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.
Catalyst Blockchain Platform supports Hyperledger Fabric v2.0 capabilities with the following chaincode lifecycle:
Committing chaincode to the channel flow
The current version of Catalyst BP 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.
