Timestamp as a Service, not an Oracle
Summary: Replace centralized timestamp oracle with a bipartite client-server logical timestamp service whose servers do not communicate, providing timestamp availability unless a majority of servers fail. TaaS formalizes availability/monotonicity, proves correctness of a monotonic spacetime over clocks, and a prototype achieves TiDB-comparable performance and datacenter-level resilience.
