By Khwaish Manwani A Bitcoin (BTC) transaction using Starkware researcher Avihu Levy’s quantum-safe Bitcoin QSB method has been confirmed on the Bitcoin mainnet. This marks the first reported mainnet demonstration of the experimental construction. The transaction was created to safeguard BTC from future attacks involving powerful quantum computers without needing a soft fork or changes […]
