Official BTC-K mining access
Updated 22 October 2026.
Both SOLO addresses use Seed-A as the sole mining backend. Seed-B forwards connections to Seed-A and does not mine independently. Independent node failover is disabled pending chain reconciliation. If Seed-A is unavailable, both entries pause mining to avoid competing branches. PPLNS reopening remains pending; Seed-B has no PPLNS endpoint.
| Mode | Seed-B — SOLO access relay | Seed-A — sole mining backend | Initial tier |
|---|---|---|---|
| PPLNS | Not provided | stratum+tcp://185.130.45.240:3332Reopening pending | Shared VarDiff; ASIC bootstrap 128 |
| SOLO | stratum+tcp://199.19.76.74:3333 | stratum+tcp://185.130.45.240:3333 | Below 1 TH/s; base difficulty 128 |
| SOLO | stratum+tcp://199.19.76.74:3334 | stratum+tcp://185.130.45.240:3334 | Typically 1–3 TH/s; base difficulty 4096 |
| SOLO | stratum+tcp://199.19.76.74:3335 | stratum+tcp://185.130.45.240:3335 | Typically 6–10 TH/s; base difficulty 16384 |
| SOLO | stratum+tcp://199.19.76.74:3336 | stratum+tcp://185.130.45.240:3336 | Typically 20–100+ TH/s; base difficulty 65536 |
The domain pool.bitcoin-k.com points to Seed-A; it is not an independent backup. A historical domain long-connection issue remains under investigation. The two IP entries are separate access paths to one mining backend.
Choose a mode and difficulty tier
SOLO ordinary block income goes directly to the finder under the published fee-block policy. PPLNS allocates ordinary income by accepted share difficulty over a rolling 10,000-share window. It reduces individual block variance without guaranteeing income. Both modes must remain visible regardless of hashrate.
Tier ranges guide initial share frequency, not admission. For intermediate rates, start with the adjacent lower tier and observe accepted shares. VarDiff then adjusts. The node target and ASIC firmware floor may override initial tiers. A higher port does not improve reward probability. 1 TH/s = 1,000 GH/s.
Configure both SOLO servers
- In the IceRiver or Antminer pool settings, set Pool 1 to
stratum+tcp://199.19.76.74:3333(Seed-B). - Set Pool 2 to
stratum+tcp://185.130.45.240:3333(Seed-A; direct backend). Choose the same difficulty-tier port on both servers. - Use the same payout address and worker name in both slots, with password
x. Select priority/failover mode if supported, then save. Check accepted shares on the active server.
Keep both access entries configured. Automatic reconnection depends on firmware and fault detection and may briefly interrupt mining. Both entries use Seed-A; independent node failover remains disabled until synchronization and takeover are verified.
Keep the reward mode consistent. Seed-B has no PPLNS endpoint on port 3332. Do not configure SOLO as an automatic backup for PPLNS unless you deliberately accept the different reward mode.
Miner settings
Worker: <your BTC-K wallet address>.<unique machine name>. Password: x. Never enter a wallet unlock password. The port selects mode. Keep failover endpoints in the same mode unless deliberately switching.
Fees and payment status
The configured fee schedule is 5% on launch days 1–7, 3% on days 8–30 and 1% afterward. PPLNS is configured for a 5 BTC-K minimum, UTC batches at 00:00/06:00/12:00/18:00, mature-input filtering and six-confirmation settlement. These are configured payment rules; PPLNS reopening remains pending during this incident. Pending receipts are checked every30 seconds when the payment service is operational. Safety holds or incomplete treasury checkpoints prevent new payments; sub-threshold balances remain recorded.
HTTP monitoring ports 3337/3338 are loopback-only; node RPC 16110 and P2P 16111 are not mining ports.
