BC3 uses standard Bitcoin stratum (mining.subscribe / mining.notify / mining.submit). Plain TCP uses stratum+tcp://; SSL uses stratum+ssl://. Pool ping explained.

Configuration

Algorithmsha3t — triple SHA3-256 over the 80-byte block header. Stateless (no dataset, no hugepages benefit).
Protocolstandard Bitcoin stratum (mining.subscribe / mining.notify / mining.submit).
Walletany valid BC3 address: legacy P2PKH (1…), P2SH (3…) or bech32 (bc1q…). All accepted for payouts.
Workershort label per rig, e.g. rig01. Appended after a dot: ADDRESS.WORKER.
Passwordx.

Generic connection template (replace <MINER> with SRBMiner, suprminer or any other sha3t-capable miner, and YOUR_BC3_ADDRESS with your own address):

./<MINER> -a sha3t \
  -o stratum+tcp://bc3.suprnova.cc:7701 \
  -u YOUR_BC3_ADDRESS.rig01 \
  -p x

Exact flag names will vary between miners — the example above uses the widely-adopted cpuminer-style syntax (-a, -o, -u, -p). Consult your miner's documentation for its equivalents.

Platform Instructions

terminal

Linux — pick a miner

Two GPU miners support sha3t. Use SRBMiner-Multi for AMD/Intel/NVIDIA cards, or suprminer for NVIDIA only.

SRBMiner-Multi AMD NVIDIA Intel latest release →

tar xzf SRBMiner-Multi-*-Linux.tar.gz
cd SRBMiner-Multi-*
./SRBMiner-MULTI --algorithm sha3t \
  --pool bc3.suprnova.cc:7701 \
  --wallet YOUR_BC3_ADDRESS.rig01 \
  --password x

suprminer NVIDIA latest release →

chmod +x suprminer-neptune-*-linux-x86_64
./suprminer-neptune-*-linux-x86_64 -a sha3t \
  -o stratum+tcp://bc3.suprnova.cc:7701 \
  -u YOUR_BC3_ADDRESS.rig01 \
  -p x

Prefer encrypted stratum? Swap the URL for stratum+ssl://bc3.suprnova.cc:7704. Append .rig01 (any label) to your wallet to distinguish per-rig stats. Password can be anything (x is conventional).

window

Windows — pick a miner

Download the Windows build, extract, run from PowerShell or cmd.exe. Both miners support sha3t.

SRBMiner-Multi AMD NVIDIA Intel latest release →

SRBMiner-MULTI.exe --algorithm sha3t --pool bc3.suprnova.cc:7701 --wallet YOUR_BC3_ADDRESS.rig01 --password x

suprminer NVIDIA latest release →

suprminer.exe -a sha3t -o stratum+tcp://bc3.suprnova.cc:7701 -u YOUR_BC3_ADDRESS.rig01 -p x

Windows Defender will likely flag mining binaries on first run — that's normal; whitelist the folder if needed. Use stratum+ssl://bc3.suprnova.cc:7704 for TLS.

Hashrate rental (NiceHash, MRR)

Rental marketplaces (NiceHash, Mining Rig Rentals) do not yet list the sha3t algorithm.

Port 7705 is already tuned for the NiceHash session lifetime (higher starting difficulty, aggressive VarDiff) and will accept connections the moment a compatible seller appears. We will update this section with the exact algorithm slug and marketplace URL once a listing goes live.

In the meantime, running your own hardware against port 7701 is the only way to hash BC3.

Quick facts

BitcoinIII is a Bitcoin Core v29 fork with a swapped block-hash algorithm (sha3t, triple SHA3-256). 10-minute block target, 50 BC3 subsidy at genesis, halving every 210,000 blocks. No developer tax.
Your payout address is your BC3 wallet address — legacy P2PKH (1…), P2SH (3…) or bech32 (bc1q…) all work. Append .rig01 (any label) to distinguish per-rig stats on the dashboard.
sha3t is stateless — there is no dataset to allocate, so hugepages / MSR tweaks that RandomX or Ethash needed are not applicable here. Pick the port that matches your rig size (see the stratum table above).
