Polygon (PIP-11) Consensus Client

[seunlanlege]

The existing Polygon consensus client tries to use the clique protocol on Bor (Polygon's execution layer) as a source for finality proofs. In practice, these proofs are unreliable and prone to frequent reorgs.

Rather than relying entirely on Bor, a polygon core dev has pointed out that we should instead rely on Heimdall (Polygon's consensus layer) for finality proofs. This is possible with the recent introduction of PIP-11. A protocol in which Heimdall's validators finalize Bor's blocks. Heimdall itself is a cosmos-sdk chain which uses a tendermint-based consensus mechanism.

This is a tracking issue for Polygon's deterministic finality mechanism on Hyperbridge
