 <p>Relay chain block authorship authority is governed by BABE and is beyond the scope of the Overseer and the rest of the subsystems. That said, ultimately the block author needs to select a set of backable parachain candidates and other consensus data, and assemble a block from them. This subsystem is responsible for providing the necessary data to all potential block authors. </p>
 <h2 id="provisionable-data"><a class="header" href="#provisionable-data">Provisionable Data</a></h2>
 <p>There are several distinct types of provisionable data, but they share this property in common: all should eventually be included in a relay chain block.</p>
