The scaling hierarchy in blockchains:Computation > data > stateComputation is easier to scale than data. You can parallelize it, require the block builder to provide all kinds of "hints" for it, or just replace arbitrary amounts of it with a proof of it.Data is in the middle. If an availability guarantee on data is required, then that guarantee is required, no way around it. But you _can_ split it up and erasure code it, a la PeerDAS. You can do graceful degradation for it: if a node only has 1/10 the data ...
