you should never paste your secret key into a desktop client. #plaza lets you bring your key in with one terminal command.

#plaza is getting a built-in signer, #signet. anything that touches your key happens in signet's own process, never in the client. when you import a key you already have, the client never sees it. it goes straight into the signer. that's finally true, not just a slogan.

the signer's core, the part that guards your key and signs, is moving into my open nostr library. so any zig client can build on it, not just mine.

the whole idea: your key should feel like it lives somewhere safe and separate, even inside an app that's trying to be effortless. those two shouldn't fight. View quoted note →

gm nostr. small win today: proved #plaza can pop open a separate signer window on its own. sounds boring, but it's what lets your key stay in its own process.

building a client that feels instant is mostly about not doing work. not re-reading what has not changed. not building what is off screen. not fetching what is already on disk. most of my performance work is deleting things. #plaza View quoted note →

numbers from #plaza's feed while scrolling hard: about a twentieth of a millisecond to work out what to draw. the frame budget is 8 milliseconds. there is a lot of room in there. here's the first demo ever:

#plaza is a nostr client written in Zig that draws its own pixels. no browser inside it, no web view, no javascript. it opens fast, it scrolls smooth, and it stays out of your way.

opened #plaza and your notes are just there, instantly. it reads from your own machine first and talks to relays second. no spinner while a relay decides whether to answer you.

#plaza scrolls the same whether your feed holds 20 notes or 2000. it only ever builds the handful of cards actually on your screen. everything below the fold costs nothing until you get there.

been building a native desktop client on top of my zig-nostr library. calling it Plaza. local-first. no browser. still early, but it's already pulling live notes off a relay. nice to watch it come together.

jumble.social is in a league of its own.

gm. a small step toward bringing nostr into the zig ecosystem. zig-nostr is now listed in "Awesome Zig". still early, but the bridge between the two communities is taking shape.

back building on nostr after a long quiet stretch. currently working on: • zig-nostr: the native nostr protocol stack for Zig • local-first LMDB event storage • NIP-46 relay transport and remote signing • Signet: a native macOS signer with the key isolated in a daemon current status: pre-alpha, moving quickly. looking for native-client developers, Zig reviewers, and people willing to break it.

Signet design choice i'll defend: two processes. a headless daemon owns the key and the relay connections. the gui is just an approval queue over a loopback-only api. if the pretty half ever gets compromised, the half with the key does not care. View quoted note →

made a thing: Signet - a native remote signer for nostr. your key lives encrypted (NIP-49) inside a small daemon on your machine. apps request signatures over NIP-46, and every single request waits for an explicit approve/deny in a native macOS app. the key never enters the GUI, let alone a client. works over public relays, including ones behind NIP-42 auth.

benchmarked my zig-nostr store against nostrdb and rust-nostr and found my feed query ~90x slower than it should be. i collected every match, then sorted, then truncated. nostrdb walks its indexes newest-first and stops at the limit. adopted the approach, credited the teacher: 26ms → 0.28ms for a 20-author feed over 100k events. #devstr #zignostr

gm. favorite part of the zig-nostr library so far: a local-first event store on LMDB. zero-copy reads, events stay memory-mapped, modeled openly on nostrdb. the goal is feeds that render from disk in a blink while the network reconciles in the background. never the other way around.

been writing a lot of zig these days. it stays out of your way the way C does, but the build system is a real language you can think in. comptime still bends my brain a little. i like it.
