2025-05-17 12:59:01The Myth and the Magic
Picture this: a group of investors, huddled around a glowing computer screen, nervously watching Bitcoin’s price. Suddenly, someone produces a stick-no ordinary stick, but a magical one. With a mischievous grin, they poke the Bitcoin. The price leaps upward. Cheers erupt. The legend of the Bitcoin stick is born.
But why does poking Bitcoin with a stick make the price go up? Why does it only work for a lucky few? And what does the data say about this mysterious phenomenon? Let’s dig in, laugh a little, and maybe learn the secret to market-moving magic.
The Statistical Side of Stick-Poking
Bitcoin’s Price: The Wild Ride
Bitcoin’s price is famous for its unpredictability. In the past year, it’s soared, dipped, and soared again, sometimes gaining more than 50% in just a few months. On a good day, billions of dollars flow through Bitcoin trades, and the price can jump thousands in a matter of hours. Clearly, something is making this happen-and it’s not just spreadsheets and financial news.
What Actually Moves the Price?
-
Scarcity: Only 21 million Bitcoins will ever exist. When more people want in, the price jumps.
-
Big News: Announcements, rumors, and meme-worthy moments can send the price flying.
-
FOMO: When people see Bitcoin rising, they rush to buy, pushing it even higher.
-
Liquidations: When traders betting against Bitcoin get squeezed, it triggers a chain reaction of buying.
But let’s be honest: none of this is as fun as poking Bitcoin with a stick.
The Magical Stick: Not Your Average Twig
Why Not Every Stick Works
You can’t just grab any old branch and expect Bitcoin to dance. The magical stick is a rare artifact, forged in the fires of internet memes and blessed by the spirit of Satoshi. Only a chosen few possess it-and when they poke, the market listens.
Signs You Have the Magical Stick
-
When you poke, Bitcoin’s price immediately jumps a few percent.
-
Your stick glows with meme energy and possibly sparkles with digital dust.
-
You have a knack for timing your poke right after a big event, like a halving or a celebrity tweet.
-
Your stick is rumored to have been whittled from the original blockchain itself.
Why Most Sticks Fail
-
No Meme Power: If your stick isn’t funny, Bitcoin ignores you.
-
Bad Timing: Poking during a bear market just annoys the blockchain.
-
Not Enough Hype: If the bitcoin community isn’t watching, your poke is just a poke.
-
Lack of Magic: Some sticks are just sticks. Sad, but true.
The Data: When the Stick Strikes
Let’s look at some numbers:
-
In the last month, Bitcoin’s price jumped over 20% right after a flurry of memes and stick-poking jokes.
-
Over the past year, every major price surge was accompanied by a wave of internet hype, stick memes, or wild speculation.
-
In the past five years, Bitcoin’s biggest leaps always seemed to follow some kind of magical event-whether a halving, a viral tweet, or a mysterious poke.
Coincidence? Maybe. But the pattern is clear: the stick works-at least when it’s magical.
The Role of Memes, Magic, and Mayhem
Bitcoin’s price is like a cat: unpredictable, easily startled, and sometimes it just wants to be left alone. But when the right meme pops up, or the right stick pokes at just the right time, the price can leap in ways that defy logic.
The bitcoin community knows this. That’s why, when Bitcoin’s stuck in a rut, you’ll see a flood of stick memes, GIFs, and magical thinking. Sometimes, it actually works.
The Secret’s in the Stick (and the Laughs)
So, does poking Bitcoin with a stick really make the price go up? If your stick is magical-blessed by memes, timed perfectly, and watched by millions-absolutely. The statistics show that hype, humor, and a little bit of luck can move markets as much as any financial report.
Next time you see Bitcoin stalling, don’t just sit there. Grab your stick, channel your inner meme wizard, and give it a poke. Who knows? You might just be the next legend in the world of bitcoin magic.
And if your stick doesn’t work, don’t worry. Sometimes, the real magic is in the laughter along the way.

2025-05-17 08:26:13背景:WhatsApp的号码验证与运营商合作关系
作为一款基于手机号码注册的即时通信应用,WhatsApp的账号验证严重依赖全球电信运营商提供的短信或电话服务。这意味着,当用户注册或在新设备登录WhatsApp时,WhatsApp通常会向用户的手机号码发送SMS短信验证码或发起语音电话验证。这一流程利用了传统电信网络的基础设施,例如通过SS7(信令系统7)协议在全球范围内路由短信和电话securityaffairs.com。换句话说,WhatsApp把初始账户验证的安全性建立在电信运营商网络之上。然而,这种依赖关系也带来了隐患:攻击者可以利用电信网络的漏洞来拦截验证码。例如,研究人员早在2016年就演示过利用SS7协议漏洞拦截WhatsApp和Telegram的验证短信,从而劫持用户账户的攻击方法securityaffairs.com。由于SS7协议在全球范围内连接各国运营商,一个运营商的安全缺陷或恶意行为都可能被不法分子利用来获取他网用户的短信验证码securityaffairs.com。正因如此,有安全专家指出,仅依赖短信验证不足以保障账户安全,WhatsApp等服务提供商需要考虑引入额外机制来核实用户身份securityaffairs.com。
除了技术漏洞,基于电信运营商的验证还受到各地政策和网络环境影响。WhatsApp必须与全球各地运营商“合作”,才能将验证码送达到用户手机。然而这种“合作”在某些国家可能并不顺畅,典型例子就是中国。在中国大陆,国际短信和跨境电话常受到严格管控,WhatsApp在发送验证码时可能遭遇拦截或延迟sohu.com。因此,理解WhatsApp在中国的特殊联网和验证要求,需要将其全球验证机制与中国的电信政策和网络审查环境联系起来。下文将深入探讨为什么在中国使用WhatsApp进行号码验证时,必须开启蜂窝移动数据,并分析其中的技术逻辑和政策因素。
中国环境下的特殊问题:为何必须开启蜂窝数据?
中国的网络审查与封锁: WhatsApp自2017年起就在中国大陆遭遇严格封锁。起初,WhatsApp在华的服务受到**“GFW”(防火长城)**的部分干扰——例如曾一度只能发送文本消息,语音、视频和图片消息被封锁theguardian.com。到2017年下半年,封锁升级,很多用户报告在中国完全无法使用WhatsApp收发任何消息theguardian.com。中国官方将WhatsApp与Facebook、Telegram等西方通信平台一同屏蔽,视作对国家网络主权的挑战theguardian.com。鉴于此,在中国境内直接访问WhatsApp的服务器(无论通过Wi-Fi还是本地互联网)都会被防火长城所阻断。即使用户收到了短信验证码,WhatsApp客户端也无法在没有特殊连接手段的情况下与服务器完成验证通信。因此,单纯依赖Wi-Fi等本地网络环境往往无法完成WhatsApp的注册或登陆。很多用户经验表明,在中国使用WhatsApp时需要借助VPN等工具绕过审查,同时尽可能避免走被审查的网络路径sohu.com。
强制Wi-Fi热点与连接策略: 除了国家级的封锁,用户所连接的局域网络也可能影响WhatsApp验证。许多公共Wi-Fi(如机场、商场)采取强制门户认证(captive portal),用户需登录认证后才能上网。对此,WhatsApp在客户端内置了检测机制,当发现设备连入这类强制Wi-Fi热点而无法访问互联网时,会提示用户忽略该Wi-Fi并改用移动数据faq.whatsapp.com。WhatsApp要求对此授予读取Wi-Fi状态的权限,以便在检测到被拦截时自动切换网络faq.whatsapp.com。对于中国用户来说,即便所连Wi-Fi本身联网正常,由于GFW的存在WhatsApp依然可能视之为“不通畅”的网络环境。这也是WhatsApp官方指南中强调:如果Wi-Fi网络无法连接WhatsApp服务,应直接切换到手机的移动数据网络faq.whatsapp.com。在中国,由于本地宽带网络对WhatsApp的封锁,蜂窝数据反而成为相对可靠的通道——尤其在搭配VPN时,可以避开本地ISP的审查策略,实现与WhatsApp服务器的通信sohu.com。
国际短信的运营商限制: 使用移动数据还有助于解决短信验证码接收难题。中国的手机运营商出于防垃圾短信和安全考虑,默认对国际短信和境外来电进行一定限制。许多中国用户发现,注册WhatsApp时迟迟收不到验证码短信,原因可能在于运营商将来自国外服务号码的短信拦截或过滤sohu.com。例如,中国移动默认关闭国际短信接收,需要用户主动发送短信指令申请开通sohu.com。具体而言,中国移动用户需发送文本“11111”到10086(或10085)来开通国际短信收发权限;中国联通和电信用户也被建议联系运营商确认未屏蔽国际短信sohu.com。若未进行这些设置,WhatsApp发送的验证码短信可能根本无法抵达用户手机。在这种情况下,WhatsApp提供的备用方案是语音电话验证,即通过国际电话拨打用户号码并播报验证码。然而境外来电在中国也可能遭到运营商的安全拦截,特别是当号码被认为可疑时zhuanlan.zhihu.com。因此,中国用户经常被建议开启手机的蜂窝数据和漫游功能,以提高验证码接收的成功率sohu.com。一方面,开启数据漫游意味着用户准备接受来自境外的通信(通常也包含短信/电话);另一方面,在数据联网的状态下,WhatsApp可以尝试通过网络直接完成验证通信,从而减少对SMS的依赖。
移动数据的网络路径优势: 在实际案例中,一些中国WhatsApp用户报告仅在开启蜂窝数据的情况下才能完成验证。这可能归因于蜂窝网络和宽带网络在国际出口上的差异。中国移动、联通等运营商的移动数据可能走与宽带不同的网关路由,有时对跨境小流量的拦截相对宽松。此外,WhatsApp在移动数据环境中可以利用一些底层网络特性。例如,WhatsApp可能通过移动网络发起某些专用请求或利用运营商提供的号码归属地信息进行辅助验证(虽然具体实现未公开,但这是业界讨论的可能性)。总之,在中国特殊的网络环境下,开启蜂窝数据是确保WhatsApp验证流程顺利的重要一步。这一步不仅是为了基本的互联网连接,也是为了绕开种种对国际短信和应用数据的拦截限制,从而与WhatsApp的全球基础设施建立必要的通讯。
PDP Context与IMSI:移动网络验证的技术细节
要理解为什么移动数据对WhatsApp验证如此关键,有必要了解移动通信网络中的一些技术细节,包括PDP Context和IMSI的概念。
PDP Context(分组数据协议上下文): 当手机通过蜂窝网络使用数据(如4G/5G上网)时,必须先在运营商核心网中建立一个PDP上下文。这实际上就是申请开启一个数据会话,运营商将为设备分配一个IP地址,并允许其通过移动核心网访问互联网datascientest.com。PDP上下文包含了一系列参数(例如APN接入点名称、QoS等级等),描述该数据会话的属性datascientest.comdatascientest.com。简单来说,激活蜂窝数据就意味着创建了PDP上下文,设备获得了移动网络网关分配的IP地址,可以收发数据包。对于WhatsApp验证而言,只有在建立数据连接后,手机才能直接与WhatsApp的服务器交换数据,例如提交验证码、完成加密密钥协商等。如果仅有Wi-Fi而蜂窝数据关闭,且Wi-Fi环境无法连通WhatsApp服务器,那么验证过程将陷入停滞。因此,在中国场景下,开启蜂窝数据(即建立PDP数据通路)是WhatsApp客户端尝试绕过Wi-Fi限制、直接通过移动网络进行验证通信的前提faq.whatsapp.comsohu.com。值得一提的是,PDP Context的建立也表明手机在运营商网络上处于活跃状态,这对于某些验证机制(比如后述的闪信/闪呼)来说至关重要。
IMSI与MSISDN: IMSI(国际移动用户标识)和MSISDN(移动用户号码,即手机号码)是运营商网络中两个密切相关但不同的标识。IMSI是存储在SIM卡上的一串唯一数字,用于在移动网络中标识用户身份netmanias.com。当手机接入网络时,它向运营商提供IMSI以进行鉴权,运营商据此知道“是哪张SIM”的请求netmanias.com。而MSISDN则是我们平常说的手机号,用于在语音通话和短信路由中定位用户,也存储在运营商的HLR/HSS数据库中netmanias.com。运营商通过IMSI<->MSISDN的对应关系,将来自全球的短信/电话正确路由到用户手机上。WhatsApp的验证短信或电话本质上就是通过目标号码(MSISDN)寻找所属运营商网络,由该网络根据IMSI定位用户终端。一般情况下,WhatsApp应用并不直接接触IMSI这种信息,因为IMSI属于运营商网络的内部标识。然而,IMSI的存在仍然对安全产生影响。例如,**SIM卡交换(SIM Swap)**欺诈发生时,攻击者获得了受害者号码的新SIM卡,新SIM卡会有不同的IMSI,但MSISDN保持原号码不变。运营商会将原号码映射到新的IMSI,这样验证码短信就发送到了攻击者手中的SIM上。对WhatsApp而言,除非有机制检测IMSI变动,否则无法察觉用户号码背后的SIM已被盗换。部分应用在检测到SIM变化时会提示用户重新验证,这需要读取设备的IMSI信息进行比对。然而,在现代智能手机中,获取IMSI通常需要特殊权限,WhatsApp并未明确说明它有此类检测。因此,从WhatsApp角度,IMSI更多是网络侧的概念,但它提醒我们:电信级身份验证依赖于SIM的有效性。只有当正确的IMSI在网络注册、并建立了PDP数据上下文时,WhatsApp的后台服务才能确认该SIM对应的号码目前“在线”,进而可靠地发送验证信号(短信或电话)到该设备。
移动网络的信号辅助验证: 有观点认为,一些OTT应用可能利用移动网络提供的附加服务来辅助号码验证。例如,某些运营商提供号码快速验证API,当应用检测到设备在移动数据网络中时,可以向特定地址发起请求,由运营商返回当前设备的号码信息(通常通过已经建立的PDP通道)。Google等公司在部分国家与运营商合作过类似服务,实现用户免输入验证码自动完成验证。但就WhatsApp而言,没有公开证据表明其使用了运营商提供的自动号码识别API。即便如此,WhatsApp鼓励用户保持移动网络在线的做法,隐含的意义之一可能是:当手机处于蜂窝网络且数据畅通时,验证码通过率和验证成功率都会显著提升。这既包括了物理层面短信、电话能否送达,也涵盖了数据层面应用和服务器能否互通。
Flash Call机制:WhatsApp验证的新方案
针对传统SMS验证码容易被拦截、延迟以及用户体验不佳的问题,WhatsApp近年来引入了一种Flash Call(闪呼)验证机制fossbytes.com。所谓闪呼,即应用在用户验证阶段向用户的手机号发起一个非常短暂的来电:用户无需真正接听,WhatsApp会自动结束这通电话,并根据通话记录来确认是否拨通fossbytes.com。
原理与流程: 当用户选择使用闪呼验证(目前主要在Android设备上可用),WhatsApp会请求权限访问用户的通话记录fossbytes.com。随后应用拨打用户的号码,一般是一个预先设定的特定号码或号码段。由于WhatsApp后台知道它拨出的号码及通话ID,只要该未接来电出现在用户手机的通话日志中,应用即可读取并匹配最后一通来电的号码是否符合验证要求,从而确认用户持有这个号码fossbytes.com。整个过程用户无需手动输入验证码,验证通话在数秒内完成。相比6位数字短信验证码需要用户在短信和应用间切换输入,闪呼方式更加快捷无缝fossbytes.com。
优缺点分析: 闪呼验证的优势在于速度快且避免了SMS可能的延迟或拦截。一些分析指出闪呼将成为取代SMS OTP(一次性密码)的新趋势,Juniper Research预测2022年用于验证的闪呼次数将从2021年的六千万猛增到五十亿次subex.comglobaltelcoconsult.com。对于WhatsApp这样全球用户庞大的应用,闪呼可以节约大量SMS网关费用,并绕开部分运营商对国际SMS的限制。然而,闪呼也有局限:fossbytes.com首先,iOS设备由于系统安全限制,应用无法访问通话记录,因此iPhone上无法使用闪呼验证fossbytes.com。这意味着苹果用户仍需使用传统短信验证码。其次,为实现自动匹配来电号码,用户必须授予读取通话记录的权限,这在隐私上引发一些担忧fossbytes.comfossbytes.com。WhatsApp声称不会将通话记录用于验证以外的用途,号码匹配也在本地完成fossbytes.com,但考虑到母公司Meta的隐私争议,部分用户依然顾虑。第三,闪呼验证依赖语音通话路线,同样受制于电信网络质量。如果用户所处网络无法接通国际来电(比如被运营商拦截境外短振铃电话),闪呼也无法成功。此外,从运营商角度看,闪呼绕过了A2P短信计费,可能侵蚀短信营收,一些运营商开始研究识别闪呼流量的策略wholesale.orange.com。总体而言,闪呼机制体现了WhatsApp希望减轻对短信依赖的努力,它在许多国家提升了验证体验,但在中国等特殊环境,其效果仍取决于本地语音网络的开放程度。值得注意的是,中国运营商对于境外电话,尤其是这种**“零响铃”未接来电**也有防范措施,中国电信和联通用户就被建议如需接收海外来电验证,应联系客服确保未拦截海外来电hqsmartcloud.com。因此,即便WhatsApp支持闪呼,中国用户若未开启移动语音漫游或运营商许可,仍然难以通过此途径完成验证。
与SIM Swap安全性的关系: 从安全角度看,闪呼并未实质提升抵御SIM交换攻击的能力。如果攻击者成功将受害者的号码转移至自己的SIM卡上(获取新IMSI),那么无论验证码以短信还是闪呼方式发送,都会到达攻击者设备。闪呼机制能防御的是部分恶意拦截短信的行为(如恶意网关或木马读取短信),但对社工换卡没有太大帮助。WhatsApp早已提供两步验证(即设置6位PIN码)供用户自行启用,以防号码被他人重新注册时需要额外密码。然而大量用户未开启该功能。因此,闪呼更多是从用户体验和成本出发的改良,而非针对高级别攻击的防护机制。正如前文所述,真正要防御SIM Swap和SS7漏洞等系统性风险,依赖运营商的号码验证本身就是薄弱环节,需要引入更高级的身份认证手段。
SIM卡交换攻击的风险与运营商信任问题
WhatsApp和Telegram一类基于手机号认证的应用普遍面临一个安全挑战:手机号码本身并非绝对安全的身份凭证。攻击者可以通过一系列手段取得用户的号码控制权,其中SIM交换(SIM Swap)是近年高发的欺诈手法。SIM Swap通常由不法分子冒充用户,诱骗或贿赂运营商客服将目标号码的服务转移到攻击者的新SIM卡上keepnetlabs.com。一旦成功,所有发往该号码的短信和电话都转由攻击者接收,原机主的SIM卡失效。对于依赖短信/电话验证的应用来说,这意味着攻击者可以轻易获取验证码,从而重置账户并登录。近年来全球SIM Swap案件呈上升趋势,许多在线服务的账号被此攻破rte.ie。
WhatsApp并非未知晓此风险。事实上,WhatsApp在其帮助中心和安全博客中多次提醒用户开启两步验证PIN,并强调绝不向他人透露短信验证码。然而,从系统设计上讲,WhatsApp仍将信任根基放在运营商发送到用户手机的那串数字验证码上。一旦运营商端的安全被绕过(无论是内部员工作恶、社工欺诈,还是SS7网络被黑客利用securityaffairs.com),WhatsApp本身无法辨别验证码接收者是否是真正的用户。正如安全研究所Positive Technologies指出的那样,目前主要的即时通讯服务(包括WhatsApp和Telegram)依赖SMS作为主要验证机制,这使得黑客能够通过攻击电信信令网络来接管用户账户securityaffairs.com。换言之,WhatsApp被迫信任每一个参与短信/电话路由的运营商,但这个信任链条上任何薄弱环节都可能遭到利用securityaffairs.com。例如,在SIM Swap攻击中,运营商本身成为被欺骗的对象;而在SS7定位拦截攻击中,全球互联的电信网成为攻击面。在中国的场景下,虽然主要威胁来自审查而非黑客,但本质上仍是WhatsApp无法完全掌控电信网络这一事实所导致的问题。
应对这些风险,WhatsApp和Telegram等采用了一些弥补措施。除了提供用户自行设定的二次密码,两者也开始探索设备多因子的概念(如后文Telegram部分所述,利用已有登录设备确认新登录)。然而,对绝大多数首次注册或更换设备的用户来说,传统的短信/电话验证仍是唯一途径。这就是为什么在高安全需求的行业中,SMS OTP正逐渐被视为不充分securityaffairs.com。监管机构和安全专家建议对涉敏感操作采用更强验证,如专用身份应用、硬件令牌或生物识别等。WhatsApp作为大众通信工具,目前平衡了易用性与安全性,但其依赖电信运营商的验证模式在像中国这样特殊的环境下,既遇到政策阻碍,也隐藏安全短板。这一点对于决策制定者评估国外通信应用在华风险时,是一个重要考量:任何全球运营商合作机制,在中国境内都可能因为**“最后一公里”由中国运营商执行**而受到影响。无论是被拦截信息还是可能的监控窃听,这些风险都源自于底层通信网的控制权不在应用服务商手中。
Telegram登录机制的比较
作为对比,Telegram的账号登录机制与WhatsApp类似,也以手机号码为主要身份标识,但在具体实现上有一些不同之处。
多设备登录与云端代码: Telegram从设计上支持多设备同时在线(手机、平板、PC等),并将聊天内容储存在云端。这带来的一个直接好处是:当用户在新设备上登录时,Telegram会优先通过已登录的其他设备发送登录验证码。例如,用户尝试在电脑上登录Telegram,Telegram会在用户手机上的Telegram应用里推送一条消息包含登录码,而不是立即发短信accountboy.comaccountboy.com。用户只需在新设备输入从老设备上收到的代码即可完成登录。这种机制确保了只要用户至少有一个设备在线,就几乎不需要依赖运营商短信。当然,如果用户当前只有一部新设备(例如换了手机且旧设备不上线),Telegram才会退而求其次,通过SMS发送验证码到手机号。同时,Telegram也允许用户选择语音电话获取验证码,类似于WhatsApp的语音验证。当用户完全无法收到SMS时(比如在中国这种场景),语音呼叫常常比短信更可靠seatuo.com。
两步验证密码: 与WhatsApp一样,Telegram提供可选的两步验证密码。当启用此功能后,即使拿到短信验证码,仍需输入用户设置的密码才能登录账户quora.com。这对抗SIM Swap等攻击提供了另一层防线。不过需要指出,如果用户忘记了设置的Telegram密码且没有设置信任邮箱,可能会永久失去账号访问,因此开启该功能在中国用户中接受度一般。
登录体验与安全性的取舍: Telegram的登录流程在用户体验上更加灵活。多设备下无需每次都收验证码,提高了便利性。但从安全角度看,这种“信任已有设备”的做法也有隐患:如果用户的某个设备落入他人之手并未及时登出,那么该人有可能利用该设备获取新的登录验证码。因此Telegram会在应用中提供管理活动会话的功能,用户可随时查看和撤销其它设备的登录状态telegram.org。总体而言,Telegram和WhatsApp在初始注册环节同样依赖短信/电话,在这一点上,中国的网络环境对两者影响相似:Telegram在中国同样被全面封锁,需要VPN才能使用,其短信验证码发送也会受到运营商限制。另外,Telegram曾在2015年因恐怖分子利用该平台传递信息而被中国当局重点关注并屏蔽,因此其国内可达性甚至比WhatsApp更低。许多中国用户实际使用Telegram时,通常绑定国外号码或通过海外SIM卡来收取验证码,以绕开国内运营商的限制。
差异总结: 简而言之,Telegram在登录验证机制上的主要优势在于已有会话协助和云端同步。这使得老用户换设备时不依赖国内短信通道即可登录(前提是原设备已登录并可访问)。WhatsApp直到最近才推出多设备功能,但其多设备模式采用的是端到端加密设备链路,需要主手机扫码授权,而非像Telegram那样用账号密码登录其它设备。因此WhatsApp仍然强绑定SIM卡设备,首次注册和更换手机号时逃不开运营商环节。安全方面,两者的SMS验证所面临的系统性风险(如SS7攻击、SIM Swap)并无本质区别,都必须仰仗运营商加强对核心网络的保护,以及用户自身启用附加验证措施securityaffairs.comkeepnetlabs.com。
结论
对于希望在中国使用WhatsApp的用户来说,“开启蜂窝数据”这一要求背后体现的是技术与政策交织的复杂现实。一方面,蜂窝数据承载着WhatsApp与其全球服务器通信的关键信道,在中国的受限网络中提供了相对可靠的出路faq.whatsapp.comsohu.com。另一方面,WhatsApp的号码验证机制深深植根于传统电信体系,必须经由全球运营商的“协作”才能完成用户身份确认securityaffairs.com。而在中国,这种协作受到防火长城和运营商政策的双重阻碍:国际短信被拦截、国际数据被阻断。为克服这些障碍,WhatsApp既采取了工程上的应对(如检测强制Wi-Fi并提示使用移动网络faq.whatsapp.com),也引入了诸如闪呼验证等新方案以减少对短信的依赖fossbytes.com。但从根本上说,只要注册流程离不开手机号码,这种与电信运营商的捆绑关系就无法割舍。由此带来的安全问题(如SIM Swap和信令网络漏洞)在全球范围内敲响警钟securityaffairs.comkeepnetlabs.com。
对于从事安全研究和政策评估的人士,这篇分析揭示了WhatsApp在中国遇到的典型困境:技术系统的全球化与监管环境的本地化冲突。WhatsApp全球统一的验证框架在中国水土不服,不得不通过额外的设置和手段来“曲线救国”。这既包括让用户切换网络、配置VPN等绕过审查,也包括思考未来是否有必要采用更安全独立的验证方式。相比之下,Telegram的机制给出了一种启示:灵活运用多设备和云服务,至少在一定程度上降低对单一短信渠道的依赖。然而,Telegram自身在中国的处境表明,再优雅的技术方案也难以直接对抗高强度的网络封锁。最终,无论是WhatsApp还是Telegram,要想在受限环境下可靠运作,都需要技术与政策的双管齐下:一方面提高验证与登录的安全性和多样性,另一方面寻求运营商和监管层面的理解与配合。
综上所述,WhatsApp要求中国用户开启蜂窝数据并非偶然的臆想,而是其全球运营商合作验证机制在中国受阻后的务实选择。这一要求折射出移动通信应用在跨境运营中面临的挑战,也提醒我们在设计安全策略时必须考虑底层依赖的信任假设。对于个人用户,最实际的建议是在使用此类应用时提前了解并遵循这些特殊设置(如开通国际短信、启用数据漫游),并善用应用自身的安全功能(如两步验证)来保护账户免遭社工和网络攻击keepnetlabs.com。对于监管和运营商,则有必要权衡安全审查与用户便利之间的平衡,在可控范围内为可信的全球服务留出技术通道。在全球通信愈加融合的时代,WhatsApp的中国验证问题或许只是一个缩影,背后涉及的既有网络安全考量,也有数字主权与国际合作的议题,值得持续深入研究和关注。

