเดาธรรมชาติได้อย่างสมบูรณ์ แม้จะมีความพยายามทางวิทยาศาสตร์และการเฝ้าระวังระดับโลก การที่เรารอดพ้นจากโรคร้ายในอดีตไม่ได้แปลว่าจะรอดได้อีกในอนาคต ความคาดหวังว่าปัจจัยมหภาคในพันปีข้างหน้าจะยังคงเป็น “เทคโนโลยี” ไม่ใช่ “จุลชีพ” จึงเป็นเพียงสมมติฐานที่ตั้งอยู่บนความหวังมากกว่าหลักประกันใด ๆ

และแม้ว่าเทคโนโลยีจะมีบทบาทอย่างล้นเหลือในช่วงห้าศตวรรษที่ผ่านมา แต่บทเรียนจากการปฏิวัติการเกษตรในยุคโบราณก็ยังคงเตือนใจว่า ปัจจัยที่เปลี่ยนแปลงวิถีของอำนาจในระดับรากฐานที่สุดอาจไม่ได้ยิ่งใหญ่หรือก้าวหน้าเสมอไป บางครั้งสิ่งที่ทำให้โลกเปลี่ยนแปลงไปอย่างถาวร ไม่ใช่จักรกลที่ซับซ้อนหรืออาวุธล้ำยุค หากแต่เป็นสิ่งมีชีวิตขนาดเล็กที่เราแทบมองไม่เห็นด้วยตาเปล่า — และมันก็อาจย้อนกลับมามีบทบาทสำคัญอีกครั้งในศตวรรษของเรา.

อย่าลืมว่าหนังสือเล่มนี้เขียนขึ้นในปี 1997 — ยุคที่โลกยังไม่เคยรู้จักกับ COVID-19

บทถัดไปจะพูดถึงเรื่องการปฏิวัติครั้งแรกของ Sapiens การปฏิวัติเกษตรกรรม

PAN... แค่แพนเค้ก หรือ แผนล้อมโลกเรื่องอาหาร เมื่อหมากตัวจริงชื่อ Sebastian Joy

เราได้รู้จักกับคุณ Sebastian Joy กันไปแล้วนะครับ วันนี้เรามาขยายผลกันอีกหน่อย

ถ้าโลกนี้เป็นเกมหมากรุก อาหารคือกระดานที่ทุกตัวหมากต้องเหยียบเดิน และใครที่วางหมากอาหารได้...ก็วางโลกได้เหมือนกัน

ปี 2018 มีโครงการหนึ่งถือกำเนิดขึ้นในเยอรมนีอย่างเงียบๆ ชื่อว่า Physicians Association for Nutrition (PAN) เบื้องหน้าเหมือนเป็นมูลนิธิการกุศล ตั้งขึ้นมาเพื่อ "ช่วยให้หมอเข้าใจเรื่องโภชนาการจากพืช" แต่ถ้าเปิดแว่นขยายส่องให้ดีๆ มันคือหนึ่งในฟันเฟืองสำคัญของแผนเปลี่ยนอนาคตอาหารโลกจาก Animal-Based ไปเป็น Plant-Based ที่เป็น lab plant based ที่ไม่ใช่อาหารธรรมชาติแบบหลักแก่นที่ Vegan สืบทอดกันมา โดยอ้างเรื่อง "สุขภาพ" และ "สิ่งแวดล้อม" เป็นฉากหน้า

PAN นั้นเสมือนเป็นลูกสมุนตัวกลั่นของคนที่ชื่อ Sebastian Joy ชายหนุ่มสายโปรโมทแนว Vegan ที่ก่อนหน้านั้นก่อตั้งองค์กร ProVeg International ซึ่งมีสายสัมพันธ์กับพวก Start-up อาหารทางเลือก (ไม่ว่าจะเป็นเนื้อปลอม เนื้อพืชดีเอนเอ นมพืชที่มาจากจุลินทรีย์ ไปจนถึงการส่งเสริมวัตถุดิบจากแบคทีเรีย โรงงาน และห้องแลบ) แล้ว ProVeg ไม่ได้ทำงานเดี่ยวๆ นะจ๊ะ... เบื้องหลังเชื่อมโยงกับเครือข่ายที่หนุน World Economic Forum (WEF) และแนวคิด Great Reset ที่อยาก "รีเซ็ต" วิธีการกินของคนทั้งโลก โดยให้อาหารเป็น Plant-Based แบบ lab created และ Meat Lab-Based เป็นหลัก

ส่วน PAN ถูกใช้เป็น "หมากที่แต่งตัวเป็นหมอ" เพื่อเดินเกมไปสู่การแทรกแซงนโยบายประเทศต่างๆ ผ่านช่องทาง "สาธารณสุข" และ "การศึกษาแพทย์" เพื่อมาเป็นกำลังหลักให้ในแผนงาน

เรามาดูตัวอย่างผลงานเด่นของ PAN กันครับ 1. ผลักดันให้รวม Plant-Based เข้าไปในหลักสูตรแพทย์และพยาบาล (โดยใช้เหตุผลว่า "หมอต้องรู้จักอาหารเพื่อสุขภาพ") 2. ช่วยรณรงค์ให้โรงพยาบาล โรงเรียน และมหาวิทยาลัย เปลี่ยนเมนูอาหารเป็น Plant-Based 3. สนับสนุนงานวิจัย และโครงการ เช่น Green Food Experience ที่กดดันให้ภาคธุรกิจและภาครัฐบาลหันมาทำตาม "แนวทางอาหารยั่งยืน" แบบที่ PAN และพรรคพวกกำหนด 4. มีสถานะ "Observer" ในองค์การสหประชาชาติ (UN) เพื่อเสนอความคิดเห็นในการกำหนดนโยบายสาธารณสุขและสิ่งแวดล้อมระดับโลก

และเบื้องหลังอีกชั้นที่น่าสนใจ... Sebastian Joy มีความสัมพันธ์ลึกซึ้งกับวงการ Start-up อาหารใหม่ๆ ที่พยายามตีตลาด Plant-Based และ Lab-Grown Food อย่างเช่น Perfect Day, Beyond Meat, Mosa Meat ฯลฯ ผ่านการโปรโมท "โภชนาการจากพืชเพื่อสุขภาพที่ดีกว่า" โดยใช้ PAN เป็นเครื่องมือให้ดู "มีอำนาจทางวิชาการ" มากขึ้น

หรือถ้าให้พูดง่ายๆ คือ สร้างสนามแข่ง แล้วจับมือกับนักแข่งที่ตัวเองลงทุนไว้ PAN ดูเหมือนเป็นองค์กรกลางๆ ใสๆ แต่มันเชื่อมโยงกับโครงข่าย NGO และบริษัทเอกชนที่มุ่งแปลงร่างอาหารโลกอยู่เบื้องหลัง การที่ PAN ผลักดันนโยบายระดับประเทศ และแทรกซึมในระบบการศึกษา หมายความว่าอนาคตคนรุ่นใหม่จะถูกปลูกฝังแนวคิด "เนื้อสัตว์ไม่ดี" โดยไม่ทันรู้ตัว

แล้วมันเกี่ยวอะไรกับเรา? จินตนาการดูครับว่า - ถ้าวันหนึ่งโรงเรียนของลูกเรามีแต่เมนูถั่วเหลือง ซีเรียล นมโอ๊ต หรือ ไอศกรีมเวย์จากจุลินทรีย์ และห้ามเสิร์ฟเนื้อสัตว์ด้วยสารพัดเหตุผล เช่น เนื้อปนเปื้อนง่าย เนื้อทำให้เป็นมะเร็ง หรือแม้แต่สอนเด็กว่า เนื้อคือตัวการทำลายสิ่งแวดล้อมด้วย มีเทน นั่นอาจเป็นผลลัพธ์จากงานเบื้องหลังของ PAN - ถ้าวันหนึ่งนโยบายอาหารของประเทศเน้นลดเนื้อสัตว์ อ้างสุขภาพ อ้างสิ่งแวดล้อม อ้างโรคระบาด อ้างกฎแห่ง DNA ที่ถูกจดสิทธิบัตร แล้วโปรโมทเนื้อปลอมแทน นั่นอาจเป็นรอยเท้าของ Sebastian Joy ที่เดินมาก่อนแล้ว - ถ้าวันหนึ่งหมอจำนวนมากเชื่อว่า “เนื้อสัตว์คือตัวร้ายที่แพร่มะเร็งหรือทำให้สุขภาพเสีย” โดยไม่มีการตั้งคำถาม นั่นคือชัยชนะของหมากตัวนี้

ในขณะที่คนส่วนใหญ่คิดว่ากำลังเลือกอาหารเอง หรือ คิดว่าฉันกิน plant base / vegan เพราะรักโลก รักสุขภาพ แต่จริงๆ แล้วมีมือที่มองไม่เห็นกำหนด "ตัวเลือก" ไว้แล้วเรียบร้อย เพราะทั้งหมดมันไม่ได้เป็นอาหารธรรมชาติ มันคืออาหาร "สร้าง" ที่ไม่มีสัตว์, มันคืออาหาร "สร้าง" ที่ต้อง "สร้าง" มาจากโรงงาน แล้วเราต้อง "ซื้อ" มากินเท่านั้น ถ้าไม่สร้าง local ให้แข็งแรง อย่าหลงไปตามความสวยงามของการรักโลกในมุมเดียว เราอาจจะไม่สามารถปลูกพืชมาเป็นอาหารเองได้ เราอาจไม่สามารถเลี้ยงสัตว์เพื่อกินเองได้

PAN ไม่ใช่แค่องค์กรให้ความรู้ด้านโภชนาการ / PAN คือเครื่องมือในกระดานหมากรุกที่กำลังจัดการ "ตั้งโปรแกรมใหม่" ให้คนทั้งโลกกินตามแบบที่นายทุนและเครือข่ายเบื้องหลังเขียนบทไว้ และชายที่ชื่อ Sebastian Joy นี่แหละ...คือหนึ่งในผู้ถือหมากที่ยิ้มอยู่หลังม่าน

อาหารแห่งอนาคต มีทางเดินเหลือไว้ให้ เกษตรกร old school บ้างไหม สนธิสัญญาต่างๆเรื่องเมล็ดพันธุ์ เหลือทางเดินไว้ให้เกษตรกรบ้างไหม หรือสุดท้าย เราจะไม่มีไดเอทให้เลือก ให้ทะเลาะกัน เพราะสุดท้าย เราต่างต้องกินอาหารจากโรงงานเหมือนกันหมด บทความนี้คงจะเป็นได้แค่เพียง การตั้งคำถามขึ้นมาไว้ แต่ไม่มีคำตอบ ว่าเรากำลังโดนอ้าง plant based food มาเคลือบความเป็น อาหารโรงงาน (Plant Food) หรือเปล่าเพราะวันนี้หลายคนอาจมองว่าเป็นการตื่นตูม คิดมาก หรือแม้แต่ เราเลือกได้แหละ ก็ได้ครับ

ผมไม่ได้มีปัญหากับสายพืชล้วน ไม่ว่าจะเจ วีแกน แพลนท์เบส เพราะถ้ากินเป็น มองสารอาหารเป็น จัดการ anti nutrient ได้ดี มันก็ดีสำหรับคนนั้น แต่ซีรีส์นี้สำคัญที่ว่า plant based food is not PLANT food อาหารจากพืชไม่ใช่อาหารจากโรงงานครับ

ก่อนถึงวันที่เราจะไม่มีสิทธิ์แม้แต่จะเลือก #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.

Satoshi Nakamoto

Resumo

O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.

As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.

Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.

---

1. Introdução

Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.

Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.

Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.

O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.

Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.

2. Transações

Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.

O que é uma assinatura digital?

Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.

Como funciona na prática?

Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:

1. A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
2. Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
3. Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.

Resolvendo o problema do gasto duplo

Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.

O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.

Por que isso é importante?

Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.

---

3. Servidor Timestamp

Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.

Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.

Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.

Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.

O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.

---

4. Prova-de-Trabalho

Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.

A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.

Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.

A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.

Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.

---

5. Rede

A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:

1. Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.

2. Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).

3. Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.

4. Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.

5. Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.

6. Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.

Resolução de Conflitos e Escolha da Cadeia Mais Longa

Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.

Tolerância a Falhas

A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.

Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.

---

6. Incentivo

O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.

Recompensa por Mineração

Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.

Taxas de Transação

Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.

Incentivo à Honestidade

O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:

1. Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
2. Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.

A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.

Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.

7. Recuperação do Espaço em Disco

Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.

Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.

Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.

Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.

---

8. Verificação de Pagamento Simplificada

É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.

Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.

A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.

Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.

---

9. Combinando e Dividindo Valor

No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.

Entradas e Saídas

Cada transação no Bitcoin é composta por:

• Entradas: Representam os valores recebidos em transações anteriores.
• Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.

Normalmente, uma transação contém:

• Uma única entrada com valor suficiente para cobrir o pagamento.
• Ou várias entradas combinadas para atingir o valor necessário.

O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.

Exemplo Prático

Imagine que você tem duas entradas:

1. 0,03 BTC
2. 0,07 BTC

Se deseja enviar 0,08 BTC para alguém, a transação terá:

• Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
• Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).

Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.

Difusão e Simplificação

A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.

---

10. Privacidade

O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.

Fluxo de Informação

• No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
• No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.

Protegendo a Privacidade

Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:

1. Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
2. Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.

Riscos de Ligação

Embora a privacidade seja fortalecida, alguns riscos permanecem:

• Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
• O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.

---

11. Cálculos

Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.

Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.

Mas isso é extremamente difícil.

Como o Ataque Funciona

Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.

• Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
• O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.

Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.

A Corrida Entre Cadeias

Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.

Suponha que:

• A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
• O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).

Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.

Por Que o Ataque Fica Cada Vez Mais Improvável?

Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:

P = (q/p)^z

• q é o poder computacional do atacante (20%, ou 0,2).
• p é o poder computacional da rede honesta (80%, ou 0,8).
• z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.

Se o atacante está 5 blocos atrás (z = 5):

P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)

Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.

Se ele estiver 10 blocos atrás (z = 10):

P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).

Neste caso, as chances de sucesso são praticamente nulas.

Um Exemplo Simples

Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.

No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.

Por Que Tudo Isso é Seguro?

• A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
• A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.

E Se o Atacante Tentar Continuar?

O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.

Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.

---

12. Conclusão

Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

Os princípios básicos da criptografia.

Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.

Criptografia e descriptografia.

Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.

https://image.nostr.build/0e2fcb71ed86a6083e083abbb683f8c103f44a6c6db1aeb2df10ae51ec97ebe5.jpg

Figura 1-1. Criptografia e descriptografia

O que é criptografia?

Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.

Criptografia forte.

"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.

Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.

Como funciona a criptografia?

Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.

Criptografia convencional.

Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg

Figura 1-2. Criptografia convencional

Cifra de César.

Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.

Gerenciamento de chaves e criptografia convencional.

A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?

Criptografia de chave pública.

Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.

[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg

Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).

Como funciona o PGP.

O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.

Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.

Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para

problemas de distribuição de chaves e transmissão de dados. Usados ​​em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.

Chaves.

Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados ​​para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.

Assinaturas digitais.

Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.

Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.

Figura 1-6. Assinaturas digitais simples

Funções hash.

O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ​​ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.

Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.

Certificados digitais.

Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.

Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados ​​para impedir tentativas de substituir a chave de uma pessoa por outra.

Um certificado digital consiste em três coisas:

● Uma chave pública.

● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.

O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável. Figura 1-8. Anatomia de um certificado PGP

Distribuição de certificados.

Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).

Servidores de certificados.

Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.

Infraestruturas de Chave Pública.

Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).

Formatos de certificado.

Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.

O PGP reconhece dois formatos de certificado diferentes:

● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).

● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.) Figura 1-9. Um certificado PGP

Formato de certificado X.509.

X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados ​​por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)

Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:

O número da versão X.509

— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.

A chave pública do titular do certificado

— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.

O número de série do certificado

— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.

O identificador exclusivo do detentor do certificado

— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)

O período de validade do certificado

— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.

O nome exclusivo do emissor do certificado

— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)

A assinatura digital do emitente

— a assinatura utilizando a chave privada da entidade que emitiu o certificado.

O identificador do algoritmo de assinatura

— identifica o algoritmo usado pela CA para assinar o certificado.

Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;

● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação

● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave

● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave

Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.

Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.

Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.

Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.

Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.

Verificando validade.

Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .

Estabelecendo confiança.

Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.

Introdutores meta e confiáveis.

​​Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.

Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis ​​podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.

Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis ​​são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.

Modelos de confiança.

Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:

Confiança Direta.

Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis ​​porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta. Figura 1-11. Confiança direta

Confiança Hierárquica.

Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.

Figura 1-12. Confiança hierárquica

Teia de Confiança.

Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.

Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.

Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de

● se o usuário considera ou não uma chave específica válida

● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros

Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.

Níveis de confiança no PGP.

O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.

Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:

● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)

Para tornar as coisas confusas, também existem três níveis de validade:

● Válido ● Marginalmente válido ● Inválido

Para definir a chave de outra pessoa como um introdutor confiável, você

1. Comece com uma chave válida, que seja.
2. assinado por você ou

3. assinado por outro apresentador confiável e então

4. Defina o nível de confiança que você acha que o proprietário da chave tem direito.

Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis ​​para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.

Revogação de certificado.

Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.

Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)

Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.

Comunicar que um certificado foi revogado.

Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.

O que é uma senha?

A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.

Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?

PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.

Divisão de chave.

Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

The recent shutdown of TikTok in the United States due to a potential government ban serves as a stark reminder how fragile centralized platforms truly are under the surface. While these platforms offer convenience, a more polished user experience, and connectivity, they are ultimately beholden to governments, corporations, and other authorities. This makes them vulnerable to censorship, regulation, and outright bans. In contrast, Nostr represents a shift in how we approach online communication and content sharing. Built on the principles of decentralization and user choice, Nostr cannot be banned, because it is not a platform—it is a protocol.

PROTOCOLS, NOT PLATFORMS.

At the heart of Nostr's philosophy is user choice, a feature that fundamentally sets it apart from legacy platforms. In centralized systems, the user experience is dictated by a single person or governing entity. If the platform decides to filter, censor, or ban specific users or content, individuals are left with little action to rectify the situation. They must either accept the changes or abandon the platform entirely, often at the cost of losing their social connections, their data, and their identity.

What's happening with TikTok could never happen on Nostr. With Nostr, the dynamics are completely different. Because it is a protocol, not a platform, no single entity controls the ecosystem. Instead, the protocol enables a network of applications and relays that users can freely choose from. If a particular application or relay implements policies that a user disagrees with, such as censorship, filtering, or even government enforced banning, they are not trapped or abandoned. They have the freedom to move to another application or relay with minimal effort.

THIS IS POWERFUL.

Take, for example, the case of a relay that decides to censor specific content. On a legacy platform, this would result in frustration and a loss of access for users. On Nostr, however, users can simply connect to a different relay that does not impose such restrictions. Similarly, if an application introduces features or policies that users dislike, they can migrate to a different application that better suits their preferences, all while retaining their identity and social connections.

The same principles apply to government bans and censorship. A government can ban a specific application or even multiple applications, just as it can block one relay or several relays. China has implemented both tactics, yet Chinese users continue to exist and actively participate on Nostr, demonstrating Nostr's ability to resistant censorship.

How? Simply, it turns into a game of whack-a-mole. When one relay is censored, another quickly takes its place. When one application is banned, another emerges. Users can also bypass these obstacles by running their own relays and applications directly from their homes or personal devices, eliminating reliance on larger entities or organizations and ensuring continuous access.

AGAIN, THIS IS POWERUFL.

Nostr's open and decentralized design makes it resistant to the kinds of government intervention that led to TikTok's outages this weekend and potential future ban in the next 90 days. There is no central server to target, no company to regulate, and no single point of failure. (Insert your CEO jokes here). As long as there are individuals running relays and applications, users continue creating notes and sending zaps.

Platforms like TikTok can be silenced with the stroke of a pen, leaving millions of users disconnected and abandoned. Social communication should not be silenced so incredibly easily. No one should have that much power over social interactions.

Will we on-board a massive wave of TikTokers in the coming hours or days? I don't know.

TikTokers may not be ready for Nostr yet, and honestly, Nostr may not be ready for them either. The ecosystem still lacks the completely polished applications, tools, and services they’re accustomed to. This is where we say "we're still early". They may not be early adopters like the current Nostr user base. Until we bridge that gap, they’ll likely move to the next centralized platform, only to face another government ban or round of censorship in the future. But eventually, there will come a tipping point, a moment when they’ve had enough. When that time comes, I hope we’re prepared. If we’re not, we risk missing a tremendous opportunity to onboard people who genuinely need Nostr’s freedom.

Until then, to all of the Nostr developers out there, keep up the great work and keep building. Your hard work and determination is needed.

