Civic Attest

Civic Attest is documented as cryptographic infrastructure for origin authenticity and public transparency, aimed at government and public-institution use.

What Civic Attest is

A Go-based system built around Ed25519 signing, a Merkle-tree public ledger, and RFC 3161 timestamp anchoring — designed so a signed communication's origin and byte-level integrity can be independently verified, offline if needed.

Properties stated by the repository

  • Origin authenticity (Ed25519 non-repudiation)
  • Byte-level integrity (SHA-256/SHA-3-512/BLAKE3)
  • Append-only public transparency ledger
  • Formal trustee-based key ceremonies

Limitations stated by the repository

  • Does not validate truthfulness of content
  • Cannot detect coercion or duress
  • Does not validate semantic meaning or context

Status, limitations, and proof trail

Documented Architecture and claimed-property boundary transcribed from the README.

The cryptographic implementation was not independently audited by this portal.
