Blockstream Research tested post-quantum signature schemes on existing consumer hardware wallets. Four popular devices successfully executed hash-based signatures. $SLH-DSA (NIST standard) worst-case execution: ~2 minutes.
Market takeaway: Legacy hardware compatibility confirmed for quantum-resistant cryptography. No forced hardware refresh cycle for wallet manufacturers. Implementation risk lower than previously priced by infrastructure plays.
