First Triple-Fingerprint Multi-Layer Permanence Record Under the Reilly EternaMark (REM) Protocol

This document records and formally attests the first cryptographic permanence record produced by a live implementation of the Reilly EternaMark (REM) Protocol [DRAFT-REM] that simultaneously generates SHA-256 [RFC6234], SHA3-512 [FIPS202], and BLAKE3 [BLAKE3SPEC] fingerprints for a single submitted artifact, and anchors those fingerprints across six independent permanence layers: Bitcoin blockchain timestamping via OpenTimestamps [OTS], IPFS [IPFS] distributed storage via Pinata, Zenodo DOI registration [ZENODO], Internet Archive Wayback Machine submission [IA], a persistent SQLite database layer, and a resolvable REMID permanent identifier [DRAFT-REM]. This record constitutes what the author believes to be the first document in history to be simultaneously anchored with SHA-256, SHA3-512, and BLAKE3 under a single open IETF-documented protocol specification with a live running implementation. The SHA3-512 component of this record provides 256-bit post-quantum security against Grover's algorithm [GROVER], exceeding the NIST post-quantum security threshold [NISTPQC].
