What it returns

The blocks one address produced — as a validator, or as the block builder named as fee recipient — newest first, 50 a page, each with its time and what the producer earned for it. An address that never produced a block answers an empty list. nextPage is null on the last page; pages go no deeper than 200 (the newest 10000 blocks).
