Hi everyone! I’m new to mining Grin, and I’m mining Grin-C29 on my laptop. I’ve installed grin, grin-wallet, and grin-miner, according to grin-miner, and my NVIDIA 4070 Ti is giving ~2.24 Kgps. But after an entire night of mining, I have 0 accepted, rejected, or stale shares. Additionally, grin-miner reports that the target share difficulty is always 1. What am I doing wrong?
Here’s my grin-server.toml:
# Generated Server Configuration File for Grin
#
# When running the grin executable without specifying any command line
# arguments, it will look for this file in two places, in the following
# order:
#
# -The working directory
# -[user home]/.grin

config_file_version = 2