2025-05-17 13:03:39Man stelle sich vor, es droht Frieden auszubrechen. Wie stehen wir, die Deutschen, die Europäer denn dann da? Ja, wie die letzten Deppen, die ihr auch seid!
Wen wundert es, wenn nach erfolgreicher Friedensverhinderung durch Boris Johnson in 2022 und den durch den Westen zahlreichen überschrittenen Roten Linien Russland skeptisch ist?
Am russischen Misstrauen haben die hinter der Ukraine stehenden westlichen Staaten jahrelang erfolgreich gearbeitet.
„Besonderer Dank“ gilt hier vor allem der von allen Mitgliedern bedenkenlos hingenommenen NATO-Osterweiterung.
Die Aussage von Frau Merkel, man habe nie vorgehabt, das Minsk-Abkommen umzusetzen, stattdessen habe man gewollt, der Ukraine Zeit zu verschaffen, sich aufzurüsten, kann nur von jemandem, der weniger als eine Gehirnzelle hat, als vertrauensbildende Maßnahme bewertet werden.
Die immer wieder im Raum stehende Debatte um eine deutsche Lieferung von Kampf-Stieren, demnächst wohlmöglich unter Ausschluss der Öffentlichkeit (das könnte Teile der Bevölkerung verunsichern), ein weiteres Beispiel von friedenstüchtiger Diplomatie.
Wie schon beim klaglosen Hinnehmen der terroristischen Sprengung der Nordstream2 Pipelines, wozu Präsident Trump schon geäußert hat, dass es die Russen sicher nicht waren, wird auch brav von Deutschland hingenommen, dass von Wiesbaden aus, die Koordination der Raketenangriffe von der Ukraine auf Russland durch die USA, innerhalb der Task Force Dragon, gesteuert werden.
Die Verletzung des 2+4-Vertrages durch die Stationierung von Nicht-NATO-Truppen in Rostock, die an die Umbenennung eines Schokoriegels von Raider in Twixx erinnert.
Das strikte Einhalten der deutschen Maxime: „Von Deutschland soll nur noch Frieden ausgehen.“
Dazu die Lieferung von Raketen mit mittlerer Reichweite durch die Franzosen und Briten nach dem Motto: Ich habe nur das Messer auf den Tisch gelegt, zugestochen hat ein anderer.
All das trägt dazu bei, dass Russland vertrauensvoll nach europäischen Friedensvorschlägen geradezu lechzt. Unterstrichen werden diese übermenschlichen Anstrengungen durch ein weiteres, das bereit 17. Sanktionspaket. Dümmer geht’s nimmer.
Auch diplomatisch nicht zu überbietende Aussagen, wie „Russland wird immer unser Feind sein“, oder „Russland wird Deutschland in spätestens 5 Jahren angreifen“, oder „Deutschland muss wieder kriegstüchtig werden“, unterstreichen den unbedingten Willen, das sinnlose Sterben auf beiden Seiten schnellst möglich beenden zu wollen.
Außerhalb Deutschlands kann man nur zu der Überzeugung gelangen, dass es sich bei diesem Land um eine Freiluft-Irrenanstalt handeln muss. Und wer will schon mit geistig verwirrten Insassen über so ernste Themen wie Krieg und Frieden verhandeln, bei denen Verstand gebraucht wird.
Derartige Weltfremde ist nur mit Sarkasmus zu ertragen.
Bewundernswert der Langmut, den Russland bis heute an den Tag legt. Wäre die Situation umgekehrt, hätte der Westen schon lange dem „bösen“ Russen gezeigt, wo der US-Hammer hängt, und dass man so mit der sogenannten Wertegemeinschaft nicht umgehen kann.
Ja, der russische Einmarsch in die Ukraine war völkerrechtswidrig, genau so wie die US-amerikanischen „Besuche“ der USA in Vietnam, in Libyen und im Irak, auf sehr unschöne Weise. Wer hat nicht noch die Bilder vom Blitzgewitter der Bomben auf Bagdad im Gedächtnis. „Immer schön drauf, Stärke zeigen!“
Die zentrale Frage ist, wie man Deutschland „möglichst schonend“ beibringen kann, ohne, dass es einen größeren psychischen Staatsschaden davonträgt, dass es als Geisterfahrer auf der Friedensautobahn unterwegs ist.
Von russischer Seite sind nicht gerade die Vorstände der Kaninchenzüchter-Vereine nach Istanbul entsandt worden. Im Gegenteil, es handelt sich wohl eher um Personen, die bestens über das Kriegsgeschehen vor Ort Bescheid wissen.
Es darf nicht vergessen werden, dass es sich um einen Stellvertreterkrieg zwischen den von der Vorgängerregierung angezettelten USA und Russland, auf dem Rücken der Ukraine handelt.
In Istanbul haben sich zunächst die beiden Länder getroffen, deren Soldaten tatsächlich aufeinander schießen. Nicht die Strategen im Hintergrund. Und selbstverständlich beobachten die USA sehr wachsam, was vor sich geht und wie der Verlauf ist.
Es wäre fern der Realität, wenn im Hintergrund nicht weitere Fäden gesponnen würden, die der Öffentlichkeit zunächst vorenthalten werden. In diesem Fall kann das sogar von Vorteil sein, weil zu viele System-Journalisten den Brei mit dämlichen Kommentaren verderben könnten.
Zunächst soll zwischen den aktiv kämpfenden Parteien der Dialog wieder aufgenommen und eine Grundlage geschaffen werden, was schon ein großer Fortschritt ist, weil man sich seit 2022 überhaupt wieder erst einmal an einen gemeinsamen Tisch gesetzt hat und endlich wieder miteinander redet.
Wie immer im Krieg, wird auch hier strategisch vorgegangen und peinlichst darauf geachtet, dass alle Beteiligten möglichst weitgehend ihr Gesicht bewahren. Wer geglaubt hat, dass hier gleich Friedenstauben aufsteigen und alles mit einem Bruderkuss besiegelt wird, der ist wirklich ziemlich naiv.
Erst, wenn Sondierungsgespräche und Vorverhandlungen so weit gediehen sind, dass „nur“ noch eine Unterschrift fehlt, treten Putin und Trump als Friedensbringer auf die Bühne und besiegeln den „Deal“. Wie man jetzt an dem Vorführen Selenskyjs durch Putin gesehen hat, dient dieser nur noch als Spielball, der beim Ping-Pong um den Frieden hin- und hergeworfen wird. Trump hatte zuvor Selensky bei seinem Besuch im Weißen Haus ganz deutlich gesagt, dass er die Karten nicht in der Hand hat.
Jeder, der bei Verstand geblieben ist, wünscht sich endlich ein Ende dieses sinnlosen Sterbens, doch der Druck muss im Kessel langsam und kontrolliert abgelassen werden.
Entgegen der im Westen weitverbreiteten Propaganda-Lüge, der Konflikt in der Ukraine habe im Februar 2022 angefangen, hat sich die Situation über Jahre, mindestens mit der NATO-Osterweiterung aufgebaut. Da kann niemand erwarten, dass die Wiederherstellung eines Gleichgewichts jetzt in kürzester Zeit erreicht werden kann.
Urheber dieser Tragödie ist die NATO, die Russland immer mehr auf die Pelle gerückt ist. Hätte sie sich seinerzeit, wie der Warschauer Pakt, aufgrund der veränderten Kräfteverhältnisse ebenfalls aufgelöst, würden heute rund 1 Million Männer auf beiden Seiten sehr wahrscheinlich noch leben. Es wäre zu wünschen, dass nach dem exemplarischen Desaster in der Ukraine neue Überlegungen angestrengt werden würden, ob nicht die NATO, als Relikt aus alten Zeiten und aus Missachtung ihres Gründungsgedanken, ein Verteidigungsbündnis sein zu wollen, von der Zeit eingeholt wurde und ihrer Auflösung entgegensehen muss.

2025-05-16 20:52:42Streams are the key to nostr
Loading events from a nostr relay is probably the most inconsistent way of loading data I've had to work with, and that's only loading from a single relay. the problem gets exponentially more complicated once you try to load events from multiple relays
Unlike HTTP nostr does not have a simple flow with timeouts built in. events are sent back one at a time and can fail at any point or have massive (10s) gaps between them
The key is to use streams. something that starts, emits any number of results, then maybe errors or completes. luckily it just so happens that JavaScript / TypeScript has a great observable stream library called RxJS
What is an observable
An
Observable
in RxJS is stream a of data that are initialized lazily, which means the stream is inactive and not running until something subscribes to it```ts let stream = new Observable((observer) => { observer.next(1) observer.next(2) observer.next(3) observer.complete() })
// The stream method isn't run until its subscribed to stream.subscribe(v => console.log(v)) ```
This is super powerful and perfect for nostr because it means we don't need to manage the life-cycle of the stream. it will run when something subscribes to it and stop when unsubscribed.
Its helpful to think of this as "pulling" data. once we have created an observable we can request the data from it at any point in the future.
Pulling data from relays
We can use the lazy nature of observables to only start fetching events from a nostr relay when we need them
For example we can create an observable that will load kind 1 events from the damus relay and stream them back as they are returned from the relay
```typescript let req = new Observable((observer) => { // Create a new websocket connection when the observable is start let ws = new WebSocket('wss://relay.damus.io')
ws.onopen = () => { // Start a REQ ws.send(JSON.stringify(['REQ', 'test', {kinds: [1], limit: 20}])) }
ws.onmessage = (event) => { let message = JSON.parse(event.data) // Get the event from the message and pass it along to the subscribers if(message[0] === 'EVENT') observer.next(message[1]) }
// Cleanup subscription return () => { ws.send(JSON.stringify(['CLOSE', 'test'])) ws.close() } }) ```
But creating the observable wont do anything. we need to subscribe to it to get any events.
ts let sub = req.subscribe(event => { console.log('we got an event' event) })
Cool now we are pulling events from a relay. once we are done we can stop listening to it by unsubscribing from it
ts sub.unsubscribe()
This will call the cleanup method on the observable, which in turn closes the connection to the relay.
Hopefully you can see how this work, we don't have any
open
,connect
, ordisconnect
methods. we simply subscribe to a stream of events and it handles all the messy logic of connecting to a relayComposing and chaining observables
I've shown you how we can create a simple stream of events from a relay, but what if we want to pull from two relays?
Easy, lets make the previous example into a function that takes a relay URL
```ts function getNoteFromRelay(relay: string){ return new Observable((observer) => { let ws = new WebSocket(relay)
// ...rest of the observable...
}) } ```
Then we can "merge" two of these observables into a single observable using the
merge
method from RxJSThe
merge
method will create a single observable that subscribes to both upstream observables and sends all the events back. Think of it as pulling events from both relays at once```ts import { merge } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') )
// Subscribe to the observable to start getting data from it const sub = notes.subscribe(event => { console.log(event) })
// later unsubscribe setTimeout(() => { sub.unsubscribe() }, 10_000) ```
But now we have a problem, because we are pulling events from two relays we are getting duplicate events. to solve this we can use the
.pipe
method and thedistinct
operator from RxJS to modify our single observable to only return one version of each eventThe
.pipe
method will create a chain of observables that will each subscribe to the previous one and modify the returned values in some wayThe
distinct
operator takes a method that returns a unique identifier and filters out any duplicate values```ts import { merge, distinct } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') ).pipe( // filter out events we have seen before based on the event id distinct(event => event.id) ) ```
Now we have an observable that when subscribed to will connect to two relays and return a stream of events without duplicates...
As you can see things can start getting complicated fast. but its also very powerful because we aren't managing any life-cycle code, we just subscribe and unsubscribe from an observable
Taking it to an extreme
Hopefully at this point you can see how powerful this is, we can think of almost any data loading pattern as a series of observables that pull data from upstream observables and stream it back to the original subscriber.
Here is a quick sketch of what it could look like to load user profiles. each node is an observable that "pulls" data from its child node ending with the "connect websocket" or "load from database" nodes which do the work of making a relay connection
Conclusion
All this might seem pretty simple and straight forward, but its been a long six month of learning for me. I've had to completely rethink how data and nostr events should be handled in a client and how to avoid screwing up and shooting myself in the foot with these powerful tools.
If you want to give RxJS a try I would encourage you to checkout the nostr sdk I've been building called applesauce
Its uses RxJS for pretty much everything and has the simplest and most flexible relay connection API I've seen so far (mainly no life-cycle management)

Listen to the full episode here:
<<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

2025-05-16 18:06:46Bitcoin 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.
Using stolen bitcoin for the reserve creates a perverse incentive. If governments see 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.

2025-05-16 20:57:43Google says that Android 16 is slated to feature an optional high security mode. Cool.
Advanced Protection has a bunch of requested features that address the kinds of threats we worry about.
It's the kind of 'turn this one thing on if you face elevated risk' that we've been asking for from Google.
And likely reflects some learning after Google watched Apple 's Lockdown Mode play out. I see a lot of value in this..
Here are some features I'm excited to see play out:
The Intrusion Logging feature is interesting & is going to impose substantial cost on attackers trying to hide evidence of exploitation. Logs get e2ee encrypted into the cloud. This one is spicy.
The Offline Lock, Inactivity Reboot & USB protection will frustrate non-consensual attempts to physically grab device data.
Memory Tagging Extension is going to make a lot of attack & exploitation categories harder.
2G Network Protection & disabling Auto-connect to insecure networks are going to address categories of threat from things like IMSI catchers & hostile WiFi.
I'm curious about some other features such as:
Spam & Scam detection: Google messages feature that suggests message content awareness and some kind of scanning.
Scam detection for Phone by Google is interesting & coming later. The way it is described suggests phone conversation awareness. This also addresses a different category of threat than the stuff above. I can see it addressing a whole category of bad things that regular users (& high risk ones too!) face. Will be curious how privacy is addressed or if this done purely locally. Getting messy: Friction points? I see Google thinking these through, but I'm going to add a potential concern: what will users do when they encounter friction? Will they turn this off & forget to re-enable? We've seen users turn off iOS Lockdown Mode when they run into friction for specific websites or, say, legacy WiFi. They then forget to turn it back on. And stay vulnerable.
Bottom line: users disabling Apple's Lockdown Mode for a temporary thing & leaving it off because they forget to turn it on happens a lot. This is a serious % of users in my experience...
And should be factored into design decisions for similar modes. I feel like a good balance is a 'snooze button' or equivalent so that users can disable all/some features for a brief few minute period to do something they need to do, and then auto re-enable.
Winding up:
I'm excited to see how Android Advanced Protection plays with high risk users' experiences. I'm also super curious whether the spam/scam detection features may also be helpful to more vulnerable users (think: aging seniors)...
Niche but important:
Some users, esp. those that migrated to security & privacy-focused Android distros because of because of the absence of such a feature are clear candidates for it... But they may also voice privacy concerns around some of the screening features. Clear communication from the Google Security / Android team will be key here.

