Ark Invest says quantum computing is a long-term risk for bitcoin, not an imminent threat

Ark Invest, in a report co-authored with Unchained, concluded that quantum computing poses a long-term risk to Bitcoin security but is not an imminent threat. Current quantum systems lack the necessary capabilities to compromise Bitcoin's elliptic curve cryptography. The report suggests that if quantum capabilities advance sufficiently, the disruption would likely affect broader internet security first, prompting coordinated responses before reaching Bitcoin. Ark Invest estimates that about 35% of Bitcoin's supply resides in address types theoretically exposed to future quantum attacks, including lost coins and those easily migratable. However, the firm anticipates this progression unfolding over many years in distinct stages, providing the community ample time to upgrade the network with quantum-resistant cryptography and migrate vulnerable coins to safer addresses, noting that the necessary protection methods are already known.
