How to run a Venom validator node



The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.


Running a Validator node makes you responsible for your entire stake. If something goes wrong, the node could be slashed, and you can lose your stake.

You SHOULD have enough Linux engineering skills to manage, secure, and maintain nodes. Running a Validator node is considerably more advanced than executing a validator binary.



To operate a Validator node, a sufficient quantity of Venom tokens is required. The node can be deployed in either validator or DePool mode.

Node hardware minimums

CPU: 12x cores Intel Skylake or a newer CPU. The higher base CPU frequency is preferred over a core count;

RAM: 64GB; Network: 300Mbps with a reliable internet connection. Connection issues can potentially cause slashing of your Validator;


50GB SSD storage for the operating system; 500GB of NVMe for Validator internal database, with the ability to add additional space to allow for the the growth of the blockchain;

Operating system: Ubuntu 22.04

These specs are not a hard requirement, but rather a best practice. Because running a validator node is a consequential task, you should consider using enterprise-grade hardware, to ensure the stability of your node.

Cloud providers


Beware of the Terms and conditions of the cloud provider of your choice. DigitalOcean’s Acceptable User Policy requires implicit permission to undertake "mining of cryptocurrencies" and this may be extended to other cryptocurrency activities.

Successfully tested Cloud Providers:

  • Google Cloud
  • Amazon AWS
  • Microsoft Azure
  • OVH

To make your node work properly, configure the cloud firewall to accept incoming traffic on UDP/30000 port


The node will consume approximately 6TB of incoming traffic each month. You should consider this when estimating the costs of your setup.

Node setup


Always check any scripts you are running

  1. Prepare the server for node setup

1.1. Create a user and group for running the Validator node, and create all necessary folder structures

sudo groupadd $VALIDATOR_GROUP
sudo useradd $VALIDATOR_USER -m -s /bin/bash -g $VALIDATOR_GROUP -G sudo
# Mount
sudo mkdir -p /var/venom/rnode/
sudo chown $VALIDATOR_USER:$VALIDATOR_GROUP /var/venom/rnode/

1.2. Check if the NTP service is UP and running

systemctl status systemd-timesyncd

Your system should show that the service is up and running. If not - please refer to the documentation

● systemd-timesyncd.service - Network Time Synchronization
Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled;
preset: enabled)
Active: active (running)

If the system clock is out of sync (even by a small amount), the blocks which the Validator produces, may not be accepted by the network.

  1. Create firewall rules to allow ADNL communications
sudo ufw allow 30000/UDP
  1. Install dependencies
sudo apt update 
sudo apt install -y git libssl-dev pkg-config build-essential libzstd-dev
libclang-dev libgoogle-perftools-dev
  1. Switch to the validator user
sudo su validator

4.1 Install rust

curl -sSf | sh
source "$HOME/.cargo/env"
  1. Build a Validator node

cargo install --locked --git
# Enable validator services
sudo $PWD/.cargo/bin/stvenom init systemd

Here choose the user for the validator. DON'T RUN Validator service as a root user!

6.1 Define the desired stake per round. Notice you will need an amount of tokens 2*(stake per round)+10

Leave "stake factor (ratio between maximum available stake on the network and your stake) to 3 as it is standard in the Venom network

✔ Stake per round (VENOM) · 10000
✔ Stake factor · 3
[2/2] Validator configured successfully. Great!

Validator wallet address:

Required validator wallet balance: 20010 VENOM
10 VENOM, maintenance balance
2 x 20010 VENOM, stakes for each round

Make sure you back up your keys:

Make sure you back up your keys after the initial configuration! All keys are stored at $HOME/.stvenom/keys/

Init validator services

sudo ~/.cargo/bin/stvenom init systemd

Service MUST NOT run as the root user

❯ validator

It will create two services:

  • venom-validator-manager - control service that takes part in elections, recovers stake and performs other tasks with the Elector contract
  • venom-validator - node itself, managing validation process

You can check the status of both services with the following commands:

service venom-validator status
service venom-validator-manager status
  1. Transfer tokens to the Validator contract

Transfer the required amount of tokens to the address generated in the previous step. The Wallet will become active after the first stake

  1. Wait until the elections start

When elections start, the venom-validator-manager process will automatically stake the desired amount of tokens. You can check the current state of elections using


venom-validator-manager adds 1 VENOM token for the stake to pay for the transaction fees, and you will be required to add 1 VENOM token to the "stake and bonuses recovery" transaction. Due to this, it is adviseable to always keep some additional tokens in the Validator

If everything has been setup correctly - you should see your address in the validators list for the next round.
