Running a node on the OKT Chain (OKTC) is a foundational step for participants who want to contribute to network security, decentralization, and performance. Whether you're setting up a Validator Node, Full Node, or Archive Node, understanding the precise hardware and configuration requirements is essential for maintaining reliability and efficiency. This guide provides a comprehensive breakdown of the technical specifications, best practices, and optimization strategies to ensure your node operates smoothly within the OKTC ecosystem.
Minimum Hardware Configurations
To maintain network integrity and performance, OKTC defines clear minimum hardware standards for each node type. These configurations are designed to support the blockchain’s growing data demands and ensure fast, secure transaction validation.
Validator Node
A Validator Node plays a critical role in consensus by proposing and attesting to new blocks. Due to its high responsibility, it requires the most robust setup.
- CPU: 3.5 GHz, 16-Core
- Architecture: x86_64
- RAM: 64 GB
- Storage: 1 TB SSD
- Bandwidth: 100 Mbps
- Recommended Cloud Instance: AWS m6i.4xlarge (16 cores, 64 GB RAM, 3.5 GHz)
Full Node
Full Nodes synchronize the entire blockchain and validate transactions independently. While not involved in block production, they are vital for network redundancy and data availability.
- CPU: 3.0 GHz or higher, 16-Core
- Architecture: x86_64
- RAM: 64 GB
- Storage: 1 TB SSD
- Bandwidth: 100 Mbps
- Recommended Cloud Instance: AWS m6i.4xlarge
Archive Node
Archive Nodes store the complete historical state of the blockchain, making them essential for analytics, indexing services, and advanced queries.
- CPU: 3.0 GHz or higher, 16-Core
- Architecture: x86_64
- RAM: 64 GB
- Storage: 5 TB SSD (expandable based on chain growth)
- Bandwidth: 100 Mbps
- Recommended Cloud Instance: AWS r6i.4xlarge
💡 As the OKT Chain continues to grow, storage demands will increase over time. It's strongly advised to exceed minimum storage requirements—especially for Full and Archive Nodes—to ensure long-term stability and avoid sync issues.
Key Considerations for Node Performance
While meeting baseline hardware specs is crucial, real-world performance depends heavily on storage type, disk I/O speed, and network configuration.
Why Disk Performance Matters
OKTC nodes use LevelDB to store both block data and state information. This database engine performs frequent read and write operations, making disk speed a critical factor in node responsiveness. Slow disks can cause delays in block synchronization, increasing the risk of falling behind the chain tip—especially during high network activity.

Common Issues with Cloud Storage
One of the most frequent challenges faced by node operators involves suboptimal cloud disk selection. For example:
Using standard cloud disks from providers like Alibaba Cloud—such as Ultra Disks—can lead to significant synchronization lag due to lower IOPS (Input/Output Operations Per Second) and higher latency.
These disks are often cost-effective but lack the throughput needed for intensive blockchain workloads.
Recommended Storage Solutions
To ensure optimal performance, especially on cloud platforms, it's essential to choose high-speed storage options.
Alibaba Cloud Disk Types
Alibaba Cloud offers four main types of cloud disks:
- Standard SSD
- Ultra Disk
- ESSD (Enhanced SSD)
- ESSD AutoPL Disk
Among these, Standard SSD is recommended for both Alibaba Cloud and AWS-based nodes due to its balanced performance, reliability, and cost-efficiency.
While ESSD offers superior performance, Standard SSD provides sufficient IOPS for most node operations without unnecessary overhead.
For environments requiring extreme throughput (e.g., Archive Nodes under heavy query load), upgrading to ESSD may be justified.
Best Practices for Running a Stable Node
Beyond hardware, several operational practices enhance node uptime and responsiveness:
- Monitor Disk Usage Regularly
Set up alerts for disk utilization to avoid running out of space during peak chain growth. - Use Static Public IP Addresses
Ensures consistent peer connectivity and improves discoverability on the network. - Enable Firewall Rules Selectively
Only open required ports (e.g., P2P, RPC) and restrict access where possible to reduce attack surface. - Keep Software Updated
Regularly update your node software to benefit from bug fixes, performance improvements, and security patches. - Back Up Critical Keys and Configs
Store validator keys securely using hardware modules or encrypted vaults.

Frequently Asked Questions
What happens if my node falls behind in synchronization?
If your node lags behind the latest block height, it may serve outdated data or fail to validate new blocks correctly. This can disrupt services like API access or staking operations. To recover, restart synchronization using snapshot recovery tools or resync from a recent backup.
Can I run multiple node types on the same machine?
Technically yes—but not recommended. Running a Validator alongside an Archive Node on the same hardware risks resource contention, especially under load. For reliability, isolate critical roles onto separate machines.
Is there a difference between SSD types across cloud providers?
Yes. While both AWS and Alibaba Cloud offer SSD options, their underlying architecture and IOPS performance vary. AWS gp3 and Alibaba Cloud Standard SSD are comparable in mid-tier performance. Always benchmark disk performance before deployment.
Do I need more than 64GB RAM for future-proofing?
Currently, 64GB meets requirements even under peak load. However, as state bloat increases over time, upgrading to 128GB may become beneficial—especially for Archive Nodes handling complex queries.
Can I use HDD instead of SSD?
No. HDDs lack the random read/write speed necessary for LevelDB operations. Using HDD storage will result in severe performance degradation and likely cause your node to fall out of sync permanently.
How often should I upgrade my storage?
Monitor chain growth trends—currently around 50–100 GB per month depending on activity. Plan storage upgrades proactively every 6–12 months for Archive Nodes; Full Nodes may require less frequent expansion.
Final Thoughts
Successfully operating a node on OKT Chain requires more than just meeting minimum specs—it demands thoughtful infrastructure planning, ongoing maintenance, and awareness of evolving network demands. By selecting high-performance SSD storage, monitoring system health, and following best practices, you can ensure your node remains a reliable part of the decentralized network.
Whether you're securing the network as a validator or supporting data availability as a full node operator, your contribution strengthens the entire ecosystem.
