In this technical article, we take a deep look into the consensus engine of the polygon pos network and device a means by which we can implement an ISMP consensus client that safely verifies the polygon blocks.

Polygon is a proof of stake network using clique consensus for block authoring, Polygon POS network comprises two chains, a validator selection chain that uses tendermint
