⁠Introduction

Monero is a private, secure, untraceable, decentralised digital currency. You are your bank, you control your funds, and nobody can trace your transfers unless you allow them to do so.

Privacy: Monero uses a cryptographically sound system to allow you to send and receive funds without your transactions being easily revealed on the blockchain (the ledger of transactions that everyone has). This ensures that your purchases, receipts, and all transfers remain absolutely private by default.

Security: Using the power of a distributed peer-to-peer consensus network, every transaction on the network is cryptographically secured. Individual wallets have a 25 word mnemonic seed that is only displayed once, and can be written down to backup the wallet. Wallet files are encrypted with a passphrase to ensure they are useless if stolen.

Untraceability: By taking advantage of ring signatures, a special property of a certain type of cryptography, Monero is able to ensure that transactions are not only untraceable, but have an optional measure of ambiguity that ensures that transactions cannot easily be tied back to an individual user or computer.

⁠About this project

This is the core implementation of Monero. It is open source and completely free to use without restrictions, except for those specified in the license agreement below. There are no restrictions on anyone creating an alternative implementation of Monero that uses the protocol and network in a compatible manner.

As with many development projects, the repository on Github is considered to be the "staging" area for the latest changes. Before changes are merged into that branch on the main repository, they are tested by individual developers in their own branches, submitted as a pull request, and then subsequently tested by contributors who focus on testing and code reviews. That having been said, the repository should be carefully considered before using it in a production environment, unless there is a patch in the repository for a particular show-stopping issue you are experiencing. It is generally a better idea to use a tagged release for stability.

Anyone is welcome to contribute to Monero's codebase! If you have a fix or code change, feel free to submit it as a pull request directly to the "master" branch. In cases where the change is relatively small or does not affect other parts of the codebase it may be merged in immediately by any one of the collaborators. On the other hand, if the change is particularly large or complex, it is expected that it will be discussed at length either well in advance of the pull request being submitted, or even directly on the pull request.

⁠Scheduled software upgrades

Monero uses a fixed-schedule software upgrade (hard fork) mechanism to implement new features. This means that users of Monero (end users and service providers) should run current versions and upgrade their software on a regular schedule. Software upgrades occur during the months of April and October. The required software for these upgrades will be available prior to the scheduled date. Please check the repository prior to this date for the proper Monero software version. Below is the historical schedule and the projected schedule for the next upgrade. Dates are provided in the format YYYY-MM-DD.

X's indicate that these details have not been determined as of commit date.

⁠Release staging schedule and protocol

Approximately three months prior to a scheduled software upgrade, a branch from Master will be created with the new release version tag. Pull requests that address bugs should then be made to both Master and the new release branch. Pull requests that require extensive review and testing (generally, optimizations and new features) should not be made to the release branch.

⁠Installing Monero from a package

Packages are available for

• Ubuntu and snap supported⁠ systems, via a community contributed build.

  snap install monero --beta

Installing a snap is very quick. Snaps are secure. They are isolated with all of their dependencies. Snaps also auto update when a new version is released.

• Arch Linux (via AUR⁠):

  • Stable release: monero⁠
  • Bleeding edge: monero-git⁠

• Void Linux:

  xbps-install -S monero

• GuixSD

    guix package -i monero
  

  Copy

• OS X via Homebrew⁠

    brew tap sammy007/cryptonight
    brew install monero --build-from-source
  

  Copy

• Docker

    # Build using all available cores
    docker build -t monero .
  

  Copy

• GitHub: https://github.com/electronero/⁠

⁠Compiling Electronero from source

⁠Dependencies

The following table summarizes the tools and libraries required to build. A few of the libraries are also included in this repository (marked as "Vendored"). By default, the build uses the library installed on the system, and ignores the vendored sources. However, if no library is found installed on the system, then the vendored source will be built and used. The vendored sources are also used for statically-linked builds because distribution packages often include only shared library binaries (.so) but not static library archives (.a).

[^] On Debian/Ubuntu libgtest-dev only includes sources and headers. You must build the library binary manually. This can be done with the following command sudo apt-get install libgtest-dev && cd /usr/src/gtest && sudo cmake . && sudo make && sudo mv libg* /usr/lib/

⁠Cloning the repository

Clone recursively to pull-in needed submodule(s):

$ git clone --recursive https://github.com/electronero/electronero

If you already have a repo cloned, initialize and update:

$ cd electronero && git submodule init && git submodule update

⁠Build instructions

Electronero uses the CMake build system and a top-level Makefile⁠ that invokes cmake commands as needed.

⁠On Linux and OS X

• Install the dependencies

• Change to the root of the source code directory and build:

    cd electronero
    make
  

  Copy

  Optional: If your machine has several cores and enough memory, enable parallel build by running make -j<number of threads> instead of make. For this to be worthwhile, the machine should have one core and about 2GB of RAM available per thread.

  Note: If cmake can not find zmq.hpp file on OS X, installing zmq.hpp from https://github.com/zeromq/cppzmq⁠ to /usr/local/include should fix that error.

• The resulting executables can be found in build/release/bin

• Add PATH="$PATH:$HOME/electronero/build/release/bin" to .profile

• Run Electronero with electronerod --detach

• Optional: build and run the test suite to verify the binaries:

    make release-test
  

  Copy

  NOTE: core_tests test may take a few hours to complete.

• Optional: to build binaries suitable for debugging:

     make debug
  

  Copy

• Optional: to build statically-linked binaries:

     make release-static
  

  Copy

Dependencies need to be built with -fPIC. Static libraries usually aren't, so you may have to build them yourself with -fPIC. Refer to their documentation for how to build them.

