论文摘要
当真相可用时，共识是不必要的。在本文中，我们提出了一个新的观点，即在没有共识的情况下重建区块链。当从区块链中消除共识阶段时，可以使用明确定义的通用规则快速将交易构成，而无需消耗哈希功率。因此，这种共识区块链的每秒交易（TPS）可以在很大程度上得到增强。尽管共识区块链是有希望的，但一些技术挑战也至关重要。例如，必须防止双重支出攻击和频繁的分叉事件，必须仔细定义Block铸造的信用，等等。以应对这些技术挑战，我们为我们的无味区块链（CB）提出了几种解决方案，包括幼稚的单调评分机制，以计算链中每个障碍的排名，以便添加两阶段的证人机构。拟议的CB连锁店有望为丰富的现实世界化应用程序提供简化且廉价的基础设施。
Consensus is unnecessary when the truth is available. In this paper, we present a new perspective of rebuilding the blockchain without consensus. When the consensus phase is eliminated from a blockchain, transactions could be canonized quickly using a well-defined universal rule without consuming hashing power. Thus, the transactions per second(TPS) metric of such the consensusless blockchain can be largely boosted. Although consensus blockchain is promising, several technical challenges are also crucial. For example, double-spending attacks and frequent forking events must be prevented, the credit of block's minting must be carefully defined, and etc. To address those technical challenges, we propose several solutions for our consensusless blockchain (CB), including a naive monotonic scoring mechanism to calculate the ranking of each block in the chain, and a two-stage witness mechanism to add new blocks. The proposed CB chain is promising to offer a simplified and equipment-cheap infrastructure for rich real-world decentralized applications.
