It looks very similar to Evolu (https://github.com/evoluhq/evolu)

cr-sqlite https://github.com/vlcn-io/cr-sqlite :

> Convergent, Replicated SQLite. Multi-writer and CRDT support for SQLite

From "SQLedge: Replicate Postgres to SQLite on the Edge" (2023) https://news.ycombinator.com/item?id=37063238#37067980 :

>> In technical terms: cr-sqlite adds multi-master replication and partition tolerance to SQLite via conflict free replicated data types (CRDTs) and/or causally ordered event logs

this also looks promising: https://braid.org/ working with the IETF to standardize.

I helped coauthor some of the early drafts of Braid. Braid isn’t an attempt to make a local first, crdt based eventually consistent data store. It’s just a protocol.

Braid aims to make it easy for such systems, as they’re built, to be able to talk to each other.
