Is it possible to pre-mine next block when everyone is mining current block?
Let's say, if we need 1T hash power to mine (solo / pool) a block in 1 hour, then is it possible to run 1G hash miner for 1000 hours and then use this data as proof of work.
With 1G miner, I am essentially targeting n'th (x + 6000) block in future, hoping to solve it. I will broadcast it as soon as I get hash of n-1'th block.

You seem to be asking if you can mine block X+1 while the network is still working on block X.
The answer is no, you can't mine block X+1 until block X has been solved, as each block requires a hash of the previous block to be valid.
hash(block X) needs to start with (block X+1) mining, or just to broadcast mined (block X+1) ?! – vi.su. – 2013-04-12T01:31:59.943
can you please comment on my previous question. Thanks. – vi.su. – 2013-04-29T10:49:11.273
@vi.su. I'm not sure what you're asking exactly. Block X+1 requires a hash from a block X though, which means block X must have been solved already before mining of block X+1 can start. – Highly Irregular – 2013-04-29T19:50:49.257
thanks. I thought it is also possible to start mining x+1 block, even before block x is mined, and to broadcast x+1 block, We need block x hash (because block x hash is just part of block x+1, not included in the mining calculations). – vi.su. – 2013-04-30T01:33:33.917
1Does solving block X+1 if you solved (but did not broadcast) block X count as one of the approaches? – Stephen Gornick – 2013-04-10T09:25:38.747
