Each node settles transactions locally, within its own reference frame. Bundles then sync asynchronously across the mesh — no global clock, no bottleneck.

Proof of Proximity uses time-of-flight cryptography to verify a transaction's physical origin. If the signal timing doesn't match the claimed location, it's rejected.

When a signal takes 22 minutes to reach Mars, a traditional blockchain doesn't slow down — it breaks. Entos treats latency as a given: transactions are final the moment they're signed.

Entos orders events by cause, not by clock. A transaction on Mars that leads to a settlement on Earth is valid by the causal chain between them — no shared timestamp required.

When nodes reconnect after a blackout — a 22-minute Mars silence or a cislunar handoff — their local DAGs merge into a single consistent state. No rollbacks, no conflicts, just causality doing the work.
