Hyperledger Fabric is an enterprise-grade, distributed ledger platform that offers modularity and versatility for a broad set of industry use cases. The modular architecture for Hyperledger Fabric accommodates the diversity of enterprise use cases through plug and play components, such as consensus, privacy and membership services. 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. One of the many compelling Fabric features is the enablement of a network of networks. Members of a network work together, but because businesses need some of their data to remain private, they often maintain separate relationships within their networks.

Nxt is an open source blockchain platform and the first to rely entirely on a proof-of-stake consensus protocol. Launched in November 2013 and written from scratch in Java, Nxt is proof that blockchain technology is not only about simple transfer of value but also has the potential to revolutionize many aspects of our lives with the various decentralized applications that can be built with it. Today, Nxt remains one of the most tested and reliable platforms in the industry, influencing numerous other projects. With its many easy to use modular built-in features, Nxt covers most of the dApp use cases and at the same time is perfectly suitable for private blockchain implementations. Nxt was the first to implement a pure proof-of-stake consensus protocol.
