Metaverse(MVS) is a decentralised system based on the blockchain technology, through which, a network of smart properties, digital identities and value intermediators are established.
Metaverse on Blockchain Development Path:
Metaverse Features:
- Digital Assets Register/Transfering
- Digital Identity
- Decentralized Exchange
- Oralces and Offchain Data-feed
MVS is implemented based on libbitcoin project.

Dependencies of MVS are static linked (including libstdc++). Thus, there is no extra dependency after compilation. Recommends Ubuntu 16.04/CentOS 7.2/Visual Studio 2015 to develop/debug/build MVS.
- cmake 3.0+
- git
- automake (speck256k1/ZeroMQ required)
$ yum/brew/apt-get install git cmake
$ yum/brew/apt-get install autoconf automake libtool pkg-config$ git clone https://github.com/mvs-org/metaverse.git
$ cd metaverse && mkdir build && cd build
$ cmake ..
$ make -j4
$ make installIf you do not need UPnP support, you can use "cmake -DUSE_UPNP=OFF .." to disable it.
optional:
$ make test (should install boost_unit_test_framework)
$ make doc (should install doxygen and graphviz)Needs to configure Library Dependencies firstly.
Installing by bash script (sudo required).
$ sudo ./install_dependencies.shBy default, ./install_dependencies.sh will install ZeroMQ secp256k1.
You can install more by specify arguments, for example:
# --build-upnpc is needed is you want UPnP supporting.
$ sudo ./install_dependencies.sh --build-boost --build-upnpc$ sudo yum/brew/apt-get install libboost-all-devIf build boost manually, please download tar ball HERE.

Modules server/explorer required.
$ wget https://github.com/zeromq/libzmq/releases/download/v4.2.1/zeromq-4.2.1.tar.gz
$ tar -xzvf zeromq-4.2.1.tar.gz
$ cd zeromq-4.2.1
$ ./autogen.sh
$ ./configure
$ make -j4
$ sudo make install && sudo ldconfigModules blockchain/database required.
$ git clone https://github.com/mvs-live/secp256k1
$ cd secp256k1
$ ./autogen.sh
$ ./configure --enable-module-recovery
$ make -j4
$ sudo make install && sudo ldconfigSometimes we may meet the following compile error
undefined reference to '__gmpn_sub_n' ...
we may disable bignum in secp256k1 in this situation, use
$ ./configure --enable-module-recovery --with-bignum=no
and see more information here #issue209
Modules blockchain/network with UPnP function required.
$ wget http://miniupnp.tuxfamily.org/files/miniupnpc-2.0.tar.gz
$ tar -xzvf miniupnpc-2.0.tar.gz
$ cd miniupnpc-2.0
$ make -j4
$ sudo INSTALLPREFIX=/usr/local make install && sudo ldconfigAfter MVS is built successfully, there are two executable files in the bin directory:
-
mvsd - server program
Runs a full metaverse node in the global peer-to-peer network. -
mvs-cli - client program
Sent your request to the server, the server will process it and return response to your client.
Go to bin diretory, and run the program. More information please reference to Command line usage and Configuration file.
$ cd bin
$ ./mvsd
$ ./mvs-cli $command $params $optionsInstall Docker.
