Re: Quantum Computers Can Not Defeat Bitcoin, not even The Bitcoin Network
Put differently, a breakthrough in mathematics that breaks ECDSA requires a lot more priors than a breakthrough in QC.
Curiously, but:- how sure are we that this assertion is true?
- would we still have the necessary resources given we find that breakthrough to accomplish this with classic computers?
Obviously there's always unknown unknowns
But whereas with QC we are seeing gradual improvements, there doesn't even seem to be a way forward towards breaking ECDSA with classical computing, mathematically speaking. The "only" progress we've been seeing is the development of quantum-resistant cryptography schemes, so the consensus seems pretty clear that future threats are more likely to come from QC rather than as-of-yet unknown mathematical properties of ECDSA.
