IV. Real world scenario
	-----------------------
	NiceHash server sends following job to miner:
	{"jsonrpc":"2.0","method":"job","params":{"blob":
	"0100f2fbf1ae05e778512836d3268c95b53004002f8bf0b4e591dd6c903e3620
	12b60a6eaf64cc0000003026f3436334364896a4dce0864798a16a137b9b5dc47
	a39f00a3a75077e8f14d102","job_id":"333972526853904",
	"target":"711b0d00"}}
	In this case; inside blob, 4 bytes of "00000000" are replaced with
	"000000030" by NiceHash. NiceHash gives miner byte "03".
	Miner sends found share:
	{"method": "submit", "params": {"id": "843393400195054", "job_id":
	"333972526853904", "nonce": "95565503", "result":
	"1b3f259aafb85c553198c2ad92392e816a8c030ac84305b89c932c8723bd0800"},
	"id":4}
	Nonce ends with byte "03" which is correct. Any other last byte
	of nonce would cause share above target.

I not understand. Why in json 4 bytes is 00 00 00 30. Next you wrote 00 00 00 030. 030? Where you take that? In first json nicehash byte is 30, not 03. Pleas explain.

It's not clear to me as well.
