Blockstream Proposes Post-Quantum Bitcoin Signature SHRINCS

This proposal signals a proactive shift in Bitcoin's security discourse, moving from theoretical quantum risk to concrete engineering solutions. The emphasis on preserving transaction throughput suggests scalability and quantum resistance are being treated as complementary, not competing, priorities. The open question is whether such a signature scheme can gain community consensus and be integrated without disrupting existing network assumptions, a process historically fraught with technical and political friction.
