Exploring CRDT Lexicons

I’ve (alongside many others I’m sure) been working on CRDT work with atproto, and I think we’ll need to come up with some standard for how to represent CRDT data as lexicons. @chris.pardy.family has written a leaflet exploring what such a record could look like and is looking for feedback and thoughts: CRDT's on ATProto I think it’s a good start. It doesn’t tie us to any particular CRDT, though it doesn’t guarantee interop between different CRDT types, which seems fine to me. I’m thinking may...

Homomorphically Encrypting CRDTs | jakelazaroff.com

Homomorphic encryption allows a computer to run programs on encrypted data. Learn how homomorphic encryption works through interactive examples, build a homomorphically encrypted CRDT and see whether it has promise for local-first software.

Proposal for a CRDTs on At Proto Working Group

There’s been some work done on using the PDS / At Proto as a to store and transmit CRDT operations. There is a general feeling that if we can figure out the right approach for this it will enable a number of new experiences on At Proto, specifically a collaborative editing approach that is localfirst. We hope that as a working group we can come up with some of the following: A set of best practices and recommendations that apps can adopt to enable collaborative, localfirst, editing via crdts ...

Substrates conference series - Substrates 2026

An increasing number of researchers see their work as interactive authoring tools or software substrates for interactive computational media. By talking about “authoring tools”, we remove the divide between programmers and users; “software substrates” let us look beyond conventional programming languages and systems; and “interactive computational media” promises a more malleable and adaptable notion of tools for thought we are striving for. This workshop aims to bring together a wide range of perspectives on these matters.