2025-05-16 17:59:23Recently we have seen a wave of high profile X accounts hacked. These attacks have exposed the fragility of the status quo security model used by modern social media platforms like X. Many users have asked if nostr fixes this, so lets dive in. How do these types of attacks translate into the world of nostr apps? For clarity, I will use X’s security model as representative of most big tech social platforms and compare it to nostr.
The Status Quo
On X, you never have full control of your account. Ultimately to use it requires permission from the company. They can suspend your account or limit your distribution. Theoretically they can even post from your account at will. An X account is tied to an email and password. Users can also opt into two factor authentication, which adds an extra layer of protection, a login code generated by an app. In theory, this setup works well, but it places a heavy burden on users. You need to create a strong, unique password and safeguard it. You also need to ensure your email account and phone number remain secure, as attackers can exploit these to reset your credentials and take over your account. Even if you do everything responsibly, there is another weak link in X infrastructure itself. The platform’s infrastructure allows accounts to be reset through its backend. This could happen maliciously by an employee or through an external attacker who compromises X’s backend. When an account is compromised, the legitimate user often gets locked out, unable to post or regain control without contacting X’s support team. That process can be slow, frustrating, and sometimes fruitless if support denies the request or cannot verify your identity. Often times support will require users to provide identification info in order to regain access, which represents a privacy risk. The centralized nature of X means you are ultimately at the mercy of the company’s systems and staff.
Nostr Requires Responsibility
Nostr flips this model radically. Users do not need permission from a company to access their account, they can generate as many accounts as they want, and cannot be easily censored. The key tradeoff here is that users have to take complete responsibility for their security. Instead of relying on a username, password, and corporate servers, nostr uses a private key as the sole credential for your account. Users generate this key and it is their responsibility to keep it safe. As long as you have your key, you can post. If someone else gets it, they can post too. It is that simple. This design has strong implications. Unlike X, there is no backend reset option. If your key is compromised or lost, there is no customer support to call. In a compromise scenario, both you and the attacker can post from the account simultaneously. Neither can lock the other out, since nostr relays simply accept whatever is signed with a valid key.
The benefit? No reliance on proprietary corporate infrastructure.. The negative? Security rests entirely on how well you protect your key.
Future Nostr Security Improvements
For many users, nostr’s standard security model, storing a private key on a phone with an encrypted cloud backup, will likely be sufficient. It is simple and reasonably secure. That said, nostr’s strength lies in its flexibility as an open protocol. Users will be able to choose between a range of security models, balancing convenience and protection based on need.
One promising option is a web of trust model for key rotation. Imagine pre-selecting a group of trusted friends. If your account is compromised, these people could collectively sign an event announcing the compromise to the network and designate a new key as your legitimate one. Apps could handle this process seamlessly in the background, notifying followers of the switch without much user interaction. This could become a popular choice for average users, but it is not without tradeoffs. It requires trust in your chosen web of trust, which might not suit power users or large organizations. It also has the issue that some apps may not recognize the key rotation properly and followers might get confused about which account is “real.”
For those needing higher security, there is the option of multisig using FROST (Flexible Round-Optimized Schnorr Threshold). In this setup, multiple keys must sign off on every action, including posting and updating a profile. A hacker with just one key could not do anything. This is likely overkill for most users due to complexity and inconvenience, but it could be a game changer for large organizations, companies, and governments. Imagine the White House nostr account requiring signatures from multiple people before a post goes live, that would be much more secure than the status quo big tech model.
Another option are hardware signers, similar to bitcoin hardware wallets. Private keys are kept on secure, offline devices, separate from the internet connected phone or computer you use to broadcast events. This drastically reduces the risk of remote hacks, as private keys never touches the internet. It can be used in combination with multisig setups for extra protection. This setup is much less convenient and probably overkill for most but could be ideal for governments, companies, or other high profile accounts.
Nostr’s security model is not perfect but is robust and versatile. Ultimately users are in control and security is their responsibility. Apps will give users multiple options to choose from and users will choose what best fits their need.

2025-05-16 17:51:54In much of the world, it is incredibly difficult to access U.S. dollars. Local currencies are often poorly managed and riddled with corruption. Billions of people demand a more reliable alternative. While the dollar has its own issues of corruption and mismanagement, it is widely regarded as superior to the fiat currencies it competes with globally. As a result, Tether has found massive success providing low cost, low friction access to dollars. Tether claims 400 million total users, is on track to add 200 million more this year, processes 8.1 million transactions daily, and facilitates $29 billion in daily transfers. Furthermore, their estimates suggest nearly 40% of users rely on it as a savings tool rather than just a transactional currency.
Tether’s rise has made the company a financial juggernaut. Last year alone, Tether raked in over $13 billion in profit, with a lean team of less than 100 employees. Their business model is elegantly simple: hold U.S. Treasuries and collect the interest. With over $113 billion in Treasuries, Tether has turned a straightforward concept into a profit machine.
Tether’s success has resulted in many competitors eager to claim a piece of the pie. This has triggered a massive venture capital grift cycle in USD tokens, with countless projects vying to dethrone Tether. Due to Tether’s entrenched network effect, these challengers face an uphill battle with little realistic chance of success. Most educated participants in the space likely recognize this reality but seem content to perpetuate the grift, hoping to cash out by dumping their equity positions on unsuspecting buyers before they realize the reality of the situation.
Historically, Tether’s greatest vulnerability has been U.S. government intervention. For over a decade, the company operated offshore with few allies in the U.S. establishment, making it a major target for regulatory action. That dynamic has shifted recently and Tether has seized the opportunity. By actively courting U.S. government support, Tether has fortified their position. This strategic move will likely cement their status as the dominant USD token for years to come.
While undeniably a great tool for the millions of users that rely on it, Tether is not without flaws. As a centralized, trusted third party, it holds the power to freeze or seize funds at its discretion. Corporate mismanagement or deliberate malpractice could also lead to massive losses at scale. In their goal of mitigating regulatory risk, Tether has deepened ties with law enforcement, mirroring some of the concerns of potential central bank digital currencies. In practice, Tether operates as a corporate CBDC alternative, collaborating with authorities to surveil and seize funds. The company proudly touts partnerships with leading surveillance firms and its own data reveals cooperation in over 1,000 law enforcement cases, with more than $2.5 billion in funds frozen.
The global demand for Tether is undeniable and the company’s profitability reflects its unrivaled success. Tether is owned and operated by bitcoiners and will likely continue to push forward strategic goals that help the movement as a whole. Recent efforts to mitigate the threat of U.S. government enforcement will likely solidify their network effect and stifle meaningful adoption of rival USD tokens or CBDCs. Yet, for all their achievements, Tether is simply a worse form of money than bitcoin. Tether requires trust in a centralized entity, while bitcoin can be saved or spent without permission. Furthermore, Tether is tied to the value of the US Dollar which is designed to lose purchasing power over time, while bitcoin, as a truly scarce asset, is designed to increase in purchasing power with adoption. As people awaken to the risks of Tether’s control, and the benefits bitcoin provides, bitcoin adoption will likely surpass it.

2025-05-16 18:40:18Die zwei mächtigsten Krieger sind Geduld und Zeit. \ Leo Tolstoi
Zum Wohle unserer Gesundheit, unserer Leistungsfähigkeit und letztlich unseres Glücks ist es wichtig, die eigene Energie bewusst zu pflegen. Das gilt umso mehr für an gesellschaftlichen Themen interessierte, selbstbewusste und kritisch denkende Menschen. Denn für deren Wahrnehmung und Wohlbefinden waren und sind die rasanten, krisen- und propagandagefüllten letzten Jahre in Absurdistan eine harte Probe.
Nur wer regelmäßig Kraft tankt und Wege findet, mit den Herausforderungen umzugehen, kann eine solche Tortur überstehen, emotionale Erschöpfung vermeiden und trotz allem zufrieden sein. Dazu müssen wir erkunden, was uns Energie gibt und was sie uns raubt. Durch Selbstreflexion und Achtsamkeit finden wir sicher Dinge, die uns erfreuen und inspirieren, und andere, die uns eher stressen und belasten.
Die eigene Energie ist eng mit unserer körperlichen und mentalen Gesundheit verbunden. Methoden zur Förderung der körperlichen Gesundheit sind gut bekannt: eine ausgewogene Ernährung, regelmäßige Bewegung sowie ausreichend Schlaf und Erholung. Bei der nicht minder wichtigen emotionalen Balance wird es schon etwas komplizierter. Stress abzubauen, die eigenen Grenzen zu kennen oder solche zum Schutz zu setzen sowie die Konzentration auf Positives und Sinnvolles wären Ansätze.
Der emotionale ist auch der Bereich, über den «Energie-Räuber» bevorzugt attackieren. Das sind zum Beispiel Dinge wie Überforderung, Perfektionismus oder mangelhafte Kommunikation. Social Media gehören ganz sicher auch dazu. Sie stehlen uns nicht nur Zeit, sondern sind höchst manipulativ und erhöhen laut einer aktuellen Studie das Risiko für psychische Probleme wie Angstzustände und Depressionen.
Geben wir negativen oder gar bösen Menschen keine Macht über uns. Das Dauerfeuer der letzten Jahre mit Krisen, Konflikten und Gefahren sollte man zwar kennen, darf sich aber davon nicht runterziehen lassen. Das Ziel derartiger konzertierter Aktionen ist vor allem, unsere innere Stabilität zu zerstören, denn dann sind wir leichter zu steuern. Aber Geduld: Selbst vermeintliche «Sonnenköniginnen» wie EU-Kommissionspräsidentin von der Leyen fallen, wenn die Zeit reif ist.
Es ist wichtig, dass wir unsere ganz eigenen Bedürfnisse und Werte erkennen. Unsere Energiequellen müssen wir identifizieren und aktiv nutzen. Dazu gehören soziale Kontakte genauso wie zum Beispiel Hobbys und Leidenschaften. Umgeben wir uns mit Sinnhaftigkeit und lassen wir uns nicht die Energie rauben!
Mein Wahlspruch ist schon lange: «Was die Menschen wirklich bewegt, ist die Kultur.» Jetzt im Frühjahr beginnt hier in Andalusien die Zeit der «Ferias», jener traditionellen Volksfeste, die vor Lebensfreude sprudeln. Konzentrieren wir uns auf die schönen Dinge und auf unsere eigenen Talente – soziale Verbundenheit wird helfen, unsere innere Kraft zu stärken und zu bewahren.

2025-05-16 17:12:05One 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.

2025-05-16 17:32:56The rental population in Spain has grown from about 5 million in 2005 to around 10 million in 2025. During that same period, Spain's total population has increased by 6 million people, from 43 to 49 million. In other words, the entire population growth over the past 20 years has essentially gone straight into the rental market.
This demographic growth is not due to natural increase, Spain has one of the lowest fertility rates in the world. Instead, population growth is driven by a positive migratory balance, which has been the main factor behind the rise in rental demand.
This increased demand for rentals has pushed up rental prices, which have significantly outpaced the growth in property sale prices. That didn’t happen during the Great Financial Crisis. The growth in both demand and prices is allowing rental profitability to remain at the high end of the curve—around 5% net.
This situation explains the rise in housing squatting, from 2,000 cases in 2010 to 16,000 in 2024. Since the immigrant population is the main driver of this surge in rental demand, it is more vulnerable to squatting, as they often have no alternative housing when they are unable to pay.
The unemployment rate is currently low, however, if it were to rise (as it did during the Great Financial Crisis and other periods in the past), squatting would likely increase significantly, representing the main risk to the current real estate market in Spain.

2025-05-16 19:57:46Let's start with some important foundational thinking - based on natural law. Money should be separate from the State - if not history shows that governments and human greed will always take over and manipulate the system in their favour and the expense of their populations. For extensive references, read The Sovereign Individual and The Creature from Jeckyll Island.

The Separation of State and Money is the most important thing you can listen to this week. Thanks to Allen Farrington - his paper is here for those who prefer to read. Wake up, folks!

The American Forefathers knew this when the wrote the American Constitution. Thomas Jefferson said: “If the American people ever allow private banks to control the issue of their currency first by inflation then by deflation the banks and corporations that will grow up around them will deprive the people of all property until their children wake up homeless on the continent their Fathers conquered... I believe that banking institutions are more dangerous to our liberties than standing armies... The issuing power should be taken from the banks and restored to the people to whom it properly belongs.” Mark Moss explains it well here. Charlie Robinsons take here.
The situation in Canada exemplifies the issues
Governments have have long used "international economic sanctions" against other nations to enforce their positions. Now in Canada, and soon in your country too, they are applying such sanctions their own citizens - disconnecting them from the financial system and removing their ability to use their own life savings as they wish. Canadians spoke with their money - in one week they raised more money in support of the truckers for peaceful protest than were raised in support of all Canadian political parties in the election of last year - only to have it confiscated and blocked by those politicians.

Could you have known about this?
"The Matrix is a system, Neo. That system is our enemy. But when you're inside, you look around, what do you see? Businessmen, teachers, lawyers, carpenters. The very minds of the people we are trying to save. But until we do, these people are still a part of that system and that makes them our enemy. You have to understand, most of these people are not ready to be unplugged. And many of them are so inert, so hopelessly dependent on the system that they will fight to protect it."
"Unfortunately, no one can be told what the Matrix is. You have to see it for yourself."
A closing thought...
Look closely at the cover of the Economist magazine *released in December 2018 *- The World in 2019 - see how many of those things have already come true.
In case this is too difficult for you - some things to note: Four horsemen of the apacalypse, Statue of Liberty wearing a facemask, Vetruvian Man with QR code (Vaccine passport), DNA mark on his arm, wearing virtual reality glasses... The animal bottom right is a Pangolin. Scales of Justice are well tipped/skewed, facial recognition, electric cars, Putin's pipelines, China and Brexit feature highly along with the lieing media (Pinnochio) and #metoo. I smell Predictive Programming.

2025-05-17 06:31:52ความสำเร็จ จำเป็นต้องมีวินัย
ความมีวินัย คือ "การทำด้วยความตั้งใจ ไม่หวั่นไหว/ไหลตามไปกับอารมณ์" ส่วน "ความไร้วินัย" มีนัยยะตรงกันข้าม กล่าวคือ
ความไร้วินัย คือ "การทำตามความหวั่นไหว/ไหลตามไปกับอารมณ์" เช่น ความง่วง หิว เบื่อ เซ็ง พอใจ ไม่พอใจ กลัว หลงไหล/ขาดสติ เป็นต้น จนเกิดข้ออ้างสารพัด เช่น * อ้างว่าเดี๋ยวก่อน เอาไว้ทีหลัง * อ้างว่าเหนื่อยหน่าย * อ้างว่าร้อนไป หนาวไป * อ้างว่ายังเช้าอยู่ * อ้างว่าสายไปแล้ว * ฯลฯ
การสร้างวินัยที่ยั่งยืน "ไม่ได้เกิดจากการฝืน แต่เกิดจากความฝัน" กฎแห่งความฝันระบุว่า เราต้องสร้างภาพสวรรค์ (เป้าหมาย) ให้ชัด จากนั้นให้ลดช่องว่างระหว่างการคิดและการกระทำให้เหลือน้อยที่สุด เพราะถ้าเราคิดมาก ส่วนใหญ่เราจะไม่ได้ทำ จิตใจเราจะอ่อนแอ ไม่เข้มแข็งมั่นคง
กฎแห่งความฝัน ควรฝันเพื่อผู้อื่น อย่าฝันเพื่อตัวเองคนเดียว เพราะขณะที่จิตมุ่งเป้าสู่ความสำเร็จนั้นมัน ถ้ามันมีมากเกินไป สติปัญญาจะอ่อนค่าลง ความรอบรู้จะน้อยลง ณ ขณะนั้นการกระทำทั้งปวงจะขาดความเห็นอกเห็นใจผู้อื่นหากทำเพื่อตัวเองฝ่ายเดียว แต่ถ้าพลังมุ่งเป้าที่ส่วนรวม ทุกการกระทำจะส่งคุณค่าเกิดเป็นความสุขความสำเร็จร่วมกัน

@ 0b118e40:4edc09cb
2025-05-15 15:40:21My week started off with a lovely message from a friend : “I often think about you. Especially during times when it requires me to be more resilient and have faith in myself. I always carry your note in the book you gave me, “what the dog saw” And it always gives me courage and I send a little prayer your way”.
This friend of mine was dealing with the undercurrent of discrimination in my alma mater when we first met, and I helped out. It's something anybody would have done, but surprisingly, nobody else showed up. We’ve stayed in touch over the years, and my friend went on to help a lot of other people along the way.
I don’t remember what I wrote in that note. It’s something I tend to do (write notes, give books, write notes in books). But the message boomeranged back to me at a time when I needed to hold the line. To keep the faith.
Most of us don’t talk about our struggles. And sometimes the smallest act, which could just be a kind word or a reminder of the person you are, can carry farther than we imagine.
On the act of giving
There’s a book called Give and Take by Adam Grant. I picked it up hoping to learn how to take, because it’s always been easier to give and harder to accept help. But what I learned was something else entirely.
Grant studied over 30,000 people across different companies and grouped them into three types: * Givers * Matchers * Takers
Based on his studies, givers often finish last... They struggle the most. They burn out. They get overlooked. They’re too trusting.
But oddly, they also rise to the very top.
Matchers are the scorekeepers, the “I’ll help you if you help me” kind. They make up most of the population. The fascinating thing about tit-for-tat is that if someone’s kind, they reciprocate. But if someone acts like a jerk, they return the energy, and over time, it becomes a pool of spoiled milk. Matchers are a lukewarm, forgettable kind of network.
Takers are the ones chasing attention, always aligning themselves with whoever looks powerful. They tend to float toward status and soak up what they can. But they often portray themselves as kind and giving.
One example Grant shared was Enron's Kenneth Lay, who was at the center of one of the biggest corporate scandals in U.S. history. He hung around wherever he’d get seen or validated. He funded both Bush and Clinton, hedging his bets on who might win by securing proximity. Sadly, when Enron crumbled, he died of a heart attack before his prison sentencing.
Most people steer clear from takers because they are just exhausting. And takers often collapse under the weight of their own games.
But takers aren’t the lowest performers. That spot belongs to a certain kind of giver—the self-neglecting kind. The ones with no boundaries, no clarity, and no self-awareness. They give in to avoid conflict, to feel worthy, or because they don’t know how to say no. And when life breaks them, they point fingers.
Then there’s the other kind of giver. The ones who build trust and build people up without asking for a receipt.
These givers: 1. Give without expectation, from a place of purpose 2. Build and uplift others without seeking credit 3. Set boundaries and walk away when giving turns into draining
This group of givers rarely talk much about what they do for others. But when you hear about it or see it, it stays with you. It makes you want to show up a little better.
Why open source environments feels like home
The more I thought about it, the more I saw how deeply open source reflects that kind of giving that ends up right at the top.
In open source, you don’t last if it’s just about ego. You can’t fake it. There are no titles, no awards. You either show up to build and help, or you don’t.
People who give without needing to be seen are the ones the community leans on. You can tell when someone’s pretending to care. It’s in their tone, their urgency and their sense of transaction. The genuine ones don’t need to brand themselves as generous. They just are.
Open source works because giving is the default setting. The work speaks volumes and generosity compounds. The system filters for people who show up with purpose and stay consistent.
It’s also why the ones who whine, posture, or manipulate rarely last. They might call themselves givers, but they’re not fooling anyone who’s actually doing the work.
Adam Grant found that for giver cultures to thrive, takers have to be removed. They need to be pruned. Because takers poison the well. They drain givers, shift the culture from contribution to calculation, and unravel the trust that holds open systems together.
When hope boomerangs
That note is something I don’t remember writing. But it found its way back to me, and it was a good reminder to take my own advice and keep the faith.
And maybe that’s the point.
You do a small thing. And years later, it circles back when it matters most. Not because you expected it. But because you mattered.
According to Grant, givers do best when they combine generosity with grit and strategy. They create networks built on goodwill, which eventually open doors others don’t even know exist.
So if you’re wondering where I’m going with this, do something genuinely kind for someone today. Even if it’s as simple as sending a kind note. Not for you to be seen or heard. And not for you to keep scores.
But, just because.

