Google dự báo máy tính lượng tử có thể phá vỡ mã hóa hiện tại vào năm 2029, sớm hơn 6-15 năm so với dự đoán trước đây. Các công ty như Google và Cloudflare đang gấp rút triển khai mật mã hậu lượng tử để đối phó.
L'arrivée des ordinateurs quantiques, surnommée "Q-Day", pourrait rendre obsolète la cryptographie actuelle d'ici 2030-2050. Ces machines, capables de déchiffrer des codes complexes en secondes, posent des enjeux géopolitiques majeurs, poussant à l'adoption de cryptographies post-quantiques.
The US government announced a $2.013 billion investment in quantum computing, funding nine companies to accelerate the technology. This advancement poses a significant threat to Bitcoin's cryptographic security, potentially enabling the cracking of its encryption.
The U.S. government is investing over $2 billion in quantum computing companies, including a $1 billion initiative with IBM for a New York-based quantum wafer foundry. This move addresses growing concerns that future quantum computers could break current encryption methods.
By the time Bitcoin and other networks are ready to defend themselves, it may already be too late, according to a new analysis.
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.
Ripple announced a multi-stage plan to prepare the XRP Ledger for post-quantum cryptography with a 2028 target for full readiness, responding to Google Quantum AI research showing roughly 500,000 physical qubits may be enough to attack ECDLP-256 cryptography. The four-phase roadmap begins with contingency planning in 2026, followed by research and testing, controlled environments on Devnet, and a production transition involving a new XRPL amendment.
Experts warn quantum computers could someday forge Bitcoin’s digital signatures, allowing unauthorized transactions.
Here's which players are winning the race to transition to post-quantum crypto.
