| Specification | Validator Node | Full Node | Archive Node |
|---|---|---|---|
| CPU | 3.5 GHz, 16-Core | 3.0 GHz or up, 16-Core | 3.0 GHz or up, 16-Core |
| System Architecture | x86_64 | x86_64 | x86_64 |
| RAM | 64GB | 64GB | 64GB |
| Storage | 1TB SSD | 1TB SSD | 5TB SSD (Expandable) |
| Bandwidth | 100Mbps | 100Mbps | 100Mbps |
| Cloud Recommendations | AWS m6i.4xlarge | AWS m6i.4xlarge | AWS r6i.4xlarge |
💡 Pro Tip: Storage requirements increase as the network grows. For reliable operation, always exceed minimum specifications.

Best Practices for Node Operation
Understanding Storage Requirements
Blockchain nodes utilize LevelDB for storing both block data and state data. This creates significant disk I/O operations, making storage performance crucial for node synchronization and operation.
Common Performance Challenges
Many operators experience synchronization delays when using standard cloud storage solutions. Our tests show:
- Standard cloud disks cause 15-30% slower block synchronization
- Latency spikes during peak network activity
- Increased resource consumption during catch-up phases
Recommended Storage Solutions
For optimal performance on major cloud platforms:
- Alibaba Cloud Options:
- ESSD AutoPL disks (best performance)
- Enhanced SSDs (balanced option)
-
Standard SSDs (entry-level)
-
AWS Recommendations:
- io1 or io2 volumes for high throughput
- gp3 volumes for cost-effective performance
- Avoid standard magnetic storage

Advanced Node Optimization Techniques
Memory Management Strategies
While 64GB meets minimum requirements, consider these optimizations:
- Validator Nodes: Increase to 128GB during major network upgrades
- Archive Nodes: Implement tiered storage with hot/cold data separation
- Full Nodes: Adjust cache sizes based on transaction volume
Network Configuration Tips
- Dedicate at least 25% of bandwidth to peer connections
- Configure QoS rules to prioritize consensus messages
- Implement monitoring for packet loss and latency
Maintenance Best Practices
- Regular health checks (at least weekly)
- Automated backup routines
- Performance benchmarking after configuration changes
- Security patching schedule
Frequently Asked Questions
Q: Can I run a node with less than the recommended hardware?
A: While possible, suboptimal hardware leads to synchronization issues and potential slashing penalties for validators. Always meet or exceed requirements.
Q: How often should I upgrade my node hardware?
A: Re-evaluate your setup every 6-12 months as network requirements evolve. Monitor performance metrics for upgrade signals.
Q: What’s the biggest performance bottleneck for nodes?
A: Storage I/O proves most critical in 80% of cases. Invest in high-performance SSDs before upgrading other components.
Q: Can I use consumer-grade hardware for node operation?
A: For test networks or development purposes only. Production nodes require enterprise-grade reliability and performance.
Q: How do I monitor my node’s performance effectively?
A: Implement monitoring for: block sync time, CPU/memory usage, disk latency, and network throughput. Set up alerts for anomalies.
Q: Are there different requirements for different blockchain networks?
A: Yes, requirements vary significantly. Always consult the specific network’s documentation before deployment.
