Connect to a Pool ​

This guide points a running Mujina miner at a Stratum v1 pool. It assumes you can already start the miner; if not, take the tutorial first.

Configure the pool connection ​

Set the pool URL and your worker credentials, then start the daemon:

bash
MUJINA_POOL_URL="stratum+tcp://pool.example.com:3333" \
MUJINA_POOL_USER="your-address.worker" \
MUJINA_POOL_PASS="x" \
  cargo run --bin mujina-minerd
  • MUJINA_POOL_URL selects the Stratum v1 job source. Without it, the miner uses its built-in dummy source.
  • MUJINA_POOL_USER is the worker name your pool expects, typically a payout address with a worker suffix. Set it: the default is a shared testing name.
  • MUJINA_POOL_PASS is the worker password. Most pools ignore it; the default is x.

Combine these with whatever backend you mine on: a USB board needs nothing more, and a CPU-only run adds MUJINA_CPUMINER_THREADS and MUJINA_USB_DISABLE as in the tutorial.

The miner negotiates version rolling with the pool automatically.

Verify shares reach the pool ​

Watch the log for the pool connection and the periodic status line:

INFO  scheduler: Mining status.
      uptime=120s, hashrate=..., shares=3

A rising shares count means the pool is accepting your work. Check the pool's dashboard to confirm it sees the worker.

Test submission at CPU speed ​

Pools set share difficulty for ASIC-speed miners, so a CPU would wait days to find a single share. To exercise the submission path anyway, force a share rate:

bash
MUJINA_CPUMINER_THREADS=2 \
MUJINA_USB_DISABLE=1 \
MUJINA_POOL_URL="stratum+tcp://pool.example.com:3333" \
MUJINA_POOL_USER="your-address.worker" \
MUJINA_POOL_FORCED_RATE=6 \
  cargo run --bin mujina-minerd

MUJINA_POOL_FORCED_RATE is a target in shares per minute; 6 targets one share every ten seconds. The miner lowers its local share threshold to hit the rate, but the pool still applies real difficulty, so expect it to reject these shares as below difficulty. That is the point: you are verifying connectivity and the submission flow, not earning rewards.
