Proof Bundle Wire Format
The self-describing JSON and CBOR wire format of a Truestamp proof bundle, the named type registry, the subject with its claims, metadata and witnesses, block maps that carry their own metadata, the block path, external commitments, the signing key event, and why nothing opaque travels.
Proof Claims by Availability
Claims matrix for a Truestamp item proof, which of eight claims (bytes existed, unchanged, both submission-window edges, signature, key binding, ledger position, entropy freshness) hold from the bundle alone, from public chains and sources, from a pinned keyring, from the ledger, or never.
The Proof Lifecycle
How a Truestamp proof comes to exist and strengthens over time as an item is submitted against a set of witnesses, committed into a block via item commitment, and that block is committed to Stellar and Bitcoin via block commitment.
Verify a Proof
Step-by-step guide to verifying a Truestamp proof bundle offline by recomputing the leaf hash with domain separation, walking the Merkle inclusion path to the block root, rehashing each carried witness, and walking the epoch proof to the root recorded on Stellar or Bitcoin.
