StarkWare's Avihu Levy Proposes Quantum-Safe Bitcoin Transactions Without a Soft Fork
StarkWare's Chief Product Officer introduced Quantum Safe Bitcoin (QSB), a scheme that makes BTC transactions quantum-resistant using existing Bitcoin Script capabilities — no protocol upgrade needed.
Lightning Labs CTO Builds zk-STARK Prototype to Shield Bitcoin Wallets From Quantum Threats
Olaoluwa Osuntokun has released a working prototype of a zk-STARK-based tool that lets Bitcoin wallet owners prove ownership without exposing private keys, offering an escape route if emergency quantum-defense measures freeze existing signature schemes.
US Department of Energy Announces Plans to Build Quantum Computer Within Three Years
The US Department of Energy aims to develop a fault-tolerant quantum computer by 2028, marking a major strategic shift for the nation's largest physical science funder.
Google: Breaking Bitcoin Requires 20x Fewer Qubits Than Previously Estimated
Google researchers found that fewer than 500,000 physical qubits could be enough to crack Bitcoin and Ethereum's cryptographic defenses — a 20-fold reduction from prior estimates.
