NYM mixnet

The NYM mixnet technology ensures enhanced privacy and anonymity for online communications. It utilizes a decentralized network to encrypt and route data, ensuring that the origin and destination are concealed. By implementing the NYM mixnet, users can protect their online activities and sensitive information, safeguarding their privacy from surveillance and censorship. This advanced networking technology provides a secure environment for transmitting data and maintaining anonymity.

Difficulty: Intermediate

The technology involves two key components: the Network Requester and the SOCKS5 Client. The Network Requester acts as an intermediary, encrypting and routing data through a decentralized mixnet network to enhance privacy and prevent surveillance. The SOCKS5 Client establishes a secure connection to the mixnet, enabling users to route network traffic and enjoy improved privacy.

Implementing these components empowers users to protect their online activities and sensitive information. Service providers, such as the network requester and mix nodes, offer services that leverage data mixing, identity protection, and traffic routing, further enhancing privacy in the NYM network.

Together, these components and service providers create a decentralized infrastructure within the NYM network, safeguarding user anonymity and protecting online activities.

Requirements

Preparations

Install dependencies

  • With user admin, make sure that all necessary software packages are installed

$ sudo apt install pkg-config build-essential libssl-dev jq

  • Check if you already have Rustc

$ rustc --version

Example of expected output:

> rustc 1.71.0 (8ede3aae2 2023-07-12)

  • And cargo installed

$ cargo -V

Example of expected output:

> cargo 1.71.0 (cfd3bbd8f 2023-06-08)

If you obtain "command not found" outputs, you need to follow the Rustup + Cargo bonus section to install it and then come back to continue with the guide

Configure Firewall

  • Stay login with the user admin, configure the firewall to allow incoming requests to the nym-socks5-client

$ sudo ufw allow 1080/tcp comment 'allow NYM socks5 client from anywhere'

Installation, Configuration & Run

Compile NYM binaries from the source code

  • Now we will go to the temporary folder to create the NYM binaries that we will need for the installation process

$ cd /tmp

  • Clone the latest version of the source code from the GitHub repository

$ git clone https://github.com/nymtech/nym.git

  • Enter to the nym folder

$ cd nym

  • Enter the command to compile

$ cargo build --release

This process can take quite a long time, 10-15 minutes or more, depending on the performance of your device. Please be patient until the prompt shows again

If the prompt shows you this error:

error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured. help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain.

You need to type "$ rustup default stable" and wait for the process to finish, then try again the command before

Also, that could help Upgrade Rust to the latest version

If you come to update, this is the final step, go back to the Upgrade section to continue

Install network Requester

Create the nym user

  • Create the user nym with this command

$ sudo adduser --gecos "" --disabled-password nym

  • Staying in the temporary folder, copy to the home nym user the "nym network requester" binary

$ sudo cp /tmp/nym/target/release/nym-network-requester /home/nym/

  • Assign the owner of the binary to the nym user

$ sudo chown nym:nym /home/nym/nym-network-requester

Init network requester

  • Switch to the user "nym"

$ sudo su - nym

  • Init the network requester for the first time with gateway based selection flag to choose a gateway based on its location relative to your device

$ ./nym-network-requester init --id bitcoin --latency-based-selection

If you want to select the gateway that your network requester will be connected to, you could add the flag --gateway <gatewayID> replacing the <gatewayID> with someone on this list and delete the --latency-based-selection flag

Example of expected output ⬇️

Take note of your network requester address <requesteraddress>

Example ->Address of this network-requester: 84K1SPBsSPGcCGQ6hK4AYKXuZHb5iU3zBc9gYb3cJp6o.Cfc67agMVw6GRjPb7ZyEfZSwLeVSvYtqKCKmATewujajT@2xU4CBE6QiiYt6EyBXSALwxkNvM7gqJfjHXaMkjhdjywS

Important! It is strongly advised not to share the address of your NYM service provider with anyone. Sharing this information could potentially involve you in illicit activities carried out by others using your network requester as a router. Please bear in mind that we operate in open proxy mode to avoid centralizing connections to concrete nodes of Bitcoin and servers of the other services. Safeguarding the confidentiality of your service provider address is essential to protect yourself and prevent any legal implications

Additionally, you can use the exit policy feature to avoid malicious connections using your network requester, by following the Use the exit policy feature

  • Check the correct installation

$ ./nym-network-requester -V

Example of expected output:

> nym-network-requester 1.1.24

  • Exit from the nym user session

$ exit

Create network requester systemd service

The system needs to run the network requester daemon automatically in the background, even when nobody is logged in. We use "systemd", a daemon that controls the startup process using configuration files.

