Hi everyone,
I’m trying to run my own mining node using the instructions from https://github.com/mimblewimble/docs/wiki/How-to-mine-Grin and it seems to be working.
After two days with my RTX 2080Ti (I7-7700) I still have no block but I think it should take about 20 days with 1.6gps anyway. What worries me is that I have about 2-3% stale shares from my miner. Compared to using a mining pool this seems high. Is this normal when mining on your own node? Is this a problem of my node and could be solved with a better configuration?
The mining configuration has the “minimum_share_difficulty” parameter. From what I have read this would increase the difficulty of the jobs for the miners, reducing the number of shares the node has to process. My CPU load is low, so I guess the number of shares is not the problem. When should this parameter be increased? I noticed that grinmint and other pools have a difficulty of 4 while the default config is 1.
There is also the “chain_validation_mode” parameter. A full chain validation sounds good but what are the drawbacks when enabling “EveryBlock”?
Another question would be about the mining itself. From what I understood several accepted shares are needed before a new block is constructed and checked. Does this mean that when I mine with too few gps and thus too few accepted shares I will never be able to find a block since it takes too long and someone else will find a new block at the current height?
Thanks
