Due to the 2nd law of thermodynamics, it is impossible to convert anything to energy and back without extra energy as input. So this hypothetical arrangement can't happen.
Basically it's a matter of quotation units. One energy coin can be exchanged for one joule, but it takes more than one joule to be mined, or one joule is mined for one energy coin, only to convert to less than one. Each energy coin must definitely be converted to the same amount of energy.
比特币代表的是能源和算力。 我猜比特币是当前文明过渡到下一文明阶段的一个大过滤器。 #ValueForBehavior
按工作量不按人头，是因为在去中心的网络环境里我无法知道你有多少人头啊，我只能看考勤不是吗？？你干了一万人的活，我就给你算一万人。
