The Bitcoin (BTC) network now faces the largest quantum threat after a researcher cracked a 15-bit elliptic curve cryptography (ECC) key on a publicly accessible quantum computer.
On April 24, Project Eleven, a quantum computing research organization, awarded 1 BTC to independent researcher Giancarlo Lelli after he successfully derived a private key from its public key across a search space of 32,767 possible combinations. Lelli used cloud-based quantum hardware available to the general public to crack the 15-bit ECC.
The previous public demonstration of such an attack class was a 6-bit break, achieved in September 2025 by Steve Tippeconnic. As such, the possibility of a quantum attack on Bitcoin surged 512-fold in 8 months.
“The resource requirements for this type of attack keep dropping, and the barrier to running it in practice is dropping with them,” Alex Pruden, CEO of Project Eleven, stated.
