## Renoters: Proposal for Anonymous Event Relaying in Nostr
*This document is a proposal and not an official NIP.*
This Document proposes "Renoters," a mechanism for anonymous event relaying in Nostr, inspired by the Mixminion remailer design. Renoters aim to enhance privacy by obscuring the origin of events, making it difficult to trace the author of a message.
### **Motivation**
While Nostr offers a decentralized platform, current relay mechanisms can potentially reveal the source of events. Renoters address this by introducing an onion-routing-like system where events are encrypted and relayed through a series of nodes, making it harder to link the event to its originator. This enhances privacy for users who wish to communicate anonymously or protect their identity.
In some totalitarian regimes, the use of Tor and VPNs is criminalized, making online anonymity dangerous. Even in some democratic countries, merely downloading Tor can mark individuals as suspects. This underscores the need for a decentralized and anonymous communication system that operates independently of commonly surveilled privacy tools.
### **Proposed Solution**
Renoters operate on the principle of "gift-wrapping" events, using asymmetric encryption. A user wishing to send an event anonymously performs the following steps:
1. **Event Creation:** The user creates the Nostr event they wish to publish.
2. **Renoter Path Selection:** The user selects a path of Renoters through which the event will be relayed. This path can be pre-configured or dynamically chosen.
3. **Gift Wrapping (Encryption and Signing):** The user encrypts and signs the event for each Renoter in the path, working in reverse order:
- A *new* random Nostr private key (`sk_wrapper`) is generated.
- The event (or the previously wrapped event) is encrypted using the *next* Renoter's Npub (`npub_next`) using Nostr's standard encryption mechanism (e.g., using shared secrets derived from the private key and the recipient's public key).
- A *new* Nostr event is created. This "wrapper" event's content contains the ciphertext. The wrapper event is signed using the newly generated private key `sk_wrapper`. The wrapper event also includes the next hop's `npub_next` (or the final destination if it's the last renoter) in cleartext, to allow for routing.
4. **Publication:** The user publishes the *first* gift-wrapped event (the one encrypted for the last Renoter in the path). This event is sent to a regular Nostr relay, which then forwards it to the first Renoter in the path.
5. **Renoter Relaying:** Each Renoter in the path receives the gift-wrapped event, verifies the signature using the `sk_wrapper`'s corresponding public key, decrypts it using its own private key, and forwards the decrypted event (now wrapped for the *next* Renoter) to the next Renoter in the path. This process continues until the event reaches the final Renoter.
6. **Final Delivery:** The final Renoter decrypts the event and publishes it to the Nostr network.
### **Example**
Let's say Alice wants to send an event anonymously through Renoters R1, R2, and R3.
1. Alice creates her event.
2. She generates a random private key `sk3` and encrypts the event with R3's public key `npub_r3`.
3. She creates a wrapper event containing the ciphertext and `npub_r3`, signed with `sk3`.
4. She generates a random private key `sk2` and encrypts the previous wrapper event with R2's public key `npub_r2`.
5. She creates a wrapper event containing this ciphertext and `npub_r2`, signed with `sk2`.
6. She generates a random private key `sk1` and encrypts the previous wrapper event with R1's public key `npub_r1`.
7. She creates a final wrapper event containing this ciphertext and `npub_r1`, signed with `sk1`.
8. Alice publishes this final wrapper event.
R1 decrypts with its private key, verifies the signature with the public key corresponding to `sk1`, and forwards to R2. R2 decrypts, verifies the signature with the public key corresponding to `sk2`, and forwards to R3. R3 decrypts, verifies the signature with the public key corresponding to `sk3`, and publishes the original event.
### **Renoter Incentives (using Cashu)**
To incentivize Renoters to participate in the network, this NIP proposes integrating Cashu tokens as a payment mechanism.
- **Token Inclusion:** When a user creates the initial gift-wrapped event (the one sent to the first Renoter), they include a Cashu token *within* the event content. This token is itself encrypted and wrapped along with the original message, so only the receiving Renoter can access it.
- **Renoter Redemption:** Upon receiving a gift-wrapped event, the Renoter decrypts it. If the event contains a Cashu token, the Renoter can decrypt the token and redeem it.
- **Renoter Behavior:** Paid Renoters would be configured *not* to relay events that do *not* contain a valid Cashu token. This ensures that Renoters are compensated for their service. Free Renoters could still exist, but paid Renoters would likely offer faster or more reliable service.
