Hmm looks like you need to specify some extradata in the genesis block, otherwise the snapshot() function will panic , because make([]byte, len(header.extradata) - 32 - 65 / 20) is make([]byte, -3)
So just adding some extraData to the genesis should fix the issue. But we should probably add some check to prevent this from panicing
