Circle warns the quantum gap is closing as the estimated attack cost for ECDSA falls 65% in under a decade, putting exposed blockchain keys at risk

Circle has published a technical piece arguing that the gap between current quantum computing capability and the cryptography securing blockchain signatures is narrowing, though quantum computers do not yet pose an active threat. The article examines why the threshold for breaking ECDSA keeps falling, why wallet and chain infrastructure will need to change, and how Circle is preparing for post-quantum signatures. The headline's figure of a 65% drop in estimated ECDSA attack cost over under a decade is not elaborated in the body text.
