Abstract
This document discloses, as enabling public prior art, an erasable-subject proof-of-authorship vault. The vault records who conceived what, when in a form that a third party can verify offline, that stays provable after the creator's identity has been erased, and that is honest on its face about the evidentiary strength of every timestamp it carries. The mechanism does not claim the underlying transaction-coupled single-writer append-only ledger — that primitive is treated here as previously disclosed prior art (referred to throughout as Disclosure A, the single-writer baseline). Instead, this publication claims, strictly above that baseline, the composition of four techniques: (1) a per-disclosure prevhash chain that makes the sequence of authorship events tamper-evident, not just each row; (2) an erasable subject — a destroyable per-subject key that crypto-shreds identity while the priority chain and its timestamps stay verifiable; (3) honesty-graded timestamp receipts whose anchored:false grade is recorded truthfully and hash-committed so it cannot be silently upgraded; and (4) a portable, zero-trust, offline proof package and verifier. The publication is intended to bar patent monopolies over these four techniques and their combination.
