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.

“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

Cryptographic signature valid

The protected public key verifies the JWS and its claims bind this exact manifest digest and ledger entry.

Current did:web authorization: Not currently authorized
Signing-key controller relationship: Current controller in the verified lifecycle chain
Historical key record/status: Registered during migration; pre-registry authorization is not established
Claimed issuedAt consistency: Not independently established
Lifecycle history integrity: Valid append-only event chain

The JWS issuedAt value is a signed claim, not an independent timestamp. did:web exposes current state and cannot by itself prove which key was authorized at that claimed time.

Cryptographic validity, historical authorization evidence, authorization at a claimed signing time, and current declared-DID authorization are separate results. None independently establishes legal ownership, human identity, original authorship, first publication, or a trusted signing time.

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-84111bf2-5127-4824-8a02-cd6dc8578964.json

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

ots verify -d 8df7df3fc496d725c1362d79f4d239e6035b65b48d07bedaa9d4ded9519124be wp-contentledger-84111bf2-5127-4824-8a02-cd6dc8578964-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 identity resource declared by that signature: its did:web document or did:webvh JSONL log.
