# Blockstream: Bitcoin Can Add New Signature Schemes to Counter Quantum Threats

Blockstream said Bitcoin could add new signature schemes to address future quantum computing threats, with its research team evaluating lattice-based alternatives. After comparing Dilithium, Falcon and Hawk, the team identified Falcon-1024 as its preferred lattice-based candidate, citing its balance of compactness, verification speed and mature security assumptions. Deployment hurdles remain, including unfinished standardization, hardware wallet memory requirements and the lack of a workable public-key derivation scheme. The researchers emphasized that hash-based signatures remain the more conservative near-term option for Bitcoin, with hybrid deployment a potential future approach.
