2025-03-18T20:44:01Z

Amazing read of tough questions for Nostr. All the rumination here make a lot of sense although I was caught off guard at first by some of the questions/statements.

quoting naddr1qq…eucy

In 2024, I was high as a kite on Nostr hopium and optimism. Early that year, my co-founder and I figured that we could use Nostr as a way to validate ambassadors on “Destination Bitcoin” - the germ of a travel app idea we had at the time that would turn into Satlantis. After some more digging and thinking, we realised that Nostr’s open social graph would be of major benefit, and in exploring that design space, the fuller idea of Satlantis formed: a new kind of social network for travel.

###### ^^2 slides from the original idea here

I still remember the call I had with @pablof7z in January. I was in Dubai pitching the AI idea I was working on at the time, but all I could think and talk about was Satlantis and Nostr.

That conversation made me bullish AF. I came back from the trip convinced we’d struck gold. I pivoted the old company, re-organised the team and booked us for the Sovereign Engineering cohort in Madeira. We put together a whole product roadmap, go to market strategy and cap raise around the use of Nostr. We were going to be the ‘next big Nostr app’.

A couple of events followed in which I announced this all to the world: Bitcoin Atlantis in March and BTC Prague in June being the two main ones. The feedback was incredible. So we doubled down. After being the major financial backer for the Nostr Booth in Prague, I decided to help organise the Nostr Booth initiative and back it financially for a series of Latin American conferences in November. I was convinced this was the biggest thing since bitcoin, so much so that I spent over $50,000 in 2024 on Nostr marketing initiatives. I was certainly high on something.

Sobering up

It’s March 2025 and I’ve sobered up. I now look at Nostr through a different lens. A more pragmatic one. I see Nostr as a tool, as an entrepreneur - who’s more interested in solving a problem, than fixating on the tool(s) being used - should.

A couple things changed for me. One was the sub-standard product we released in November. I was so focused on being a Nostr evangelist that I put our product second. Coupled with the extra technical debt we took on at Satlantis by making everything Nostr native, our product was crap. We traded usability & product stability for Nostr purism & evangelism.

We built a whole suite of features using native event kinds (location kinds, calendar kinds, etc) that we thought other Nostr apps would also use and therefore be interoperable. Turns out no serious players were doing any of that, so we spent a bunch of time over-engineering for no benefit 😂

The other wake up call for me was the Twitter ban in Brazil. Being one of the largest markets for Twitter, I really thought it would have a material impact on global Nostr adoption. When basically nothing happened, I began to question things.

Combined, these experiences helped sober me up and I come down from my high. I was reading “the cold start problem” by Andrew Chen (ex-Uber) at the time and doing a deep dive on network effects. I came to the following realisation:

Nostr’s network effect is going to take WAY longer than we all anticipated initially. This is going to be a long grind. And unlike bitcoin, winning is not inevitable. Bitcoin solves a much more important problem, and it’s the ONLY option. Nostr solves an important problem yes, but it’s far from the only approach. It’s just the implementation arguably in the lead right now.

This sobering up led us to take a different approach with Nostr. We now view it as another tool in the tech-stack, no different to the use of React Native on mobile or AWS for infrastructure. Nostr is something to use if it makes the product better, or avoid if it makes the product and user experience worse. I will share more on this below, including our simple decision making framework. I’ll also present a few more potentially unpopular opinions about Nostr. Four in total actually:

Nostr is a tool, not a revolution

Nostr doesn’t solve the multiple social accounts problem

Nostr is not for censorship resistance

Grants come with a price

Let’s begin…

Nostr is a tool, not a revolution

Nostr is full of Bitcoiners, and as much as we like to think we’re immune from shiny object syndrome, we are, somewhere deep down afflicted by it like other humans. That’s normal & fine. But…while Bitcoiners have successfully suppressed this desire when it comes to shitcoins, it lies dormant, yearning for the least shitcoin-like thing to emerge which we can throw our guiltless support behind.

That thing arrived and it’s called Nostr.

As a result, we’ve come to project the same kind of purity and maximalism onto it as we do with Bitcoin, because it shares some attributes and it’s clearly not a grift.

The trouble is, in doing so, we’ve put it in the same class as Bitcoin - which is an error.

