Cloudflare fast-tracks post-quantum roadmap to 2029 as researchers slash qubit requirements for breaking ECC 20-fold

1.7M BTC have permanently exposed public keys that can never be re-secured, Chaincode estimates 7 years for full post-quantum migration, and IBM targets fault-tolerant quantum by 2029 — the timeline doesn't close. Oratomic's neutral atom architecture slashing the physical-to-logical qubit ratio from ~1,000 to 3-4 is what made 10k qubits viable for breaking P-256, and Google disclosing their improved ECC algorithm via ZKP instead of publishing it is exactly the kind of move you make when the results are too dangerous to share openly. Every chain running ECDSA should be treating PQ key rotation as a top-3 priority right now.
