Technical Requirements

Based on early tests, validator node requirements include:

  • Operating system:
    • Planning on running from docker: Any linux based system capable of running docker
    • Planning on running from source: Ubuntu 20.04 LTS
  • CPU:
    • Intel, AMD or ARM based processor 3.0 GHz or above with 2 cores or equivalent
    • In testnet, scores of GeekBench 5 Multi-Core of greater than 2,200 have performed well
    • For Intel and AMD systems, AVX2 or AVX support is required. Verify your CPU supports these extensions by checking grep avx /proc/cpuinfo and verifying that AVX support is included in the output.
    • These recommendations may change for mainnet as the size of consensus groups grow and hotspot transactions are added
  • Memory: 8 GB or above
  • Storage: 256 GB or more for mainnet. 64GB is sufficient for testnet.
  • If using AWS, a t2.large or t2.xlarge EC2 instance or equivalent is recommended. If using another cloud provider, like GCP, Azure, or Digital Ocean, an instance with similar capabilities should be the target.
  • Static IP address with port 2154(TCP) opened in your firewall with a route available to your validator host.
  • Running on stable network connection free of things like proxies, NAT, etc. The load is largely symmetrical when producing blocks, so good upstream connectivity recommended.
  • It is discouraged to run Validators at home.