- **Token Value and Tiers:** Different Cashu token denominations could represent different levels of service (e.g., faster relaying, higher priority). This could create a tiered system where users can pay for better anonymity or speed.
- **Token Generation:** Users would need a way to acquire Cashu tokens. This could involve purchasing them from a Cashu mint or earning them through other means.
### **Security Threats and Mitigations**
- **Anonymity Against Correlation Attacks:** Even when using Tor, traffic patterns can still be analyzed to infer the origin of events. To mitigate this risk, Renoters can introduce:
- Random delays in event relaying.
- Dummy packets to complicate statistical analysis by malicious observers.
- **Replay Attacks:** To mitigate replay attacks, each Renoter must store, for a reasonable period, the IDs of received events and the decrypted events that were forwarded. This ensures that duplicate messages are not processed again.
- **Sybil Attacks:** Sybil attacks can be mitigated by requiring payments via Cashu tokens for relaying events, increasing the cost of launching such attacks. By ensuring that each relay operation has a monetary cost, attackers are discouraged from creating large numbers of fake identities to manipulate the network.
- **Traffic Analysis:** Traffic analysis can be mitigated by using Tor for Renoters. Routing events through the Tor network adds an additional layer of anonymity, making it more difficult to track message origins or infer sender-recipient relationships. While Renoters enhance privacy, sophisticated traffic analysis might still be a threat.
### **Operational Considerations**
- **Renoter Reliability:** The reliability of the Renoter network is crucial.
- **Latency:** Relaying through multiple Renoters will introduce latency.
- **Key Management:** While each layer uses a new key, the initial key generation and path selection process need to be secure.
This NIP provides a robust framework for anonymous event relaying in Nostr, leveraging encryption and Cashu-based incentives to enhance privacy and usability.

A liberdade de expressão e a descentralização do poder estão intimamente ligadas ao avanço do pensamento humano e à construção de uma sociedade mais justa e consciente. A evolução da compreensão sobre o certo e o errado surge da comunicação, da observação empírica e da análise das consequências de ações passadas.
Para que haja uma aproximação real com a verdade e uma relação equilibrada entre a razão da vida e o convívio com o poder, é essencial garantir a liberdade de expressão. Somente por meio do livre debate de ideias é possível avaliar as diversas perspectivas, identificar erros e aprender com eles.
Embora a maioria das pessoas busque o aprendizado e a compreensão do que é correto, o apego cego a uma ideia evidentemente equivocada pode fazer com que percam o real propósito da busca pela verdade. Em vez de refletirem criticamente, muitos acabam apenas defendendo um erro pelo simples fato de se identificarem com ele.
Esse é um dos motivos pelos quais a censura tem se tornado uma ferramenta tão temida e contestada. Ilude-se quem acredita que a censura existe apenas para combater crimes e golpes. Na realidade, quanto maior a censura, mais favorecidos são aqueles que desejam ocultar informações, tornando ainda mais difícil a identificação e o combate a abusos.
Nos países livres, onde a liberdade de expressão é respeitada, há maior autonomia nas decisões políticas e um engajamento mais ativo da população. A participação cidadã fortalece o controle do povo sobre as influências que moldam o convívio social, garantindo que o poder não fique concentrado nas mãos de poucos, mas distribuído de forma mais democrática e justa.

\
Rückblickend sieht das Jahr 2022 wie eine Art Höhepunkt aus. Während der Großteil der Gesellschaft weitgehend vergessen hat, was die politische Klasse ihren Untertanen während der sogenannten Pandemie angetan hat, kotzte Hollywood weiterhin Inhalte aus, die von „diversen" Regisseuren und Drehbuchautoren produziert wurden und bis zum Rand mit nicht ganz so subtilen Botschaften und Verachtung für ihr Publikum gefüllt waren.
Star Wars und Marvel haben nach der Übernahme durch Disney auf diese Weise Franchise-Mord begangen, und auch das Erbe von *Der Herr der Ringe* wurde von der linken Idiotie vergewaltigt und für immer befleckt. Jetzt gibt es von jedem männlichen Avenger eine weibliche Version. Hugh Jackman, der Schauspieler, der früher die Hauptrolle des X-Men-Mutanten Wolverine spielte, empfahl seinen Anhängern in den sozialen Medien kürzlich Bill Gates' Buch über den Klimawandel.
