“Blockchain API Design: Core Concepts and Best Practices” – W3C working group, editors: M. Speck, I. Zu, 2018

In 2018, the W3C Blockchain API Working Group published a report entitled “Blockchain API Design: Core Concepts and Best Practices.” This talk covers the basic concepts and best practices for designing APIs for blockchain applications. Blockchain technology is quickly becoming popular, with many companies and organizations realizing its potential to transform their operations. APIs are a key component of integrating blockchain into existing and new applications. Well-designed APIs can facilitate the development and deployment of blockchain-based applications, while poorly designed APIs can become a barrier to adoption of the technology. The talk covers key API design principles, including the importance of security, scalability, and interoperability. It also provides guidance on best practices in areas such as endpoint design, API versioning, and documentation. The working group focuses on how features of blockchain technology, such as distribution and consensus, should influence API design, and offers practical recommendations for creating APIs that are both powerful and easy to use. In addition to design recommendations, the report also discusses implementation issues such as selecting the appropriate communication protocol and best security practices. It also addresses issues related to blockchain infrastructures and their impact on API design, and provides guidelines for adapting APIs to different infrastructures. Overall, “Blockchain API Design: Core Concepts and Best Practices” is a comprehensive guide to designing high-quality APIs for blockchain-based applications. It contains valuable guidance and best practices developed by leading domain experts to help developers and organizations build a reliable and interoperable infrastructure for their blockchain applications. The report is available as a free download on the W3C website, and the working group welcomes input and feedback from the community to help continue to develop best practices in blockchain API design.

Key concepts and best practices:

Blockchain technologies continue to transform many industries, offering unprecedented levels of transparency, security and decentralization. With the development of this area, there is a need to standardize interfaces for interacting with blockchains, which is important for application developers. In 2018, a W3C working group edited by M. Speck and Y. Zu released guidelines for blockchain API design, describing core concepts and best practices.

Basic Concepts

Decentralization

One of the key benefits of blockchain is decentralization. This means that the data is distributed over a network consisting of many participants, which makes the system more resistant to attacks and errors.

Immutability

Data recorded in the blockchain cannot be changed without changing all subsequent blocks and without the consent of the majority of network participants. This ensures a high level of confidence in the recorded information.

Transparency

Blockchain allows all network participants to view all transactions, which ensures a high level of transparency and trust between participants.

Consensus

To confirm transactions and add new blocks to the chain, it is necessary to achieve consensus between network participants, which guarantees the consistency and relevance of the data in the blockchain.

Best Practices for Blockchain API Design

Modularity and flexibility

The API should be designed to easily adapt to changes in blockchain technology and support various blockchain platforms.

Safety

Key focus should be on API security, including authentication, authorization, data encryption, and protection against various types of attacks.

Performance

You need to ensure high API performance to process requests quickly and efficiently, especially under high load conditions.

Idempotency

To ensure API reliability, operations must be idempotent, meaning repeated requests must produce the same result as the original request.

Compatibility and updates

The API must be designed to be backward compatible so that updates and changes do not break existing applications.

Conclusion

Developing a blockchain API is a complex task, requiring consideration of many aspects, from security and performance to flexibility and modularity.
