Hyperledger is a community started by Linux foundation. Each frameworks under Hyperledger has a Vendor as Initial Contributor. For Example, IBM initiated Hyperledger Fabric, Intel initiated Hyperledger Sawtooth.
Each of these frameworks are focussed on most common business cases. Because of its permissioned-network structure, this can be made to be open only within an intranet or an organization or a group of organization.
Each Hyperledger framework has a different consensus approach because each of them were focussed on a core business case. For Example, Sawtooth uses Proof of elapsed Time as a consensus strategy because most of the Sawtooth’s architecture were focussed to adapt uses cases that uses IoT, where the inputs would be fed every second or half a second.
Hyperledger Fabric consensus mechanisms, which currently include SOLO, Kafka, and will soon extend to SBFT (Simplified Byzantine Fault Tolerance),
