CRDTs in Kotlin Multiplatform: Replacing Complex Sync Backends

Short summary

This tutorial demonstrates how to implement Conflict-Free Replicated Data Types (CRDTs) in Kotlin Multiplatform, eliminating server-side sync logic with dumb blob storage. The author compares practical CRDT types (LWW-Register, OR-Set) and sync strategies (state-based vs. operation-based) with code examples and architectural patterns. Result: offline-first apps that converge state automatically and scale with storage costs instead of backend complexity.

• •CRDTs enable conflict-free state synchronization across devices without a coordinating server
• •State-based CRDTs work well on mobile: idempotent merges tolerate unreliable networks without additional infrastructure
• •Replace your sync backend with authenticated blob storage; conflict resolution is built into the CRDT data structure
