All things can be proven: the assets and identities under the chain chain

Author: Starzq, web3brand

In this issue, we will introduce a project about “proof”.If you also see an interesting project that conforms to the above definition in Build or, please recommend it to us.

1. How to “prove” I have Li Zhi’s album?

Last month, I saw my friend NASA’s water gift box, and the conditions were also very interesting. Through screenshots [Netease Cloud Music-Purchasing List], “Prove” has Li Zhi (Brother B) album.

As a senior B fan, how can such welfare be missed? Speed ​​screenshots, now I am eating this article while eating lotus fog.

Lotus fog is indeed delicious, but to be honest, the cost of falsifying a screenshot is very low or even zero. I am also worried that NASA will be wool by “non -target users”, so I start thinking about the problem in the title:

How to “prove” you have Li Zhi’s album?

The simplest is to bring physical albums and meet offline.This method is true but the cost is too high, and in the digital era, there are very few people who have physical albums themselves.

Li Zhi has released several digital albums on Netease Cloud Music, which can theoretically allow Netease Cloud Music to provide an API inquiry “I own Li Zhi’s album.”

But this is obviously unrealistic

1. API needs to be developed by Netease Cloud Music. I must first find a way to find the corresponding person in charge;

2. Suppose I really found the person in charge of Netease Cloud Music. Development API is also a small cost, usually not in the OKR of the department;

3. Suppose I am willing to invest in this cost, this API is finally developed, but it is also necessary to solve the problem of user privacy, and the issues of laws and regulations.

It is difficult to imagine how many people/brands can cross these three obstacles to prove what they have.

2. Web2: You need to overcome three pain points in order to prove what you have

In essence, there is no OWN in Web2, and we rarely have (OWN) our own data and assets. The data belongs to the centralized institution and does not belong to you.

In the recent example, in order to apply for the EU Schengen Sign in December, in addition to personal information, I also need to prepare the followingProof materialThe

1. On -the -job certificate: The company with the official seal of the official seal and the copy of the business license of the unit

2. Asset certificate: The salary card or debit (savings) card of the transaction records in the nearly 6 months of the transaction record in the past 6 months is the original part of the bank;Copy of motor vehicle registration certificates

3. Travel certificate: air tickets, hotels, daily itinerary lists

4. Relative proof: original part of the notarization of children in Chinese and English

To complete the above “proof”, you need to overcome the three pain points below

1. You need a centralized agency to prove the data you produce

1. Need a company to prove that I work

2. Need a bank to prove my asset

3. Need the housing management office to prove my property

4. Need the vehicle management office to prove my car production

5. Need to book a ticket website to prove my air tickets and hotels

6. It even needs a separate notarized institution [Hague notarization] to prove “my daughter is my daughter”

7. “Prove your data” is often not low in cost

1. I need to write an email to apply for the company [On -the -job Certificate] and explain why you apply for an application

2. I need to go to the bank to open the asset certificate

3. In order to prove that “my daughter is my daughter”, you must make an appointment time, and then spend 600 RMB to buy a notary!(EU visa is really outrageous)

4. Different institutions are scattered in different centralized institutions/servers, and it is very troublesome to use together

1. I want to copy all these materials together, count it, and almost 100 pages (requiring a copy of the passport to copy, including a blank page).It took more than an hour to print the information of yourself and his family.EssenceEssence

After experiencing the above, I should never go to the EU Schengen to sign it in the past 5 years.

It is hard to imagine that we live in such a magical era. On the one hand, we are filled with “The Graduation is changing!”The XX AI model is here!”,” Only 1 year away from AGI “… This kind of news headlines; on the other hand, we rarely have (OWN )’s own data and assets,” it is difficult to prove what you own “.

3. Opportunities for web3: All things can be proved

The core of the web3 is OWN, and everyone can build and own their own chain assets, which will be proved by the chain records.

However, the limitation currently faces is that most of our asset certificates still have a chain, which leads to a lack of identity on the chain and limited application scenarios:

• Financial application: lack of real estate proof, stock certificate, bank deposit certificate

• Workplace application: lack of academic qualifications, work proof

• Social application: Lack of interest proof (how to “prove” I have Li Zhi’s album?), Relationship certificate (how to prove that one sister and Sun have followed me)

• Nympho

Some projects in the industry have also discovered the pain points of this series of web2 and the opportunity point of Web3. Build contains the proof protocol on the chain and under the chain. One of them is the SIGN Protocol we want to introduce below.

3.1 Definition and history of ATTESTATION

Let’s first look back at the definition and history of the proves (Attestation) to help us better understand how the Sign Protocol changes the proof of this matter.

Attestation and Verification have the meaning of “proof”, both refer to the confirmation process of a certain information, transaction or process, but there are key differences between them

• Attestation refers to a statement or an authoritative entity to declare or prove the authenticity or something of something.In the process, it involves a clear statement that confirms that the content of the review is correct, authentic or compliant.For example, a registered accountant audited and issued a audit report on the company’s financial statements, which is considered a proof of its financial status.

