Understanding the Importance of Submitting Missed L2 Blocks

In the context of blockchain development, particularly in the Taiko network, submitting missed L2 blocks or previous preconfer is a crucial step to ensure the integrity and accuracy of the network. This process involves checking for gaps between the L2 head in the taiko-client and the first block in the batch, and submitting any L2 blocks that were previously preconfed but not timely submitted to L1 by the preceding preconfer.

What are L2 Blocks and Preconfer?

Before diving into the details of submitting missed L2 blocks or previous preconfer, it's essential to understand what L2 blocks and preconfer are.

L2 Blocks: L2 blocks refer to the blocks that are generated on the second layer of the blockchain, which is typically responsible for processing transactions and updating the state of the network.
Preconfer: Preconfer is the process of submitting a batch of L2 blocks to the L1 (first layer) of the blockchain for validation and confirmation.

Why is Submitting Missed L2 Blocks or Previous Preconfer Important?

Submitting missed L2 blocks or previous preconfer is essential for several reasons:

Maintaining Network Integrity: By submitting missed L2 blocks or previous preconfer, you ensure that the network remains intact and accurate. Any gaps or missing blocks can lead to inconsistencies and errors in the network.
Preventing Double Spending: Submitting missed L2 blocks or previous preconfer helps prevent double spending, which occurs when a user attempts to spend the same funds twice.
Ensuring Consensus: By submitting missed L2 blocks or previous preconfer, you help ensure that the network reaches consensus, which is critical for the functioning of the blockchain.

How to Submit Missed L2 Blocks or Previous Preconfer

To submit missed L2 blocks or previous preconfer, follow these steps:

Step 1: Check for Gaps

Before submitting your first batch to L1, preconfers should check for gaps between the L2 head in the taiko-client and the first block in their batch. If a gap exists, proceed to the next step.

Step 2: Submit Previous Preconfer

If a gap exists, you must first submit any L2 blocks previously preconfed (present at the taiko-client's head) that weren't timely submitted to L1 by the preceding preconfer.

Step 3: Submit Missed L2 Blocks

Once you have submitted the previous preconfer, you can submit the missed L2 blocks. This involves submitting the blocks that were previously preconfed but not timely submitted to L1.

Step 4: Verify and Confirm

After submitting the missed L2 blocks or previous preconfer, verify and confirm that the blocks have been successfully submitted and processed by the network.

Best Practices for Submitting Missed L2 Blocks or Previous Preconfer

To ensure a smooth and efficient process, follow these best practices:

Regularly Check for Gaps: Regularly check for gaps between the L2 head in the taiko-client and the first block in your batch to prevent missing blocks.
Submit Previous Preconfer First: Always submit the previous preconfer before submitting the missed L2 blocks to ensure that the network remains intact.
Verify and Confirm: Verify and confirm that the blocks have been successfully submitted and processed by the network to ensure accuracy and integrity.

Q&A: Submitting Missed L2 Blocks or Previous Preconfer

Frequently Asked Questions and Answers

Q: What is the purpose of submitting missed L2 blocks or previous preconfer?

A: The purpose of submitting missed L2 blocks or previous preconfer is to ensure the integrity and accuracy of the blockchain network. By submitting missed L2 blocks or previous preconfer, you help maintain the network's consistency and prevent errors.

Q: Why is it essential to submit previous preconfer before submitting missed L2 blocks?

A: It's essential to submit previous preconfer before submitting missed L2 blocks because it ensures that the network remains intact and accurate. Submitting previous preconfer first helps prevent double spending and ensures consensus.

Q: How do I check for gaps between the L2 head in the taiko-client and the first block in my batch?

A: To check for gaps, you can use the following steps:

Check the L2 head in the taiko-client.
Check the first block in your batch.
Compare the two to see if there is a gap.

Q: What happens if I don't submit missed L2 blocks or previous preconfer?

A: If you don't submit missed L2 blocks or previous preconfer, it can lead to inconsistencies and errors in the network. This can result in double spending, which can have severe consequences for the network and its users.

Q: Can I submit missed L2 blocks or previous preconfer manually?

A: Yes, you can submit missed L2 blocks or previous preconfer manually. However, it's recommended to use the automated process to ensure accuracy and efficiency.

Q: How do I verify and confirm that the blocks have been successfully submitted and processed by the network?

A: To verify and confirm, you can use the following steps:

Check the blockchain explorer to see if the blocks have been successfully submitted and processed.
Verify that the blocks are correctly linked to the previous blocks.
Confirm that the network is functioning correctly.

Q: What are the best practices for submitting missed L2 blocks or previous preconfer?

A: The best practices for submitting missed L2 blocks or previous preconfer include:

Regularly checking for gaps between the L2 head in the taiko-client and the first block in your batch.
Submitting previous preconfer first.
Verifying and confirming that the blocks have been successfully submitted and processed by the network.

Q: Can I automate the process of submitting missed L2 blocks or previous preconfer?

A: Yes, you can automate the process of submitting missed L2 blocks or previous preconfer using tools and scripts. This can help ensure accuracy and efficiency.

Q: What are the consequences of not submitting missed L2 blocks or previous preconfer?

A: The consequences of not submitting missed L2 blocks or previous preconfer can include:

Inconsistencies and errors in the network.
Double spending.
Loss of trust in the network.

Q: How often should I submit missed L2 blocks or previous preconfer?

A: You should submit missed L2 blocks or previous preconfer as often as necessary to maintain the integrity and accuracy of the network. This may be daily, weekly, or monthly, depending on the specific requirements of your network.

Conclusion

Submitting missed L2 blocks or previous preconfer is a critical step in maintaining the integrity and accuracy of the blockchain network. By following the best practices and guidelines outlined in this article, you can ensure that your network remains intact and accurate, and that you prevent double spending and ensure consensus.
