A stamped record becomes a leaf in the public transparency log at log.markovianprotocol.com, hashed as RFC 8785 canonical JSON under SHA-256, and the log's Merkle structure produces a root. Markovian submits that root to the public OTS calendars, which batch it into their own Merkle tree and write a single root to Bitcoin. The returned proof links the Markovian root through that tree to a Bitcoin block. Hashes are sent, never the data.
An OpenTimestamps proof establishes that data existed before a Bitcoin block time. It commits to a hash and nothing more. It makes no claim about whether the data is correct, which is exactly the Markovian claim. Provenance, not truth, holds on both layers.
The OTS proof is a second, independent anchor sitting beside the witnessed transparency log record. The two are adversary-disjoint: an OTS proof can be checked against Bitcoin L1 with stock tooling even if Markovian is offline.
The record below is a real COMMIT root submitted to all four public OTS calendars. The .ots downloads straight from the public verifier and checks with the unmodified ots client. The Bitcoin attestation attaches at the next calendar aggregation block; the proof upgrades automatically.
OpenTimestamps already does Bitcoin timestamping for free, accountless, with a decade of trust behind it. Competing with it would be a losing fight. Consuming it borrows Bitcoin's neutrality and that established trust, and lets Markovian add what OTS does not carry: the canonical markovian-provenance/v1 record, inclusion in a transparency log cosigned hourly by seven independent witnesses, and native interop with the other doors, W3C VC, A2A, MCP, ERC-8004, and C2PA.
The same record, two independent checks: the witnessed transparency log for the structured record and the doors, OpenTimestamps for a stock-verifiable Bitcoin proof.
Download the .ots and run the unmodified OpenTimestamps client against Bitcoin. The public verifier returns the provenance record behind the same root, with no account and no dependency on this site.
