These services allow the creation of secure containers that are used to execute the chaincode.
Components in this category are as follows: Secure container: Chaincode is deployed in Docker containers that provide a locked down sandboxed environment for smart contract execution.
Writing and Deploying Smart Contracts on Fabric
Currently, Golang is supported as the main smart contract language, but any other mainstream languages can be added and enabled if required.
Secure registry: This provides a record of all images containing smart contracts.
Events Events on the blockchain can be triggered by endorsers and smart contracts.
External applications can listen to these events and react to them if required via event adapters.
They are similar to the concept of events introduced in solidity in , Introducing Web3.
APIs and CLIs An application programming interface provides an interface into the fabric by exposing various REST APIs.
Why This Matters for Blockchain Technology
Additionally, command-line interfaces that provide a subset of REST APIs and allow for quick testing and limited interaction with the blockchain are also available.
