Monero 0

Copyright (c) 2018, Monero 0 Copyright (c) 2014-2017, The Monero Project Portions Copyright (c) 2012-2013, The Cryptonote developers

Introduction

We are an organization that have decided to break off from the Monero Project to start Monero 0. We’ve decided that the Monero Project’s strategy to continuously hard fork is no longer a stable or a sane strategy. We believe that Satoshi’s Proof of Work is the only mechanism for decentralized consensus. The so-called "network upgrades" that are centrally mandated by the Monero Project are a trojan horse designed to compromise the effectiveness of Proof of Work in the Monero network. Monero 0 is not a fork, it is the original Monero.

Monero 0 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 0 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 0 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.

Technical Details

Monero 0 is Monero v0.11.1.0, users already using Monero v0.11.1.0 or v0.11.0.0 do not need to do anything (You may need to run monerod with argument “--add-peer IP_ADDRESS” where IP_ADDRESS is one of our nodes listed below in order to find Monero 0 peers).

159.65.227.38 167.99.96.174

New users should download Monero 0 from our github at https://github.com/monero0/monero0 , Monero 0 can be compiled off of master and binaries will be up shortly.

FAQ

Is Monero 0 a hard fork from Monero?

No. Monero hard forked from itself when updating to version 12 from 11. We are fully compatible with version 11 of the Monero Network.

Why are you against hard forking?

We believe the decision to hard fork was made by a small group of developers in a unilateral manner. The hard fork compromises the security provided by Proof of Work.

Is Monero 0 premined?

No. Premine would be impossible.

Is this an ICO?

No.

How do I get Monero 0

If you have Monero, you will already have the equivalent amount of Monero 0.

Do you have replay protection?

No. It is on the responsibility of the cryptocurrency that is hard forking to implement replay protection. To avoid replay attacks, users should simultaneously transfer their balances to new seperate wallets on Monero and Monero 0. For more information regarding replay attack and replay protection, please consult this resources here: https://bitcointechtalk.com/how-to-protect-against-replay-attacks-7a00bd2fe52f

How is this project related to Monero V?

We are not associated with Monero V. They plan to hard fork from Monero (not Monero 0) after the hard fork to version 12.

Compiling Monero 0 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).

Dep Min. Version Vendored Debian/Ubuntu Pkg Arch Pkg Optional Purpose
GCC 4.7.3 NO build-essential base-devel NO
CMake 3.0.0 NO cmake cmake NO
pkg-config any NO pkg-config base-devel NO
Boost 1.58 NO libboost-all-dev boost NO C++ libraries
OpenSSL basically any NO libssl-dev openssl NO sha256 sum
libunbound 1.4.16 YES libunbound-dev unbound NO DNS resolver
libminiupnpc 2.0 YES libminiupnpc-dev miniupnpc YES NAT punching
libunwind any NO libunwind8-dev libunwind YES Stack traces
liblzma any NO liblzma-dev xz YES For libunwind
ldns 1.6.17 NO libldns-dev ldns YES SSL toolkit

GTest 1.5 YES libgtest-dev gtest YES Test suite
Doxygen any NO doxygen doxygen YES Documentation
Graphviz any NO graphviz graphviz YES Documentation

[^] 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/

Build instructions

Monero 0 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 monero0
      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

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

  • Run Monero 0 with monerod --detach

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

      HAVE_DOT=YES doxygen Doxyfile
    

On the Raspberry Pi 2

Tested on a Raspberry Pi 2 with a clean install of minimal Debian Jessie from https://www.raspberrypi.org/downloads/raspbian/

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

  • Install the dependencies for Monero 0 except libunwind and libboost-all-dev

  • 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  
  • 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  
  • Wait ~8 hours
	sudo ./bjam install
  • Wait ~4 hours

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

        cd monero0
        make release
  • Wait ~4 hours

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

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

  • Run Monero 0 with monerod --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

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  
    
  • 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  
    
  • 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. If you are running monero 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 Monero 0 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 0.

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

On Linux for Android (using docker):

    # Build image (select android64.Dockerfile for aarch64)
    cd utils/build_scripts/ && docker build -f android32.Dockerfile -t monero-android .
    # Create container
    docker create -it --name monero-android monero-android bash
    # Get binaries
    docker cp monero-android:/opt/android/monero/build/release/bin .

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-armv8 builds binaries on Linux portable across POSIX systems on armv8 processors
  • make release-static-armv7 builds binaries on Linux portable across POSIX systems on armv7 processors
  • make release-static-armv6 builds binaries on Linux portable across POSIX systems on armv6 processors
  • 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

Running monerod

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/monerod

To list all available options, run ./bin/monerod --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.

To run in background:

./bin/monerod --log-file monerod.log --detach

To run as a systemd service, copy monerod.service to /etc/systemd/system/ and monerod.conf to /etc/. The example service assumes that the user monero exists and its home is the data directory specified in the example config.

If you're on Mac, you may need to add the --max-concurrency 1 option to monero-wallet-cli, and possibly monerod, if you get crashes refreshing.

Internationalization

See README.i18n.md.

Using Tor

While Monero 0 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 monerod 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, you might have to add TORSOCKS_ALLOW_INBOUND=1, some OSes need it and some don't. Example:

DNS_PUBLIC=tcp torsocks monerod --p2p-bind-ip 127.0.0.1 --no-igd

or:

DNS_PUBLIC=tcp TORSOCKS_ALLOW_INBOUND=1 torsocks monerod --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 ./monerod --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

./monero-wallet-cli

Using readline

While monerod and monero-wallet-cli 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/monero-wallet-cli --wallet-file /path/to/wallet

Note: rlwrap will save things like your seed and private keys, if you supply them on prompt. You may want to not use rlwrap when you use simplewallet to restore from seed, etc.

Debugging

This section contains general instructions for debugging failed installs or problems encountered with Monero 0. First ensure you are running the latest version built from the github repo.

Obtaining Stack Traces and Core Dumps on Unix Systems

We generally use the tool gdb (GNU debugger) to provide stack trace functionality, and ulimit to provide core dumps in builds which crash or segfault.

  • To use gdb in order to obtain a stack trace for a build that has stalled:

Run the build.

Once it stalls, enter the following command:

gdb /path/to/monerod `pidof monerod` 

Type thread apply all bt within gdb in order to obtain the stack trace

  • If however the core dumps or segfaults:

Enter ulimit -c unlimited on the command line to enable unlimited filesizes for core dumps

Run the build.

When it terminates with an output along the lines of "Segmentation fault (core dumped)", there should be a core dump file in the same directory as monerod.

You can now analyse this core dump with gdb as follows:

gdb /path/to/monerod /path/to/dumpfile

Print the stack trace with bt

  • To run monero within gdb:

Type gdb /path/to/monerod

Pass command-line options with --args followed by the relevant arguments

Type run to run monerod

Analysing Memory Corruption

We use the tool valgrind for this.

Run with valgrind /path/to/monerod. It will be slow.

LMDB

Instructions for debugging suspected blockchain corruption as per @HYC

There is an mdb_stat command in the LMDB source that can print statistics about the database but it's not routinely built. This can be built with the following command:

cd ~/monero/external/db_drivers/liblmdb && make

The output of mdb_stat -ea <path to blockchain dir> will indicate inconsistencies in the blocks, block_heights and block_info table.

The output of mdb_dump -s blocks <path to blockchain dir> and mdb_dump -s block_info <path to blockchain dir> is useful for indicating whether blocks and block_info contain the same keys.

These records are dumped as hex data, where the first line is the key and the second line is the data.
