In this tutorial, we understood why consensus algorithms play a significant role in a distributed system. Moreover, we went through different computing models where these algorithms are expected to work. Finally, we discussed some of the popular voting-based and proof-based consensus algorithms.Categ...
开始在 MSRA 做 Replication/Fault Tolerance 的研究项目开始,到现在满打满算也学了有三年的 Distributed System 了。感谢 Jinglei 一开始的时候给了我大量的时间做 paper reading,开始的几个月基本上把 Distributed Transaction 相关的 paper,还有一些 Distributed System 的基础论文都读了个遍,也上网看了不少相关的...

Raft is an evolution of the Paxos consensus algorithm, and has growing usage in distributed systems used for infrastructure (Hashicorp Consul, etcd and others) as well as business logic services such as a matching engine in a financial trading system. ...
The goal of the consensus protocol is to make all non-faulty processors agree on a common value despite the interference of faulty processors. In the class
How consensus algorithms work Consensus algorithms are vital in large-scale,fault-tolerantsystems because they enable a set of distributed/replicated machinesor servers to work as a coherent group and agree on system state, even in the presence of failures or outages. To achieve this, the algorith...
A consensusalgorithmis a protocol that enables a group of distributed nodes (i.e., computers or servers) to reach an agreement on a single data value or the state of a system. In the context of decentralized networks, consensus algorithms are used to validate and confirm transactions, ensuring...

Two well known Distributed Consensus Algorithms are Paxos and Raft. Paxos is used in systems likeChubbyby Google, and Raft is used in things liketikvoretcd. Raft is generally seen as a more understandable and simpler to implement than Paxos. ...
By designing events such that a specifically chosen Lyapunov function is monotonically decreasing, event-triggered algorithms succeed in reducing communications among agents while still ensuring that the entire system converges to the desired state. However, depending on the chosen Lyapunov function the ...
