论文摘要
哲学市场区块链系统是一个提出的层次结构架构,允许大量单独的区块链并行操作。这些平行连锁店在有限的核心操作集中达成共识,同时允许每个链上应用程序独立于其他人来管理自己的数据。 该体系结构解决了传统线性区块链的可扩展性问题,但需要新颖的共识机制。哲学共识机制的一个核心特征是其信任算法,该算法为每个网络节点分配一个数值信任值(或分数),表明最近的表现质量。 然后,该信任值用于确定节点的投票权重,以更高的共识级别。在本文中,我们正式定义了哲学信托算法,并在理论上和经验上提供了其运作的几个插图。我们还询问一个行为不端的节点是否可以从战略上利用算法为其个人利益利用该算法,并证明可以通过仅对每个平行链中的参与者的数量进行温和的限制来普遍预防这种剥削。
The Philos Marketplace blockchain system is a proposed hierarchical blockchain architecture which allows a large number of individual blockchains to operate in parallel. These parallel chains achieve consensus among one another on a limited set of core operations, while allowing each on-chain application to manage its own data independently of others. This architecture addresses the scalability issues of traditional linear blockchains, but requires novel consensus mechanisms. A central feature of the Philos consensus mechanism is its trust algorithm, which assigns each network node a numerical trust value (or score) indicating the quality of recent past performance. This trust value is then used to determine a node's voting weight at the higher levels of consensus. In this paper, we formally define the Philos trust algorithm, and provide several illustrations of its operation, both theoretically and empirically. We also ask whether a misbehaving node can strategically exploit the algorithm for its personal gain, and show that this type of exploitation can be universally prevented simply by enforcing a mild limit on the number of participants in each of the parallel chains.
