👶 Analogous explanation: DID is like your Web3 'ID card'

  • In real life, everyone has an ID card, passport, phone number, etc., which are identifiers that prove 'who you are'.

  • But in the online world, we use accounts from centralized platforms, such as WeChat ID, Douyin ID, email accounts. These identities belong to the platform, not to you.

  • One of the goals of Web3 is to allow you to 'turn your online identity into an asset that you own', and that is DID.

🛠 DID Technology Framework

  • A DID looks like this:

    makefilecopyeditdid:example:123456789abcdefghi

  • Each DID is generated by you (not registered), can be stored on a blockchain, and linked to your wallet, public key, social information, etc.

  • You can also authorize other platforms to read some of your data without exposing all your privacy.

🔐 What can DID do?

🧠 What possibilities does DID have in Web3?

  • Game character: DID is your 'character card' in blockchain games, outfitting experience, assets, levels.

  • DAO member identity: Use DID to represent your voting rights and participation records.

  • Career resume: In the future, it may be like 'on-chain LinkedIn', showcasing your real project contributions, experiences, etc.

❗ Current challenges

  • Compatibility: There is a lack of unified standards among projects, leading to a fragmented ecosystem;

  • Popularity: For new users, DID is too abstract and needs a more user-friendly entry point;

  • Privacy and Regulation: How to handle identity-related data on an open chain is still being explored.

✅ Summary

  • DID is the identity system of Web3, aiming to give users true ownership of their online identity;

  • It will appear in various scenarios in the future, such as social media, gaming, DAOs, and on-chain resumes;

  • Although still in its early stages, it may become one of the foundational technologies of Web3, worthy of attention and study.
