Migrating Bitcoin to post-quantum security standards could take between five and ten years due to the network’s decentralised structure, according to crypto executive Jameson Lopp.
Lopp said Bitcoin differs fundamentally from centralised software systems because protocol changes require broad consensus rather than executive decisions.
He explained that upgrading cryptographic standards would involve not only technical changes but also a complex and coordinated migration of user funds.
Quantum computers won't break Bitcoin in the near future. We'll keep observing their evolution. Yet, making thoughtful changes to the protocol and an unprecedented migration of funds could easily take 5 to 10 years. We should hope for the best, but prepare for the worst.
Lopp said.
Lopp agreed with Blockstream chief executive Adam Back that quantum computing does not pose an immediate threat to Bitcoin’s security.
He noted that Bitcoin’s decentralised governance model makes rapid upgrades far more challenging than in traditional technology companies.
The discussion has reignited debate within the Bitcoin community over how urgently quantum-resistant solutions should be pursued.
