OpenTimestamps aims to be a standard format for blockchain timestamping.
attested.network — Proof of Payment for ATProtocol
An open specification for decentralized, cryptographically verifiable proof of payments.
Just a rumour of a bug is enough to find a security exploit these days
Thinking through how the conventional OSS security embargoes no longer buy us time, and what open source maintainers might do instead to respond
Permissioned Data Diary 2: Buckets - Daniel's Leaflets
The second in a series of posts building up a solution to permissioned data on atproto. We introduce buckets: a new protocol primitive for creating a shared social context.
ATProtocol Attestations: Cryptographic Signatures for the Decentralized Web - Nick's Blog
This post introduces the formal ATProtocol attestation specification, a framework for adding cryptographic signatures to ATProto records through two complementary patterns: inline attestations that embed signatures directly in records, and remote attestations that store proof in separate repository records. The specification prevents replay attacks through repository binding, uses CID-based content addressing for integrity, and provides the cryptographic foundation for verified credentials, trusted content, and authenticated interactions in the decentralized ATProtocol ecosystem.
Permissioned Data Diary 1: To Encrypt or Not to Encrypt - Daniel's Leaflets
The first in a series of posts about major design decisions along the way to a permissioned data protocol for atproto.
Willow - Home
Peer-to-peer protocols which scale up, down, and sideways. Sychronisable data storage, fine-grained access control, private and efficient synchronisation, and secure data delivery by any means possible.
Permissioned Data Shapes: Self-Only Bookmarks - Nick's Blog
A self-only space is the smallest shape permissioned data can take: one authority, one member, one repo, and private bookmarks that share a record shape and a write path with public ones.
timelocked secrets
Encrypt messages that can only be decrypted after a specific time. Powered by drand timelock encryption and stored on your atproto PDS.
Atelier — Your work, in your hands
A transparent foundation preview for an open productivity suite spanning notes, mail, calendars, and tasks, powered by ATProto.
From ZK-first to AT Protocol — our path to DDS | Agora Citizen Network
We've been building Agora — a platform for public deliberation using Polis-style clustering — for a while now. Along the way, we've written about what we think about Nostr, AT Protocol, Polis, Community Notes, and protocol interoperability. Those posts are somewhat outdated now. This one describes w...
archive.today is directing a DDOS attack against my blog
Around January 11, 2026, archive.today (aka archive.is, archive.md, etc) started using its users as proxies to conduct a distributed denial of service (DDOS) attack against Gyrovague, my personal b…
Encrypted Spaces — Research preview
An architecture for collaborative applications where data is encrypted and operations are cryptographically verifiable.
Slingshot: atproto edge record cache
API Documentation for Slingshot, a firehose-listening atproto edge record and identity cache.
In 2026, @bsky.app is focused on what’s next for open social: bringing together users for conversations around live events, creator and platform monetization, and private state, giving users truly private data while preserving ownership and portability at the protocol level.