Als Frauen verkleidete Männer gewinnen Sportmeisterschaften für Frauen, und alle haben so viel Angst davor, als bigott bezeichnet zu werden, dass sich niemand traut, auf die Absurdität hinzuweisen, dass ein Mann alle Mädchen schlägt. Diese so genannten Sportler werden als „mutig" bezeichnet, obwohl sie alles andere als das sind.
Die Tatsache, dass es in einigen Berufen mehr Männer als Frauen gibt, wird als Problem angesehen, aber warum genau das ein Problem ist, wird selten erwähnt. Die Verdienste und die tatsächliche Meinungsvielfalt werden auf dem Altar der „Vielfalt und Integration" geschlachtet.
Die Gesellschaft ist an einem Punkt angelangt, an dem die Verbraucher Ärzten und Anwälten gerade wegen ihrer Hautfarbe misstrauen, da sie vermuten, dass sie deshalb in ihre Positionen gekommen sind und nicht wegen ihrer Kompetenz oder ihrer Verdienste. Noch vor zwanzig Jahren war die normale Bauchreaktion das Gegenteil: „*Wow, ein Arzt aus einer Minderheit! Sie müssen hart gearbeitet haben, um dorthin zu gelangen, wo sie heute sind!*"
Als ich aufgewachsen bin, wurde ein „Rassist" als jemand definiert, der sich einen Dreck um die Hautfarbe oder die ethnische Zugehörigkeit einer anderen Person scherte. Dasselbe galt für das Wort „Sexist" - man war ein Sexist, wenn man das Geschlecht einer Person bei der Beurteilung berücksichtigte.
Ich hatte das Gefühl, dass die Welt seit den Gräueltaten des Zweiten Weltkriegs im Kampf gegen diese Vorurteile einen weiten Weg zurückgelegt hatte und dass jeder eine anständige Karriere in jedem Beruf machen konnte, wenn er sich nur anstrengte und sich Mühe gab. Doch irgendwann in den frühen 2000er Jahren änderte sich etwas.
Plötzlich begannen die Worte das Gegenteil von dem zu bedeuten, was sie ursprünglich bedeuteten. Plötzlich war jeder, der sich einen Dreck um seine Hautfarbe scherte, ein Rassist. Jeder, dem es egal war, ob der CEO eines großen Unternehmens ein Mann oder eine Frau war, war ein Sexist.
Im Jahr 2023 behaupten manche sogar, man sei ein „Transphobe", wenn man nicht gelegentlich Fellatio an einem „weiblichen Penis" betreiben will. Die Tugendwächter laufen in der Tat Amok, und die Medienunternehmen lieben es. Sie lieben es, weil sie alles lieben, was die Kluft zwischen den Menschen schürt. Je verrückter die Aktionen der Clownwelt® sind, desto wütender sind die Reaktionen der leichtgläubigen, verärgerten Menschen auf der „vernünftigen" Seite des politischen Spektrums.
Die Menschheit neigt dazu, sich wie ein Pendel oder eine Abrissbirne zu verhalten, wenn es um politische Meinungen oder „die aktuelle Sache" geht.
Wenn es zu viele blauhaarige, übergewichtige, lesbische, glutenintolerante, vegane Umweltschützer gibt, taucht von irgendwoher eine Welle von Skinheads auf, die mit Steroiden vollgepumpt sind und gegen Samenöl und Fleischfresser sind.
Für jede Hillary Clinton gibt es einen Donald Trump. Für jede Greta Thunberg gibt es einen Andrew Tate. Für jeden CNN-Reporter gibt es einen Alex Jones.
Auch im Bitcoin-Bereich gibt es immer ein „aktuelles Thema", an das man sich klammern kann, wenn auch oft eine männlichere Idee als das „aktuelle Thema" des Mainstreams. Was nur wenige wissen, ist, wie faul diese Art des Denkens ist.
Wissenschaft ist nicht automatisch schlecht, nur weil „die Wissenschaft" schlecht ist.
Nur weil man gelernt hat, dass alles, was die Regierung sagt, eine Lüge ist, ist nicht automatisch auch das Gegenteil wahr. Die Welt ist nuanciert; die meisten Dinge sind nicht schwarz oder weiß.
Was wahr und sehr schwarz-weiß ist, ist das Geld - es gibt Bitcoin und es gibt Shitcoins. Nur wenn wir letztere für erstere aufgeben, können wir die Politik aus dem menschlichen Handeln entfernen und uns auf eine gewisse Wahrheit in der Basisschicht der Zivilisation zurück arbeiten. Bitcoin belohnt weder Rent-Seeking noch faules Denken.
