## Introduction
|
|
|
|
Monero is a private, secure, untraceable currency. You are your bank, you control your funds, and nobody can trace your transfers unless you decide 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 24 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, committed to the "development" branch, and then subsequently tested by contributors who focus on thorough 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. If you have a fix or code change, feel free to submit is as a pull request directly to the "development" 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.
|

|
### Build instructions
|
|
|
|
Monero uses the CMake build system and a top-level [Makefile](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 bitmonero
|
|
make
|
|
|
|
*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.
|
|
|
|
* The resulting executables can be found in `build/release/bin`.
|
|
|
|
* **Optional**: build and run the test suite to verify the binaries:
|
|
|
|
make release-test
|
|
|
|
*NOTE*: `coretests` test may take a few hours to complete.
|
|
|
|
* **Optional**: to build binaries suitable for debugging:
|
|
|
|
make debug
|
|
|
|
* **Optional**: to build statically-linked binaries:
|
|
|
|
make release-static
|
|
|
|
#### On Windows:
|
|
|
|
Binaries for Windows are built on Windows using the MinGW toolchain within
|
|
[MSYS2 environment](http://msys2.github.io). 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](http://msys2.github.io), either the 64-bit or the 32-bit package, depending on your system.
|
|
* Open the MSYS shell via the `MSYS2 Shell` shortcut
|
|
* Update the packages in your MSYS2 install:
|
|
|
|
pacman -Sy
|
|
pacman -Su --ignoregroup base
|
|
pacman -Su
|
|
|
|
For those of you already familiar with pacman, you can run the normal `pacman -Syu` to update, but you may get errors and need to restart MSYS2 if pacman's dependencies are updated.
|
|
|
|
* 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
|
|
|
|
To build for 32-bit Windows:
|
|
|
|
pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost
|
|
|
|
* 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
|
|
|
|
* If you are on a 32-bit system, run:
|
|
|
|
make release-static-win32
|
|
|
|
* 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.
|
|
|
|
We expect to add Monero into the ports tree in the near future, which will aid in managing installations using ports or packages.
|
|
|
|
### On OpenBSD:
|
|
|
|
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 Monero.
|
|
|
|
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`
|
|
|
|
### Building Portable Statically Linked Binaries
|
|
|
|
By default, in either dynamically or statically linked builds, binaries target the specific host processor on which the build happens and are not portable to other processors. Portable binaries can be built using the following targets:
|
|
|
|
* ```make release-static-64``` builds binaries on Linux on x86_64 portable across POSIX systems on x86_64 processors
|
|
* ```make release-static-32``` builds binaries on Linux on x86_64 or i686 portable across POSIX systems on i686 processors
|
|
* ```make release-static-arm7``` builds binaries on Linux on armv7 portable across POSIX systesm on armv7 processors
|
|
* ```make release-static-arm6``` builds binaries on Linux on armv7 or armv6 portable across POSIX systems on armv6 processors, such as the Raspberry Pi
|
|
* ```make release-static-win64``` builds binaries on 64-bit Windows portable across 64-bit Windows systems
|
|
* ```make release-static-win32``` builds binaries on 64-bit or 32-bit Windows portable across 32-bit Windows systems
|
|
|
|
### Building Documentation
|
|
|
|
Monero developer documentation uses Doxygen, and is currently a work-in-progress.
|
|
|
|
Dependencies: Doxygen `>=1.8.0`, Graphviz `>=2.28` (optional).
|
|
|
|
* To build the HTML documentation without diagrams, change
|
|
to the root of the source code directory, and run
|
|
|
|
doxygen Doxyfile
|
|
|
|
* To build the HTML documentation with diagrams (Graphviz required):
|
|
|
|
HAVE_DOT=YES doxygen Doxyfile
|
|
|
|
* The output will be built in doc/html/
|
|
|
|
## Running bitmonerod
|
|
|
|
The build places the binary in `bin/` sub-directory within the build directory
|
|
from which cmake was invoked (repository root by default). To run in
|
|
foreground:
|
|
|
|
./bin/bitmonerod
|
|
|
|
To run in background:
|
|
|
|
./bin/bitmonerod --log-file bitmonerod.log --detach
|
|
|
|
To list all available options, run `./bin/bitmonerod --help`. Options can be
|
|
specified either on the command line or in a configuration file passed by the
|
|
`--config-file` argument. To specify an option in the configuration file, add
|
|
a line with the syntax `argumentname=value`, where `argumentname` is the name
|
|
of the argument without the leading dashes, for example `log-level=1`.
|
|
|
|
## Internationalization
|
|
|
|
See README.i18n
|
|
|
|
## Using Tor
|
|
|
|
While Monero isn't made to integrate with Tor, it can be used wrapped with torsocks, if you add --p2p-bind-ip 127.0.0.1 to the bitmonerod command line. You also want to set DNS requests to go over TCP, so they'll be routed through Tor, by setting DNS_PUBLIC=tcp. You may also disable IGD (UPnP port forwarding negotiation), which is pointless with Tor. To allow local connections from the wallet, add TORSOCKS_ALLOW_INBOUND=1. Example:
|
|
|
|
`DNS_PUBLIC=tcp TORSOCKS_ALLOW_INBOUND=1 torsocks bitmonerod --p2p-bind-ip 127.0.0.1 --no-igd`
|
|
|
|
TAILS ships with a very restrictive set of firewall rules. Therefore, you need to add a rule to allow this connection too, in addition to telling torsocks to allow inbound connections. Full example:
|
|
|
|
`sudo iptables -I OUTPUT 2 -p tcp -d 127.0.0.1 -m tcp --dport 18081 -j ACCEPT`
|
|
|
|
`DNS_PUBLIC=tcp TORSOCKS_ALLOW_INBOUND=1 torsocks ./bitmonerod --p2p-bind-ip 127.0.0.1 --no-igd --rpc-bind-ip 127.0.0.1 --data-dir /home/amnesia/Persistent/your/directory/to/the/blockchain`
|
|
|
|
`./simplewallet`
|
|
|
|
## Using readline
|
|
|
|
While bitmonerod and simplewallet do not use readline directly, most of the functionality can be obtained by running them via rlwrap. This allows command recall, edit capabilities, etc. It does not give autocompletion without an extra completion file, however. To use rlwrap, simply prepend `rlwrap` to the command line, eg:
|
|
|
|
`rlwrap bin/simplewallet --wallet-file /path/to/wallet`
|
