Key Takeaways:
Project Eleven awarded researcher Giancarlo Lelli 1 BTC ($78,000) for cracking a 15-bit ECC key on IBM quantum hardware on April 24. Bitcoin developers showed Lelli’s result replicates with random noise, signaling zero quantum advantage over classical methods. The gap from 15 bits to Bitcoin’s 256-bit secp256k1 remains a 2^241 engineering chasm, leaving BTC security intact for now. Project Eleven Hands Giancarlo Lelli 1 Btc for 15-Bit ECC Quantum Break, but Software Developers Call It Noise“Bottom line: This is incremental progress in a noisy, early field — not Q-Day. It highlights why we track resource reductions and why post-quantum migration planning matters for long-term security. Skepticism is healthy; moving goalposts isn’t. Happy to discuss the technical details or share the repo/judges’ feedback.”
