Conflict-free Database over Virtual File System
This time we're going to cover a new implementation of persistent key value store, using Conflict-free Replicated Data Types (CRDTs) to enable multi-process writes. Moreover, this approach enables shift of replication protocol from custom made gossip…

Can Yrs fit my table?
In this blog post we'll design a collaborative 2D table structure using yrs - Rust port of popular yjs conflict-free replicated data types library for creating real-time, local-first apps. We'll also cover some optimizations…
Non-interleaving Linear Sequence (LSeq) CRDT
Today we're going to jump into LSeq - one of the famous text-editing conflict-free replicated data types we briefly introduced in the past blog posts. This time we're aiming for fixing one of the popular…
