Europol warns that quantum computers will primarily threaten exposed cryptocurrency wallet private keys rather than blockchain integrity itself and urges a phased shift to post-quantum cryptography to protect wallets before powerful quantum computers emerge.

This Wire brief sits within Fusion42's coverage of Fintech.

You must start upgrading your crypto wallet security to quantum-resistant standards now or face irreversible asset loss. The window to lead the migration is limited before dormant but vulnerable wallets are targeted.
