Why does Celestia use a DA scheme that involves fraud proofs of incorrect data encoding? Is there some tradeoff against PeerDAS which doesn't require this?

You should meet Noah when he’s back to nyc @colludingnode 

You’ll get along well. An up and comer in all things blockchain

a polynomial commitment (like KZG) can be used to eliminate the need for encoding fraud proofs. at the moment, the KZG commitment is why Ethereum blobs are restricted to a large fixed size, whereas on Celestia they can be any size between 512 bytes and MAX_BLOCK_SIZE (currently 2MB)

we're not married to the fraud proofs, and are exploring commitment schemes like FRIDA
