- stored somewhere in the cloud or on nostr
- web, ios, android apps to read all your stored articles

I'm not saying this to offend you anon. You're probably a great dev, and I'm probably using your software. I'm grateful for all the work you're putting in.
This isn't meant to criticize you personally. I am simply stating an observation as a user who has been around here from the very early days. I'm pointing at a problem that has to do with how the collective works. It's not enough to sign JSONs and pray, a serious project needs direction and a vision.
Nostr, as a sum of its developers and visionaries, had this for a while. It doesn't have it anymore. I hope we can discover it again.

2026-09-07 14:41:40 UTC

While I'm at it – another proof that nostr devs aren't serious about adoption is still the lack of key rotation.
I get it. It's a big task and can't be solved by any individual client, it needs to be addressed on a protocol level. I'm also aware of the that were put forward. But you know what? Writing markdown and pushing it to the nips repo isn't enough. It's step 0.
This is a typical issue that would require devs to come together and all pull in one direction. It likely would have needed a champion who is willing to push for this change, talk to people, explain it to everyone, and actually care. Similar to how we push for bigger changes in the Bitcoin protocol. It takes time, and it takes a serious effort. Once again, nobody has taken over that role because nobody really cared enough.
Back in the day, there were massively big users who would've loved to join nostr – but didn't do it because of a lack of key rotation. Why would anyone with so much to lose join a protocol that can permanently rekt your identity with a simple XSS bug that exposes your nsec? Nobody listened to them.
This was brought up over, and over, and over again. Nobody cared enough.

2026-09-07 14:29:15 UTC

@nprofile…uz3y has a serious issue with muting users – it can't be that hard. The only client I haven't had issues is @nprofile…4hdy
Many nostr kind-0 devs don't realize how big of an issue this is for their users because they don't put themselves into the shoes of ordinary users who don't want to deal with this shit.

you realize that liquid is a 11 of 15 federation?

2026-09-07 11:32:51 UTC

- reply

of course it makes sense

2026-09-07 09:37:23 UTC

Liquid hack explained.
Liquid has confidential transactions that hide the amounts for improved privacy. A bug in how these transactions are validated caused inflation of Liquid BTC (L-BTC) and allowed hackers to empty the entire side chain.
Liquid nodes don't see the amounts of a confidential transaction, so to make sure that the transaction is still valid and doesn't cause inflation nodes check something called a balance proof and a range proof.
The balance proof establish that sum of the input amounts equal the output amounts, i.e., that "x L-BTC going in and x L-BTC going out". But there's a catch. Only relying on a balance proof isn't enough. You also need the range proof.
The range proof establishes that a hidden output amount falls within a positive range. That means a valid output must be at least 1 L-sat and at most 2^64 − 1 L-sats. Range proofs make sure that you can't mint "negative L-BTC".
Why is this even necessary? Remember, the amounts are hidden and a hidden negative amount would allow extra positive outputs to balance against it. Without a range proof, a transaction could say "I've put 1 L-BTC in, and I'm taking two outputs out: one with 4000 L-BTC and one with -3999 L-BTC)."
This is going to cause a disaster in a little bit.
Once the balance proof, the range proof, and other validations pass, a transaction is regarded as valid and can pass consensus. However, because especially the range proof is computationally expensive, Liquid nodes cache the result of a successful range proof in memory. Essentially, the node remembers "I saw this range proof before and it was valid, all good!".
In order to recognize the same range proof later on, you need to assign a label to it. This is called a cache key. This cache key is the actual cause of the bug.
The way this cache key was constructed allowed two different transactions to collide on their cache key. Essentially, one valid transaction (1 L-BTC in, 1 L-BTC out) had the same cache key as an invalid transaction (1 L-BTC in, 4000 L-BTC out).
Here's the hack: the attackers submitted the valid transaction (1 L-BTC in, 1 L-BTC out) first. Liquid nodes verified this transaction successfully, created a cache key called REKT and stored it in their cache. Then the attackers carefully crafted a second invalid transaction with (1 L-BTC in, 4000 L-BTC out) that created the same cache key REKT.
Instead of validating the second transaction and realizing that it printed money out of thin air, Liquid nodes found it in their cache and said "hey I saw this transaction before, everything is fine" and that caused the inflation.
The attackers then took their 4000 L-BTC and withdrew 4000 BTC onto the Bitcoin base chain.

why humans should not code in c: we're finding memory-safety vulnerabilities in c projects that are prevented by default in many other languages.
in the past, finding a simple buffer overflow wasn't enough. you'd need a highly skilled hacker to turn the vulnerability into a working end-to-end exploit.
today, that's a single prompt.

gained a ton of new insights working in bitcoin red team 🟥 that i wish i could share without vague posting. but this is what i got anon.
- we’re experiencing a massive collision between decades of human open source slop against 2 weeks of kimi k3 (not good)
- everything is broken, bitcoin is burning
- bitcoin is becoming stronger through this
- bitcoin is the obvious first target but the rest of the world will follow shortly
- sometimes old things need to burn so new things can grow on healthy soil
- humans should never code in c (just stop)
- lightning is complicated and is more broken than the average (sorry)
- verification is free. we used to complain about slop PRs. then about slop security audits. if you can’t handle the information overload, stop complaining and use AI to sort through it.
- those projects that started AI audits months ago are in a completely different position than those who didn’t
- projects need their own AI audit pipeline going into the future
- the burden for a developer to keep software safe and secure is pretty stressful and not for everyone. it has become a lot more stressful now.
- unmaintained projects are most probably broken, don’t rely on them. i’d rather one-shot it myself with a modern AI
- multiple concurrent, diverse human approaches have proven to be the best vulnerability search method
- external red teaming will probably have to continue forever
- we’ve basically completed a basic scan of virtually the entirety of bitcoin open source. the low hanging fruit is done.
- we’ve reported a ton of real critical and high vulnerabilities. project maintainers across the board have validated our findings.
- response speed is very different across projects and shows how healthy each project is. i recommend acting fast these days.
- red team etiquette matters. if you don’t disclose responsibly, boast on twitter about your findings on a particular project, or make indications about the nature of particular findings, you’ve disqualified yourself as a serious security researcher. trust is the most important factor in this game. if you lose it, it’s very hard to win it back.
- did i mention that humans should not code in c?

2026-07-31 12:37:51 UTC

This is worse than any previous Bitcoin exchange hack. It is arguably one of the worst things that could happen.
The popular hardware wallet COLDCARD has a faulty random number generator (RNG). Funds are being drained from ordinary users’ hardware wallets as you read this.
Users first reported to Block less than 24 hours ago that funds were moving out of their wallets. The exploit was most likely discovered with the help of AI. Block has confirmed that the RNG is broken. You know what that means.
There are likely already multiple attackers competing for the affected BTC. Many more will join very soon.
Nobody knows how much BTC is affected.
Nobody knows how many users are affected.
This attack has only just begun, and it will continue until all affected BTC has been drained unless users secure their funds first. Inevitably, many Bitcoiners will not hear about the incident early enough to respond in time.
I am truly saddened for everyone affected, especially those who may have just lost their life savings.
The worst part is that they did everything right.
