Ethereum: Node synchronization stopped

Ethereum Node Synchronization Broken: Troubleshooting Guide

Suddenly losing node synchronization on the Ethereum network can be a cause for concern, especially for developers who rely on real-time data and communication between nodes. In this article, we will delve into the possible causes and solutions for the broken synchronization process in Sepolia RPC (Relay Pool System) nodes.

What is Node Synchronization?

Node synchronization refers to the process of updating each node’s copy of the blockchain, ensuring that all nodes have the same state at any given time. This ensures the integrity and reliability of the network, preventing single points of failure.

Common reasons for broken synchronization:

• Network issues:

  Poor connectivity or latency between nodes can cause a broken synchronization.

• Data Storage Issues:

  Improper configuration, corrupted data storage, or insufficient storage capacity on each node can cause sync issues.

• Software Updates: Outdated node software or firmware can cause compatibility issues and prevent syncing.

Troubleshooting steps for broken sync:

• Check network connectivity: Ensure all nodes are connected to the same network and have a stable internet connection.

• Check data storage configuration: Review the data storage settings on each node, including the configuration file (e.g. sepolia.conf) and ensure it is set up correctly for syncing.

• Update node software: Install Sepolia RPC firmware updates to ensure compatibility with the latest versions of the Ethereum client.

Sepolia RPC Configuration:

For those unfamiliar with Sepolia RPC, here are some relevant configuration options:

• Network ID: Set to 11155111 (or another value if the network ID is different).

• Data Storage: Select Bonsai as the data storage type.

• Relay Pool Size: Adjust this setting based on the number of nodes participating in the RPC.

Best practices for node synchronization:

• Back up data regularly: Ensure that all node backups are properly backed up and are periodically verified for integrity.

• Monitoring network traffic: Monitor network traffic patterns and latency to identify potential synchronization issues.

Conclusion:

A combination of factors can cause the synchronization process to fail on Sepolia RPC nodes. By following the troubleshooting steps above, you should be able to resolve the issue and get your node back to syncing. Remember to back up your data regularly and monitor your network traffic for optimal performance.
