1  Bitcoin / Mining / Is it possible to mine bitcoin with cgminer in Regtest mode ? on: August 11, 2016, 08:01:03 AM
i JUST tried , but it seemed the answer was no. Am I wrong ?

mining rig:  Antminer U3
cgminer conf:  cgminer.exe --bmsc-options 115200:0.57 -o http://localhost:19011 -u admin2 -p 123 --bmsc-voltage 0800 --bmsc-freq 1286 --btc-address mvpZ5cDtbL32jRwL2F5JSgdKknP1GLcaP3

2  Alternate cryptocurrencies / Altcoin Discussion / Re: how to solve merged mining conflicts among coins with different block time on: August 09, 2016, 06:10:43 PM
I guess this topic fits better to the altcoin section.  What particular problem do you see with merge-mined coins that have different block times?  I see none.  The prev hash points to the previous block hash of the chain in question (Huntercoin in your example), just as always.  Why do you think it should be different?

Maybe  I got confused about parent block and bitcoin block.  I tried to understand,  a parent block is not eqaul to a bitcoin block,  In auxpow block,  the previous parent block hash points to the last parent block not bitcoin block.   I'm right ?

As we known,  nmc and bitcoin both have  block time of 10 minutes , what about  huntercoin (2 minutes) ? 
Are there any special in huntercoin (auxpow block) data structure,  for example  the prev_hash in parent block  header are all the same ?

Thanks. I just want to know the information about nodes connected.

Often see on blockchain.info But cannot get through bitcoind