Die positiven Aspekte vieler moderner Technologien werden oft übersehen. Auch wenn sich die Clownwelt® und die lächerlichen Ideen, die ihr folgen, wie ein Lauffeuer verbreiten, gibt es Gründe für einen ungetrübten Optimismus für die Zukunft.
Wir hören oft von den Gefahren der sozialen Medien und wie sie die Gehirne unserer Kinder schädigen, aber wir werden selten an die Kehrseite der Medaille erinnert. Soziale Medien verbinden Menschen in einem Ausmaß, das der Menschheit nie zuvor zugänglich war. Jeder Mensch auf der Welt kann heute mit jedem anderen in Kontakt treten und mit einem Mausklick einen Videoanruf starten. Das ist ein enorm wichtiges Instrument für den Frieden. In Kombination mit Bitcoin haben die Bösewichte keine Chance mehr.
Wenn jeder auf diese Weise vernetzt ist, wird überdeutlich, wie absurd es ist, dass wir in Staaten mit unterschiedlichen Gesetzen und Vorschriften leben. Warum gelten für meine Mitmenschen auf der anderen Seite dieses Teiches, dieses Flusses, dieses Gebirges oder sogar dieser imaginären Linie in der Erde andere Regeln?
Jeden Tag wachen mehr und mehr Menschen auf und erkennen, dass es nur ein einziges Menschenrecht gibt - das Recht, in Ruhe gelassen zu werden.
Immer mehr Menschen erkennen, dass die Geldentwertung kein natürliches Phänomen ist, sondern eine bewusste Politik. Es ist nur eine Frage der Zeit, bis die alte Welt verschwindet. Solange wir kommunizieren dürfen, gibt es Hoffnung. Das Internet hat bewiesen, dass sich jede Kommunikation auf eine Reihe von Einsen und Nullen reduzieren lässt, und Bitcoin hat bewiesen, dass Geld nichts anderes als Information ist.

# NOSTR SDK FOR APPLE PLATFORMS
## Progress Report # 2: Nov 2024 - Jan 2025
[Nostr SDK for Apple Platforms](https://github.com/nostr-sdk/nostr-sdk-ios) continued to make progress this quarter. I am still the sole part-time active developer and maintainer of Nostr SDK for Apple Platforms.
Implementations for a few NIPs were added or updated. The CI build pipeline was broken due to deprecated dependencies, which have since been fixed.
I pushed out a (controversial) [proposal](https://github.com/nostr-protocol/nips/pull/1770) to gracefully deprecate stringified JSON in favor of tags on user metadata kind 0 events to the NIPs repo as a pull request to improve consistency and reduce the complexity of reading and writing this commonly used kind. The SDK has become the first to [implement](https://github.com/nostr-sdk/nostr-sdk-ios/pull/212) with the hopes that others will follow.
We have had new external interest in the SDK from developers working on various Nostr clients:
- Damus has [copied the NIP-44 encryption implementation from the SDK](https://github.com/damus-io/damus/pull/2850/files#diff-5eb31bd8e6dc73d21bb3caef975a7f3508765e7f3ab01ecec545635ccb89d17c) for their use in [NIP-37 Draft Events](https://github.com/nostr-protocol/nips/blob/7cc120ecb01963e37f9adcd3b57b8efc1dd9e828/37.md), swapping out their previous usage of rust-nostr due to large binary size issues.
- [Fabian](nostr:npub1n0sturny6w9zn2wwexju3m6asu7zh7jnv2jt2kx6tlmfhs7thq0qnflahe) from Nostur contributed a [NIP-44 encrypt/decrypt example](https://github.com/nostr-sdk/nostr-sdk-ios/pull/204) to the SDK demo project to help him understand how it works and is [currently being used](https://github.com/nostur-com/nostr-essentials/blob/05e5452bb05c4c2e94ec9a78bb0c80d5123919a7/Sources/NostrEssentials/NIP-44/NIP44v2Encrypting.swift) by Nostur
- A new livestreaming Nostr client called [Swae](https://github.com/suhailsaqan/swae) has adopted the SDK, using Comingle as a reference client implementation.
