Bitcoin Q&A: Is Quantum Computing a Threat?

- Advertisement -

Is quantum computing a threat to Bitcoin? How can Bitcoin become more secure against a quantum computing attack? Will this upgrade require moving coins to new addresses? Will it be implemented as a soft or hard fork? What happens to coins controlled by lost keys?

CORRECTION: Apologies for the confusion – regarding the question of whether Satoshi’s (suspected) coins would be vulnerable to a quantum computing attack on ECDSA, the correct answer is in the first clip at 3:05. While what I initially say at 6:10 is true, that Satoshi did not spend their coins, those coinbase transactions still used pay-to-public-key (P2PK) instead of pay-to-public-key-hash (P2PKH), which means the public keys are already exposed.

3:31 Satoshi’s one million coins and quantum computing. Does quantum computing mean that, at some point, all lost coins could be reclaimed because they can’t be moved to an upgraded address?
5:13 Quantum computing attacks will most likely affect the digital signature algorithm first