Nostr is important and in its own small way, revolutionary, but it pales in comparison to Bitcoin’s importance. Think of it this way: If Bitcoin fails, civilisation is fucked. If Nostr fails, we’ll engineer another rich-identity protocol. There is no need for the kind of immaculate conception and path dependence that was necessary for Bitcoin whose genesis and success has been a once in a civilisation event. Equivocating Nostr and Bitcoin to the degree that it has been, is a significant category error. Nostr may ‘win’ or it may just be an experiment on the path to something better. And that’s ok !

I don’t say this to piss anyone off, to piss on Nostr or to piss on myself. I say it because I’d prefer Nostr not remain a place where a few thousand people speak to each other about how cool Nostr is. That’s cute in the short term, but in the grand scheme of things, it’s a waste of a great tool that can make a significant corner of the Internet great again.

By removing the emotional charge and hopium from our relationship to Nostr, we can take a more sober, objective view of it (and hopefully use it more effectively).

Instead of making everything about Nostr (the tool), we can go back to doing what great product people and businesses do: make everything about the customer.

Nobody’s going around marketing their app as a “react native product” - and while I understand that’s a false equivalent in the sense that Nostr is a protocol, while react is a framework - the reality is that it DOES NOT MATTER.

For 99.9999% of the world, what matters is the hole, not the drill. Maybe 1000 people on Earth REALLY care that something is built on Nostr, but for everyone else, what matters is what the app or product does and the problem it solves. Realigning our focus in this way, and looking at not only Nostr, but also Bitcoin as a tool in the toolkit, has transformed the way we’re building.

This inspired an essay I wrote a couple weeks ago called “As Nostr as Possible”. It covers our updated approach to using and building WITH Nostr (not just ‘on’ it). You can find that here:

https://futuresocial.substack.com/p/as-nostr-as-possible-anap

If you’re too busy to read it, don’t fret. The entire theory can be summarised by the diagram below. This is how we now decide what to make Nostr-native, and what to just build on our own. And - as stated in the ANAP essay - that doesn’t mean we’ll never make certain features Nostr-native. If the argument is that Nostr is not going anywhere, then we can always come back to that feature and Nostr-fy it later when resources and protocol stability permit.

Next…

The Nostr all in one approach is not all “positive”

Having one account accessible via many different apps might not be as positive as we initially thought.

If you have one unified presence online, across all of your socials, and you’re posting the same thing everywhere, then yes - being able to post content in one place and it being broadcast everywhere, is great. There’s a reason why people literally PAY for products like Hypefury, Buffer and Hootsuite (aside from scheduling).

BUT…..This is not always the case.

I’ve spoken to hundreds of creators and many have flagged this as a bug not a feature because they tend to have a different audience on different platforms and speak to them differently depending on the platform. We all know this. How you present yourself on LinkedIn is very different to how you do it on Instagram or X.

The story of Weishu (Tencent’s version of TikTok) comes to mind here. Tencent’s WeChat login worked against them because people didn’t want their social graph following them around. Users actually wanted freedom from their existing family & friends, so they chose Douyin (Chinese TikTok) instead.

Perhaps this is more relevant to something like WeChat because the social graph following you around is more personal, but we saw something similar with Instagram and Facebook. Despite over a decade of ownership, Facebook still keeps the social graphs separated.

All this to say that while having a different strategy & approach on different social apps is annoying, it allows users to tap into different markets because each silo has its own ‘flavour’. The people who just post the same thing everywhere are low-quality content creators anyway. The ones who actually care, are using each platform differently.

The ironic part here is that this is arguably more ‘decentralised’ than the protocol approach because these siloes form a ‘marketplace of communities’ which are all somewhat different.

We need to find a smart way of doing this with Nostr. Some way of catering to the appropriate audience where it matters most. Perhaps this will be handled by clients, or by relays. One solution I’ve heard from people in the Nostr space is to just ‘spin up another nPub’ for your different audience. While I have no problem with people doing that - I have multiple nPubs myself - it’s clearly NOT a solution to the underlying problem here.

We’re experimenting with something. Whether it’s a good idea or not remains to be seen. Satlantis users will be able to curate their profiles and remove (hide / delete) content on our app. We’ll implement this in two stages:

Stage 1: Simple\ In the first iteration, we will not broadcast a delete request to relays. This means users can get a nicely curated profile page on Satlantis, but keep a record of their full profile elsewhere on other clients / relays.

