Hyperledger Project:
The Hyperledger project is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration including leaders in finance, banking, Internet of Things, supply chains, manufacturing and Technology. The Linux Foundation hosts Hyperledger as a Collaborative Project under the foundation.
Projects under Hyperledger Project
Blockchain Explorer
Blockchain-explorer is a project in Incubation that was proposed by Christopher Ferris (IBM), Dan Middleton (Intel) and Pardha Vishnumolakala (DTCC) to create a user friendly web application for Hyperledger to view/query blocks, transactions and associated data, network information (name, status, list of nodes), chain codes/transaction families (view/invoke/deploy/query) and any other relevant information stored in the ledger.
Fabric
Hyperledger fabric is a project in Incubation that was proposed by Tamas Blummer (DAH) and Christopher Ferris (IBM) as a result of the first hackathon during which a merge between IBM’s proposal and DAH’s proposal was started (see Proposal).
fabric is an implementation of blockchain technology that is intended as a foundation for developing blockchain applications or solutions. It offers a modular architecture allowing components, such as consensus and membership services, to be plug-and-play. It leverages container technology to host smart contracts called “chain code” that comprise the application logic of the system.
