Begin by running a Start9 server (you may also be able to do this on Ubuntu, but I’ve not played with that). Once your server is running, install Bitcoin Knots and download the BTC blockchain. Then install Datum Gateway, which is what you’ll config to begin constructing your own blocks. You’ll also want to install Core Lightning and setup a Lightning node if you want to collect your share from the pool over Lightning rather than waiting to accumulate enough sats to be worthwhile to withdraw on-chain.
