Executive

Overview

Acts as the orchestration layer for the runtime. Receives incoming extrinsic calls, decodes them and dispatches the calls to the respective modules of the runtime. It uses System library for accessing the low-level storage and performing some important actions during the block production phase.

Example

Runtime API entry Core_initialize_blockcalls initializeBlock function of the Executive module.

export function Core_initialize_block(data: i32, len: i32): u64 {
    const input = Serialiser.deserialiseInput(data, len);
    const header = BytesReader.decodeInto<HeaderType>(input);
    Executive.initializeBlock(header);
    return Serialiser.serialiseResult([]);
}
