The mixnet code is relatively simple to build and run on Mac OS X and Linux. We haven't tried it on Windows (yet).


  • Rust 1.39 or later, with Cargo. Stable works.
  • on Debian/Ubuntu: sudo apt install pkg-config build-essential libssl-dev

To download and build:

git clone
git checkout tags/v0.3.2
cd nym
cargo test # runs unit and integration tests
cargo build --release # if you want binaries to try out

The above commands will check the code out from Github, and then compile three pieces of software into the target/release directory:

ls target/release/

build	     libnym_client.d		    nym-client	   nym-sfw-provider
deps	     libnym_client.rlib		    nym-client.d   nym-sfw-provider.d
examples     libsfw_provider_requests.d     nym-mixnode
incremental  libsfw_provider_requests.rlib  nym-mixnode.d

Quite a bit of stuff gets built, but you can ignore most of it. The mixnet parts are:

  1. the Nym mixnode, nym-mixnode
  2. the Nym store-and-forward provider node, nym-sfw-provider
  3. the Nym client, nym-client

In the next sections we'll try each of these out.
