Hi, I'm a newbie at mining, I have never mined any coins or helped a pool with my computational power, I just know the basics of how mining works. Some months ago I forked bitcoin core and
wrote a guide of how to do it too, because I find it really interesting when you implement an idea
(that can be implemented). Although, the action is far from the theory. I found a lot of difficulties on my way.
I've solved some blocks on my forked Bitcoin Core, but I want to switch to cpuminer, since it's better to compute on the command line than on a UI. This is what I execute:
minerd --user rpcuser --pass 111111 --url http://127.0.0.1:8333/ --threads 4 --coinbase-addr 3B9dSAqGNSyPasdSrwbJZ2rLSgPmyt8bQQ --coinbase-sig "my test coins" -a sha256d -D
And this is what I get:
It has returned other errors on my forked Bitcoin Core, but I've ran it, above, on pruned Bitcoin Core (that follows the original bitcoin chain) and right now I get this. What am I doing wrong?