2025-05-17 09:57:04What follows is my best effort to recall the details of an arguably supernatural encounter I experienced almost sixty years ago. I've told this story many times before, and while my recollection may not be perfect in every detail, my account is real and substantively factual.
It was early one long ago morning, in that twilit between-time shortly before dawn. As I dangled precariously in a quasi-aware state, hovering on the knife edge between wakefulness and sleep, I was transported in a dream to another place and time. Was it the Mediterranean coast? Perhaps ancient Greece?
In my mind's eye, I found myself climbing a rather steep, rocky hillside overlooking a sparkling bright blue sea. Ahead of me, and slightly higher, was what appeared to be a young shepherd boy, leading me ever higher up the hill.
As we wove our way upward,
skirting rocky outcroppings and zig-zagging because of the steepness of the slope, I heard the boy chanting:
"Ata, Ata, Archontos, Ata, Ata, Echousi, Ata, Ata, Archousi"
He kept repeating the mantra, over and over:
"Ata, Ata, Archontos, Ata, Ata, Echousi, Ata, Ata, Archousi"
\~ \~ \~
"Ata, Ata, Archontos, Ata, Ata, Echousi, Ata, Ata, Archousi"
I listened for a few cycles, and then took up the chant myself. After several attempts, when at last I got it right, the shepherd boy turned, looking back at me and smiling broadly to signal that I had finally mastered the cadence and the words.
Then I awoke.
Because my dream had been so vivid and unusual, I immediately found a pencil and paper to write down the chant phonetically before I could forget it.
A few days passed.
Life was busy. Then I remembered my friend in grad school, studying biblical Greek. That weekend, I went and hung out with him while he worked his night job at the college heating plant. Between his rounds inspecting and managing the steam boilers keeping students from freezing to death in the Arctic Midwest winter, I told him about my strange dream.
Pulling out an exhaustive Greek lexicon, one by one, my knowledgeable friend looked up the words from my dream, interpreting each according to its verb conjugation, tense, and mood.
"Ata, Ata" had no discernible meaning; we soon concluded that it was probably just meaningless vocables, added to give the chant rhythm and substance. My friend moved on to the first recognizable word of the chant...
"Archontos" - "They are ruled."
OK, so far, so good. He checked the next word:
"Echousi" - "They shed blood."
Hmmmm... This chant is beginning to appear to be more than random sounds.
"Archousi" - "They rule."
At this point, I almost fell out of my chair in shock. Far from being a meaningless chant, this cycle—repeating again and again—is the seemingly never-ending story of the entirety of human history...
"They Are Ruled, They Shed Blood, They Rule."
\~ \~ \~
"They Are Ruled, They Shed Blood, They Rule."
This concise mantra perfectly captures the endlessly repeating cycle of oppression, revolt, and revolution that always leaves us with a fresh set of oppressors all too ready to replace the last.
Who will rescue us?
Who will redeem us from this endless tedious cycle into which we have been born?
A long lifetime of study and reflection has persuaded me that this deadly cycle can and ultimately will be broken. If we follow the teachings of Jesus; if we love one another and live together in voluntary, local societies, serving each other; I am persuaded that we can break free of this desperately destructive cycle of endlessly seeking to dominate one another. It's past time for us to enter into a mutually beneficial life in the Kingdom of our Creator-God Jesus, the most authentically benevolent King the universe has ever known.

Uncertainty is the only constant
It goes without saying that uncertainty is a given in business. It could be the weather, pestilence, or some other physical phenomenon that brings different conditions for your business (good or bad). Or it could be uncertainty in the behaviour of consumers, suppliers, workers, or any other person critical to your success. Most of the time, we just don’t know what will happen next.
One of the most important skills in managing a business, then, is making predictions in the face of uncertainty. We have several tools to do so. The first covers methods from the physical sciences, and involves calculating the frequency of events. We need to unpick a concept at the root of uncertainty, probability.

Types of probability
In Human Action, Ludwig von Mises introduces us to two classifications of probability: case and class probability.
Case probability
Case probability is when we know something about some of the factors which determine the outcome, but not others.
This is the kind of probability most often encountered in business. We often know small key parts about several factors that lead to a particular outcome, we might see that oil prices have risen significantly, coupled with a decrease in the exchange rate. These factors help to lead to the outcome of a rising price of fertiliser. But then, there are other factors that lead to this outcome, such as a myriad of decisions by businesspeople all along the supply chain. These, we know absolutely nothing about!
Class probability
Class probability is when we know everything about the particular kind (or class) of event, but we don’t know anything at all about the specific event.
We do encounter class probability in business. But it happens at very specific times (as opposed to just all the time, as with case probability).
Myrtle rust, picture courtesy of NZ Department of Conservation
For example (and sticking to agriculture) we know nothing about an outbreak of Myrtle rust on our farm. But we know, from agricultural science, that the likelihood of an outbreak in our area for a given year is about 13 percent.
So how can we make predictions of these events?
Making predictions
For the latter (class probabilities, like losses caused by Myrtle rust) we can always rely on methods from the physical sciences to calculate frequencies. Then, we know that the physical world has certain constants, so we can say that given a set of conditions (like rainfall) the likelihood of losses from Myrtle rust in future is about 12 percent.
Thinking about the former (case probabilities such as changing consumer preferences, or changes in prices). In these situations we are dealing with the realm of human decisions. So while we can count the number of these events, we cannot use these counts for prediction. The reason is that, in the realm of human decisions, there are no constants. We can’t say that given the world of 2023 prices rose five times, therefore in the world of 2027 prices will rise five times. Even if physical conditions are the same, human decisions will not be.
Luckily, economic science does give us an answer. In dealing with case probabilities we should use our method of understanding (which I wrote about here).
Using this in your business
You can incorporate this knowledge into your business by critically analysing each event for which you need to make a prediction. Is the event dealing with the physical world, for which there are constants? Or is it the realm of human decisions, for which there are no constants? It most likely is a mix of these.
Work backwards and jot down the more granular events which compose the event in question. Then try again to fit each of these into case or class probability.
When each event is broken down into only one category you know which methods of prediction to apply to each event.
For case probabilities, engage a specialist in the area. For class probabilities, engage your own expertise in understanding, and consider hiring an economist to augment your analysis.

2025-05-17 11:16:18Bitcoin has been playing an increasingly important role in protests and social movements around the world. Thanks to its decentralized nature, resistance to censorship, and independence from government control, Bitcoin has become a valuable tool for activists, organizations, and citizens fighting against oppressive regimes or restrictive financial systems.
- Bitcoin as an alternative to the traditional financial system
In recent years, governments and banking institutions have used financial restrictions as a form of political repression. Frozen bank accounts, blocked donations, and limitations on transactions are some of the strategies used to weaken social movements and protests. Bitcoin offers an alternative, allowing funds to be transferred and stored without interference from banks or governments.
One of Bitcoin’s main advantages in these contexts is its censorship resistance. While bank accounts can be shut down and centralized payment services can be pressured to block transactions, Bitcoin operates on a decentralized network where no one can prevent a user from sending or receiving funds.
- Examples of Bitcoin use in protests
01 - Hong Kong (2019–2020): During the pro-democracy protests, activists faced financial restrictions when trying to organize demonstrations and campaigns. Many turned to Bitcoin to avoid surveillance by the Chinese government and to secure funding for their actions.
02 - Canada (2022): The truckers' protest against government restrictions saw participants' bank accounts frozen. As an alternative, Bitcoin donations were used to bypass financial repression.
03 - Belarus (2020): After the contested presidential elections, protesters used Bitcoin to fund activities and support those who lost their jobs due to state repression.
04 - Nigeria (2020): During the #EndSARS protests against police brutality, international donations to the movement were blocked. Bitcoin became one of the main methods for financing the cause.
- Challenges of using Bitcoin in social movements
01 - Education and accessibility: Many people still don’t know how to use Bitcoin safely and efficiently. This lack of knowledge can hinder large-scale adoption.
02 - Digital security: Social movements often operate under heavy surveillance. Without proper security measures, funds can be compromised.
03 - Volatility: Bitcoin’s price can fluctuate significantly in a short time, which may affect the value of donations and funds raised.
In summary, Bitcoin has proven to be an essential tool in resisting financial censorship and government repression. By enabling social movements and activists to fund their causes without intermediaries, Bitcoin strengthens the fight for freedom and justice. However, effective adoption of the technology requires knowledge, security, and adaptation to its unique characteristics. As more people learn to use Bitcoin, its role in protests and social movements will continue to grow, reinforcing the importance of financial sovereignty in the struggle for rights and freedoms.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-05-15 15:31:45Capitalism 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.

2025-05-15 15:25:27“Put that camera down, you bitch,” someone yelled out of a car as it drove by with the door wide open.
I had a little time in Savannah yesterday to walk around and take some photos. I tend to wander through the rougher areas — not just in Savannah, but in any city I visit. I’m drawn to the spots most people avoid. Not the tourist zones, but the alleys, the quiet, broken-down neighborhoods where the grit is.
I’ve photographed Savannah a lot over the past few years, so it’s getting harder to find places I haven’t already been. But every now and then, I’ll stumble on a back street or alley I’ve never seen before, and in it, something I’m almost certain no one else has photographed.
There’s something about walking aimlessly with a camera that I find incredibly fulfilling. Honestly, if I could do just that for the rest of my life — wander around and photograph things that most people overlook — I’d be content.
There’s a quote I heard recently - can’t remember who said it — but it stuck with me. It was something like: “It’s better to be aimless than to be rigid with a plan.” Because when you’re too locked into a goal, you might miss the opportunities that pop up along the way. You need to stay flexible, fluid—open to what the world hands you.
That’s how I feel about photography. I’ll walk for hours—sometimes five to ten miles — just to see what shows up. It becomes a game. A game between me, the camera, the street, and whatever decides to show up that day.
Usually, it takes a few warm-up shots to get into it — just pictures of objects, whatever catches my eye. But once I find a rhythm, it’s like the world starts to reveal itself. The good stuff comes out of hiding.
That’s what real photography is to me. Not staging scenes or setting up portraits—that’s more like illustration, as Garry Winogrand would say. What I care about is life. Life unfolding right in front of you. Life happening.
Thank you for your attention. Please consider donating a few sats if you enjoy my work. It goes a long way. If not, please share. Thank you.

2025-05-17 10:26:42Millions of people around the world still lack access to basic banking services, whether due to lack of infrastructure, bureaucratic requirements, or economic instability in their countries. Bitcoin emerges as an innovative solution to this problem, allowing anyone with internet access to have control over their money without relying on banks or governments. By offering an open and accessible financial system, Bitcoin becomes a powerful tool for global financial inclusion.
- The problem of financial exclusion
In many developing countries, a large portion of the population does not have a bank account. This can happen for several reasons, such as:
01 - Lack of access to banks: Many communities, especially in rural areas, do not have nearby financial institutions.
02 - Bureaucratic requirements: Some banks require specific documentation or a credit history that many people cannot provide.
03 - High costs: Banking fees can be prohibitive for those with low incomes.
04 - Economic and political instability: In countries with high inflation or unstable governments, banks may not be a safe option for storing money.
These challenges leave millions of people on the margins of the financial system, unable to save, invest, or carry out transactions efficiently.
- Bitcoin as an alternative
Bitcoin addresses many of the issues of financial exclusion by offering an accessible and decentralized system. With Bitcoin, anyone with a mobile phone and internet access can store and transfer money without needing a bank. Key advantages include:
01 - Global accessibility: Bitcoin can be used anywhere in the world, regardless of the user's location.
02 - No intermediaries: Unlike banks that impose fees and rules, Bitcoin allows direct transactions between people.
03 - Low-cost international transfers: Sending money to another country can be expensive and slow with traditional methods, while Bitcoin offers a faster and more affordable alternative.
04 - Protection against inflation: In countries with unstable currencies, Bitcoin can be used as a store of value, protecting the population’s purchasing power.
- Use cases in financial inclusion
Bitcoin is already being used to promote financial inclusion in various parts of the world. Some examples include:
01 - Africa and Latin America: In countries like Nigeria, Venezuela, and Argentina, where inflation is high and access to U.S. dollars is limited, many people use Bitcoin to preserve their money and make international transactions.
02 - International remittances: Workers sending money to their families abroad avoid the high fees of traditional transfer companies by using Bitcoin.
03 - Digital microeconomy: Small merchants and freelancers without access to bank accounts can receive payments in Bitcoin directly and securely.
- Challenges to financial inclusion with Bitcoin
Despite its advantages, Bitcoin adoption as a tool for financial inclusion still faces some challenges, such as:
01 - Internet access: Many impoverished regions still lack adequate digital infrastructure.
02 - Financial education: Greater knowledge of the technology and best security practices is needed for broader adoption.
03 - Price volatility: Value fluctuations can make Bitcoin difficult to use for everyday expenses, especially in countries where people live on unstable incomes.
In summary, Bitcoin offers a viable solution for millions of people excluded from the traditional financial system. By providing global access, low-cost transactions, and protection from inflation, it becomes a powerful instrument for promoting financial inclusion. However, for its full potential to be realized, it is essential to invest in digital education and expand technological infrastructure, enabling more people to achieve financial autonomy through Bitcoin.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-05-15 12:53:31It’s not big government programs or powerful institutions that make a society strong. It’s something much simpler: everyday people trading and working together.
Think about the local hardware store owner. He helps his neighbors, gives people jobs, and provides useful tools. But when the government taxes him too much to fund its programs, it takes away money he could have used to hire someone or visit his family. That hurts both him and the people around him.
This happens all over. Small business owners, tradesmen, inventors and entrepreneurs are the ones who really build up a society. They create value by trading things people want, and both sides benefit. Free trade gives people more choices and helps them live better lives.
But from a young age, we’re told to obey authority without question. We’re taught that without rulers, there would be chaos. But what if that’s not true?
Look around the world: even when governments try to control trade, people still find ways to work together and exchange goods. It’s natural. People want to cooperate and help each other—especially when they’re free to do so.
Here’s the hard truth: if someone can take your money, control your property, and punish you without your agreement, isn’t that a kind of control—or even servitude?
True prosperity doesn’t come from the top down. It comes from people freely working together—farmers, builders, cooks, coders—offering their skills to others who need them.
When trade is free, people do well. When it’s blocked by too many rules or taxes, everyone loses—especially the ones who need help the most.
The answer isn’t more laws or more control. It’s more freedom. Next time someone says we need more government to fix things, ask yourself: wouldn’t free people solve those problems better on their own?
Real civilization isn’t about being ruled. It’s about choosing to work together, trade fairly, and respect each other’s rights. That’s not chaos—that’s freedom.

2025-05-16 07:51:08Payjoin allows the sender and receiver of an on-chain payment to collaborate and create a transaction that breaks on-chain heuristics, allowing a more private transaction with ambiguous payment amount and UTXO ownership. Additionally, it can also be used for UTXO consolidation (receiver saves future fees) and batching payments (receiver can make payment(s) of their own in the process of receiving one), also known as transaction cut-through. Other than improved privacy, the rest of the benefits are typically applicable to the receiver, not the sender.
BIP-78 was the original payjoin protocol that required the receiver to run a endpoint/server (always online) in order to mediate the payjoin process. Payjoin adoption has remained pretty low, something attributed to the server & perpetual online-ness requirement. This is the motivation for payjoin v2.
The purpose of the one-pager is to analyse the protocol, and highlight the UX issues or tradeoffs it entails, so that the payjoin user flows can be appropriately designed and the tradeoffs likewise communicated. A further document on UX solutions might be needed to identify solutions and opportunities
The following observations are generally limited to individual users transacting through their mobile devices:
While users naturally want better privacy and fee-savings, they also want to minimise friction and minimise (optimise) payment time. These are universal and more immediate needs since they deal with the user experience.
Added manual steps
TL;DR v2 payjoin eliminates server & simultaneous user-liveness requirements (increasing TAM, and opportunities to payjoin, as a result) by adding manual steps.
Usually, the extent of the receiver's involvement in the transaction process is limited to sharing their address with the sender. Once they share the address/URI, they can basically forget about it. In the target scenario for v2 payjoin, the receiver must come online again (except they have no way of knowing "when") to contribute input(s) and sign the PSBT. This can be unexpected, unintuitive and a bit of a hassle.
Usually (and even with payjoin v1), the sender crafts and broadcasts the transaction in one go; meaning the user's job is done within a few seconds/minutes. With payjoin v2, they must share the original-PSBT with the receiver, and then wait for them to do their part. Once the the receiver has done that, the sender must come online to review the transaction, sign it & broadcast.
In summary,
In payjoin v1, step 3 is automated and instant, so delay 2, 3 =~ 0. As the user experiences it, the process is completed in a single session, akin to a non-payjoin transaction.
With payjoin v2, Steps 2 & 3 in the above diagram are widely spread and noticeable. These manual steps are separated by uncertain delays (more on that below) when compared to a non-payjoin transaction.
Delays
We've established that both senders and receivers must take extra manual steps to execute a payoin transaction. With payjoin v2, this process gets split into multiple sessions, since the sender and receiver are not like to be online simultaneously.
Delay 2 & 3 (see diagram above) are uncertain in nature. Most users do not open their bitcoin wallets for days or weeks! The receiver must come online before the timeout hits in order for the payjoin process to work, otherwise time is just wasted with no benefit. UX or technical solutions are needed to minimise these delays.
Delays might be exacerbated if the setup is based on hardware wallet and/or uses multisig.
Notifications or background processes
There is one major problem when we say "the user must come online to..." but in reality the user has no way of knowing there is a payjoin PSBT waiting for them. After a PSBT is sent to the relay, the opposite user would only find out about it whenever they happen to come online. Notifications and background sync processes might be necessary to minimise delays. This is absolutely essential to avert timeouts in addition to saving valuable time. Another risk is phantom payjoin stuff after the timeout is expired if receiver-side does not know it has.
Fee Savings
The following observations might be generally applicable for both original and this v2 payjoin version. Fee-savings with payjoin is a tricky topic. Of course, overall a payjoin transaction is always cheaper than 2 separate transactions, since they get to share the overhead.
Additionally, without the receiver contributing to fees, the chosen fee rate of the PSBT (at the beginning) drops, and can lead to slower confirmation. From another perspective, a sender paying with payjoin pays higher fees for similar confirmation target. This has been observed in a production wallet years back. Given that total transaction time can extend to days, the fee environment itself might change, and all this must be considered when designing the UX.
Of course, there is nothing stopping the receiver from contributing to fees, but this idea is likely entirely novel to the bitcoin ecosystem (perhaps payments ecosystem in general) and the user base. Additionally, nominally it involves the user paying fees and tolerating delays just to receive bitcoin. Without explicit incentives/features that encourage receivers to participate, payjoining might seem like an unncessary hassle.
Overall, it seems that payjoin makes UX significant tradeoffs for important privacy (and potential fee-saving) benefits. This means that the UX might have to do significant heavy-lifting, to ensure that users are not surprised, confused or frustrated when they try to transact on-chain in a privacy-friendly feature. Good, timely communication, new features for consolidation & txn-cutthrough and guided user flows seem crucial to ensure payjoin adoption and for help make on-chain privacy a reality for users.

2025-05-16 05:38:28LegoGPT generates a LEGO structure from a user-provided text prompt in an end-to-end manner. Notably, our generated LEGO structure is physically stable and buildable.
Lego is something most of us knows. This is a opportuity to ask where is our creativity going? From the art of crafting figures to building blocks following our need and desires to have a machine thinking and building following step-by-step instructions to achieve an isolated goal.
Is the creative act then in the question itself, not anymore in the crafting? Are we just delegating the solution of problems, the thinking of how to respond to questions, to machines? Would it be different if delegated to other people?