  • As user admin, create the service file

$ sudo nano /etc/systemd/system/nym-network-requester.service

  • Paste the following configuration. Save and exit

# MiniBolt: systemd unit for nym network requester

Extras (optional)

Use the exit policy feature

Recently, NYM has introduced an option to publicly share your network requester (service provider address) and disallow all connections, minimizing the risk of your network requester being used to do malicious things. To achieve this, NYM uses a URL with an upstream source of the exit policy, to which a connection should be refused if trying to certain addresses (publicly recognized as malicious by different public reputation database sites). Important advice: this list could be deprecated and not include all of the malicious known addresses, so you could be allowing connections to malicious sites not included in it, acting under your responsibility.

  • With user admin, stop NYM socks5 client & NYM Network requester

$ sudo systemctl stop nym-socks5-client
$ sudo systemctl stop nym-network-requester

  • Edit the config.toml of the network requester

$ sudo nano /home/nym/.nym/service-providers/network-requester/bitcoin/config/config.toml

  • Change use_deprecated_allow_list = true to false. Save and exit

use_deprecated_allow_list = false

  • Edit the network requester systemd service

$ sudo nano /etc/systemd/system/nym-network-requester.service --linenumbers

  • Delete the --open-proxy true parameter on the line 13

ExecStart=/home/nym/nym-network-requester run --id bitcoin

  • Start the Nym network requester & Nym socks5 client again

$ sudo systemctl start nym-network-requester
$ sudo systemctl start nym-socks5-client

Now you can share your previously obtained service provider (network requester) address publicly, without exposing you so much as using the open-proxy feature

Proxying Bitcoin Core

So far, we have been routing all clearnet network traffic through Tor. However, it is also possible to proxy outbound clearnet connections (IPv4/IPv6) using the NYM mixnet. By doing this, we can reduce the volume of traffic on the Tor network.

  • With user admin, edit the bitcoin.conf file

$ sudo nano /data/bitcoin/bitcoin.conf

  • Modify the following line. Save and exit

# Connect to clearnet using NYM socks5 proxy
proxy=127.0.0.1:1080

  • Restart bitcoind to apply changes

$ sudo systemctl restart bitcoind

  • Check the correct proxy change network connection

$ bitcoin-cli getnetworkinfo | grep -A 3 ipv

Expected output:

      "name": "ipv4",
      "limited": false,
      "reachable": true,
      "proxy": "127.0.0.1:1080",
--
      "name": "ipv6",
      "limited": false,
      "reachable": true,
      "proxy": "127.0.0.1:1080",

If you have installed the NYM socks5 client installed in a machine inside of your local network, you can point the service to its IP address instead of localhost (127.0.0.1), e.g. 192.168.1.94:1080

NYM connect

NymConnect is an easy-to-use interface that enables you to connect other applications to the NYM mixnet for enhanced privacy. This desktop application allows you to effortlessly run the NYM SOCKS5 client without the need for manual commands.

Simply download the NYM Connect app for your operating system and click the prominent green button in the center of the screen. By default, the app automatically connects to a random gateway from a predefined list and utilizes a random service provider of this list.

These service providers grant access to specific applications such as Keybase, Telegram, Electrum, Monero Wallet, and Blockstream Green Wallet. However, it is worth noting the benefits of configuring your service provider with an "open proxy/exit policy" enabled. The previously configured Nym SOCKS5 client can run in the background as a daemon, commonly used in server operating systems without a desktop interface. Meanwhile, NYM Connect is typically utilized in desktop versions of operating systems.

If you wish to choose your gateway from the provided list or configure your service provider, you can do so by accessing the settings menu. Simply click on the hamburger icon located in the top-left corner -> Settings -> Select your gateway / Select your service provider using <requesteraddress> before configured

Upgrade

  • First, ensure that you have the latest Rustc version following the Upgrade section of the Rustup + Cargo bonus guide

  • Follow again the entire Compile NYM binaries from the source code section until the "Enter the command to compile" step (inclusive), once you do that, continue with the next steps below:

  • With admin user, stop NYM socks5 client & NYM Network requester

$ sudo systemctl stop nym-network-requester
$ sudo systemctl stop nym-socks5-client

