	// bit 3: (default 0) 0: don't verify that the hash of the recomputed payset matches the hash of the payset committed in the block header; 1: do perform the above verification
	// Note: not all permutations of the above bitset are currently functional. In particular, the ones that are functional are:
	// 0  : default behavior.
	// 3  : speed up catchup by skipping necessary validations
	// 12 : perform all validation methods (normal and additional). These extra tests helps to verify the integrity of the compiled executable against
