Blockchain open source framework

Hyperledger Fabric is an open source, permissioned blockchain framework, started in by The Linux Foundation. It is a modular, general-purpose framework that offers unique identity management and access control features, which make it suitable for a variety of industry applications such as track-and-trace of supply chains, trade finance, loyalty and rewards, as well as clearing and settlement of financial assets. Blockchain is a technology that makes it possible to build applications where multiple parties can record transactions directly, without the need for a trusted, central authority to ensure that the transactions are verified. Blockchain enables this with the help of a peer-to-peer network where each participant in the network has access to a shared ledger where the transactions are recorded. These transactions are by design, immutable and cryptographically verifiable. At a high-level, blockchain technology consists of three components: a distributed ledger, consensus algorithm, and smart contracts.

ANZ Bank joins open source blockchain project

Hyperledger or the Hyperledger project is an umbrella project of open source blockchains and related tools, started in December by the Linux Foundation , [1] and has received contributions from IBM , Intel and SAP Ariba , to support the collaborative development of blockchain -based distributed ledgers. The founding members of the project were announced in February and ten further members and the makeup of the governing board were announced March The objective of the project is to advance cross-industry collaboration by developing blockchains and distributed ledgers, with a particular focus on improving the performance and reliability of these systems as compared to comparable cryptocurrency designs so that they are capable of supporting global business transactions by major technological, financial and supply chain companies.

Early on there was some confusion that Hyperledger would develop its own bitcoin-type cryptocurrency, but Behlendorf has unreservedly stated that the Hyperledger Project itself will never build its own cryptocurrency. In early , the project began accepting proposals for incubation of codebases and other technologies as core elements.

In January , Hyperledger released the production-ready Sawtooth 1. Hyperledger Fabric is a permissioned blockchain infrastructure, originally contributed by IBM and Digital Asset , providing a modular architecture with a delineation of roles between the nodes in the infrastructure, execution of Smart Contracts called "chaincode" in Fabric and configurable consensus and membership services. A Fabric Network comprises 1 "Peer nodes", which execute chaincode, access ledger data, endorse transactions and interface with applications; 2 "Orderer nodes" which ensure the consistency of the blockchain and deliver the endorsed transactions to the peers of the network; and 3 Membership Service Providers MSPs , each generally implemented as a Certificate Authority, managing X.

It is therefore potentially more flexible than competitors that only support a closed Smart Contract language. Hyperledger Iroha is being used in Cambodia to create a new payment system alongside the National Bank of Cambodia, [15] and in various other projects across healthcare, finance and identity management. Originally contributed by Intel, Sawtooth includes a dynamic consensus feature enabling hot swapping consensus algorithms in a running network.

Among the consensus options is a novel consensus protocol known as "Proof of Elapsed Time," a lottery-design consensus protocol that optionally builds on trusted execution environments provided by Intel's Software Guard Extensions SGX. Besu is an enterprise-grade Ethereum codebase. Hyperledger Caliper is a blockchain benchmark tool and one of the Hyperledger projects hosted by The Linux Foundation.

Hyperledger Caliper allows users to measure the performance of a specific blockchain implementation with a set of predefined use cases. Hyperledger Caliper will produce reports containing a number of performance indicators, such as TPS Transactions Per Second , transaction latency, resource utilisation etc.

The intent is for Caliper results to be used by other Hyperledger projects as they build out their frameworks, and as a reference in supporting the choice of a blockchain implementation suitable for a user's specific needs.

Hyperledger Cello is a blockchain module toolkit and one of the Hyperledger projects hosted by The Linux Foundation. Hyperledger Cello aims to bring the on-demand "as-a-service" deployment model to the blockchain ecosystem to reduce the effort required for creating, managing and terminating blockchains. It provides a multi-tenant chain service efficiently and automatically on top of various infrastructures, e. Hyperledger Composer was a set of collaboration tools for building blockchain business networks that make it simple and fast for business owners and developers to create smart contracts and blockchain applications to solve business problems.

Built with JavaScript, leveraging modern tools including node. Blockchain package management tooling contributed by IBM. Composer was a user-facing rapid prototyping tooling, running on top of Hyperledger Fabric, which allows the easy management of Assets data stored on the blockchain , Participants identity management, or member services and Transactions Chaincode, a.

Smart Contracts, which operate on Assets on the behalf of a Participant. The resulting application can be exported as a package a BNA file which may be executed on a Hyperledger Fabric instance, with the support of a Node. Composer provided a GUI user interface "Playground" for the creation of applications, and therefore represents an excellent starting point for Proof of Concept work.

Hyperledger Explorer is a blockchain module and one of the Hyperledger projects hosted by The Linux Foundation. Designed to create a user-friendly Web application, Hyperledger Explorer can 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 Quilt is a business blockchain tool and one of the Hyperledger projects hosted by The Linux Foundation. Hyperledger Quilt offers interoperability between ledger systems by implementing the Interledger protocol also known as ILP , which is primarily a payments protocol and is designed to transfer value across distributed ledgers and non-distributed ledgers.

The Interledger protocol provides atomic swaps between ledgers even non-blockchain or distributed ledgers and a single account namespace for accounts within each ledger.
