I tried it last week. The mobile client is solid but still a bit glitchy — about on par with Nostr mobile, in my experience. I’d expect a public release in June once they’ve ironed out the bugs.
As for Nostr’s censorship-resistance claims — they’re pretty weak. When real Bitcoin-level censorship resistance was on the table, there wasn’t much interest. The focus seems to be on building a Twitter clone, which makes sense given that most of the ecosystem is funded by Twitter’s founder.

#pubky is like your npub with DNS. So from your public key, you go to the bittorrent network and run a query, then you get out a DNS record. So instead of domain_tld you have pubky to create a decentralized web. It can also store files, run relays, serve media and do all the things the web can currently do (including nostr).

No, dont put art on-chain. It was not designed for that. Node runners have every right to complain about that. Put a reference to the art, and store it with nostr, or blossom, or nosdav. It's a win-win.

Two levels of censorship-resistance are emerging via open protocols. One is the dns-censorship-resistance model (nostr et al 2020) which is the same model as the current web w/ replication, and subject to take downs.
The second model is the bittorrent-censorship reistance model of the web (pkarr, pubky et al c. 2025) which seems to be holding its own, even against take down requests.
It's trivial to upgrade users to offer both level of censorshp-resistance for nostr devs. And it will be interesting to see which clients are the first upgrade their censorship resistance, and which are the last.
I think we're moving from a first gen nostr which was a proof of concept. To a second gen which actually is verifiably censorship resistant and is scale free. Exciting!

2025-03-29 01:04:42

They said it was impossible! But, as of today we have de-facto solved a long-standing problem in computer science. And that is of decentralized global naming, that is human readable, and fair.
1. Register a name on the bitcoin block chain, on a first-come, first-served basis
2. Name is in an OP_RETURN and human readable
3. That name has an npub associated with it.
4. The npub publishes the name to nostr relays, and also has a pubky
5. The name is globally resolvable using pubky protocol, and has bittorrent level censorship resistance
A truly censorship-resistant, human-readable, naming system that includes decentralized DNS. Quite an achievment!

consider that nostr should integrate on-chain bitcoin because they are both taproot, and how powerful that could be

2025-03-28 13:17:14

First impressions of #pubky vs #nostr
mobile experience: pubkey is better than nostr
desktop experience: nostr is better than pubky
key management: nostr nsec is easier than 12 word seeds
on boarding: pubky feels new and glitchy, but they are fixing things, nostr is more polished, glitches take longer to fix
Still only day 1, but imho a great new addition to the open web. Cant wait to see how it evolves and for the public launch.

2025-03-28 10:53:56

In retrospect, the main value of did-nostr is its ability to unify Nostr and Bitcoin primitives within a single JSON object. This not only enables a 10x–100x architectural scaling potential for both systems, but also unlocks advanced use cases like on-chain zaps, trustless atomic swaps, decentralized contracts, consistent profiles and agentic Nostr.
That said, I’m not entirely satisfied with the current DID spec—there are a couple of tweaks that would make a real difference. Still, it’s a significant improvement over what we have today, and those edge cases can be fixed later.

By the way I think techniques like this will become invaluable for projects like bitcoin. Especially if we can learn to subtract biases introduced by the group think. If bitcoin development could return to its roots of logical arguments to optimize the system, rather than, advocacy and politics. We could pave a cow-path towards ossification, while mitigating major risks, such as a chain-split.

Nice gimmick here, where two Agents talk using a modem type language. This is how the internet worked in the early days using modems and BAUD rate. Faster today, to use a web socket, like nostr does. But it is nice to imagine agents having their own laguage,which a few of us are currently working on.

It makes sense, but decentralization isnt a binary thing both bluesky and nostr have different types of centralization. Nostr right now relies on subsidies. Bluesky has grown from smaller than nostr to 100x the size last year. And probably 1000x the size next year. While nostr has gone sideways in the last year. If nostr had a bigger user base e.g. 10x or even 2x, it would be less dependent on subsidies (which also causes competition) and be more sustainable. I hope nostr is open to learning from others who have achieved success.

Not sure the rules are impossible to change. If enough people are persuaded to change a rule, then you would get a chain split, with different rules. That has already happened in the past. And it is probably the biggest threat in the short term.

OASIS: Open Agents Social Interaction Simulations on One Million Agents
There has been a growing interest in enhancing rule-based agent-based models (ABMs) for social media platforms (i.e., X, Reddit) with more realistic large language model(LLM) agents, thereby allowing for a more nuanced study of complex systems. As a result, several LLM-based ABMs have been proposed in the past year. While they hold promise, each simulator is specifically designed to study a particular scenario, making it time-consuming and resource-intensive to explore other phenomena using the same ABM. Additionally, these models simulate only a limited number of agents, whereas real-world social media platforms involve millions of users. To this end, we propose OASIS, a generalizable and scalable social media simulator. OASIS is designed based on real-world social media platforms, incorporating dynamically updated environments(i.e., dynamic social networks and post information), diverse action spaces(i.e., following, commenting), and recommendation systems(i.e., interest-based and hot-score-based). Additionally, OASIS supports large-scale user simulations, capable of modeling up to one million users. With these features, OASIS can be easily extended to different social media platforms to study large-scale group phenomena and behaviors. We replicate various social phenomena, including information spreading, group polarization, and herd effects across X and Reddit platforms. Moreover, we provide observations of social phenomena at different agent group scales. we observe that the larger agent group scale leads to more enhanced group dynamics and more diverse and helpful agents' opinions.

Sounds great! I’ve always been a fan of Oshash for media—it integrates so well with the OpenSubtitles ecosystem, which has most of the world’s content indexed. I remember it was quite a challenge and even a bit controversial when they switched to a better hashing algorithm. I think the resistance came from the sheer scale of the ecosystem and the compatibility issues involved, but it’s impressive how they made it work in the end!

It’s a great and super-fast algorithm, especially the WASM implementation! But until it’s bundled by default in Linux, other major OSes, and browsers, it’s unlikely to go mainstream. Switching algorithms is pretty tricky once you’ve committed to one. Still, Blake3 is definitely impressive!

Cool initiative. Looking at the github issue the last post says: "Active user counts are still low". So perhaps there is interest but it's not a priority yet.
One good thing would be if opensats developed a growth strategy. That is something that has worked well for nostr's rivals, which are part of bridgy.

I find it really difficult to understand the thinking here. Nostr privkeys are both nostr keys and git keys. But the argument I want to use them only as nostr keys, rather than use them both nostr keys and git keys, I cannot see as a technical argument. I just cant see it. It's like having the number "2" and saying, we can use that to add, but not to multiply. It's a thought process that I find alien, and see no way past it.

There's not much to it really. It's just an ed25519 key which has the same 64 byte hex string that nostr does for its privkey. So nostr already has an an ed25519 privkey which is native to git. It can do commits, ssh, clones, git identity etc. The #pubky is simply a base32 encoded public key in the profile (just like npub but better, without the unnecessary segwit checksum). So every nostr account gets both functionalities. Perfect for git.
