论文摘要
在本文中，我们探讨了COB应用的上下文，这是最近引入的拜占庭容错共识方案。 COB被证明是一种无领先的共识协议，它在要观察和记录的事件列表的每个组件上并行进行共识过程。我们展示了如何使用COB来定义可扩展和可持续区块链的共识层。该层用于设计基于碎片的共识协议，作为实现可伸缩性的平均值，以及时间段的时间片段化（将其分配给指示创建新块的节点），以减少维护分布式LEDGER的计算和通信量的平均值。我们解释了为什么COB是通过引入我们命名同步链的辅助区块链实现此类共识层的可行候选人。
In this paper we explore a context of application of Cob, a recently introduced Byzantine Fault Tolerant consensus protocol. Cob proves to be a leaderless consensus protocol which carries out the consensus process in parallel on each component of a list of events to be observed and recorded. We show how Cob can be used to define a consensus layer for scalable and sustainable blockchains. This layer is used to design consensus protocols based on sharding as a mean to achieve scalability, and on the fragmentation of time in time-slots (which get assigned to nodes that are instructed to create new blocks) as a mean to reduce the amount of computation and communication necessary for the maintenance of the distributed ledger. We explain why Cob is a viable candidate to implement such consensus layer through the introduction of an auxiliary blockchain that we name Synchronization Chain.
