This involves abstracting the existing monitoring logic into programs that can be readily instantiated in a runtime. The runtime will provide an API for the programs to access chain data, store intermediate data and emit events.

The server will consist of the program runtime, where multiple monitoring programs can be executed. Each monitoring program encapsulates predefined monitoring logic with its own configuration, also known as the program manifest. Each instantiation of a monitoring program is known as a monitoring agent that accepts subscriptions through its subscription API. The programs running in the runtime will access the persistent storage, the multi-chain connectors and the delivery mechanism through the runtime API.
