        <h3>IPA polynomial commitment by hand</h3>

<p>This post overviews the IPA polynomial commitment described in the Halo paper, first by providing an overview on the protocol, then by doing a step-by-step example with small values, following the style done in the &ldquo;Plonk by hand series&rdquo; from Joshua Fitzgerald, and later by providing a Sage implementation of the protocol.</p>
