A research collaboration with AI agents has reduced the estimated quantum resources needed for a key cryptographic attack on Bitcoin and Ethereum by over half, tightening the timeline for when these blockchains must consider post-quantum signature migration.
This Wire brief sits within Fusion42's coverage of Quantum Computing, Crypto & Web3 and Cybersecurity.
◆ ◆ The Wire takeaway
Quantum advances have brought post-quantum threats closer, so you building security tools must accelerate post-quantum signature support or risk exposures in Bitcoin and Ethereum. The resource gap narrowing means your crypto risk planning deadlines just moved up.
