ARK Invest’s Lorenzo Valente is more optimistic Bitcoin will beat Q Day

ARK's digital assets research director says Bitcoin looks better positioned to adopt quantum defenses than it did a year ago Quantum computing has long been the boogeyman of Bitcoin security debates. One of ARK Invest’s top crypto researchers now sounds less worried about it. Lorenzo Valente, ARK’s Director of Research for Digital Assets, says he is more optimistic than he was a year ago that Bitcoin will deploy a quantum fix before “Q Day.” That is the hypothetical moment when a quantum machine becomes strong enough to crack the cryptography protecting Bitcoin addresses.
