NDSS 2025 – Mysticeti: Reaching The Latency Limits With Uncertified DAGs
嗯，用户让我帮忙总结一下这篇文章的内容，控制在100字以内。首先，我需要仔细阅读文章，抓住主要信息。文章标题是“ Mysticeti: Reaching The Latency Limits With Uncertified DAGs”，看起来是关于网络共识协议的。
作者们来自Mysten Labs和其他机构，他们提出了Mysticeti-C和Mysticeti-FPC这两个协议。这两个协议基于DAG结构，提高了效率和抗审查能力。特别是Mysticeti-C达到了3个消息轮次的延迟下限，而FPC进一步优化了资产转移的延迟。
文章还提到这些协议在实际应用中的表现，比如在广域网中达到0.5秒的共识提交延迟，并且吞吐量超过10万TPS。此外，他们将Mysticeti-C集成到一个主要的区块链中，减少了4倍的延迟。
接下来，我需要把这些信息浓缩到100字以内。重点包括：DAG共识协议、低延迟、高吞吐量、资源效率、抗审查能力以及实际应用效果。
可能会忽略一些技术细节，比如具体的commit规则和签名优化，但这些对总结来说可能不太重要。确保涵盖主要贡献和结果。
最后，检查一下字数是否符合要求，并确保语言简洁明了。

文章介绍了一种基于DAG的拜占庭共识协议Mysticeti-C及其扩展版本Mysticeti-FPC，通过避免显式认证和创新提交规则，在实现低延迟的同时保持高吞吐量和资源效率。该协议在广域网中实现了0.5秒的共识提交延迟，并成功应用于实际区块链系统中，显著降低了延迟。

PAPER
Mysticeti: Reaching The Latency Limits With Uncertified DAGs
We introduce Mysticeti-C, the first DAG-based Byzantine consensus protocol to achieve the lower bounds of latency of 3 message rounds. Since Mysticeti-C is built over DAGs it also achieves high resource efficiency and censorship resistance. Mysticeti-C achieves this latency improvement by avoiding explicit certification of the DAG blocks and by proposing a novel commit rule such that every block can be committed without delays, resulting in optimal latency in the steady state and under crash failures. We further extend Mysticeti-C to Mysticeti-FPC, which incorporates a fast commit path that achieves even lower latency for transferring assets. Unlike prior fast commit path protocols, Mysticeti-FPC minimizes the number of signatures and messages by weaving the fast path transactions into the DAG. This frees up resources, which subsequently result in better performance. We prove the safety and liveness in a Byzantine context. We evaluate both Mysticeti protocols and compare them with state-of-the-art consensus and fast path protocols to demonstrate their low latency and resource efficiency, as well as their more graceful degradation under crash failures. Mysticeti-C is the first Byzantine consensus protocol to achieve WAN latency of 0.5s for consensus commit while simultaneously maintaining state-of-the-art throughput of over 100k TPS. Finally, we report on integrating Mysticeti-C as the consensus protocol into a major deployed blockchain, resulting in over 4x latency reduction.
ABOUT NDSS
The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies.
