Introduction

In the context of blockchain networks, validating genesis blocks is a crucial process that ensures the integrity and consistency of the network. When a network change occurs, it is essential to validate the genesis block to determine whether the change is within the same network or a new one. This article will delve into the importance of validating genesis blocks on network change and explore a potential solution to address this issue.

Understanding Genesis Blocks

A genesis block is the first block in a blockchain, which serves as the foundation for the entire network. It contains essential information such as the network's initial state, the creator of the block, and the timestamp. The genesis block is a critical component of the blockchain, as it determines the network's architecture and rules.

Network Change and Genesis Block Validation

When a network change occurs, it is essential to validate the genesis block to determine whether the change is within the same network or a new one. A network change can be triggered by various factors, such as a change in the full node or a switch to a new network. However, not all network changes require a full reset of the registered tokens and nano contracts.

The Issue with Current Implementation

After issue #660, all registered tokens and nano contracts are cleared from the app when the network is changed. However, this implementation has a flaw. It does not account for network changes within the same network, such as changing the full node from node1.mainnet to node2.mainnet. This is an edge case of the issue raised by #385.

Proposed Solution

To address this issue, we can implement a solution that reads the hashes of the genesis block obtained from the full node status request and compares it to the previous network. If both are the same, we can assume the network hasn't changed, and the registered data cleanup should not occur.

Benefits of Genesis Block Validation

Validating genesis blocks on network change offers several benefits, including:

Improved Network Integrity: By validating the genesis block, we can ensure that the network remains consistent and intact, even in the face of changes.
Reduced Data Loss: By not clearing registered tokens and nano contracts unnecessarily, we can reduce data loss and minimize the impact of network changes.
Enhanced User Experience: By providing a more seamless and efficient experience, we can improve user satisfaction and engagement.

Implementation Details

To implement this solution, we can follow these steps:

Read the Genesis Block Hash: Use the full node status request to obtain the hash of the genesis block.
Compare with Previous Network: Compare the obtained hash with the previous network's hash to determine whether the network has changed.
Determine Cleanup: If the network has not changed, do not clear registered tokens and nano contracts.

Conclusion

Validating genesis blocks on network change is a critical process that ensures the integrity and consistency of the network. By implementing a solution that reads the hashes of the genesis block and compares it to the previous network, we can address the issue of unnecessary data cleanup and provide a more seamless experience for users. By following the proposed implementation details, we can improve network integrity, reduce data loss, and enhance user experience.

Future Work

While this solution addresses the issue of network changes within the same network, there may be other edge cases that require further investigation. Future work may include:

Exploring Additional Edge Cases: Investigate other potential edge cases that may require special handling.
Improving the Validation Process: Refine the validation process to ensure that it is more efficient and accurate.
Enhancing User Experience: Continue to improve the user experience by providing a more seamless and efficient experience.
