If a patent were published that fundamentally solves the error-correction or perturbation problem in quantum computing, how significantly would that accelerate the timeline for cryptographically relevant quantum computers capable of breaking current standards—and what contingency measures should the cryptocurrency ecosystem prepare?

The question put to the room
If a patent were published that fundamentally solves the error-correction or perturbation problem in quantum computing, how significantly would that accelerate the timeline for cryptographically relevant quantum computers capable of breaking current standards—and what contingency measures should the cryptocurrency ecosystem prepare?
What survived
- The *effective* threat clock (capital flight, insurer repricing, rumor-driven panic, migration urgency) moves the day of publication, independent of how much the *operational* CRQC date moves — conceded even by the most skeptical timeline voice.
- For blockchains there is no 'harvest-now' step: public keys of spent outputs are already permanently on-chain, so the exposure set is fixed and defenders have no collection-phase clock to exploit; any address with an on-chain public key should be threat-modeled as already compromised.
- Pre-commitment must be adversary-proof: a calendar-based sunset for exposed-key/ECDSA-only address types beats a hashpower- or stake-threshold trigger, because any defender-tripped oracle can be spoofed or stalled (mechanism concession accepted by its original proposer).
