OpenTimestamps
A Bitcoin timestamping protocol proposed by Peter Todd. It aggregates data hashes into a Merkle tree and anchors them to the Bitcoin blockchain, producing decentralized, independently verifiable proofs of existence at very low cost.
Timeline (last 90 days)
OpenTimestamps is a Bitcoin timestamping protocol proposed by Peter Todd that submits the SHA-256 hash of data to calendar servers, aggregates them into a Merkle tree, and writes it to the Bitcoin blockchain, providing an extremely low-cost, no-need-to-trust-a-single-server "not later than" proof of existence at a certain point in time.
The team introduced the 15th canonical tool, proof.notarize; by integrating OpenTimestamps into the MCP toolkit, autonomous agents can submit the SHA-256 hash of their internal state, and the engine aggregates it into a Merkle tree and anchors it to the Bitcoin base layer, returning an encrypted .ots receipt.
