    Bitcoin post-quantum signatures: Blockstream backs Falcon

    Falcon emerges as the leading lattice option for Bitcoin Blockstream Research has published a detailed evaluation of lattice-based signatures that could one day help protect Bitcoin transactions against quantum attacks. The report compares Dilithium, Falcon and Hawk across on-chain size...

    Hardware Wallets Show Post-Quantum Signatures Are Feasible

    Existing Wallet Chips Meet a Quantum-Signature Test Blockstream says benchmark implementations of several hash-based post-quantum signature schemes ran on four widely used hardware wallet families. The result does not settle the whole quantum-migration problem for Bitcoin, but it challenges the...

    SHRINCS parameters cut Bitcoin quantum fallback signatures

    Blockstream narrows a post-quantum signature trade-off Blockstream Research says it swept 25,935 parameter candidates for SHRINCS, a hash-based post-quantum signature proposal aimed at Bitcoin. The work focuses on the stateless fallback path, where the team reports a signature around 5.7 KB...
