Liquid Network

Consensus: Quantum-Aware
Why this rating. Judgment call: Blockstream states that Liquid's block-signing protocol and peg remain classical and that it is working on quantum-resistant replacements. No code for these parts is published.
Transactions: Quantum-Aware
Why this rating. Judgment call: Blockstream broadcast SHRINCS-signed spends through a Simplicity contract on mainnet in March 2026. This is an application-layer contract, like Ethereum smart accounts; the protocol and wallets still sign with ECDSA and Schnorr.
Algorithms: SHRINCS
