The Simplicity signature verifier is the first building block in making Liquid fully quantum-resistant. As Liquid's technical provider, Blockstream (nprofile…g8xl), is leading research into quantum-resistant bridges, confidential transactions, and assets. More to share soon. 🌊

Users can now protect their Liquid Bitcoin and issued assets against future quantum computer attacks.

Blockstream Research has deployed post-quantum signature verification on the LiquidNetwork (nprofile…0cnd) using Simplicity - a first on a production Bitcoin sidechain.

Opt-in quantum protection, available today. No consensus changes required.



How it works: Simplicity smart contracts enable custom spending conditions on Liquid. Lock your coins to a contract that requires post-quantum signatures to spend.

There are now real transactions on Liquid mainnet using SHRINCS, our optimized hash-based signature scheme.

The verifier library is open source and available now for wallet developers to integrate:
