🔐 Q-Day Just Got Closer — And Someone Just Won 1 $BTC Proving It.
A researcher named Giancarlo Lelli just cracked a 15-bit elliptic curve cryptography (ECC) key on a regular cloud quantum computer — no government lab, no special hardware.
For that, #ProjectEleven awarded him 1 #BTC as part of their Q-Day Prize.
Why does this matter for crypto?
Bitcoin, Ethereum, and almost every major blockchain use ECC to secure wallets. Your private key is protected by a math problem called ECDLP — and Shor's Algorithm on a #quantum computer is designed to break it.
Right now, #bitcoin operates at 256-bit scale. Lelli broke 15 bits. Still a big gap — but here's the scary part:
•6 months ago, the record was 6 bits
•This result is a 512x jump
•Google's latest estimate says a full attack needs <500,000 qubits
•A Caltech/Oratomic paper says it could be done with as few as 10,000 qubits on neutral-atom hardware
The gap is no longer a physics problem. It's an engineering timeline.
What's at risk right now?
6.9 million BTC sit in wallets with exposed public keys on-chain. Those are directly vulnerable once quantum hardware scales up.
The bottom line:
Google committed to being quantum-secure by 2029. Blockchains haven't. The window to migrate to #PostQuantum cryptography is closing — and events like this are the proof of concept that moves it from theory to urgency.
