Switch Resolve Sequence Number To Use `/v1/accounts/ADDR/keys/KEY_INDEX` Endpoint

by ADMIN 82 views

Introduction

In the pursuit of enhancing the efficiency and speed of transaction processing, we are proposing a significant improvement to the sequence number resolution mechanism. The current approach involves querying the entire account, which can be detrimental to performance, especially for wallets with a large number of keys on their system accounts. In this article, we will explore the benefits of switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint for resolving sequence numbers.

The Problem with Current Approach

The current method of resolving sequence numbers involves querying the entire account, which can lead to significant latency issues. This is particularly problematic for wallets that have a large number of keys on their system accounts. For instance, a payer or proposer account may have a massive key count, resulting in an extremely costly preflight request. This can have a ripple effect on the overall performance of the system, leading to slower transaction processing times.

The Benefits of Switching to /v1/accounts/ADDR/keys/KEY_INDEX

By switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint, we can significantly improve the performance of sequence number resolution. This endpoint allows for a more targeted approach, where only the specific key index is queried, rather than the entire account. This reduction in data retrieval can lead to substantial latency savings, making the system more efficient and responsive.

Example Request

To illustrate the benefits of this approach, let's consider an example request:

GET https://rest-mainnet.onflow.org/v1/accounts/0x34ac358b9819f79d/keys/0

In this example, the request is querying the key at index 0 for the account 0x34ac358b9819f79d. This targeted approach allows for a more efficient data retrieval, reducing the latency associated with querying the entire account.

Implementation Details

To implement this change, we will need to modify the sequence number resolution mechanism to use the /v1/accounts/ADDR/keys/KEY_INDEX endpoint. This will involve updating the API to handle the new endpoint and modifying the underlying logic to query the specific key index rather than the entire account.

Benefits for Wallets

The benefits of this change are particularly significant for wallets that have a large number of keys on their system accounts. By reducing the latency associated with sequence number resolution, wallets can experience improved performance and faster transaction processing times. This can lead to a better user experience and increased adoption of the Flow blockchain.

Conclusion

In conclusion, switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint for resolving sequence numbers can have a significant impact on the performance of the system. By reducing the latency associated with querying the entire account, we can improve the efficiency and responsiveness of the system, leading to a better user experience and increased adoption of the Flow blockchain.

Future Work

As we continue to develop and improve the Flow blockchain, there are several areas where we can build upon this change. Some potential future work includes:

  • Optimizing API Endpoints: We can continue to optimize API endpoints to improve performance and reduce latency* Improving Wallet Performance: We can work with wallet developers to improve the performance of their applications and reduce the latency associated with sequence number resolution.
  • Enhancing User Experience: We can continue to enhance the user experience by improving the performance and responsiveness of the system.

Recommendations

Based on our analysis, we recommend switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint for resolving sequence numbers. This change has the potential to significantly improve the performance of the system, leading to a better user experience and increased adoption of the Flow blockchain.

Introduction

As we continue to develop and improve the Flow blockchain, we want to ensure that our community has a clear understanding of the changes we are making. In this article, we will address some of the most frequently asked questions about the switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint for resolving sequence numbers.

Q: What is the current approach to resolving sequence numbers?

A: The current approach involves querying the entire account, which can lead to significant latency issues, especially for wallets with a large number of keys on their system accounts.

Q: Why is the current approach problematic?

A: The current approach is problematic because it requires querying the entire account, which can result in an extremely costly preflight request. This can have a ripple effect on the overall performance of the system, leading to slower transaction processing times.

Q: What is the /v1/accounts/ADDR/keys/KEY_INDEX endpoint?

A: The /v1/accounts/ADDR/keys/KEY_INDEX endpoint is a new API endpoint that allows for a more targeted approach to resolving sequence numbers. Instead of querying the entire account, this endpoint allows for the querying of a specific key index.

Q: How does the /v1/accounts/ADDR/keys/KEY_INDEX endpoint improve performance?

A: The /v1/accounts/ADDR/keys/KEY_INDEX endpoint improves performance by reducing the latency associated with querying the entire account. By querying only the specific key index, this endpoint reduces the amount of data that needs to be retrieved, resulting in faster transaction processing times.

Q: What are the benefits of switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint?

A: The benefits of switching to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint include:

  • Reduced latency associated with sequence number resolution
  • Improved performance and responsiveness of the system
  • Better user experience for wallets with a large number of keys on their system accounts

Q: How will the switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint affect wallets?

A: The switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint will have a positive impact on wallets, particularly those with a large number of keys on their system accounts. By reducing the latency associated with sequence number resolution, wallets can experience improved performance and faster transaction processing times.

Q: What is the timeline for implementing the switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint?

A: The timeline for implementing the switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint is currently under development. We will provide updates on the implementation timeline as more information becomes available.

Q: How can I get involved in the development of the Flow blockchain?

A: We encourage anyone interested in contributing to the development of the Flow blockchain to join our community. You can find more information on how to get involved on our Flow GitHub and Flow Community pages.

Q: What are the next steps for the Flow blockchain?

A: The next steps for the Flow blockchain include:

  • Continuing to optimize API endpoints to improve performance and reduce latency
  • Improving wallet performance and reducing the latency associated with sequence number resolution
  • Enhancing the user experience by improving the performance and responsiveness of the system

Conclusion

In conclusion, the switch to the /v1/accounts/ADDR/keys/KEY_INDEX endpoint for resolving sequence numbers is a significant improvement to the Flow blockchain. By reducing the latency associated with querying the entire account, we can improve the performance and responsiveness of the system, leading to a better user experience and increased adoption of the Flow blockchain.
