Node Requirements for Running on OKTC

·

Running a node on the OKT Chain (OKTC) network is a critical step for participants who want to contribute to the blockchain’s decentralization, security, and performance. Whether you're setting up a Validator Node, Full Node, or Archive Node, understanding the precise hardware and system requirements is essential for ensuring stable and efficient operation. This guide outlines the minimum configurations, best practices, and technical considerations for deploying and maintaining a high-performance node on OKTC.

Minimum Hardware Configurations

To operate any type of node on the OKTC network—be it a Validator, Full, or Archive Node—your infrastructure must meet specific baseline hardware standards. These ensure that your node can handle blockchain data synchronization, transaction validation, and real-time consensus participation without performance degradation.

Below are the minimum hardware requirements for each node type:

Full Node

Archive Node

💡 Note: As the OKTC network grows, storage demands will increase over time. It’s strongly advised to exceed minimum storage specifications—especially for Full and Archive Nodes—to ensure long-term stability and avoid sync delays.

While these are minimum thresholds, running nodes with upgraded specs (e.g., faster NVMe SSDs, increased RAM headroom) significantly improves resilience during peak network activity and reduces the risk of falling out of sync.

Technical Background: Why Disk Performance Matters

OKTC nodes utilize LevelDB as the underlying database engine to store both block data and state information. LevelDB is optimized for fast key-value writes and reads but places substantial I/O demands on storage systems—especially during block propagation and state synchronization.

Because nodes constantly read from and write to disk during normal operations, disk performance becomes a critical bottleneck if not properly addressed. Slow or inconsistent disk I/O can result in:

This makes high-performance solid-state storage not just a recommendation—but a necessity.

Common Issues with Standard Cloud Disks

Many users initially opt for standard cloud storage solutions to reduce costs. However, this often leads to operational challenges.

For example, using ordinary cloud disks on platforms like Alibaba Cloud—such as basic ultra disks or shared storage tiers—can severely impact node performance. These disk types typically offer:

As a result, nodes may experience:

These issues compromise not only your node’s reliability but also its ability to contribute meaningfully to the network.

Recommended Storage Solutions

To avoid performance pitfalls, it’s crucial to select the right type of cloud storage. On major providers like Alibaba Cloud, four primary disk types are available:

  1. Standard SSD
  2. Ultra Disk
  3. ESSD (Enhanced SSD)
  4. ESSD AutoPL Disk

Among these, Standard SSD is the recommended choice for both Alibaba Cloud and AWS environments when running OKTC nodes.

Why Choose Standard SSD?

While ESSD disks offer even better performance, they come at a higher cost. For most Full and Validator Nodes, Standard SSD delivers optimal efficiency without overspending.

For Archive Nodes—which store complete historical data and require extensive disk throughput—consider upgrading to ESSD or high-tier NVMe-backed storage if budget allows.

Best Practices for Running OKTC Nodes

Beyond hardware specs, successful node operation depends on strategic configuration and monitoring. Follow these recommendations to maximize uptime and efficiency:

1. Use Dedicated Instances

Avoid sharing resources with other applications. Run your node on a dedicated virtual machine or bare-metal server to prevent CPU or memory contention.

2. Monitor Disk I/O Regularly

Implement monitoring tools (e.g., iostat, Prometheus + Grafana) to track disk utilization and latency. Set alerts for abnormal spikes that could indicate sync issues.

3. Enable Automatic Backups

Schedule regular snapshots of your node’s data directory—especially for Validator Nodes—to enable quick recovery in case of failure.

4. Keep Software Updated

Regularly update your oktc client software to benefit from bug fixes, performance improvements, and protocol upgrades.

5. Secure Your Node

Use firewalls to restrict access to essential ports only. Disable root login and use SSH key-based authentication for secure remote management.

Frequently Asked Questions (FAQ)

Q: Can I run an OKTC node on consumer-grade hardware?
A: While technically possible, consumer hardware often lacks the sustained I/O performance and RAM capacity needed for reliable operation. For production use—especially as a validator—cloud-based or enterprise-grade systems are strongly recommended.

Q: What happens if my node falls behind in synchronization?
A: A delayed node may miss block proposals or fail to validate transactions in time. Validators risk being penalized (slashed) if downtime exceeds thresholds. Regular maintenance and robust hardware help prevent this.

Q: Is there a difference between Full Nodes and Archive Nodes beyond storage size?
A: Yes. Full Nodes store recent state data sufficient for validating current transactions, while Archive Nodes retain complete historical chain data, enabling advanced queries and analytics.

Q: How often should I upgrade my node's storage?
A: Monitor free space monthly. Plan upgrades proactively when utilization exceeds 70%. For Archive Nodes, expect annual storage growth depending on network activity.

Q: Can I switch from a Full Node to a Validator Node later?
A: Yes—but you must meet validator eligibility criteria, including staking requirements and signing up through the OKTC consensus system.
