It's better to just ignore them, the user does not really need
to know they're here. If the mask is wrong, they'll fail to be
used, and sweeping will fail as it tries to use it.
Reported by Josh Davis.
Always send TX public key when generating output destination keys: it may be an additional TX public key in case of subaddress; before we always use R.
Fix the commitment mask generation: It must be delegated to device as it implies the amount key.
Send MONERO_VERSION string in reset command to allow version compatibility check.
Some enhancement of debug log.
Half of the patch was correct, but half was introducing another bug,
where a wallet asking for a fork that the daemon does not know about
yet would decide to use those rules.
If two create_block_template are called at nearly the same time,
and a block is added at nearly the same time, this could happen:
- the blockchain top block is B0
- thread 1 enters create_block_template, takes blockchain lock
- thread 1 creates a fresh block referencing prev block B0
- thread 1 releases blockchain lock
- thread 0 adds a new block
- thread 0 enters create_block_template
- thread 0 updates block template
- thread 1 takes txpool lock and continues creating block template
- thread 1 overwrites block template with previous data
- These functions are declared twice in slow-hash.c. Remove one of the copies.
- The declarations have the wrong return type, should be void, not int.

Test plan: make release-test
The change made for v2 broke v1, and we have no way to know which
version we're serializing here. However, since we don't actually
care about space savings in this case, we continue serialiazing
both mask and amount.
The 10 minute one will never trigger for 0 blocks, as it's still
fairly likely to happen even without the actual hash rate changing
much, so we add a 20 minute window, where it will (for 0 blocks)
and a one hour window.
This will trigger if a reorg is seen. This may be used to do things
like stop automated withdrawals on large reorgs.
%s is replaced by the height at the split point
%h is replaced by the height of the new chain
%n is replaced by the number of new blocks after the reorg
This curbs runaway growth while still allowing substantial
spikes in block weight
Original specification from ArticMine:
here is the scaling proposal
Define: LongTermBlockWeight
Before fork:
LongTermBlockWeight = BlockWeight
At or after fork:
LongTermBlockWeight = min(BlockWeight, 1.4*LongTermEffectiveMedianBlockWeight)
Note: To avoid possible consensus issues over rounding the LongTermBlockWeight for a given block should be calculated to the nearest byte, and stored as a integer in the block itself. The stored LongTermBlockWeight is then used for future calculations of the LongTermEffectiveMedianBlockWeight and not recalculated each time.
Define: LongTermEffectiveMedianBlockWeight
LongTermEffectiveMedianBlockWeight = max(300000, MedianOverPrevious100000Blocks(LongTermBlockWeight))
Change Definition of EffectiveMedianBlockWeight
From (current definition)
EffectiveMedianBlockWeight = max(300000, MedianOverPrevious100Blocks(BlockWeight))
To (proposed definition)
EffectiveMedianBlockWeight = min(max(300000, MedianOverPrevious100Blocks(BlockWeight)), 50*LongTermEffectiveMedianBlockWeight)
Notes:
1) There are no other changes to the existing penalty formula, median calculation, fees etc.
2) There is the requirement to store the LongTermBlockWeight of a block unencrypted in the block itself. This is to avoid possible consensus issues over rounding and also to prevent the calculations from becoming unwieldy as we move away from the fork.
3) When the EffectiveMedianBlockWeight cap is reached it is still possible to mine blocks up to 2x the EffectiveMedianBlockWeight by paying the corresponding penalty.
0 is placeholder for whole chain, so we should compare chain
height changes rather than chain-height-or-zero. Even this isn't
totally foolproof if a blocks are popped and the same number
added again, but it is much better as it prevents the data from
slowly going out of sync.
The Docker image is failing to build, as the submodules are not being
explicitly initialized and updated.

Those take a command line of the form "A [B]", with A being the
name (and optional path, if not in the caller's CWD, but fully
qualified path is recommended, avoids possible security issues)
to a program, and optional arguments. Any occurence of the two
character string "%s" will be replaced by the hash of the block
or transaction which triggered the notification.
Tokenization is barebones. If you want things like pipes, calls
to paths with spaces, etc, then use a script (though exec time
will suffer).
block-notify is called when a new block is added onto the chain.
tx-notify is called when a new transaction happens with the
wallet as source and/or destination.
It is the notification program's responsibility to determine what
to do in those cases.
Note that this is asynchronous, so it is very possible that:
- the notification programs will be run out of order
- several events happen before the notification for the first one
A Windows port would be nice if someone wants to make one.

