   cd /tmp/libsodium-1.0.12
   ./configure
   make
   make install
   rm -rf /tmp/libsodium-1.0.12

   export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
   ```
1. Build and install modern version of libzmq from sources:

   ```
   cd /tmp
   wget https://github.com/zeromq/libzmq/releases/download/v4.2.2/zeromq-4.2.2.tar.gz
   tar xfz zeromq-4.2.2.tar.gz && rm zeromq-4.2.2.tar.gz

      ```
      docker network create --subnet 10.0.0.0/8 pool_network
      docker build -f ci/sovrin-pool.dockerfile -t sovrin_pool .
      docker run -d --ip="10.0.0.2" --net=pool_network sovrin_pool
      ```
    * Run tests
      
      ```
      RUST_TEST_THREADS=1 cargo test
