Các nhà quản lý tài chính EU cảnh báo máy tính lượng tử có thể đe dọa bảo mật blockchain

The Huoxing Finance report states that the European Banking Authority (EBA), the European Insurance and Occupational Pensions Authority (EIOPA), and the European Securities and Markets Authority (ESMA) indicated in their joint risk update that advances in quantum computing could undermine the cryptographic systems securing blockchain transactions, communications, and databases. In March, Google Quantum AI researchers estimated that the number of physical qubits required to break the cryptographic technologies used by many cryptocurrencies may be about 20 times fewer than previously estimated. No computers capable of executing such attacks currently exist. In February, Bitcoin developers including Jameson Lopp proposed phasing out current signature schemes and restricting the use of unmigrated funds five years after proposal activation; this proposal has not yet been adopted. The Ethereum Foundation plans to make Ethereum’s execution, consensus, and data layers quantum-resistant by December 2029.
