Hyperledger Fabric

All transactions taking place on Hyperledger Fabric are executed and processed through chaincode. Each chaincode runs in a secured Docker container that is isolated from the endorser peer process; however, it is orchestrated by the peer node. The state created by the chaincode contract is exclusively accessible to that chaincode, and it can't be accessed directly by other chaincode. However, within the same network and granted the right permissions, a chaincode is allowed to invoke another chaincode to access its state. Each peer is responsible for managing the chaincode container's lifecycle and networking. To interact with the chaincode deployed on these containers, the peer acts as a proxy and offers chaincode APIs (CLI, ...
