Report #103128

[architecture] How do I synchronize agent state across nodes without running a consensus protocol on every update?

Use Conflict-Free Replicated Data Types \(CRDTs\) for state that can be updated independently at each replica and merged later without coordination.

Journey Context:
CRDTs \(Shapiro et al. 2011\) exploit algebraic structure to guarantee that replicas converge to the same state once they have seen the same set of updates, with no consensus round required. Common types include G-Counters, PN-Counters, OR-Sets, LWW-Registers, and sequence CRDTs. They are ideal for counters, presence indicators, shopping carts, and collaborative document state. The tradeoff is that not all semantics can be expressed conflict-free; you must accept add-wins or remove-wins semantics and sometimes pay metadata overhead \(tombstones, unique tags, version vectors\). When you need strong ordering or invariants, fall back to consensus; when you can tolerate defined conflict semantics, CRDTs remove a huge coordination bottleneck.