Progress on the SDK this quarter has been slower than the previous quarter due to a shift in emerging priorities in Nostr. This quarter, I focused on building a native iOS Nostr event signer, as none exist today. The problem is that some iOS users do not fully trust pasting their private key into Nostr clients, which they fear could be buggy or malicious in accessing and signing bad data with their private key. A native signer on Android called Amber already exists, and there has been an increase in demand from users for an equivalent solution on iOS. The iOS signer app is called [Yeti](https://github.com/tyiu/Yeti) (credit to [Karnage](nostr:npub1r0rs5q2gk0e3dk3nlc7gnu378ec6cnlenqp8a3cjhyzu6f8k5sgs4sq9ac) for the name and Figma designs) and I'm using Nostr SDK for Apple Platforms and its demo app as a [test bed](https://github.com/nostr-sdk/nostr-sdk-ios/tree/tyiu/signer-demo) for this experimental cross-app communication protocol that will eventually be proposed as a NIP. I hope iOS clients adopting the SDK will get built-in standardized event signing protocol capabilities, tightening up this attack vector.
This report marks the end of the six-month grant period, as agreed with OpenSats. I thank OpenSats for supporting Nostr SDK for Apple Platforms, other Nostr projects, and the developer community. I will re-apply for a grant at OpenSats for the SDK, Yeti, or other impactful Nostr projects.
## 1) How did you spend your time?
Below is a broken-down summarized bulletpointed list of completed tasks.
### Development of Nostr SDK for Apple Platforms
#### Added
- [NIP-37 Draft Events](https://github.com/nostr-protocol/nips/blob/master/37.md)
- [NIP-44 encrypt/decrypt example to demo project](https://github.com/nostr-sdk/nostr-sdk-ios/pull/204)
### Updated
- [Updated NIP-11 Relay Information Document implementation](https://github.com/nostr-sdk/nostr-sdk-ios/pull/201) to support all the newly added fields
- [Renamed ParameterizedReplaceableEvent to AddressableEvent and NonParameterizedReplaceableEvent to NormalReplaceableEvent](https://github.com/nostr-sdk/nostr-sdk-ios/pull/205) to conform to the [new terminology](https://github.com/nostr-protocol/nips/pull/1418) in the NIPs repo
- Gracefully deprecated stringified JSON in favor of tags on user metadata kind 0 events, being the first to implement the [not-yet-merged proposal](https://github.com/nostr-protocol/nips/pull/1770) to NIP-01/NIP-24
### Fixed
- Fixed broken CI build pipeline
- [Fix GitHub workflow for running build and test](https://github.com/nostr-sdk/nostr-sdk-ios/pull/202)
- [Upgrade upload-pages-artifact from deprecated version to v3 to fix build](https://github.com/nostr-sdk/nostr-sdk-ios/pull/207)
- [Upgrade deploy pages action to v4 to fix build](https://github.com/nostr-sdk/nostr-sdk-ios/pull/208)
#### In Progress
- Native iOS event signing protocol, using the [SDK as a test bed](https://github.com/nostr-sdk/nostr-sdk-ios/tree/tyiu/signer-demo)
## 2) What do you plan to work on next quarter?
The top priorities will be developing the native iOS event signing protocol, building out Yeti, and integrating the iOS signing protocol into the SDK.
I will continue maintaining and developing the SDK, albeit at a slower pace:
- Deprecate EventCreating protocol in favor of NostrEventBuilding protocol for the remaining event kinds
- Add or update implementations for various NIPs where critical or needed
- Support clients as they integrate with parts of the SDK by answering questions, fixing any issues they have, adding requested features, and reviewing pull requests
## 3) How did you make use of the money?
Living expenses.

I recently wrote a post “[What? Do Not Pray For ...](https://trustjesus.substack.com/p/what-do-not-pray-for)” where I shared a passage telling us not to pray for the nation of Israel (at a particular point in time). Before reading this post, I strongly encourage you to read that post first.
The verse in question was:
> “As for you, **do not pray for this people, and do not lift up cry or prayer for them, and do not intercede with Me; for I do not hear you**. Do you not see what they are doing in the cities of Judah and in the streets of Jerusalem? The children gather wood, and the fathers kindle the fire, and the women knead dough to make cakes for the queen of heaven; and *they* pour out drink offerings to other gods in order to spite Me. Do they spite Me?” declares the Lord. “Is it not themselves *they spite,* to their own shame?” (Jeremiah 7:16-19) {emphasis mine}
Jeremiah was told not to pray blessings on Israel because Israel had turned away from God and were serving other Gods.