2025-05-12 14:50:36A posição do libertário que rejeita o cristianismo padece de sérias incoerências lógicas, históricas e filosóficas. Ao renegar as bases espirituais e culturais que tornaram possível o próprio ideal libertário, tal posição demonstra ser, ao mesmo tempo, autofágica e irracional. É o caso de alguém que se gloria dos frutos de uma árvore que corta pela raiz.
I. Fundamento histórico: a civilização da liberdade é cristã
Não foi o secularismo moderno, nem o paganismo antigo, que ergueram as instituições que protegem a dignidade da pessoa humana e os limites ao poder. Desde os primeiros séculos, a Igreja resistiu ao culto estatal romano, afirmando a soberania de Deus sobre os Césares — "Mais importa obedecer a Deus que aos homens" (Atos 5,29).
Foi o cristianismo que:
-
Fundou universidades livres, onde o saber era buscado sob o primado da verdade;
-
Defendeu a lei natural como fundamento do direito — uma doutrina que protege o indivíduo contra tiranias;
-
Resgatou e aprofundou o conceito de pessoa, dotada de razão e livre-arbítrio, imagem de Deus, e, portanto, inalienavelmente digna e responsável.
Em momentos-chave da história, como nas disputas entre papado e império, nas resistências contra absolutismos, e na fundação do direito internacional por Francisco de Vitoria e a Escola de Salamanca, foi o cristianismo quem freou o poder estatal em nome de princípios superiores. A tradição cristã foi frequentemente o principal obstáculo à tirania, não seu aliado.
Negar isso é amputar a própria genealogia da liberdade ocidental.
Uma das chaves do cristianismo para a construção dessa civilização da liberdade foi a exaltação do individualismo. Ao afirmar que o ser humano é feito à imagem de Deus e que sua salvação é uma escolha pessoal, o cristianismo colocou o indivíduo no centro da moralidade e da liberdade. Diferente dos gregos, cuja ética era voltada para a polis e a cidade-estado, o cristianismo reafirma a suprema importância do indivíduo, com sua capacidade de escolha moral, responsabilidade pessoal e dignidade intrínseca. Esse princípio, mais do que qualquer outra religião, foi o alicerce do desenvolvimento da liberdade individual e da autonomia, valores que sustentam a civilização ocidental.
A ética grega, na melhor das hipóteses, descreve a ordem natural — mas não consegue justificar por que essa ordem deveria obrigar a vontade humana. Um Logos impessoal não tem autoridade moral. Uma ordem cósmica sem um Legislador é apenas um dado de fato, não uma norma vinculante. A vontade pode rebelar-se contra o telos — e sem um Deus justo, que ordena a natureza à perfeição, não há razão última para não o fazer.
A cultura grega teve uma influência indiscutível sobre o desenvolvimento da civilização ocidental, mas o cristianismo não só absorveu o que havia de bom na cultura grega, como também elevou e completou esses aspectos. O cristianismo, ao afirmar que todos os homens são feitos à imagem e semelhança de Deus e têm dignidade intrínseca, levou a uma noção de igualdade moral e liberdade que transcende as limitações da pólis grega.
II. Falsa dicotomia: fé e liberdade não são opostas
Com frequência equiparam a religião à coerção e à obediência cega. Mas isso é um equívoco: o cristianismo não se impõe pela força, mas apela à consciência. O próprio Deus, em sua relação com a criatura racional, respeita sua liberdade. Como ensina a Escritura:
"Se alguém quiser vir após mim..." (Mt 16,24);
"Eis que estou à porta e bato. Se alguém ouvir a minha voz e abrir a porta, entrarei em sua casa e cearei com ele." (Ap 3,20);
"Assim falai, e assim procedei, como devendo ser julgados pela lei da liberdade." (Tiago 2,12).A adesão à fé deve ser livre, voluntária e racional, pois sem liberdade não há verdadeiro mérito, nem amor genuíno. Isso é mais compatível com o princípio de não agressão do que qualquer utopia secular. Ora, o núcleo do evangelho é voluntarista: salvação pessoal, conversão interior, caridade.
Ninguém deve ser forçado, contra sua vontade, a abraçar a fé, pois o ato de fé é por sua natureza voluntário (Dignitatis Humanae; CDC, cân. 748,2)
Se algum Estado usa da força para impor o cristianismo, afirmar que o cristianismo causou as coerções é tão equivocado quanto dizer que a propriedade privada causa o comunismo; é uma inversão da realidade, pois o comunismo surge precisamente da violação da propriedade. Portanto, a fé forçada é inválida em si mesma, pois viola a natureza do ato de crer, que deve ser livre.
III. Fundamento moral: sem transcendência, o libertarianismo flutua no vácuo
O libertário anticristão busca defender princípios objetivos — como a inviolabilidade do indivíduo e a ilegitimidade da agressão — sem um fundamento transcendente que lhes dê validade universal. Por que a agressão é errada? Por que alguém tem direito à vida, à liberdade, à propriedade? Sem uma explicação transcendental, as respostas para tais perguntas se tornam apenas opiniões ou convenções, não obrigações morais vinculantes. Se a moralidade é puramente humana, então os direitos podem ser modificados ou ignorados conforme a vontade da sociedade. O conceito de direitos naturais, tão caro ao libertarianismo, precisa de um solo metafísico que justifique sua universalidade e imutabilidade. Caso contrário, eles podem ser tratados apenas como acordos utilitários temporários ou preferências culturais, sem qualquer obrigatoriedade para todos os seres humanos em todas as circunstâncias.
Pensadores libertários seculares, como Ayn Rand e Murray Rothbard, tentaram ancorar os direitos naturais na razão humana ou na natureza do homem. Rand baseia sua ética no egoísmo racional, enquanto Rothbard apela à lei natural. Embora essas abordagens busquem objetividade, elas carecem de uma resposta definitiva para por que a razão ou a natureza humana obrigam moralmente todos os indivíduos. Sem um fundamento transcendente, suas concepções permanecem vulneráveis a interpretações subjetivas ou a cálculos utilitários.
Aqui, o cristianismo oferece uma explicação sólida e transcendental que fundamenta os direitos naturais. A visão cristã de que o ser humano foi criado à imagem e semelhança de Deus confere à pessoa uma dignidade intrínseca, imutável e universal. Essa dignidade não depende de fatores externos, como consenso social ou poder político, mas é uma característica inerente ao ser humano pela sua criação divina. A partir dessa perspectiva teológica, torna-se possível afirmar com base sólida que os direitos naturais são dados por Deus e, portanto, são universais e vinculantes.
O cristianismo também é a base de um sistema moral que distingue claramente justiça de legalidade. O Estado pode criar leis, mas isso não significa que essas leis sejam justas. A justiça, sob a ótica cristã, é uma expressão da ordem moral objetiva, algo que transcende as leis humanas e é definido pela vontade divina. Por isso, o libertarianismo cristão vê a agressão como uma violação de uma ordem moral objetiva, e não apenas uma violação de uma convenção social ou de um acordo utilitário.
Se a moralidade e os direitos naturais não forem fundamentados em um Logos criador e legislador, o que acontece é que o conceito de direito natural degenera para algo mais frágil, como um simples acordo utilitário. Nesse cenário, os direitos do indivíduo se tornam algo acordado entre os membros de uma sociedade, em vez de princípios imutáveis e universais. Os direitos podem ser negociados, alterados ou ignorados conforme o interesse do momento.
IV. Fundamento científico: a racionalidade moderna é filha da fé cristã
A ciência moderna só foi possível no contexto cultural cristão. Nenhuma outra civilização — nem a grega, nem a islâmica, nem a chinesa — produziu o método científico como o Ocidente cristão o fez.
Isso se deve a quatro premissas teológicas:
-
Criação racional: O mundo é ordenado por um Deus racional.
-
Distinção entre Criador e criatura: A natureza não é divina e pode ser estudada sem sacrilégio.
-
Valor do trabalho e da observação empírica, herdado do monaquismo.
-
Autonomia institucional, presente nas universidades medievais.
A doutrina cristã da Criação ex nihilo ensina que o mundo foi criado por um Deus racional, sábio e pessoal. Portanto, o cosmos é ordenado, possui leis, e pode ser compreendido pela razão humana — que é imagem do Criador. Isso contrasta fortemente com as cosmovisões panteístas ou mitológicas, onde o mundo é cíclico, arbitrário ou habitado por forças caprichosas.
Sem essa fé no Logos criador, não há razão para crer que a natureza tenha uma ordem inteligível universal e constante, que pode ser descoberta por observação e dedução. A ciência moderna só é possível porque, antes de investigar a natureza, pressupôs-se que ela era investigável — e isso foi uma herança direta do pensamento cristão.
Homens como Bacon, Newton, Kepler e Galileu viam na ciência um modo de glorificar o Criador. O ateísmo cientificista é, portanto, parasitário da teologia cristã, pois toma seus frutos e rejeita suas raízes. A ciência moderna nasceu como filha legítima da fé cristã. E os que hoje a usam contra sua mãe, ou são ingratos, ou ignorantes.
V. O cristianismo como barreira à revolução cultural
O cristianismo é a barreira mais sólida contra a infiltração revolucionária. A chamada "marcha gramsciana", que visa corroer os fundamentos morais da sociedade para subjugar o indivíduo ao coletivo, encontra sua resistência mais firme nos princípios cristãos. A fé cristã, ao proclamar a existência de uma verdade objetiva, de uma lei moral imutável e de uma dignidade humana que transcende o Estado e o consenso social, imuniza a civilização contra o relativismo e o igualitarismo nivelador do marxismo cultural.
Além disso, o cristianismo é uma tradição milenar, profundamente enraizada no cotidiano das pessoas, não sendo uma novidade a ser imposta ou implementada, mas uma força presente há séculos, que permeia a estrutura social, moral e cultural da sociedade. Sua presença constante nas comunidades, desde os tempos mais antigos, oferece uma resistência robusta contra qualquer tentativa de subverter a ordem natural e moral estabelecida.
Não por acaso, tanto Karl Marx quanto Antonio Gramsci identificaram no cristianismo o principal obstáculo à realização de seus projetos revolucionários. Marx chamou a religião de "ópio do povo" porque sabia que uma alma ancorada em Deus não se submete facilmente ao poder terreno; Gramsci, mais sutil, propôs a destruição da cultura cristã como pré-condição para o triunfo do socialismo. Sem essa âncora transcendente, a sociedade torna-se presa fácil das engenharias sociais que pretendem redefinir arbitrariamente o homem, a família e a liberdade.
Conclusão
O libertário anticristão, consciente ou não, nega as fundações mesmas do edifício que habita. Ao rejeitar o cristianismo, cava o abismo sob os próprios pés, privando o ideal libertário de sua base moral, cultural e racional. Ele defende a ética voluntária, a liberdade individual e a ordem espontânea, mas sem o solo metafísico e histórico que torna esses princípios inteligíveis e possíveis. É um erro tentar preservar a liberdade em termos absolutos sem reconhecer as raízes cristãs que a sustentam, pois o cristianismo é a única tradição que a legitima e a viabiliza.
Negar o cristianismo é racionalmente insustentável. A liberdade, como a conhecemos, é filha da fé cristã, que oferece a base moral e metafísica que torna a liberdade tanto desejável quanto possível. Mesmo que ateu, o libertário que ama a liberdade deveria, no mínimo, respeitar — e, idealmente, redescobrir — essas raízes cristãs. Pois sem fé, restam apenas o niilismo e o relativismo, que, eventualmente, desaguam na servidão.
Como nos ensina a tradição: Ubi fides ibi libertas — onde há fé, há liberdade.

Apache Kafka Architecture
Apache Kafka is a powerful distributed stream processing platform originally developed by LinkedIn, written in Scala and Java. In this article, I walk through the foundational concepts, design and architecture, concluding with hands-on coding examples using Node.js and the KafkaJS library.
Introduction to Kafka
Kafka enables the processing of real-time data streams in a distributed and scalable manner. It’s widely used in systems requiring reliable communication between components, especially for event-driven architectures and microservices.
However, these words sounds very markety and I like to deconstruct things to its basic first principles so that is what I’m going to do. This guide outlines the essential components, explains the core concepts like brokers, producers, consumers, and topics, and dives into more complex abstractions like partitions, consumer groups, and Kafka’s distributed nature.
Kafka Core Components
Here we discuss the fundamental components of Kafka.
Topics and Messages
Messages in Kafka are organized into logical categories called topics. Each topic is append-only and immutable (ie you cannot go back and edit a message). New data is added sequentially at the end. Disks love that.
There are two topics, one called users with two messages (John and Ed) and a Jobs with two messages Req1 and Req2.
Kafka Broker (Server)
The central server that receives and stores messages sent by producers and allow consumers to read the messages. Clients communicate with brokers via TCP, typically on port 9092.
Kafka broker hosts the topics and messages.
Producers and Consumers:
Producers connects to a broker, sends messages to the Kafka broker by specifying the topic.
Publisher pushes messages to the broker for a topic, messages go to the end.
Consumers connects to a broker, polls messages from a topic for a given broker for processing.
Customer polls messages based on a position
Partitions
I always say the best way to work with billions of rows is to avoid working with billions of row. Kafka is no different.
The topics in Kafka can be divided into partitions to allow data distribution and scalability. Each partition acts as a log that consumers read sequentially. Messages within partitions are identified by their offset, which is the message’s position in the log.
Partitioning
Partitioning enables parallel processing, you can have two consumers each processing a partition in parallel. While this allows scaling and improve reading throughput, it introduces complexity as producers and consumers must be aware of partitioning logic. A topic may have multiple partitions based on partition keys (e.g., A–M in partition 0, N–Z in partition 1).
Pub/Sub vs Queue Model
Kafka supports both pub/sub and queue-based messaging patterns:
- Queue: The topic can be treated as a queue, ie any message published to the queue will be consumed only once and popped from the queue. No two consumers can get the same message.
- Pub/Sub: The topic can be in publish-subscribe entity, ie any message published to the topic can be consumed by different consumers.
Kafka achieves this dual functionality using consumer groups. Each consumer in a group is assigned specific partitions, ensuring messages are processed only once per group.
To simulate a queue , all consumers are placed in the same consumer group (they all have the same group name). Whereas to simulate pub/sub mode you would place all consumers in unique group names.
Consumer Groups and Rebalancing
Each partition in a topic is assigned one consumer in a group. When multiple consumers join the same group, Kafka rebalances partitions among them. Each partition is consumed by only one consumer in a group. This allows horizontal scaling while ensuring order within each partition is maintained. Will demonstrate that in the code section.
Distributed Kafka Clusters and Zookeeper
Kafka operates as a distributed system with multiple brokers. Each broker can be a leader or follower for different partitions. The leader handles reads and writes, while followers replicate data.
Kafka originally relied on Zookeeper to manage broker coordination, metadata, and leader election. Zookeeper tracks which broker is the leader of which partition. However, Zookeeper introduces complexity and is being phased out in newer Kafka versions. Kafka 4.0 no longer has Zookeeper.
On Long Polling
You may ask, how does the consumer get the data the moment it is published to the topic/partition? I encourage you to first think of how could this be implemented.
One approach is push, ie the broker pushes the message to the consumer TCP connection. This approach is real-time, but overwhelms the consumer, as it needs to process the message.
Another approach is polling, ie the consumer every X milliseconds asks the broker, is there anything for me and the broker replies, yes here you go, or no nothing, this approach does allow the consumer to read at its own pace but may introduce severe network chatter, which lead to network bandwidth, it also may causes consumer to miss the real-time message, since the message may have came in to the broker between polls.
The final approach which Kafka went with is long polling which I talked extensively on my backend course. The consumer connects to the broker and sends a normal poll, if there is a message the broker replies back, if there isn’t the broker doesn’t respond with “no”, but instead just wait little bit more (configurable), this increases the chances that messages may arrive during this wait. Once we get a message the broker writes the response. Meanwhile the consumer feels like its poll request just took little longer.
Kafka, Docker and Node Example
We will use docker to install Kafka broker and Zookeeper single mode cluster. Then create a topic called “Users” with two partitions, produce some messages on both partitions and have consumers read from the partitions.
My docker host IP is 192.168.7.179, replace it with your own docker host IP.
You will need to have docker and Node installed to proceed
First we clone the repo and change IP address to your docker host.
```javascript
clone the repo
git clone https://github.com/hnasr/javascript_playground.git
change to the kafka directory
cd javascript_playground/kafka
edit docker-compose.yml, producer.js, topics.js and consumer.js change the 192.168.7.179 with your docker host ip.
cat starthere.txt ```
Spin up Zookeeper and Kafka containers using Docker commands.
```javascript services: zookeeper: image: zookeeper hostname: zookeeper ports: - 2181:2181 volumes: - zookeeper_data:/data - zookeeper_datalog:/datalog
kafka: image: ches/kafka restart: always hostname: localhost ports: - "9092:9092" environment: KAFKA_ADVERTISED_HOST_NAME: 192.168.7.179 ZOOKEEPER_IP: 192.168.7.179 KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1 ALLOW_PLAINTEXT_LISTENER: 1 depends_on: - zookeeper volumes: - kafka_data:/kafka
volumes: zookeeper_data: zookeeper_datalog: kafka_data: ```
javascript docker-compose up
Create a topic called
MyUsers
with two partitions, we will use kafkajs module to connect to the kafka broker.```javascript //const Kafka = require("kafkajs").Kafka const {Kafka} = require("kafkajs")
run(); async function run(){ try { const kafka = new Kafka({ "clientId": "myapp", "brokers" :["192.168.7.179:9092"] })
const admin = kafka.admin(); console.log("Connecting.....") await admin.connect() console.log("Connected!") //A-M, N-Z await admin.createTopics({ "topics": [{ "topic" : "MyUsers", "numPartitions": 2 }] }) console.log("Created Successfully!") await admin.disconnect(); } catch(ex) { console.error(`Something bad happened ${ex}`) } finally{ process.exit(0); }
} ```
javascript node topics.js
Produce some messages with a producer, the messages are user names. I have the messages starting with letters
```javascript //const Kafka = require("kafkajs").Kafka const {Kafka} = require("kafkajs") const msg = process.argv[2]; run(); async function run(){ try { const kafka = new Kafka({ "clientId": "myapp", "brokers" :["192.168.7.179:9092"] })
const producer = kafka.producer(); console.log("Connecting.....") await producer.connect() console.log("Connected!") //A-M 0 , N-Z 1 const partition = msg[0] < "N" ? 0 : 1; const result = await producer.send({ "topic": "Users", "messages": [ { "value": msg, "partition": partition } ] }) console.log(`Send Successfully! ${JSON.stringify(result)}`) await producer.disconnect(); } catch(ex) { console.error(`Something bad happened ${ex}`) } finally{ process.exit(0); }
} ```
javascript node producer.js Adam node producer.js Zack
javascript HusseinMac:kafka HusseinNasser$ node producer.js Adam Connecting..... Connected! Send Successfully! [{"topicName":"MyUsers","partition":0,"errorCode":0,"offset":"0","timestamp":"-1"}] HusseinMac:kafka HusseinNasser$ node producer.js Zack Connecting..... Connected! Send Successfully! [{"topicName":"MyUsers","partition":1,"errorCode":0,"offset":"0","timestamp":"-1"}]
Implement a consumer that subscribes to the topic and handles messages with long polling.
Note that I hard coded a consumer group name “test” in the consumer.js file. Running the consumer.js file will create a new consumer on the MyUsers topic and it will be responsible for both partitions. You can note this from the response"memberAssignment”:{“MyUsers”:[0,1]}
javascript HusseinMac:kafka HusseinNasser$ node consumer.js Connecting..... Connected! {"level":"INFO","timestamp":"2025-04-13T14:29:36.102Z","logger":"kafkajs","message":"[Consumer] Starting","groupId":"test"} {"level":"INFO","timestamp":"2025-04-13T14:29:58.411Z","logger":"kafkajs","message":"[Runner] Consumer has joined the group","groupId":"test","memberId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","leaderId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","isLeader":true,"memberAssignment":{"MyUsers":[0,1]},"groupProtocol":"RoundRobinAssigner","duration":22307} RVD Msg Adam on partition 0 RVD Msg Zack on partition 1
Now assume we run another consumer, which will also have the same group. Kafka will rebalance the group and assign a partition for each consumer so they parallel process.
Note the memberAssignment property for each consumer.
```javascript HusseinMac:kafka HusseinNasser$ node consumer.js (consumer 1) {"level":"ERROR","timestamp":"2025-04-13T14:31:09.360Z","logger":"kafkajs","message":"[Connection] Response Heartbeat(key: 12, version: 0)","broker":"192.168.7.179:9092","clientId":"myapp","error":"The group is rebalancing, so a rejoin is needed","correlationId":39,"size":6} {"level":"ERROR","timestamp":"2025-04-13T14:31:09.361Z","logger":"kafkajs","message":"[Runner] The group is rebalancing, re-joining","groupId":"test","memberId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","error":"The group is rebalancing, so a rejoin is needed","retryCount":0,"retryTime":308} {"level":"INFO","timestamp":"2025-04-13T14:31:09.382Z","logger":"kafkajs","message":"[Runner] Consumer has joined the group","groupId":"test","memberId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","leaderId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","isLeader":true,"memberAssignment":{"MyUsers":[1]},"groupProtocol":"RoundRobinAssigner","duration":21}
HusseinMac:kafka HusseinNasser$ node consumer.js (consumer 2) Connecting..... Connected! {"level":"INFO","timestamp":"2025-04-13T14:31:07.599Z","logger":"kafkajs","message":"[Consumer] Starting","groupId":"test"} {"level":"INFO","timestamp":"2025-04-13T14:31:09.383Z","logger":"kafkajs","message":"[Runner] Consumer has joined the group","groupId":"test","memberId":"myapp-6c861d03-879d-4b7b-81a1-1e2cd1c15c83","leaderId":"myapp-901679c6-034c-4efd-bc4d-cb5fc5bc9e6e","isLeader":false,"memberAssignment":{"MyUsers":[0]},"groupProtocol":"RoundRobinAssigner","duration":1783} ```
Let us publish one message for each partition and see what happens.
javascript node producer.js Adamy node producer.js Zackery
```javascript (consumer 1) RVD Msg Zackery on partition 1 (consumer 2) RVD Msg Adamy on partition 0
```
What happens if more consumers than partitions are available? As per testing, new consumers won’t get any partitions assigned. But a consumer group rebalance may reassign partitions.
Kafka Pros and Cons
By understanding the architecture and design of Apache Kafka we know the fact it is performs well for writes (producing messages), because of the append-only nature. And having the consumer aware of the position to where to read from makes reads also fast. Kafka scales well with partitioning and handle fault tolerant with the distributed nature.
However, no software is free of limitations, with all these features added to Kafka, complexity is unavoidable. Producers needs to be aware of the partitions which introduces complexity in producing messages. The need for distributed architecture, replication introduces depedancies on an external component (Zookeeper) which adds more complexity and even latency. All of this makes Kafka difficult to install, maintain and manage.
Note that Kafka 4.0 that was release in March 2025 has completely removed Zookeeper in favor of a raft based replication between brokers.
Conclusion
Now that you know the basics of Apache Kafka, you will understand its power and its limitations. That is the most important thing. Anything on top of Kafka uses these fundamentals.

