Is it possible / how to build a Beefy super light client for Kusama or Polkadot?
Beefy is designed to make the syncing process and finality proof very succinct to enable Ethereum on-chain light client. I want to build a super light client that can validate the storage at some recent blocks but doesn't require to download the full relay chain history. We used to have a GRANDPA light client, but to validate the recent storage proof, it has to sync all the historical blocks. Therefore the client must have the access to a full Kusama archive node with over 600 GiB database.
I've already read the Beefy docs from here. However it's still unclear how to build a light client that can only sync from a pruned relay chain node.
