Kuantum sonrası kriptografi alanında faaliyet gösteren Project Eleven, kuantum bilgisayarların modern şifreleme sistemlerini kırabileceği Q Günü'nün 2030 gibi erken bir tarihte yaşanabileceğini öne sürdü. Şirkete göre, belirli koşullar altında 560 milyar dolardan fazla değere sahip yaklaşık 6,9 milyon Bitcoin kuantum riskiyle karşı karşıya kalabilir.
Giancarlo Lelli won one Bitcoin from Project Eleven's Q-Day Prize on Apr. 24 for deriving a 15-bit elliptic curve private key from its public key using publicly accessible quantum hardware — the largest demonstration of this attack class that could threaten Bitcoin and Ethereum. While a 15-bit key is nowhere near Bitcoin's 256-bit security, Google cut ECDLP-256 resource estimates 20-fold in March and set a 2029 migration deadline, with Cloudflare matching that target.
Project Eleven awarded 1 BTC to an Italian researcher after a public quantum computer breaks a 15-bit elliptic curve key, the largest public demonstration of its kind to date.