Upgrade network requester

  • Replace the network requester binary

$ sudo cp /tmp/nym/target/release/nym-network-requester /home/nym/

  • Change to the nym user

$ sudo su - nym

  • Init again the network requester to update the config.toml file if needed

$ ./nym-network-requester init --id bitcoin --latency-based-selection

  • Check the correct update

$ ./nym-network-requester -V

Example of expected output:

> nym-network-requester 1.1.24

  • Exit from the nym user session

$ exit

  • Start network requester again

$ sudo systemctl start nym-network-requester

Upgrade socks5 client

  • Replace the socks5 client binary

$ sudo cp /tmp/nym/target/release/nym-socks5-client /home/nym/

  • Change to the nym user

$ sudo su - nym

  • Init again the socks5 client with the same command and service provider, this updates the config.toml file if needed

$ ./nym-socks5-client init --id bitcoin --latency-based-selection --provider <requesteraddress>

  • Check the correct update

$ ./nym-socks5-client -V

Example of expected output:

>  nym-socks5-client 1.1.24

  • Exit from the nym user

$ exit

  • Start socks5 client again

$ sudo systemctl start nym-socks5-client

  • Delete the NYM compilation folder to be ready for the next update and free up space

$ sudo rm -r /tmp/nym

Uninstall

  • With user admin, stop network requester and socks5 client services

$ sudo systemctl stop nym-network-requester
$ sudo systemctl stop nym-socks5-client

  • Delete network requester and socks5 client services

$ sudo rm /etc/systemd/system/nym-network-requester.service
$ sudo rm /etc/systemd/system/nym-socks5-client.service

  • Delete nym user. Don't worry about userdel: nym mail spool (/var/mail/nym) not found output, the uninstall has been successful

$ sudo userdel -rf nym

Troubleshooting

NYM is currently in development and may experience occasional issues.

If you encounter any issues, they may be related to the gateway. To resolve this, you can attempt to change the gateway by deleting the data folder.

Case NYM network requester issues:

  • With user admin, stop the network requester

$ sudo systemctl stop nym-network-requester

  • Change to the nym user

$ sudo su - nym

  • Init again network requester, by following the Init NYM network requester section, this time with --force-register-gateway and --gateway flags (remember deleting --latency-based-selection flag). Choose one gateway from this list, using its ID key

Example: ./nym-network-requester init --id bitcoin --gateway 2xU4CBE6QiiYt6EyFCSALwxKNvM7gqJfjHXaMkjiFmYW --force-register-gateway

Take note of the new "Address of this network-requester:..." to refresh it on socks5 clients are using this network requester ("--provider" flag)

  • Exit the nym user session to go back to the admin user

$ exit

  • Start network requester again

$ sudo systemctl start nym-network-requester

Case NYM socks5 client issues:

  • With user admin, stop the socks5 client

$ sudo systemctl stop nym-socks5-client

  • Change to the nym user

$ sudo su - nym

  • Init again the socks5 client by following the Init NYM socks5 client section, this time with --force-register-gateway and --gateway flags (remember deleting --latency-based-selection flag). Choose one gateway from this list, using its ID key. Remember to change the network requester address (service provider) if you change it at any moment

Example: ./nym-socks5-client init --id bitcoin --gateway 2xU4CBE6QiiYt6EyFCSALwxKNvM7gqJfjHXaMkjiFmYW --provider 84K1SPBsSPGcCGQ6hK4AYKXuZHb5iU3zBc9gYb3cJp6o.Cfc67agMVw6GRjPb7ZyEfZSwLeVSvYtqKCKmATewujajT@2xU4CBE6QiiYt6EyBXSALwxkNvM7gqJfjHXaMkjhdjywS --force-register-gateway

  • If you want to change only the service provider of your nym socks5 client connected, edit the config file and replace the provider_mix_address = parameter with the new one. With user nym. Save and exit

$ nano /home/nym/.nym/socks5-clients/bitcoin/config/config.toml
Example ⬇️
[core.socks5]

# The mix address of the provider to which all requests are going to be sent.
provider_mix_address = '84K1SPBsSPGcCGQ6hK4AYKXuZHb5iU3zBc9gYb3cJp6o.Cfc67agMVw6GRjPb7ZyEfZSwLeVSvYtqKCKmATewujajT@2xU4CBE6QiiYt6EyBXSALwxkNvM7gqJfjHXaMkjhdjywS'

  • Exit the nym user session to go back to the admin user

$ exit

  • Start socks5 client again

$ sudo systemctl start nym-socks5-client
