Due to the nature of this open source software project, joining this channel and idling is the best way to stay updated on best practices and new developments in the Monero ecosystem. All you need to do is join the IRC channel and idle to stay updated with the latest in Monero development. If you do not, you risk wasting resources on developing integrations that are not compatible with the Monero network. The Monero core team and community continuously make efforts to communicate updates, developments, and documentation via other platforms – but for the best information, you need to talk to other Monero developers, and they are on IRC. #monero-dev is about Monero development, not getting help about using Monero, or help about development of other software, including yours, unless it also pertains to Monero code itself.

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 the Monero research community if you have questions, wish to collaborate, or would like guidance to help avoid unnecessarily duplicating earlier or known work. - -The Monero research community is available on IRC in [#monero-research-lab on Libera](https://web.libera.chat/#monero-research-lab), which is also accessible via Matrix. - -## Announcements - -- You can subscribe to an [announcement listserv](https://lists.getmonero.org) to get critical announcements from the Monero core team. The announcement list can be very helpful for knowing when software updates are needed. - -## Translations -The CLI wallet is available in different languages. If you want to help translate it, see our self-hosted localization platform, Weblate, on [translate.getmonero.org]( https://translate.getmonero.org/projects/monero/cli-wallet/). Every translation *must* be uploaded on the platform, pull requests directly editing the code in this repository will be closed. If you need help with Weblate, you can find a guide with screenshots [here](https://github.com/monero-ecosystem/monero-translations/blob/master/weblate.md). -  - -If you need help/support/info about translations, contact the localization workgroup.

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 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 should be encrypted with a strong passphrase to ensure they are useless if ever 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. - -**Decentralization:** The utility of Monero depends on its decentralised peer-to-peer consensus network - anyone should be able to run the monero software, validate the integrity of the blockchain, and participate in all aspects of the monero network using consumer-grade commodity hardware. Decentralization of the monero network is maintained by software development that minimizes the costs of running the monero software and inhibits the proliferation of specialized, non-commodity hardware. - -## 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. +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. ## 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). +Wownero is a 100% community-sponsored endeavor.

The platform brings together legal entities that act as a “Fiscal Host”, “Collectives” (unincorporated, community-based projects), and individuals interested in supporting projects with donations. Fiscal hosts hold donations for collectives in trust and handle all the taxes and legal stuff. + +Wownero is hosted by Open Collective Europe, a Brussels-based non-profit that hosts many other collectives, such as Manjaro, EndeavourOS, Xfce, and peertube.social. If you would like donate to the Wownero Project using this method, you can check out our [Wownero - Open Collective](https://opencollective.com/wownero) page. + +## Release staging and Contributing + +**Anyone is welcome to contribute to Wownero's codebase!** + +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. + +Things to Do, Work in Progress, and Help Wanted tasks are tracked in the [Meta](https://git.wownero.com/wownero/meta/issues) repo. + +Join `#wownero` on IRC OFTC to participate in development conversation. ## 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. +Wownero uses a fixed-schedule software upgrade (hard fork) mechanism to implement new features.

