Minimum Hardware Configurations
Running a blockchain node requires specific hardware to ensure smooth operation. Below are the minimum hardware configurations for different node types:
| Node Type | CPU Requirements | RAM | Storage | Bandwidth | Suggested Cloud Instance |
|---|---|---|---|---|---|
| Validator Node | 3.5 GHz, 16-Core | 64G | 1T SSD | 100M | AWS m6i.4xlarge |
| Full Node | 3.0 GHz or higher, 16-Core | 64G | 1T SSD | 100M | AWS m6i.4xlarge |
| Archive Node | 3.0 GHz or higher, 16-Core | 64G | 5T SSD (Expandable) | 100M | AWS r6i.4xlarge |
💡 Pro Tip: Storage needs increase as the network grows. Exceeding minimum specs ensures long-term stability.

Node Operation Recommendations
Understanding Storage Challenges
OEC nodes utilize LevelDB for storing block and state data. This design imposes significant disk I/O demands, making storage performance critical.
Common Performance Issues
Many users report synchronization delays when using standard cloud disks (e.g., Alibaba Cloud's basic offerings). These typically occur because:
- Insistent read operations overwhelm disk throughput
- I/O bottlenecks create block processing delays
- Suboptimal disk types fail to meet LevelDB's random access patterns
Optimal Storage Solutions
For cloud deployments, consider these storage options:
Standard SSDs (Recommended)
- Balanced price-to-performance ratio
- Suitable for most node operations
- Available across major cloud providers
ESSD/Ultra Disks (For High-Throughput Needs)
- Higher IOPS capabilities
- Better for archive nodes or high-traffic networks

Frequently Asked Questions
What happens if I use HDD instead of SSD?
HDDs cannot meet the random access requirements of LevelDB, leading to severe synchronization delays and potential node failures.
How often should I upgrade node storage?
Monitor your storage utilization monthly. As a rule of thumb, upgrade when usage reaches 70% of capacity.
Can I run a validator node on less than 16 cores?
While possible, fewer cores may result in missed blocks during peak network activity, affecting your validator rewards.
Is local hardware viable for node operation?
Yes, but ensure your setup meets or exceeds the cloud equivalent specs, particularly for storage speed and bandwidth.
Why does bandwidth matter for full nodes?
Nodes constantly exchange block data with peers. Limited bandwidth slows data propagation, potentially affecting network participation.
