Timestamp anchoring (OTS)

A tree head only proves ordering relative to other entries. To prove when it existed, Confium anchors heads to the Bitcoin blockchain using the OpenTimestamps format: an OTS proof commits to the head hash, and Bitcoin’s proof-of-work supplies an attested time bound.

confium-transparency builds and verifies OTS proofs. Anchor cadence is your call: hourly anchoring is a common default; the proof size and verification cost do not depend on cadence.
