Hyperledger framework: Hyperledger business blockchain frameworks are

used to build enterprise blockchains for a consortium of organizations that are

different from public ledgers like the Bitcoin blockchain and Ethereum. The

components of Framework of Hyperledger are Fabric, Burrow, Indy, Grid, and

Hyperledger Tools/ Modules.

SAP, SAP HANA, and Hyperledger: An integration model between

blockchain and SAP HANA, the maj or offering in blockchain technology of

SAP is the SAP Cloud Platform Blockchain Service.

Blockchain service of SAP HANA provides the facility to connect external

blockchain networks to SAP HANA. We can bring blockchain data to an SAP

HANA database or move data from the SAP HANA database onto the

blockchain with the help of this service. It allows us to create analytics not j ust

on blockchain data but also combine it with master or transaction data from the

SAP system.

Service and adapter of SAP HANA: The blockchain adapter of SAP HANA

subscribes to the HANA blockchain services in the cloud, which, in turn,

communicate with the SAP blockchain service.
