The New Age of Authorship: Blockchain Timestamping Meets Google E-E-A-T

Site signatureSignature verified

This record’s cryptographic signature was checked against the site signing key in its supplied Website Identity evidence. Signing-time authorization remains indeterminate. This does not verify the author’s identity, ownership, or the truth of the content.

Review signature checks
Bitcoin timestampBlockchain verified

The OpenTimestamps proof links this record’s exact manifest fingerprint to a confirmed Bitcoin block. This establishes that the fingerprint existed by the block’s timestamp. It does not verify authorship, ownership, or the claimed publication date.

A signed public HTTPS challenge verified control of the source site during enrollment. This does not verify author identity, ownership, or continuing control.

Verified at enrollment

Native ContentLedger evidence

The record-scoped Bundle v3 passed the current portable verifier. Manifest bytes and source attribution match this certificate. Signing authorization remains a separate limitation.

Valid with limitations

Native record signature

Cryptographic signature result for the submitted record; this does not independently establish publisher or author identity.

Verified

Bitcoin timestamp

The complete proof binds this manifest to a Bitcoin block checked against the repository’s trusted mainnet node. Block time is not a verified publication date.
