Project Eleven: Q-Day could hit by 2030, and Bitcoin's quantum migration may already be running out of time!

A 110-page report from Project Eleven warns that more than $3 trillion in digital assets secured by elliptic curve cryptography could become vulnerable to quantum attack within four to seven years. The firm's CEO Alex Pruden and CTO Conor Deegan place Q-Day — the moment a quantum computer can break widely used public-key cryptography using Shor's algorithm — as early as 2030 and no later than 2033.

The threat extends well beyond crypto. The same elliptic curve digital signatures protecting Bitcoin, Ether, and stablecoins also underpin banking systems, cloud infrastructure, authentication networks, and military communications. A sufficiently powerful quantum machine could derive private keys from public keys, allowing attackers to forge signatures and seize control of wallets and digital accounts at scale.

The migration problem is not technical — it is a coordination crisis. Large…
