| Hyperledger Avalon is a ledger independent implementation of the Trusted Compute Specifications published by the Enterprise Ethereum Alliance. It aims to enable the secure movement of blockchain processing off the main chain to dedicated computing resources. Avalon is designed to help developers gain the benefits of computational trust and mitigate its drawbacks. |
| Hyperledger Burrow is a complete single-binary blockchain distribution focussed on simplicity, speed, and developer ergonomics. It supports both EVM and WASM based smart contracts and uses BFT consensus via the Tendermint algorithm. It has a sophisticated event system and can maintain a relational database mapping of on-chain data. Governance and permissioning is built in and can be amended by on-chain proposal transactions. It is optimised for public permissioned proof-of-stake use cases but can also be used for private/consortium networks. |
| Hyperledger Cactus is a blockchain integration tool designed to allow users to securely integrate different blockchains. |
| Hyperledger Caliper is a blockchain benchmark tool, it allows users to measure the performance of a blockchain implementation with a set of predefined use cases. Hyperledger Caliper will produce reports containing a number of performance indicators to serve as a reference when using the following blockchain solutions: Hyperledger Besu, Hyperledger Burrow, Ethereum, Hyperledger Fabric, FISCO BCOS, Hyperledger Iroha, and Hyperledger Sawtooth. |
| Hyperledger Cello aims to serve as the operational dashboard for Blockchain, which reduces the effort required for creating, managing and using blockchains. Besides, it can also be used to facilitate creating Blockchain as a Service. Cello provides an operational console for managing blockchain’s efficiently and running on top of various infrastructures, e.g., baremetal, virtual machine, and various container platforms. |
| Hyperledger Explorer is a user-friendly Web application tool used to view, invoke, deploy or query blocks, transactions and associated data, network information (name, status, list of nodes), chain codes and transaction families, as well as any other relevant information stored in the ledger. |
| Hyperledger Grid intends to provide reference implementations of supply chain-centric data types, data models, and smart contract based business logic – all anchored on existing, open standards and industry best practices. It showcases in authentic and practical ways how to combine components from the Hyperledger stack into a single, effective business solution. |
| Hyperledger Quilt is a Java implementation of the Interledger protocol, enabling payments across any payment network — fiat or crypto. Quilt provides an implementation of all core primitives required for sending and receiving payments in a ledger-agnostic manner, allowing developers to write application payments logic once while gaining access to any other payment system that is Interledger-enabled. |
| Hyperledger Transact aims to reduce the development effort in writing distributed ledger software by providing a standard interface for executing smart contracts that is separate from the distributed ledger implementation. Hyperledger Transact takes an extensible approach to implementing new smart contract languages called “smart contract engines,” that implement a virtual machine or interpreter that processes smart contracts. |
| Hyperledger Ursa is a shared cryptographic library, it enables implementations to avoid duplicating other cryptographic work and hopefully increase security in the process. The library is an opt-in repository (for Hyperledger and non Hyperledger projects) to place and use crypto. Hyperledger Ursa consists of sub-projects, which are cohesive implementations of cryptographic code or interfaces to cryptographic code. |