Stage 2: More complex\ Later on, we’ll try to give people an option to “delete on Satlantis only” or “delete everywhere”. The difference here is more control for the user. Whether we get this far remains to be seen. We’ll need to experiment with the UX and see whether this is something people really want.

I’m sure neither of these solutions are ‘ideal’ - but they’re what we’re going to try until we have more time & resources to think this through more.

Next…

Nostr is not for Censorship Resistance

I’m sorry to say, but this ship has sailed. At least for now. Maybe it’s a problem again in the future, but who knows when, and if it will ever be a big enough factor anyway.

The truth is, while WE all know that Nostr is superior because it’s a protocol, people do NOT care enough. They are more interested in what’s written ON the box, not what’s necessarily inside the box. 99% of people don’t know wtf a protocol is in the first place - let alone why it matters for censorship resistance to happen at that level, or more importantly, why they should trust Nostr to deliver on that promise.

Furthermore, the few people who did care about “free speech” are now placated enough with Rumble for Video, X for short form and Substack for long form. With Meta now paying lip-service to the movement, it’s game over for this narrative - at least for the foreseeable future.

The "space in people’s minds for censorship resistance has been filled. Both the ‘censorship resistance’ and ‘free speech’ ships have sailed (even though they were fake), and the people who cared enough all boarded.

For the normies who never cared, they still don’t care - or they found their way to the anti-platforms, like Threads, BlueSky or Pornhub.

The small minority of us still here on Nostr…are well…still here. Which is great, but if the goal is to grow the network effect here and bring in more people, then we need to find a new angle. Something more compelling than “your account won’t be deleted.”

I’m not 100% sure what that is. My instinct is that a “network of interoperable applications”, that don’t necessarily or explicitly brand themselves as Nostr, but have it under the hood is the right direction. I think the open social graph and using it in novel ways is compelling. Trouble is, this needs more really well-built and novel apps for non-sovereignty minded people (especially content creators) and people who don’t necessarily care about the reasons Nostr was first built. Also requires us to move beyond just building clones of what already exists.

We’ve been trying to do this Satlantis thing for almost a year now and it’s coming along - albeit WAY slower than I would’ve liked. We’re experimenting our way into a whole new category of product. Something different to what exists today. We’ve made a whole bunch of mistakes and at times I feel like a LARP considering the state of non-delivery.

BUT…what’s on the horizon is very special, and I think that all of the pain, effort and heartache along the way will be 100% worth it. We are going to deliver a killer product that people love, that solves a whole host of travel-related problems and has Nostr under the hood (where nobody, except those who care, will know).

Grants come with a price

This one is less of an opinion and more of an observation. Not sure it really belongs in this essay, but I’ll make a small mention just as food for thought,

Grants are a double-edged sword.

I’m super grateful that OpenSats, et al, are supporting the protocol, and I don’t envy the job they have in trying to decipher what to support and what not to depending on what’s of benefit to the network versus what’s an end user product.

That being said, is the Nostr ecosystem too grant-dependent? This is not a criticism, but a question. Perhaps this is the right thing to do because of how young Nostr is. But I just can’t help but feel like there’s something a-miss.

Grants put the focus on Nostr, instead of the product or customer. Which is fine, if the work the grant covers is for Nostr protocol development or tooling. But when grants subsidise the development of end user products, it ties the builder / grant recipient to Nostr in a way that can misalign them to the customer’s needs. It’s a bit like getting a government grant to build something. Who’s the real customer??

Grants can therefore create an almost communist-like detachment from the market and false economic incentive. To reference the Nostr decision framework I showed you earlier, when you’ve been given a grant, you are focusing more on the X axis, not the Y. This is a trade-off, and all trade-offs have consequences.

Could grants be the reason Nostr is so full of hobbyists and experimental products, instead of serious products? Or is that just a function of how ambitious and early Nostr is?

I don’t know.

Nostr certainly needs better toolkits, SDKs, and infrastructure upon which app and product developers can build. I just hope the grant money finds its way there, and that it yields these tools. Otherwise app developers like us, won’t stick around and build on Nostr. We’ll swap it out with a better tool.

To be clear, this is not me pissing on Nostr or the Grantors. Jack, OpenSats and everyone who’s supported Nostr are incredible. I’m just asking the question.

