Archive snapshot
VerifiedThe associated Wayback URL passed the plugin’s HTTP availability check.
Version chain
ValidAny previous-manifest digest resolves to an earlier sealed record in this ledger.
Current content
Not availableLegacy records do not receive retroactive content-digest claims.
Site digital signature
Ed25519 compact JWS
Valid and currently authorizedThe JWS signature is cryptographically valid for this manifest digest, and its public key is currently authorized by the site's did:web document.
Verification methoddid:web:fireballnews.com#DjeLUjaodL9oX_rPJwua3boSmmsPTNx_6aEgA19HaPk
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-bdc222b7-259b-4d31-b0d0-95e2a02602dc.jsonAfter installing the official OpenTimestamps client, independently verify a downloaded proof against the manifest digest:
ots verify -d 0d51629938a1580c9fcda5a66b8039ed88929f6a092b545dfb9a57adf3dea89e wp-contentledger-bdc222b7-259b-4d31-b0d0-95e2a02602dc-PROOF-ID.otsThe 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.
