论文摘要
工作证明（POW）是比特币成立以来使用的流行共识协议。 POW具有将所有奖励分配给插入新块的单个矿工（或游泳池）的众所周知的缺陷。这是由于使奖励的差异以及采矿企业的风险极高的结果。为了解决这个问题，SHI在2016年提出了一种理论算法，该算法将大大减少该问题。我们介绍了一系列的工作证明，可以改善什叶的想法，并且可以在实践中很容易实施。为了插入一个块，网络不得找到一个nonce，而必须找到其中一些。这种微小的更改允许更公平地分配奖励，同时可以正规化块的插入时间。这将有助于小型游泳池或自动矿工的出现。
Proof-of-Work (PoW) is a popular consensus protocol used by Bitcoin since its inception. PoW has the well-known flaw of assigning all the reward to the single miner (or pool) that inserts the new block. This has the consequence of making the variance of the reward and thus the mining enterprise risk extremely high. To address this problem, Shi in 2016 proposed a theoretical algorithm that would substantially reduce the issue. We introduce a variant of Proof-of-Work that improves on Shi's idea and can be easily implemented in practice. In order to insert a block, the network must not find a single nonce, but must find a few of them. This small change allows for a fairer distribution of rewards and at the same time has the effect of regularizing the insertion time of blocks. This would facilitate the emergence of small pools or autonomous miners.
