Deterministic Clock Sync in Swarms
Coordinating multi-agent sequences.
Problem
In a swarm of autonomous agents evaluating complex policies simultaneously, clock drift between executing nodes can invalidate time-bound cryptographic receipts or cause replay attacks in causal chains.
Approach
We enforce a strict logical clock (Lamport timestamps or Hybrid Logical Clocks) alongside wall-clock time within the receipt chain. When agents interact, they synchronize their logical vector clocks. A receipt evaluated at logical time T cannot reference a prevHash formed at T+1.
Invariants
receipt[n].logical_time > receipt[n-1].logical_time- A2A interactions must exchange logical clocks.
