Contributions

Code contributions are very welcome and should be submitted as standard pull requests (PR) based on the dev branch.

Building on Debian/Ubuntu

git clone https://github.com/oliverw/miningcore
cd miningcore

Depending on your OS Version run either of these scripts:

./build-debian-11.sh

./build-ubuntu-20.04.sh

./build-ubuntu-21.04.sh

Building on Windows

Download and install the .NET 6 SDK

git clone https://github.com/oliverw/miningcore
cd miningcore
build-windows.bat

Building in Visual Studio

Install Visual Studio 2022. Visual Studio Community Edition is fine.
Open Miningcore.sln in Visual Studio

Building using Docker Engine

In case you don't want to install any dependencies then you can build the app using the official Microsoft .NET SDK Docker image.

git clone https://github.com/oliverw/miningcore
cd miningcore

Then build using Docker:

docker run --rm -v $(pwd):/app -w /app mcr.microsoft.com/dotnet/sdk:6.0 /bin/bash -c 'apt update && apt install libssl-dev pkg-config libboost-all-dev libsodium-dev build-essential cmake -y --no-install-recommends && cd src/Miningcore && dotnet publish -c Release --framework net6.0 -o /app/build/'

It will use a Linux container, you will build a Linux executable that will not run on Windows or macOS. You can use a runtime argument (-r) to specify the type of assets that you want to publish (if they don't match the SDK container). The following examples assume you want assets that match your host operating system, and use runtime arguments to ensure that.

For macOS:

docker run --rm -v $(pwd):/app -w /app mcr.microsoft.com/dotnet/sdk:6.0 /bin/bash -c 'apt update && apt install libssl-dev pkg-config libboost-all-dev libsodium-dev build-essential cmake -y --no-install-recommends && cd src/Miningcore && dotnet publish -c Release --framework net6.0 -o /app/build/ -r osx-x64 --self-contained false'

Building and Running Miningcore from a container

note - The build scripts optimize the build for the hardware platform the container is built on ( does it have avx for example). If you run this container on a platform that does NOT have the same architecture you could have unexplained crashes. YOU SHOULD BUILD THIS CONTAINER ON THE HOST YOU ARE GOING TO RUN THIS CONTAINER ON.

Commands to build container: docker build -t <your_dockerhubid>/miningcore:v73-foo .

The docker build assumes you are going to mount your config file in a volume mount. for example:

docker run -d \
    -p 4000:4000 \
    -p 4066:4066 \
    -p 4067:4067 \
    --name mc    \
    -v `pwd`/config_prod.json:/app/config.json \
    --restart=unless-stopped \
    <your_dockerhubid>/miningcore:v73-foo

For Windows using Linux container:

docker run --rm -v $(pwd):/app -w /app mcr.microsoft.com/dotnet/sdk:6.0 /bin/bash -c 'apt update && apt install libssl-dev pkg-config libboost-all-dev libsodium-dev build-essential cmake -y --no-install-recommends && cd src/Miningcore && dotnet publish -c Release --framework net6.0 -o /app/build/ -r win-x64 --self-contained false'

To delete used images and containers you can run after all:

docker system prune -af

Running Miningcore

Production OS

Windows is not a supported production environment. Only Linux is. Please do not file issues related to running a pool on Windows. Windows topics should be posted under discussions.

Running and developing Miningcore on Windows is of course supported.

Database setup

Miningcore currently requires PostgreSQL 10 or higher.

Run Postgres's psql tool:

sudo -u postgres psql

In psql execute:

CREATE ROLE miningcore WITH LOGIN ENCRYPTED PASSWORD 'your-secure-password';
CREATE DATABASE miningcore OWNER miningcore;

Quit psql with \q

Import the database schema:

sudo -u postgres psql -d miningcore -f miningcore/src/Miningcore/Persistence/Postgres/Scripts/createdb.sql

Advanced setup

If you are planning to run a Multipool-Cluster, the simple setup might not perform well enough under high load. In this case you are strongly advised to use PostgreSQL 11 or higher. After performing the steps outlined in the basic setup above, perform these additional steps:

WARNING: The following step will delete all recorded shares. Do NOT do this on a production pool unless you backup your shares table using pg_backup first!

sudo -u postgres psql -d miningcore -f miningcore/src/Miningcore/Persistence/Postgres/Scripts/createdb_postgresql_11_appendix.sql

After executing the command, your shares table is now a list-partitioned table which dramatically improves query performance, since almost all database operations Miningcore performs are scoped to a certain pool.

The following step needs to performed once for every new pool you add to your cluster. Be sure to replace all occurences of mypool1 in the statement below with the id of your pool from your Miningcore configuration file:

CREATE TABLE shares_mypool1 PARTITION OF shares FOR VALUES IN ('mypool1');

Once you have done this for all of your existing pools you should now restore your shares from backup.

Configuration

Create a configuration file config.json as described here.

Start the Pool

cd build
Miningcore -c config.json

Supported Currencies

Caveats

Monero

Monero's Wallet Daemon (monero-wallet-rpc) relies on HTTP digest authentication for authentication which is currently not supported by Miningcore. Therefore monero-wallet-rpc must be run with the --disable-rpc-login option. It is advisable to mitigate the resulting security risk by putting monero-wallet-rpc behind a reverse proxy like nginx with basic-authentication.
Miningcore utilizes RandomX's light-mode by default which consumes only 256 MB of memory per RandomX-VM. A modern (2021) era CPU will be able to handle ~ 50 shares per second in this mode.
If you are running into throughput problems on your pool you can either increase the number of RandomX virtual machines in light-mode by adding "randomXVmCount": x to your pool configuration where x is at maximum equal to the machine's number of processor cores. Alternatively you can activate fast-mode by adding "randomXFlagsAdd": "RANDOMX_FLAG_FULL_MEM" to the pool configuration. Fast mode increases performance by 10x but requires roughly 3 GB of RAM per RandomX-VM.

ZCash

Pools needs to be configured with both a t-addr and z-addr (new configuration property "z-address" of the pool configuration element)
First configured zcashd daemon needs to control both the t-addr and the z-addr (have the private key)
To increase the share processing throughput it is advisable to increase the maximum number of concurrent equihash solvers through the new configuration property "equihashMaxThreads" of the cluster configuration element. Increasing this value by one increases the peak memory consumption of the pool cluster by 1 GB.
Miners may use both t-addresses and z-addresses when connecting to the pool

Vertcoin

Be sure to copy the file verthash.dat from your vertcoin blockchain folder to your Miningcore server
In your Miningcore config file add this property to your vertcoin pool configuration: "vertHashDataFile": "/path/to/verthash.dat",

API

Miningcore comes with an integrated REST API. Please refer to this page for instructions: https://github.com/oliverw/miningcore/wiki/API

Running a production pool

A public production pool requires a web-frontend for your users to check their hashrate, earnings etc. Miningcore does not include such frontend but there are several community projects that can be used as starting point.

Once again, do not run a production pool on Windows! This is not a supported configuration.
