6.6 Security 研究员用量子计算机破解15位椭圆曲线密钥获1 BTC奖励，凸显加密货币面临的量子风险日益增加。
独立研究员Giancarlo Lelli利用公开可用的量子硬件，成功破解了一个15位椭圆曲线密钥，并因此获得了Project Eleven颁发的1 BTC赏金。这一成就被认为是迄今为止最大规模的公开量子攻击椭圆曲线密码学案例。 此次突破比此前的公开演示规模大512倍，显示出量子攻击技术的快速进展。然而，与现实世界加密系统（如比特币使用的256位椭圆曲线密钥）相比，仍存在巨大差距。Project Eleven强调，虽然15位密钥远小于实际加密钱包所用密钥，但此次演示表明量子威胁正逐步逼近现实。 目前，约有690万个比特币存放在区块链上公钥可见的钱包中。如果量子计算机能力进一步提升，未来这些资产可能面临安全隐患。最新研究显示，破解256位椭圆曲线密码学或许只需不到50万个物理量子比特，这加剧了业界对比特币及其他主流区块链后量子安全措施的关注。
