I asked this before but forgot.. Do we benefit much from compressed PoVs? I'd assume our merkle proofs wind up incompressible? Or did we mess up sometihng there and it would up easier to just compress them? Or maybe this is just the actual block data? |

We did not really test it. I would say it depends on the data that is part of the state proof. |

While compact encoding is used for extrinsic, they are not (generally) used for storages. So that means balances will have a lot of empty bytes which are potentially compressible. |