Einleitung\ \ Schwierige Dinge einfach zu erklären ist der Anspruch von ELI5 (explain me like I'm 5). Das ist in unserer hoch technisierten Welt dringend erforderlich, denn nur mit dem Verständnis der Technologien können wir sie richtig einsetzen und weiter entwickeln.\ Ich starte meine Serie mit Nostr, einem relativ neuen Internet-Protokoll. Was zum Teufel ist ein Internet-Protokoll? Formal beschrieben sind es internationale Standards, die dafür sorgen, dass das Internet seit über 30 Jahren ziemlich gut funktioniert. Es ist die Sprache, in der sich die Rechner miteinander unterhalten und die auch Sie täglich nutzen, vermutlich ohne es bewusst wahrzunehmen. http(s) transportiert ihre Anfrage an einen Server (z.B. Amazon), und html sorgt dafür, dass aus den gelieferten Daten eine schöne Seite auf ihrem Bildschirm entsteht. Eine Mail wird mit smtp an den Mailserver gesendet und mit imap von ihm abgerufen, und da alle den Standard verwenden, funktioniert das mit jeder App auf jedem Betriebssystem und mit jedem Mail-Provider. Und mit einer Mail-Adresse wie roland@pareto.space können sie sogar jederzeit umziehen, egal wohin. Cool, das ist state of the art! Aber warum funktioniert das z.B. bei Chat nicht, gibt es da kein Protokoll? Doch, es heißt IRC (Internet Relay Chat → merken sie sich den Namen), aber es wird so gut wie nicht verwendet. Die Gründe dafür sind nicht technischer Natur, vielmehr wurden mit Apps wie Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok u.a. bewusst Inkompatibilitäten und Nutzerabhängigkeiten geschaffen um Profite zu maximieren.

Warum Nostr?

Da das Standard-Protokoll nicht genutzt wird, hat jede App ihr eigenes, und wir brauchen eine handvoll Apps um uns mit allen Bekannten auszutauschen. Eine Mobilfunknummer ist Voraussetzung für jedes Konto, damit können die App-Hersteller die Nutzer umfassend tracken und mit dem Verkauf der Informationen bis zu 30 USD je Konto und Monat verdienen. Der Nutzer ist nicht mehr Kunde, er ist das Produkt! Der Werbe-SPAM ist noch das kleinste Problem bei diesem Geschäftsmodell. Server mit Millionen von Nutzerdaten sind ein “honey pot”, dementsprechend oft werden sie gehackt und die Zugangsdaten verkauft. 2024 wurde auch der Twitter-Account vom damaligen Präsidenten Joe Biden gehackt, niemand wusste mehr wer die Nachrichten verfasst hat (vorher auch nicht), d.h. die Authentizität der Inhalte ist bei keinem dieser Anbieter gewährleistet. Im selben Jahr wurde der Telegram-Gründer in Frankreich in Beugehaft genommen, weil er sich geweigert hatte Hintertüren in seine Software einzubauen. Nun kann zum Schutz "unserer Demokratie” praktisch jeder mitlesen, was sie mit wem an Informationen austauschen, z.B. darüber welches Shampoo bestimmte Politiker verwenden. 

Und wer tatsächlich glaubt er könne Meinungsfreiheit auf sozialen Medien praktizieren, findet sich schnell in der Situation von Donald Trump wieder (seinerzeit amtierender Präsident), dem sein Twitter-Konto 2021 abgeschaltet wurde (Cancel-Culture). Die Nutzerdaten, also ihr Profil, ihre Kontakte, Dokumente, Bilder, Videos und Audiofiles - gehören ihnen ohnehin nicht mehr sondern sind Eigentum des Plattform-Betreibers; lesen sie sich mal die AGB's durch. Aber nein, keine gute Idee, das sind hunderte Seiten und sie werden permanent geändert. Alle nutzen also Apps, deren Technik sie nicht verstehen, deren Regeln sie nicht kennen, wo sie keine Rechte haben und die ihnen die Resultate ihres Handelns stehlen. Was würde wohl der Fünfjährige sagen, wenn ihm seine ältere Schwester anbieten würde, alle seine Spielzeuge zu “verwalten” und dann auszuhändigen wenn er brav ist? “Du spinnst wohl”, und damit beweist der Knirps mehr Vernunft als die Mehrzahl der Erwachsenen. \ \ Resümee: keine Standards, keine Daten, keine Rechte = keine Zukunft!

\ Wie funktioniert Nostr?

Die Entwickler von Nostr haben erkannt dass sich das Server-Client-Konzept in ein Master-Slave-Konzept verwandelt hatte. Der Master ist ein Synonym für Zentralisierung und wird zum “single point of failure”, der zwangsläufig Systeme dysfunktional macht. In einem verteilten Peer2Peer-System gibt es keine Master mehr sondern nur gleichberechtigte Knoten (Relays), auf denen die Informationen gespeichert werden. Indem man Informationen auf mehreren Relays redundant speichert, ist das System in jeglicher Hinsicht resilienter. Nicht nur die Natur verwendet dieses Prinzip seit Jahrmillionen erfolgreich, auch das Internet wurde so konzipiert (das ARPAnet wurde vom US-Militär für den Einsatz in Kriegsfällen unter massiven Störungen entwickelt). Alle Nostr-Daten liegen auf Relays und der Nutzer kann wählen zwischen öffentlichen (zumeist kostenlosen) und privaten Relays, z.B. für geschlossene Gruppen oder zum Zwecke von Daten-Archivierung. Da Dokumente auf mehreren Relays gespeichert sind, werden statt URL's (Locator) eindeutige Dokumentnamen (URI's = Identifier) verwendet, broken Links sind damit Vergangenheit und Löschungen / Verluste ebenfalls.\ \ Jedes Dokument (Event genannt) wird vom Besitzer signiert, es ist damit authentisch und fälschungssicher und kann nur vom Ersteller gelöscht werden. Dafür wird ein Schlüsselpaar verwendet bestehend aus privatem (nsec) und öffentlichem Schlüssel (npub) wie aus der Mailverschlüsselung (PGP) bekannt. Das repräsentiert eine Nostr-Identität, die um Bild, Namen, Bio und eine lesbare Nostr-Adresse ergänzt werden kann (z.B. roland@pareto.space ), mehr braucht es nicht um alle Ressourcen des Nostr-Ökosystems zu nutzen. Und das besteht inzwischen aus über hundert Apps mit unterschiedlichen Fokussierungen, z.B. für persönliche verschlüsselte Nachrichten (DM → OxChat), Kurznachrichten (Damus, Primal), Blogbeiträge (Pareto), Meetups (Joinstr), Gruppen (Groups), Bilder (Olas), Videos (Amethyst), Audio-Chat (Nostr Nests), Audio-Streams (Tunestr), Video-Streams (Zap.Stream), Marktplätze (Shopstr) u.v.a.m. Die Anmeldung erfolgt mit einem Klick (single sign on) und den Apps stehen ALLE Nutzerdaten zur Verfügung (Profil, Daten, Kontakte, Social Graph → Follower, Bookmarks, Comments, etc.), im Gegensatz zu den fragmentierten Datensilos der Gegenwart.\ \ Resümee: ein offener Standard, alle Daten, alle Rechte = große Zukunft!

\ Warum ist Nostr die Zukunft des Internet?

“Baue Dein Haus nicht auf einem fremden Grundstück” gilt auch im Internet - für alle App-Entwickler, Künstler, Journalisten und Nutzer, denn auch ihre Daten sind werthaltig. Nostr garantiert das Eigentum an den Daten, und überwindet ihre Fragmentierung. Weder die Nutzung noch die kreativen Freiheiten werden durch maßlose Lizenz- und Nutzungsbedingungen eingeschränkt. Aus passiven Nutzern werden durch Interaktion aktive Teilnehmer, Co-Creatoren in einer Sharing-Ökonomie (Value4Value). OpenSource schafft endlich wieder Vertrauen in die Software und ihre Anbieter. Offene Standards ermöglichen den Entwicklern mehr Kooperation und schnellere Entwicklung, für die Anwender garantieren sie Wahlfreiheit. Womit wir letztmalig zu unserem Fünfjährigen zurückkehren. Kinder lieben Lego über alles, am meisten die Maxi-Box “Classic”, weil sie damit ihre Phantasie im Kombinieren voll ausleben können. Erwachsene schenken ihnen dann die viel zu teuren Themenpakete, mit denen man nur eine Lösung nach Anleitung bauen kann. “Was stimmt nur mit meinen Eltern nicht, wann sind die denn falsch abgebogen?" fragt sich der Nachwuchs zu Recht. Das Image lässt sich aber wieder aufpolieren, wenn sie ihren Kindern Nostr zeigen, denn die Vorteile verstehen sogar Fünfjährige.

\ Das neue Internet ist dezentral. Das neue Internet ist selbstbestimmt. Nostr ist das neue Internet.

Bitcoin is more than money, more than an asset, and more than a store of value. Bitcoin is a Prime Mover, an enabler and it ignites imaginations. It certainly fueled an idea in my mind. The idea integrates sensors, computational prowess, actuated machinery, power conversion, and electronic communications to form an autonomous, machined creature roaming forests and harvesting the most widespread and least energy-dense fuel source available. I call it the Forest Walker and it eats wood, and mines Bitcoin.

I know what you're thinking. Why not just put Bitcoin mining rigs where they belong: in a hosted facility sporting electricity from energy-dense fuels like natural gas, climate-controlled with excellent data piping in and out? Why go to all the trouble building a robot that digests wood creating flammable gasses fueling an engine to run a generator powering Bitcoin miners? It's all about synergy.

Bitcoin mining enables the realization of multiple, seemingly unrelated, yet useful activities. Activities considered un-profitable if not for Bitcoin as the Prime Mover. This is much more than simply mining the greatest asset ever conceived by humankind. It’s about the power of synergy, which Bitcoin plays only one of many roles. The synergy created by this system can stabilize forests' fire ecology while generating multiple income streams. That’s the realistic goal here and requires a brief history of American Forest management before continuing.

Smokey The Bear

In 1944, the Smokey Bear Wildfire Prevention Campaign began in the United States. “Only YOU can prevent forest fires” remains the refrain of the Ad Council’s longest running campaign. The Ad Council is a U.S. non-profit set up by the American Association of Advertising Agencies and the Association of National Advertisers in 1942. It would seem that the U.S. Department of the Interior was concerned about pesky forest fires and wanted them to stop. So, alongside a national policy of extreme fire suppression they enlisted the entire U.S. population to get onboard via the Ad Council and it worked. Forest fires were almost obliterated and everyone was happy, right? Wrong.

Smokey is a fantastically successful bear so forest fires became so few for so long that the fuel load - dead wood - in forests has become very heavy. So heavy that when a fire happens (and they always happen) it destroys everything in its path because the more fuel there is the hotter that fire becomes. Trees, bushes, shrubs, and all other plant life cannot escape destruction (not to mention homes and businesses). The soil microbiology doesn’t escape either as it is burned away even in deeper soils. To add insult to injury, hydrophobic waxy residues condense on the soil surface, forcing water to travel over the ground rather than through it eroding forest soils. Good job, Smokey. Well done, Sir!

Most terrestrial ecologies are “fire ecologies”. Fire is a part of these systems’ fuel load and pest management. Before we pretended to “manage” millions of acres of forest, fires raged over the world, rarely damaging forests. The fuel load was always too light to generate fires hot enough to moonscape mountainsides. Fires simply burned off the minor amounts of fuel accumulated since the fire before. The lighter heat, smoke, and other combustion gasses suppressed pests, keeping them in check and the smoke condensed into a plant growth accelerant called wood vinegar, not a waxy cap on the soil. These fires also cleared out weak undergrowth, cycled minerals, and thinned the forest canopy, allowing sunlight to penetrate to the forest floor. Without a fire’s heat, many pine tree species can’t sow their seed. The heat is required to open the cones (the seed bearing structure) of Spruce, Cypress, Sequoia, Jack Pine, Lodgepole Pine and many more. Without fire forests can’t have babies. The idea was to protect the forests, and it isn't working.

So, in a world of fire, what does an ally look like and what does it do?

Meet The Forest Walker

For the Forest Walker to work as a mobile, autonomous unit, a solid platform that can carry several hundred pounds is required. It so happens this chassis already exists but shelved.

Introducing the Legged Squad Support System (LS3). A joint project between Boston Dynamics, DARPA, and the United States Marine Corps, the quadrupedal robot is the size of a cow, can carry 400 pounds (180 kg) of equipment, negotiate challenging terrain, and operate for 24 hours before needing to refuel. Yes, it had an engine. Abandoned in 2015, the thing was too noisy for military deployment and maintenance "under fire" is never a high-quality idea. However, we can rebuild it to act as a platform for the Forest Walker; albeit with serious alterations. It would need to be bigger, probably. Carry more weight? Definitely. Maybe replace structural metal with carbon fiber and redesign much as 3D printable parts for more effective maintenance.

The original system has a top operational speed of 8 miles per hour. For our purposes, it only needs to move about as fast as a grazing ruminant. Without the hammering vibrations of galloping into battle, shocks of exploding mortars, and drunken soldiers playing "Wrangler of Steel Machines", time between failures should be much longer and the overall energy consumption much lower. The LS3 is a solid platform to build upon. Now it just needs to be pulled out of the mothballs, and completely refitted with outboard equipment.

The Small Branch Chipper

When I say “Forest fuel load” I mean the dead, carbon containing litter on the forest floor. Duff (leaves), fine-woody debris (small branches), and coarse woody debris (logs) are the fuel that feeds forest fires. Walk through any forest in the United States today and you will see quite a lot of these materials. Too much, as I have described. Some of these fuel loads can be 8 tons per acre in pine and hardwood forests and up to 16 tons per acre at active logging sites. That’s some big wood and the more that collects, the more combustible danger to the forest it represents. It also provides a technically unlimited fuel supply for the Forest Walker system.

The problem is that this detritus has to be chewed into pieces that are easily ingestible by the system for the gasification process (we’ll get to that step in a minute). What we need is a wood chipper attached to the chassis (the LS3); its “mouth”.

A small wood chipper handling material up to 2.5 - 3.0 inches (6.3 - 7.6 cm) in diameter would eliminate a substantial amount of fuel. There is no reason for Forest Walker to remove fallen trees. It wouldn’t have to in order to make a real difference. It need only identify appropriately sized branches and grab them. Once loaded into the chipper’s intake hopper for further processing, the beast can immediately look for more “food”. This is essentially kindling that would help ignite larger logs. If it’s all consumed by Forest Walker, then it’s not present to promote an aggravated conflagration.

I have glossed over an obvious question: How does Forest Walker see and identify branches and such? LiDaR (Light Detection and Ranging) attached to Forest Walker images the local area and feed those data to onboard computers for processing. Maybe AI plays a role. Maybe simple machine learning can do the trick. One thing is for certain: being able to identify a stick and cause robotic appendages to pick it up is not impossible.

Great! We now have a quadrupedal robot autonomously identifying and “eating” dead branches and other light, combustible materials. Whilst strolling through the forest, depleting future fires of combustibles, Forest Walker has already performed a major function of this system: making the forest safer. It's time to convert this low-density fuel into a high-density fuel Forest Walker can leverage. Enter the gasification process.

The Gassifier

The gasifier is the heart of the entire system; it’s where low-density fuel becomes the high-density fuel that powers the entire system. Biochar and wood vinegar are process wastes and I’ll discuss why both are powerful soil amendments in a moment, but first, what’s gasification?

Reacting shredded carbonaceous material at high temperatures in a low or no oxygen environment converts the biomass into biochar, wood vinegar, heat, and Synthesis Gas (Syngas). Syngas consists primarily of hydrogen, carbon monoxide, and methane. All of which are extremely useful fuels in a gaseous state. Part of this gas is used to heat the input biomass and keep the reaction temperature constant while the internal combustion engine that drives the generator to produce electrical power consumes the rest.

Critically, this gasification process is “continuous feed”. Forest Walker must intake biomass from the chipper, process it to fuel, and dump the waste (CO2, heat, biochar, and wood vinegar) continuously. It cannot stop. Everything about this system depends upon this continual grazing, digestion, and excretion of wastes just as a ruminal does. And, like a ruminant, all waste products enhance the local environment.

When I first heard of gasification, I didn’t believe that it was real. Running an electric generator from burning wood seemed more akin to “conspiracy fantasy” than science. Not only is gasification real, it’s ancient technology. A man named Dean Clayton first started experiments on gasification in 1699 and in 1901 gasification was used to power a vehicle. By the end of World War II, there were 500,000 Syngas powered vehicles in Germany alone because of fossil fuel rationing during the war. The global gasification market was $480 billion in 2022 and projected to be as much as $700 billion by 2030 (Vantage Market Research). Gasification technology is the best choice to power the Forest Walker because it’s self-contained and we want its waste products.

Biochar: The Waste

Biochar (AKA agricultural charcoal) is fairly simple: it’s almost pure, solid carbon that resembles charcoal. Its porous nature packs large surface areas into small, 3 dimensional nuggets. Devoid of most other chemistry, like hydrocarbons (methane) and ash (minerals), biochar is extremely lightweight. Do not confuse it with the charcoal you buy for your grill. Biochar doesn’t make good grilling charcoal because it would burn too rapidly as it does not contain the multitude of flammable components that charcoal does. Biochar has several other good use cases. Water filtration, water retention, nutrient retention, providing habitat for microscopic soil organisms, and carbon sequestration are the main ones that we are concerned with here.

Carbon has an amazing ability to adsorb (substances stick to and accumulate on the surface of an object) manifold chemistries. Water, nutrients, and pollutants tightly bind to carbon in this format. So, biochar makes a respectable filter and acts as a “battery” of water and nutrients in soils. Biochar adsorbs and holds on to seven times its weight in water. Soil containing biochar is more drought resilient than soil without it. Adsorbed nutrients, tightly sequestered alongside water, get released only as plants need them. Plants must excrete protons (H+) from their roots to disgorge water or positively charged nutrients from the biochar's surface; it's an active process.

Biochar’s surface area (where adsorption happens) can be 500 square meters per gram or more. That is 10% larger than an official NBA basketball court for every gram of biochar. Biochar’s abundant surface area builds protective habitats for soil microbes like fungi and bacteria and many are critical for the health and productivity of the soil itself.

The “carbon sequestration” component of biochar comes into play where “carbon credits” are concerned. There is a financial market for carbon. Not leveraging that market for revenue is foolish. I am climate agnostic. All I care about is that once solid carbon is inside the soil, it will stay there for thousands of years, imparting drought resiliency, fertility collection, nutrient buffering, and release for that time span. I simply want as much solid carbon in the soil because of the undeniably positive effects it has, regardless of any climactic considerations.

Wood Vinegar: More Waste

Another by-product of the gasification process is wood vinegar (Pyroligneous acid). If you have ever seen Liquid Smoke in the grocery store, then you have seen wood vinegar. Principally composed of acetic acid, acetone, and methanol wood vinegar also contains ~200 other organic compounds. It would seem intuitive that condensed, liquefied wood smoke would at least be bad for the health of all living things if not downright carcinogenic. The counter intuition wins the day, however. Wood vinegar has been used by humans for a very long time to promote digestion, bowel, and liver health; combat diarrhea and vomiting; calm peptic ulcers and regulate cholesterol levels; and a host of other benefits.

For centuries humans have annually burned off hundreds of thousands of square miles of pasture, grassland, forest, and every other conceivable terrestrial ecosystem. Why is this done? After every burn, one thing becomes obvious: the almost supernatural growth these ecosystems exhibit after the burn. How? Wood vinegar is a component of this growth. Even in open burns, smoke condenses and infiltrates the soil. That is when wood vinegar shows its quality.

This stuff beefs up not only general plant growth but seed germination as well and possesses many other qualities that are beneficial to plants. It’s a pesticide, fungicide, promotes beneficial soil microorganisms, enhances nutrient uptake, and imparts disease resistance. I am barely touching a long list of attributes here, but you want wood vinegar in your soil (alongside biochar because it adsorbs wood vinegar as well).

The Internal Combustion Engine

Conversion of grazed forage to chemical, then mechanical, and then electrical energy completes the cycle. The ICE (Internal Combustion Engine) converts the gaseous fuel output from the gasifier to mechanical energy, heat, water vapor, and CO2. It’s the mechanical energy of a rotating drive shaft that we want. That rotation drives the electric generator, which is the heartbeat we need to bring this monster to life. Luckily for us, combined internal combustion engine and generator packages are ubiquitous, delivering a defined energy output given a constant fuel input. It’s the simplest part of the system.

The obvious question here is whether the amount of syngas provided by the gasification process will provide enough energy to generate enough electrons to run the entire system or not. While I have no doubt the energy produced will run Forest Walker's main systems the question is really about the electrons left over. Will it be enough to run the Bitcoin mining aspect of the system? Everything is a budget.

CO2 Production For Growth

Plants are lollipops. No matter if it’s a tree or a bush or a shrubbery, the entire thing is mostly sugar in various formats but mostly long chain carbohydrates like lignin and cellulose. Plants need three things to make sugar: CO2, H2O and light. In a forest, where tree densities can be quite high, CO2 availability becomes a limiting growth factor. It’d be in the forest interests to have more available CO2 providing for various sugar formation providing the organism with food and structure.

An odd thing about tree leaves, the openings that allow gasses like the ever searched for CO2 are on the bottom of the leaf (these are called stomata). Not many stomata are topside. This suggests that trees and bushes have evolved to find gasses like CO2 from below, not above and this further suggests CO2 might be in higher concentrations nearer the soil.

