Hi. Thats rampa from manicminer.in
How to know i am in the good chain?
I downloaded the github source. my actuakl block number is 27789. but diff is really low. 3.65099479,
Is this correct?
You are on the wrong chain. You will have to delete the following in your .catcoin directory, and then re-sync:
blocks
chainstate
peers.dat