For - this to be worthwhile, the machine should have one core and about 2GB of RAM - available per thread. - - *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: - - ```bash - make release-test - ``` - - *NOTE*: `core_tests` test may take a few hours to complete. - -* **Optional**: to build binaries suitable for debugging: - - ```bash - make debug - ``` - -* **Optional**: to build statically-linked binaries: - - ```bash - 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): - - ```bash - HAVE_DOT=YES doxygen Doxyfile - ``` - -* **Optional**: use ccache not to rebuild translation units, that haven't really changed. Monero's CMakeLists.txt file automatically handles it - - ```bash - sudo apt install ccache - ``` - -#### 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: - - ```bash - 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 the most recent release version: - - ```bash - git clone https://github.com/monero-project/monero.git - cd monero - git checkout v0.18.3.2 - ``` - -* Build: - - ```bash - USE_SINGLE_BUILDDIR=1 make release - ``` - -* Wait 4-6 hours - -* The resulting executables can be found in `build/release/bin` - -* Add `export PATH="$PATH:$HOME/monero/build/release/bin"` to `$HOME/.profile` - -* Run `source $HOME/.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 - - ```bash - 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 for `libunwind` and `libboost-all-dev` - -* Install the latest version of boost (this may first require invoking `apt-get remove --purge libboost*-dev` to remove a previous version if you're not using a clean install): - - ```bash - cd - wget https://sourceforge.net/projects/boost/files/boost/1.72.0/boost_1_72_0.tar.bz2 - tar xvfo boost_1_72_0.tar.bz2 - cd boost_1_72_0 - ./bootstrap.sh - sudo ./b2 - ``` - -* Wait ~8 hours - - ```bash - 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: - - ```bash - pacman -Syu - ``` - -* 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: - - ```bash - pacman -Syu - ``` - - -* Install dependencies: - - To build for 64-bit Windows: - - ```bash - 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 mingw-w64-x86_64-unbound - ``` - - To build for 32-bit Windows: - - ```bash - 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 mingw-w64-i686-unbound - ``` - -* 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: - - ```bash - git clone --recursive https://github.com/monero-project/monero.git - ``` - -**Building** - -* Change to the cloned directory, run: - - ```bash - 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. 'v0.18.3.2'. If you don't care about the version and just want binaries from master, skip this step: - - ```bash - git checkout v0.18.3.2 - ``` - -* If you are on a 64-bit system, run: - - ```bash - make release-static-win64 - ``` - -* If you are on a 32-bit system, run: - - ```bash - 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: - - ```bash - make debug-static-win64 - ``` - -* **Optional**: to build Windows binaries suitable for debugging on a 32-bit system, run: - - ```bash - 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(but use `gmake` instead of `make`). -If you are running Monero in a jail, you need to add `sysvsem="new"` to your jail configuration, otherwise lmdb will throw the error message: `Failed to open lmdb environment: Function not implemented`. - -Monero is also available as a port or package as `monero-cli`. - -### On OpenBSD: - -You will need to add a few packages to your system. `pkg_add cmake gmake zeromq libiconv boost`. - -The `doxygen` and `graphviz` packages are optional and require the xbase set. -Running the test suite also requires `py-requests` package. - -Build monero: `env DEVELOPER_LOCAL_TOOLS=1 BOOST_ROOT=/usr/local gmake release-static` - -Note: you may encounter the following error when compiling the latest version of Monero as a normal user: - -``` -LLVM ERROR: out of memory -c++: error: unable to execute command: Abort trap (core dumped) -``` - -Then you need to increase the data ulimit size to 2GB and try again: `ulimit -d 2000000` - -### On NetBSD: - -Check that the dependencies are present: `pkg_info -c libexecinfo boost-headers boost-libs protobuf readline libusb1 zeromq git-base pkgconf gmake cmake | more`, and install any that are reported missing, using `pkg_add` or from your pkgsrc tree. Readline is optional but worth having. - -Third-party dependencies are usually under `/usr/pkg/`, but if you have a custom setup, adjust the "/usr/pkg" (below) accordingly. - -Clone the monero repository recursively and checkout the most recent release as described above. Then build monero: `gmake BOOST_ROOT=/usr/pkg LDFLAGS="-Wl,-R/usr/pkg/lib" release`. The resulting executables can be found in `build/NetBSD/[Release version]/Release/bin/`. - -### 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: - -```bash -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. - -### 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` -* ```make depends target=riscv64-linux-gnu``` for RISC V 64 bit binaries. - * Requires: `g++-riscv64-linux-gnu` -* ```make depends target=x86_64-unknown-freebsd``` for freebsd binaries. - * Requires: `clang-8` -* ```make depends target=arm-linux-android``` for 32bit android binaries -* ```make depends target=aarch64-linux-android``` for 64bit android binaries - - -The required packages are the names for each toolchain on apt. Depending on your distro, they may have different names. The `depends` system has been tested on Ubuntu 18.04 and 20.04. - -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. - -The produced binaries still link libc dynamically. If the binary is compiled on a current distribution, it might not run on an older distribution with an older installation of libc. Passing `-DBACKCOMPAT=ON` to cmake will make sure that the binary will run on systems having at least libc version 2.17. - -## 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 -* Debian Buster +* Arch Linux/Manjaro - See the [instructions in the whonix/monero-gui repository](https://gitlab.com/whonix/monero-gui#how-to-install-monero-using-apt-get) + yay -S wownero-git -* Debian Bullseye and Sid +* Gentoo - Russian hacking tool - ```bash - sudo apt install monero - ``` -More info and versions in the [Debian package tracker](https://tracker.debian.org/pkg/monero). + emerge --noreplace eselect-repository + eselect repository enable monero + emaint sync -r monero + echo '*/*::monero ~amd64' >> /etc/portage/package.accept_keywords + emerge net-p2p/wownero -* Arch Linux [(via Community packages)](https://www.archlinux.org/packages/community/x86_64/monero/): +* NixOS - ```bash - sudo pacman -S monero - ``` - -* Void Linux: - - ```bash - xbps-install -S monero - ``` - -* GuixSD - - ```bash - guix package -i monero - ``` - -* Gentoo [Monero overlay](https://github.com/gentoo-monero/gentoo-monero) - - ```bash - emerge --noreplace eselect-repository - eselect repository enable monero - emaint sync -r monero - echo '*/*::monero ~amd64' >> /etc/portage/package.accept_keywords - emerge net-p2p/monero - ``` - -* macOS [(homebrew)](https://brew.sh/) - ```bash - brew install monero - ``` - -* Docker - - ```bash - # Build using all available cores - docker build -t monero . - - # or build using a specific number of cores (reduce RAM requirement) - docker build --build-arg NPROC=1 -t monero . - - # either run in foreground - docker run -it -v /monero/chain:/home/monero/.bitmonero -v /monero/wallet:/wallet -p 18080:18080 monero - - # or in background - docker run -it -d -v /monero/chain:/home/monero/.bitmonero -v /monero/wallet:/wallet -p 18080:18080 monero - ``` - -* The build needs 3 GB space. -* Wait one hour or more + nix-shell -p wownero Packaging for your favorite distribution would be a welcome contribution! -## Running monerod +**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.** + + +## Building from Source + +* Docker + + git clone https://git.wownero.com/wownero/wownero && cd wownero + docker build -t git-wow:master -m 4g . + docker run -it -p 34567:34567 -p 34568:34568 -w /home/wownero/build/release/bin git-wow:master bash + +* Arch Linux/Manjaro + + sudo pacman -Syu && sudo pacman -S base-devel cmake boost openssl zeromq libpgm unbound libsodium git libusb systemd + git clone https://git.wownero.com/wownero/wownero && cd wownero + make -j2 + +* Debian/Ubuntu + + 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 libpgm-dev libhidapi-dev libusb-1.0-0-dev libprotobuf-dev protobuf-compiler libudev-dev git -y + git clone https://git.wownero.com/wownero/wownero && cd wownero + make -j2 + + +## Running Binaries The build places the binary in `bin/` sub-directory within the build directory from which cmake was invoked (repository root by default).

