币界网报道：A recent breakthrough in quantum computing poses potential risks to Bitcoin's encryption security. Researchers have developed a method to significantly reduce the number of qubits required to break elliptic curve cryptography, which underpins Bitcoin's security. The new technique could theoretically crack Bitcoin's encryption with just 20 million qubits - a substantial improvement over previous estimates of 1 billion qubits. While current quantum computers only operate with hundreds of qubits, this advancement highlights the accelerating pace of quantum capabilities. Experts warn that within 10-15 years, quantum computers might reach the threshold to threaten blockchain security. The crypto community is urged to consider post-quantum cryptographic solutions, with some projects already exploring quantum-resistant algorithms. This development underscores the need for proactive measures to future-proof cryptocurrency security against emerging quantum threats.
