Arguments: 1. checklevel (numeric, optional, default=3, range=0-4) How thorough the block verification is: - level 0 reads the blocks from disk - level 1 verifies block validity - level 2 verifies undo data - level 3 checks disconnection of tip blocks - level 4 tries to reconnect the blocks - each level includes the checks of the previous levels 2. nblocks (numeric, optional, default=6, 0=all) The number of blocks to check. Result: true|false (boolean) Verification finished successfully. If false, check debug.log for reason.
