Stacks Labs completes first quantum-resistant sBTC transfer on mainnet

Stacks Labs said it completed the first sBTC transfer on the Stacks mainnet using quantum-resistant cryptography. The transaction used the hash-based Lamport One-Time Signature, and the company said it demonstrated that quantum-resistant signatures can be verified through the Clarity smart contract language without changing the existing protocol. Stacks Labs plans to review the applicability of other quantum-resistant signature algorithms and expand its research to Bitcoin layer one. It added that Stacks uses BTC as its final settlement base, while sBTC is backed by BTC on Bitcoin L1. The company said the research is intended to strengthen Stacks’ ability to respond to quantum attacks and contribute to a future transition to a quantum-resistant security framework for Bitcoin.
