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
@99097983…a9ef75d5 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:
