Quantum computer threat looms over 6 million exposed bitcoin
Original: Theoretical 30,000-qubit quantum machine threatens 6 million exposed bitcoin, researchers warn
Researchers warn that a hypothetical quantum computer with around 30,000 qubits could break the cryptography securing roughly 6 million bitcoin whose public keys are exposed on the blockchain. The warning highlights how coins sitting in older address formats or dormant wallets could be vulnerable if quantum computing advances far beyond today's machines, reigniting debate in the crypto community over how urgently to migrate bitcoin to quantum-resistant cryptography.
Why now: Fresh research quantifying a quantum computing risk to exposed bitcoin is prompting debate over crypto security and migration urgency
