Hyperledger Fabric Service 2.2.0

Commit a Chaincode to the Channel

Chaincode is a smart contract of Hyperledger Fabric that handles the business logic of a particular application. A smart contract programmatically accesses two distinct pieces of the ledger – a blockchain, which immutably records the history of all transactions, and a world state that holds a cache of the current value of these states.
In other words, a chaincode is programmable code that runs on the peers and facilitates transactions on a Hyperledger Fabric blockchain application allowing the users to update the world state of the assets.
The Catalyst Blockchain Platform Hyperledger Fabric service supports Hyperledger Fabric v2.0 capabilities with the following chaincode lifecycle:
Committing chaincode to the channel flow
The current version of Catalyst Blockchain Platform supports external chaincodes. Organizations do not need to package the chaincode, rather they just need to create a Docker image and provide a link to the Docker repository while adding chaincode in Catalyst Blockchain Platform.
Every organization that will use the chaincode to endorse a transaction or query the ledger needs to complete this step.
Every organization that will use the chaincode needs to complete this step. The chaincode definition needs to be approved by a sufficient number of organizations with endorser rights to satisfy the channel’s policy before the chaincode can be started on the channel.
Any organization could commit a chaincode if all necessary approvals were done.
