In recent years, a large number of personal privacy data have been leaked .2021 year 10 month 4 On Tuesday night ,Facebook、Instagram and WhatsApp Massive downtime , It is said that more than 15 Billion Facebook User data is being sold on a popular hacker related forum , The data contains the user's name 、 E-mail 、 Phone number 、 Location 、 Gender and users ID.

In fact, this is not Facebook For the first time, such a serious event of user privacy information exposure ,2021 year 4 month ,Facebook Your server was attacked , Lead to 3 It was exposed within days 5.33 Personal data of 100 million users , It involves 106 Countries and regions , The leaked information includes the user's Facebook account name 、 Location 、 Birthday and email address , In great detail .

In this context , A decentralized account system different from the traditional account model （DID） Maybe it can bring us some new thinking and imagination space .

 01 
What is? DID？ How to integrate with blockchain ？

In the traditional Internet world , We are already familiar with things like mobile phones 、 Microblogging 、 Wechat and other Internet identities in the form of accounts , these The identities of different ecological segments are managed and saved by corresponding centralized Internet service providers , Therefore, it is impossible to avoid the corresponding hidden danger of centralization .

In addition to these service nodes, we have the right to close our accounts , And make us lose the identity of multiple sites at the same time , More serious is the problem of collective privacy disclosure —— The centralized architecture is destined to be an unavoidable event once its privacy disclosure occurs .

and DID（Decentralized Identifier）, That is, a decentralized identity system , be Use blockchain and other technologies to make digital identity truly owned and controlled by users , Like we put our ID cards 、 passport 、 Keep these paper documents in your home carefully , Only take it out when you need it , There is no longer any middleman who fully owns the user's identity and data , Can better avoid the above difficulties .

say concretely , stay DID In the framework of , Individuals can have a digital identity that contains all this information and is managed separately , Instead of multiple centralized providers managing multiple digital identities , At the same time, there is no need to trust a third party to keep it , Without the express consent of the owner , No individual or institution may use these identities for any purpose .

I understand it is Really put personal privacy 、 The right to data is returned to everyone's free control , No longer hold the privacy that should belong to users like the current Internet giants 、 data , Financing yourself 、 list 、 Carry out commercial activities such as killing and ripening , As contributors, users don't enjoy the rewards they deserve .

So in Web 3.0 Time , With the help of DID Users will have more control over personal identity and data , Although blockchain is not DID A must for Technology , But blockchain technology can help DID , Avoid many disputes , And can maintain the credibility of data at a lower cost .

In particular , Blockchain based DID The plan has 3 Some advantages ：

Personal data ownership

Based on blockchain, identity data is prevented from being controlled by a single centralized authority , The identity of each user is controlled by its owner , Individuals can manage their own identity , There is no need to rely on the application that provides the identity .

Complete privacy

Users no longer need to use a phone number 、 Register your account with your ID card and other information , The user's use of decentralized identity means that the user's privacy will no longer be stolen by the centralized platform and do evil through these data , Cause harassment such as the customer service of the trading platform we often encounter .

convenience

Users can access and participate in blockchain projects with only one decentralized identity , This lowers the threshold for users to enter the blockchain world , In addition, it also brings users a better experience . Just like we currently use MetaMask The wallet can log in 、 Enjoy almost all DeFi、NFT etc. DApp Application service , In the traditional Internet Ecology , We have a wechat account 、 Netease accounts and other accounts divided one by one , This is also Web3 The inevitable development trend of the times .

 02 
DID What blockchain scenarios can be enabled ？

in short ,DID Itself is committed to integrating existing 、 As much identity information as possible for each user , Create a digital identity that is not limited to any fragmented platform , Such a digital identity will eventually surpass Web2.0 Cloud identity on , Cross platform identity , Realize a comprehensive individual identity cognition system .

and DID Information aggregation can not only bring the above advantages , At the same time, it can also make the user's digital identity more rich and three-dimensional , It can even derive a one-stop solution to obtain different blockchain networks DID Data solutions , Aggregate the identity data generated by users in different blockchains .

