PANews 5月22日消息,据Decrypt报道,Glassnode发布的研究显示,近三分之一的流通比特币已暴露公钥,理论上易受未来量子计算机攻击。具体而言,约604万枚比特币价值超4690亿美元存在量子风险。其中,约192万枚属于结构性暴露,源于早期“支付至公钥”地址、多重签名结构和Taproot输出等默认暴露公钥的脚本格式。约412万枚属于操作性暴露,源于地址复用行为。在操作性暴露的比特币中,交易所相关的约有166万枚,占总供应量的8.3%,占所有操作性暴露比特币的约40%。从各大交易所的持仓来看,Coinbase仅5%的比特币暴露于量子风险,而币安和Bitfinex的暴露比例分别高达85%和100%。Glassnode表示,该结果不应被解读为特定公司的风险排名或偿付能力信号。
