Consensys Quorum
ConsenSys Quorum enables enterprises to leverage Ethereum for their high-value blockchain applications. Businesses can rely on the Quorum open-source protocol layer and integrate on top of it product modules from ConsenSys, other companies, or your own in-house development team to build high-performance, customizable applications. Our mission is the seamless adoption of blockchain technology. On top of ConsenSys Quorum, you can integrate product modules from ConsenSys, third-party vendors, or your own in-house developers to build high-performance, customizable applications. ConsenSys Quorum consists of two open-source projects, one based on Hyperledger Besu and another on GoQuorum. ConsenSys Quorum Blockchain Service Support is a subscription-based support service providing developers and businesses with on-demand, developer, or production support for the Quorum open-source protocol projects, plus additional tooling and upgrades to ensure the success of your production system.

Hyperledger Indy
Hyperledger Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo. Indy is interoperable with other blockchains or can be used standalone powering the decentralization of identity. Distributed ledger purpose-built for decentralized identity, correlation-resistant by design. DIDs (Decentralized Identifiers) that are globally unique and resolvable (via a ledger) without requiring any centralized resolution authority. Pairwise Identifiers create secure, 1:1 relationships between any two entities. Verifiable claims are interoperable format for exchange of digital identity attributes and relationships currently in the standardization pipeline at the W3C. Zero Knowledge Proofs which prove that some or all of the data in a set of Claims is true without revealing any additional information.

Hyperledger Besu
Hyperledger Besu is an Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases. It can also be ran on test networks such as Rinkeby, Ropsten, and Görli. Hyperledger Besu includes several consensus algorithms including PoW, and PoA (IBFT, IBFT 2.0, Etherhash, and Clique). Its comprehensive permissioning schemes are designed specifically for use in a consortium environment. Hyperledger Besu implements the Enterprise Ethereum Alliance (EEA) specification. The EEA specification was established to create common interfaces amongst the various open and closed source projects within Ethereum, to ensure users do not have vendor lock-in, and to create standard interfaces for teams building applications. Besu implements enterprise features in alignment with the EEA client specification. Hyperledger Besu implements various consensus algorithms which are involved in transaction validation, block validation, and block production.

Hyperledger Iroha
Hyperledger Iroha is designed to be simple and easy to incorporate into infrastructural or IoT projects requiring distributed ledger technology. Hyperledger Iroha features a simple construction, modular, domain-driven C++ design, emphasis on client application development and a new, crash fault tolerant consensus algorithm, called YAC. Hyperledger Iroha is a simple blockchain platform you can use to make trusted, secure, and fast applications by bringing the power of permission-based blockchain with Crash fault-tolerant consensus. It’s free, open-source, and works on Linux and Mac OS, with a variety of mobile and desktop libraries. Hyperledger Iroha is a general purpose permissioned blockchain system that can be used to manage digital assets, identity, and serialized data. This can be useful for applications such as interbank settlement, central bank digital currencies, payment systems, national IDs, and logistics, among others.
