Continuum Verifier
Continuum Verifier is an offline verifier for portable provenance records that processes self-contained evidence capsule files.
Continuum Verifier is an offline tool designed to verify portable provenance records contained within single self-contained files. It checks content fingerprints, signed record chains, Merkle inclusion proofs, issuer keys, public-witness anchors, and re-stamp trails without requiring an internet connection or access to the issuer system. The tool runs locally using Python with the cryptography library for Ed25519 verification. It produces verdicts such as verified, self-consistent, restamp needed, withheld, or failed based on strict checks. This reference implementation at version 0.1 suits developers and auditors who need to check data custody and integrity using transparent record files.
