Hyperledger is an open-source community focused on developing a suite of stable frameworks, tools, and libraries for enterprise-grade blockchain deployments. Hyperledger incubates and promotes a range of business blockchain technologies, including distributed ledger frameworks. A distributed ledger is a multi-party database with no central trusted authority. The differentiating nuance is that when transactions are processed in blocks according to the ordering of a blockchain, the result is a distributed ledger. Open-source distributed ledger frameworks hosted at Hyperledger include Hyperledger Besu, Burrow, Fabric, Indy, Iroha and Sawtooth.
2. Suggested Distributed Ledgers to use for the Global CBDC Challenge are as follows:
 | 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 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. |

 | 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. |

- Where can I get technical help regarding one of the Hyperledger projects? Hyperledger projects are open source projects and are supported via the community. If you have any questions regarding the different projects, the mailing lists and chat are a good place to reach out. We have mailing lists and chat channels for each of the different projects.
Hyperledger in Action for CBDCs
Hyperledger Besu
Hyperledger Premier Member ConsenSys uses Hyperledger Besu for a Bank of Thailand proof-of-concept prototype for a CBDC project, alongside SCG and Digital Ventures. The private-permissioned network on Hyperledger Besu was designed to meet both the functional and non-functional requirements of a retail CBDC. One of the business cases tested the use of a CBDC to simulate daily commerce, automate payments, and support procurement and financial management system called Procure-to-Pay (B2P) developed by DV.

Bank of Australia has also partnered with ConsenSys to develop a POC for the issuance of a tokenised form of CBDC that can be used by wholesale market participants for the funding, settlement, and repayment of a tokenised syndicated loan on an Ethereum-based DLT platform. https://consensys.net/blog/press-release/reserve-bank-of-australia-partners-with-commonwealth-bank-national-australia-bank-consensys-perpetual-on-wholesale-cbdc-project/
CBDC pilot using Hyperledger Fabric completed by The central banks of Saudi Arabia and the United Arab Emirates (UAE) found that distributed ledger technology can improve cross-border transactions and meet the demands of financial privacy in a purely digital context. In this report on Project Aber, the two central banks outlined the lessons learned from a yearlong proof-of-concept meant to test the viability of a shared digital currency.
Hyperledger Fabric
Eastern Caribbean Central Bank (ECCB) has launched a pilot retail CBDC called “DCash” using Hyperledger Fabric. Partnering with Bitt Inc., ECCB shared in a recent OECD presentation that it selected Hyperledger Fabric because of its strong security architecture (private permissioned blockchain with strong identity management) and open source code, which contributes to its security, flexibility and scalability among other desired attributes. Also, watch their recent presentation to the Hyperledger Capital Markets SIG.
Fnality, in partnership with Adhara is using Hyperledger Besu for a wholesale payments system representing USD, euro, JPY, GBP and CAD that will allow wholesale banking transactions to happen instantly, cross-border and 24/7. Watch their recent presentation to the Hyperledger Capital Markets SIG.
Hyperledger Iroha
Hyperledger Case Study: The National Bank of Cambodia's Project Bakong boosts financial inclusion with Hyperledger Iroha and was recognized by PwC in their Global CBDC Index as #2 Retail CBDC globally and #1 in Asia. This is the first large-scale quasi-CBDC in production. https://www.hyperledger.org/learn/publications/soramitsu-case-study