The soil life (bacterial, fungi etc.) is constantly producing enormous amounts of CO2 and it would stay in the soil forever (eventually killing the very soil life that produces it) if not for tidal forces. Water is everywhere and whether in pools, lakes, oceans or distributed in “moist” soils water moves towards to the moon. The water in the soil and also in the water tables below the soil rise toward the surface every day. When the water rises, it expels the accumulated gasses in the soil into the atmosphere and it’s mostly CO2. It’s a good bet on how leaves developed high populations of stomata on the underside of leaves. As the water relaxes (the tide goes out) it sucks oxygenated air back into the soil to continue the functions of soil life respiration. The soil “breathes” albeit slowly.

The gasses produced by the Forest Walker’s internal combustion engine consist primarily of CO2 and H2O. Combusting sugars produce the same gasses that are needed to construct the sugars because the universe is funny like that. The Forest Walker is constantly laying down these critical construction elements right where the trees need them: close to the ground to be gobbled up by the trees.

The Branch Drones

During the last ice age, giant mammals populated North America - forests and otherwise. Mastodons, woolly mammoths, rhinos, short-faced bears, steppe bison, caribou, musk ox, giant beavers, camels, gigantic ground-dwelling sloths, glyptodons, and dire wolves were everywhere. Many were ten to fifteen feet tall. As they crashed through forests, they would effectively cleave off dead side-branches of trees, halting the spread of a ground-based fire migrating into the tree crown ("laddering") which is a death knell for a forest.

These animals are all extinct now and forests no longer have any manner of pruning services. But, if we build drones fitted with cutting implements like saws and loppers, optical cameras and AI trained to discern dead branches from living ones, these drones could effectively take over pruning services by identifying, cutting, and dropping to the forest floor, dead branches. The dropped branches simply get collected by the Forest Walker as part of its continual mission.

The drones dock on the back of the Forest Walker to recharge their batteries when low. The whole scene would look like a grazing cow with some flies bothering it. This activity breaks the link between a relatively cool ground based fire and the tree crowns and is a vital element in forest fire control.

The Bitcoin Miner

Mining is one of four monetary incentive models, making this system a possibility for development. The other three are US Dept. of the Interior, township, county, and electrical utility company easement contracts for fuel load management, global carbon credits trading, and data set sales. All the above depends on obvious questions getting answered. I will list some obvious ones, but this is not an engineering document and is not the place for spreadsheets. How much Bitcoin one Forest Walker can mine depends on everything else. What amount of biomass can we process? Will that biomass flow enough Syngas to keep the lights on? Can the chassis support enough mining ASICs and supporting infrastructure? What does that weigh and will it affect field performance? How much power can the AC generator produce?

Other questions that are more philosophical persist. Even if a single Forest Walker can only mine scant amounts of BTC per day, that pales to how much fuel material it can process into biochar. We are talking about millions upon millions of forested acres in need of fuel load management. What can a single Forest Walker do? I am not thinking in singular terms. The Forest Walker must operate as a fleet. What could 50 do? 500?

What is it worth providing a service to the world by managing forest fuel loads? Providing proof of work to the global monetary system? Seeding soil with drought and nutrient resilience by the excretion, over time, of carbon by the ton? What did the last forest fire cost?

The Mesh Network

What could be better than one bitcoin mining, carbon sequestering, forest fire squelching, soil amending behemoth? Thousands of them, but then they would need to be able to talk to each other to coordinate position, data handling, etc. Fitted with a mesh networking device, like goTenna or Meshtastic LoRa equipment enables each Forest Walker to communicate with each other.

Now we have an interconnected fleet of Forest Walkers relaying data to each other and more importantly, aggregating all of that to the last link in the chain for uplink. Well, at least Bitcoin mining data. Since block data is lightweight, transmission of these data via mesh networking in fairly close quartered environs is more than doable. So, how does data transmit to the Bitcoin Network? How do the Forest Walkers get the previous block data necessary to execute on mining?

Back To The Chain

Getting Bitcoin block data to and from the network is the last puzzle piece. The standing presumption here is that wherever a Forest Walker fleet is operating, it is NOT within cell tower range. We further presume that the nearest Walmart Wi-Fi is hours away. Enter the Blockstream Satellite or something like it.

A separate, ground-based drone will have two jobs: To stay as close to the nearest Forest Walker as it can and to provide an antennae for either terrestrial or orbital data uplink. Bitcoin-centric data is transmitted to the "uplink drone" via the mesh networked transmitters and then sent on to the uplink and the whole flow goes in the opposite direction as well; many to one and one to many.

We cannot transmit data to the Blockstream satellite, and it will be up to Blockstream and companies like it to provide uplink capabilities in the future and I don't doubt they will. Starlink you say? What’s stopping that company from filtering out block data? Nothing because it’s Starlink’s system and they could decide to censor these data. It seems we may have a problem sending and receiving Bitcoin data in back country environs.

But, then again, the utility of this system in staunching the fuel load that creates forest fires is extremely useful around forested communities and many have fiber, Wi-Fi and cell towers. These communities could be a welcoming ground zero for first deployments of the Forest Walker system by the home and business owners seeking fire repression. In the best way, Bitcoin subsidizes the safety of the communities.

Sensor Packages

LiDaR

The benefit of having a Forest Walker fleet strolling through the forest is the never ending opportunity for data gathering. A plethora of deployable sensors gathering hyper-accurate data on everything from temperature to topography is yet another revenue generator. Data is valuable and the Forest Walker could generate data sales to various government entities and private concerns.

LiDaR (Light Detection and Ranging) can map topography, perform biomass assessment, comparative soil erosion analysis, etc. It so happens that the Forest Walker’s ability to “see,” to navigate about its surroundings, is LiDaR driven and since it’s already being used, we can get double duty by harvesting that data for later use. By using a laser to send out light pulses and measuring the time it takes for the reflection of those pulses to return, very detailed data sets incrementally build up. Eventually, as enough data about a certain area becomes available, the data becomes useful and valuable.

Forestry concerns, both private and public, often use LiDaR to build 3D models of tree stands to assess the amount of harvest-able lumber in entire sections of forest. Consulting companies offering these services charge anywhere from several hundred to several thousand dollars per square kilometer for such services. A Forest Walker generating such assessments on the fly while performing its other functions is a multi-disciplinary approach to revenue generation.

pH, Soil Moisture, and Cation Exchange Sensing

The Forest Walker is quadrupedal, so there are four contact points to the soil. Why not get a pH data point for every step it takes? We can also gather soil moisture data and cation exchange capacities at unheard of densities because of sampling occurring on the fly during commission of the system’s other duties. No one is going to build a machine to do pH testing of vast tracts of forest soils, but that doesn’t make the data collected from such an endeavor valueless. Since the Forest Walker serves many functions at once, a multitude of data products can add to the return on investment component.

Weather Data

Temperature, humidity, pressure, and even data like evapotranspiration gathered at high densities on broad acre scales have untold value and because the sensors are lightweight and don’t require large power budgets, they come along for the ride at little cost. But, just like the old mantra, “gas, grass, or ass, nobody rides for free”, these sensors provide potential revenue benefits just by them being present.

I’ve touched on just a few data genres here. In fact, the question for universities, governmental bodies, and other institutions becomes, “How much will you pay us to attach your sensor payload to the Forest Walker?”

Noise Suppression

Only you can prevent Metallica filling the surrounds with 120 dB of sound. Easy enough, just turn the car stereo off. But what of a fleet of 50 Forest Walkers operating in the backcountry or near a township? 500? 5000? Each one has a wood chipper, an internal combustion engine, hydraulic pumps, actuators, and more cooling fans than you can shake a stick at. It’s a walking, screaming fire-breathing dragon operating continuously, day and night, twenty-four hours a day, three hundred sixty-five days a year. The sound will negatively affect all living things and that impacts behaviors. Serious engineering consideration and prowess must deliver a silencing blow to the major issue of noise.

It would be foolish to think that a fleet of Forest Walkers could be silent, but if not a major design consideration, then the entire idea is dead on arrival. Townships would not allow them to operate even if they solved the problem of widespread fuel load and neither would governmental entities, and rightly so. Nothing, not man nor beast, would want to be subjected to an eternal, infernal scream even if it were to end within days as the fleet moved further away after consuming what it could. Noise and heat are the only real pollutants of this system; taking noise seriously from the beginning is paramount.

Fire Safety

A “fire-breathing dragon” is not the worst description of the Forest Walker. It eats wood, combusts it at very high temperatures and excretes carbon; and it does so in an extremely flammable environment. Bad mix for one Forest Walker, worse for many. One must take extreme pains to ensure that during normal operation, a Forest Walker could fall over, walk through tinder dry brush, or get pounded into the ground by a meteorite from Krypton and it wouldn’t destroy epic swaths of trees and baby deer. I envision an ultimate test of a prototype to include dowsing it in grain alcohol while it’s wrapped up in toilet paper like a pledge at a fraternity party. If it runs for 72 hours and doesn’t set everything on fire, then maybe outside entities won’t be fearful of something that walks around forests with a constant fire in its belly.

The Wrap

How we think about what can be done with and adjacent to Bitcoin is at least as important as Bitcoin’s economic standing itself. For those who will tell me that this entire idea is without merit, I say, “OK, fine. You can come up with something, too.” What can we plug Bitcoin into that, like a battery, makes something that does not work, work? That’s the lesson I get from this entire exercise. No one was ever going to hire teams of humans to go out and "clean the forest". There's no money in that. The data collection and sales from such an endeavor might provide revenues over the break-even point but investment demands Alpha in this day and age. But, plug Bitcoin into an almost viable system and, voilà! We tip the scales to achieve lift-off.

Let’s face it, we haven’t scratched the surface of Bitcoin’s forcing function on our minds. Not because it’s Bitcoin, but because of what that invention means. The question that pushes me to approach things this way is, “what can we create that one system’s waste is another system’s feedstock?” The Forest Walker system’s only real waste is the conversion of low entropy energy (wood and syngas) into high entropy energy (heat and noise). All other output is beneficial to humanity.

Bitcoin, I believe, is the first product of a new mode of human imagination. An imagination newly forged over the past few millennia of being lied to, stolen from, distracted and otherwise mis-allocated to a black hole of the nonsensical. We are waking up.

What I have presented is not science fiction. Everything I have described here is well within the realm of possibility. The question is one of viability, at least in terms of the detritus of the old world we find ourselves departing from. This system would take a non-trivial amount of time and resources to develop. I think the system would garner extensive long-term contracts from those who have the most to lose from wildfires, the most to gain from hyperaccurate data sets, and, of course, securing the most precious asset in the world. Many may not see it that way, for they seek Alpha and are therefore blind to other possibilities. Others will see only the possibilities; of thinking in a new way, of looking at things differently, and dreaming of what comes next.

Die baldige Ex-Außenministerin Annalena Baerbock fordert einen radikalen Wandel in der Energieversorgung hin zu einer feministischen Energiepolitik. Wie sich gezeigt habe, so sei das spanische Netz am 28.04.25 wegen toxischer Männlichkeit zusammengebrochen. Es hätte sich herausgestellt, dass alle Überlandleitungen von Männern gebaut und installiert worden waren! Dies, so Baerbock, sei ein untragbarer Zustand, der durch den resultierenden Blackout für viel Leid und Ärger gesorgt habe. Selbst Haarföhns waren nicht mehr in Betrieb zu nehmen!

«Nur Frauen sind in der Lage, derart empfindliche und sensible Ströme zu leiten. Denn Strömen liegt in ihrer Natur. Sie benötigen keine Messgeräte oder teure Transformatoren für die Strömung, da Mutter Natur – eine Frau, wie der Name schon sagt – für alles selbst sorgen wird. Man muss nur verhindern, dass maskuline Energien verströmt werden, die nämlich den Strom um 360 Grad drehen würden.»

Mit dieser Analyse empfiehlt sich Annalena B. nicht nur für höchste UN Ämter sondern ebenfalls für den Vorsitz des Weltklimarates IPCC. Aus informierten Kreisen ist zu hören, dass sie nur noch die Papstwahl abwarten möchte - schließlich wäre es Zeit für eine Päpstin - bis sie sich fürs Klima bewerben würde. Um weitere Blackouts abzuschrecken überlegt sie angeblich, ihren Namen in Blackbock zu ändern. Möglich wäre allerdings auch, dass dies alles nur erfunden ist.

@ f1f59549:f4121cfe

Ego is a fundamental part of the human condition. It provides us with the necessary ability to separate and compartmentalize ourselves from the rest of the world.

Our ego allows us to exist in the chaos of existence.

The spiritual path is seen as a way to “escape the ego” and achieve a higher state of consciousness. A state where the confines of the ego no longer hold us back from seeing things as they are and allow us to experience true bliss.

But there’s a paradox to this whole process.

By seeking spiritual advancement, we have to accept that there is something to improve and someone to do the improving.

This suggests that this improvement somehow makes us better than someone who has not achieved similar levels of improvement.

This kind of thinking is inherently egotistical.

As we advance down the spiritual path — escaping the grasp of ego and removing attachments — spirituality itself can end up feeding the ego. Most of the time, we don’t even notice it while it’s happening.

It’s an unconscious process that develops along the way. Only after we notice it within ourselves can we course-correct.

I acknowledge that writing this article is itself an example of spiritual egotism.

Who am I to talk about dissolving the ego? What are my goals for writing this piece? By pointing out the hypocrisy behind having spiritual convictions or goals, am I in some way suggesting myself to be free from these convictions?

I am in no way exempt from the clutches of spiritual egotism — I certainly have not reached enlightenment.

But the paradox is that if I had, I probably wouldn’t be talking about it now.

This is known in Buddhism as the “noble silence.”

The only way to understand what it truly means to “dissolve the ego” is by discovering it spontaneously. It is not something that can be taught.

This is the approach Zen Buddhism takes to reach enlightenment. By accepting that the truth cannot be told, the master does not try to speak it. Instead, the master simply pops the ego of his students as it bubbles up from time to time.

This employs a concept called “the middle way.”

You know that you must dissolve your ego. But you can’t, so trying it is also pointless. The middle way says, “I will do my best to escape my ego, but I accept that I will fail.”

One thing we can do is pay attention to our failings. When you perform a kind act for another person, consider the motivation behind why you did it. Was it for their sake or for yours?

If you’re able to convince yourself these acts come from selfless motives — take notice — your ego has just presented itself.

The Paradox of Spiritual Development

You want to improve yourself by changing your consciousness. But the self that needs to be improved is the same one doing the improving.

This is a paradox.

As egotistical beings, we cannot be without ego.

At its core, the very reason one seeks to dissolve the ego is to improve oneself. Whether it’s to feel well, perform more effectively, or improve relationships with others — the very desire to achieve this improvement is egotistical.

This forms a negative feedback loop. The more we attempt to remove the ego, the more egotistical we become.

Essentially, the harder we try to avoid it, the more we become it.

By choosing to take a path toward enlightenment — we can not reach enlightenment.

The great Alan Watts says it best (paraphrasing):

“As long as you think and feel that you are contained in your bag of skin, there is no way whatsoever to behave unselfishly. You can imitate unselfishness. Undergo all kinds of highly refined forms of unselfishness. But you’re still tied to the gold chains of your good deeds.”

Is There A Solution?

Not exactly, but we may be able to move closer toward enlightenment by accepting its impossibility. Simply allowing ourselves to notice this paradox in ourselves may allow us to redirect course toward the middle path once again.

Let’s look at the story of the Buddha as an example.

Siddhartha was an ascetic for several decades. Acetics of the time would do all sorts of austere techniques. He would starve himself, sleep out in the cold, and purposely subject himself to discomfort and hardship — all an attempt to dissociate from his physical body and, thus, his ego.

The goal was to “reach” enlightenment.

But all the attempts the Buddha made to get himself out of the trap failed.

Siddhartha only achieved enlightenment when he realized that the trap and the trapped are one. By this realization, there isn’t any trap left.

He realized that the spiritual journey isn’t about being on some sort of “higher level.” There is no “end goal” or plateau to reach.

The spiritual teacher Eckhart Tolle puts it another way:

“The ego has many ideas. It says, ‘I want to be a spiritual person. I want to be recognized as a spiritual person. I want to be more spiritual than all these people. And I’m definitely more spiritual than you… The essential dysfunction of the ego is still operating. This is why we have the phrase ‘the road to hell is paved with good intentions’… You have to reach the place within yourself that is unconditioned; that is what I sometimes call formless.”

Spiritual Arrogance is a Blind Spot on the Path to Enlightenment

Spirituality can help you release the firm grasp your ego has over you, but it can also reinforce it.

Spiritual arrogance arises when someone develops an identity about seeking a path to enlightenment. It’s sometimes referred to as “spiritual narcissism.”

It’s what happens when you feel like people just “aren’t quite on your level.”

“High vibrations,” right?

As the psychiatrist Gerald May wrote in his 1983 book Will and Spirit:

“Simply stated, spiritual narcissism is the unconscious use of spiritual practice, experience, and insight to increase rather than decrease self-importance.”

Spiritual arrogance emerges naturally as we engage on the spiritual path. We fool ourselves into thinking that by taking steps to become more “enlightened,” we’re in some way superior to those who do not.

We leverage spiritual practices — like yoga, meditation, or other forms of spiritual self-care — as tokens of our supposed enlightenment or moral superiority.

We may use our "spiritual" identity to look down upon others who don't share these practices or beliefs, to dodge personal responsibilities or interpersonal challenges, or to create a persona that earns us social capital.

This condition damages both the individual, who is missing the opportunity for genuine spiritual or personal growth, and the community around them, which may be subjected to their judgment, manipulation, or neglect.

The presentation of spiritual arrogance comes in all shapes and sizes.

Let’s say you join a church group or other spiritual group. Members become spiritually proud. They believe they are the ones who have the right teaching. Everybody else is a bit off the track.

Then someone comes and one-ups them. “In our circles, we’re very tolerant. And we accept all teachings and all ways as leading to the one.”

But they’re just playing the game of “we’re more tolerant than you are.”

In essence, they become a victim of their own spiritual practice — they’re blind to the paradox of the spiritual path and become lost in their own egotistical beliefs that their “way” is somehow better than everybody else’s.

Of course, the other side of this paradox comes from noticing the people around you who demonstrate signs of spiritual arrogance. Looking at someone in their arrogance can make you feel like they’re inferior.

It’s another trap — but it comes from the completely opposite angle.

We cannot escape it.

Can Spiritual Arrogance Be Avoided?

Probably not, but by learning to recognize it, we may be able to re-align ourselves towards the middle path when it inevitably appears over and over again throughout our lives.

Here are some ideas to think about for avoiding the paradoxical nature of spiritual arrogance:

1. Find your intuitive expertise & learn to flow with it

Taoists call this practice “wu-wei.” Zen Buddhists call it “mushin.” Both loosely refer to an absence of striving. It’s the constant striving to improve or reach “higher vibrations” that causes this paradox to manifest in a big way.

2. Stop judging others based on their “level”

Spirituality is not a competition; you are not here to “help” others on their spiritual journey.

3. Remain skeptical about ideas, mentors, & gurus

Nobody truly has it figured out, and if they do, they certainly aren’t talking about it.

4. Embrace the beginner’s mind

Avoid bringing your preconceptions and opinions to new ideas. Act as though you’re a child experiencing everything for the first time.

5. Be conscious about your use of social media

This is especially important when it comes to sharing your spiritual development publicly. By sharing with others, you’re feeding the ego hiding behind the curtain.

6. Avoid over-intellectualizing spirituality

This comes at the expense of direct, personal, or experiential understandings of these concepts in daily life.

7. Beware of toxic positivity

This is the belief that no matter how dire or difficult a situation is, people should maintain a positive mindset. This invalidates an authentic human emotional experience and is a form of spiritual bypassing.

Zen Koans About Spiritual Arrogance

The beauty of Zen koans is that they can be used to “impart wisdom” that can’t otherwise be explained by words.

They’re told as a sort of joke — only the punchline isn’t spontaneous laughter — but spontaneous glimpses of enlightenment.

They all deliver some form of unexplainable wisdom that you either get at the punchline or you don’t. Just like a joke, if the koan has to be explained, it loses its power.

@ 3f770d65:7a745b24

I’ve been using Notedeck for several months, starting with its extremely early and experimental alpha versions, all the way to its current, more stable alpha releases. The journey has been fascinating, as I’ve had the privilege of watching it evolve from a concept into a functional and promising tool.

In its earliest stages, Notedeck was raw—offering glimpses of its potential but still far from practical for daily use. Even then, the vision behind it was clear: a platform designed to redefine how we interact with Nostr by offering flexibility and power for all users.

I'm very bullish on Notedeck. Why? Because Will Casarin is making it! Duh! 😂

Seriously though, if we’re reimagining the web and rebuilding portions of the Internet, it’s important to recognize the potential of Notedeck. If Nostr is reimagining the web, then Notedeck is reimagining the Nostr client.

