Created genesis block and set up node. How to mine? Everything seems to be going well creating my altcoin for fun. I forked the BlackCoin source on Ubuntu, successfully mined a genesis block, recompiled. I bought a droplet over on digitalocean running Ubuntu 12.04, compiled my *coind from source, and ran it.

I know that worked because my *coin-qt on my local computer had 0 connections before, now it has 1, and my *coind getconnectioncount on my droplet reports 1 connection.

Here is my problem, my client *coin-qt says there are 80000 blocks remaining. Of course, it is stuck on block 0.

How can I fix this and start mining?
If it's predetermined that 80,000 blocks remain, it sounds like you haven't cleared out the checkpoints.

It's been awhile since I looked at anything other than Ripple or Nxt, but you should be able to find the checkpoints by simply searching for "checkpoint" in the code or the assert()s.

Also, to keep yourself from interfering with the original BlackCoin, you might want to use another port.
