-## Research
-
-The [Monero Research Lab](https://src.getmonero.org/resources/research-lab/) is an open forum where the community coordinates research into Monero cryptography, protocols, fungibility, analysis, and more. We welcome collaboration and contributions from outside researchers! Because not all Lab work and publications are distributed as traditional preprints or articles, they may be easy to miss if you are conducting literature reviews for your own Monero research. You are encouraged to get in touch with our researchers if you have questions, wish to collaborate, or would like guidance to help avoid unnecessarily duplicating earlier or known work.

 ## 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.
-
-## Supporting the project
-
-Monero is a 100% community-sponsored endeavor. If you want to join our efforts, the easiest thing you can do is support the project financially. Both Monero and Bitcoin donations can be made to **donate.getmonero.org** if using a client that supports the [OpenAlias](https://openalias.org) standard. Alternatively you can send XMR to the Monero donation address via the `donate` command (type `help` in the command-line wallet for details).
-
-The Monero donation address is: `44AFFq5kSiGBoZ4NMDwYtN18obc8AemS33DBLWs3H7otXft3XjrpDtQGv7SqSsaBYBb98uNbr2VBBEt7f2wfn3RVGQBEP3A` (viewkey: `f359631075708155cc3d92a32b75a7d02a5dcf27756707b47a2b31b21c389501`)

+Wownero is a privacy-centric memecoin that was fairly launched on April 1, 2018 with no pre-mine, stealth-mine or ICO. Wownero has a maximum supply of around 184 million WOW with a slow and steady emission over 50 years. It is a fork of Monero, but with its own genesis block, so there is no degradation of privacy due to ring signatures using different participants for the same tx outputs on opposing forks.
 
 ## 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.

This means that users of Wownero (end users and service providers) should run current versions and upgrade their software on a regular schedule. 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 Wownero software version. Below is the historical schedule and the projected schedule for the next upgrade.
 Dates are provided in the format YYYY-MM-DD.

-## Release staging schedule and protocol
+## Release staging and Contributing
 
-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. 
+**Anyone is welcome to contribute to Wownero's codebase!** 
 
-## Compiling Monero from source
+If you have a fix or code change, feel free to submit it as a pull request. Ahead of a scheduled software upgrade, a development branch will be created with the new release version tag. Pull requests that address bugs should be made to Master. Pull requests that require review and testing (generally, optimizations and new features) should be made to the development branch. All pull requests will be considered safe until the US dollar valuation of 1 Wownero equals $1000. After this valuation has been reached, more research will be needed to introduce experimental cryptography and/or code into the codebase.  
 
-### 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`).

