High-Level Build Configuration


This guide won't cover topics such as high availability, failover and resilience. If or how you build resilience into your design is a complex topic and there are many different ways it could be achieved. There is also a risk that including processes like automatic failover could cause double-signing of proposals which could at a future date lead to slashing.

We will be configuring two servers. In both cases there is an assumption you have already built the servers and are starting at a base Linux image level. There are plenty of guides and tutorials on the Internet on how to build and correctly configure an EC2 Instance which I won't provide here.

  1. The Radix Validator Node Server

  2. A Web Server for hosting Prometheus and Grafana

Node Server Hardware (AWS EC2)

  • c5.2xlarge

  • 8 vCPU

  • 16GB memory

  • 100GB of GP2 storage increasing in size as required

  • 10Gbps of Network bandwidth

  • Ubuntu LTS (Focal Fossa)

Node Server Software

  • Node exporter

  • fail2ban

  • Google authenticator 2FA

Web Server Hardware (AWS EC2)

  • t2.micro (AWS free-tier)

  • 1 vCPU

  • 1GB memory

  • 8GB storage (magnetic will be fine)

Web Server Software

  • Grafana

  • Prometheus

  • Nginx Web Server

  • Let’s Encrypt
