This is going to be a problem, no? If we no longer have the requests in the block I don't think we'll be able to return them from GetPayloadBodiesByXXX ?

kinda weird to just have the deposit request prefix just as a bare 0 value here instead of named?

It can be rewrote to following to eliminate memory allocation
func CalcRequestsHash(requests [][]byte) common.Hash {
h1, h2 := sha256.New(), sha256.New()
var buf common.Hash
for _, item := range requests {
h1.Reset()
h1.Write(item)
h2.Write(h1.Sum(buf[:0]))
}
h2.Sum(buf[:0])
return buf
}There was a problem hiding this comment.
This is a very clever suggestion!

Block no longer has Requests. This PR just removes some code that wasn't removed in #30425.