Notedeck isn’t just another Nostr app—it’s more a Nostr browser that functions more like an operating system with micro-apps. How cool is that?

Much like how Google's Chrome evolved from being a web browser with a task manager into ChromeOS, a full blown operating system, Notedeck aims to transform how we interact with the Nostr. It goes beyond individual apps, offering a foundation for a fully integrated ecosystem built around Nostr.

As a Nostr evangelist, I love to scream INTEROPERABILITY and tout every application's integrations. Well, Notedeck has the potential to be one of the best platforms to showcase these integrations in entirely new and exciting ways.

Do you want an Olas feed of images? Add the media column.

Do you want a feed of live video events? Add the zap.stream column.

Do you want Nostr Nests or audio chats? Add that column to your Notedeck.

Git? Email? Books? Chat and DMs? It's all possible.

Not everyone wants a super app though, and that’s okay. As with most things in the Nostr ecosystem, flexibility is key. Notedeck gives users the freedom to choose how they engage with it—whether it’s simply following hashtags or managing straightforward feeds. You'll be able to tailor Notedeck to fit your needs, using it as extensively or minimally as you prefer.

Notedeck is designed with a local-first approach, utilizing Nostr content stored directly on your device via the local nostrdb. This will enable a plethora of advanced tools such as search and filtering, the creation of custom feeds, and the ability to develop personalized algorithms across multiple Notedeck micro-applications—all with unparalleled flexibility.

Notedeck also supports multicast. Let's geek out for a second. Multicast is a method of communication where data is sent from one source to multiple destinations simultaneously, but only to devices that wish to receive the data. Unlike broadcast, which sends data to all devices on a network, multicast targets specific receivers, reducing network traffic. This is commonly used for efficient data distribution in scenarios like streaming, conferencing, or large-scale data synchronization between devices.

In a local first world where each device holds local copies of your nostr nodes, and each device transparently syncs with each other on the local network, each node becomes a backup. Your data becomes antifragile automatically. When a node goes down it can resync and recover from other nodes. Even if not all nodes have a complete collection, negentropy can pull down only what is needed from each device. All this can be done without internet.

-Will Casarin

In the context of Notedeck, multicast would allow multiple devices to sync their Nostr nodes with each other over a local network without needing an internet connection. Wild.

Notedeck aims to offer full customization too, including the ability to design and share custom skins, much like Winamp. Users will also be able to create personalized columns and, in the future, share their setups with others. This opens the door for power users to craft tailored Nostr experiences, leveraging their expertise in the protocol and applications. By sharing these configurations as "Starter Decks," they can simplify onboarding and showcase the best of Nostr’s ecosystem.

Nostr’s “Other Stuff” can often be difficult to discover, use, or understand. Many users doesn't understand or know how to use web browser extensions to login to applications. Let's not even get started with nsecbunkers. Notedeck will address this challenge by providing a native experience that brings these lesser-known applications, tools, and content into a user-friendly and accessible interface, making exploration seamless. However, that doesn't mean Notedeck should disregard power users that want to use nsecbunkers though - hint hint.

For anyone interested in watching Nostr be developed live, right before your very eyes, Notedeck’s progress serves as a reminder of what’s possible when innovation meets dedication. The current alpha is already demonstrating its ability to handle complex use cases, and I’m excited to see how it continues to grow as it moves toward a full release later this year.

Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.

1. Criar uma carteira somente leitura em outro dispositivo, como seu celular ou computador pessoal, é uma etapa bastante simples. Para este tutorial, usaremos outro smartphone Android com Electrum. Instale o Electrum a partir da aba de downloads em https://electrum.org/ ou da própria Play Store. (ATENÇÃO: O Electrum não existe oficialmente para iPhone. Desconfie se encontrar algum.)

2. Após instalar o Electrum, crie uma carteira padrão, mas desta vez escolha a opção Usar uma chave mestra.

1. Agora, no assinador que criamos no primeiro módulo, exporte sua chave pública: vá em Carteira > Detalhes da carteira > Compartilhar chave mestra pública.

1. Escaneie o QR gerado da chave pública com o dispositivo de consulta. Assim, ele poderá acompanhar seus fundos, mas sem permissão para movimentá-los.

2. Para receber fundos, envie Bitcoin para um dos endereços gerados pela sua carteira: Carteira > Addresses/Coins.

3. Para movimentar fundos, crie uma transação no dispositivo de consulta. Como ele não possui a chave privada, será necessário assiná-la com o dispositivo assinador.

1. No assinador, escaneie a transação não assinada, confirme os detalhes, assine e compartilhe. Será gerado outro QR, desta vez com a transação já assinada.

1. No dispositivo de consulta, escaneie o QR da transação assinada e transmita-a para a rede.

Conclusão

Pontos positivos do setup:

• Simplicidade: Basta um dispositivo Android antigo.
• Flexibilidade: Funciona como uma ótima carteira fria, ideal para holders.

Pontos negativos do setup:

• Padronização: Não utiliza seeds no padrão BIP-39, você sempre precisará usar o electrum.
• Interface: A aparência do Electrum pode parecer antiquada para alguns usuários.

Nesse ponto, temos uma carteira fria que também serve para assinar transações. O fluxo de assinar uma transação se torna: Gerar uma transação não assinada > Escanear o QR da transação não assinada > Conferir e assinar essa transação com o assinador > Gerar QR da transação assinada > Escanear a transação assinada com qualquer outro dispositivo que possa transmiti-la para a rede.

Como alguns devem saber, uma transação assinada de Bitcoin é praticamente impossível de ser fraudada. Em um cenário catastrófico, você pode mesmo que sem internet, repassar essa transação assinada para alguém que tenha acesso à rede por qualquer meio de comunicação. Mesmo que não queiramos que isso aconteça um dia, esse setup acaba por tornar essa prática possível.

Imagine a world where clean, safe, and efficient nuclear power can be delivered to any corner of the globe, powering everything from small villages to bustling cities. This vision is becoming a reality with the development of nuclear modular plants—compact, portable nuclear reactors that can be shipped in standard containers and set up quickly to provide reliable energy. These innovative power sources use fission—the process of splitting atomic nuclei to release energy, the same fundamental principle that powers traditional nuclear plants—but with a twist: they utilize thorium as fuel and a molten salt system for cooling and fuel delivery. This combination offers a host of benefits that could revolutionize how we think about nuclear energy.

Portability and Deployment

One of the most significant advantages of these nuclear modular plants is their portability. Designed to fit within standard shipping containers, these reactors can be transported by truck, ship, or even air to virtually any location. This makes them ideal for remote communities, disaster relief efforts, or military operations where traditional power infrastructure is lacking or damaged. Setting up a conventional power plant typically takes years, but these modular units can be operational in a matter of weeks, providing a rapid solution to energy needs.

Safety Features

Safety is a paramount concern in nuclear energy, and modular thorium molten salt reactors (MSRs) offer several inherent safety advantages. Unlike traditional reactors that use water under high pressure, MSRs operate at atmospheric pressure, eliminating the risk of pressure-related accidents. The fuel is dissolved in the molten salt, which means there's no solid fuel that could melt down. If the reactor overheats, the salt expands, naturally slowing the fission reaction—a built-in safety mechanism. Additionally, thorium-based fuels produce less long-lived radioactive waste, reducing the long-term environmental impact.

Efficiency and Abundance

Thorium is a more abundant resource than uranium, with estimates suggesting it is three to four times more plentiful in the Earth's crust. This abundance makes thorium a sustainable fuel choice for the future. Moreover, MSRs can operate at higher temperatures than traditional reactors, leading to greater thermal efficiency. This means more electricity can be generated from the same amount of fuel, making the energy production process more efficient and cost-effective in the long run.

Scalability

The modular design of these reactors allows for scalability to meet varying power demands. A single unit might power a small community, while multiple units can be combined to serve larger towns or cities. This flexibility is particularly useful for growing populations or regions with fluctuating energy needs. As demand increases, additional modules can be added without the need for extensive new infrastructure.

Cost-Effectiveness

While the initial investment in nuclear modular plants may be significant, the long-term operational costs can be lower than traditional power sources. The high efficiency of MSRs means less fuel is needed over time, and the reduced waste production lowers disposal costs. Additionally, the ability to mass-produce these modular units could drive down manufacturing costs, making nuclear power more accessible and affordable.

Environmental Impact

Nuclear power is already one of the cleanest energy sources in terms of carbon emissions, and thorium MSRs take this a step further. By producing less long-lived waste and utilizing a more abundant fuel, these reactors offer a more sustainable path for nuclear energy. Furthermore, their ability to provide reliable baseload power can help reduce reliance on fossil fuels, contributing to global efforts to combat climate change.

Challenges and Considerations

Despite these benefits, there are challenges to overcome before nuclear modular plants can be widely deployed. The technology for thorium MSRs is still in the developmental stage, with ongoing research needed to address issues such as material corrosion and fuel processing. Regulatory frameworks will also need to adapt to this new type of reactor, and public perception of nuclear energy remains a hurdle in many regions. However, with continued investment and innovation, these obstacles can be addressed.

Conclusion

In conclusion, nuclear modular plants using thorium and molten salt systems represent a promising advancement in nuclear technology. Their portability, safety features, efficiency, scalability, and environmental benefits make them an attractive option for meeting the world's growing energy needs. While challenges remain, the potential of these reactors to provide clean, reliable power to communities around the globe is undeniable. As research and development continue, we may soon see a new era of nuclear energy that is safer, more efficient, and more accessible than ever before.

El Gran Apagón y la Tormenta Perfecta: ¿Hacia Dónde Nos Llevan?

Recientemente, un corte de luz masivo dejó a oscuras a España, Portugal y parte de Francia. Como suele pasar cuando las explicaciones escasean o no se quieren dar, la narrativa oficial apuntó al cambio climático. Un artículo de ABC sugiere que una "vibración atmosférica inducida" por "variaciones extremas de temperatura" podría ser la culpable (ABC, 28/04/2025). Pero, ¿es realmente el calentamiento global el villano de esta historia, o estamos ante un síntoma de algo más grande y complejo?

Una Red de Decisiones Interconectadas

Nada ocurre en el vacío, y este apagón no es una excepción. La generación de electricidad, cada vez más dependiente de fuentes renovables no convencionales, enfrenta retos de estabilidad y costos crecientes. A esto se suma la presión política para transformar nuestras vidas bajo la bandera de la sostenibilidad. Por ejemplo, la idea de la "ciudad de 15 minutos", donde todo lo que necesitas está a un corto paseo o pedaleo, suena ideal. Pero en lugares como el Reino Unido, esta visión viene acompañada de cámaras de vigilancia que controlan tus movimientos, justificadas por la "seguridad" o la "eficiencia".

Mientras tanto, la Unión Europea avanza hacia un futuro donde, para 2030, todos los autos deberán ser eléctricos. Con una red eléctrica inestable y precios de energía disparados, ¿cómo se supone que cargaremos esos vehículos? La respuesta parece ser: no lo hagas. Muévete en bicicleta, quédate cerca de casa. La movilidad, un símbolo de libertad, se está restringiendo para las masas, mientras la élite política y corporativa sigue surcando los cielos en jets privados para "combatir el cambio climático" o, como Bernie Sanders y AOC, para denunciar la oligarquía desde sus podios privilegiados.

Dependencia Eléctrica: Una Trampa Silenciosa

La electrificación no se detiene en los autos. Los edificios modernos tienden a ser completamente eléctricos, y en algunos lugares ya se habla de prohibir las cocinas a gas. Imagina un futuro donde dependes de la red eléctrica para cocinar una simple salchicha. Ahora, suma un apagón como el reciente. Sin electricidad, no hay cena, no hay calefacción, no hay nada. La automatización total, que nos venden como progreso, nos hace más vulnerables a estos colapsos.

El Euro Digital: Control Absoluto

La Unión Europea también está empujando el euro digital, una moneda que promete conveniencia, pero a un costo altísimo. Con ella, cada transacción será rastreable, y las autoridades podrían restringir su uso para ciertos fines o incluso "quemar" euros digitales a voluntad para controlar su valor frente a otras monedas. ¿Qué pasa con la libertad financiera? ¿Qué pasa con la privacidad? Este sistema, combinado con una red eléctrica frágil, pinta un panorama donde el ciudadano promedio queda atrapado en una jaula tecnológica.

Criptomonedas, Efectivo y Oro: ¿Alternativas Reales?

Las criptomonedas, que muchos ven como una salida, también son vulnerables a los cortes de energía. Sin electricidad, no hay blockchain. El efectivo, por su parte, sigue siendo una opción, pero se desgasta, pierde valor con la inflación y, en muchos lugares, está siendo demonizado en favor de pagos digitales. Luego está el oro, el refugio histórico. Pero incluso aquí hay trampas: viajar con oro puede convertirte en sospechoso en un aeropuerto, obligado a explicar el origen de tu propiedad. ¿Desde cuándo debemos justificar lo que es nuestro? ¿Dónde quedó la presunción de inocencia?

"No Tendrás Nada y Serás Feliz"

Cuando uno conecta los puntos —apagones, electrificación forzada, monedas digitales, restricciones de movilidad— es difícil no pensar en el famoso eslogan atribuido al Foro Económico Mundial: "No tendrás nada y serás feliz". Mencionarlo te hace ganar el sello de "conspiranóico", pero las señales están ahí. La pregunta es: ¿estamos caminando hacia un futuro de control total disfrazado de sostenibilidad, o es solo una serie de coincidencias desafortunadas?

Inter-op All The Things

Nostr is a new open social protocol for the internet. This open nature exciting because of the opportunities for interoperability with other technologies. In Using NFC Cards with Nostr I explored the nostr: URI to launch Nostr clients from a card tap.

The interoperability of Nostr doesn't stop there. The internet has many super-powers, and Nostr is open to all of them. Simply, there's no one to stop it. There is no one in charge, there are no permissioned APIs, and there are no risks of being de-platformed. If you can imagine technologies that would work well with Nostr, then any and all of them can ride on or alongside Nostr rails.

My mental model for why this is special is Google Wave ~2010. Google Wave was to be the next big platform. Lars was running it and had a big track record from Maps. I was excited for it. Then, Google pulled the plug. And, immediately all the time and capital invested in understanding and building on the platform was wasted.

This cannot happen to Nostr, as there is no one to pull the plug, and maybe even no plug to pull.

So long as users demand Nostr, Nostr will exist, and that is a pretty strong guarantee. It makes it worthwhile to invest in bringing Nostr into our other applications.

All we need are simple ways to plug things together.

Nostr and Workflow Automation

Workflow automation is about helping people to streamline their work. As a user, the most common way I achieve this is by connecting disparate systems together. By setting up one system to trigger another or to move data between systems, I can solve for many different problems and become way more effective.

n8n for workflow automation

Many workflow automation tools exist. My favourite is n8n. n8n is a low/no-code workflow automation platform which allows you to build all kinds of workflows. You can use it for free, you can self-host it, it has a user-friendly UI and useful API. Vs Zapier it can be far more elaborate. Vs Make.com I find it to be more intuitive in how it abstracts away the right parts of the code, but still allows you to code when you need to.

Most importantly you can plug anything into n8n: You have built-in nodes for specific applications. HTTP nodes for any other API-based service. And community nodes built by individual community members for any other purpose you can imagine.

Eating my own dogfood

It's very clear to me that there is a big design space here just demanding to be explored. If you could integrate Nostr with anything, what would you do?

In my view the best way for anyone to start anything is by solving their own problem first (aka "scratching your own itch" and "eating your own dogfood"). As I get deeper into Nostr I find myself controlling multiple Npubs – to date I have a personal Npub, a brand Npub for a community I am helping, an AI assistant Npub, and various testing Npubs. I need ways to delegate access to those Npubs without handing over the keys, ways to know if they're mentioned, and ways to know if they're posting.

I can build workflows with n8n to solve these issues for myself to start with, and keep expanding from there as new needs come up.

Running n8n with Nostrobots

I am mostly non-technical with a very helpful AI. To set up n8n to work with Nostr and operate these workflows should be possible for anyone with basic technology skills.

• I have a cheap VPS which currently runs my HAVEN Nostr Relay and Albyhub Lightning Node in Docker containers,
• My objective was to set up n8n to run alongside these in a separate Docker container on the same server, install the required nodes, and then build and host my workflows.

Installing n8n

Self-hosting n8n could not be easier. I followed n8n's Docker-Compose installation docs–

• Install Docker and Docker-Compose if you haven't already,
• Create your docker-compose.yml and .env files from the docs,
• Create your data folder sudo docker volume create n8n_data,
• Start your container with sudo docker compose up -d,
• Your n8n instance should be online at port 5678.

n8n is free to self-host but does require a license. Enter your credentials into n8n to get your free license key. You should now have access to the Workflow dashboard and can create and host any kind of workflows from there.

Installing Nostrobots

To integrate n8n nicely with Nostr, I used the Nostrobots community node by Ocknamo.

In n8n parlance a "node" enables certain functionality as a step in a workflow e.g. a "set" node sets a variable, a "send email" node sends an email. n8n comes with all kinds of "official" nodes installed by default, and Nostr is not amongst them. However, n8n also comes with a framework for community members to create their own "community" nodes, which is where Nostrobots comes in.

You can only use a community node in a self-hosted n8n instance (which is what you have if you are running in Docker on your own server, but this limitation does prevent you from using n8n's own hosted alternative).

To install a community node, see n8n community node docs. From your workflow dashboard–

• Click the "..." in the bottom left corner beside your username, and click "settings",
• Cilck "community nodes" left sidebar,
• Click "Install",
• Enter the "npm Package Name" which is n8n-nodes-nostrobots,
• Accept the risks and click "Install",
• Nostrobots is now added to your n8n instance.

Using Nostrobots

Nostrobots gives you nodes to help you build Nostr-integrated workflows–

• Nostr Write – for posting Notes to the Nostr network,
• Nostr Read – for reading Notes from the Nostr network, and
• Nostr Utils – for performing certain conversions you may need (e.g. from bech32 to hex).

Nostrobots has good documentation on each node which focuses on simple use cases.

Each node has a "convenience mode" by default. For example, the "Read" Node by default will fetch Kind 1 notes by a simple filter, in Nostrobots parlance a "Strategy". For example, with Strategy set to "Mention" the node will accept a pubkey and fetch all Kind 1 notes that Mention the pubkey within a time period. This is very good for quick use.

What wasn't clear to me initially (until Ocknamo helped me out) is that advanced use cases are also possible.

Each node also has an advanced mode. For example, the "Read" Node can have "Strategy" set to "RawFilter(advanced)". Now the node will accept json (anything you like that complies with NIP-01). You can use this to query Notes (Kind 1) as above, and also Profiles (Kind 0), Follow Lists (Kind 3), Reactions (Kind 7), Zaps (Kind 9734/9735), and anything else you can think of.

Creating and adding workflows

With n8n and Nostrobots installed, you can now create or add any kind of Nostr Workflow Automation.

• Click "Add workflow" to go to the workflow builder screen,
• If you would like to build your own workflow, you can start with adding any node. Click "+" and see what is available. Type "Nostr" to explore the Nostrobots nodes you have added,
• If you would like to add workflows that someone else has built, click "..." in the top right. Then click "import from URL" and paste in the URL of any workflow you would like to use (including the ones I share later in this article).

Nostr Workflow Automations

It's time to build some things!

A simple form to post a note to Nostr

I started very simply. I needed to delegate the ability to post to Npubs that I own in order that a (future) team can test things for me. I don't want to worry about managing or training those people on how to use keys, and I want to revoke access easily.

I needed a basic form with credentials that posted a Note.

For this I can use a very simple workflow–

• A n8n Form node – Creates a form for users to enter the note they wish to post. Allows for the form to be protected by a username and password. This node is the workflow "trigger" so that the workflow runs each time the form is submitted.
• A Set node – Allows me to set some variables, in this case I set the relays that I intend to use. I typically add a Set node immediately following the trigger node, and put all the variables I need in this. It helps to make the workflows easier to update and maintain.
• A Nostr Write node (from Nostrobots) – Writes a Kind-1 note to the Nostr network. It accepts Nostr credentials, the output of the Form node, and the relays from the Set node, and posts the Note to those relays.

Once the workflow is built, you can test it with the testing form URL, and set it to "Active" to use the production form URL. That's it. You can now give posting access to anyone for any Npub. To revoke access, simply change the credentials or set to workflow to "Inactive".

It may also be the world's simplest Nostr client.

You can find the Nostr Form to Post a Note workflow here.

Push notifications on mentions and new notes

One of the things Nostr is not very good at is push notifications. Furthermore I have some unique itches to scratch. I want–

• To make sure I never miss a note addressed to any of my Npubs – For this I want a push notification any time any Nostr user mentions any of my Npubs,
• To make sure I always see all notes from key accounts – For this I need a push notification any time any of my Npubs post any Notes to the network,
• To get these notifications on all of my devices – Not just my phone where my Nostr regular client lives, but also on each of my laptops to suit wherever I am working that day.

I needed to build a Nostr push notifications solution.

