Attacking bitcoin mining with a quantum computer would require the energy of a star, academics say

Academics have published papers concluding that attacking the bitcoin blockchain with a quantum computer is energetically infeasible, requiring the energy output of a star, and that previous quantum factoring breakthroughs can be replicated with outdated hardware, mitigating quantum computing risks to bitcoin's security. This research alleviates concerns about the potential vulnerability of bitcoin to quantum attacks, which could have led to a loss of investor confidence and a subsequent price decline. The removal of this risk is likely to have a positive impact on bitcoin's price and the broader cryptocurrency market.