-[1] 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/ ```
-[2] libnorm-dev is needed if your zmq library was built with libnorm, and not needed otherwise
-
-Debian / Ubuntu one liner for all dependencies  
-``` sudo apt update && sudo apt install build-essential cmake pkg-config libboost-all-dev libssl-dev libzmq3-dev libunbound-dev libsodium-dev libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev doxygen graphviz libpgm-dev```
-
-### Cloning the repository
-
-Clone recursively to pull-in needed submodule(s):
-
-`$ git clone --recursive https://github.com/monero-project/monero`
-
-If you already have a repo cloned, initialize and update:
-
-`$ cd monero && git submodule init && git submodule update`
-
-### 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, change to the most recent release branch, and build:
-
-        cd monero
-        git checkout v0.13.0.4
-        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.
-
-    *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.
-    
-    *Note*: The instructions above will compile the most stable release of the
-    Monero software. If you would like to use and test the most recent software,
-    use ```git checkout master```. The master branch may contain updates that are
-    both unstable and incompatible with release software, though testing is always 
-    encouraged. 
-
-* The resulting executables can be found in `build/release/bin`
-
-* Add `PATH="$PATH:$HOME/monero/build/release/bin"` to `.profile`
-
-* Run Monero with `monerod --detach`
-
-* **Optional**: build and run the test suite to verify the binaries:
-
-        make release-test
-
-    *NOTE*: `core_tests` 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
-
-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
-
-#### 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](#note-for-raspbian-jessie-users). 
-
-* `apt-get update && apt-get upgrade` to install all of the latest software
-
-* Install the dependencies for Monero 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=2048
-	sudo /etc/init.d/dphys-swapfile start  
-```
-* If using an external hard disk without an external power supply, ensure it gets enough power to avoid hardware issues when syncing, by adding the line "max_usb_current=1" to /boot/config.txt
-
-* Clone monero and checkout most recent release version:
-```
-        git clone https://github.com/monero-project/monero.git
-	cd monero
-	git checkout tags/v0.13.0.4
-```
-* Build:
-```
-        make release
-```
-* Wait 4-6 hours
-
-* The resulting executables can be found in `build/release/bin`
-
-* Add `PATH="$PATH:$HOME/monero/build/release/bin"` to `.profile`
-
-* Run Monero 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
-
-#### *Note for Raspbian Jessie users:*
-
-If you are using the older Raspbian Jessie image, compiling Monero is a bit more complicated. The version of Boost available in the Debian Jessie repositories is too old to use with Monero, 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=2048  
-	sudo /etc/init.d/dphys-swapfile start  
-```
-
-* Then, install the dependencies for Monero 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  
-```
-* Wait ~8 hours
-```
-	sudo ./bjam cxxflags=-fPIC cflags=-fPIC -a install
-```
-* Wait ~4 hours
-
-* From here, follow the [general Raspberry Pi instructions](#on-the-raspberry-pi) from the "Clone monero and checkout most recent release version" step.
-
-#### On Windows:
-
-Binaries for Windows are built on Windows using the MinGW toolchain within
-[MSYS2 environment](https://www.msys2.org). 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](https://www.msys2.org), 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 mingw-w64-x86_64-openssl mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium mingw-w64-x86_64-hidapi
-
-    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 mingw-w64-i686-hidapi
-
-* 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.
-
-**Cloning**
-
-* To git clone, run:
-
-        git clone --recursive https://github.com/monero-project/monero.git
-
-**Building**
-
-* Change to the cloned directory, run:
-	
-        cd monero
-
-* If you would like a specific [version/tag](https://github.com/monero-project/monero/tags), do a git checkout for that version. eg. 'v0.13.0.0'. If you dont care about the version and just want binaries from master, skip this step:
-	
-        git checkout v0.13.0.4
-
-* 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`
-
-* **Optional**: to build Windows binaries suitable for debugging on a 64-bit system, run:
-
-        make debug-static-win64
-	
-* **Optional**: to build Windows binaries suitable for debugging on a 32-bit system, run:
-
-        make debug-static-win32
-
-* The resulting executables can be found in `build/debug/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 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++ 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`
-
-#### OpenBSD >= 6.2
-
-You will need to add a few packages to your system. `pkg_add cmake 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`.

-### On Solaris:
-
-The default Solaris linker can't be used, you have to install GNU ld, then run cmake manually with the path to your copy of GNU ld:
-
-        mkdir -p build/release
-        cd build/release
-        cmake -DCMAKE_LINKER=/path/to/ld -D CMAKE_BUILD_TYPE=Release ../..
-        cd ../..
-
-Then you can run make as usual.

-        docker build -f utils/build_scripts/android32.Dockerfile -t monero-android .
-        # Build image (for ARM 64-bit)
-        docker build -f utils/build_scripts/android64.Dockerfile -t monero-android .
-        # Create container
-        docker create -it --name monero-android monero-android bash
-        # Get binaries
-        docker cp monero-android:/src/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-linux-x86_64``` builds binaries on Linux on x86_64 portable across POSIX systems on x86_64 processors
-* ```make release-static-linux-i686``` builds binaries on Linux on x86_64 or i686 portable across POSIX systems on i686 processors
-* ```make release-static-linux-armv8``` builds binaries on Linux portable across POSIX systems on armv8 processors
-* ```make release-static-linux-armv7``` builds binaries on Linux portable across POSIX systems on armv7 processors
-* ```make release-static-linux-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
-
-### Cross Compiling
-
-You can also cross-compile static binaries on Linux for Windows and macOS with the `depends` system.
-
-* ```make depends target=x86_64-linux-gnu``` for 64-bit linux binaries.
-* ```make depends target=x86_64-w64-mingw32``` for 64-bit windows binaries. Requires: python3 g++-mingw-w64-x86-64 wine1.6 bc
-* ```make depends target=x86_64-apple-darwin11``` for macOS binaries. Requires: cmake imagemagick libcap-dev librsvg2-bin libz-dev libbz2-dev libtiff-tools python-dev
-* ```make depends target=i686-linux-gnu``` for 32-bit linux binaries. Requires: g++-multilib bc
-* ```make depends target=i686-w64-mingw32``` for 32-bit windows binaries. Requires: python3 g++-mingw-w64-i686
-* ```make depends target=arm-linux-gnueabihf``` for armv7 binaries. Requires: g++-arm-linux-gnueabihf
-* ```make depends target=aarch64-linux-gnu``` for armv8 binaries. Requires: g++-aarch64-linux-gnu
-
-The required packages are the names for each toolchain on apt. Depending on your distro, they may have different names.
-
-Using `depends` might also be easier to compile Monero on Windows than using MSYS. Activate Windows Subsystem for Linux (WSL) with a distro (for example Ubuntu), install the apt build-essentials and follow the `depends` steps as depicted above.

