Runtime API
External node components handle most of the logic such as peer discovery, transaction pooling, block and transaction propagations, consensus mechanisms, and RPC requests. In some cases, external components require some data that is provided by the Runtime. Thus, the Runtime API allows the Runtime and external components to communicate easily with each other.
The API definitions below are the Runtime APIs supported on the Bifrost Network.
