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

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.

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-4987edfd-1bf8-4efe-80b9-55b4075bde4d.json

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

ots verify -d b67b1effb5287570afaf01bf8473b5db0ee8f26e4576dce3e1b078e612204799 wp-contentledger-4987edfd-1bf8-4efe-80b9-55b4075bde4d-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.