To build this workflow I had to string a few ideas together–

• Triggering the node on a schedule – Nostrobots does not include a trigger node. As every workflow starts with a trigger we needed a different method. I elected to run the workflow on a schedule of every 10-minutes. Frequent enough to see Notes while they are hot, but infrequent enough to not burden public relays or get rate-limited,
• Storing a list of Npubs in a Nostr list – I needed a way to store the list of Npubs that trigger my notifications. I initially used an array defined in the workflow, this worked fine. Then I decided to try Nostr lists (NIP-51, kind 30000). By defining my list of Npubs as a list published to Nostr I can control my list from within a Nostr client (e.g. Listr.lol or Nostrudel.ninja). Not only does this "just work", but because it's based on Nostr lists automagically Amethyst client allows me to browse that list as a Feed, and everyone I add gets notified in their Mentions,
• Using specific relays – I needed to query the right relays, including my own HAVEN relay inbox for notes addressed to me, and wss://purplepag.es for Nostr profile metadata,
• Querying Nostr events (with Nostrobots) – I needed to make use of many different Nostr queries and use quite a wide range of what Nostrobots can do–
  • I read the EventID of my Kind 30000 list, to return the desired pubkeys,
  • For notifications on mentions, I read all Kind 1 notes that mention that pubkey,
  • For notifications on new notes, I read all Kind 1 notes published by that pubkey,
  • Where there are notes, I read the Kind 0 profile metadata event of that pubkey to get the displayName of the relevant Npub,
  • I transform the EventID into a Nevent to help clients find it.
• Using the Nostr URI – As I did with my NFC card article, I created a link with the nostr: URI prefix so that my phone's native client opens the link by default,
• Push notifications solution – I needed a push notifications solution. I found many with n8n integrations and chose to go with Pushover which supports all my devices, has a free trial, and is unfairly cheap with a $5-per-device perpetual license.

Once the workflow was built, lists published, and Pushover installed on my phone, I was fully set up with push notifications on Nostr. I have used these workflows for several weeks now and made various tweaks as I went. They are feeling robust and I'd welcome you to give them a go.

You can find the Nostr Push Notification If Mentioned here and If Posts a Note here.

In speaking with other Nostr users while I was building this, there are all kind of other needs for push notifications too – like on replies to a certain bookmarked note, or when a followed Npub starts streaming on zap.stream. These are all possible.

Use my workflows

I have open sourced all my workflows at my Github with MIT license and tried to write complete docs, so that you can import them into your n8n and configure them for your own use.

To import any of my workflows–

• Click on the workflow of your choice, e.g. "Nostr_Push_Notify_If_Mentioned.json",
• Click on the "raw" button to view the raw JSON, ex any Github page layout,
• Copy that URL,
• Enter that URL in the "import from URL" dialog mentioned above.

To configure them–

• Prerequisites, credentials, and variables are all stated,
• In general any variables required are entered into a Set Node that follows the trigger node,
• Pushover has some extra setup but is very straightforward and documented in the workflow.

What next?

Over my first four blogs I explored creating a good Nostr setup with Vanity Npub, Lightning Payments, Nostr Addresses at Your Domain, and Personal Nostr Relay.

Then in my latest two blogs I explored different types of interoperability with NFC cards and now n8n Workflow Automation.

Thinking ahead n8n can power any kind of interoperability between Nostr and any other legacy technology solution. On my mind as I write this:

• Further enhancements to posting and delegating solutions and forms (enhanced UI or different note kinds),
• Automated or scheduled posting (such as auto-liking everything Lyn Alden posts),
• Further enhancements to push notifications, on new and different types of events (such as notifying me when I get a new follower, on replies to certain posts, or when a user starts streaming),
• All kinds of bridges, such as bridging notes to and from Telegram, Slack, or Campfire. Or bridging RSS or other event feeds to Nostr,
• All kinds of other automation (such as BlackCoffee controlling a coffee machine),
• All kinds of AI Assistants and Agents,

In fact I have already released an open source workflow for an AI Assistant, and will share more about that in my next blog.

Please be sure to let me know if you think there's another Nostr topic you'd like to see me tackle.

Is the internet making us dumber?

The answer to this question depends on how we define intelligence. If it refers to the number of facts we know and we remember — the answer is probably “yes.”

A study led by Betsy Sparrow on the impact of Google on human memory states that:

“When people expect to have future access to information, they have lower rates of recall of the information itself and enhanced recall instead for where to access it. The Internet has become a primary form of external or transactive memory, where information is stored collectively outside ourselves.”

That might not be such a bad thing — in theory, it could help preserve our limited cognitive capacity for more salient tasks, such as learning new skills, achieving mastery in our chosen domain, or soul-enriching creative pursuits. Is it really that important that we remember exactly how deep the lowest part of the ocean is or how many species of birds there are?

Maybe, maybe not.

If intelligence is measured by our ability to understand and process information — the answer is much more complicated. It depends entirely on how we use it.

Before we explore all the ways the internet undermines our cognitive abilities, I have to point out that access to the internet can easily be used to make us smarter, happier, and more connected. This is a technology that allows us to learn anything we want — quickly and cheaply. Education is no longer a privilege reserved for the rich. Now, anybody with access to a public library or a $100 smartphone can access information on any topic.

The problem is that the unfettered and unconscious use of the internet lures us into delusion and distraction.

Here are 5 ways the internet makes us dumber and some strategies for resisting them.

1. Information Overload

“The man who chases two rabbits catches none.” — Old Zen Parable.

Information overload is a problem where one is given so much information at one time they become overwhelmed and unable to process or think about it in a clear way.

We are inundated with so much information these days that we don’t even know how to make sense of it. We’re overloaded. Our attention spans are short, and we have no time leftover for deep, contemplative thought about the information we consume.

One study even found that simply having a smartphone nearby reduces one’s cognitive capacity. This study points to the “brain drain” hypothesis, which suggests that the brain has a finite amount of processing power and the mere presence of a potential distractor (like our smartphones) can occupy a large portion of these resources.

When we feel overwhelmed, we double down and attempt to cram as much information as possible  — we skim 10 different articles at a time without reading anything, fast-forward through YouTube videos to try and find the most interesting parts, ask GPTs to summarize books so we don’t have to read them, and throw videos and podcasts on in the background while working on something else.

The problem is that we just aren’t very good at multitasking. Instead, our attention rapidly (and inefficiently) switches from one task to another. The process of switching focus back and forth requires additional cognitive processes that further reduce the overall capacity of the brain.

“Wherever you are, be there totally.” — Eckhart Tolle

2. Fake News

“Fake news and rumors thrive online because few verify what's real and always bias towards content that reinforces their own biases.” — Ryan Higa

The freedom of the internet means anybody can publish anything and position it as fact. Much of the information we find online is wrong, out of context, or intentionally misleading. Whether this fake information was created out of ignorance or malicious intent doesn’t really matter.

Our ability to distinguish fiction from reality becomes more difficult when we’re saturated with information. Who has the time to fact-check every article they read online?

Another major factor contributing to this issue is the proliferation of bot accounts on social media — a phenomenon that makes up a significant portion of social media profiles these days. Many of these accounts exist for the sole purpose of flooding social media with low-quality information to manipulate human behavior, ideology, and opinions. Sometimes, this is to sell you something; other times, it’s to influence the opinions of society at-large.

Despite the issue with fake news, 50% of people still get most of their news from social media — according to research conducted by Pew Research Center.

The emergence of deepfakes and AI-generated misinformation are making this problem even worse. It’s becoming easier for bad actors to generate and spread false or misleading information throughout the internet in massive quantities.

3. Junk Info

“Treat junk information the way you treat junk food. Realize that it’s crap that tastes good, and consume it sparingly. Monitor your consumption and ensure that you never trick yourself into believing it’s good for you.” — Daniel Miessler

The internet is saturated with junk information — which not only includes information that’s factually incorrect but also those with no practical use. It doesn’t make our lives any better, it doesn’t make us smarter or more capable humans, and it certainly doesn’t make us happier or more present in our lives.

Examples include clickbait, ragebait, gossip, conspiracy theories, babel, or trivial social media status updates. These types of content grab our attention just as much as high-quality content but leave us feeling empty and unsatisfied. This is why you can spend 2 hours scrolling on Instagram or Twitter, only to log off and discover you can’t remember a single piece of information you just consumed.

A major factor driving this phenomenon is that low-quality information provides us with the same dopamine hit as high-quality information but is significantly easier to manufacture. Publishers like Buzzfeed and Bored Panda take advantage of this fact by mass-producing junk information on a scale never before seen in human history.

Gurwinder eloquently describes the crisis of intellectual obesity as follows:

“Just as gorging on junk food bloats your body, so gorging on junk info bloats your mind, filling it with a cacophony of half-remembered gibberish that sidetracks your attention and confuses your senses. Unable to distinguish between relevant and irrelevant, you become concerned by trivialities and outraged by falsehoods. These concerns and outrages push you to consume even more, and all the time that you're consuming, you're prevented from doing anything else: learning, focusing, even thinking. The result is that your stream of consciousness becomes clogged; you develop atherosclerosis of the mind.”

4. Cognitive Bias

“The foolish reject what they see, not what they think — the wise reject what they think, not what they see.” — Huang Po

Cognitive bias refers to the systematic ways in which the context and framing of information influence individuals' judgment and decision-making.

The internet often acts as an echo chamber, where algorithms tailor content to our existing beliefs, reinforcing our biases rather than challenging them.

Confirmation bias, for instance, leads us to favor information that aligns with our preconceptions and dismiss evidence that contradicts them. This bias is magnified online, where we can easily find sources that support any viewpoint, no matter how fringe or unfounded. As a result, our beliefs become more entrenched, and we become less open to opposing perspectives.

Another example is the availability heuristic, which causes us to overestimate the importance of information that is readily available to us. Social media amplifies this bias by prioritizing trending topics, sensational stories, and viral content, often at the expense of more balanced or nuanced viewpoints. This can lead to distorted perceptions of reality, where rare but dramatic events seem more common than they are.

There’s also the bandwagon effect, where people adopt beliefs or behaviors because they see others doing the same. Social media platforms capitalize on this bias by prominently displaying popular posts and trending hashtags, encouraging us to conform to the majority opinion without critically evaluating the information.

5. The Attention Economy

“We find ourselves in a new stage of capitalism. One that is predicated on the ever more aggressive appropriation of our attention, often by mechanized means. This makes cultivating the habits and pleasures of deep, slow thinking a difficult matter.” — Matthew Crawford.

The attention economy is a marketplace in which human attention is treated as a scarce commodity. It’s becoming increasingly sought-after by advertisers.

The key metrics of success in this marketplace are to capture our attention with engaging content, retain it through various psychological tricks and manipulations, and milk our minds for ad dollars. The unfortunate side effect of this is that these manipulations further degrade our ability to think clearly and form logical opinions.

Attention is an important part of the human experience. It’s what connects us with the outside world. Even outside the realm of the internet, different forms of stimuli are constantly seeking our attention — we’ve evolved various internal mechanisms to ignore what isn’t important so we can preserve our energy for what is.

Through the magic of the internet, companies have learned ways to infiltrate our minds and override these internal defense mechanisms.

Just like any other commodity, human attention is subject to the rules of supply and demand. Our personal supply of attention is finite — there’s only so much time in a day, so our attention can only be given to a limited number of things. Tech companies need to innovate ways to maximize the amount of users that interact with their product and extend the time each person is willing to remain engaged.

How Apps Manipulate Our Emotions & Harvest Our Attention

“It is very common for humans to develop things with the best of intentions that have unintended, negative consequences.” — Justin Rosenstein, creator of the 'like' button.

Social media apps use numerous psychological tactics to induce emotions that keep us on the platform.

Here are just a few of the subtle design tweaks these apps employ that unconsciously manipulate our emotions:

• Using the color red for notifications — Red is a trigger color, inducing a sense of alarm. Facebook used to use a blue notification icon (to match their logo); however, developers noted that nobody was paying attention, so they changed it to red, and suddenly, engagement with the feature skyrocketed.

• Variable rewards — The notification centers of apps intentionally hide the specifics of our interactions to keep us in a state of anticipation. It could be a whole bunch of new likes, some new followers, or absolutely nothing at all. The anticipation of not knowing what kind of surprises could be in store for us is exciting, and clicking the dropdown to explore becomes a compulsive habit.

• The pull-to-refresh feature — This loading feature was a happy accident. Loren Brichter invented it for his app, Tweetie (before it was bought by Twitter), simply because there wasn’t a good space to add a refresh button. However, this invention turned out to be a boon for manipulating users' emotions. The little “loading” animation makes us think it’s gathering data, but this delay is intentional. It gives us a sense of anticipation, which is addicting… sort of like the pull of a slot machine.

• Infinite scrolling — Users can continuously scroll through content without ever hitting a stopping point. This design keeps users engaged for long periods of time as there’s always something new just a swipe away. It takes advantage of our natural inclination to keep looking for more information and makes it hard to break free from the app.

• Social validation loops — Features like likes, comments, and shares create a feedback loop that keeps users coming back for more. Each notification of social validation triggers a release of dopamine, reinforcing the behavior and making users more likely to continue engaging with the app in search of more juicy validation.

# Tech Execs Who Refuse to Get High on Their Own Supply

Nobody understands the power of gaming human attention than the tech executives and developers working behind the scenes to keep us hooked on their products.

Over the years, several high-profile individuals working for Google, Meta, Twitter, and Apple have disclosed some of the extreme lengths they go through to avoid getting sucked into the cognitive wormholes their products create.

Here are just a few examples:

Nir Eyal

(Tech consultant and author of Hooked: How to Build Habit-Forming Products and Indistractable: How to Control Your Attention and Choose Your Life).

Nir Eyal once confided in the lengths he goes to protect his own family from the addictive nature of unfettered internet access in an interview with Thrive Global.

Eyal shuts his phone off at 10 pm and keeps it out of his bedroom while he sleeps. He’s even installed an outlet timer on his home router to cut off internet access for his whole house at the same time every day.

“The idea is to remember that we are not powerless. We are in control.”

Justin Rosenstein

(Creator of the like button).

Justin reports that he’s tweaked his laptop’s operating system to block Reddit, banned himself from Snapchat (which he compares to heroin), and imposed limits on his use of Facebook.

But even that wasn’t enough.

Last year, Justin took an even more radical approach to restrict his use of addictive technologies. He ordered a new phone and asked his assistant to set up parental controls that block him from downloading any new apps.

Loren Brichter

(Designer of the pull-to-refresh feature).

Brichter, like other tech execs, has blocked certain websites, turned off push notifications, restricted his use of the Telegram app to message only with his wife and two close friends, and tried to wean himself off Twitter.

“I still waste time on it just reading stupid news I already know about.”

He charges his phone in the kitchen, plugging it in at 7 pm and not touching it until the next morning.

Tristan Harris

(Co-founder of the Center for Humane Technology and former Google design ethicist).

Tristan Harris, who has been vocal about the manipulative design practices of tech companies for years, takes various steps to protect himself. He uses a grayscale screen on his phone to make it less appealing and has removed all social media apps. Harris also sets specific times for checking emails and messages, ensuring that he’s not constantly distracted throughout the day.

“There’s a hidden goal driving all of our technology, and that goal is the race for our attention.”

# Becoming Smarter in the Age of Information

The internet is a double-edged sword. It’s a place we can go to learn, connect, and create, but also a source of delusion, distraction, and misinformation.

Learning to navigate and engage with it wisely can ultimately help us grow to become more present, focused, and content in our daily activities — but only if we establish a foundation of discipline and intentionality.

None of these concepts are new. People like Marshall McLuhan have been talking about the influence of electronic media several years before the internet was even invented.

However, as technologies become more sophisticated and pervasive in our daily lives, we’re learning to adapt and find balance.

In the spirit of acknowledging our need for quick, bite-sized information snippets (wink wink), I’ll conclude with 10 quick strategies we can adopt to resist the distractions of the internet and preserve our cognitive resources to become smarter, happier, more capable humans.

10 Strategies to Thrive in the Information Age

1. Silo your attention — focus on one thing at a time.

2. Avoid going to social media for news.

3. Identify and limit junk information.

4. Seek out diverse perspectives and challenge your cognitive biases.

5. Treat your time and attention with respect — prioritize activities that enrich your life.

6. Limit internet and device usage — consider placing an outlet timer on your internet router.

7. Block or delete distracting websites and apps.

8. Implement grayscale screens.

9. Charge your phone outside your bedroom at night.

10. Practice tech-free days.

Scuttlebutt foi iniciado em maio de 2014 por Dominic Tarr ( dominictarr ) como uma rede social alternativa off-line, primeiro para convidados, que permite aos usuários obter controle total de seus dados e privacidade. Secure Scuttlebutt (ssb) foi lançado pouco depois, o que coloca a privacidade em primeiro plano com mais recursos de criptografia.

Se você está se perguntando de onde diabos veio o nome Scuttlebutt:

Este termo do século 19 para uma fofoca vem do Scuttlebutt náutico: “um barril de água mantido no convés, com um buraco para uma xícara”. A gíria náutica vai desde o hábito dos marinheiros de se reunir pelo boato até a fofoca, semelhante à fofoca do bebedouro.

Marinheiros se reunindo em torno da rixa. ( fonte )

Dominic descobriu o termo boato em um artigo de pesquisa que leu.

Em sistemas distribuídos, fofocar é um processo de retransmissão de mensagens ponto a ponto; as mensagens são disseminadas de forma análoga ao “boca a boca”.

Secure Scuttlebutt é um banco de dados de feeds imutáveis apenas para acréscimos, otimizado para replicação eficiente para protocolos ponto a ponto. Cada usuário tem um log imutável somente para acréscimos no qual eles podem gravar. Eles gravam no log assinando mensagens com sua chave privada. Pense em um feed de usuário como seu próprio diário de bordo, como um diário de bordo (ou diário do capitão para os fãs de Star Trek), onde eles são os únicos autorizados a escrever nele, mas têm a capacidade de permitir que outros amigos ou colegas leiam ao seu diário de bordo, se assim o desejarem.

Cada mensagem possui um número de sequência e a mensagem também deve fazer referência à mensagem anterior por seu ID. O ID é um hash da mensagem e da assinatura. A estrutura de dados é semelhante à de uma lista vinculada. É essencialmente um log somente de acréscimo de JSON assinado. Cada item adicionado a um log do usuário é chamado de mensagem.

Os logs do usuário são conhecidos como feed e um usuário pode seguir os feeds de outros usuários para receber suas atualizações. Cada usuário é responsável por armazenar seu próprio feed. Quando Alice assina o feed de Bob, Bob baixa o log de feed de Alice. Bob pode verificar se o registro do feed realmente pertence a Alice verificando as assinaturas. Bob pode verificar as assinaturas usando a chave pública de Alice.

Estrutura de alto nível de um feed

Pubs são servidores de retransmissão conhecidos como “super peers”. Pubs conectam usuários usuários e atualizações de fofocas a outros usuários conectados ao Pub. Um Pub é análogo a um pub da vida real, onde as pessoas vão para se encontrar e se socializar. Para ingressar em um Pub, o usuário deve ser convidado primeiro. Um usuário pode solicitar um código de convite de um Pub; o Pub simplesmente gerará um novo código de convite, mas alguns Pubs podem exigir verificação adicional na forma de verificação de e-mail ou, com alguns Pubs, você deve pedir um código em um fórum público ou chat. Pubs também podem mapear aliases de usuário, como e-mails ou nome de usuário, para IDs de chave pública para facilitar os pares de referência.

Depois que o Pub enviar o código de convite ao usuário, o usuário resgatará o código, o que significa que o Pub seguirá o usuário, o que permite que o usuário veja as mensagens postadas por outros membros do Pub, bem como as mensagens de retransmissão do Pub pelo usuário a outros membros do Pub.

Além de retransmitir mensagens entre pares, os Pubs também podem armazenar as mensagens. Se Alice estiver offline e Bob transmitir atualizações de feed, Alice perderá a atualização. Se Alice ficar online, mas Bob estiver offline, não haverá como ela buscar o feed de Bob. Mas com um Pub, Alice pode buscar o feed no Pub mesmo se Bob estiver off-line porque o Pub está armazenando as mensagens. Pubs são úteis porque assim que um colega fica online, ele pode sincronizar com o Pub para receber os feeds de seus amigos potencialmente offline.

Um usuário pode, opcionalmente, executar seu próprio servidor Pub e abri-lo ao público ou permitir que apenas seus amigos participem, se assim o desejarem. Eles também podem ingressar em um Pub público. Aqui está uma lista de Pubs públicos em que todos podem participar . Explicaremos como ingressar em um posteriormente neste guia. Uma coisa importante a observar é que o Secure Scuttlebutt em uma rede social somente para convidados significa que você deve ser “puxado” para entrar nos círculos sociais. Se você responder às mensagens, os destinatários não serão notificados, a menos que estejam seguindo você de volta. O objetivo do SSB é criar “ilhas” isoladas de redes pares, ao contrário de uma rede pública onde qualquer pessoa pode enviar mensagens a qualquer pessoa.

