What does mining on Parasite Pool pay?

When the pool finds a block, the worker that found it takes a fixed 1 BTC and leaves the split. The rest of the reward (~2.125 BTC plus block fees) is divided among everyone else, proportional to work accumulated since the last block. You get paid on every block the pool finds, not only when 'you win', with no pool fee and payouts from 10 satoshis.

It's the round rate: the split amount divided by the work that enters the split, per billion work units. Watch the denominator: it is not total round work, it is total minus the finder's work (they already took 1 BTC). Ignoring that understates payout by 4% to 8%. The rate is the same for everyone in the round, so your payment is your work (in billions) times that rate, whether you get paid on-chain or over Lightning.

Amounts already paid are exact and verifiable on-chain. 'Next block' is an estimate for a specific reason: nobody knows who will close the block yet, and the winner's slice leaves the split. That only pushes the rate up, never down, so the estimate has a floor. We use the expected winner slice (proportional to each person's work) and the shown range covers the rest. It also doesn't balloon while you wait: as everyone's work grows together, your slice stays stable.

Use Manual mode: enter your hashrate (for average earning rate) and, if you want, the accumulated work from your Parasite dashboard (for the next block). Because the round rate is the same for everyone, the result holds whether you get paid on-chain or over Lightning.
