Welcome to solo.ckpool.org!

No frills, no fuss 2% fee anonymous solo bitcoin mining for everyone

No registration required, no payment schemes, no pool operator wallets.

This is a NOT-FOR-PROFIT pool; all care is given but no responsibility is taken in the event of an issue with the pool.

Note: This is NOT a pool despite its name; it is a service to allow miners to mine solo blocks as you cannot mine directly to a Bitcoin Core node.

Miners in Europe and Africa should use the sister pool: eusolo.ckpool.org

Graphical statistics:

Visit solostats.ckpool.org for graphical statistics.

Configuration:

Just point your miner to:

For miners that require a high difficulty, such as mining rentals, there is a special high diff port:

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

Example:

cgminer -o stratum+tcp://solo.ckpool.org:3333 -u 1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ.0 -p x

Or in your ASIC miner's configuration boxes:

Pool:solo.ckpool.org

Port:3333

Username:1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ.0

Password (ignored):x

If you enter an invalid address, you will be rejected.

Note that solo.ckpool.org supports both IPv4 and IPv6 transparently. If your network has a dual IPv4/IPv6 stack it will likely default to IPv6.

You may wish to find which is lower latency for you and specify one or the other directly:

Miners may wish to use the sister pool as a backup: eusolo.ckpool.org

Transaction selection transparency:

Solo.ckpool.org does not filter any transactions and uses default Bitcoin Core transaction selection. Live monitoring of the current transactions can be done at any time by examining the following URL:

solo.ckpool.org/pool.txns

This can also be used to monitor the likelihood of your personal transactions being mined in the next block at any pool.

As this uses a moderate amount of bandwidth, please minimize your usage of this to avoid the need to disable this service.

FAQ:

The most commonly asked question is why your mining statistics are not showing up under users. The reason for this is your mining hashrate is too low to be detected by the pool due to a minimum difficulty of 10,000 set. The pool will eventually pick up your shares and slowly adjust to suit your mining hardware.

If you are using client software that supports the client-diff option, you can set this to a lower value, with 1 being the minimum, but it has no influence on your chance of finding a block, as shares are cosmetic for feedback only here.

Hashrates below 1GH are not recommended to mine Bitcoin as it is unrealistic they will ever find a block. Feel free to try them as a learning experience or proof of concept, but it is highly recommended you don't thrash such devices and waste your time and energy.

CPU, GPU, and FPGA miners are never recommended for mining Bitcoin.

Nerdminers are demonstration toys only that simply waste bandwidth to the pool; please do not mine with them here.

Advantages over regular solo mining:

Mining at solo.ckpool.org avoids the overheads of running a full Bitcoin node that requires both great storage and bandwidth for optimal performance. Solo.ckpool.org is extensively connected to high-speed, low-latency Bitcoin nodes for rapid block change notification and

propagation. It also supports all stratum-mining-compatible ASIC miners with no registration required.

This allows you to easily mine to your own address without needing to rely upon payout systems or risking your rewards with pool operators.

Disadvantages compared to regular solo mining:

If your mining setup is already highly optimized with your own Bitcoin node, there is no advantage to using this service, and you will only pay a fee to support its maintenance.

There is also a small extra delay in communication, which means slightly less efficient mining. The loss is typically less than 0.5% but may vary depending on your setup and location.

However, you also pay a 2% fee on top of the transaction fees paid by Bitcoin, meaning a small portion of your mining reward will go towards maintaining this pool.
