bitcryptic/ckpool-solo repository overview

⁠ckpool-solo for Unraid

Self-hosted Bitcoin solo mining — built by BitCryptic.

Point your ASICs at your own Bitcoin Core node and keep 100% of the block reward. No pool fees, no middleman, no custodian. This image runs ckpool in -B BTCSOLO mode, built from source against the official Bitbucket repository by Con Kolivas.

⁠How It Works

ckpool acts as a lightweight stratum server that bridges your mining hardware to your local Bitcoin Core node. When your miner finds a valid block, it is submitted directly via your own node — no third party involved.

⁠Requirements

• A fully synced Bitcoin Core node with RPC enabled (on the same Docker network or reachable via LAN)
• At least one miner configured for stratum (stratum+tcp://your-server:3333)
• A Bitcoin address to receive block rewards

⁠Configuration

ckpool reads from a config file mounted at /etc/ckpool/ckpool.conf. A minimal example:

{
  "btcd": [
    {
      "url": "bitcoincore:8332",
      "auth": "yourrpcuser",
      "pass": "yourrpcpassword"
    }
  ],
  "btcaddress": "bc1qyouraddresshere",
  "btcsig": "/mined by BitCryptic/",
  "blockpoll": 500,
  "nonce1length": 4,
  "nonce2length": 8,
  "update_interval": 30,
  "version_mask": "1fffe000",
  "mindiff": 512,
  "startdiff": 2048,
  "logdir": "/var/log/ckpool"
}

Point your miners at stratum+tcp://your-unraid-ip:3333 with your Bitcoin address as the username and any string as the password.

⁠Unraid Setup

Add the CA template directly:

Or search ckpool-solo in Community Applications once listed.

⁠Realistic Expectations

Solo mining is a lottery. With two Bitmain S9s (~28 TH/s combined) at current network difficulty, the statistical average time to find a block is measured in decades. This is for hobbyists who want the experience of running their own mining infrastructure and understand the odds.

The point is sovereignty, not income.
