论文摘要
比特币网络正在燃烧大量的采矿能量。在本文中，我们估计自2010年以来十年来全球能源成本的下限，考虑到石油成本的变化，哈希技术和哈希活动的改善。尽管哈希活动的活动增加了100亿倍，总能源消耗增加了100万倍，但自2010年以来，我们发现相对于交易数量的成本并没有增加或减少。这与以下角度相一致，即确保区块链系统安全，可以通过双重支出攻击或运行的价值来转移的价值，因此可以通过网络进行交易。我们估计，在比特币网络中，这一部分的顺序为1％。
The Bitcoin network is burning a large amount of energy for mining. In this paper we estimate the lower bound for the global energy cost for a period of ten years from 2010, taking into account changing oil costs, improvements in hashing technologies and hashing activity. Despite a ten-billion-fold increase in hashing activity and a ten-million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since 2010. This is consistent with the perspective that, in order to keep a the Blockchain system secure from double spending attacks, the proof or work must cost a sizable fraction of the value that can be transferred through the network. We estimate that in the Bitcoin network this fraction is of the order of 1%.
