Helsing open-sources dson, a Rust crate implementing a delta-state CRDT for JSON-like data, enabling robust synchronization in high-latency, low-bandwidth edge environments. By eliminating tombstones and optimizing for space efficiency, it offers a pragmatic solution for offline-first applications like collaborative tools. This approach balances the trade-offs between op-based and state-based CRDTs, empowering developers to build partition-tolerant systems.
