This article is about the solo mining pool. For other uses, see Ckpool (disambiguation).


solo.ckpool.org is a solo mining pool implementation without the need to setup a local bitcoind.

solo.ckpool was started on the 31. August 2014 [1]. For developers there is also a testnet implementation available.

Pool code created and operated by Con Kolivas, creator of cgminer and ckpool.

Servers to use

  • Stratum - Use for ALL stratum capable Bitcoin mining software
stratum+tcp://solo.ckpool.org:3333
stratum+tcp://solo.ckpool.org:443

Miners closer to Europe please use one of:

stratum+tcp://de.ckpool.org:3333
stratum+tcp://de.ckpool.org:443

If you use an incompatible rental service that refuses to work on port 3333 try the following:

stratum+tcp://solo.ckpool.org:3334

If you have an asicminer tube/prisma, you can use a custom port 3335 (only accepts usernames without worker extensions) eg:

stratum+tcp://solo.ckpool.org:3335

Set your username to your btcaddress with any or even no worker extension, and any password.


stratum+tcp://testnet.ckpool.org:3333

Note this is mining worthless testnet coins only! Also, you must be using a testnet bitcoin address on this edition.

Reward distribution

  • If you find a block, 99% of the 12.5 BTC + transaction fees get generated directly at your bitcoin address.
  • 1% goes to the operator to operate the pool and contribute to further ckpool code development.


For testnet:

  • If you find a block, 100% of the testnet coins + transaction fees get generated directly at your bitcoin address.

Extra features

  • No overheads of running a full bitcoin node
  • Connected to high speed low latency bitcoin nodes for rapid block change notification and propagation.
  • No transaction-free blocks due to the ultra-scaleable code which has miners on both new blocks and transactions concurrently.
  • No registration required, no payment schemes, no pool operator wallets
  • The miner remains anonymous apart from his BTC address.