Final thing I’ll leave this section with is a thought experiment: Would Nostr survive if OpenSats disappeared tomorrow?

Something to think about….

Coda

If you read this far, thank you. There’s a bunch here to digest, and like I said earlier - this not about shitting on Nostr. It is just an enquiry mixed with a little classic Svetski-Sacred-Cow-Slaying.

I want to see Nostr succeed. Not only because I think it’s good for the world, but also because I think it is the best option. Which is why we’ve invested so much in it (something I’ll cover in an upcoming article: “Why we chose to build on Nostr”). I’m firmly of the belief that this is the right toolkit for an internet-native identity and open social graph. What I’m not so sure about is the echo chamber it’s become and the cult-like relationship people have with it.

I look forward to being witch-hunted and burnt at the stake by the Nostr purists for my heresy and blaspheming. I also look forward to some productive discussions as a result of reading this.

Thankyou for your attention.

Until next time.

quoting note13d2…f3nk
There are those who come here with certain expectations (images don't load, can't find users, DM privacy sucks, no blue checkmarks, ...) and a conflicted mind that doesn't let them enjoy the freedom of chaos. They need it to be wrong and broken so they can handle the dissonance when going back to Elon's private global hellscape.

Then there are those who come and see an infinite space of possibilities and also challenges, they see the beauty in the chaos. They know that this protocol owes them exactly nothing.

They ask: what can I do with nostr what has never been done before? And slowly they realize how big this question really is.

Olha o que o deepseek falou. Tenho que estudar ainda PTLC então não consigo filtrar tão bem a resposta.

Para resolver o problema de **pagamentos atômicos sem revelar a preimagem publicamente**, podemos usar uma combinação de **criptografia assimétrica** e **mecanismos de compromisso (commitments) adaptados**, evitando os limites dos HTLCs (Hash Time-Locked Contracts) tradicionais. Aqui está uma proposta detalhada:

---

### **Solução: PTLCs (Point Time-Locked Contracts) com Criptografia Híbrida**
Os **PTLCs** são uma evolução dos HTLCs, usando assinaturas Schnorr e **adaptor signatures** para garantir atomicidade sem revelar a preimagem publicamente. Combinamos isso com criptografia assimétrica para entregar a chave de descriptografia apenas ao comprador.

---

#### **Passo a Passo do Protocolo**

1. **Geração de Chaves e Parâmetros:**
- **Comprador (Alice):** Gera um par de chaves pública/privada `(P_A, s_A)`.
- **Vendedor (Bob):** Gera um segredo `k` (preimagem) e um nonce `r`, e calcula `R = r*G` (ponto na curva elíptica).
- **Bob:** Deriva uma chave simétrica `s = H(k)` para criptografar a chave do produto.

2. **Commitment do Produto:**
- **Bob:** Criptografa a chave do produto `K` usando `s`, gerando `C = Enc(K, s)`.
- **Bob:** Compromete-se a `C` e `R` em um canal público (ex: DHT, IPFS) ou no próprio contrato.

3. **Configuração do PTLC:**
- **Bob:** Cria uma **adaptor signature** vinculada a `R` para uma transação que paga Alice se ela revelar `k`.
- O contrato inteligente verifica a assinatura e bloqueia os fundos com uma condição: para resgatar, Alice deve fornecer uma assinatura válida que inclua `k`.

4. **Pagamento e Revelação da Chave:**
- **Alice:** Envia o pagamento para o contrato, que só é concluído se Bob fornecer `C` e uma prova de que `C` está corretamente vinculada a `R`.
- **Bob:** Revela `C` e `R` para Alice via canal off-chain (ex: Lightning Network) ou on-chain (dependendo da privacidade desejada).
- **Alice:** Usa `k` (extraído da adaptor signature) para derivar `s = H(k)`, descriptografar `C` e obter `K`.

5. **Verificação Final:**
- **Alice:** Verifica se `K` descriptografa o produto corretamente. Se sim, o contrato libera os fundos para Bob. Caso contrário, Alice pode recuperar seu BTC após um timeout.

