While there has been recent progress in error correction and resource estimates, scaling the actual operations required for cryptographically relevant machines remains an unproven bottleneck. Cryptographically relevant quantum computers (CRQCs) are not a structural threat to bitcoin consensus or its monetary foundations (e.g. issuance schedule, supply cap, etc.). The main risk to bitcoin is targeted theft of coins with exposed public keys. A public key is the public half of a cryptographic key pair associated with a speci","default_branch":null,"files":null,"tree":[],"storefront":"/r/presidiobtc","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/presidiobtc/bitcoin-quantum/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
