Miner Configuration

Get Started

Algorithm

SHA256d (BitcoinII)

Use a SHA256d-compatible miner. Examples below include Windows-friendly options.

Quick Start (Windows)

cpuminer-opt

Download: cpuminer-opt Releases
Create a start.bat with the following (edit wallet + port if needed): 

cpuminer.exe -a sha256d ^
  -o stratum+tcp://stratum.darkfibermines.com:3333 ^
  -u YOUR_BTCII_WALLET.WorkerName ^
  -p d=8
  • Replace 3333 with your pool’s Stratum port (see “Pool Configuration” table).
  • Use a valid BitcoinII wallet address; add a dot + worker label (e.g., .Rig01).
  • d=8 sets low difficulty so you see accepted shares quickly on a normal PC.

Alternative (Windows)

BFGMiner / CGMiner

BFGMiner: Releases
bfgminer.exe -o stratum+tcp://stratum.darkfibermines.com:3333 -u YOUR_BTCII_WALLET.WorkerName -p d=8

CGMiner (SHA256d builds): similar syntax:
cgminer.exe --url stratum+tcp://stratum.darkfibermines.com:3333 --userpass YOUR_BTCII_WALLET.WorkerName:d=8

ASIC UI Example

Antminer (SHA256)
  • Pool URL: stratum+tcp://stratum.darkfibermines.com:3333
  • Worker: YOUR_BTCII_WALLET.WorkerName
  • Password: d=64 (or d=32 for smaller devices)

Increase d= on high-hashrate devices to reduce submit frequency; decrease it on very low-hashrate tests.

NiceHash

Hashpower to BC2

If your pool has a NiceHash-compatible port, point NiceHash to:
stratum+tcp://stratum.darkfibermines.com:<nicehash-port>
Username: YOUR_BTCII_WALLET.WorkerName   Password: x or d=256
Check the “Pool Configuration” table for the exact NiceHash port if enabled.

Verify Connection

What success looks like
  • Your miner shows accepted shares within a minute or two.
  • This dashboard shows your worker under Miners with hashrate and shares.
  • API check: /api/pools → pick your pool ID → /api/pools/<id>/miners.