2025-05-17 07:16:05一、WhatsApp 登录为何在中国大陆必须开启蜂窝数据?
在中国大陆,用户尝试使用香港 SIM 卡登录 WhatsApp,发现即使设备:
- 开启了国际漫游;
- 连接 Wi-Fi 并开启了 VPN;
- 能正常接收 SMS 和电话;
但如果蜂窝数据关闭,WhatsApp 登录界面将无法进入“发送验证码”步骤,只显示提示或错误。 而一旦开启蜂窝数据(即使不开流量),验证码便能顺利发送,注册或登录成功。
这种现象是 WhatsApp 的安全机制刻意设计的结果,而非 Bug 或网络问题。
WhatsApp 官方帮助文档明确指出:
“必须将 SIM 卡插入设备,并能接收 SMS 或电话。” — WhatsApp Help Center【来源¹】
这说明 WhatsApp 强烈依赖 SIM 卡与蜂窝网络处于“活跃状态”,而不仅仅是“能接收短信”。
在中国等 WhatsApp 被屏蔽的国家,很多短信可能被运营商过滤掉,因此 WhatsApp 更依赖**蜂窝数据链路是否建立(即 PDP Context)**来判断号码是否真实存在于设备中。
二、WhatsApp 的运营商验证机制(Carrier-Based Verification)
除了常见的短信验证码,WhatsApp 实际上采用了多个层次的 SIM 验证机制,确保账号属于 SIM 实际持有者:
2.1 使用蜂窝数据进行 SIM 探测(SIM Check)
WhatsApp 在部分地区可通过运营商自动验证手机号,无需输入验证码。流程如下:
- App 通过蜂窝数据向 WhatsApp 与运营商合作的验证端口发送网络请求;
- 运营商通过 IMSI 或号码确认设备与手机号匹配;
- 后台完成验证后,用户无需再输入任何验证码。
这需要设备具备蜂窝数据网络通道,若关闭数据或无 PDP 上下文,验证即失败。
2.2 闪电通话验证(Flash Call)
WhatsApp 在 Android 中支持 Flash Call 功能:
- 向用户号码拨打一个自动电话;
- 电话立即挂断;
- App 读取通话记录确认该电话已到达;
- 无需手动输入验证码。
这仍然依赖 SIM 卡和运营商语音网络,但无需用户交互。
2.3 登录状态缓存或 Meta 账户共享验证
在某些场景下,WhatsApp 可通过:
- iCloud/Google Drive 中保存的状态;
- 或与 Meta 其他服务(如 Facebook/Instagram)共享的登录状态;
跳过重新验证,但这同样建立在 SIM 持有 + 数据验证成功之后。
三、Telegram 的验证模型:灵活但不绑定 SIM
Telegram 的账号同样基于手机号,但验证方式与 WhatsApp 有本质区别:
3.1 登录只依赖验证码(OTP)
- Telegram 首选将验证码通过 应用内发送(发送至你其他已登录的 Telegram 设备);
- 若没有其他已登录设备,才通过 SMS 或语音电话发送;
- 一旦输入验证码,Telegram 就认为你是账号持有人,无需验证 SIM 是否存在。
3.2 多设备并行,无需 SIM 常驻
Telegram 允许:
- 同时登录多个设备(手机、平板、电脑);
- 旧设备持续保留登录状态;
- 登录新设备无需原设备确认,只要输入验证码即可。
3.3 风险点:验证码即=身份认证
- 若攻击者通过 SIM 交换、接码平台、或拦截短信拿到验证码,就可以登录;
- 登录不会强制登出原设备;
- 用户可能不察觉账号已被并发登录;
- 除非启用“两步验证密码”,否则没有额外防护。
四、Telegram vs WhatsApp:安全性对比
| 特性 | WhatsApp | Telegram | | ------------ | ------------------- | --------------------- | | 是否绑定蜂窝网络 | 是(必须有活跃蜂窝数据) | 否(可 Wi-Fi 登录,甚至无 SIM) | | 是否检测 SIM 活跃性 | 是(PDP context 验证) | 否 | | 是否多设备并行登录 | 否(新设备登录踢出旧设备) | 是(多个设备可共存) | | 被攻击后能否隐藏登录 | 难(原设备立即被登出) | 易(原设备仍在线,攻击者后台可读写) | | 聊天记录是否同步 | 否(仅本地或云备份) | 是(云同步,攻击者可取回全部历史记录) | | 默认加密类型 | E2EE(端到端加密,含密钥变更通知) | 服务器加密(非默认端到端) | | 是否提醒安全代码更改 | 是(联系人收到通知) | 否(无密钥通知机制) | | 是否可完全匿名注册 | 否 | 是(支持区块链匿名号) |
五、结论:谁更能证明“你就是你”
- WhatsApp 的设计重点在于验证 SIM 持有 + 设备绑定 + 网络存在性;
- Telegram 的设计重点在于灵活登录 + 多设备同步 + 匿名性;
- 从“消息是否由本人发送”的角度看,WhatsApp 更强:
WhatsApp 要求设备具备活跃蜂窝数据通道,是为了防止:
- 接码网站注册攻击;
- SIM 不在场的远程登录;
- 虚拟手机号批量刷号;
- SIM swap 后自动登录并伪装真实用户。
Telegram 虽支持 2FA,但默认机制更依赖用户自我防范。
六、推荐使用场景
- ✅ 使用 WhatsApp:当你关心消息的真实性、身份不可伪造、历史无法被取回。
- ⚠️ 使用 Telegram:适合轻量社群沟通,但不建议用于密钥、合同、政务通信。

2025-05-17 01:44:35This article is a repost, migrating from Substack
Introduction
Released in November 2020 by fiatjaf, Nostr is an open, decentralised, censorship-resistant messaging protocol. The protocol is well designed, and many authors have written extensively about the mechanics and use-cases. For the purposes of this article, I will narrow the focus to Nostr as a tool to enable the creation of platform markets. My aim is to give the reader an introduction to platform market pricing and provide concrete steps to price their platform strategically.
What is a Platform Market?
A platform market consists of multiple groups of users who want to interact but can’t do so directly. The platform brings them together to enable interaction, benefiting all users and the platform itself by enabling these interactions and pricing appropriately. Although platform markets have been around forever, the last decade has seen an explosion in their number due to the ubiquity of the internet.
Examples:
· Google
· YouTube
· TV
· Facebook
· Twitter (X)
Platform markets have historically earned significant revenue if they design their pricing correctly. This is because platform markets don’t need to produce goods themselves; rather, one or more “sides” of the platform produce goods and services for the other side, with the platform merely enabling the exchange. TikTok is a prime example: it produces nothing except a video hosting service, with users generating all the content for other users. Effectively, the platform has only fixed costs and very low marginal costs.
Therefore, platform markets are far more scalable than traditional one-sided markets, as their primary concern is to attract as many users as possible (who have no marginal cost to the platform). Additionally, platforms often enjoy a captive audience, making it difficult for competitors to entice away users once they are established. This is particularly evident in software and payment platforms.
How Does Nostr Enable the Creation of Platform Markets?
· Open Protocol: Like the internet, Nostr is an open protocol.
· Inbuilt Payment Systems: Nostr integrates payment systems such as Bitcoin’s Lightning Network.
· Existing User Base: It already has a growing user base.
· Decentralisation: This feature acts as a moat against competitors.
Types of platform enabled by Nostr
As of 2024 we are seeing multiple types of platforms that Nostr has enabled. The first is Nostr relays. A Nostr relay is a simple server that receives and broadcasts user notes (messages) in the Nostr protocol. Users can publish and fetch notes across multiple relays. Nostr relays can be configured by their operator to curate content on specific topics or people. Alternatively, they can be configured with an algorithm as experienced by users of contemporary social media. These can be valuable for users. And potentially, paid relays are a viable business opportunity.
The second platform Nostr enables is the Nostr client. Nostr clients are analogous to internet browser software. Historically, we have seen users be charged to install an internet browser, though this is unlikely to emerge in the market for Nostr clients. As a platform, a Nostr client might be bundled with a relay service (with curation or algorithm).
The third type of platform is Nostr apps. Each app can be designed as a platform if that is valuable for users. We are already seeing Nostr-based alternatives for music and video streaming, looking to compete with apps like YouTube.
We can’t know what the future will hold but the possibilities for designing platforms with Nostr are many. The advantage in designing a platform is that you can create a two sided market.
What is a Two-Sided Market?
All two-sided markets are platform markets, but not all platform markets are two-sided markets. The critical aspect of a two-sided market is that the volume of interactions on the platform depends on both the relative prices charged to each side and the total price charged. This is the case when both sides value more users on the other side, known in literature as an “indirect network externality.”
An example of a one-sided platform market is a clothes retailer, where the volume of sales depends only on the total price, not the relative prices charged to buyers and producers. Conversely, YouTube is a two-sided market where both creators and watchers benefit from more users. Watchers benefit from more variety and quality, while creators benefit from more users and views. YouTube introduces a special category of creators, the advertisers, who benefit monetarily from views because consumers viewing their content are likely to purchase their goods.
The prices paid by YouTube users are not all monetary:
· Watchers are charged an inconvenience fee in the form of advertisements.
· Advertisers are charged a monetary fee.
· Creators are not charged any fees.
Let’s assume the total fees for YouTube add up to $100. Say advertisers are charged $90, watchers face an inconvenience worth $10, and creators still enjoy $0 costs. In this scenario, the total volume of videos watched might be some number like 100,000.
Assume we change the price structure to advertisers being charged $80, watchers paying an inconvenience worth $10, and creators being charged $10 (keeping the total fees at $100). In this new scenario, the likely outcome is that the marginal creator will no longer create videos, and thus, the total volume of videos watched will fall.
Two-Sided Markets that Allow Money Exchange
The key to understanding Nostr’s value lies in its inbuilt payment mechanism—Bitcoin’s Lightning Network protocol. Although this protocol is not part of the Nostr codebase, the existing Nostr clients incorporate it to allow users to pay each other bitcoin with a simple user interface. This means that Nostr as a protocol is ideal for creating platforms where users can exchange monetary value. The mechanics and design choices of the Lightning network further augment Nostr’s value proposition more so than traditional payment systems like credit cards, PayPal, etc.
Key Problem: Chicken and Egg
So far, we have established that platform markets enable at least two groups of users to come together and exchange. The primary problem is that both groups will only use the platform if the other group is already using it, creating a classic chicken and egg scenario. Platforms operate by bringing groups of users together, making users reticent to switch to a new platform because they don’t know if the other users will be there. This gives existing platforms enormous power.
Guy Swann sums this up well in this Nostr note: note1695j0czewtkfwy7h4ne7k2ug706uwc7lendsq50prsfp8vwq8nfszdx4z7.
Competing with Existing Platforms: Divide and Conquer!
To compete with existing platforms, you need to divide and conquer. The original formulation for this strategy is given in both Caillaud and Jullien (2003) and Armstrong (2006). To take advantage of the indirect network externalities identified earlier, the divide and conquer strategy involves subsidising one side of the market to attract a large user base (the "divide" part) and then monetising the other side of the market (the "conquer" part).
Divide: Attract one side of the market by offering lower prices or subsidies. For example, offer free registration to one side. This subsidy is essential to kickstart the network effects, as a larger user base on one side increases the platform’s attractiveness to the other side. This was observed in the early days of YouTube, which was free for both creators and watchers.
Conquer: Once a substantial user base is established on the subsidised side, charge higher fees on the other side of the market. This can be seen in contemporary YouTube, where advertisers (a specific kind of creator) pay fees, and watchers deal with the inconvenience of watching ads (inconvenience is a non-price fee).
Implementing This Strategy in Your Platform:
So who are are you dividing, who are you conquering? Deciding which side to subsidise involves understanding which side offers more benefit to the other side. For example, in nightclubs (Wright, 2004), men and women go to interact. Men are assumed to gain more from each woman’s presence than vice versa, so nightclubs often subsidise women with free entry or drinks to attract men.
First, consider all your user groups. What brings them to your platform, what do they want to gain by interacting with the other user groups.
Think about, and identify, which group confers more value for the other group by being on the platform.
Then, think about how you can subsidise that user group. Free access is common. But Nostr allows seamless payment integration which encourages users to exchange money. A potential model for your platform could be that you charge a fee to both users based on how much value they send to each other. One way to subsidise users in this case is to reduce those fees.
Alternatively, you could pay users to join your platform using Nostr’s integration with the Lightning Network.

2025-05-17 09:54:39Because Bitcoin operates outside traditional financial and political systems, engaging with it can create cognitive dissonance.
This uneasy tension is felt in the space between a lifetime of systemic conditioning and the reality of a protocol that functions beyond anything we have ever known.
Bitcoin challenges deeply ingrained assumptions about what money is, who should control it, and how trust is established in society.
Many initially reject it because Bitcoin breaks the mental models we’ve relied on for understanding value, authority, and trust.
It’s not just adopting a new system; it’s detaching from the old one and any -ism we may personally identify with.
Before we dive in I would like to make an important note about our current system.
Modern Fiat is Not Capitalism
Capitalism is an economic system in which private individuals or businesses own and control the means of production, distribution, and exchange of goods and services, rather than the state.
The main features of this system are limited government intervention, a free market economy, and competition.
While we may believe we live in a capitalistic society, reality is very different:
-
Governments Intervention: Governments intervene in free markets primarily through monetary expansion (money printing) and capital controls.
-
Inflation and Redistribution: Printing increases the money supply, causing inflation that erodes purchasing power unevenly. Those who receive new money first gain at the expense of later recipients. Capital controls restrict market flows, distorting asset and currency prices.
-
Cantillon Effect and Concentration: These mechanisms concentrate wealth and economic power among government insiders and favored corporations, who gain preferential access to resources. This leads to growing government influence and corporate monopolies.
-
Systemic Distortions: Such interventions stifle innovation, reduce market competition, and undermine price signals essential to free market functioning.
-
Therefore: Our modern fiat monetary system is not free market capitalism.
To quote Jeff Booth, from first principles:
> “In a free market, prices fall to the marginal cost of production; if they are not falling, we do not live in a free market. Communism and capitalism are the same system under manipulated money.”
Bitcoin is the first opportunity for humanity to experience a true free market where prices fall—a reality beyond fiat altogether.
Let’s explore how Bitcoin differs from fiat-based systems and economic theories.
Bitcoin vs. Major -isms
| Feature | Capitalism | Communism | Libertarianism | Bitcoin | | ------------------------- | ------------------------------------ | ----------------------------------------- | ------------------------------------ | ------------------------------------------------- | | Ownership Model | Private, profit-driven | Collective, state-owned | Private, voluntary exchange | Individual, self-sovereign | | Control of Money | Central banks & private institutions | State-controlled | Privatized or gold-backed | Decentralized, algorithmic issuance | | Value Flow | Favors asset owners | Centralized and controlled redistribution | Market-driven | Distributed to all network participants | | Ideological Basis | Market efficiency, competition | Class struggle, equality | Individual freedom, non-intervention | Neutral protocol, transparency, free market | | Governance Structure | Market and government interplay | Centralized planning | Minimal state | Consensus among decentralized nodes | | Inflation Policy | Targeted via central banking | Controlled by state | Opposed to fiat inflation | Hard-capped supply: 21 million BTC | | Censorship Resistance | Low to moderate (depends on regime) | Low | Medium, still requires trust | Very high—no central chokepoint | | Accessibility | Varies by class and location | Controlled by state allocation | Varies by market access | Global, permissionless | | Moral Foundation | Efficiency and growth | Equity and solidarity | Autonomy and property rights | Mathematical integrity, sovereignty, transparency |
Bitcoin is not an -ism or a fiat system.
I don't see it as a way to make more fiat paper money either.
It’s a system outside the system that breaks all of our previous mental models.
A truly interdependent reality where the creativity, productivity, gifts, talents, and abilities of one serves all.
Sovereign individuals in service of the collective and vice-versa.
The Difficulty Categorizing Free Thinkers
In different conversations, and while discussing Bitcoin with non-Bitcoiners, I’ve been asked if I am an anarchist, capitalist, communist, liberal, or a libertarian.
Since I don’t identify with any political leaning or traditional ideology, I was sincerely confused when this first started happening—but now I see why.
Bitcoiners are notoriously difficult to place into political categories because their convictions often cut across traditional ideological boundaries.
To the outside observer, this can appear contradictory: a Bitcoiner might criticize the Federal Reserve like a libertarian, value personal personal sovereignty like an anarchist, and believe in sound money like a gold-standard capitalist.
These labels, however, fail to capture the deeper thread—I believe our views are aligned with a protocol in service of humanity, and shaped by a shared belief in a system that values humans rather than fiat-based incentives.
Bitcoin challenges the default left/right binary and exposes just how much our frameworks are built around centralized systems, division, and control.
When those systems are removed—as they are in Bitcoin—any traditional world view falls apart, along with all the labels and polarization that come with it.
To some, this may be why Bitcoiners seem ‘radical’ or ‘religious,’ because we have stepped outside their frame of reality entirely.
This protocol is not a revolution in the name of an ideology—it’s a revolution in the absence of one known to modern history.
Unlearning the Past, Embracing the Now
What makes Bitcoin truly disruptive isn’t just its technology—it invites us to question assumptions we didn’t even know we were making.
I still catch myself trying to compare Bitcoin to a "known" sometimes in this ongoing process of unlearning.
I think part of this evolution is catching myself and remembering, we are at the forefront of a new reality.
Our individual choices and actions are shaping what the post-fiat world will look like.
While for some, this will feel empowering and exciting, for others, this shift can feel unsettling, even threatening, as it calls into question the stability of the familiar.
This is one of the reasons why I see Bitcoin as being the initiator of an individual and collective spiritual awakening.
I can only encourage you to embrace the change—be the change—a powerful manifestor ushering in a new paradigm ✨

2025-05-14 06:48:45Has the architect Greg Chasen considered it when rebuilding the house just one year before the catastrophe? Apparently not! Another of his projects was featured on the Value of Architecture as properties with design integrity.
This is a super interesting subject. The historic character, livability, and modern disaster-resistance is a triangle where you often have to pick just one or two, which leads to some tough decisions that have major impacts on families and communities. Like one of the things he mentions is that the architect completely eliminated plants from the property. That's great for fire resistance, but not so great for other things if the entire town decides to go the same route (which he does bring up later in the video). I don't think there's any objectively right answer, but definitely lots of good (and important) discussion points to be had.

2025-05-17 03:21:54ยังมีเรื่องราวของน้ำตาล และ เซลล์ มาคุยกันต่อนะครับ เพราะยังมีคนสงสัยอยู่ว่า เอ้ย ตกลงต้องห่วงการ Spike&Staylong ของอินซุลินอยู่หรือเปล่า แล้วถ้าเราไม่ spike&staylong ก็คือกินคาร์บเบาๆตลอดวันได้เลยใช่ไหมก็มันไม่ spike&staylong แล้วนี่ โอเคครับ เรามาเปิดผับกันอีกครั้ง
คราวก่อนนั้นเราคุยกันเรื่อง ผับน้ำตาลกันไปแล้วนะครับว่า เมื่ออินซูลิน spike สูง และค้างนาน เหมือนเปิดผับแล้ววัยรุ่นแห่กันเข้ามาเที่ยว จนพีอาร์เมาจัด
เผื่อใครจำไม่ได้ ย้อนให้นิดๆครับ ว่าให้ลองนึกภาพว่าเฮียเปิดผับอยู่ดี ๆ ลูกค้าหลั่งไหลเข้ามารัว ๆ เหมือนมีโปรเบียร์ 1 แถม 10 ตอนสามทุ่ม ทุกโต๊ะสั่งข้าวเหนียวหมูปิ้งพร้อมเบียร์น้ำแข็งเต็มโต๊ะ นักเที่ยวก็ยังแห่เข้าผับแบบไม่มีพัก อินซูลินซึ่งเป็นเหมือน “พีอาร์” ที่ต้องจัดการรับแขก (หรือรับน้ำตาลเข้าสู่เซลล์) ก็เลยต้องทำงานหนักแบบ non-stop
อินซูลินเป็นฮอร์โมนสำคัญที่ช่วยเอาน้ำตาลในเลือดเข้าไปเก็บในเซลล์ ถ้า spike ทีเดียวสูงมาก เซลล์ก็รีบดูดน้ำตาลเข้าไปเต็มที่จนเกินพิกัด เหมือนผับที่แน่นจนปิดประตูไม่ลง
ถ้าเหตุการณ์แบบนี้เกิดขึ้นบ่อย ๆ ร่างกายจะเริ่มรู้สึกว่า “ทำไมอินซูลินถึงต้องออกมาบ่อยขนาดนี้วะ?” ระบบก็เริ่มปิดรับแขก เซลล์เริ่มไม่อยากตอบสนอง เพราะมันเหนื่อย มันชิน และมันก็เริ่ม “ดื้ออินซูลิน”
ผลที่ตามมาเมื่อ spike สูงและค้าง สิ่งที่ตามมา... คือความปั่นป่วนในร่างกายอย่างต่อเนื่อง น้ำตาลลอยค้างในเลือด ไปจับกับโปรตีนจนกลายเป็นเจ้า AGEs ตัวร้าย ไขมันก็ถูกสร้างมากขึ้น ล้นเข้าไปสะสมในตับ ในพุง ในซอกที่ร่างกายไม่รู้จะเก็บไว้ตรงไหนแล้ว สมองก็เบลอ ใจวูบ ง่วงงุน... เหมือนเข้าเวรประชุมยาวแบบไม่มีกาแฟ ฮอร์โมนที่เคยเป็นทีมงานสามัคคี ก็เริ่มทะเลาะกันเอง อินซูลินงอน leptin งง ghrelin งวย
แล้วถ้าเราไม่ spike แต่กินคาร์บจุ๋มจิ๋มทั้งวันล่ะ? พอรู้ว่าการเปิดผับแจกคาร์บแบบจัดหนักไม่ดี หลายคนก็ปรับกลยุทธ์ใหม่ มาแนวสายสุขุมว่า “งั้นเปิดผับแบบเนิบ ๆ ก็แล้วกัน… ไม่จัดปาร์ตี้ใหญ่ แต่มีแขกแวะเข้ามาทั้งวัน” ฟังดูดีใช่ไหม? แต่เอาเข้าจริง มันเหนื่อยไม่แพ้กันเลย
ลองนึกภาพว่าประเทศไม่มีเคอร์ฟิว เฮียเปิดผับที่มีลูกค้าเดินเข้าออกไม่หยุด ไม่ได้มากันเป็นฝูงแบบรอบโปรโมชั่น แต่มาเรื่อย ๆ แบบชั่วโมงละโต๊ะ สองโต๊ะ พีอาร์ อินซูลิน ก็เลยต้องยืนต้อนรับแขกตลอดเวลา ไม่มีเวลานั่งพัก ไม่มีช่วงเปลี่ยนกะ ไม่มีเวลาปิดไฟเก็บโต๊ะ คือทำงานต่อเนื่องยาว ๆ ตั้งแต่ 8 โมงเช้า ยัน 8 โมงเช้า สุดท้าย ผับก็เปิดไฟยันสว่าง อินซูลินก็กลายเป็นพนักงานกะดึกตลอดชีพ และเมื่อไม่มีเวลา “พักผับ” ระบบหลังบ้านก็ไม่เคยได้ฟื้นฟูเลย
ภาพรวมของการกินจุ๋มจิ๋มทั้งวันแบบนี้นั้น - เผาผลาญไขมันไม่ออกเลย เพราะอินซูลินทำหน้าที่เหมือนไฟบนเวที ถ้ายังเปิดไฟอยู่ “เครื่องดูดไขมันหลังร้าน” มันก็ไม่ทำงาน - แม่บ้านทำความสะอาดก็เข้าไม่ได้ เพราะแขกเดินเข้าเดินออกตลอด ระบบกำจัดที่ควรจะได้ล้างของเสียในเซลล์ ก็เลยโดนขัดจังหวะตลอด - พนักงานเหนื่อยสะสมจากงานไม่มีหยุด ทำให้เกิดความเครียดสะสมในร่างกาย ฮอร์โมนรวน อารมณ์ก็แปรปรวนง่ายขึ้น หิวเก่งขึ้น ทั้งที่เพิ่งกินไป
เปิดผับแบบคึกคักจัดเต็มทีเดียว แล้วปิดยาว หรือ เปิดทั้งวันแบบไม่มีช่วงปิด สุดท้ายพังทั้งคู่
ทีนี้เราน่าจะพอเห็นภาพร่างคร่าวๆ ของการบริหารการจัดการน้ำตาลในตัวเราได้แล้วนะครับ ว่าจะไดเอทไหนก็ตาม การบริหารการจัดการฮอร์โมนส์ คือสิ่งสำคัญไม่แพ้เรื่องอื่นๆ แม้จะไม่ใช่เรื่องสำคัญที่สุดในสายตาใครก็ตาม
นี่เป็นเพียงจุดเริ่มต้นการเรียนรู้เล็กๆ ซึ่งเส้นทางสายที่เรียกว่า ร่างกาย มันยังไปไกลอีกลิบลับเลยครับ ไม่ว่าจะจังหวัดคอติซอล จังหวัดพฤกษเคมี จังหวัดพลังงาน จังหวัดสารอาหาร แถมลักษณะร่างกายแต่ละคน ก็เปรียบเหมือนรถต่างยี่ห้อ ต่างน้ำมันขับเคลื่อน ต่างซีซี หรือแม้ว่าจะเหมือนกัน ก็ยังต่างปี ต่างไมล์การขับขี่

2025-05-09 23:10:14I. Historical Foundations of U.S. Monetary Architecture
The early monetary system of the United States was built atop inherited commodity money conventions from Europe’s maritime economies. Silver and gold coins—primarily Spanish pieces of eight, Dutch guilders, and other foreign specie—formed the basis of colonial commerce. These units were already integrated into international trade and piracy networks and functioned with natural compatibility across England, France, Spain, and Denmark. Lacking a centralized mint or formal currency, the U.S. adopted these forms de facto.
As security risks and the practical constraints of physical coinage mounted, banks emerged to warehouse specie and issue redeemable certificates. These certificates evolved into fiduciary media—claims on specie not actually in hand. Banks observed over time that substantial portions of reserves remained unclaimed for years. This enabled fractional reserve banking: issuing more claims than reserves held, so long as redemption demand stayed low. The practice was inherently unstable, prone to panics and bank runs, prompting eventual centralization through the formation of the Federal Reserve in 1913.
Following the Civil War and unstable reinstatements of gold convertibility, the U.S. sought global monetary stability. After World War II, the Bretton Woods system formalized the U.S. dollar as the global reserve currency. The dollar was nominally backed by gold, but most international dollars were held offshore and recycled into U.S. Treasuries. The Nixon Shock of 1971 eliminated the gold peg, converting the dollar into pure fiat. Yet offshore dollar demand remained, sustained by oil trade mandates and the unique role of Treasuries as global reserve assets.
II. The Structure of Fiduciary Media and Treasury Demand
Under this system, foreign trade surpluses with the U.S. generate excess dollars. These surplus dollars are parked in U.S. Treasuries, thereby recycling trade imbalances into U.S. fiscal liquidity. While technically loans to the U.S. government, these purchases act like interest-only transfers—governments receive yield, and the U.S. receives spendable liquidity without principal repayment due in the short term. Debt is perpetually rolled over, rarely extinguished.
This creates an illusion of global subsidy: U.S. deficits are financed via foreign capital inflows that, in practice, function more like financial tribute systems than conventional debt markets. The underlying asset—U.S. Treasury debt—functions as the base reserve asset of the dollar system, replacing gold in post-Bretton Woods monetary logic.
III. Emergence of Tether and the Parastatal Dollar
Tether (USDT), as a private issuer of dollar-denominated tokens, mimics key central bank behaviors while operating outside the regulatory perimeter. It mints tokens allegedly backed 1:1 by U.S. dollars or dollar-denominated securities (mostly Treasuries). These tokens circulate globally, often in jurisdictions with limited banking access, and increasingly serve as synthetic dollar substitutes.
If USDT gains dominance as the preferred medium of exchange—due to technological advantages, speed, programmability, or access—it displaces Federal Reserve Notes (FRNs) not through devaluation, but through functional obsolescence. Gresham’s Law inverts: good money (more liquid, programmable, globally transferable USDT) displaces bad (FRNs) even if both maintain a nominal 1:1 parity.
Over time, this preference translates to a systemic demand shift. Actors increasingly use Tether instead of FRNs, especially in global commerce, digital marketplaces, or decentralized finance. Tether tokens effectively become shadow base money.
IV. Interaction with Commercial Banking and Redemption Mechanics
Under traditional fractional reserve systems, commercial banks issue loans denominated in U.S. dollars, expanding the money supply. When borrowers repay loans, this destroys the created dollars and contracts monetary elasticity. If borrowers repay in USDT instead of FRNs:
- Banks receive a non-Fed liability (USDT).
- USDT is not recognized as reserve-eligible within the Federal Reserve System.
- Banks must either redeem USDT for FRNs, or demand par-value conversion from Tether to settle reserve requirements and balance their books.
This places redemption pressure on Tether and threatens its 1:1 peg under stress. If redemption latency, friction, or cost arises, USDT’s equivalence to FRNs is compromised. Conversely, if banks are permitted or compelled to hold USDT as reserve or regulatory capital, Tether becomes a de facto reserve issuer.
In this scenario, banks may begin demanding loans in USDT, mirroring borrower behavior. For this to occur sustainably, banks must secure Tether liquidity. This creates two options: - Purchase USDT from Tether or on the secondary market, collateralized by existing fiat. - Borrow USDT directly from Tether, using bank-issued debt as collateral.
The latter mirrors Federal Reserve discount window operations. Tether becomes a lender of first resort, providing monetary elasticity to the banking system by creating new tokens against promissory assets—exactly how central banks function.
V. Structural Consequences: Parallel Central Banking
If Tether begins lending to commercial banks, issuing tokens backed by bank notes or collateralized debt obligations: - Tether controls the expansion of broad money through credit issuance. - Its balance sheet mimics a central bank, with Treasuries and bank debt as assets and tokens as liabilities. - It intermediates between sovereign debt and global liquidity demand, replacing the Federal Reserve’s open market operations with its own issuance-redemption cycles.
Simultaneously, if Tether purchases U.S. Treasuries with FRNs received through token issuance, it: - Supplies the Treasury with new liquidity (via bond purchases). - Collects yield on government debt. - Issues a parallel form of U.S. dollars that never require redemption—an interest-only loan to the U.S. government from a non-sovereign entity.
In this context, Tether performs monetary functions of both a central bank and a sovereign wealth fund, without political accountability or regulatory transparency.
VI. Endgame: Institutional Inversion and Fed Redundancy
This paradigm represents an institutional inversion:
- The Federal Reserve becomes a legacy issuer.
- Tether becomes the operational base money provider in both retail and interbank contexts.
- Treasuries remain the foundational reserve asset, but access to them is mediated by a private intermediary.
- The dollar persists, but its issuer changes. The State becomes a fiscal agent of a decentralized financial ecosystem, not its monetary sovereign.
Unless the Federal Reserve reasserts control—either by absorbing Tether, outlawing its instruments, or integrating its tokens into the reserve framework—it risks becoming irrelevant in the daily function of money.
Tether, in this configuration, is no longer a derivative of the dollar—it is the dollar, just one level removed from sovereign control. The future of monetary sovereignty under such a regime is post-national and platform-mediated.

2025-05-17 08:58:14Quando tentamos simplificar/ilustrar algo que é extremamente complexo, pode resultar em algo distorcido. Apesar do resultado sair distorcido, continua a ser a melhor representação, temos é que ter em mente que essa distorção existe quando analisamos essa informação.
O maior exemplo, é o mapa mundi, quando transformamos uma esfera em algo plano, é natural que crie distorções, como quanto mais perto dos polos, os países são sobredimensionados em relação aos que estão mais perto da linha do Equador.
Esta infografia criada pelo Saylor é comumente utilizada, mas esta deve ser utilizada com moderação, porque a informação também está distorcida.
Assim, sempre que alguém utiliza estes dados para fazer análises, deve estar ciente que existem distorções. Primeiro, em alguns ativos os valores são impossíveis de calcular, são apenas estimativas. Já foram feitos vários estudos, e sempre com valores bastantes díspares.
Depois, esta infografia simplifica demasiado, não sendo visível a sobreposição de ativos, por exemplo, as empresas possuem outros ativos, isso significa, que não podemos fazer somas simples. Ou seja, se somarmos as Equities (115T) e os Bonds(300T) não resulta em $415 Triliões de riqueza, o real valor é inferior.
Vamos a dois bons exemplos:
A Berkshire Hathaway, a empresa de Warren Buffett, que o seu atual core business é investir em outras empresas. Apesar de neste momento, ter uma enorme liquidez, está a aguardar pelo momento certo para voltar ao mercado.
A outra empresa é MicroStrategy, que gradualmente está-se a transformar num banco Bitcoin. O seu negócio inicial, começa a ser insignificante, para a sua atual dimensão, está a fazer um percurso muito similar à Berkshire Hathaway, enquanto a Berkshire Hathaway redirecionou o seu negócio para o investimento em ações, a MicroStrategy para o Bitcoin.
Um erro comum entre alguns bitcoiners quando fazem estimativas baseada nesta tabela, é acreditarem que o crescimento do valor do Bitcoin, vai resultar numa redução do valor das Equities. Isso não vai acontecer, porque as empresas também vão possuir Bitcoin na sua tesouraria, logo se o valor do bitcoin subir, as equities também o vão.
Onde o Bitcoin vai certamente impactar, é nas Bonds e no Real Estate.
Assim para concluir, esta infografia é interessante para fazer cálculos ou análises, mas não podemos esquecer que contém distorções.

2025-05-09 13:56:57Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.
Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.
The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.
Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.
The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.
Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.
With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)
To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.
I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?
A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

2025-05-14 06:12:19We asked members of the design community to choose an artifact that embodies craft—something that speaks to their understanding of what it means to make with intention. Here’s what they shared.
A vintage puzzle box, a perfectly tuned guitar, an AI-powered poetry camera. A daiquiri mixed with precision. A spreadsheet that still haunts muscle memory. Each artifact tells a story: not just about the thing itself, but about the choices of the creator behind it. What to refine, what to leave raw. When to push forward, when to let go. Whether built to last for generations or designed to delight in a fleeting moment, the common thread is that great craft doesn’t happen by accident. It’s made.
On the application of craft
Even the most experienced makers can benefit from building structure and intention into their practice. From sharpening your storytelling to designing quality products, these pieces offer practical ways to uplevel your craft.

2025-05-01 21:01:55The arrival of the coronavirus brought not only illness and death but also fear and panic. In such an environment of uncertainty, people have naturally stocked up on necessities, not knowing when things will return to normal.
Retail shelves have been cleared out, and even online suppliers like Amazon and Walmart are out of stock for some items. Independent sellers on these e-commerce platforms have had to fill the gap. With the huge increase in demand, they have found that their inventory has skyrocketed in value.
Many in need of these items (e.g. toilet paper, hand sanitizer and masks) balk at the new prices. They feel they are being taken advantage of in a time of need and call for intervention by the government to lower prices. The government has heeded that call, labeling the independent sellers as "price gougers" and threatening sanctions if they don't lower their prices. Amazon has suspended seller accounts and law enforcement at all levels have threatened to prosecute. Prices have dropped as a result and at first glance this seems like a victory for fair play. But, we will have to dig deeper to understand the unseen consequences of this intervention.
We must look at the economics of the situation, how supply and demand result in a price and how that price acts as a signal that goes out to everyone, informing them of underlying conditions in the economy and helping coordinate their actions.
It all started with a rise in demand. Given a fixed supply (e.g., the limited stock on shelves and in warehouses), an increase in demand inevitably leads to higher prices. Most people are familiar with this phenomenon, such as paying more for airline tickets during holidays or surge pricing for rides.
Higher prices discourage less critical uses of scarce resources. For example, you might not pay $1,000 for a plane ticket to visit your aunt if you can get one for $100 the following week, but someone else might pay that price to visit a dying relative. They value that plane seat more than you.
*** During the crisis, demand surged and their shelves emptied even though
However, retail outlets have not raised prices. They have kept them low, so the low-value uses of things like toilet paper, masks and hand sanitizer has continued. Often, this "use" just takes the form of hoarding. At everyday low prices, it makes sense to buy hundreds of rolls and bottles. You know you will use them eventually, so why not stock up? And, with all those extra supplies in the closet and basement, you don't need to change your behavior much. You don't have to ration your use.
At the low prices, these scarce resources got bought up faster and faster until there was simply none left. The reality of the situation became painfully clear to those who didn't panic and got to the store late: You have no toilet paper and you're not going to any time soon.
However, if prices had been allowed to rise, a number of effects would have taken place that would have coordinated the behavior of everyone so that valuable resources would not have been wasted or hoarded, and everyone could have had access to what they needed.
On the demand side, if prices had been allowed to rise, people would have begun to self-ration. You might leave those extra plies on the roll next time if you know they will cost ten times as much to replace. Or, you might choose to clean up a spill with a rag rather than disposable tissue. Most importantly, you won't hoard as much. That 50th bottle of hand sanitizer might just not be worth it at the new, high price. You'll leave it on the shelf for someone else who may have none.
On the supply side, higher prices would have incentivized people to offer up more of their stockpiles for sale. If you have a pallet full of toilet paper in your basement and all of the sudden they are worth $15 per roll, you might just list a few online. But, if it is illegal to do so, you probably won't.
Imagine you run a business installing insulation and have a few thousand respirator masks on hand for your employees. During a pandemic, it is much more important that people breathe filtered air than that insulation get installed, and that fact is reflected in higher prices. You will sell your extra masks at the higher price rather than store them for future insulation jobs, and the scarce resource will be put to its most important use.
Producers of hand sanitizer would go into overdrive if prices were allowed to rise. They would pay their employees overtime, hire new ones, and pay a premium for their supplies, making sure their raw materials don't go to less important uses.
These kinds of coordinated actions all across the economy would be impossible without real prices to guide them. How do you know if it makes sense to spend an extra $10k bringing a thousand masks to market unless you know you can get more than $10 per mask? If the price is kept artificially low, you simply can't do it. The money just isn't there.
These are the immediate effects of a price change, but incredibly, price changes also coordinate people's actions across space and time.
Across space, there are different supply and demand conditions in different places, and thus prices are not uniform. We know some places are real "hot spots" for the virus, while others are mostly unaffected. High demand in the hot spots leads to higher prices there, which attracts more of the resource to those areas. Boxes and boxes of essential items would pour in where they are needed most from where they are needed least, but only if prices were allowed to adjust freely.
This would be accomplished by individuals and businesses buying low in the unaffected areas, selling high in the hot spots and subtracting their labor and transportation costs from the difference. Producers of new supply would know exactly where it is most needed and ship to the high-demand, high-price areas first. The effect of these actions is to increase prices in the low demand areas and reduce them in the high demand areas. People in the low demand areas will start to self-ration more, reflecting the reality of their neighbors, and people in the hotspots will get some relief.
However, by artificially suppressing prices in the hot spot, people there will simply buy up the available supply and run out, and it will be cost prohibitive to bring in new supply from low-demand areas.
Prices coordinate economic actions across time as well. Just as entrepreneurs and businesses can profit by transporting scarce necessities from low-demand to high-demand areas, they can also profit by buying in low-demand times and storing their merchandise for when it is needed most.
Just as allowing prices to freely adjust in one area relative to another will send all the right signals for the optimal use of a scarce resource, allowing prices to freely adjust over time will do the same.
When an entrepreneur buys up resources during low-demand times in anticipation of a crisis, she restricts supply ahead of the crisis, which leads to a price increase. She effectively bids up the price. The change in price affects consumers and producers in all the ways mentioned above. Consumers self-ration more, and producers bring more of the resource to market.
Our entrepreneur has done a truly incredible thing. She has predicted the future, and by so doing has caused every individual in the economy to prepare for a shortage they don't even know is coming! And, by discouraging consumption and encouraging production ahead of time, she blunts the impact the crisis will have. There will be more of the resource to go around when it is needed most.
On top of this, our entrepreneur still has her stockpile she saved back when everyone else was blithely using it up. She can now further mitigate the damage of the crisis by selling her stock during the worst of it, when people are most desperate for relief. She will know when this is because the price will tell her, but only if it is allowed to adjust freely. When the price is at its highest is when people need the resource the most, and those willing to pay will not waste it or hoard it. They will put it to its highest valued use.
The economy is like a big bus we are all riding in, going down a road with many twists and turns. Just as it is difficult to see into the future, it is difficult to see out the bus windows at the road ahead.
On the dashboard, we don't have a speedometer or fuel gauge. Instead we have all the prices for everything in the economy. Prices are what tell us the condition of the bus and the road. They tell us everything. Without them, we are blind.
Good times are a smooth road. Consumer prices and interest rates are low, investment returns are steady. We hit the gas and go fast. But, the road is not always straight and smooth. Sometimes there are sharp turns and rough patches. Successful entrepreneurs are the ones who can see what is coming better than everyone else. They are our navigators.
When they buy up scarce resources ahead of a crisis, they are hitting the brakes and slowing us down. When they divert resources from one area to another, they are steering us onto a smoother path. By their actions in the market, they adjust the prices on our dashboard to reflect the conditions of the road ahead, so we can prepare for, navigate and get through the inevitable difficulties we will face.
Interfering with the dashboard by imposing price floors or price caps doesn't change the conditions of the road (the number of toilet paper rolls in existence hasn't changed). All it does is distort our perception of those conditions. We think the road is still smooth--our heavy foot stomping the gas--as we crash onto a rocky dirt road at 80 miles per hour (empty shelves at the store for weeks on end).
Supply, demand and prices are laws of nature. All of this is just how things work. It isn't right or wrong in a moral sense. Price caps lead to waste, shortages and hoarding as surely as water flows downhill. The opposite--allowing prices to adjust freely--leads to conservation of scarce resources and their being put to their highest valued use. And yes, it leads to profits for the entrepreneurs who were able to correctly predict future conditions, and losses for those who weren't.
Is it fair that they should collect these profits? On the one hand, anyone could have stocked up on toilet paper, hand sanitizer and face masks at any time before the crisis, so we all had a fair chance to get the supplies cheaply. On the other hand, it just feels wrong that some should profit so much at a time when there is so much need.
Our instinct in the moment is to see the entrepreneur as a villain, greedy "price gouger". But we don't see the long chain of economic consequences the led to the situation we feel is unfair.
If it weren't for anti-price-gouging laws, the major retailers would have raised their prices long before the crisis became acute. When they saw demand outstrip supply, they would have raised prices, not by 100 fold, but gradually and long before anyone knew how serious things would have become. Late comers would have had to pay more, but at least there would be something left on the shelf.
As an entrepreneur, why take risks trying to anticipate the future if you can't reap the reward when you are right? Instead of letting instead of letting entrepreneurs--our navigators--guide us, we are punishing and vilifying them, trying to force prices to reflect a reality that simply doesn't exist.
In a crisis, more than any other time, prices must be allowed to fluctuate. To do otherwise is to blind ourselves at a time when danger and uncertainty abound. It is economic suicide.
In a crisis, there is great need, and the way to meet that need is not by pretending it's not there, by forcing prices to reflect a world where there isn't need. They way to meet the need is the same it has always been, through charity.
If the people in government want to help, the best way for the to do so is to be charitable and reduce their taxes and fees as much as possible, ideally to zero in a time of crisis. Amazon, for example, could instantly reduce the price of all crisis related necessities by 20% if they waived their fee. This would allow for more uses by more people of these scarce supplies as hoarders release their stockpiles on to the market, knowing they can get 20% more for their stock. Governments could reduce or eliminate their tax burden on high-demand, crisis-related items and all the factors that go into their production, with the same effect: a reduction in prices and expansion of supply. All of us, including the successful entrepreneurs and the wealthy for whom high prices are not a great burden, could donate to relief efforts.
These ideas are not new or untested. This is core micro economics. It has been taught for hundreds of years in universities the world over. The fact that every crisis that comes along stirs up ire against entrepreneurs indicates not that the economics is wrong, but that we have a strong visceral reaction against what we perceive to be unfairness. This is as it should be. Unfairness is wrong and the anger it stirs in us should compel us to right the wrong. Our anger itself isn't wrong, it's just misplaced.
Entrepreneurs didn't cause the prices to rise. Our reaction to a virus did that. We saw a serious threat and an uncertain future and followed our natural impulse to hoard. Because prices at major retail suppliers didn't rise, that impulse ran rampant and we cleared the shelves until there was nothing left. We ran the bus right off the road and them blamed the entrepreneurs for showing us the reality of our situation, for shaking us out of the fantasy of low prices.
All of this is not to say that entrepreneurs are high-minded public servants. They are just doing their job. Staking your money on an uncertain future is a risky business. There are big risks and big rewards. Most entrepreneurs just scrape by or lose their capital in failed ventures.
However, the ones that get it right must be allowed to keep their profits, or else no one will try and we'll all be driving blind. We need our navigators. It doesn't even matter if they know all the positive effects they are having on the rest of us and the economy as a whole. So long as they are buying low and selling high--so long as they are doing their job--they will be guiding the rest of us through the good times and the bad, down the open road and through the rough spots.

