When looking at #23277 I noticed that
GetTransactionReceipt
fetches the same block body twice and its header once from storage. This PR targets one of those, i.e. getting the header of a block when that block is already cached inBlockchain
.Alternatively I could warm the headerchain's cache when a block is cached.
This only saves one lookup for each block that's cached (when the header is not)..
