I built an instance of ckpool and connected a 1.15 TH/s miner to it.  I mined 7 blocks in 8 hours.  This was configured as a standalone miner, so it was not suitable as a mining pool with many users.

I identified a configuration problem that created difficulties at block 58414.  I have pushed that problem back to block  58463.

The database support, ckdb, did not build effortlessly so I can't bring up multi-user support at the moment.
