Blockstream implements quantum-resistant signatures on Liquid sidechain

Blockstream Research has deployed a post-quantum secure signature scheme called SHRINCS on the Bitcoin Liquid sidechain, the company announced on its official blog. The scheme adds new security conditions using Simplicity, Blockstream's smart contract language, without altering the network's core rules. This allows users to protect their assets from future quantum computing attacks. The move follows a report from the Google Quantum AI team, which analyzed that Bitcoin could be vulnerable to quantum computing attacks sooner than previously expected.