2025-05-14 05:56:15Shanghai: Bus Stops Here
A new crowd-sourced transit platform allows riders to propose, vote on, and activate new bus lines in as little as three days.
From early-morning school drop-offs to seniors booking rides to the hospital, from suburban commuters seeking a faster link to the metro to families visiting ancestral graves, Shanghai is rolling out a new kind of public bus — one that’s designed by commuters, and launched only when enough riders request it.
Branded “DZ” for dingzhi, or “customized,” the system invites residents to submit proposed routes through a city-run platform. Others with similar travel needs can opt in or vote, and if demand meets the threshold — typically 15 to 20 passengers per trip — the route goes live.
More than 220 DZ routes have already launched across all 16 city districts. Through an online platform opened May 8, users enter start and end points, preferred times, and trip frequency. If approved, routes can begin running in as little as three days.

Bitcoin Is A Joke
Joe Weisenthal Nov 6, 2013, 10:42 PM UTC
REUTERS/Eliana Aponte
Bitcoin is back in the news, as the digital currency has surged to new all-time highs in recent weeks.
A few weeks ago, it was just above $100. Today it's over $260.
This surge has prompted Timothy B Lee at The Washington Post to ask whether those who have called it a bubble in the past should retract and admit that they were wrong.
Well I'm not totally sure if I've called it a bubble, but I have spoken negatively of it, and I'll say that I still think it's a joke, and probably in a bubble.
Now first of all, I find the premise of Lee's post to be hilarious. The currency has been surging several percent every day lately, and that's evidence that it's not in a bubble?
Before going on, I want to be clear that saying something is a bubble is not saying it will go down. It could go to $500 or $1000 or $10,000. That's the nature of manias.
But make no mistake, Bitcoin is not the currency of the future. It has no intrinsic value.
Now this idea of "intrinsic value" when it comes to currency bothers people, and Bitcoin Bugs will immediately ask why the U.S. dollar has intrinsic value. There's an answer to that. The U.S. Dollar has intrinsic value because the U.S. government which sets the laws of doing business in the United States says it has intrinsic value. If you want to conduct commerce in the United States you have to pay taxes, and there's only one currency you're allowed to pay taxes in: U.S. dollars. There's no getting around this fact. Furthermore, if you want to use the banking system at all, there's no choice but to use U.S. dollars, because that's the currency of the Fed which is behind the whole thing.
On top of all these laws requiring the U.S. dollar to be used, the United States has a gigantic military that can force people around the world to use dollars (if it came to that) so yes, there's a lot of real-world value behind greenbacks.
Bitcoin? Nada. There's nothing keeping it being a thing. If people lose faith in it, it's over. Bitcoin is fiat currency in the most literal sense of the word.
But it gets worse. Bitcoin is mostly just a speculative vehicle. Yes, there are PR stunts about bars and other shops accepting bitcoins. And there is a Bitcoin ATM for some reason. But mostly Bitcoin is a speculative vehicle. And really, you'd be insane to actually conduct a sizable amount of commerce in bitcoins. That's because the price swings so wildly, that the next day, there's a good chance that one of the parties will have gotten royally screwed. Either the purchaser of the good will have ended up totally blowing a huge opportunity (by not holding longer) or the seller will be totally screwed (if Bitcoin instantly plunges). The very volatility that excited people to want to play the Bitcoin game is death when it comes to real transactions in the real world.
Again, Bitcoin might go up a lot more before it ultimately ends. That's the nature of bubbles. The dotcom bubble crashed a bunch of times on its way up. Then one day it ended. The same will happen with this.
In the meantime, have fun speculating!

2025-05-16 08:18:52Value Creation at the Edge
The conversation around artificial intelligence has largely centered on the technology itself, the capabilities of large language models, the race for more parameters, and the competition between AI companies.
He with the most data / biggest model / biggest platform wins all.
As we're been exploring in recent "Good Stuff" podcasts, the true business model of AI may be much more straightforward. AI is after all a productivity tool with little technical moat, in fact the existence of AI coding and learning tools quickly chop away at this moat even quicker!.\ \ We believe that the it's about transforming traditional human heavy businesses by dramatically reducing operational costs while maintaining or increasing output.
AI is poised to create value not primarily for AI companies themselves, but for businesses that effectively implement AI to transform their operations, particularly small, local businesses that can become extraordinarily efficient through AI adoption.
The Value Shift: From AI Companies to AI-Enabled Traditional Businesses
A central insight from episode 1 of the podcast series, is that the value of AI isn't likely to accrue primarily to companies like OpenAI or other AI technology providers. Instead, the real winners will be traditional service businesses that can leverage AI to transform their operations and cost structures.
"I think we're gonna see this shift to traditional service businesses... that traditionally have pretty fixed low margins because of a dependency on language-heavy workflows that require a lot of humans as the medium of intelligence in the business."
The opportunity here is to use AI to manage the language dependency and shift the moments of intelligence, that currently exist in the heads of our staff, into software that can run 24x7 for fractions of a cost.\ \ The real limiting factor here is less a magic AGI, but instead detailed thinking and process redesign to move humans to the edge of the process. As it turns out if we think through what each person is doing in detail we see the specific decisions, outputs, moments of intelligence are actually quite constrained and can be replicated in LLM's if we break them down to a low enough level of fidelity and take each decisions one step at a time.\ \ The result? Businesses that have traditionally operated with fixed, low margins can potentially achieve "software-style margins" by dramatically reducing their operational expenses.
Transforming Traditional Service Businesses
We have developed three key heuristics for identifying businesses that could benefit most from AI transformation:
-
Language Intensity: Businesses where much of the work involves processing language (reading, writing, communicating). Language in, language out. If you are sat in a chair and typing all day, this could be you.
-
Labor Component: Where we see this language intensity so we find many people performing similar, standardized roles. For examples, if we have four people in the same role this is a big clue we have good process, checklists, role descriptions etc for how the work can be done in order to replicate work across multiple people.
-
Load in the Business: Taking these processes into account, what amount of the operational expense of the business do they represent? Where these language and labor-intensive operations represent a significant portion of the business cost, we can see there will be significant return.
Traditional service businesses that match these criteria—legal firms, accounting practices, consulting agencies, contract engineering, design agencies and others—could see dramatic transformations through AI implementation.
By automating these language-heavy processes, businesses can potentially reduce operational costs by 50-80% while maintaining similar levels of output.
The Power of Small
We believe that small businesses may have an inherent advantage in this transformation. While large enterprises face significant barriers to reducing their workforce (political pressure, media scrutiny, organizational complexity), smaller businesses can adapt more quickly and focus on growth rather than just cost-cutting.
If I'm in a 20,000 person business and I need to remove 10,000 people... that's hard. You can't do this without sending political shock waves in your local community.
If I'm a 10 person business and I need to double my revenue, nobody gives a shit. I can just do it.
For small businesses, AI removes growth constraints. When adding the "21st person" no longer represents a significant capital investment, small businesses can scale much more efficiently:
If the next nominal client that you onboard doesn't actually cause you any more additional pain, if you don't need to hire more people to service that client... you just take off the brakes off from a growth perspective.
This gives small business a unique advantage in capitalizing on AI.
From "Bionic Humans" to "Humans at the Edge"
We currently see this integration to business happening in one of two models:
-
The Bionic Human: Equipping workers with AI tools to make them more productive.
-
Human at the Edge: Redesigning processes to be AI-native, with humans entering the process only when needed (and often facilitated by bitcoin payments).
While many businesses are focused on the first approach and it can certainly see returns, it is still a process constrained by the human input. The real value unlock comes from fundamentally redesigning business processes with AI at the core.
Now we can purchase intelligence in buckets of $0.02 API calls, how would we operate different?
This represents a profound shift in how we think about work and processes. Rather than humans being central to processes with tools supporting them, AI becomes the backbone of operations with humans providing input only at critical junctures.
This is "a complete mental shift" that challenges our fundamental assumptions about how businesses operate. The human becomes "the interface with the real world" for AI systems rather than the primary processor of information and decision-maker.
The Value Trap: Understanding the Competitive Dynamic
So what happens next? Here we have developed the concept of the Value Trap to explain how the competitive landscape will evolve as AI adoption increases..\ \
Initially, early adopters of AI and "Human at the Edge" business processes, will see dramatic benefits.
If your costs have dropped from 90 to 20 this creates an immediate competitive advantage where the early adopter is "now making 80 units of profit versus your 10 units of profit.
They gain massive pricing power in the industry and can compete for growth with an unfair advantage.
Over time, and here we believe this is likely a 5-10 year period although we believe the quicker side, competitive pressures will erode these advantages.\ \ As competitors adopt similar AI strategies, price competition will intensify, and revenues will decline. The business that initially saw its costs drop from 90 to 20 units might see its revenue decline from 100 to 30 units, resulting in similar margins but much lower overall revenue, often destroying the enterprise value of the company at these new revenue / profit levels!
This evolution creates an imperative for businesses to adopt AI early, not just to maintain perpetual advantage, but simply to survive the transition. Worse they're hit with a second challenge of the value trap, how do I keep hold of the value I generate along the way.\ \ If you're reading this on Nostr you may already suspect a way out of this value trap.\ \ If not I would invite you to consider storing the immediate short term returns you pull forwards in something that would be inflation resistant, hard to seize and ideally portable.\ \ We refer to this as a 'The big orange arbitrage".
Implications for Business Owners and Capital Allocators
For business owners, especially those running small to medium-sized enterprises, the message is clear: understand how AI could transform your industry and begin planning your transition now.\ \ This might involve creating an "AI-native twin" of your current business—similar to how Netflix developed streaming alongside its DVD business—to eventually replace your current operations. If you want help please ask, I heavily favor more small businesses in the world and would love to help make this a reality.
For capital allocation, the emerging opportunity we see if in "transformation led private equity". The acquisition of traditional service businesses and applying AI to dramatically reduce operational costs and increase enterprise value.\ \ This approach treats AI not as a product but as a transformation strategy for existing businesses with proven product-market fit.
Transformation led PE is venture style returns without the risk of product market fit.
So the lesson?
The business model of AI isn't all about selling AI technology, adding a RAG chatbot to a new DB or collecting everyone's data.\ \ Consider the humble cash flow business, use AI to transform the operational processes and save into everyone's favorite orange coin.

2025-05-17 08:31:43Absurdities from Finland
Hydrogen, Railways, and Datacenters: Just an Armchair Economist Ranting (Expect Zero Value)
"Next year we'll have growth!" they promise. Again. And again. And again.
The "economists" who yell and preach about this are just state puppets. The track record: 17-18 years of zero growth.
Finland, 1980-2025: Real GDP growth stagnant (red) while prices still bite (blue). After 2008 Red line - 17 years of “wait till next year.” — IMF DataMapper, April 2025
Why do the experts always get it wrong? Here in Finland, everybody is blinded by Keynesianism.
-
Low interest rates
-
High spending
Even those I once thought had "common sense" have become blind. They mistake subsidized sectors for "growth." So in love with the state, they ignore incentives, time preference, and basic economics.
New brave Finland - Hydrogen economy (1)
Launch event: free champagne, no customers. Taxpayers pay.
“Finland’s hydrogen economy is stuttering - there’s still no real market for it, so officials insist it must be manufactured with policy decrees and taxpayer subsidies.”
“Once science has to serve, not truth, but the interests of a state, argument exists only to vindicate the approved belief.” — The Road to Serfdom, ch. 11
Malinvestment Musical. Subsidies shuffle capital from things consumers actually want, such as lower electricity prices. Healthcare that works? I honestly don’t even know; Finnish people have become lazy and idiotic.
The Cantillon effect from this “green stimulus” showers money on consultants and lobbyists first; the average worker gets the hangover in the form of higher power bills and grocery prices.
Only companies living on subsidies call it “the future.”
(Sometimes I wish I was an engineer so I could do shit instead of just whining like a proper economist. At least then I could build something useful instead of just talking shit. Even with my limited knowledge of physics, I understand hydrogen is an inefficient way to store electricity - the laws of thermodynamics don't care about government subsidies.)
Hurray, we love the railways (2)
NATO will bring investments to Finland - Hurray!
We must rip up perfectly good tracks so we can afford to move troops we can no longer afford.
War talk has clouded judgment: when “national security” is the slogan, cost-benefit math is treason. As Hayek warned, the road to serfdom is always paved with strategic necessity.
-
What, exactly, is a "sufficient" defense for five million Finns? (Asking this here makes you a Russian Bot, though I don't like Russia or Putin.)
-
Who decides when the price tag crosses from prudent to reckless?
If hatred of an external foe sets every budget line, freedom and prosperity shrink to the margins.
In other words, the track to “strategic readiness” can be the same track to serfdom -just painted NATO blue.
When an economy flat-lines for 17 years, nothing says “revival” like swapping 1,435 mm of track for 1,520 mm - and calling it growth.
Finnish economists and "liberalists" are celebrating this? (pics in the end, can't read that X much, it has become so idiotic).
l
The Ministry of Transport has estimated that the cost of conversion work for the railway section between Haparanda and Oulu alone will exceed 1.5 billion euros. The distance is about 150 kilometers. (ESTIMATION…)
New Brave Finland – Datacenter Dissonance (3)
Well, our little minister was not involved so bad, bad, and bad!
Apparently, the box is evil if it says TikTok, but awesome if the logo reads Meta or Google. Hey, all of them are shit, just producing brain rot and stealing our data.
Low temps, reliable grid, sparse population - Finland is a logical server-farm host (shithole). But let's call it what it is: a capital-intensive, low-employment utility business. Selling it as a "high-tech jobs boom" is wishful accounting. The politicians like to yell that these investments are "Billions and Billions," yes, but how much stays in Finland? Some construction jobs and a handful of cleaners? Fucking exquisite.
"Digital Red Menace!" Lohjalainen Harri panics about Chinese bytes corrupting Finnish soil. His brilliant plan? Pray the project fails "Lohjan malliin." Nothing says "economic prosperity" like hoping jobs don't materialize! Peak Finnish paradox: pray for investments and fumble them with bureaucracy or nationalist paranoia.
What cybersecurity threat do these server farms pose to Finland? Absolutely fucking none. The data doesn't care where it sits. TikTok videos don't turn into communist spies when stored in Kouvola/Lohja. Absurd and idiotic.
Yes TikTok is brainrot and stupid shit, you have to be an idiot to install that app on your phone, but it's consumer choice - if you want it then go for it, fucking idiot. Same goes for Facebook, Instagram, all that dopamine garbage.
The Datacenter Paradox: Finland needs investment but fears investors. It celebrates clean industry then hyperventilates about who owns the servers. Classic malinvestment by decree - politicians picking winners.
Datacenters can be fine investments… BUT let's be honest about the tradeoffs. All the value goes abroad. Every megawatt sent to datacenters is not available for households or actual productive industry. Basic economics: when datacenters consume 5-10% of Finland's electricity, prices rise for everyone else. Your heating bill subsidizes Facebook's server cooling. Another brilliant example of the invisible tax of political favoritism.
The Bitcoin Alternative No One Will Discuss: Here's the real irony - datacenters can't be easily switched off during peak demand, creating grid rigidity. Bitcoin mining farms, meanwhile, could be turned on/off based on grid needs, serving as perfect complementary loads for Finland's growing but inconsistent renewable energy (wind/solar). Miners would pay premium rates during excess generation and shut down during shortages - a genuine market solution! But no, can't have sound money solutions in Finland. Better to have Googles servers running 24/7 regardless of grid conditions than allow the evil Bitcoin to improve our renewable energy economics. God forbid we actually use a solution that simultaneously strengthens the grid, supports renewables, AND promotes sound money. That might accidentally lead to common sense, and we can't have that in Finland.
General Observations: The Finnish Decay
Finland is slowly becoming like southern Europe, where nothing gets done on time. We used to laugh at how inefficient and idiotic it is there, but it is now the same here. I got a reply from my Bank after 4-5 months of sending a message. Asking for offers? Wait 3-4 months in some cases (I had this with garbage service). Need a solid service man? Let's see if somebody is free in 2 weeks? Well, I am also becoming like this with my business; nobody even cares.
Rotting services and entertainment
Hard to imagine our restaurant industry was almost on par with Sweden and Denmark just +5 years ago. Today? How many good restaurants have quit? How many Michelin stars have we lost?
Well, how about concerts? Our biggest stadium this summer will host Iron Maiden in June and Robbie Williams in September. WTF? Even the Baltic states can attract bigger names than Finland, this is becoming total shithole in every aspect.
Why?
COVID, collapsing purchasing power, bureaucracy cancer, tax asphyxiation, war hysteria, sheepish compliance, and state dependency.
The entrepreneurial drive that once built world-leading companies has withered. Why innovate when bureaucrats decide winners? Why take risks when failure is punished extremely hard (lifelong debt prison, and shame) and success is taxed away?
The result: economic stagnation rationalized as "social stability" and "equality."
Economic literacy has collapsed. Even the economists here don't grasp the basic concepts, so how on earth could the average citizen? The scariest part is that they don't even care. They've outsourced their economic thinking to the state, the same way they've outsourced their responsibility and risk management. The blind leading the blind, straight to economic mediocrity.
The Finnish Decay: When Will We Say "Enough"?
It would be a good idea to write a book in a similar style to Lawrence Lepard's Big Print: What Happened To America And How Sound Money Will Fix It.
Make readers mad! Advocate for hard money and small government.
Problems? and What's next? Recession 1990s → Nokia Mirage → Euro‑Zone Handcuffs → GFC & The Silent Depression → Everyday Decay → Complete state dependency or get mad?
A glimmer of hope: Despite the lost decades, there's a spark in Finland's youth. They hustle and show more entrepreneurial spirit, saving habits, and investment interest than their parents.
In 1999, we were a top country in education, technology, healthcare, and debt contracted on top of that we were one of the safest places to live, we didn’t lock the bikes and even the doors…
Now look at us?
When will Finns wake up and say enough?
As Hayek warned: "A movement whose main promise is the relief from responsibility cannot but be antimoral in its effect, however lofty the ideals." We've outsourced our moral obligations to an impersonal state, weakening "both the willingness to bear responsibility and the consciousness that it is our own individual duty."
We need a hard money and personal responsibility renaissance.
Coming soon: "How Sound Money and Small Government Can Save Finland From Its Slow-Motion Suicide"
News and sources:
I recently finished reading F.A. Hayek's "The Road to Serfdom" (1944). The similarities between Hayek's warnings and Finland's current course are striking. Europe and Finland are ramping up defence spending to ridiculous levels, now even talking over 5% GDP levels, which is total insanity. What would be enough for defence? We have little freedoms left here in Finland (and Europe), and in pursuit of “security,” we might lose it all. Central planners who believe they can direct an economy better than market forces are just clowns, from hydrogen to datacenter politics. What market forces have we left in Finland? I can breath freely? Soon that will be taxed too. Next we have CBDC coming up in EU.
I highly recommend reading "The Road to Serfdom." Its analysis of how good intentions lead to economic ruin remains as relevant in 2025 as it was in 1944. I feel like a total idiot for not reading it before.
Read 27 books so far this year, thx for Jack Dorsey “reading challenge” I started this in March, aim was 50 book but now we aim to 100, so fucking good to read books!
