EU financial watchdogs warn quantum computing poses imminent threat to blockchain encryption
Why now
Thesis: Encryption risk re-enters bitcoin's long-term security debate
Catalyst to watch: Further regulator warnings or quantum research milestones
Main risk: Uncertain timeline makes threat easy to dismiss
Why it matters
If quantum computers can break exposed public keys, legacy bitcoin addresses become a security liability, pressuring holders and developers to migrate.
Details
The warning brings renewed urgency to the debate over how bitcoin should deal with legacy addresses whose public keys are already exposed onchain.
