Google just set a deadline. Quantum computers could break Bitcoin's encryption by 2029. Are blockchains ready?

Google and Oratomic published quantum computing research on the same day, and together they redraw the timeline for when blockchains need to be post-quantum secure. Google's paper, co-authored by Ethereum Foundation researcher Justin Drake and Stanford cryptographer Dan Boneh, estimates 2029 for breaking the elliptic curve cryptography that protects Bitcoin and Ethereum. Oratomic's findings are sharper: utility-scale quantum computers may need only 10,000 qubits, not the millions previously assumed, and the company already has 6,000 in the lab. With 6.7 million BTC in vulnerable addresses and a newly identified 9-minute attack window on unspent Bitcoin transactions, the question is no longer whether blockchains need to migrate. It's whether they can do it fast enough.
