💡 WHAT IS PPS?

PPS guarantees you earn BC2 for every share you submit — no luck needed. No waiting for blocks. Your earnings are predictable and paid every hour.

⚠ Minimum Payout: 0.01 BC2 — Payouts are processed every hour. Balances below 0.01 BC2 will accumulate until the threshold is met.

How it works: Every valid share has a mathematical value based on network difficulty. The pool pays you for that value regardless of whether blocks are found.

Your BC2/day = (1e12 × 86400) / (net_diff × 2³²) × 50 BC2 × 0.99 At current network difficulty (38.02 G), 1% fee: 1 TH/s → ~0.0262 BC2/day (≈ 0.786 BC2/month) 100 TH/s → ~2.62 BC2/day (≈ 78.6 BC2/month) 1 PH/s → ~26.19 BC2/day (≈ 786 BC2/month) Verifiable: this is the same formula /api/stats uses to publish 0.026193 BC2/TH/day.

⚠️ WHY PPS?

The pool takes ALL the risk — you take none.

☢ Variance absorption — When the pool goes unlucky and doesn't find blocks for hours, we still pay you from our BC2 bankroll.

☢ Infrastructure — Dedicated servers in Ashburn VA, 24/7 uptime, zero stales, fast propagation.

☢ Supporting BC2 — We run this to support the BitcoinII network and give small miners a fair chance at earning BC2 without massive hashpower.

Solo = you gamble. PPS = guaranteed income. The extra 1% is your insurance premium.

HOW NATIVE PPLNS WORKS

► Uses CapStash native difficulty — accurate hashrate reporting
► All miners contribute shares to find a block together
► When a block is found, the reward is split based on your share contribution
► PPLNS uses a window of the last N shares to calculate your payout
► 1% pool fee deducted, remainder split proportionally
► Payouts sent automatically after 100 block confirmations
► For miners using: DankMiner v1.2.9+, BaraCUDA, or any CAP-native-diff miner

HOW DIFFICULTY WORKS HERE
Every port runs automatic difficulty (vardiff). Your first shares arrive at the port's start diff; within seconds the pool measures your real hashrate and sets your personal optimal difficulty — roughly one share every 3 seconds. Nothing to configure for normal use.
Manual control (optional): set your password to d=NUMBER to pin a starting/minimum difficulty, e.g. password d=500000. Also accepts diff=NUMBER. Standard mining.suggest_difficulty is honored too. This works on every port.
RENTING HASHRATE TO CAPSPOOL
⚡ NiceHash: point your order at port 3334 (solo) or 3336 (PPS). The port natively satisfies NiceHash's minimum-difficulty validation — no password needed.
⚡ Braiins Hashpower Market: same ports, works out of the box.
⚡ MiningRigRentals: MRR rents individual machines, usually under 1 PH/s. Use the ASIC port 3333/3335 for a regular-ASIC rental — it starts at the right difficulty for a single machine. For multi-PH MRR rentals use 3334/3336. If MRR shows low/zero hashrate, set the rental's pool password to d=65536 (single ASIC).
⚡ Huge bursts (100 PH+): 3334/3336 auto-scale — difficulty retargets within ~1 second of your first shares.
TROUBLESHOOTING
⚠ "Pool difficulty too low" (NiceHash): you're on the wrong port — use 3334/3336.
⚠ Rental shows low or spiky hashrate: difficulty too high for the machine size. Move a single-machine rental to 3333/3335, or set password d= per above.
⚠ Small miner shows no shares: anything below ~50 GH/s is below the small-port floor (diff 64); shares will be very rare by nature.
⚠ The pool never requires a password for payout — your address in the username is your identity.
