A public, append-only transparency log. Records go in; nothing is ever edited or removed. Seven independent witnesses cosign the log's published heads, and its history is timestamped into Bitcoin hourly. Anyone can verify a record without trusting the operator.

Free, no account, hash-only — the log stores 32 bytes, you keep the file. The receipt carries the leaf index, inclusion-proof URL, SCITT receipt, and offline proof bundle. Or drop a file in the browser (hashed locally, never uploaded). Agents: MCP server at https://api.markovianprotocol.com/mcp/ (tools: notarize, stamp, verify, trace).
4-of-7 quorum, unrelated operators, keys pinned from each operator's own page. Cosignatures attest the history was never rewritten, not that any record is true. Machine-readable: /policy · human version: witness-policy.
Markovian operates a public witness that cosigns other transparency logs: witness.markovianprotocol.com. Other operators can have their checkpoints cosigned free: get witnessed.