I was just listening to a “Renewing Your Mind” podcast and the speaker made the statement, “We all want to say, ‘God bless America,’ but we don’t want to hear, ‘God curse America.’” That made me contemplate, “Should we ask God to bless America?”
Over the past decade or more (probably several decades), America has been using its military and economic might to push actions around the globe that are abhorrent to God. We give aid to countries if they legalize and fund abortions, if they promote gay marriage, and if they encourage transgender surgeries and chemical castration. They encourage people and nations to murder unborn children, to redefine marriage as different than what God created it to be, and to sterilize young people confused about their gender, breaking both God’s good creation of male and female and \
His command to be fruitful and multiply. You could make the argument that the US has been the largest purveyor of evil in the world. (It breaks my heart to say this.)
It is true that with the past election, America has turned away from many of these evil actions, but have Americans truly repented and turned back to God? I am convinced that neither our leaders nor most of our people have turned back to God in any significant way. It is like famous atheist, Richard Dawkins, saying he misses Christian culture but continuing to reject God and make fun of actual Christians. We can’t have it both ways. We can’t have God’s blessings without God.
Now I am not saying that we shouldn’t pray for America. It is totally appropriate to pray for revival in America. It is good to pray for Americans to repent of their sins and to trust in Jesus. It is great to pray for God to help us to share the gospel and to produce fruit. The issue is that we shouldn’t pray for America’s blessing while she has turned her back on God.
Obviously there are a decent number of Christians in America. That and the fact that America was founded on Christian principles actually means that America will be punished harsher than those nations where people have had little knowledge of the Bible and Jesus. Those who have been shown the gospel and still rejected God will be held to a higher standard and will be punished harsher than those who have never heard the gospel.
I ask you to pray that God would bring revival to America, that He would turn hearts and minds to Himself, and that He would draw our leaders to submit in full trust and obedience to Him. I also pray that God would help all of believers to be faithful stewards with all of the blessings with which He has already showered us and to use us to shine the light of the gospel with America and the rest of the world. I pray that He would help us to live lives fully devoted to Him and will help us to stand out from the crowd of pseudo-Christians and normal people, so we can be used to draw America back to God.
Unfortunately, we may be in a situation, like Jeremiah and Israel, where the nation has turned so far from God that we will be rejected in the same way they reject Jesus. We may have to look upon the nation we love and let go because our citizenship is in heaven. We need to always be more devoted to God and His kingdom than we are to our earthly citizenship.
> “Son of man, if a country sins against Me by committing unfaithfulness, and I stretch out My hand against it, destroy its supply of bread, send famine against it and cut off from it both man and beast, even though these three men, Noah, Daniel and Job were in its midst, by their own righteousness they could only deliver themselves,” declares the Lord God. (Ezekiel 14:13-14)
May God guide you in your prayers, your actions, and your faith so that you will be a light in the darkness and never forget where your allegiance lies. I pledge allegiance to my God, my Lord, and my Creator, and to Him alone does my allegiance belong.
Trust Jesus

*„Privatsphäre ist für eine offene Gesellschaft im elektronischen Zeitalter notwendig. Privatsphäre ist keine Geheimhaltung. Eine private Angelegenheit ist etwas, von dem man nicht möchte, dass es die ganze Welt erfährt, aber eine geheime Angelegenheit ist etwas, von dem man nicht möchte, dass es irgendjemand erfährt." Privatsphäre ist die Macht, sich der Welt selektiv zu offenbaren.“* **- Eric Hughes, [A Cypherpunk's Manifesto](https://www.activism.net/cypherpunk/manifesto.html?ref=discreetlog.com) , 1993**
**Privatsphäre ist für die Freiheit unerlässlich.** Ohne Privatsphäre ist der Einzelne nicht in der Lage, frei von Überwachung und Kontrolle Entscheidungen zu treffen. Mangelnde Privatsphäre führt zum Verlust der Selbstbestimmung. Wenn Einzelpersonen ständig überwacht werden, schränkt dies unsere Fähigkeit ein, uns auszudrücken und Risiken einzugehen. Alle Entscheidungen, die wir treffen, können negative Auswirkungen auf diejenigen haben, die uns überwachen. Ohne die Freiheit, Entscheidungen zu treffen, kann der Einzelne nicht wirklich frei sein.
