New Proposal Claims Quantum-Safe Bitcoin Without a Fork

AI-summarised brief · reviewed before publication

A new proposal for "quantum-safe" Bitcoin transactions has been introduced, allowing the network to defend against future quantum attacks without requiring a protocol change. The method, referred to as QSB, relies on hash functions and Lamport signatures to achieve roughly 118-bit second pre-image resistance. It operates within Bitcoin's existing scripting system, combining multiple cryptographic techniques into a layered transaction structure, and requires users to perform computational work off-chain to generate valid transactions.
