Sealed document fingerprints — public existence anchor (v1)
收藏官方服务：
资源简介：
SHA-256 fingerprints of sealed documents, published as a public existence proof at a fixed date. The bundle carries an RFC 3161 timestamp receipt (FreeTSA, granted 2026-09-26 18:02:06 GMT) and an OpenTimestamps proof for the Bitcoin calendar. It contains digests only — no question text, no method, no analysis — so it proves that the listed files existed unchanged at that date, and nothing about their correctness.