One can store a pruned blockchain, which is about 45 GB. -A pruned blockchain can only serve part of the historical chain data to other peers, but is otherwise identical in -functionality to the full blockchain. -To use a pruned blockchain, it is best to start the initial sync with `--prune-blockchain`. However, it is also possible -to prune an existing blockchain using the `monero-blockchain-prune` tool or using the `--prune-blockchain` `monerod` option -with an existing chain. If an existing chain exists, pruning will temporarily require disk space to store both the full -and pruned blockchains. - -For more detailed information see the ['Pruning' entry in the Moneropedia](https://www.getmonero.org/resources/moneropedia/pruning.html) - -## Debugging - -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: - -```bash -gdb /path/to/monerod `pidof monerod` +./wownero-wallet-cli --proxy 127.0.0.1:9050 --daemon-address iy6ry6uudpzvbd72zsipepukp6nsazjdu72n52vg3isfnxqn342flzad.onion:34568 ``` - -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: - -```bash -gdb /path/to/monerod /path/to/dumpfile` -``` - -Print the stack trace with `bt` - - * If a program crashed and cores are managed by systemd, the following can also get a stack trace for that crash: - -```bash -coredumpctl -1 gdb -``` - -#### 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: - -```bash -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: - -```bash -cd ~/monero/external/db_drivers/liblmdb && make -``` - -The output of `mdb_stat -ea ` will indicate inconsistencies in the blocks, block_heights and block_info table. - -The output of `mdb_dump -s blocks ` and `mdb_dump -s block_info ` 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. - -# Known Issues - -## Protocols - -### Socket-based - -Because of the nature of the socket-based protocols that drive monero, certain protocol weaknesses are somewhat unavoidable at this time. While these weaknesses can theoretically be fully mitigated, the effort required (the means) may not justify the ends. As such, please consider taking the following precautions if you are a monero node operator: - -- Run `monerod` on a "secured" machine. If operational security is not your forte, at a very minimum, have a dedicated a computer running `monerod` and **do not** browse the web, use email clients, or use any other potentially harmful apps on your `monerod` machine. **Do not click links or load URL/MUA content on the same machine**. Doing so may potentially exploit weaknesses in commands which accept "localhost" and "127.0.0.1". -- If you plan on hosting a public "remote" node, start `monerod` with `--restricted-rpc`. This is a must. - -### Blockchain-based - -Certain blockchain "features" can be considered "bugs" if misused correctly. Consequently, please consider the following: - -- When receiving monero, be aware that it may be locked for an arbitrary time if the sender elected to, preventing you from spending that monero until the lock time expires. You may want to hold off acting upon such a transaction until the unlock time lapses. To get a sense of that time, you can consider the remaining blocktime until unlock as seen in the `show_transfers` command.
