Maintaining sequential consistency without sacrificing availability is possible in unstable edge environments by embracing eventual consistency. Using Conflict‑Free Replicated Data Types (CRDTs) with a grow‑only set and Last‑Write‑Wins mutation rule, each edge node stores data locally with UUIDs and monotonic timestamps. When connectivity returns, records are merged via deterministic UPSERT, ensuring convergence without duplicates or regressions. This offline‑first architecture proves resilience: edge devices remain autonomous, and the system mathematically guarantees integrity across hundreds of nodes even during prolonged outages.
