Quantum Computers Unlikely to Threaten Bitcoin in the Near Term, Experts Say
Experts largely agree that quantum computers pose no immediate threat to Bitcoin's security, though timelines for potential risk vary widely.Summary
Experts, including Jameson Lopp of Casa and Adam Back of Blockstream, assert that quantum computers will not break Bitcoin in the near future, citing massive research and development hurdles remaining for useful-scale quantum machines. While some, like David Carvalho, warn of risks within 2 to 3 years, others point to timelines decades away. Charles Hoskinson also noted that while transitions to quantum-resistant cryptography are possible, they would incur significant efficiency costs. A major hurdle for Bitcoin is the difficulty of implementing quantum-proofing due to its decentralized nature; unlike centralized systems that can mandate updates, Bitcoin requires broad social consensus and voluntary user participation, meaning permanently lost or inactive wallets will remain vulnerable.
