ContentLedger verification

Verify ledger record

This page recalculates the stored origin-evidence manifest digest, checks its canonical serialization, and independently reviews its archive, version-chain, timestamp-proof, and digital-signature references.

Verification results

Manifest digest

Valid

The SHA-256 digest was recalculated from the downloaded manifest bytes.

Canonical JSON

Valid

The manifest matches the deterministic ContentLedger RFC 8785 serialization profile.

Archive snapshot

Verified

The associated Wayback URL passed the plugin’s HTTP availability check.

Version chain

Valid

Any previous-manifest digest resolves to an earlier sealed record in this ledger.

Current content

Not available

Legacy records do not receive retroactive content-digest claims.

OpenTimestamps proofs

Alice via OpenTimestamps A Pool

Bitcoin attestation present

The proof contains a Bitcoin block-header attestation and is ready for independent verification with an OpenTimestamps client and Bitcoin node.

“Bitcoin attestation present” describes proof contents; this website does not claim that it independently validated the Bitcoin chain. Use the official client with a trusted Bitcoin node for that final check.

Site digital signature

Ed25519 compact JWS

Valid and currently authorized

The JWS signature is cryptographically valid for this manifest digest, and its public key is currently authorized by the site's did:web document.

Verification method

A valid signature associates the manifest digest with the displayed site-controlled key. It does not independently establish legal ownership, original authorship, or first publication.

Independent digest check

Download the canonical manifest without modifying it and calculate its SHA-256 digest with a local tool. The result must equal the manifest digest printed above.

sha256sum wp-contentledger-56764cf1-28e6-43a4-b9dd-2d5a5703b396.json

After installing the official OpenTimestamps client, independently verify a downloaded proof against the manifest digest:

ots verify -d d626d4c12b6ac1f75310cd42d19e170361aeee9245ec43b40d317cfd902e7c79 wp-contentledger-56764cf1-28e6-43a4-b9dd-2d5a5703b396-PROOF-ID.ots

The signature is an RFC 7515 compact JWS using the fully specified RFC 9864 Ed25519 algorithm and an RFC 8037 public JWK. An independent verifier should validate the JWS, confirm its manifestDigest claim equals the SHA-256 above, and resolve the kid against the published did:web document.
