Bitcoin should prepare now, even if quantum is a 'lab experiment’: Adam Back

Back said the safest approach is to build optional upgrades that would allow Bitcoin to migrate to quantum-resistant cryptography once it's needed.

Blockstream CEO Adam Back, an early pioneer of the crypto movement, said Bitcoiners should be looking at building quantum-resistant solutions now, even if the threat is still decades away. 

“Quantum computing still has a lot to prove. Current systems are essentially lab experiments. I’ve followed the field for over 25 years, and progress has been incremental,” Back said at Paris Blockchain Week on Tuesday.

“That said, Bitcoin should prepare,” Back said, adding that the “safest approach” is to build optional upgrades that allow migration to quantum-resistant cryptography if needed.
