Quantum Computing Could Break Bitcoin-Like Encryption Far Easier Than Intially Thought, Google Researcher Says

A new research paper by Google Quantum AI researcher Craig Gidney shows that breaking widely used RSA encryption may require 20 times fewer quantum resources than previously believed.The finding did not specifically mention bitcoin BTC or other cryptocurrencies, but took aim at the encryption methods that form the technical backbone used to secure crypto wallets and, in some cases, transactions.RSA is a public-key encryption algorithm used to encrypt and decrypt data. It relies on two different but linked keys: a public key for encryption and a private key for decryption source: https://www.coindesk.com/tech/2025/05/27/quantum-computing-could-break-bitcoin-like-encryption-far-easier-than-intially-thought-google-researcher-says
