BIP-361 would block sends to quantum-vulnerable Bitcoin addresses, sunset legacy signatures, and put early BTC wallets at risk of being frozen if holders do not migrate in time.
Lightning Labs CTO Olaoluwa Osuntokun and StarkWare researcher Avihu Levy unveiled new Bitcoin quantum wallet prototypes as BTC held near 72,255 and the Satoshi market stayed at 9%.
Google Quantum AI said future machines could break Bitcoin's secp256k1 cryptography with far fewer resources, reviving focus on Satoshi Nakamoto's 1 million BTC as Polymarket kept pricing a higher risk premium.
Bitcoin developers merge BIP-360 to introduce quantum-resistant addresses, aiming to protect vulnerable legacy fortunes like Satoshi Nakamoto's estimated 1 million BTC from future quantum computing threats.
