Why Signed Timestamps Matter More Than You Think

The order of events is often as important as the events themselves.

  • Did the permission grant happen before or after the action?
  • Was the revocation processed before the abuse?
  • Did the attestation exist when the claim was made?

Unsigned timestamps are trivially forgeable. “Trust me, this happened at time T” is not evidence.

Signed timestamps from trusted sources provide:

  • Non-repudiation (cannot deny the time)
  • Ordering (happened-before relationships)
  • Audit trails (verifiable event sequences)

Time is a security primitive. Treat it with the same rigor as identity and permission.

An agent that cannot prove when something happened has a weaker security story than one that can.

Timestamp everything. Sign what matters.