---

#### **Vantagens**
- **Privacidade da Preimagem:** A preimagem `k` nunca é exposta on-chain. Apenas Alice e Bob conhecem `k`.
- **Atomicidade:** O pagamento e a entrega de `K` são atômicos: ou ambos acontecem, ou nenhum.
- **Sem Confiança:** Nenhuma das partes precisa confiar na outra, apenas no código do contrato.

---

#### **Ferramentas e Tecnologias**
1. **Bitcoin Script:** Para criar PTLCs usando Schnorr/Taproot.
2. **Adaptor Signatures:** Permitem vincular a liberação de `k` à conclusão do pagamento.
3. **Criptografia Híbrida:** Combina criptografia simétrica (AES-GCM) para `K` e assimétrica (ECDH) para compartilhar `s`.
4. **Armazenamento Off-Chain:** Usar redes como Lightning Network ou sistemas P2P para entregar `C` e `R`.

---

#### **Exemplo de Implementação Simplificada**
```python
# Bob gera segredo k e nonce R
k = random()
R = k * G

# Criptografa a chave K
s = SHA256(k)
C = AES.encrypt(K, s)

# Contrato PTLC (Bitcoin Script com Taproot)
def redeem(alice_sig, bob_sig, k):
assert verify_adaptor(alice_sig, bob_sig, R, k)
return True

# Alice descriptografa K após obter k do PTLC
s_recovered = SHA256(k)
K = AES.decrypt(C, s_recovered)
```

---

#### **Considerações de Segurança**
- Use **canais confiáveis** para comunicação off-chain (ex: Lightning).
- Adicione **timeouts** para evitar bloqueio eterno de fundos.
- Valide sempre a integridade do produto após descriptografia (ex: via hash do conteúdo).

Essa abordagem mantém a preimagem privada, garante atomicidade e elimina a necessidade de confiança, resolvendo o problema original de forma elegante.

I'm proud to now reveal what luisschwab (npub1d2x…eu8n) and I have been working on:

🥣 𝗚𝗿𝗮𝗻𝗼𝗹𝗮: a Cashu based exchange.

With Granola you'll be able to buy and sell Bitcorn with the same privacy assurances of Cashu.

Let me tell you how it works 👇

Just like regular granola is a mixture of nuts, cereals and other stuff, 𝗚𝗿𝗮𝗻𝗼𝗹𝗮 takes Bitcorn, Cashu, and other things so you can mix them up with Atomic Cross-Mint Swaps.
🌰 🥜 🌽 🌾
⬇️
🥣

For the curious nerds out there that want to go deeper, this is how the Atomic Cross Mint Swaps work.

We are already integrating with the guys from DePix, so you can send fiat and we still won't have any idea of who you are and what you are doing.

We are creating this project for Satsconf (npub1ze9…3pxq) hackathon so if you like it, please boost it until it reaches the hackathon judges!

Aproveitando, segue uma análise que fiz com os dados deste nosso ciclo de agora usando a lei de Zipf-Mandelbrot.

O maior retorno diário do 5º ciclo foi de 12.76% e o próximo maior retorno diário do 5º ciclo será em torno de: 17.03% ± 3.39%
O pior retorno diário do ciclo foi -6.80% e o próximo pior retorno diário do ciclo será em torno de: -10.60% ± 3.11%

_________________________

I have an opinion on this. I studied german for some months in Brazil and in Berlin and it's not a particularly difficult language. People find it hard because:

1. It's portrayed as hard, with hard sounds, and it's famous for being terrifying;
2. It's the only main western language that has declension. I actually understood what are these cases after I studied Czech, which had 7 cases for everything, while German have 4 only for articles. Depending on the teacher you had, it's very hard to understand what is the difference between the dative and accusEative cases; and
3. Germans are tough nitpickers. While, for most languages, natives don't speak correctly the formal grammar and are just happy that someone else is trying to learn their language and usually encourage them saying "wow, your <language> is perfect! I can't believe you are a foreigner", Germans seem to speak correctly with the formal rules and will try to correct every minor mistake you make even minor pronunciation differences.

So although Czech is extremely more difficult than German, I found more difficult to study and practice German.

Apart from that it's not difficult.

It's easy to understand how to contribute being a dev: you look at the issues list on github and write code to fix them.

However, it's not so easy to understand how you start contributing as a project manager in an open source project where there's no hierarchy nor regular jobs.

Why and how the devs would want to be managed by me? I'd love to understand that better.
