Software Requirements​

Operating System​

OSSupported
Ubuntu 22.04 LTSRecommended
Ubuntu 20.04 LTSSupported
Debian 11+Supported
macOSDevelopment only

Dependencies​

# Ubuntu/Debian
sudo apt update
sudo apt install -y build-essential git curl jq

Storage Considerations​

Growth Rate​

Chain data grows over time:

  • Estimate: 10-50 GB/month (varies with activity)
  • Plan for 1+ year of growth
  • Monitor disk usage

Storage Type​

TypeSuitability
NVMe SSDBest
SATA SSDAcceptable
HDDNot recommended

Pruning​

Reduce storage with pruning:

# app.toml
pruning = "default"  # or "everything" for minimal
StrategyDescription
defaultKeep recent + snapshots
nothingArchive (no pruning)
everythingAggressive pruning

Network Requirements​

Ports​

PortProtocolPurpose
26656TCPP2P (required)
26657TCPRPC (optional)
26660TCPPrometheus (optional)
8545TCPEVM JSON-RPC (optional)
8546TCPEVM WebSocket (optional)
1317TCPREST API (optional)
9090TCPgRPC (optional)

Firewall​

Minimum:

# Allow P2P
sudo ufw allow 26656/tcp

# If exposing RPC
sudo ufw allow 26657/tcp

# Enable
sudo ufw enable

Validator-Specific​

Validators need additional considerations:

  • Static IP address
  • 99.9%+ uptime capability
  • Monitoring and alerting
  • Backup connectivity
  • Sentry nodes (recommended)
  • Key backup procedures

See Validator Requirements for full details.

FAQ​

Can I run on Raspberry Pi?

Not recommended. Insufficient resources for blockchain sync.

What about Docker?

Docker can be used for testing. For production, native installation with systemd is recommended.

How much bandwidth is needed?

Initial sync is bandwidth-intensive. Normal operation uses 10-50 Mbps.

Can I run multiple nodes on one server?

Possible but not recommended. Resource contention can cause issues.
