I have a few asic blades 13 GHs and I am farming BTC on slash pool via stratum. How to change and what inside stratum to make those asics farm terarcoin on any one pool for TRC?
Stratum is dependent on the pool you are operating with. First you need to find a pool that supports terracoin, a short list can be found at terracon.org.
Once you decide on a pool, read their "Help" section to find the server settings required. I works exactly the same as bitcoin, you will enter a server address, a connection port, a username and a password.
Assuming you are using cgminer the parameters will look something like this:
cgminer -o http://pool:port -u username -p password
But plug in the values given from the pool. Welcome to Stack Exchange and good luck!
