should this error out or return empty?

I think this should be the empty requests, we need to guarantee that the slice is not nil before though.

This should be withdrawals requests per payload, not withdrawals

if you are passing an empty request container here anyway, why not use the signature
func processRequestBytes([]byte); (*ExecutionRequests, error)
| } | ||
|
|
||
| // Recursive call with the remaining bytes | ||
| return processRequestBytes(remainingBytes, requests) |

I think a loop instead of a recursive algorithm is better here, the tail recursion elimination in this case is simple.

Pending questions here on whether ordering would matter to the EL. cc @fjl

Closing this because of the spec changes @james-prysm feel free to reopen if you reuse the branch |

What does this PR do? Why is it needed?
implements the serialization of common hash for use in
engine_NewPayloadV4as well as decoding of the byte array inengine_getPayloadV4prerequisite for #14492
