raft - Golang implementation of the Raft consensus protocol

•    Go

raft is a Go library that manages a replicated log and can be used with an FSM to manage replicated state machines. It is a library for providing consensus.The use cases for such a library are far-reaching as replicated state machines are a key component of many distributed systems. They enable building Consistent, Partition Tolerant (CP) systems, with limited fault tolerance as well.

Atomix is an event-driven framework for coordinating fault-tolerant distributed systems built on the Raft consensus algorithm. It provides the building blocks that solve many common distributed systems problems including group membership, leader election, distributed concurrency control, partitioning, and replication.

tikv - Distributed transactional key value database powered by Rust and Raft

•    Rust

Geo-Replication TiKV uses Raft and Placement Driver to support Geo-Replication.Horizontal scalability With Placement Driver and carefully designed Raft groups, TiKV excels in horizontal scalability and can easily scale to 100+ TBs of data.

rqlite - The lightweight, distributed relational database built on SQLite.

•    Go

rqlite is a distributed relational database, which uses SQLite as its storage engine. rqlite uses Raft to achieve consensus across all the instances of the SQLite databases, ensuring that every change made to the system is made to a quorum of SQLite databases, or none at all. It also gracefully handles leader elections, and tolerates failures of machines, including the leader. rqlite is available for Linux, OSX, and Microsoft Windows.rqlite gives you the functionality of a rock solid, fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed relational data store. Think etcd or Consul, but with relational data modelling also available.

etcd - Distributed reliable key-value store for the most critical data of a distributed system

•    Go

Note: The master branch may be in an unstable or even broken state during development. Please use releases instead of the master branch in order to get stable binaries. etcd is written in Go and uses the Raft consensus algorithm to manage a highly-available replicated log.

dragonboat - A feature complete and high performance multi-group Raft library in Go.

•    Go

Dragonboat is a high performance multi-group Raft consensus library in Go with C++11 binding support. Consensus algorithms such as Raft provides fault-tolerance by alllowing a system continue to operate as long as the majority member servers are available. For example, a Raft cluster of 5 servers can make progress even if 2 servers fail. It also appears to clients as a single node with strong data consistency always provided. All running servers can be used to initiate read requests for aggregated read throughput.

tikv - Distributed transactional key-value database, originally created to complement TiDB

•    Rust

TiKV is an open-source, distributed, and transactional key-value database. Unlike other traditional NoSQL systems, TiKV not only provides classical key-value APIs, but also transactional APIs with ACID compliance. Built in Rust and powered by Raft, TiKV was originally created to complement TiDB, a distributed HTAP database compatible with the MySQL protocol. The design of TiKV ('Ti' stands for titanium) is inspired by some great distributed systems from Google, such as BigTable, Spanner, and Percolator, and some of the latest achievements in academia in recent years, such as the Raft consensus algorithm.

•    Go

Hyperledger Burrow is a permissioned Ethereum smart-contract blockchain node. It executes Ethereum EVM smart contract code (usually written in Solidity) on a permissioned virtual machine. Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Project information generally updated on a quarterly basis can be found on the Hyperledger Burrow Wiki.

hraftd - A reference use of Hashicorp's Raft implementation

•    Go

For background on this project check out this blog post. hraftd is a reference example use of the Hashicorp Raft implementation v1.0. Raft is a distributed consensus protocol, meaning its purpose is to ensure that a set of nodes -- a cluster -- agree on the state of some arbitrary state machine, even when nodes are vulnerable to failure and network partitions. Distributed consensus is a fundamental concept when it comes to building fault-tolerant systems.

cita - A fast and scalable blockchain for enterprise users.

•    Rust

CITA is a fast and scalable blockchain for enterprises. CITA supports both native contract and EVM contract, by which enterprise users can build their own blockchain applications. CITA has a unique architecture which enables enterprise users to release all their computing resources. Customizable and Pluggable Components: CITA's microservices are loosely coupled and their communications are only via the message queue. Hence, it‘s flexible to improve current components with better algorithms (such as new consensus algorithms) or more appropriate technical solutions (such as new DBs or new privacy solutions). Moreover, business logic is extremely complicated in enterprise applications. With CITA, you can easily customize your blockchain with the certain feature to fit your own business requirements.