• Optional: build documentation in doc/html (omit HAVE_DOT=YES if graphviz is not installed):

    HAVE_DOT=YES doxygen Doxyfile
  

  Copy

⁠On the Raspberry Pi

Tested on a Raspberry Pi Zero with a clean install of minimal Raspbian Stretch (2017-09-07 or later) from https://www.raspberrypi.org/downloads/raspbian/⁠. If you are using Raspian Jessie, please see note in the following section⁠.

• apt-get update && apt-get upgrade to install all of the latest software

• Install the dependencies for Electronero from the 'Debian' column in the table above.

• Increase the system swap size:

	sudo /etc/init.d/dphys-swapfile stop  
	sudo nano /etc/dphys-swapfile  
	CONF_SWAPSIZE=1024  
	sudo /etc/init.d/dphys-swapfile start  

• Clone electronero and checkout most recent release version:

        git clone https://github.com/electronero/electronero.git
	cd electronero
	git checkout tags/v0.11.1.0

• Build:

        make release

• Wait 4-6 hours

• The resulting executables can be found in build/release/bin

• Add PATH="$PATH:$HOME/electronero/build/release/bin" to .profile

• Run Electronero with electronero --detach

• You may wish to reduce the size of the swap file after the build has finished, and delete the boost directory from your home directory

⁠Note for Raspbian Jessie users:

If you are using the older Raspbian Jessie image, compiling Electronero is a bit more complicated. The version of Boost available in the Debian Jessie repositories is too old to use with Electronero, and thus you must compile a newer version yourself. The following explains the extra steps, and has been tested on a Raspberry Pi 2 with a clean install of minimal Raspbian Jessie.

• As before, apt-get update && apt-get upgrade to install all of the latest software, and increase the system swap size

	sudo /etc/init.d/dphys-swapfile stop  
	sudo nano /etc/dphys-swapfile  
	CONF_SWAPSIZE=1024  
	sudo /etc/init.d/dphys-swapfile start  

• Then, install the dependencies for Electronero except libunwind and libboost-all-dev

• Install the latest version of boost (this may first require invoking apt-get remove --purge libboost* to remove a previous version if you're not using a clean install):

	cd  
	wget https://sourceforge.net/projects/boost/files/boost/1.64.0/boost_1_64_0.tar.bz2  
	tar xvfo boost_1_64_0.tar.bz2  
	cd boost_1_64_0  
	./bootstrap.sh  
	sudo ./b2  

	sudo ./bjam install

• From here, follow the general Raspberry Pi instructions⁠ from the "Clone Electronero and checkout most recent release version" step.

⁠On Windows:

Binaries for Windows are built on Windows using the MinGW toolchain within MSYS2 environment⁠. The MSYS2 environment emulates a POSIX system. The toolchain runs within the environment and cross-compiles binaries that can run outside of the environment as a regular Windows application.

Preparing the build environment

• Download and install the MSYS2 installer⁠, either the 64-bit or the 32-bit package, depending on your system.

• Open the MSYS shell via the MSYS2 Shell shortcut

• Update packages using pacman:

    pacman -Syuu  
  

  Copy

• Exit the MSYS shell using Alt+F4

• Edit the properties for the MSYS2 Shell shortcut changing "msys2_shell.bat" to "msys2_shell.cmd -mingw64" for 64-bit builds or "msys2_shell.cmd -mingw32" for 32-bit builds

• Restart MSYS shell via modified shortcut and update packages again using pacman:

    pacman -Syuu  
  

  Copy

• Install dependencies:

  To build for 64-bit Windows:

    pacman -S mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-openssl mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium
  

  Copy

  To build for 32-bit Windows:

    pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-zeromq mingw-w64-i686-libsodium
  

  Copy

• Open the MingW shell via MinGW-w64-Win64 Shell shortcut on 64-bit Windows or MinGW-w64-Win64 Shell shortcut on 32-bit Windows. Note that if you are running 64-bit Windows, you will have both 64-bit and 32-bit MinGW shells.

Building

• If you are on a 64-bit system, run:

    make release-static-win64
  

  Copy

• If you are on a 32-bit system, run:

    make release-static-win32
  

  Copy

• The resulting executables can be found in build/release/bin

⁠On FreeBSD:

The project can be built from scratch by following instructions for Linux above. If you are running electronero in a jail you need to add the flag: allow.sysvipc=1 to your jail configuration, otherwise lmdb will throw the error message: Failed to open lmdb environment: Function not implemented.

We expect to add Electronero into the ports tree in the near future, which will aid in managing installations using ports or packages.

⁠On OpenBSD:

⁠OpenBSD < 6.2

This has been tested on OpenBSD 5.8.

You will need to add a few packages to your system. pkg_add db cmake gcc gcc-libs g++ miniupnpc gtest.

The doxygen and graphviz packages are optional and require the xbase set.

The Boost package has a bug that will prevent librpc.a from building correctly. In order to fix this, you will have to Build boost yourself from scratch. Follow the directions here (under "Building Boost"): https://github.com/bitcoin/bitcoin/blob/master/doc/build-openbsd.md⁠

You will have to add the serialization, date_time, and regex modules to Boost when building as they are needed by Electronero.

To build: env CC=egcc CXX=eg++ CPP=ecpp DEVELOPER_LOCAL_TOOLS=1 BOOST_ROOT=/path/to/the/boost/you/built make release-static-64

⁠OpenBSD >= 6.2

You will need to add a few packages to your system. pkg_add cmake miniupnpc zeromq libiconv.

The doxygen and graphviz packages are optional and require the xbase set.

Build the Boost library using clang. This guide is derived from: https://github.com/bitcoin/bitcoin/blob/master/doc/build-openbsd.md⁠

We assume you are compiling with a non-root user and you have doas enabled.

Note: do not use the boost package provided by OpenBSD, as we are installing boost to /usr/local.
