Consensus [^7] should guarantee
- **liveness**: system should never stop and should be able to recover from errors
- **security:** nonfaulty peers should not accept false data
- **convergence** (consistency): all non-faulty peers should maintain or converge to the same global ordering and state

>"Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture. Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy."
