In this example restbed is used to demonstrate how to provide Monero related JSON REST service. For this purpose, a service called Open Monero was developed.
Open Monero is an open source implementation of backend of https://mymonero.com/. The frontend, which includes HTML, CSS, JavaScript, was adapted from (and originally developed by) https://mymonero.com/.
Open Monero's backend is open sourced, free to use, host and modify. Additionally, some features were added/changed as compared to MyMonero. They include:
- google analytics, cloudflare, images and flash were removed.
- transaction fees were set to zero (MyMonero also has now them zero due to problem with its RingCT).
- the wallets generated use 25 word mnemonics, fully compatible with official monero wallets (13 word mnemonics generated by MyMonero work as usual though).
- import wallet fee was reduced.
- added support of testnet network and mainnet network without relying transactions
- improved handling of mempool, coinbase, locked and unlocked transactions.
- added dynamic miner fees.
- minimum mixin set to 4 for the next hard fork.
- view only mode added.
- ability to offline show your address and private view and spend keys, based on the mnemonic seed, in case of server or connections problem.
- private tx key given to user which can be used to prove sending xmr to the recipient.
- Cross-Origin Resource Sharing (CORS) was disabled.
- Transaction confirmation window added to double check tx details before its commited.
or alternatively, owning to Gingeropolous:
This is Open Monero running on testnet network. You can use it to play around with it. Since this is testnet version, frequent changes and database resets are expected. Also, it is running on cheap vps, which may result in some lag.
If you want some testnet monero, please make issue with your testnet address that you can obtained from Open Monero.
The Open Monero consists of four components that need to be setup for it to work:
- MySql/Mariadb database - it stores user address (viewkey is not stored!), associated transactions, outputs, inputs and transaction import payments information.
- Frontend - it is virtually same as that of MyMonero, except before mentioned differences. It consists of HTML, CSS, and JavaScript.
- Monero daemon - daemon must be running and fully sync, as this is where all transaction data is fetched from and used. Daemon also commits txs from the Open Monero into the Monero network.
- Backend - fully written in C++. It uses restbed to serve JSON REST to the frontend and mysql++ to interface the database. It also accesses Monero blockchain and "talks" with Monero deamon.
Open Monero is not as fast as MyMonero. This is because it is basic, easy to understand and straight forward implementation of the backend. Thus, it does not use any catching of transactions, blocks, complex database structures and SQL queries. Also, no ongoing monitoring of user's transactions is happening, since viewkey is not stored. Transaction search threads start when user logs in (viewkey and address are submitted to the search thread), and finish shorty after logout. Once the search threads stop, they can't be restarted without user logging in back, because viewkey is unknown.
Below are example and basic instructions on how to setup up and run Open Monero on Ubuntu 16.04.
Download and compile recent Monero realease into your home folder:
# first install monero dependecines
sudo apt update
sudo apt install git build-essential cmake libboost-all-dev miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config libssl-dev libcurl4-openssl-dev libgtest-dev
# go to home folder
cd ~
git clone https://github.com/monero-project/monero
cd monero/
# checkout last monero version
git checkout -b last_release v0.10.3.1
makeOnce Monero was downloaded and compiled, we can download Open Monero and compile it. In fact we could postpone compilation to later, but we can just do it now, to see if it compiles. But don't run it yet. It will not work without database, setup frontend, and synced and running monero blockchain.
# need mysql++ libraries
sudo apt install libmysql++-dev
# go to home folder if still in ~/monero
cd ~
git clone https://github.com/moneroexamples/openmonero.git
cd openmonero
mkdir build && cd build
cmake ..
# altearnatively can use cmake -DMONERO_DIR=/path/to/monero_folder ..
# if monero is not in ~/monero
makesudo apt install mysql-server
sudo mysql_secure_installationDownload openmonero.sql provided and setup the openmonero database. openmonero.sql script will
drop current openmonero if exist. So don't run it, if you have already some important information
in the openmonero database.
Assuming we are still in build folder:
# apply it to mysql
mysql -p -u root < ../sql/openmonero.sqlsudo apt-get install lighttpdAssuming you are still in build folder, copy frontend source files into lighttpd www folder.
sudo mkdir /var/www/html/openmonero
sudo cp -rvf ../html/* /var/www/html/openmonero/Setup document root in lighttpd.conf into openmonero folder
sudo vim /etc/lighttpd/lighttpd.confand change server.document-root into:
server.document-root = "/var/www/html/openmonero"Restart lighttpd to see the change:
sudo systemctl restart lighttpdGo to localhost (http://127.0.0.1) and check if frontend is working.
Command line options
./openmonero -h
-h [ --help ] [=arg(=1)] (=0) produce help message
-t [ --testnet ] [=arg(=1)] (=0) use testnet blockchain
--do-not-relay [=arg(=1)] (=0) does not relay txs to other nodes.
useful when testing construction and
submiting txs
-p [ --port ] arg (=1984) default port for restbed service of
Open Monero
-c [ --config-file ] arg (=./config/config.json)
Config file path.Before running openmonero:
- make sure you have
Downloadsfolder in your home directory. Time library used in Open Monero stores there time zone offsets database that it uses. - edit
config/confing.jsfile with your settings. Especially setfrontend-urlanddatabaseconnection details. - set
apiUrlinhtml\js\config.jsandtestnetflag. Last slash/inapiUrlis important. If running backend for testnet network, frontendtestnetflag must be set totrue. For mainnet, it is set tofalse. - make sure monero daemon is running and fully sync. If using testnet network, use daemon with testnet flag!
To start for mainnet:
./openmoneroTo start for testnet:
./openmonero -tTo start for testnet with non-default location of config.json file:
./openmonero -t -c /path/to/config.jsIn the below examples, you can change 127.0.0.1:1984 into 139.162.32.245:1984 to
query the testnet open monero instance (assuming its up and working well).