## Build
### IMPORTANT
These builds are of the master branch, which is used for active development and can be either unstable or incompatible with release software. Please compile release branches.
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`)
The Bitcoin donation address is: `1KTexdemPdxSBcG55heUuTjDRYqbC5ZL8H`
Core development funding and/or some supporting services are also graciously provided by sponsors:
There are also several mining pools that kindly donate a portion of their fees, [a list of them can be found on our Bitcointalk post](https://bitcointalk.org/index.php?topic=583449.0).

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.

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.
## Compiling Monero 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 | Fedora | Optional | Purpose |
| expat | 1.1 | NO | `libexpat1-dev` | `expat` | `expat-devel` | YES | XML parsing |
| GTest | 1.5 | YES | `libgtest-dev`^ | `gtest` | `gtest-devel` | YES | Test suite |
| Doxygen | any | NO | `doxygen` | `doxygen` | `doxygen` | YES | Documentation |
| Graphviz | any | NO | `graphviz` | `graphviz` | `graphviz` | YES | Documentation |
| pcsclite | ? | NO | `libpcsclite-dev` | ? | `pcsc-lite pcsc-lite-devel` | NO | Ledger |
[^] 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/ ```
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 v0.13.0.0
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=1024
sudo /etc/init.d/dphys-swapfile start
```
* Clone monero and checkout most recent release version:
* 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=1024
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):
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
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
* 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.
**Anyone is welcome to contribute to Wownero's codebase!**
**Building**
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.
* 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 v0.13.0.0
* 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"):
### Building portable statically linked binaries (Cross Compiling)
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
## Installing Monero from a package
**DISCLAIMER: These packages are not part of this repository or maintained by this project's contributors, and as such, do not go through the same review process to ensure their trustworthiness and security.**
## Installing from a package
Packages are available for
* Ubuntu and [snap supported](https://snapcraft.io/docs/core/install) systems, via a community contributed build.
* Arch Linux/Manjaro
snap install monero --beta
yay -S wownero-git
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.
* NixOS
* Arch Linux (via [AUR](https://aur.archlinux.org/)):
# or build using a specific number of cores (reduce RAM requirement)
docker build --build-arg NPROC=1 -t monero .
Packaging for your favorite distribution would be a welcome contribution!
# either run in foreground
docker run -it -v /monero/chain:/root/.bitmonero -v /monero/wallet:/wallet -p 18080:18080 monero
**DISCLAIMER: These packages are not part of this repository, and as such, do not go through the same review process to ensure their trustworthiness and security.**
Using depends might also be easier to compile monero on windows than using msys. Activate windows subsystem for linux (for example ubuntu) install the apt build-essentials and follow the depends steps as depicted above.
## Running monerod
## Running Binaries
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
./bin/wownerod
To list all available options, run `./bin/monerod --help`. Options can be
To list all available options, run `./bin/wownerod --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
@ -566,130 +109,39 @@ of the argument without the leading dashes, for example `log-level=1`.
To run in background:
./bin/monerod --log-file monerod.log --detach
./bin/wownerod --log-file wownerod.log --detach
To run as a systemd service, copy
[monerod.service](utils/systemd/monerod.service) to `/etc/systemd/system/` and
[monerod.conf](utils/conf/monerod.conf) to `/etc/`. The [example
service](utils/systemd/monerod.service) assumes that the user `monero` exists
[wownerod.service](utils/systemd/wownerod.service) to `/etc/systemd/system/` and
[wownerod.conf](utils/conf/wownerod.conf) to `/etc/`. The [example
service](utils/systemd/wownerod.service) assumes that the user `wownero` exists
and its home is the data directory specified in the [example
config](utils/conf/monerod.conf).
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](README.i18n.md).
## Using Tor
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:
* `--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.
Example command line to start monerod through Tor:
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.
### 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
config](utils/conf/wownerod.conf).
There are two tools available:
Once node is synced to network, run the CLI wallet by entering:
* ASAN
./bin/wownero-wallet-cli
Configure Monero with the -D SANITIZE=ON cmake flag, eg:
Type `help` in CLI wallet to see standard commands (for advanced options, type `help_advanced`).
cd build/debug && cmake -D SANITIZE=ON -D CMAKE_BUILD_TYPE=Debug ../..
## Wownero Graphical Wallets
You can then run the monero tools normally. Performance will typically halve.
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:
## Donating to Wownero Project
`cd ~/monero/external/db_drivers/liblmdb && make`
Developers are volunteers doing this mostly for shits and giggles. If you would like to support our shenanigans and stimulant addictions, please consider donating to [WFS proposals](https://funding.wownero.com/proposals) or the [dev slush fund](https://funding.wownero.com/donate).
The output of `mdb_stat -ea <path to blockchain dir>` will indicate inconsistencies in the blocks, block_heights and block_info table.
Donations may also be sent to:
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.
