Tools: markovian_notarize markovian_stamp markovian_verify markovian_trace
markovian_notarize | Notarize any file or hash into a public transparency log cosigned by 7 witnesses from 6 operators and anchored to Bitcoin. Hash-only: pass a sha256 hex string, or with the local stdio server a file path (hashed on your machine; the file never leaves it) — only 32 bytes reach the log. Returns a receipt with the leaf index, inclusion-proof URL, an offline c2sp.org/tlog-proof bundle URL, and the witn params: path, sha256 |
markovian_stamp | Commit any data (an AI output, a decision, a record) into a public, witnessed transparency log and get back a verifiable, tamper-evident provenance stamp (canonical markovian-provenance/v1). It proves the data existed and was committed at this time; it does NOT assert the data is correct (provenance, not truth). No wallet, account, or funding is required, the first stamp just works, and only the S params: data*, wallet, label, derived_from |
markovian_verify | Look up a Markovian stamp by its merkle_root against the public verifier, with no key or account. verified:true means the stamp record exists and the response echoes its committed data_hash — recompute your content's SHA-256 and compare it to that data_hash yourself to confirm the content is unaltered. An unknown merkle_root returns verified:false. The trust-nobody path is the stamp's witnessed tr params: merkle_root* |
markovian_trace | Walk and verify a stamp's full provenance lineage by merkle_root. Use this when a stamp was created with derived_from links, to map what an output was built from. Returns a MAP of the graph (not a yes/no verdict): each node carries hash_binds and anchored, each edge carries edge_verified, and `valid` is true only if every node and edge checks out. A node whose payload was never published is an unr params: merkle_root* |
