The Problem With Auth Logs
Every authentication system keeps logs. But logs are mutable — an attacker who compromises your auth server can rewrite history.
SHA3-256 Chaining + Bitcoin Anchoring
Auth1 chains every auth event with SHA3-256. Each event includes the hash of the previous event, creating an append-only ledger.
Every 60 seconds, the chain head for each tenant is anchored to Bitcoin via H33-74 — distilled into a fixed 74-byte attestation covering three post-quantum signature families (ML-DSA, FALCON, SPHINCS+).
Why 74 Bytes Matters
Post-quantum signatures are huge — Dilithium alone is 2,420 bytes. FALCON is 666 bytes. SPHINCS+ is 7,856 bytes. H33-74 distills all three into 74 bytes — the same 74 bytes regardless of key size, data size, or which family is used.
Auth1 serves 20+ tenants — each with independent chains, independent API keys, independent branding.
Auth1 is live. SMS OTP, magic links, social login, session management — all PQ-anchored.
Introducing H33-74. 74 bytes. Any computation. Post-quantum attested. Forever.
