OciorCOOL:更快的拜占庭协议与可靠广播

OciorCOOL: Faster Byzantine Agreement and Reliable Broadcast

Jinyuan Chen

AI总结:

本文将四阶段拜占庭协议 COOL 减少一个通信轮次,提出 OciorCOOL,并据此构造仅需六轮的最优可靠广播协议。

摘要:

COOL(Chen'21)是一种无错且确定性的拜占庭协议协议:在包含 n 个节点、其中至多 t 个节点可能不诚实的网络中,当 n≥3t+1 时,它能在四个阶段内就一条 ℓ 比特消息达成共识,通信复杂度为 O(max{nℓ, nt log t}) 比特。在本工作中,我们表明可以通过减少一个通信轮次来优化 COOL。新协议称为 OciorCOOL。此外,在 OciorCOOL 的基础上,我们设计了一种仅需六个通信轮次的最优可靠广播协议。

英文摘要:

COOL (Chen'21) is an error-free and deterministic Byzantine agreement protocol that achieves consensus on an $\ell$-bit message with a communication complexity of $O(\max\{n\ell, n t \log t \})$ bits in four phases, given $n\geq 3t + 1$, for a network of $n$ nodes, where up to $t$ nodes may be dishonest. In this work we show that COOL can be optimized by reducing one communication round. The new protocol is called OciorCOOL. Additionally, building on OciorCOOL, we design an optimal reliable broadcast protocol that requires only six communication rounds.
