摘要

许可区块链协议通常使用基于投票的算法来达成共识。扩展这样的协议很困难，因为它们的消息复杂性很高，因此应用程序数量有限。银行和医疗区块链等用例需要可扩展的分布式协议来维护分类账的一致性并确保其安全性。本文介绍了Colosseum，这是一种为许可区块链系统设计的可扩展共识协议。它是一个基于淘汰赛的协议，在一个结构化的环形网络上，对下一组区块提议者达成共识。每次比赛中，参与者都要参加一种新颖的双人游戏，以获得提议阻挡的资格。Colosseum引入了Proof-of-Win作为比赛结果的证书，以一种高效简便的方式提出可信块并对其进行验证。

Colosseum: A Scalable Permissioned Blockchain over Structured Network

Permissioned blockchain protocols generally use voting based algorithms to reach consensus. Scaling such protocols is hard because of their high message complexity and thus, have a limited number of applications. Use cases like banking and healthcare blockchain require a scalable distributed protocol to maintain the consistency of the ledger and ensure its safety. This paper presents Colosseum, a scalable consensus protocol designed for permissioned blockchain systems. It is a knockout tournament based protocol over a structured ring network to reach consensus on the next set of block proposers. Participants compete in the rounds of a novel two-player game in each tournament to become eligible to propose block. Colosseum introduces Proof-of-Win as the certificate for the result of matches to have an efficient and easy way to propose trusted blocks and verify them.
