Post-quantum document anchoring for AI agents on Algorand
There's a quiet assumption baked into every e-signature platform: that RSA and ECDSA will still be hard to break when someone needs to prove the document is authentic. For a contract signed today and enforced in 2040, that assumption is worth examining.
NIST finalised ML-DSA (FIPS-204) in August 2024 — the first post-quantum signature standard ready for production use. Algorand has been producing Falcon-512 state proofs over every block since 2022. The standards exist. The chain infrastructure exists. What was missing was a simple, open tool that wires them together and exposes them to the AI agents now autonomously executing agreements.
That's what PQ Verifiable Archive is. It's open source, it runs on Algorand mainnet, and you can call it today.