Most directly , For our blockchain users at present , Assets on the personal chain 、 Transaction records 、 Behavioral data are also equivalent to a “ Sleeping gold mine ”, There is no mature credit system to mine and quantify the hidden value , Thus, the credit accumulated on the blockchain and digital assets is basically wasted .

however DID In the current blockchain world, it seems to face problems similar to the real world “ Slice and dice ” trouble ： Although from the capital volume 、 At the user data level , Ethereum is a well deserved leader , But Boca 、Solana And other blockchains can not be directly ignored , At present, the data retained between different chains is like an island .

So if DID It is no doubt unfair to only focus on Ethereum in the process of construction ： For example, except for some funds in ETH、BSC Wait on the public chain , Another part may be in Solana On the chain “ farming ”.

Then in this case , Only with ETH To judge the individual's credit in the chain based on the asset status and behavior data , It is undoubtedly biased . Especially under the background of the continuous expansion of the development volume of each family , Combine information from different perspectives on different blockchains , Often more comprehensive results can be obtained 、 More valuable information .

Therefore, based on DID Of DeFi、NFT etc. DApps It can provide different levels of services for different users . For example, an entity with a good debt service history can obtain loans from a lending platform with less collateral , Or new DeFi The project may prevent robots from using their imaginative new use cases such as airdrops for human users .

For example, referring to many evaluation dimensions of sesame credit sub system , Enjoy credit rights and interests according to the most direct considerations such as asset status and behavior data on the chain —— stay DeFi Mortgage borrowing , Using personal chain credit to obtain mortgage rate discount, etc , In this situation DID It's just a lot DeFi The basic support of products and services .

also DeFi The world's unsecured credit intermediation is just a typical small example , stay DID Under the blessing , The value of data on the chain of ordinary users is no longer sleeping , You can experience more based on identity and credit DeFi Product service .

 03 
DID Of “ New infrastructure ” attribute

Credit has always been a big business , In the modern financial system , The most important core driver is the credit factor , In essence, modern finance is also a variety of derivative games based on credit .

stay DeFi Under the background of gradual improvement , The next wave of explosion is destined to be in DID On the basis of . therefore If identity credit is implemented in the blockchain network , Can give birth to a large number of financial products , From this point of view ,DID In fact, it plays a key role “ New infrastructure ” role .

meanwhile , Traditional Internet giants have not stopped their own layout , since DID Since the birth of , World wide web consortium (W3C) He began DID The standard setting of , Microsoft at present 、IBM And so on DID Protocol method , And have launched their own solutions .

Microsoft

2018 year 2 month , Microsoft announced that it will DID As the strategic entry point of the company's blockchain , Same year 10 Published in 《 Decentralized identity 》 white paper .

And then 2019 year 5 month , Microsoft released ION (Identity Overlay Network, Identity overlay network ) The decentralised identity of (DID) An early preview of the web . People in the industry think , If Microsoft puts DID The function is preset into Microsoft's hardware products , It's likely to be like that Windows 95 The operating system is the same , Play a widespread role in popularization .

IBM

IBM Several projects related to distributed digital identity are also arranged , These include IBM And HyperLedger Co sponsored Indy,Hyperledger Indy Project Sovrin Is a pioneer in enterprise class solutions , For enterprises, it is necessary to immediately deploy open source technology-based services DID Have an advantage .

IBM And SecureKey And the blockchain authentication network being built by members of the Canadian digital identity ecosystem .Visa Also in the 2019 In the first quarter of IBM Jointly launch a blockchain based digital identity system to improve cross-border payment security .

Summary

On the whole , In addition to the layout of traditional Internet giants , At present, the blockchain industry is exploring DID There are more and more supporting solutions for decentralized identity , As Web3.0 An indispensable core component of the times ,DID To some extent, it is the key of the industry “ infrastructure ”.

From a decentralized identity framework , To data management applications , Then to the data exchange platform , Basically, a closed loop can be formed logically , So that users can completely have their own complete decentralized identity , Master your own data , Make effective use of and give full play to the value of data , Lay the foundation for more diversified application scenarios .

Perhaps in Web3.0 The times are getting closer to us ,DID Is beginning to build a new network system and innovative play methods based on personal identity , Let's continue to pay attention .
