Avihu Levy, CPO of Starkware, released Quantum Safe Bitcoin (QSB) — the first scheme to make Bitcoin transactions quantum-resistant without any protocol changes. GPU costs range $75–$150 per transaction, leveraging RIPEMD-160 hash preimage resistance against Shor's algorithm.
Lightning Labs CTO Olaoluwa Osuntokun has introduced a prototype that could help Bitcoin users recover funds if quantum threats force emergency changes to the network’s signature system.
Lightning Labs CTO Olaoluwa Osuntokun built a prototype enabling Bitcoin users to recover funds from wallets if quantum threats force network upgrades. Using zero-knowledge proofs, it generates proof in under 1 minute (1.7MB file), offering a scalable solution to prevent user lockouts during emergency upgrades.
A new Google Quantum AI paper shows breaking Bitcoin's ECDSA encryption may require far fewer qubits than previously estimated, enabling potential real-time private key derivation in about 9 minutes. Roughly 6.9 million BTC are vulnerable due to exposed public keys. Industry leaders urge migration to post-quantum cryptography by 2029.
Avihu Levy, Starkware's CPO, published QSB on April 9, 2026, enabling quantum-safe Bitcoin transactions using existing script rules at $75-150 per tx, no softfork needed.
The Bitcoin community is divided over BIP-361, which proposes freezing non-migrated coins to counter quantum threats. Critic Frederic Fosco warns this would destroy Bitcoin's monetary premium and digital gold status, advocating for opt-in tools like BIP-360 instead of mandatory confiscation.
Lightning Labs CTO Olaoluwa Osuntokun has developed a prototype to help Bitcoin users recover funds from vulnerable wallets in the event of a quantum computing attack. Using zero-knowledge proofs, the system allows ownership verification via seed phrase without exposing private keys. Tests show proof generation under one minute and file size of 1.7 MB, providing a scalable rescue mechanism.
