Bitcoin quantum-resistant transaction test… network signature transition undecided

Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Blockstream co-founder Adam Back dismissed warnings that Bitcoin (BTC) faces collapse from quantum computing, pushing back on what he called alarmist fears after a draft for quantum-resistant transactions and signatures was published without changing the network's existing signature rules. The threat centers on Bitcoin's elliptic-curve ECDSA and Schnorr transaction signatures, which a sufficiently powerful quantum computer could attack using Shor's algorithm, though Blockstream says it is unknown when such a machine will arrive. The draft introduces post-quantum signature options but leaves Bitcoin's protocol-level signing rules untouched, meaning adoption remains optional and undecided. The debate matters because any eventual migration would touch wallet standards, address formats and the security assumptions underpinning the largest cryptocurrency. What to watch next is whether the draft advances toward a formal Bitcoin Improvement Proposal and how miners, node operators and wallet providers signal support for a network-wide signature transition.