-## Using Tor
+## Wownero Graphical Wallets
 
-While Monero isn't made to integrate with Tor, it can be used wrapped with torsocks, by
-setting the following configuration parameters and environment variables:
+* [Wownero-Light-Wallet](https://github.com/wownero/Wownero-Light-Wallet)
 
-* `--p2p-bind-ip 127.0.0.1` on the command line or `p2p-bind-ip=127.0.0.1` in
-  monerod.conf to disable listening for connections on external interfaces.
-* `--no-igd` on the command line or `no-igd=1` in monerod.conf to disable IGD
-  (UPnP port forwarding negotiation), which is pointless with Tor.
-* `DNS_PUBLIC=tcp` or `DNS_PUBLIC=tcp://x.x.x.x` where x.x.x.x is the IP of the
-  desired DNS server, for DNS requests to go over TCP, so that they are routed
-  through Tor. When IP is not specified, monerod uses the default list of
-  servers defined in [src/common/dns_utils.cpp](src/common/dns_utils.cpp).
-* `TORSOCKS_ALLOW_INBOUND=1` to tell torsocks to allow monerod to bind to interfaces
-   to accept connections from the wallet. On some Linux systems, torsocks
-   allows binding to localhost by default, so setting this variable is only
-   necessary to allow binding to local LAN/VPN interfaces to allow wallets to
-   connect from remote hosts. On other systems, it may be needed for local wallets
-   as well.
-* Do NOT pass `--detach` when running through torsocks with systemd, (see
-  [utils/systemd/monerod.service](utils/systemd/monerod.service) for details).
-* If you use the wallet with a Tor daemon via the loopback IP (eg, 127.0.0.1:9050),
-  then use `--untrusted-daemon` unless it is your own hidden service.
+![](https://light.wownero.com/wowlight.png)
 
-Example command line to start monerod through Tor:
 
-    DNS_PUBLIC=tcp torsocks monerod --p2p-bind-ip 127.0.0.1 --no-igd
+* [Wownerujo Android Wallet](https://github.com/wownero/wownerujo)

+![](https://fossdroid.com/images/screenshots/com.wownero.wownerujo/wownerujo-2.png)
 
-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:
+## Donating to Wownero Project

-## Debugging
+Donations may also be sent to: 
 
-This section contains general instructions for debugging failed installs or problems encountered with Monero. First ensure you are running the latest version built from the Github repo.
+XMR: `44SQVPGLufPasUcuUQSZiF5c9BFzjcP8ucDxzzFDgLf1VkCEFaidJ3u2AhSKMhPLKA3jc2iS8wQHFcaigM6fXmo6AnFRn5B`
 
-### 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
-
-Enter `echo core | sudo tee /proc/sys/kernel/core_pattern` to stop cores from being hijacked by other tools
-
-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. It may be named just `core`, or `core.xxxx` with numbers appended.
-
-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
-
-There are two tools available:
-
-* ASAN
-
-Configure Monero with the -D SANITIZE=ON cmake flag, eg:
-
-    cd build/debug && cmake -D SANITIZE=ON -D CMAKE_BUILD_TYPE=Debug ../..
-
-You can then run the monero tools normally. Performance will typically halve.
-
-* valgrind
-
-Install valgrind and run as `valgrind /path/to/monerod`. It will be very 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.