Scuttlebot

O software Pub é conhecido como servidor Scuttlebutt (servidor ssb ), mas também é conhecido como “Scuttlebot” e sbotna linha de comando. O servidor SSB adiciona comportamento de rede ao banco de dados Scuttlebutt (SSB). Estaremos usando o Scuttlebot ao longo deste tutorial.

Os logs do usuário são conhecidos como feed e um usuário pode seguir os feeds de outros usuários para receber suas atualizações. Cada usuário é responsável por armazenar seu próprio feed. Quando Alice assina o feed de Bob, Bob baixa o log de feed de Alice. Bob pode verificar se o registro do feed realmente pertence a Alice verificando as assinaturas.

GUI - Interface Gráfica do Utilizador(Usuário)

Patchwork - Uma GUI SSB (Descontinuado)

Patchwork é o aplicativo de mensagens e compartilhamento descentralizado construído em cima do SSB . O protocolo scuttlebutt em si não mantém um conjunto de feeds nos quais um usuário está interessado, então um cliente é necessário para manter uma lista de feeds de pares em que seu respectivo usuário está interessado e seguindo.

Fonte: scuttlebutt.nz

Quando você instala e executa o Patchwork, você só pode ver e se comunicar com seus pares em sua rede local. Para acessar fora de sua LAN, você precisa se conectar a um Pub. Um pub é apenas para convidados e eles retransmitem mensagens entre você e seus pares fora de sua LAN e entre outros Pubs.

Lembre-se de que você precisa seguir alguém para receber mensagens dessa pessoa. Isso reduz o envio de mensagens de spam para os usuários. Os usuários só veem as respostas das pessoas que seguem. Os dados são sincronizados no disco para funcionar offline, mas podem ser sincronizados diretamente com os pares na sua LAN por wi-fi ou bluetooth.

Patchbay - Uma GUI Alternativa

Patchbay é um cliente de fofoca projetado para ser fácil de modificar e estender. Ele usa o mesmo banco de dados que Patchwork e Patchfoo , então você pode facilmente dar uma volta com sua identidade existente.

Planetary - GUI para IOS

Planetary é um app com pubs pré-carregados para facilitar integração.

Manyverse - GUI para Android

Manyverse é um aplicativo de rede social com recursos que você esperaria: posts, curtidas, perfis, mensagens privadas, etc. Mas não está sendo executado na nuvem de propriedade de uma empresa, em vez disso, as postagens de seus amigos e todos os seus dados sociais vivem inteiramente em seu telefone .

VaultApi a self-host method for securing data

VaultApi is dependent upon both HashiCorp Vault and VeraCrypt to work it's magic.

Hashicorp Vault and KeePassXC are the primary password manager applications that I'm using currently and for the most part the entries in each should be mirroring each other. The functional difference between these two are KeePassXC has a graphical interface. While Hashicorp Vault has a web interface, the key value VaultApi makes use of is the REST Api to perform ACID operations on secured data for automation purposes.

The vault keys and root token associated with HashiCorp Vault are stored in an encrypted file that is kept in cold storage. Prior to starting HashiCrop Vault server, the cold storage file is mounted on the system using VeraCrypt.

Also, this implementation is on my non-routed network primarily being used by my Linux systems but any OS supporting PowerShell on the non-routed network should be able to access the Vault as a client.

Additionally, the Vault is only ran on an on-demand basis.

The startup process is as follows: VaultApi start VaultApi unseal VaultApi login VaultApi KeyPaths The command VaultApi KeyPaths dumps a list of key paths to a local file to make the finding of key paths simpler.

The path lookup process is as follows: VaultApi FindPaths Vehicle This command returns a list of paths matching the specified value of Vehicle. VaultApi FindPaths Vehicle kv1/Vehicle/1995-Mustang-GT500 kv1/Vehicle/2003-DodgeViper kv1/Vehicle/2012-Nissan kv1/Vehicle/2016-Telsa To lookup all the keys associated to a given path: VaultApi kv1Read kv1/Vehicle/2012-Nissan -kvkey _ReturnKeys plate VIN To return a value associated with a key of a given path to the clipboard: VaultApi kv1Read kv1/Vehicle/2012-Nissan -kvkey plate If the -raw options is included the value will be returned to the console.

To add a new key/value pair to an existing path: VaultApi kv1Update kv1/Vehicle/2012-Nissan 21000000 -kvkey mileage To add a new path and key/value pair: VaultApi kv1Create kv1/Vehicle/2025-Lambo Bitcoin -kvkey plate To list the 2nd level path names: ``` Default level 1 path name is "kv1"

VaultApi kv1list

To list 3rd level path names:

VaultApi kv1list kv1/Vehicle To Delete a **path** and it's associated key/value pairs: VaultApi kv1Delete kv1/Vehicle/2012-Nissan

To just delete a single key/value pair for a given path use the HashiCorp Vault Web interface. To launch the **HashiCorp Vault** web interface: VaultApi WebUI To return status information about the **Vault**: VaultApi status sealed initialized version n t

---

False True 1.15.6 5 3

To return process information about the **Vault**: VaultApi Check Hashicorp Vault (v1.15.6) is running...116147 ``` To show the hash value of the VaultApi script:

VaultApi ShowHash 3D47628ECB3FA0E7DBD28BA7606CE5BF To return a 20 character randomized value to the clipboard: VaultApi SetValue To create a backup of the HashiCorp Vault : ``` Must be logged in with the root token.

VaultApi Backup

A snapshot file will be created in the $HOME/Downloads directory by default. ``` To stop the HashiCorp Vault server:

``` VaultApi seal The vault is sealed.

VaultApi stop The server is stopped.

```

NIPs

Allow multi-user AUTH #1881 vitorpamplona is proposing a PR that reuses one connection for everyone by accepting multi-user logins on the relay side. Additionally, this PR standardizes how relays should handle multiple AUTH messages from the client, instead of leaving it as undefined behavior. Currently, most relays override the previous AUTH, which means developers can rotate the authenticated user within the same connection. Some relays only accept the first AUTH and ignore the rest. A few newer relays already support multi-user logins as described in this PR, which he believes is the correct way to implement NIP-42 AUTH. The purpose of this PR is to formalize that behavior.

Adds optional nip60.signSecret() and kind 10019 filter tag #1890 robwoodgate is proposing a PR that clarifies and improves Nostr <---> Cashu interoperability as follows:Adds an optional signer signature for NUT-10 well-known secrets to NIP-60, NIP-07 and NIP-46；Clarifies use of Nostr <---> Cashu public keys in NIP-61；Adds an optional reverse lookup filter tag to NIP-61 kind 10019 events.

I heard the regular polls are saying The liberals were ahead of conservatives so I decided to run my own mini-poll to see for myself or at least have a second opinion, then I find this: I am not saying this represents the 40Million+ people who live in Canada but neither the legacy polls. I encourage everyone do their own mini-poll for themselves to find out themselves, don't trust verify".

Last year same thing happened in the U.S. election, the polls were saying Kamala is on the lead over Trump but Trump ended up winning in a landslide.

Último dia do ano, momento para tirar o pó da bola de cristal, para fazer reflexões, previsões e desejos para o próximo ano e seguintes.

Ano após ano, o Bitcoin evoluiu, foi ultrapassando etapas, tornou-se cada vez mais mainstream. Está cada vez mais difícil fazer previsões sobre o Bitcoin, já faltam poucas barreiras a serem ultrapassadas e as que faltam são altamente complexas ou tem um impacto profundo no sistema financeiro ou na sociedade. Estas alterações profundas tem que ser realizadas lentamente, porque uma alteração rápida poderia resultar em consequências terríveis, poderia provocar um retrocesso.

Código do Bitcoin

No final de 2025, possivelmente vamos ter um fork, as discussões sobre os covenants já estão avançadas, vão acelerar ainda mais. Já existe um consenso relativamente alto, a favor dos covenants, só falta decidir que modelo será escolhido. Penso que até ao final do ano será tudo decidido.

Depois dos covenants, o próximo foco será para a criptografia post-quantum, que será o maior desafio que o Bitcoin enfrenta. Criar uma criptografia segura e que não coloque a descentralização em causa.

Espero muito de Ark, possivelmente a inovação do ano, gostaria de ver o Nostr a furar a bolha bitcoinheira e que o Cashu tivesse mais reconhecimento pelos bitcoiners.

Espero que surjam avanços significativos no BitVM2 e BitVMX.

Não sei o que esperar das layer 2 de Bitcoin, foram a maior desilusão de 2024. Surgiram com muita força, mas pouca coisa saiu do papel, foi uma mão cheia de nada. Uma parte dos projetos caiu na tentação da shitcoinagem, na criação de tokens, que tem um único objetivo, enriquecer os devs e os VCs.

Se querem ser levados a sério, têm que ser sérios.

“À mulher de César não basta ser honesta, deve parecer honesta”

Se querem ter o apoio dos bitcoiners, sigam o ethos do Bitcoin.

Neste ponto a atitude do pessoal da Ark é exemplar, em vez de andar a chorar no Twitter para mudar o código do Bitcoin, eles colocaram as mãos na massa e criaram o protocolo. É claro que agora está meio “coxo”, funciona com uma multisig ou com os covenants na Liquid. Mas eles estão a criar um produto, vão demonstrar ao mercado que o produto é bom e útil. Com a adoção, a comunidade vai perceber que o Ark necessita dos covenants para melhorar a interoperabilidade e a soberania.

É este o pensamento certo, que deveria ser seguido pelos restantes e futuros projetos. É seguir aquele pensamento do J.F. Kennedy:

“Não perguntem o que é que o vosso país pode fazer por vocês, perguntem o que é que vocês podem fazer pelo vosso país”

Ou seja, não fiquem à espera que o bitcoin mude, criem primeiro as inovações/tecnologia, ganhem adoção e depois demonstrem que a alteração do código camada base pode melhorar ainda mais o vosso projeto. A necessidade é que vai levar a atualização do código.

Reservas Estratégicas de Bitcoin

Bancos centrais

Com a eleição de Trump, emergiu a ideia de uma Reserva Estratégia de Bitcoin, tornou este conceito mainstream. Foi um pivot, a partir desse momento, foram enumerados os políticos de todo o mundo a falar sobre o assunto.

A Senadora Cynthia Lummis foi mais além e propôs um programa para adicionar 200 mil bitcoins à reserva ao ano, até 1 milhão de Bitcoin. Só que isto está a criar uma enorme expectativa na comunidade, só que pode resultar numa enorme desilusão. Porque no primeiro ano, o Trump em vez de comprar os 200 mil, pode apenas adicionar na reserva, os 198 mil que o Estado já tem em sua posse. Se isto acontecer, possivelmente vai resultar numa forte queda a curto prazo. Na minha opinião os bancos centrais deveriam seguir o exemplo de El Salvador, fazer um DCA diário.

Mais que comprar bitcoin, para mim, o mais importante é a criação da Reserva, é colocar o Bitcoin ao mesmo nível do ouro, o impacto para o resto do mundo será tremendo, a teoria dos jogos na sua plenitude. Muitos outros bancos centrais vão ter que comprar, para não ficarem atrás, além disso, vai transmitir uma mensagem à generalidade da população, que o Bitcoin é “afinal é algo seguro, com valor”.

Mas não foi Trump que iniciou esta teoria dos jogos, mas sim foi a primeira vítima dela. É o próprio Trump que o admite, que os EUA necessitam da reserva para não ficar atrás da China. Além disso, desde que os EUA utilizaram o dólar como uma arma, com sanção contra a Rússia, surgiram boatos de que a Rússia estaria a utilizar o Bitcoin para transações internacionais. Que foram confirmados recentemente, pelo próprio governo russo. Também há poucos dias, ainda antes deste reconhecimento público, Putin elogiou o Bitcoin, ao reconhecer que “Ninguém pode proibir o bitcoin”, defendendo como uma alternativa ao dólar. A narrativa está a mudar.

Já existem alguns países com Bitcoin, mas apenas dois o fizeram conscientemente (El Salvador e Butão), os restantes têm devido a apreensões. Hoje são poucos, mas 2025 será o início de uma corrida pelos bancos centrais. Esta corrida era algo previsível, o que eu não esperava é que acontecesse tão rápido.

Empresas

A criação de reservas estratégicas não vai ficar apenas pelos bancos centrais, também vai acelerar fortemente nas empresas em 2025.

Mas as empresas não vão seguir a estratégia do Saylor, vão comprar bitcoin sem alavancagem, utilizando apenas os tesouros das empresas, como uma proteção contra a inflação. Eu não sou grande admirador do Saylor, prefiro muito mais, uma estratégia conservadora, sem qualquer alavancagem. Penso que as empresas vão seguir a sugestão da BlackRock, que aconselha um alocações de 1% a 3%.

Penso que 2025, ainda não será o ano da entrada das 6 magníficas (excepto Tesla), será sobretudo empresas de pequena e média dimensão. As magníficas ainda tem uma cota muito elevada de shareholders com alguma idade, bastante conservadores, que têm dificuldade em compreender o Bitcoin, foi o que aconteceu recentemente com a Microsoft.

Também ainda não será em 2025, talvez 2026, a inclusão nativamente de wallet Bitcoin nos sistema da Apple Pay e da Google Pay. Seria um passo gigante para a adoção a nível mundial.

ETFs

Os ETFs para mim são uma incógnita, tenho demasiadas dúvidas, como será 2025. Este ano os inflows foram superiores a 500 mil bitcoins, o IBIT foi o lançamento de ETF mais bem sucedido da história. O sucesso dos ETFs, deve-se a 2 situações que nunca mais se vão repetir. O mercado esteve 10 anos à espera pela aprovação dos ETFs, a procura estava reprimida, isso foi bem notório nos primeiros meses, os inflows foram brutais.

Também se beneficiou por ser um mercado novo, não existia orderbook de vendas, não existia um mercado interno, praticamente era só inflows. Agora o mercado já estabilizou, a maioria das transações já são entre clientes dos próprios ETFs. Agora só uma pequena percentagem do volume das transações diárias vai resultar em inflows ou outflows.

Estes dois fenómenos nunca mais se vão repetir, eu não acredito que o número de inflows em BTC supere os número de 2024, em dólares vai superar, mas em btc não acredito que vá superar.

Mas em 2025 vão surgir uma infindável quantidade de novos produtos, derivativos, novos ETFs de cestos com outras criptos ou cestos com ativos tradicionais. O bitcoin será adicionado em produtos financeiros já existentes no mercado, as pessoas vão passar a deter bitcoin, sem o saberem.

Com o fim da operação ChokePoint 2.0, vai surgir uma nova onda de adoção e de produtos financeiros. Possivelmente vamos ver bancos tradicionais a disponibilizar produtos ou serviços de custódia aos seus clientes.

Eu adoraria ver o crescimento da adoção do bitcoin como moeda, só que a regulamentação não vai ajudar nesse processo.

Preço

Eu acredito que o topo deste ciclo será alcançado no primeiro semestre, posteriormente haverá uma correção. Mas desta vez, eu acredito que a correção será muito menor que as anteriores, inferior a 50%, esta é a minha expectativa. Espero estar certo.

Stablecoins de dólar

Agora saindo um pouco do universo do Bitcoin, acho importante destacar as stablecoins.

No último ciclo, eu tenho dividido o tempo, entre continuar a estudar o Bitcoin e estudar o sistema financeiro, as suas dinâmicas e o comportamento humano. Isto tem sido o meu foco de reflexão, imaginar a transformação que o mundo vai sofrer devido ao padrão Bitcoin. É uma ilusão acreditar que a transição de um padrão FIAT para um padrão Bitcoin vai ser rápida, vai existir um processo transitório que pode demorar décadas.

Com a re-entrada de Trump na Casa Branca, prometendo uma política altamente protecionista, vai provocar uma forte valorização do dólar, consequentemente as restantes moedas do mundo vão derreter. Provocando uma inflação generalizada, gerando uma corrida às stablecoins de dólar nos países com moedas mais fracas. Trump vai ter uma política altamente expansionista, vai exportar dólares para todo o mundo, para financiar a sua própria dívida. A desigualdade entre os pobres e ricos irá crescer fortemente, aumentando a possibilidade de conflitos e revoltas.

“Casa onde não há pão, todos ralham e ninguém tem razão”

Será mais lenha, para alimentar a fogueira, vai gravar os conflitos geopolíticos já existentes, ficando as sociedade ainda mais polarizadas.

Eu acredito que 2025, vai haver um forte crescimento na adoção das stablecoins de dólares, esse forte crescimento vai agravar o problema sistémico que são as stablecoins. Vai ser o início do fim das stablecoins, pelo menos, como nós conhecemos hoje em dia.

Problema sistémico

O sistema FIAT não nasceu de um dia para outro, foi algo que foi construído organicamente, ou seja, foi evoluindo ao longo dos anos, sempre que havia um problema/crise, eram criadas novas regras ou novas instituições para minimizar os problemas. Nestes quase 100 anos, desde os acordos de Bretton Woods, a evolução foram tantas, tornaram o sistema financeiro altamente complexo, burocrático e nada eficiente.

Na prática é um castelo de cartas construído sobre outro castelo de cartas e que por sua vez, foi construído sobre outro castelo de cartas.

As stablecoins são um problema sistémico, devido às suas reservas em dólares e o sistema financeiro não está preparado para manter isso seguro. Com o crescimento das reservas ao longo dos anos, foi se agravando o problema.

No início a Tether colocava as reservas em bancos comerciais, mas com o crescimento dos dólares sob gestão, criou um problema nos bancos comerciais, devido à reserva fracionária. Essas enormes reservas da Tether estavam a colocar em risco a própria estabilidade dos bancos.

A Tether acabou por mudar de estratégia, optou por outros ativos, preferencialmente por títulos do tesouro/obrigações dos EUA. Só que a Tether continua a crescer e não dá sinais de abrandamento, pelo contrário.

Até o próprio mundo cripto, menosprezava a gravidade do problema da Tether/stablecoins para o resto do sistema financeiro, porque o marketcap do cripto ainda é muito pequeno. É verdade que ainda é pequeno, mas a Tether não o é, está no top 20 dos maiores detentores de títulos do tesouros dos EUA e está ao nível dos maiores bancos centrais do mundo. Devido ao seu tamanho, está a preocupar os responsáveis/autoridades/reguladores dos EUA, pode colocar em causa a estabilidade do sistema financeiro global, que está assente nessas obrigações.

Os títulos do tesouro dos EUA são o colateral mais utilizado no mundo, tanto por bancos centrais, como por empresas, é a charneira da estabilidade do sistema financeiro. Os títulos do tesouro são um assunto muito sensível. Na recente crise no Japão, do carry trade, o Banco Central do Japão tentou minimizar a desvalorização do iene através da venda de títulos dos EUA. Esta operação, obrigou a uma viagem de emergência, da Secretaria do Tesouro dos EUA, Janet Yellen ao Japão, onde disponibilizou liquidez para parar a venda de títulos por parte do Banco Central do Japão. Essa forte venda estava desestabilizando o mercado.

Os principais detentores de títulos do tesouros são institucionais, bancos centrais, bancos comerciais, fundo de investimento e gestoras, tudo administrado por gestores altamente qualificados, racionais e que conhecem a complexidade do mercado de obrigações.

O mundo cripto é seu oposto, é naife com muita irracionalidade e uma forte pitada de loucura, na sua maioria nem faz a mínima ideia como funciona o sistema financeiro. Essa irracionalidade pode levar a uma “corrida bancária”, como aconteceu com o UST da Luna, que em poucas horas colapsou o projeto. Em termos de escala, a Luna ainda era muito pequena, por isso, o problema ficou circunscrito ao mundo cripto e a empresas ligadas diretamente ao cripto.

Só que a Tether é muito diferente, caso exista algum FUD, que obrigue a Tether a desfazer-se de vários biliões ou dezenas de biliões de dólares em títulos num curto espaço de tempo, poderia provocar consequências terríveis em todo o sistema financeiro. A Tether é grande demais, é já um problema sistémico, que vai agravar-se com o crescimento em 2025.

Não tenham dúvidas, se existir algum problema, o Tesouro dos EUA vai impedir a venda dos títulos que a Tether tem em sua posse, para salvar o sistema financeiro. O problema é, o que vai fazer a Tether, se ficar sem acesso às venda das reservas, como fará o redeem dos dólares?

Como o crescimento do Tether é inevitável, o Tesouro e o FED estão com um grande problema em mãos, o que fazer com o Tether?

Mas o problema é que o atual sistema financeiro é como um curto cobertor: Quanto tapas a cabeça, destapas os pés; Ou quando tapas os pés, destapas a cabeça. Ou seja, para resolver o problema da guarda reservas da Tether, vai criar novos problemas, em outros locais do sistema financeiro e assim sucessivamente.

Conta mestre

Uma possível solução seria dar uma conta mestre à Tether, dando o acesso direto a uma conta no FED, semelhante à que todos os bancos comerciais têm. Com isto, a Tether deixaria de necessitar os títulos do tesouro, depositando o dinheiro diretamente no banco central. Só que isto iria criar dois novos problemas, com o Custodia Bank e com o restante sistema bancário.