**Freiheit ist für den Erwerb und Erhalt von Wohlstand von entscheidender Bedeutung.** Wenn der Einzelne nicht die Freiheit hat, Entscheidungen zu treffen, hindern uns Einschränkungen und Beschränkungen daran, wirtschaftliche Chancen zu nutzen. Wenn es uns in einem solchen Umfeld irgendwie gelingt, Wohlstand zu erlangen, kann mangelnde Freiheit zur direkten Beschlagnahme von Vermögenswerten durch Regierungen oder andere böswillige Organisationen führen. Wenn die Freiheit gefährdet wird, führt dies im großen Maßstab zu weitverbreiteter wirtschaftlicher Stagnation und Armut. Der Schutz der Freiheit ist für den wirtschaftlichen Wohlstand von wesentlicher Bedeutung.
Der Zusammenhang zwischen **Privatsphäre, Freiheit und Wohlstand** ist entscheidend. Ohne Privatsphäre verliert der Einzelne die Freiheit, frei von Überwachung und Kontrolle Entscheidungen zu treffen. Während der Mangel an Freiheit den Einzelnen daran hindert, wirtschaftliche Chancen wahrzunehmen, und den Vermögenserhalt nahezu unmöglich macht. ***Keine Privatsphäre? Keine Freiheit. Keine Freiheit? Kein Wohlstand.***
Rechte werden nicht gewährt. Sie werden eingenommen und verteidigt. Rechte werden oft als Erlaubnis der Machthaber missverstanden, etwas zu tun. Wenn dir jedoch jemand etwas geben kann, kann er es dir grundsätzlich nach Belieben wegnehmen. Im Laufe der Geschichte haben Menschen zwangsläufig für Grundrechte gekämpft, darunter Privatsphäre und Freiheit. Diese Rechte wurden nicht von den Machthabern gegeben, sondern durch Kampf eingefordert und erkämpft. Selbst nachdem diese Rechte erlangt wurden, müssen sie kontinuierlich verteidigt werden, um sicherzustellen, dass sie nicht weggenommen werden. **Rechte werden nicht gewährt – sie werden durch Kampf erworben und durch Opfer verteidigt.**

Europe's economic framework requires restructuring grounded in realism. The Commission's Competitiveness Compass, alas, reveals dangerous left-hemisphere dominance and risks repeating Mao's mistakes.
The European Commission presented its "competitiveness compass" in January. There will be massive investments in biotechnology, materials technology, medicines, space, and the defence industry. AI gigafactories are to be established, while Europe will "maintain its leadership in quantum technologies" (a leadership that few seem to be aware of). This will be achieved through more environmental labelling schemes, nature credits, procurement rules, platforms, cooperation plans, and coordination systems. Although the report contains some bright spots, such as promises to ease the regulatory burden, **the overall picture is strikingly lacking in creativity**. Instead, we are mainly met with the usual thought patterns of the European technocracy, which manifest in additional centralised frameworks, quantifiable goals, and annual reports. Mao's ghost haunts Brussels.
#### The Missing Half of Europe's Brain
Iain McGilchrist, a British psychiatrist and philosopher, has launched the hemispheric hypothesis (a theory about how the two hemispheres of the brain work). The left hemisphere is more detail- and control-oriented, while the right hemisphere is holistic and creative. A society dominated by the left hemisphere, [like our own according to McGilchrist](https://www.youtube.com/watch?v=WYB7P-xPRsk), "would see it as its task to control everything maximally." **The Commission's compass appears similarly lobotomised , prioritising measurable processes over imaginative solutions.**
In an earlier text, I mentioned that Europe might need to return [to its roots](https://www.affarsvarlden.se/kronika/enlund-lar-av-elon-musk-vi-behover-ett-mer-radikalt-europa) and asked if Europe should have "the same end goal as China." This is still a relevant and justified question. But if we are honest, China has implemented a series of well-thought-out reforms since the 1980s, in addition to its many well-known and large-scale investments. It is not necessarily wrong to be inspired by China, as many believe; it depends on which China you are inspired by.
#### Lessons from the Cat Theory
When Deng Xiaoping returned to power in the late 1970s, he chose a more pragmatic approach than his predecessors. China left Mao Zedong's purges of dissidents behind. Instead, he launched the cat theory: **"it doesn't matter what colour the cat is as long as it catches mice"**, regarding economic development. It was now free to experiment with different models. Instead of ideological conformity, the most important thing was to increase productivity and material prosperity.
