const MAX_PROOF_HASHES: usize = _; // 1_560_704usizeExpand description
The maximum number of proof hashes that can be included in a Utreexo proof.
Assuming that each UTXO needs a proof, with no overlaps of any kind, the maximum number of
proof hashes is the number of inputs per block multiplied by the maximum number of
elements that each proof requires, in a tree with MAX_TREE_DEPTH depth.
