Europol has released two reports urging the crypto industry and policymakers to proactively address the threats posed by quantum computing. The reports state that crypto wallet keys are the main point of vulnerability, while the hash functions that ensure blockchain operations currently have basic quantum resistance. Research estimates that upgrading all Bitcoin transaction outputs to a quantum-resistant solution would require a total downtime of at least 76 days. Additionally, the reports note that there is currently no clear evidence of large-scale systematic use of 'steal now, decrypt later' attacks.
