在块DAG中嵌入确定性BFT协议

Embedding a Deterministic BFT Protocol in a Block DAG

Maria A Schett, George Danezis

摘要:

这项工作形式化的结构和协议,最近的分布式系统利用块DAG,这基本上是编码Lamport的发生之前的块之间的关系,作为其核心网络原语。然后,我们提出了一个嵌入的任何确定性拜占庭容错协议$\mathcal{P}$采用块DAG解释服务器之间的交互。我们的主要定理证明了这种嵌入保持了$\mathcal{P}$的所有安全性和活性特性。从技术上讲,我们的定理是基于这样的见解,即块DAG仅充当P实例之间的有效可靠的点对点通道,同时还使用$\mathcal{P}$进行有效的消息压缩。

英文摘要:

This work formalizes the structure and protocols underlying recent distributed systems leveraging block DAGs, which are essentially encoding Lamport's happened-before relations between blocks, as their core network primitives. We then present an embedding of any deterministic Byzantine fault tolerant protocol $\mathcal{P}$ to employ a block DAG for interpreting interactions between servers. Our main theorem proves that this embedding maintains all safety and liveness properties of $\mathcal{P}$. Technically, our theorem is based on the insight that a block DAG merely acts as an efficient reliable point-to-point channel between instances of P while also using $\mathcal{P}$ for efficient message compression.
