Stratum, workers and variable difficulty.

These concepts are the same across every pool on Nexthash. Exact addresses and ports differ per pool — each one publishes its own on its "Mine" page.

The Stratum connection

Almost every pool speaks the Stratum protocol: your miner opens one TCP connection to the pool and submits shares over it. A typical connection looks like this:

For example, on Korsh: stratum+tcp://korsh.xyz:3333, username YOUR_KORSH_ADDRESS.rig1.

Worker names

The part after the dot in the username (.rig1, .laptop) is a free-form label, not a separate account. It lets a pool's dashboard tell your machines apart when the same address mines from more than one of them; it does not affect your rewards.

Variable difficulty

Pools adjust the difficulty of the shares your miner has to find so that you submit roughly one every few seconds, whether your hardware is a laptop core or a large server. A higher hashrate gets a higher difficulty automatically, so nothing needs to be configured by hand.

If shares are rejected

This is almost always a mismatch, not a bug: the wrong algorithm parameters, the wrong port, or a stale miner build. Check that your miner is built for that pool's exact algorithm and parameters, and that you can reach the Stratum port before asking for help.
