Since the development of the Internet, the Web 2.0 era has produced a network society, and society is no longer limited to geographical boundaries, while Web 3.0 introduces the concept of decentralization, emphasizing individual data privacy and trusted interoperability. In this new era, decentralized identity (Decentralized Identifier or DID) came into being. DID allows users to have full control over their digital identities without authorization from a central authority. DID is generated based on the blockchain, and users can use it on different platforms and manage the association of multiple identities. This kind of digital identity of user sovereignty is in line with the concept of decentralization of Web3.
For the DID Protocol platform, DID allows users to use encrypted wallets as digital identities, and the authenticity of NFT can be verified to reduce fraud and false behaviors, so that the platform has real and credible user data. Of course, the operation of DID Protocol requires the data support of NFT, which brings more security, credibility and transparency to the confirmation, transaction and identity verification of digital assets:
-
Confirmation of title and source verification: creators can attach their Web3 identities to NFT, thus easily proving that the NFT was created by them, and buyers and others can confirm the source and authenticity of NFT by verifying DID, reducing false works risks of.
-
Transaction transparency: On the blockchain, it can ensure that the ownership transaction of NFT is transparent and traceable, which helps to eliminate potential disputes and provides the integrity of transaction history.
-
Enhanced authentication: In the NFT market, buyers and sellers can be authenticated through DID. Sellers can increase buyers' trust in transactions by displaying identity information associated with their DIDs, and buyers can use their DIDs to verify their identities, ensuring they are transacting with legitimate sellers.
-
Digital rights management: provide more flexible solutions for the management and control of digital assets. Creators can use their DIDs to manage their work and exercise fine-grained control over its access and usage.
-
Smart contract interaction: Smart contract interactions related to authentication, rights management, and digital asset ownership can be enabled. Provide more advanced functions for various application scenarios.
It is very difficult for the DID Protocol development team to obtain NFT data, which involves a certain amount of work and complexity. It is indeed a challenging task for the development team to obtain and process NFT data in the application. This process involves the intersection of multiple technical fields, including blockchain integration, data accuracy, privacy protection, and more. In order to overcome these difficulties, NFT data service providers can play a key role. Standardized data interfaces make it easier for development teams to integrate NFT data into their applications, eliminating the problem of adaptability to different data sources and formats.
With the professional and reliable API interface provided by NFTScan, developers can directly obtain comprehensive, complete, and real-time updated NFT data without having to deal with the complex capture of on-chain data by themselves, which significantly improves development efficiency and reduces maintenance costs, helping developers Focus more on application innovation, make full use of NFTScan's multi-chain NFT data to quickly build powerful applications and create a better user experience. Compared with self-developed on-chain data capture system, directly using NFTScan's rich multi-chain NFT data is undoubtedly the best choice.

Build related NFT requests
It is very simple and convenient to construct NFTScan-related NFT data requests. Developers only need to find the required interface in the API documentation, and check the interface address, request method, request parameters and other descriptions. Then choose a programming language according to your own needs, such as JavaScript, Python, Java, etc., use the HTTP request library of the language to send a constructed request to the interface address, and filter the necessary header information and parameters. The entire calling process is fast and convenient, and developers can implement it completely according to the documentation.
For example, we request NFT statistics for a wallet address:
“/v2/statistics/overview/{account_address}”，
The HTTP GET request accesses the API endpoint of NFTScan, using Python's requests library, the request can be constructed like this:
In the above code, we first define the base URL of the NFTScan API, and then specify the wallet address to query. By splicing the wallet address onto the base URL, we construct the full request URL. Next, we use the get method of the requests library to initiate an HTTP GET request, and process the returned data according to the response status code.
The above sample code is just to illustrate how to use Python's requests library to construct HTTP GET request to access NFTScan's API endpoint. In actual use, developers may also need to consider more details such as error handling, authentication, and parameter passing. When using the API, please consult the official documentation of NFTScan for accurate API endpoint and parameter information, and follow best practices to ensure data security and accuracy.