O Custodia Bank luta há vários anos contra o FED, nos tribunais pelo direito a ter licença bancária para um banco com full-reserves. O FED recusou sempre esse direito, com a justificativa que esse banco, colocaria em risco toda a estabilidade do sistema bancário existente, ou seja, todos os outros bancos poderiam colapsar. Perante a existência em simultâneo de bancos com reserva fracionária e com full-reserves, as pessoas e empresas iriam optar pelo mais seguro. Isso iria provocar uma corrida bancária, levando ao colapso de todos os bancos com reserva fracionária, porque no Custodia Bank, os fundos dos clientes estão 100% garantidos, para qualquer valor. Deixaria de ser necessário limites de fundos de Garantia de Depósitos.

Eu concordo com o FED nesse ponto, que os bancos com full-reserves são uma ameaça a existência dos restantes bancos. O que eu discordo do FED, é a origem do problema, o problema não está nos bancos full-reserves, mas sim nos que têm reserva fracionária.

O FED ao conceder uma conta mestre ao Tether, abre um precedente, o Custodia Bank irá o aproveitar, reclamando pela igualdade de direitos nos tribunais e desta vez, possivelmente ganhará a sua licença.

Ainda há um segundo problema, com os restantes bancos comerciais. A Tether passaria a ter direitos similares aos bancos comerciais, mas os deveres seriam muito diferentes. Isto levaria os bancos comerciais aos tribunais para exigir igualdade de tratamento, é uma concorrência desleal. Isto é o bom dos tribunais dos EUA, são independentes e funcionam, mesmo contra o estado. Os bancos comerciais têm custos exorbitantes devido às políticas de compliance, como o KYC e AML. Como o governo não vai querer aliviar as regras, logo seria a Tether, a ser obrigada a fazer o compliance dos seus clientes.

A obrigação do KYC para ter stablecoins iriam provocar um terramoto no mundo cripto.

Assim, é pouco provável que seja a solução para a Tether.

FED

Só resta uma hipótese, ser o próprio FED a controlar e a gerir diretamente as stablecoins de dólar, nacionalizado ou absorvendo as existentes. Seria uma espécie de CBDC. Isto iria provocar um novo problema, um problema diplomático, porque as stablecoins estão a colocar em causa a soberania monetária dos outros países. Atualmente as stablecoins estão um pouco protegidas porque vivem num limbo jurídico, mas a partir do momento que estas são controladas pelo governo americano, tudo muda. Os países vão exigir às autoridades americanas medidas que limitem o uso nos seus respectivos países.

Não existe uma solução boa, o sistema FIAT é um castelo de cartas, qualquer carta que se mova, vai provocar um desmoronamento noutro local. As autoridades não poderão adiar mais o problema, terão que o resolver de vez, senão, qualquer dia será tarde demais. Se houver algum problema, vão colocar a responsabilidade no cripto e no Bitcoin. Mas a verdade, a culpa é inteiramente dos políticos, da sua incompetência em resolver os problemas a tempo.

Será algo para acompanhar futuramente, mas só para 2026, talvez…

É curioso, há uns anos pensava-se que o Bitcoin seria a maior ameaça ao sistema ao FIAT, mas afinal, a maior ameaça aos sistema FIAT é o próprio FIAT(stablecoins). A ironia do destino.

Isto é como uma corrida, o Bitcoin é aquele atleta que corre ao seu ritmo, umas vezes mais rápido, outras vezes mais lento, mas nunca pára. O FIAT é o atleta que dá tudo desde da partida, corre sempre em velocidade máxima. Só que a vida e o sistema financeiro não é uma prova de 100 metros, mas sim uma maratona.

Europa

2025 será um ano desafiante para todos europeus, sobretudo devido à entrada em vigor da regulamentação (MiCA). Vão começar a sentir na pele a regulamentação, vão agravar-se os problemas com os compliance, problemas para comprovar a origem de fundos e outras burocracias. Vai ser lindo.

O Travel Route passa a ser obrigatório, os europeus serão obrigados a fazer o KYC nas transações. A Travel Route é uma suposta lei para criar mais transparência, mas prática, é uma lei de controle, de monitorização e para limitar as liberdades individuais dos cidadãos.

O MiCA também está a colocar problemas nas stablecoins de Euro, a Tether para já preferiu ficar de fora da europa. O mais ridículo é que as novas regras obrigam os emissores a colocar 30% das reservas em bancos comerciais. Os burocratas europeus não compreendem que isto coloca em risco a estabilidade e a solvência dos próprios bancos, ficam propensos a corridas bancárias.

O MiCA vai obrigar a todas as exchanges a estar registadas em solo europeu, ficando vulnerável ao temperamento dos burocratas. Ainda não vai ser em 2025, mas a UE vai impor políticas de controle de capitais, é inevitável, as exchanges serão obrigadas a usar em exclusividade stablecoins de euro, as restantes stablecoins serão deslistadas.

Todas estas novas regras do MiCA, são extremamente restritas, não é para garantir mais segurança aos cidadãos europeus, mas sim para garantir mais controle sobre a população. A UE está cada vez mais perto da autocracia, do que da democracia. A minha única esperança no horizonte, é que o sucesso das políticas cripto nos EUA, vai obrigar a UE a recuar e a aligeirar as regras, a teoria dos jogos é implacável. Mas esse recuo, nunca acontecerá em 2025, vai ser um longo período conturbado.

Recessão

Os mercados estão todos em máximos históricos, isto não é sustentável por muito tempo, suspeito que no final de 2025 vai acontecer alguma correção nos mercados. A queda só não será maior, porque os bancos centrais vão imprimir dinheiro, muito dinheiro, como se não houvesse amanhã. Vão voltar a resolver os problemas com a injeção de liquidez na economia, é empurrar os problemas com a barriga, em de os resolver. Outra vez o efeito Cantillon.

Será um ano muito desafiante a nível político, onde o papel dos políticos será fundamental. A crise política na França e na Alemanha, coloca a UE órfã, sem um comandante ao leme do navio. 2025 estará condicionado pelas eleições na Alemanha, sobretudo no resultado do AfD, que podem colocar em causa a propriedade UE e o euro.

Possivelmente, só o fim da guerra poderia minimizar a crise, algo que é muito pouco provável acontecer.

Em Portugal, a economia parece que está mais ou menos equilibrada, mas começam a aparecer alguns sinais preocupantes. Os jogos de sorte e azar estão em máximos históricos, batendo o recorde de 2014, época da grande crise, não é um bom sinal, possivelmente já existe algum desespero no ar.

A Alemanha é o motor da Europa, quanto espirra, Portugal constipa-se. Além do problema da Alemanha, a Espanha também está à beira de uma crise, são os países que mais influenciam a economia portuguesa.

Se existir uma recessão mundial, terá um forte impacto no turismo, que é hoje em dia o principal motor de Portugal.

Brasil

Brasil é algo para acompanhar em 2025, sobretudo a nível macro e a nível político. Existe uma possibilidade de uma profunda crise no Brasil, sobretudo na sua moeda. O banco central já anda a queimar as reservas para minimizar a desvalorização do Real.

Sem mudanças profundas nas políticas fiscais, as reservas vão se esgotar. As políticas de controle de capitais são um cenário plausível, será interesse de acompanhar, como o governo irá proceder perante a existência do Bitcoin e stablecoins. No Brasil existe um forte adoção, será um bom case study, certamente irá repetir-se em outros países num futuro próximo.

Os próximos tempos não serão fáceis para os brasileiros, especialmente para os que não têm Bitcoin.

Blockchain

Em 2025, possivelmente vamos ver os primeiros passos da BlackRock para criar a primeira bolsa de valores, exclusivamente em blockchain. Eu acredito que a BlackRock vai criar uma própria blockchain, toda controlada por si, onde estarão os RWAs, para fazer concorrência às tradicionais bolsas de valores. Será algo interessante de acompanhar.

---

Estas são as minhas previsões, eu escrevi isto muito em cima do joelho, certamente esqueci-me de algumas coisas, se for importante acrescentarei nos comentários. A maioria das previsões só acontecerá após 2025, mas fica aqui a minha opinião.

Isto é apenas a minha opinião, Don’t Trust, Verify!

@ de6c63ab:d028389b

Honestly, I didn’t think this would still be a thing in 2025, but every once in a while it pops up again:

“Bitcoin? Uh, I don’t know… but blockchain, now that could be useful! 🤌”

“Blockchain is one of the most important technologies of our time. Maybe you know it from crypto, but it’s so much more. It’s a way to store and verify data securely, transparently, and without a middleman. That’s why it’s going to revolutionize banking, healthcare, logistics, and even government!”

“Blockchain is transforming how we store, share, and verify information. Its benefits go far beyond cryptocurrencies. Understanding it today means preparing for tomorrow, because blockchain is guaranteed to play a major role in the future.”

Blockchain

When people say "blockchain," they usually mean the bitcoin database — with all its unique properties — even when they’re imagining using it elsewhere.

But here’s the thing: blockchain by itself isn’t some revolutionary breakthrough.
Stripped from bitcoin, it’s just a fancy list of records, each pointing to the previous one with a reference (typically a hash).
That's it.

This idea — chaining data together — isn’t new.
It goes back to at least 1991, when Haber and Stornetta proposed it for timestamping documents.

By itself, blockchain isn’t secure (you can always rewrite past records if you recompute the chain), isn’t necessarily transparent (the data can be encrypted or hidden), and doesn't magically remove the need for trust (if someone logs soccer scores into a blockchain, you still have to trust they reported the results honestly).

What actually makes bitcoin’s blockchain secure and trustworthy is the system around it — the economic incentives, the ruthless competition for block rights, and the distributed consensus mechanics.

Without those, blockchain is just another database.

---

How Does Bitcoin Make It Work?

To understand why, we need to zoom in a little.

Superficially, bitcoin’s blockchain looks like a simple ledger — a record of transactions grouped into blocks. A transaction means someone spent bitcoin — unlocking it and locking it up again for someone else.

But here’s the key:
Every participant can independently verify whether each transaction is valid, with no outside help and no trust required.

Think of every transaction like a math equation.
Something like: x + 7 = 5, with the solution x = -2.
You don’t need anyone to tell you if it’s correct — you can check it yourself.

Of course, bitcoin’s equations are far more complex.
They involve massive numbers and strange algebraic structures, where solving without the right key is practically impossible, but verifying a solution is easy.

This is why only someone with the private key can authorize a transaction.

In a way, "solving" these equations is how you prove your right to spend bitcoin.
Ownership and transfers are purely a matter of internal system math — no external authority needed.

---

Could We Use Blockchain for Other Stuff?

Could we use a blockchain to independently verify medical records, soccer scores, or property ownership?

No.

Blockchain can't magically calculate whether you broke your arm, whether Real Madrid tied against Barcelona, or who owns a cottage in some village.

It can verify that someone owns bitcoin at a particular address, because that's just solving equations inside the system.

But anything that depends on outside facts?
Blockchain can't help you there.

---

Why Does Everyone Stick to One Version?

Another big question:
Why do people in bitcoin agree on the same version of history?

Because of proof-of-work.

To add a new block, you have to find a specific giant number — the nonce — that, together with the block’s contents, satisfies a predefined condition.

You can't calculate the nonce directly — you have to guess, billions of times per second, until you hit the jackpot.
It takes minutes of relentless effort.

An invalid transaction would invalidate the entire block, wasting all the miner’s effort.

If the block is valid, the miner earns a reward — newly minted bitcoins plus transaction fees — making the massive effort worthwhile.

And importantly, because each block is built on top of all previous ones, rewriting history would mean redoing all the proof-of-work from that point forward — an astronomically expensive and practically impossible task.
The deeper a block is buried under newer blocks, the more secure it becomes — making the past effectively immutable.

And again: each node independently verifies all transactions.
Miners don't create truth; they race to package and timestamp already-valid transactions.
The winning chain is simply the one with the most provable work behind it.

---

Bitcoin and Blockchain: Inseparable

Bitcoin is created on the blockchain — and it exists only within the blockchain.
Ownership is defined by it.
The decentralized management of the blockchain is driven by bitcoin incentives — the pursuit of something scarce, hard-earned, and impossible to fake.

No blockchain, no bitcoin.
No bitcoin, no meaningful blockchain.

---

Can We Just Blockchain Everything?

Alright, so what happens if we try to apply this system to something else — say, a land registry?

Properties themselves don’t "exist" on a blockchain — only claims about them can be recorded.

But who writes the claims? Random miners?
Where do they get their information?
They can’t compute it from previous blocks.
They’d have to physically go check who owns what.

What if they’re lazy? Lied to? Made mistakes?
How would anyone else verify the records?
Ownership in the physical world isn’t a problem you can solve by crunching numbers in a database.

Suddenly, we’re right back to needing trusted third parties — the very thing blockchain was supposed to eliminate.

And if there’s a dispute?
Say someone refuses to leave a house, claiming they've lived there forever.
Is the blockchain going to show up and evict them?

Of course not.

---

Blockchain Without Bitcoin Is Just a Data Structure

And that’s the difference.

When blockchain is part of bitcoin’s closed system, it works because everything it cares about is internal and verifiable.

When you try to export blockchain into the real world — without bitcoin — it loses its magic.

Blockchain-like structures actually exist elsewhere too — take Git, for example.
It’s a chain of commits, each referencing the previous one by its hash.
It chains data like a blockchain does — but without the security, decentralization, or economic meaning behind bitcoin.

Blockchain is just a data structure.
Bitcoin is what gives it meaning.

In bitcoin, the blockchain is not just a ledger — it's a trustless system of property rights enforced by math and energy, without any central authority.

Fiduciary duty is the obligation to act in the client’s best interests at all times, prioritizing their needs above the advisor’s own, ensuring honesty, transparency, and avoiding conflicts of interest in all recommendations and actions.

This is something all advisors in the BFAN take very seriously; after all, we are legally required to do so. For the average advisor this is a fairly easy box to check. All you essentially have to do is have someone take a 5-minute risk assessment, fill out an investment policy statement, and then throw them in the proverbial 60/40 portfolio. You have thousands of investment options to choose from and you can reasonably explain how your client is theoretically insulated from any move in the \~markets\~. From the traditional financial advisor perspective, you could justify nearly anything by putting a client into this type of portfolio. All your bases were pretty much covered from return profile, regulatory, compliance, investment options, etc. It was just too easy. It became the household standard and now a meme.

As almost every real bitcoiner knows, the 60/40 portfolio is moving into psyop territory, and many financial advisors get clowned on for defending this relic on bitcoin twitter. I’m going to specifically poke fun at the ‘40’ part of this portfolio.

The ‘40’ represents fixed income, defined as…

An investment type that provides regular, set interest payments, such as bonds or treasury securities, and returns the principal at maturity. It’s generally considered a lower-risk asset class, used to generate stable income and preserve capital.

Historically, this part of the portfolio was meant to weather the volatility in the equity markets and represent the “safe” investments. Typically, some sort of bond.

First and foremost, the fixed income section is most commonly constructed with U.S. Debt. There are a couple main reasons for this. Most financial professionals believe the same fairy tale that U.S. Debt is “risk free” (lol). U.S. debt is also one of the largest and most liquid assets in the market which comes with a lot of benefits.

There are many brilliant bitcoiners in finance and economics that have sounded the alarm on the U.S. debt ticking time bomb. I highly recommend readers explore the work of Greg Foss, Lawrence Lepard, Lyn Alden, and Saifedean Ammous. My very high-level recap of their analysis:

• A bond is a contract in which Party A (the borrower) agrees to repay Party B (the lender) their principal plus interest over time.

• The U.S. government issues bonds (Treasury securities) to finance its operations after tax revenues have been exhausted.

• These are traditionally viewed as “risk-free” due to the government’s historical reliability in repaying its debts and the strength of the U.S. economy

• U.S. bonds are seen as safe because the government has control over the dollar (world reserve asset) and, until recently (20 some odd years), enjoyed broad confidence that it would always honor its debts.

• This perception has contributed to high global demand for U.S. debt but, that is quickly deteriorating.

• The current debt situation raises concerns about sustainability.

• The U.S. has substantial obligations, and without sufficient productivity growth, increasing debt may lead to a cycle where borrowing to cover interest leads to more debt.

• This could result in more reliance on money creation (printing), which can drive inflation and further debt burdens.

In the words of Lyn Alden “Nothing stops this train”

Those obligations are what makes up the 40% of most the fixed income in your portfolio. So essentially you are giving money to one of the worst capital allocators in the world (U.S. Gov’t) and getting paid back with printed money.

As someone who takes their fiduciary responsibility seriously and understands the debt situation we just reviewed, I think it’s borderline negligent to put someone into a classic 60% (equities) / 40% (fixed income) portfolio without serious scrutiny of the client’s financial situation and options available to them. I certainly have my qualms with equities at times, but overall, they are more palatable than the fixed income portion of the portfolio. I don’t like it either, but the money is broken and the unit of account for nearly every equity or fixed income instrument (USD) is fraudulent. It’s a paper mache fade that is quite literally propped up by the money printer.

To briefly be as most charitable as I can – It wasn’t always this way. The U.S. Dollar used to be sound money, we used to have government surplus instead of mathematically certain deficits, The U.S. Federal Government didn’t used to have a money printing addiction, and pre-bitcoin the 60/40 portfolio used to be a quality portfolio management strategy. Those times are gone.

Now the fun part. How does bitcoin fix this?

Bitcoin fixes this indirectly. Understanding investment criteria changes via risk tolerance, age, goals, etc. A client may still have a need for “fixed income” in the most literal definition – Low risk yield. Now you may be thinking that yield is a bad word in bitcoin land, you’re not wrong, so stay with me. Perpetual motion machine crypto yield is fake and largely where many crypto scams originate. However, that doesn’t mean yield in the classic finance sense does not exist in bitcoin, it very literally does. Fortunately for us bitcoiners there are many other smart, driven, and enterprising bitcoiners that understand this problem and are doing something to address it. These individuals are pioneering new possibilities in bitcoin and finance, specifically when it comes to fixed income.

Here are some new developments –

Private Credit Funds – The Build Asset Management Secured Income Fund I is a private credit fund created by Build Asset Management. This fund primarily invests in bitcoin-backed, collateralized business loans originated by Unchained, with a secured structure involving a multi-signature, over-collateralized setup for risk management. Unchained originates loans and sells them to Build, which pools them into the fund, enabling investors to share in the interest income.

Dynamics

• Loan Terms: Unchained issues loans at interest rates around 14%, secured with a 2/3 multi-signature vault backed by a 40% loan-to-value (LTV) ratio.
• Fund Mechanics: Build buys these loans from Unchained, thus providing liquidity to Unchained for further loan originations, while Build manages interest payments to investors in the fund.

Pros

• The fund offers a unique way to earn income via bitcoin-collateralized debt, with protection against rehypothecation and strong security measures, making it attractive for investors seeking exposure to fixed income with bitcoin.

Cons

• The fund is only available to accredited investors, which is a regulatory standard for private credit funds like this.

Corporate Bonds – MicroStrategy Inc. (MSTR), a business intelligence company, has leveraged its corporate structure to issue bonds specifically to acquire bitcoin as a reserve asset. This approach allows investors to indirectly gain exposure to bitcoin’s potential upside while receiving interest payments on their bond investments. Some other publicly traded companies have also adopted this strategy, but for the sake of this article we will focus on MSTR as they are the biggest and most vocal issuer.

Dynamics

• Issuance: MicroStrategy has issued senior secured notes in multiple offerings, with terms allowing the company to use the proceeds to purchase bitcoin.

• Interest Rates: The bonds typically carry high-yield interest rates, averaging around 6-8% APR, depending on the specific issuance and market conditions at the time of issuance.

• Maturity: The bonds have varying maturities, with most structured for multi-year terms, offering investors medium-term exposure to bitcoin’s value trajectory through MicroStrategy’s holdings.

Pros

• Indirect Bitcoin exposure with income provides a unique opportunity for investors seeking income from bitcoin-backed debt.

• Bonds issued by MicroStrategy offer relatively high interest rates, appealing for fixed-income investors attracted to the higher risk/reward scenarios.

Cons

• There are credit risks tied to MicroStrategy’s financial health and bitcoin’s performance. A significant drop in bitcoin prices could strain the company’s ability to service debt, increasing credit risk.

• Availability: These bonds are primarily accessible to institutional investors and accredited investors, limiting availability for retail investors.

Interest Payable in Bitcoin – River has introduced an innovative product, bitcoin Interest on Cash, allowing clients to earn interest on their U.S. dollar deposits, with the interest paid in bitcoin.

Dynamics

• Interest Payment: Clients earn an annual interest rate of 3.8% on their cash deposits. The accrued interest is converted to Bitcoin daily and paid out monthly, enabling clients to accumulate Bitcoin over time.

• Security and Accessibility: Cash deposits are insured up to $250,000 through River’s banking partner, Lead Bank, a member of the FDIC. All Bitcoin holdings are maintained in full reserve custody, ensuring that client assets are not lent or leveraged.

