## Validator Setup

The Validator setup is composed of MasterNode which is used to manage deployments via Ansible and Regular Nodes that are instanciated as PolkaDot Validators. All communication between Nodes happens via Secure Shell Protocol (SSH). 

For more details regarding the setup, see the diagram below.

* Our validator is setup based on the secure polkadot repo: https://github.com/w3f/polkadot-validator-setup with minor configurations.
* Running Polkadot validators since August 2021 with no downtime.
* Running a validator from VPS in Latvia from underrepresented cloud provider.
* Implemented Validator Monitoring Dashboard through Grafana on linux instance: http://80.208.228.61:3000/login 

#### Security Policies 
* Used NGNIX Reverse Proxy
* Encripted key-based SSH access instead of password-based access.
* Not using root user on Ubuntu 18.04 but creating new user.
* Software firewall setup.
* only allow the proxy, SSH and node-exporter ports. 
    

Strategy for Attracting Nominators
* Low or zero commission.
