比特币的最新数据（比特币 ) 能源消耗、效率和可扩展性有助于揭露银行业，同时让世界上最大的加密货币焕然一新。
一份研究报告发表 IT 工程师、密码学家和顾问米歇尔·哈扎卡 (Michel Khazzaka) 计算得出，比特币支付比传统金融系统“效率高出百万倍”。此外，银行业“使用的能源是比特币的 56 倍”。
该报告汇集了近四年的研究，并提出了一种新的计算方法来估算比特币的工作量证明能源消耗。在接受采访时，Khazzaka 告诉 Cointelegraph：
“总的来说，比特币闪电网络和比特币确实是非常棒且非常有效的技术解决方案，值得大规模采用。这项发明足够出色、足够高效且功能强大，足以被广泛采用。”
Khazzaka 于 2021 年底创立了支付咨询公司 Valuechain，他提出了一种替代剑桥比特币电力消耗指数 (CBECI) 提供的能源估算的方法。该指数，经常被 Cointelegraph 引用 ，估计比特币每年消耗大约 122 TW/H。
考虑到比特币矿机的平均寿命以及新 IT 材料的创造速度，Khazzaka 建议比特币每年消耗 88.95 TWh，远低于剑桥的估计。
Khazzaka 是一名支付专家，他于 2003 年撰写了有关密码学的论文，并于 2011 年发现了比特币，他还将银行业置于显微镜下，以有效地比较这两种货币体系。 Khazzaka 告诉 Cointelegraph，他“确实低估了银行业的各个方面”，与批评者相反，他的报告“偏向于银行系统”。
尽管如此，考虑到货币创造、货币运输、实体银行基础设施能源消耗等因素，他得出的数字为 4,981 TWh。四舍五入后，“传统支付”部门每年消耗 5,000 TWh。因此，银行业使用的能源是比特币的 56 倍。
该报告检查了目前的交易效率，“在当前的块大小下，如果块被填充到其最大容量，ηmax = 5.7 × 比经典系统更好的能源效率。”然而，这并没有考虑到考虑闪电网络。 在采访中，Khazzaka 解释道：
“闪电将使比特币协议在不消耗更多能量的情况下进行更多交易。这就是魔法。”
该报告得出结论，比特币和闪电网络的结合使比特币的能源效率比传统支付系统高“1.94 亿”倍。
对于 Khazzaka，该报告直言“银行和支付行业需要采用区块链，甚至可能采用比特币。”虽然 Khazzaka 的结论可能会让喜欢加密空间的密码朋克和无政府资本主义者感到惊讶，但 Khazzaka 认为比特币实际上可以使银行业受益：
“如果他们有足够的勇气使用区块链技术，它将提高他们的效率和可扩展性。”
尽管比特币的能源使用经常受到批评， 对银行业的调查将成为许多人的好消息。