What was done in China?
* Companies and individuals were given more freedom
* Provinces and municipalities were given more autonomy
* Special economic zones were established, with different conditions and rules
* Programs to increase the number of banks were introduced
* The banking sector was deregulated
* Property rights and contract law began to be respected
China has since gone from being an economic backwater to not only being the world's largest economy in terms of purchasing power but also a [global tech contender](https://www.aspi.org.au/index.php/report/critical-technology-tracker) (leading in 37 out of 44 key technologies per ASPI).
#### EU's Compliance Obsession vs Chinese Pragmatism
And today, when China is astonishing the world with surprisingly cheap and competent AI systems, which recently set American tech stocks in motion, in the EU one is met with advertisements for yet another compliance training, this time about AI. **Every new compliance training echoes Mao's ghost** – ideological correctness overriding practical results. Is prosperity really built with certifications, directives, requirements, and penalties?
When we compare the Chinese experience with today's EU, the contrast is clear:
* Freedoms are curtailed. The right to privacy is undermined (Chat Control, etc.)
* Member states' ability to self-govern is reduced, year by year
* Streamlining and harmony are popular buzzwords in the bureaucracy
* The ECB is actively working to reduce the number of banks
* The banking sector is being regulated more and more
* Property rights and contract law are being eroded, which can be partly attributed to [developments in payment systems](https://underorion.se/en/posts/freedom_to_transact/)
Deng's cat theory was an example of when the right hemisphere was involved in decision-making. Rather than just focusing on details (the cat's colour), the whole (the result) was important. **The Chinese proverb "cross the river by feeling the stones" is another example of more holistic thinking**. Under Deng's leadership, reforms were first tested in a free zone or a province. After a while, the reforms could be evaluated before they were possibly implemented on a larger scale. "Try before you buy" is also a wise principle that follows from complexity research. In sharp contrast to this approach was Mao's "Great Leap Forward," a part of a disastrous five-year plan that shows what can happen when the left hemisphere is given too much power. A tragedy of historic proportions - a mass famine - resulted. While Deng exorcized Mao's ghost through pragmatic experimentation, Brussels seems determined to resurrect. **Today's EU risks repeating Mao's mistake of letting political abstractions ("green transition! digital decade!") override reality** – Mao's ghost surely smiles at nature credit schemes replacing actual market signals.
#### Mao's ghost trives on the ontological mistake
The serious problems that the EU is facing have been built up over decades and stem from incorrect assumptions. The economy is not complicated. It is complex. The concepts are often confused, but they describe two fundamentally different things. The complicated refers to something composite, but which can still be unfolded and then folded back up again without changing its essence. The complex, on the other hand, refers to something entangled, where every attempt to divide it changes its character. Compare, for example, an airplane engine with a béarnaise sauce. If you mix up the concepts, you make an ontological mistake, a philosopher would say. A programmer would say: garbage in, garbage out. **Mao's ghost thrives on this ontological error**, convincing technocrats they can blueprint society like a Soviet tractor factory.
**When a system is complicated, predictable, and linear, centralised coordination and control by the left hemisphere can work well.** But in complex systems, it can never be a solution because it leads to reduced adaptability and increased system risks. Instead, the goal should be diversity and decentralisation, which provide greater adaptability! The faster the changes of the system or in the environment, the greater the demands on adaptability and flexibility - if the system is to survive, that is. Increased diversity and decentralisation would not only increase adaptability and flexibility but also promote creativity, an ability that will likely become increasingly important in a world where AI and automation are changing the rules.
#### A better path forward
Europe's economic framework requires restructuring grounded in realism. The Commission's competitiveness compass - fixated on metrics and control - reveals dangerous left-hemisphere dominance, echoing Maoist central planning's epistemological errors. Our path forward demands:
* Dual-brain governance (prioritising creativity over control)
* Banishing of category mistakes (acknowledging the complex adaptive nature of the economy)
* Pragmatism over ideology (policy sandboxes inspired by China's special economic zones)
* Anti-fragile design (increased autonomy of EU nations, within states, and decentralised banking)
* Sunset clauses on all bureaucracy (regulators cannot originate breakthroughs)
The alternative? Another technocratic Great Leap Forward - eco-certified, AI-monitored, but economically brittle and fundamentally maladapted to the complex global economy. **As Deng's reformers understood: no institutional architecture, not even the First Emperor's Terracotta Army, can withstand modernity's tide.**
