Dcrpool is a stratum decred mining pool. It currently supports:

• Innosilicon D9 (default port: 5552, supported firmware: D9_20180602_094459.swu)
• Antminer DR3 (default port: 5553)
• Antminer DR5 (default port: 5554)
• Whatsminer D1 (default port: 5555)

The pool can be configured to mine in solo pool mode or as a publicly available mining pool. Solo pool mode represents a private mining pool operation where all connected miners to the pool are owned by the pool administrator. For this reason, mining rewards are left to accumulate at the specified address for the mining node. There isn't a need for payment processing in solo pool mining mode, it is disabled as a result.

In solo pool mining mode, miners only need to identify themselves when connecting to the pool. The miner's username, specifically the username sent in a mining.authorize message should be a unique name identifying the client.

The pool supports Pay Per Share (PPS) and Pay Per Last N Shares (PPLNS) payment schemes when configured for pool mining. With pool mining, mining clients connect to the pool, contribute work towards solving a block and claim shares for participation. When a block is found by the pool, portions of the mining reward due participating accounts are calculated based on claimed shares and the payment scheme used. The pool pays out the mining reward portions due each participating account when it matures.

In addition to identifying itself to the pool, each connecting miner has to specify the address its portion of the mining reward should be sent to when a block is found. For this reason, the mining client's username is a combination of the address mining rewards are paid to and its name, formatted as: address.name. This username format for pool mining is required. The pool uses the address provided in the username to create an account, all other connected miners with the same address set will contribute work to that account.

The user interface of the pool provides public access to statistics and pool account data. Users of the pool can access all payments, mined blocks by the account and also work contributed by clients of the account via the interface. The interface is only accessible via HTTPS and by default uses a self-signed certificate, served on port :8080. In production, particularly for pool mining, a certificate from an authority (CA) like letsencrypt is recommended. The user interface also provides pool administrators database backup functionality when needed.

Building or updating from source requires the following build dependencies:

• Go 1.12 or 1.13

  Installation instructions can be found here: https://golang.org/doc/install. It is recommended to add $GOPATH/bin to your PATH at this point.

• Git

  Installation instructions can be found at https://git-scm.com or https://gitforwindows.org.

To build and install from a checked-out repo or a copy of the latest release, run go install . ./cmd/... in the root directory. Some notes:

• Set the GO111MODULE=on environment variable.

• The dcrpool executable will be installed to $GOPATH/bin. GOPATH defaults to $HOME/go (or %USERPROFILE%\go on Windows) if unset.

git clone https://github.com/decred/dcrpool.git
cd dcrpool 
go install 
dcrpool --configfile=path/to/config.conf 

Dcrpool requires dcrd and dcrwallet when configured as a mining pool, it only requires dcrd when configured as a solo pool. Deploying the user interface requires copying the dcrpool/gui/assets folder from source to a reachable location and updating the gui directory (--guidir) of the configuration. Currently only single instance deployments are supported, support for distributed deployments will be implemented in the future.

Refer to config descriptions for more detail.

In mining pool mode the ideal wallet setup is to have two wallet accounts, the pool account and the fee account, for the mining pool. This account structure separates revenue earned from pool operations from mining rewards gotten on behalf of participating clients. The pool account's purpose is to receive mining rewards of the pool. The address generated from it should be the mining address (--miningaddress) of the mining node. The fee account's purpose is to receive pool fees of the mining pool. The address generated from it should be the address set as the pool fee address (--poolfeeaddrs) of the mining pool.

The project has a configurable tmux mining harness and a cpu miner for testing.

To run the mining harness:

cd dcrpool/cmd/miner 
go install
cd ../..
./harness.sh 

Dcrpool is ideal for miners running medium-to-large mining operations. The revenue generated from mining blocks as well as not paying pool fees to a publicly available mining pool in the process should be enough to offset the cost of running a pool. It will most likely not be cost effective to run dcrpool for a small mining operation, the better option here would be using
a public mining pool instead.

For people looking to setup a publicly available mining pool, dcrpool's well-documented configuration and simple setup process also make it a great option.
