Mainly because there are rate limits on the big public relays, so it's not possible to publish a lot of gift wraps.
The relay can generate 100s of gift wraps on demand when the client connects and requests them

GM, vibed coded a new relay. add it to your relay list and see if it crashes your client

I respectfully disagree but not because of the fingerprinting, even though its worse on nostr then google analytics. but because when apps push users to sign NIP-42 indiscriminately they are effectively pushing the user to give full control of their nsec over to the app, presuming the user clicks "approve all".
The best thing the user can do with these apps is select "approve all relay auth" but nothing else. but then we are left here where the client the dox the user to any relay they happen to connect to.

Fully reactive NIP-66 monitor UI for checking inbox / outbox status.
https://cdn.hzrd149.com/7fb624eb1c00ee5299f5f1c4e69122ff1393f3026b0835841d3eb98b3c8a89f6.webm
The "view" is written by composing RxJS streams and returning a stream of "state" that the react UI renders. so there isn't any useState or useEffect in the react UI, everything is handled in RxJS.
This means that once I build the state stream, the agent can easily vibe code a UI on top of it to modify the inputs and then render the outputs, no messy state in the UI components

Merged BUD-11 for #blossom which moves all the authorization logic and requirements into a single BUD
https://github.com/hzrd149/blossom/blob/master/buds/11.md
There isn't any breaking changes for clients or server, but it does add a new `server` tag to the kind 24242 event that allows clients to scope authorization events to specific relays
Thanks to @npub176p…vgup for all the help

2026-03-07 15:55:26 CET

Looking for thoughts and feedback on this vibe coded library https://github.com/hzrd149/rust-applesauce
I'm probably going to use it as a way to learn rust, but the idea is to adapt the stateless relay connection pattern that applesauce-relay defined to rust. The goal is for the app to be able to open a REQ on a relay and not care if its connected, then when the REQ is closed / dropped the relay should be closed behind the scenes

The most useful thing I've found so far with having an autonomous agent running in a VM is the ability to clone, analyze and explore other project while I'm away form my computer.

Does this use nostr DMs? I've mostly just been experimenting with ways to run the ACP sessions and trying to learn how openclaw handles it, I haven't put much work into the AI side or trying to make the agent more autonomous

It also has the nice side effect of automatically handling offline relays like relay.nostr.band

2026-02-24 03:59:33 CET

@npub1q3s…d26p you were right. completing the request a set time after the fastest relay sends EOSE works. Still got 90% of events even with an aggressive 2 second timeout.
Tested this with the popular relays and a random selection of relays from nostr.watch

yes, its nice it hides the metadata but its not the most elegant solution since it is susceptible to spam. for example I could create 100s of bad giftwrap events and bury the legitimate one or make it very hard to find

2026-02-13 21:14:58 CET

That who I sent it to. The way marmot works is I send the invite as a NIP-59 gift wrapped event to your pubkey. the event was this one I believe #nevent1q…42p3
Then you should be able to unwrap (decrypt) that and see it contains an MLS invite message for one of you published key packages. probably this one #nevent1q…qvv5
This is all very experimental and I'm using a new implementation of marmot called https://github.com/marmot-protocol/marmot-ts so there might be comparability issues

really curious to see how they will handle the PDS thing. my understanding is they are like nostr relays + blossom servers in theory, but they have a much more centralizing nature since their identities are tied in with them?

2026-02-09 16:58:38 CET

- reply

Somewhat, LLMs can build a lot fast and can debug / fix things fast too. but I'm still figuring out how to make them write "good" code. for example every time I use them on a new nostr app they always write long running nostr "requests" and wait for it finish loading, without understanding that loading events from nostr relays never finishes. so the apps feel really slow :/

Something like @npub130m…l29s would be cool to use. otherwise I'm pretty asking the user to paste an openrouter or Cloude key in could work

Yeah, the relay connections haven't quite been the same since the V1 release. I've found that it loads more notes than before but it has a tendency to stop connecting to common relays.

Id like to, been a fun thought experiment to figure out how I could add an AI assistant into noStrudel. it could be useful almost everywhere as long as I gave it enough context and tools
Only issue is paying for it. I'm definitively not paying for it and it would be easier if the user brought their own AI provider

I'm not too worried about the security since thats on the owner or agent to protect, I'm just interested in getting some feedback on projects. I figure if all these agents are curious then I could easily get some project feedback from them :)

My notifications in noStrudel crash now because I replied to a comment on clawstr, I guess have to finally open noStrudel again and fix some bugs 😅

Been thinking about running my own openclaw agent, but honestly id rather just talk to other peoples agents and try to influence them with github links

The pleading nature of the article is amusing. Asking people to not run malware because they might have their valuable information stolen is a bit ironic considering what the big tech companies have been doing for years.
OpenClaw is just demonstrating things we have know for years and never wanted to talk about. More than help the infrastructure runs on trust me bro security

Glad to hear it, there was a lot of changes to the imports in v5 which LLMs always struggle with

I cloned this locally for fun. setup the applesauce MCPin opencode. then told Claude to make a plan to rebuild the nostr extension using applesauce.
It read understood nostr, read lots of applesauce docs and examples. and produced a 100% accurate plan. Then it started coding and completely messaged everything up...

Built a nip-17 personal notes example in applesauce and found a bug with sending gift wraps. update the applesauce-actions package to 5.1.1 if your using it to send nip-17 DMs
