Service transition · Action required

A stronger foundation.
A better place for your hashrate.

CWI-MKPool’s mining service and current website will close on 30 October 2026. Please move all miners to CWI-theMINE, our actively developed production MiningSystem.

  • A more robust Core. Extensive backend fixes, stricter payout verification and expanded health monitoring.
  • A cleaner experience. A simpler website and clearer interface, with continuing improvements.
  • More choice. BTC, BCH and ZEC SoloMining are live. More coins, PoolMining options and a dedicated third area for CWI-theMINE are planned.

CWI-theMINE fees

Lower fees. More for your mining.

About CWI-MKPool

The original MKPool MiningSystem, now owned and operated by ChainWorksIndustries as the CWI-MKPool public BTC and BCH SoloMining prototype.

The mission

CWI-MKPool is built around the simplest possible deal for miners: point your hardware at our stratum endpoint and get paid directly in the block's coinbase transaction. There are no accounts to create, no balances we hold on your behalf, and no withdrawal step. Your payout address is your only identifier.

How payouts work

When a worker on this mining service finds a block, the block reward is paid out directly in the coinbase transaction to the contributor (SOLO mining only). A flat 2% operator fee is taken from the same coinbase transaction to fund development and infrastructure. There are no other fees, no minimum, and no withdrawal step.

Roadmap

What is live today, and what we are building next.

CWI ownership and SoloMining

Live

ChainWorksIndustries acquired the private CWI-MKPool CodeBase, WebSite, API, Tools, documentation and mkpool.com Domain from Mecanik — Norbert Boros.

BTC and BCH: SV1, TLS and native SV2

Live

Three overlapping VarDiff tiers are live for each BTC and BCH protocol. Use your own valid mainnet payout address for the selected chain. The current fee remains 2%; the miner receives the 98% remainder.

Additional Coins and mining modes

Planned

Other Coins, pooled mining and Anycast remain disabled pending their individual development and verification. Dated progress is retained in the development blog.
