ECHO-VERIFY specification

ECHO-VERIFY 1.0 is a specification designed as the C³ Self-Verification Standard. It organizes the lifecycle of issuing, revoking, replacing, and history-tracking verification identifiers, and defines the structure connecting the public surface (Verified Web) and the verification surface (Verify ID). Self-verification refers not to dependence on an external authority, but to being verifiable based on published specifications, versions, and verification paths. It does not mean quality assurance, investment return, exclusive rights, or specification-deciding authority.

ECHO-VERIFY defines the following structures.

• Issuing verification identifiers: generating a new Verify ID and recording the initial version.
• Revocation management: the revocation conditions of an identifier and public management of the revoked state.
• Replacement: migration from an old version to a new version and retention of history.
• History tracking: the structure for tracing the lineage of versions.
• Public-surface connection: the connection conditions with Verified Web.

"Self-verification" in ECHO-VERIFY refers to a state in which a verifier can verify independently — without going through a central institution — based on the published specification, version information, and verification paths.

This does not mean unilaterally asserting truth; it means the verification path exists on the public surface.

ECHO-VERIFY is a specification placed on the public-rail side of Two-Rail.

The lifecycle of verification identifiers is managed on the public rail, and revocation, replacement, and history are organized in a form traceable from the public surface. Details of the non-public rail are delegated to the Two-Rail Kernel.

ECHO-VERIFY does not mean any of the following.

• A guarantee or confirmation of truth
• Quality assurance
• Investment return
• Exclusive rights
• Specification-deciding authority
• Completion of a conformance judgment on its own
