In financial applications, data integrity is everything. But in collaborative environments, waiting for a central server to confirm every transaction (the 'request-response' cycle) creates unacceptable latency.
Enter CRDTs (Conflict-free Replicated Data Types)
FairShare utilizes CRDTs to allow every user to edit the ledger simultaneously without a central coordinator. This ensures that even if you're offline (e.g., in a mountain cabin or a basement bar), your changes will merge perfectly once you reconnect.
WebSocket Infusion
While CRDTs handle the 'what', WebSockets handle the 'when'. We maintain a persistent full-duplex connection to push updates to every participant's device in under 100ms. This 'Main Character' experience means you see your friend log a coffee before they've even put their phone away.
Distributed Truth
By moving away from a single-point-of-failure database model toward a distributed state, we ensure that the ledger is always available, always accurate, and always synchronized.
