no, i can`t use this command unsuported in mining. Only eth_getWork and eth_submitWork – Taras Endick Jun 23 '16 at 10:49

@TarasEndick maybe edit your question and add some more details why you are limited to these calls. – q9f Jun 24 '16 at 09:07
I'm writing a miner , which connects to the pool. And the pool does not recognize such a command eth_blockNumber. For mining need only eth_getWork and eth_submitWork. I can not understand how I get the number of the block using only these commands . – Taras Endick Jun 24 '16 at 12:54
