DID’s Inspirational Moment: Taking Digitization to the End

On July 19, DID (Decentralized Identifier) ​​has been launched as a W3C standard. I asked a bunch of DID related questions on July 20th:

Collection of questions about Decentralized Identifiers (DIDs)

As a result, half a month later, I still can’t answer my question. After reading all the results on the first few pages of Google about DID, and the related videos on YouTube, my anger kept growing. I’m turning to the world for help right now, on Twitter, etc.:

We know that URLs like http://abc.com can be entered into the browser’s address bar. Email addresses such as tom@abc.com can be entered in the recipient column of the email client. Even if it is a complex Ethereum address like 0x9eF….B1ba3, I know that it can be entered into the recipient column of the wallet transfer. Who can tell me:

1) In August 2022, is there even one place in the whole world that can display my DID address?

2) Is there even one place on the entire internet where I can enter a DID address like  did:web:abc.com  or  did:example:123  ?

3) Is there any app that allows me to use DID?

As I expected, no one could give me the answer. I’m a little crazy. Is this the status quo of DID that has been brewing for so many years? It seems a little bad breath. Logically, shouldn’t it be applied first? Two years before the official standard of HTTP/1.0 came out, Netscape, which used the native HTTP protocol, was already on the market.

But then immediately @w3tester classmate rescued me and recommended the app he made: https://credential.zkid.app. For the first time, I stumbled through the first DID experience in my life.

This has also been verified once again. Concepts always make people dizzy, and applications make people understand in seconds. The moments when these applications make people understand an obscure concept in seconds are what I call “daigo moments” (DAO example, NFT example, telephone counter example)

See your own DID address

Visit: https://credential.zkid.app 

After some simple mnemonic records or something similar to the normal wallet setup process, you can generate an ID, just like an Ethereum wallet, or a Bitcoin wallet. In the upper right corner of the interface, I saw a string of strings like this for the first time:



How to use this DID specifically can be discussed in detail in the next article. (In a word, DID seems to be a public key DNS)

get a certification

Inside a label of Credential Type, it is empty. @w3tester kindly gave me a CType: 0x7c98af5a580071e36baddebeee8000236095531819660dad994b9efb04f95a10 . I imported in, and the following organization appeared:


This one, called  DAO-Member-1  , seems to be an agency that can issue something.

Put the mouse on it, there is a “Create Claim” button. After clicking, the following interface will appear:


This form seems to be a bit similar to the forms filled in by many government departments. I filled in the information for myself, such as  Name: Jianshuo, Rank: 10, Role: Player , and clicked “Submit”.

After that, on the “Credential” page, I saw the following information:


The status of my newly submitted claim is  Attesting . Just wait for verification status.

After a while, @w3tester approved my statement from the system, and one of my statements as  Name: Jianshuo, Rank: 10, Role: Player  became Attested.

what happened? my guess

This process has ended like this, and there is no way to continue. But I have a vague understanding of the role and process of DID.

Dao-Member-1  may be another authoritative organization, it may be a university, it may be the Public Security Bureau, it may be any government agency, or any other organization, or your friend.

You go there and pick up a form, fill it out, and return the form to the agency for stamping.

This form might say when you graduated from this university, or your ID card, or your age, or just that I skated really well. Then the other agency will stamp you a seal with their DID identity (this is a mechanism called  Verifiable Credential , VC), and then you can take out an ID card, a driver’s license, etc. This table of numbers. This is what the future of forms such as ID cards will look like. Even if the agency’s website is gone, or even if the agency itself is gone, the table of numbers is still available.

That is to say, any place that involves stamping or signing in the future will have the opportunity to have a relationship with the verification of DID. After all, everything in the world that can be digitized is digitized, but we are still too backward in relying on our own little hands and wooden stamps.

I hope this process can help you understand a little bit. (Why only a little understanding? Because I only understand a little)
