A chaincode can be invoked to update or query the ledger in a proposal transaction. Given the appropriate permission, a chaincode may invoke another chaincode, either in the same channel or in different channels, to access its state. Note that, if the called chaincode is on a different channel from the calling chaincode, only read query is allowed.

Develop, deploy, and upgrade Hyperledger Fabric chaincode on SAP Cloud Platform. Writing, Building, and Running Chaincode in a Development Environment¶ Chaincode developers need a way to test and debug their chaincode without having to set up a complete peer network. By default, when you want to interact with chaincode, you need to first Deploy it using the CLI, REST API, gRPC API, or SDK. Upon receiving this request, the Chaincode initializes and manages the ledger state through transactions submitted by applications. A chaincode typically handles business logic agreed to by members of the network, so it similar to a “smart contract”. Ledger state created by a chaincode is scoped exclusively to that chaincode and can’t be accessed directly by another You will learn chaincode development, testing, and deployment for a Hyperledger Fabric network catering specifically toward Golang written chaincode (Fabric’s original chaincode Language). Additionally, you will learn how to write and prepare Client Applications using the most mature Standard Development Kit in Hyperledger Fabric, NodeJS.
