Project Concord-bft solves this problem by simplifying and streamlining communication between nodes, enabling greater scalability while increasing overall network throughput.\n\nProject Concord’s BFT engine obtains significant scaling improvements via three major advances:\n\n1. It uses a linear communication consensus protocol while many other BFT consensus protocols (including PBFT) require quadratic communication\n2. It exploits optimism to provide a common case fast-path execution\n3. It uses modern cryptographic algorithms (BLS threshold signatures)\n\nIts implementation is based on the algorithm described in the paper [SBFT: a Scalable Decentralized Trust Infrastructure for\nBlockchains](https://arxiv.org/pdf/1804.01626.pdf).\n\nIt is designed to be used as a core building block for replicated distributed data stores, and is especially suited to serve as the basis of permissioned Blockchain systems.\n\nStart with example usage [here](https://github.com/vmware/concord-bft/tree/master/examples).\n\n## Documentation\n\nSee the github [wiki](https://github.com/vmware/concord-bft/wiki) for detailed explanation.\u003c/br\u003e\nA formal specification of the SBFT protocol including automated invariant proofs can be found [here](https://github.com/vmware/concord-bft/tree/master/docs/sbft-formal-model).\n\n## Community\n\n[Concord-BFT Slack](https://concordbft.slack.com/).\n\nRequest a Slack invitation via \u003cconcordbft@gmail.com\u003e.\n\n## License\n\nConcord-bft is available under the [Apache 2 license](LICENSE).\n","funding_links":[],"categories":["C++","Virtualization"],"sub_categories":["VMware"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvmware%2Fconcord-bft","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvmware%2Fconcord-bft","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvmware%2Fconcord-bft/lists"}
