A software canister in DFINITY’s Internet Computer is an evolved smart contract with enhanced scalability and computational units. A software canister is similar to a container used by other blockchain systems in that both are deployed as a software unit consisting of compiled code and a mechanism for an application or service. Containerization separates applications from the main blockchain environment, allowing for simple and reliable deployment. A canister, on the other hand, differs from a container in that it also stores data about the current software state as well as a record of numerous previous events and user interactions.
