Hardware Requirements​

Please note the following are the hardware requirements for each node type after the upgrade:

Software​

Supported environments include macOS, Linux (Debian 10, 11 and Ubuntu 20.04 LTS), and any host machine with Docker. Only x86-64 CPU architecture is supported.

Clock Synchronization​

Your server must run a clock synchronization protocol such as NTP to participate in consensus. Most Linux distributions include NTP by default.

o1Labs has tested running nodes on several cloud providers. We recommend the following instances for basic node operator needs. Custom requirements and different cost constraints might require a different instance type.

Networking​

IP: By default, the Mina daemon determines its public IP address automatically via HTTPS (443) and HTTP (80). If you are behind a NAT or firewall, set the --external-ip flag to specify your public IP address.

Port: Nodes must expose a port to communicate with peers. The default is TCP port 8302. You can change it with the --external-port flag.

Firewall and port forwarding: Allow inbound traffic on the following ports through your external IP address:

  • TCP port 8302 (required for peer communication)
  • TCP port 3085 (optional, for the GraphQL API)

If you are using UFW:

sudo ufw enable
sudo ufw allow 22
sudo ufw allow 8302
sudo ufw allow 3085
