Mine where you actually own your rewards.
CWI-MKPool is the original MKPool MiningSystem under ChainWorksIndustries ownership. BTC and BCH SoloMining offer SV1, TLS and native SV2 with three VarDiff tiers per protocol, a 2% operator fee and 98% miner reward.
- No accounts
- No custody
- No hidden fees
- Direct coinbase reward
- BTC and BCH: TCP, TLS and native SV2
- Supports Bitaxe, Nerdaxe and more
- MiningRigRentals connections
Mining Services
BTC and BCH SoloMining are enabled. Other Coins and modes are disabled. Mine straight to your own wallet. No account, no custody, whole block rewards. You mine on your own against the whole network, and when you find a block the reward is yours, paid directly to your address in the block itself, minus a flat 2% operator fee. Nothing is shared with other miners, and the mining service never touches your coins. How often you find a block depends on your own hashrate versus the network, and luck.

Direct On-Chain Coinbase Payouts
CWI-MKPool runs on pure cryptographic trust, with no custodial accounts, no databases, and no registration forms. Your payout address is your username. The moment a block is solved, your reward is written straight into the coinbase transaction, so coins land in your wallet natively from the blockchain. We never hold, pool, or touch your funds.
- Direct Coinbase Payouts. Rewards are written straight into the block's coinbase output. No intermediary pool wallet, no withdrawal step, no payout delay.
- Address-Only Login. Your wallet address is your entire identity. No email, no password, nothing to phish or leak.
- Truly Non-Custodial. Your keys, your hashrate, your coins. Every share and payout stays verifiable on-chain.
Tailored for Bitaxe,
NerdAxe & ESP32 Solo Mining
Small solo miners are the heartbeat of Bitcoin's decentralization, so we built for them first. Our vardiff algorithm is tuned for low-hashrate hardware, keeping share rates healthy without ever flooding a tiny ESP32 buffer. Plug in, point at the mining service, and mine.
- Bitaxe Native Support. Works out of the box with Bitaxe Ultra, Supra, Gamma, and custom BM1397/BM1366 hardware.
- Smart ESP32 Vardiff. Difficulty adapts in real time to your device, preventing buffer overflows on small embedded controllers.
- Built for DIY Rigs. Perfect for NerdAxe, LilyGO T-Display, and any Stratum-compatible homebrew miner.
What CWI-MKPool is, in plain terms.
What is CWI-MKPool?
The original MKPool MiningSystem is owned and operated by ChainWorksIndustries. This live prototype currently offers Bitcoin and Bitcoin Cash SoloMining.
Which Coins and mining modes are available?
BTC SOLO and BCH SOLO. Other Coins, PPLNS and PROP remain disabled pending individual testing and verification.
How do I connect?
Use btc.mkpool.com for Bitcoin or bch.mkpool.com for Bitcoin Cash. Each offers TCP, TLS and native Stratum V2 Noise with LowDiff, MidDiff and HiDiff tiers. Use your own valid payout address for the selected chain, optionally with a worker name, and password x for automatic VarDiff. Confirm that you control the address before mining.
How are rewards allocated?
When your miner finds an accepted block, 98% of its coinbase value is allocated to your configured address and 2% to the operator, subject to whole-satoshi rounding. SoloMining does not provide regular shared payments. Coinbase rewards require maturity and remain subject to chain reorganizations.
Which connection tier should I choose?
LowDiff suits smaller home miners, MidDiff suits ASICs and farms, and HiDiff suits larger farms and rentals. The nominal VarDiff target is 18 shares per minute per connection, within each tier’s limits. Choose a protocol supported by your miner or rental service.
Is Anycast currently enabled?
Anycast is planned and remains disabled. Use the verified BTC and BCH connection pages. The original globe remains an illustration.
