论文摘要
由于其最少的能量要求，POS共识方案已成为现代加密货币中POW的一种有吸引力的替代方法。在此协议中，在每个回合中被选为块提议者的机会与任何节点的当前股物成正比。因此，具有较高赌注的节点将获得更多的块奖励，从而导致所谓的丰富富裕人问题。在本文中，我们引入了一种称为FRD（公平奖励分布）机制的新的块奖励机制，其中除了给予块提议者的重大奖励外，每个块还会给出所有其他节点。我们证明，这种奖励机制通过在Bagchi-pal urn模型上发展而使POS协议在财富的集中度上更加公平。
Due to its minimal energy requirement the PoS consensus protocol has become an attractive alternative to PoW in modern cryptocurrencies. In this protocol the chance of being selected as a block proposer in each round is proportional to the current stake of any node. Thus, nodes with higher stakes will achieve more block rewards, resulting in the so-called rich-getting-richer problem. In this paper, we introduce a new block reward mechanism called the FRD (Fair Reward Distribution) mechanism, in which for each block produced, in addition to a major reward given to the block proposer, a small reward is given to all other nodes. We prove that this reward mechanism makes the PoS protocol fairer in terms of concentration of wealth by developing on the Bagchi-Pal urn model.
