On the evening of October 4th, Facebook, Instagram, and WhatsApp experienced massive outages, rumored to exceed1.5 billion FacebookThe user's data is being sold on a popular hacker-related forum, and the data includes the user's name, email, phone number, location, gender, and user ID.
In fact, this is not the first time that Facebook and others have exposed such serious user privacy information. In April this year, Facebook’s servers were attacked, resulting in the exposure of 533 million users’ personal data within 3 days, involving 106 Countries and regions, the leaked information includes the user's Facebook account name, location, birthday, and email address, which is extremely detailed.

What are DIDs? How to combine with blockchain?
In the traditional Internet world, we are already familiar with Internet identities that exist in the form of accounts, such as mobile phones, Weibo, and WeChat.The identities of different ecological segments are managed and preserved by corresponding centralized Internet service providers.Therefore, the corresponding hidden danger of centralization cannot be avoided.
In addition to these service nodes having the right to close our accounts and make us lose the identity of multiple sites at the same time, what is more serious is the problem of collective privacy leakage-the centralized architecture is doomed that its privacy leakage is almost inevitable once it occurs Big event.
And DID (Decentralized Identifier), that is, a decentralized identity system, isUsing blockchain and other technologies to make digital identities truly owned and controlled by users themselves,Just like we keep paper documents such as ID cards, passports, and household registration books carefully in our own homes, and only take them out when needed, there is no longer any middleman who fully owns the user's identity and data, which can better avoid the above. dilemma.
Specifically, in the framework of DID, instead of having multiple digital identities managed by multiple centralized providers without trusting a third party to keep them, an individual can have one digital identity that contains all this information and manages it individually, No person or institution may use these identities for any purpose without the express consent of the owner.
i understand it isReally return personal privacy and data rights to everyone's free control,It is no longer like the current Internet giants that hold the privacy and data that should belong to users, and conduct financing, listing, and other commercial activities by themselves, but users, as contributors, do not enjoy the rewards they deserve.
Therefore, in the era of Web 3.0, with the help of DID users will have more control over personal identities and data. Although blockchain is not a must for DID technology, blockchain technology can help DID and avoid many disputes. And can maintain the credibility of the data at a lower cost.
Personal Data Ownership
Personal Data Ownership
Based on the 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 identities independently without relying on the application that provides the identity.
complete privacy
Users no longer need to register accounts through phone numbers, ID cards and other information. Using decentralized identities means that users' privacy will no longer be stolen by centralized platforms and use these data to do evil, resulting in situations like we often encounter. Harassment such as trading platform customer service.

What blockchain scenarios can DID empower?
In short, DID itself is committed to integrating the existing identity information of each user as much as possible, creating a digital identity that is not limited to any split platform, and such a digital identity will eventually surpass Web2.0. The cloud identity, cross-platform identity, realizes a comprehensive individual identity recognition system.
The aggregation of DID information can not only bring the above advantages, but also make the user's digital identity richer and more three-dimensional, and even derive a one-stop solution to obtain DID data from different blockchain networks.Aggregate identity data generated by users across different blockchains.
Most directly, for our current blockchain users,The assets, transaction records, and behavior data on the personal chain are also equivalent to a "sleeping gold mine", and there is no mature credit system to mine and quantify the hidden value in it, so that everyone in the blockchain The credit accumulated on digital assets is basically wasted.
However, in the current blockchain world, DID seems to be facing a "segmentation" dilemma similar to the real world: Although Ethereum is the well-deserved leader in terms of capital volume and user data, Polkadot and Solana , Terra and other blockchains cannot be ignored directly, and the data retained between different chains is like isolated islands.
So it is undoubtedly unfair to only focus on Ethereum during the construction of DID:For example, in addition to part of the funds being carried out on public chains such as ETH and BSC, another part may be "farmed" on Solana and Terra chains.
In this case, it is undoubtedly biased to judge an individual's credit on the chain only based on the asset status and behavior data on ETH. Especially in the context of the current expansion of the development volume of each company,More comprehensive and valuable information can often be obtained by combining information from different perspectives on different blockchains.
Therefore, DID-based DeFi, NFT and other DApps can provide different levels of services for different users. For example, entities with a good debt repayment history can obtain loans from lending platforms with less collateral, or new DeFi projects may prevent bots from taking advantage of their airdrops for human users, and other imaginative new use cases.
For example, refer to the many evaluation dimensions of the Sesame Credit sub-system, enjoy credit rights and interests based on the most direct consideration factors such as asset status and behavior data on the chain-in DeFi mortgage lending, use personal credit on the chain to obtain mortgage rate discounts, etc. In this scenario, DID is the basic support for many DeFi products and services.

DID's "New Infrastructure" attribute
Credit has always been big business, and in the modern financial system,The most important core driver is the credit element, and modern finance is essentially a variety of derivative games built on credit.
Under the background that the volume of DeFi has exceeded 110 billion US dollars, the next new wave of explosion is destined to be based on DID. soIf identity credit is realized in the blockchain network, a large number of financial products can be spawned. From this perspective, DID actually plays a key "new infrastructure" role in it.
Microsoft
Microsoft
In February 2018, Microsoft announced DID as the entry point of the company's blockchain strategy. In October of the same year, it published the "Decentralized Identity" white paper.
Then in May 2019, Microsoft released an early preview of the decentralized identity (DID) network of ION (Identity Overlay Network). People in the industry believe that if Microsoft presets the DID function into Microsoft's hardware products, it is likely to play a role in widespread popularization like the Windows 95 operating system back then.
IBM
IBM has also deployed a number of projects related to distributed digital identities, including Indy jointly initiated by IBM and HyperLedger. Hyperledger Indy's project Sovrin is a pioneer in enterprise-level solutions, and it has advantages for enterprises that need to immediately deploy DID based on open source technology.

summary
In general, in addition to the layout of traditional Internet giants, there are more and more supporting solutions for exploring DID decentralized identities in the blockchain industry. As an indispensable core component in the Web3.0 era, DID is in the To some extent, it is equivalent to the key "infrastructure" of the industry.
From the decentralized identity framework, to the data management application, and then to the data exchange platform, a closed loop can be formed logically, so that users can completely own their own complete decentralized identity, master their own data, and effectively use and play The value of data lays the foundation for more diversified application scenarios.
Perhaps under the background that the Web3.0 era is getting closer and closer to us, DID is beginning to build a new network system and innovative gameplay based on personal identity, let us continue to pay attention.
