Bitcoin and Quantum Computing
Summary
Bitcoin and Quantum Computing discusses the existential threat posed by a cryptographically relevant quantum computer to Bitcoin’s security, the uncertainties around the timeline for post-quantum upgrades, and the tradeoffs involved in selecting PQ signature schemes and coordinating soft forks, wallet and exchange upgrades. It provides a framework for evaluating risk (A and B), highlights the need for community consensus and technical work, and calls for proactive research and collaboration among developers, researchers, and users.
