The maximum quantum attack sounds frightening, but upon closer inspection, it's just a demonstration-level breakthrough with a 15-bit key.

Independent researcher Giancarlo Lelli derived a 15-bit elliptic curve key using a publicly accessible quantum computer, marking what Project Eleven called the "largest quantum attack" on elliptic curve cryptography to date, according to the startup. Project Eleven awarded Lelli a 1 BTC bounty,
