To achieve no code or low code parity in decentralized computing systems, disclosed implementations provide a data structure and trusted control plane that enables the creation and operation of composable objects, that is objects whose functions and properties are derived from configurable and upgradable templates. The templates are data structures that define the behavior of a collection of objects, the behaviors being the interfaces, functions, properties, events, triggers, error messages, and dependencies that define and object and its interaction with other objects and entities. Templates are configured by mapping the desired object behaviors to registered smart contract logic that affects the behaviors. Thus, complex objects can be composed without the need for new computer code. Additional logic to enable new behaviors can be added by authorized smart contract developers and, once certified, added to one or more templates to provide the objects access to the new capabilities.
