Hyperledger fabric blockchain
Hyperledger Fabric is a set of tools for creating blockchain applications. Championed by the Linux Foundation, it was built from the ground up with enterprise distributed ledger uses in mind. It has a rich ecosystem of components that can be plugged into a modular architecture. It works well in closed blockchain deployments, which can improve security and speed. It also supports an open smart contract model that can support various data models, such as account and unspent transaction output (UTXO) models.
Hyperledger Fabric can also improve data privacy by isolating transactions in channels or enabling the sharing of private data on a need-to-know basis in private data collections. It also enables high-speed transactions with low latency of finality and confirmation, according to its proponents. It is supported by leading cloud providers including Amazon Web Services, IBM, Google, Microsoft Azure and Oracle.
Arnaud Le Hors, senior technical staff member of blockchain, edge computing and web open technologies at IBM, said the latest developments add support for an organization to join a channel without copying the whole history of the ledger. This enables a quicker startup process with less storage required. There is an active and diverse community around Hyperledger Fabric that is working on adding more features related to consensus algorithms, additional privacy options for GDPR compliance and operational improvements.
