Project Eleven's experiment used public cloud quantum hardware to crack elliptic curve encryption at 512 times previous scale. About 6.9M BTC (worth over $530 billion) sit in addresses with exposed public keys, pushing quantum risk from theory to hardware.
Project Eleven awarded 1 BTC to independent researcher Giancarlo Lelli for breaking a 15-bit elliptic curve key on publicly accessible quantum hardware, the largest public demonstration so far of this attack class.
A researcher broke a 15-bit ECC key using public quantum hardware, but experts note the gap to Bitcoin's 256-bit security remains enormous. However, Google's lowered resource estimates and 2029 migration deadlines signal a real future threat. The industry must prepare.
A recent quantum computer demonstration cracked a 15-bit ECC key, sparking fear. However, this is far from Bitcoin's 256-bit security. Google's resource estimates have dropped and migration deadlines are set for 2029, but real threats remain years away. This article provides an objective analysis of the current risk and future scenarios.
Researcher Giancarlo Lelli used a 70-qubit quantum computer to derive a 15-bit elliptic curve private key, but the feat remains far from threatening Bitcoin's 256-bit security. Google and Cloudflare target 2029 for post-quantum migration, highlighting accelerating risk. Market impact limited for now; watch governance and protocol upgrades.
A researcher used a 70-qubit quantum computer to derive a 15-bit ECC private key, triggering exaggerated headlines about Bitcoin's vulnerability. In reality, 15-bit vs 256-bit security remains an enormous gap, and no known quantum computer can break real Bitcoin wallets today.
A researcher used a 70-qubit quantum computer to crack a 15-bit elliptic curve key, far from Bitcoin's 256-bit security. Google and others set 2029 post-quantum migration targets, urging industry preparation.
Independent researcher Giancarlo Lelli cracked a 15-bit ECC key on public quantum hardware, winning Project Eleven's 1 BTC prize (~$78k). The 512x improvement from prior demos signals quantum threats are narrowing, though Bitcoin's 256-bit security remains unscathed for now.