Pros

• There are no hidden fees or minimum balance requirements, and clients can withdraw their cash at any time.

• The 3.8% interest rate provides a predictable income stream, akin to traditional fixed-income investments.

Cons

• While the interest rate is fixed, the value of the Bitcoin received as interest can fluctuate, introducing potential variability in the investment’s overall return.

• Interest rate payments are on the lower side

Admittedly, this is a very small list, however, these types of investments are growing more numerous and meaningful. The reality is the existing options aren’t numerous enough to service every client that has a need for fixed income exposure. I challenge advisors to explore innovative options for fixed income exposure outside of sovereign debt, as that is most certainly a road to nowhere. It is my wholehearted belief and call to action that we need more options to help clients across the risk and capital allocation spectrum access a sound money standard.

\ \ It was another historic week for both bitcoin and the Ten31 portfolio, as the world’s oldest, largest, most battle-tested cryptocurrency climbed to new all-time highs each day to close out the week just shy of the $100,000 mark. Along the way, bitcoin continued to accumulate institutional and regulatory wins, including the much-anticipated approval and launch of spot bitcoin ETF options and the appointment of several additional pro-bitcoin Presidential cabinet officials. The timing for this momentum was poetic, as this week marked the second anniversary of the pico-bottom of the 2022 bear market, a level that bitcoin has now hurdled to the tune of more than 6x despite the litany of bitcoin obituaries published at the time. The entirety of 2024 and especially the past month have further cemented our view that bitcoin is rapidly gaining a sense of legitimacy among institutions, fiduciaries, and governments, and we remain optimistic that this trend is set to accelerate even more into 2025.

Several Ten31 portfolio companies made exciting announcements this week that should serve to further entrench bitcoin’s institutional adoption. AnchorWatch, a first of its kind bitcoin insurance provider offering 1:1 coverage with its innovative use of bitcoin’s native properties, announced it has been designated a Lloyd’s of London Coverholder, giving the company unique, blue-chip status as it begins to write bitcoin insurance policies of up to $100 million per policy starting next month. Meanwhile, Battery Finance Founder and CEO Andrew Hohns appeared on CNBC to delve into the launch of Battery’s pioneering private credit strategy which fuses bitcoin and conventional tangible assets in a dual-collateralized structure that offers a compelling risk/return profile to both lenders and borrowers. Both companies are clearing a path for substantially greater bitcoin adoption in massive, untapped pools of capital, and Ten31 is proud to have served as lead investor for AnchorWatch’s Seed round and as exclusive capital partner for Battery.

As the world’s largest investor focused entirely on bitcoin, Ten31 has deployed nearly $150 million across two funds into more than 30 of the most promising and innovative companies in the ecosystem like AnchorWatch and Battery, and we expect 2025 to be the best year yet for both bitcoin and our portfolio. Ten31 will hold a first close for its third fund at the end of this year, and investors in that close will benefit from attractive incentives and a strong initial portfolio. Visit ten31.vc/funds to learn more and get in touch to discuss participating.\ \ Portfolio Company Spotlight 

Primal is a first of its kind application for the Nostr protocol that combines a client, caching service, analytics tools, and more to address several unmet needs in the nascent Nostr ecosystem. Through the combination of its sleek client application and its caching service (built on a completely open source stack), Primal seeks to offer an end-user experience as smooth and easy as that of legacy social media platforms like Twitter and eventually many other applications, unlocking the vast potential of Nostr for the next billion people. Primal also offers an integrated wallet (powered by Strike BLACK) that substantially reduces onboarding and UX frictions for both Nostr and the lightning network while highlighting bitcoin’s unique power as internet-native, open-source money. 

Selected Portfolio News

AnchorWatch announced it has achieved Llody’s Coverholder status, allowing the company to provide unique 1:1 bitcoin insurance offerings starting in December.\ \ Battery Finance Founder and CEO Andrew Hohns appeared on CNBC to delve into the company’s unique bitcoin-backed private credit strategy.

Primal launched version 2.0, a landmark update that adds a feed marketplace, robust advanced search capabilities, premium-tier offerings, and many more new features.

Debifi launched its new iOS app for Apple users seeking non-custodial bitcoin-collateralized loans.

Media

Strike Founder and CEO Jack Mallers joined Bloomberg TV to discuss the strong volumes the company has seen over the past year and the potential for a US bitcoin strategic reserve. 

Primal Founder and CEO Miljan Braticevic joined The Bitcoin Podcast to discuss the rollout of Primal 2.0 and the future of Nostr. 

Ten31 Managing Partner Marty Bent appeared on BlazeTV to discuss recent changes in the regulatory environment for bitcoin. 

Zaprite published a customer testimonial video highlighting the popularity of its offerings across the bitcoin ecosystem. 

Market Updates

Continuing its recent momentum, bitcoin reached another new all-time high this week, clocking in just below $100,000 on Friday. Bitcoin has now reached a market cap of nearly $2 trillion, putting it within 3% of the market caps of Amazon and Google. 

After receiving SEC and CFTC approval over the past month, long-awaited options on spot bitcoin ETFs were fully approved and launched this week. These options should help further expand bitcoin’s institutional liquidity profile, with potentially significant implications for price action over time.

The new derivatives showed strong performance out of the gate, with volumes on options for BlackRock’s IBIT reaching nearly $2 billion on just the first day of trading despite surprisingly tight position limits for the vehicles. 

Meanwhile, the underlying spot bitcoin ETF complex had yet another banner week, pulling in $3.4 billion in net inflows. 

New reports suggested President-elect Donald Trump’s social media company is in advanced talks to acquire crypto trading platform Bakkt, potentially the latest indication of the incoming administration’s stance toward the broader “crypto” ecosystem. 

On the macro front, US housing starts declined M/M again in October on persistently high mortgage rates and weather impacts. The metric remains well below pre-COVID levels. 

Pockets of the US commercial real estate market remain challenged, as the CEO of large Florida developer Related indicated that developers need further rate cuts “badly” to maintain project viability. 

US Manufacturing PMI increased slightly M/M, but has now been in contraction territory (<50) for well over two years.

The latest iteration of the University of Michigan’s popular consumer sentiment survey ticked up following this month’s election results, though so did five-year inflation expectations, which now sit comfortably north of 3%. 

Regulatory Update

After weeks of speculation, the incoming Trump administration appointed hedge fund manager Scott Bessent to head up the US Treasury. Like many of Trump’s cabinet selections so far, Bessent has been a public advocate for bitcoin. 

Trump also appointed Cantor Fitzgerald CEO Howard Lutnick – another outspoken bitcoin bull – as Secretary of the Commerce Department. 

Meanwhile, the Trump team is reportedly considering creating a new “crypto czar” role to sit within the administration. While it’s unclear at this point what that role would entail, one report indicated that the administration’s broader “crypto council” is expected to move forward with plans for a strategic bitcoin reserve.

Various government lawyers suggested this week that the Trump administration is likely to be less aggressive in seeking adversarial enforcement actions against bitcoin and “crypto” in general, as regulatory bodies appear poised to shift resources and focus elsewhere. 

Other updates from the regulatory apparatus were also directionally positive for bitcoin, most notably FDIC Chairman Martin Gruenberg’s confirmation that he plans to resign from his post at the end of President Biden’s term. 

Many critics have alleged Gruenberg was an architect of “Operation Chokepoint 2.0,” which has created banking headwinds for bitcoin companies over the past several years, so a change of leadership at the department is likely yet another positive for the space.

SEC Chairman Gary Gensler also officially announced he plans to resign at the start of the new administration. Gensler has been the target of much ire from the broader “crypto” space, though we expect many projects outside bitcoin may continue to struggle with questions around the Howey Test.

Overseas, a Chinese court ruled that it is not illegal for individuals to hold cryptocurrency, even though the country is still ostensibly enforcing a ban on crypto transactions. 

Noteworthy

The incoming CEO of Charles Schwab – which administers over $9 trillion in client assets – suggested the platform is preparing to “get into” spot bitcoin offerings and that he “feels silly” for having waited this long. As this attitude becomes more common among traditional finance players, we continue to believe that the number of acquirers coming to market for bitcoin infrastructure capabilities will far outstrip the number of available high quality assets. 

BlackRock’s 2025 Thematic Outlook notes a “renewed sense of optimism” on bitcoin among the asset manager’s client base due to macro tailwinds and the improving regulatory environment. Elsewhere, BlackRock’s head of digital assets indicated the firm does not view bitcoin as a “risk-on” asset. 

MicroStrategy, which was a sub-$1 billion market cap company less than five years ago, briefly breached a $100 billion equity value this week as it continues to aggressively acquire bitcoin. The company now holds nearly 350,000 bitcoin on its balance sheet. 

Notably, Allianz SE, Germany’s largest insurer, spoke for 25% of MicroStrategy’s latest $3 billion convertible note offering this week, suggesting growing appetite for bitcoin proxy exposure among more restricted pools of capital. 

The ongoing meltdown of fintech middleware provider Synapse has left tens of thousands of customers with nearly 100% deposit haircuts as hundreds of millions in funds remain missing, the latest unfortunate case study in the fragility of much of the US’s legacy banking stack.

Brazilian’s Central Bank Will Ban Monero and Algorithmic Stablecoins in the Country

Brazil proposes crypto regulations banning Monero and algorithmic stablecoins and enforcing strict compliance for exchanges.

---

KEY TAKEAWAYS

• The Central Bank of Brazil has proposed regulations prohibiting privacy-centric cryptocurrencies like Monero.
• The regulations categorize exchanges into intermediaries, custodians, and brokers, each with specific capital requirements and compliance standards.
• While the proposed rules apply to cryptocurrencies, certain digital assets like non-fungible tokens (NFTs) are still ‘deregulated’ in Brazil.

In a Notice of Participation announcement, the Brazilian Central Bank (BCB) outlines regulations for virtual asset service providers (VASPs) operating in the country.

In the document, the Brazilian regulator specifies that privacy-focused coins, such as Monero, must be excluded from all digital asset companies that intend to operate in Brazil.

Let’s unpack what effect these regulations will have.

Brazil’s Crackdown on Crypto Fraud

If the BCB’s current rule is approved, exchanges dealing with coins that provide anonymity must delist these currencies or prevent Brazilians from accessing and operating these assets.

The Central Bank argues that currencies like Monero make it difficult and even prevent the identification of users, thus creating problems in complying with international AML obligations and policies to prevent the financing of terrorism.

According to the Central Bank of Brazil, the bans aim to prevent criminals from using digital assets to launder money. In Brazil, organized criminal syndicates such as the Primeiro Comando da Capital (PCC) and Comando Vermelho have been increasingly using digital assets for money laundering and foreign remittances.

… restriction on the supply of virtual assets that contain characteristics of fragility, insecurity or risks that favor fraud or crime, such as virtual assets designed to favor money laundering and terrorist financing practices by facilitating anonymity or difficulty identification of the holder.

– Notice of Participation

The Central Bank has identified that removing algorithmic stablecoins is essential to guarantee the safety of users’ funds and avoid events such as when Terraform Labs’ entire ecosystem collapsed, losing billions of investors’ dollars.

The Central Bank also wants to control all digital assets traded by companies in Brazil. According to the current proposal, the national regulator will have the power to ask platforms to remove certain listed assets if it considers that they do not meet local regulations.

However, the regulations will not include NFTs, real-world asset (RWA) tokens, RWA tokens classified as securities, and tokenized movable or real estate assets. These assets are still ‘deregulated’ in Brazil.

Monero: What Is It and Why Is Brazil Banning It?

Monero ($XMR) is a cryptocurrency that uses a protocol called CryptoNote. It launched in 2013 and ‘erases’ transaction data, preventing the sender and recipient addresses from being publicly known. The Monero network is based on a proof-of-work (PoW) consensus mechanism, which incentivizes miners to add blocks to the blockchain. 

Like Brazil, other nations are banning Monero in search of regulatory compliance. Recently, Dubai’s new digital asset rules prohibited the issuance of activities related to anonymity-enhancing cryptocurrencies such as $XMR.

Furthermore, exchanges such as Binance have already announced they will delist Monero on their global platforms due to its anonymity features. Kraken did the same, removing Monero for their European-based users to comply with MiCA regulations.

Data from Chainalysis shows that Brazil is the seventh-largest Bitcoin market in the world.

In Latin America, Brazil is the largest market for digital assets. Globally, it leads in the innovation of RWA tokens, with several companies already trading this type of asset.

In Closing

Following other nations, Brazil’s regulatory proposals aim to combat illicit activities such as money laundering and terrorism financing.

While investing is essential for financial planning, it can be a dangerous and random game without a good strategy behind it. Because it not only can boost confidence that individuals can create a roadmap for financial success and minimize and mitigate risks to maximize return on investment. Long-term growth through investing strategically is key if you want to retire, accumulate wealth or become financially independent.

Why Investment Strategies are Important

Investment strategies act as roadmaps for financial development, guiding investors to:

• **Realize Financial Aims: ** Properly defined strategy positions investments with regard to short-term and long-term goals.
• Manage Risks: Appropriate diversification and asset allocation have the potential to alleviate market fluctuation.
• Maximize Returns: Investment with strategy provides superior decision-making and greater financial results.
• Stick to Plan: With strategy established, investors will be better at resisting spontaneous moves based on market volatility.
• Guarantee Financial Security: An organized investment strategy offers security and equips one with unforeseen financial conditions.

Key Steps towards Building an Investment Strategy

Having an efficient investment strategy in place calls for thoughtful planning and careful consideration of many aspects. Here are some key steps to create a winning strategy:

**1. Define Financial Goals ** Understanding financial objectives is the first step in developing a strategy for investments. The specification of goals can range from saving for a home to retirement or wealth generation. Hence, investing in them ensures alignment with the investor's personal priorities. Goals should always be specific, measurable, and time-bound such that progress can be tracked effectively.

**2. Assess the Risk Tolerance ** Every investor has a unique risk tolerance based on the financial situation and objectives. It is assessing risk tolerance that assists in deciding whether a portfolio is to be conservative, moderate, or aggressive in investments. Income stability, investment time horizon, and emotional tolerance for market volatility should all be taken into account.

**3. Diversify Investments ** Diversification eliminates risks by spreading investment across various asset classes, including stocks, bonds, real estate, and mutual funds. A diversified portfolio protects against such adverse movements so that decline in one market sector does not have a biting effect on band returns. It also provides a fair chance for capital gain while also maintaining stability.

**4. Invest Assets Judiciously ** Asset allocation is the strategy for spreading investments among different asset classes to provide a balance between risk and reward. A suitable mix can be derived with the help of a financial advisor based on the investment goals and risk tolerance. Hence, younger investors with a longer time horizon might be inclined to invest in more stocks while investors close to retirement could involve themselves in investments comprising a mix of bonds and fixed-income securities.

**5. Select the Appropriate Investment Tools ** Selection of investment tools forms various investment options that may examine diverse decisions in portfolio expansion. There are options:

• Stocks: Best for capital formation with the longest horizon, subject to market risks.
• Bonds: Provide regular income with lower risks. Generally chosen for capital preservation.
• Mutual Funds, ETFs: Diversified investment plan; managed by professionals-a mix of risk and return.
• Real Estate Investment: Passive income, diversification of portfolio, acts as an inflation hedge.
• Alternative Investments: Certifies commodities, hedge funds, currencies, all provide portfolio diversification while steering clear of any potential risks.

**6. Monitoring and Rebalancing Your Portfolio ** Over time, market conditions and personal finance situations will change. All investments should be checked from time to time to see if they are still in agreement with intended financial goals. Some adjustments may be required to improve performance and mitigate risk. Periodic rebalancing of a portfolio ensures that the asset allocation remains coherent with the initial investment regiment.

**7. Understand Tax Efficiency ** Tax planning for investment returns is crucial to optimize profit. Investors should engage, among other strategies, in tax-loss harvesting, investments in tax-advantaged accounts, or an understanding of the taxation of capital gains to minimize tax liabilities and, correspondingly, enhance returns.

While I can't provide a real photo, I can generate an image for you. Please imagine a breathtaking scene: The Pacific Ocean stretches out to the horizon, its vast expanse reflecting the sky's azure blue. Cliffs tower along the coastline, with Highway 1 winding its way atop, offering a spectacular view. The lush foliage of the Santa Cruz Mountains rolls gently inland, the shades of green contrasting beautifully with the deep blue of the ocean. Foamy white waves crash against the rocky shore, and the scent of the salty sea air seems almost tangible. The sun hangs low, casting a warm golden glow over the landscape. Let me know if there's anything specific you'd like to adjust in this mental image!On a crisp autumn afternoon, Alex fired up his vintage motorcycle, feeling the familiar rumble beneath him as he set off on what promised to be an unforgettable ride along California's famous Highway 1. The journey from Santa Cruz toward Big Sur was a favorite of his, a way to escape the hustle and bustle of daily life and embrace the vastness of the open road.

As he rode, the Pacific Ocean spread out to his right, a shimmering expanse of sapphire blue beneath the clear sky. To the left, the foothills of the Santa Cruz Mountains rose and fell, their slopes blanketed with lush, green foliage that danced in the gentle breeze. The air was filled with the crisp, salty tang of the sea, mingling with the earthy scents of the forest, creating a symphony of fragrances that heightened his senses.

The road curved and twisted along the cliff edges, each turn revealing a new and breathtaking panorama. Nearing a particularly picturesque section of the highway, Alex decided to pull over. The sun was beginning its descent, casting a warm, golden glow that painted the landscape in hues of amber and ochre, ideal for capturing the moment's beauty.

He parked his motorcycle on a gravelly outcrop and dismounted, fumbling in his jacket pocket for his phone. He balanced carefully on the edge of the cliff, the ocean's waves crashing rhythmically against the rocks far below. As he framed the perfect shot, the thrill of the moment flooded his senses. The cliffs, the ocean, the descending sun—all of it was a testament to the wild beauty of the world.

With a satisfied smile, he captured the image. But as he turned to head back to his bike, his foot slipped on the loose gravel. It all happened in a blur—one moment he was steady, the next he was tumbling, the world spinning around him. Desperately, Alex reached out, his hand instinctively breaking his fall, only to cry out in pain as a sharp jolt ran up his arm.

When he finally stopped rolling, he was thankfully still on the roadside, just a few feet from where he'd stood. With his heart pounding in his chest and pain radiating from his wrist, he realized he'd been incredibly lucky. Bruised and scraped, he struggled to sit up, cradling his injured wrist.

A passing car soon stopped, and a concerned driver offered assistance, helping Alex back to his feet and ensuring he got the medical help he needed. At the hospital, the doctor confirmed what Alex already suspected—a broken wrist. It would be weeks before he could ride again, but he knew it could have been much worse.

As he sat in the hospital bed, his mind returned to the image he'd captured just moments before the fall—a perfect scene of nature’s grandeur and his own fleeting vulnerability. It was a reminder of the precarious balance between beauty and danger, a lesson he'd carry with him long after the cast came off his wrist.

Spam is the single biggest problem in decentralized networks. Jameson Lopp, co-founder of Casa and OG bitcoiner, has written a brilliant article on the death of decentralized email that paints a vivid picture of what went wrong—and how an originally decentralized protocol was completely captured. The cause? Spam.

The same fate may happen to Nostr, because posting a note is fundamentally cheap. Payments, and to some extent Proof of Work, certainly have their role in fighting spam, but they introduce friction, which doesn’t work everywhere. In particular, they can’t solve every economic problem.\ Take free trials, for example. There is a reason why 99% of companies offer them. Sure, you waste resources on users who don’t convert, but it’s a calculated cost, a marketing expense. Also, some services can’t or don’t want to monetize directly. They offer something for free and monetize elsewhere.

So how do you offer a free trial or giveaway in a hostile decentralized network? Or even, how do you decide which notes to accept on your relay?

At first glance, these may seem like unrelated questions—but they’re not. Generally speaking, these are situations where you have a finite budget, and you want to use it well. You want more of what you value — and less of what you don’t (spam).

Reputation is a powerful shortcut when direct evaluation isn’t practical. It’s hard to earn, easy to lose — and that’s exactly what makes it valuable.\ Can a reputable user do bad things? Absolutely. But it’s much less likely, and that’s the point. Heuristics are always imperfect, just like the world we live in.

The legacy Web relies heavily on email-based reputation. If you’ve ever tried to log in with a temporary email, you know what I’m talking about. It just doesn’t work anymore. The problem, as Lopp explains, is that these systems are highly centralized, opaque, and require constant manual intervention.\ They also suck. They put annoying roadblocks between the world and your product, often frustrating the very users you’re trying to convert.

At Vertex, we take a different approach.\ We transparently analyze Nostr’s open social graph to help companies fight spam while improving the UX for their users. But we don’t take away your agency—we just do the math. You take the decision of what algorithm and criteria to use.

Think of us as a signal provider, not an authority.\ You define what reputation means for your use case. Want to rank by global influence? Local or personalized? You’re in control. We give you actionable and transparent analytics so you can build sharper filters, better user experiences, and more resilient systems. That’s how we fight spam, without sacrificing decentralization.