• Verification is more focused on determining the accuracy of a certain information through inspection or survey.It usually involves a series of testing, analysis or evaluation processes to confirm whether the information or the system meets specific standards or expectations.For example, the code verification process in software development to ensure that the software runs normally without errors.

In short, the proof of (attestation) is usually executed by an external authorized agency/witnesses (Attestor) to prove the authenticity of certain information; verification is usually a more technical process. Check whether the information or the system is correct or the system.Effectively and comply with norms or expectations.

Based on this definition, who the witness is and what the form of witness determines the final efficiency and effect of the proof.



It can be seen that the form of prove (Attestation) is becoming more and more electronic, and it is indeed more convenient; but for thousands of years, the role of the witness (ATTESTOR) is a centralized agency, which has led to what we encountered in the beginning.Pain point: You have to find a centralized agency to generate proofs passively. The cost is high efficiency and it is difficult to use.

However, it can be seen from the definition and history of Attestation that it is not solving a technical and algorithm problem, but to solve a social consensus problem.

When it comes to “consensus”, there is an opportunity for blockchain to allow these witnessed and declared events to be defined in accordance with certain standards, and then through the blockchain to become the data on the chain that users can OWN, it is improving efficiency, which improves efficiency.At the same time, greater potential is released through the characteristics of blockchain and smart contracts.

3.2 How to achieve “all things can be proved”

According to official introductionSIGN Protocol is an Omni-Chain Attestation Protocol. Users can prove their data without licenses and build a chain proof.

The first core concept in which is ZKATTESTATIONS. Compared to Web2 through centralized agencies to ensure the authenticity and integrity of the information, ZKATTESTATIONS uses zero knowledge to ensure integrity.Through TLSNOTARY and other technologies, users can directly prove information from web pages and private messages without having to go through any centralized entity.The protocol uses ZK to verify that the data of the website is indeed derived from the server of the information provider and has not been changed.

(Note: TLSNOTARY is an open source project supported by the Ethereum Foundation for recording and verifying the TLS connection. The verification of a certain information is indeed issued by a company’s server to create the authenticity of encryption on any data on the network.Proof; Zkattestations is a zero -knowledge proof technology that allows users to prove that they have certain attributes or qualifications without leaking any personal identity information.

Source: tlsnotary.org

For example, when users log in to China Merchants Bank, they can expand data from the China Merchants Bank server through the browser.The expansion program will then generate an encryption certificate to verify more than 200,000 information such as users.

This can produce a more powerful vampire attack, as we see in Sushiswap and Uniswap or Blur and Opensea.With ZKATTESTANS, web3 can conquer Web2 through simple incentive measures.

Suppose that Binance or OKX wants to airdrop to US stock users, boring apes (Bayc) or Pudgy Penguins wants to air investment to Web2 tide players. All users need to interact with ZKATTESTATION to prove their US stocksTransaction volume, fashion costume consumption.

Through the user’s self -evidence, users do not have to disclose any personal information, nor do they need Binance, OKX, boring apes, and fat penguins to find the corresponding web2 company to need data to complete all the above matters.Users migrate to Web3 and move towards Mass Adoption.

For example, “My China Merchants Bank’s balance exceeds 20W”, “I spend more than 5W in Farfetch last year”, which is called SCHEMA, which is the second core concept in Sign Protocol.Each Attestation Schema is composed of Header and Body, allowing witnesses to verify whether the user can pass the corresponding certification.

(Friends who are not interested in technical details can skip the following two pictures directly)

Header: Including the key context information, witnesses can quickly infer the information related to proof.Header contains the following elements:



Body: Includes the complete context of certification and metadata content.Here, witnesses can provide extensive data and comprehensive information for confirming the given claims or assertions.Body includes the following elements:



Through the combination of Header and Body, SCHEMA provides a structured framework, which precisely defines the nature of the proof, ensuring that they are not only confirmed, but also related necessary information, which has become the foundation of the proof system on this chain.

At the same time, SCHEMA also has a combination of available. Take the EU Schengen as an example. If there are already SCHEMA 1 -SCHEMA4 support the on -the -job certificate, asset certificate, travel certificate, and relative certificate, it is easySchema5, all the proofs at one time, think about it.

Unlike the WEB2’s witnesses (ATTESTOR) are basically centralized agencies, everyone can create SIGN Protocol’s schema. It also means that it can build decentralized chain proof based on SIGN Protocol.””.

3.3 Build new assets, unlock new scenes, capture new value

The user’s self -evidence supported by ZKATTESTATIONS, the decentralized chain supported by SCHEMA proves that the SIGN Protocol can more effectively build the assets and identities of the upper part of the user chain, and unlock the new scenarios that the web2s cannot achieve, capture the caught, captureNew value.

New scenes are mainly divided into two categories

1. Airdings based on web2 assets and identities

1. Through SIGN Protocol, the user’s assets transfer to the chain from WEB2’s Walled Garden garden (Walled Garden) to the chain. Whether it is the web3 project to get web2 users, or to compete with each other between the web2 projects, it will become extremely easy.Open a new paradigm;

2. Brand and user’s Open Loyalty

3. Complete decentralized social platform: interest identity, workplace identity, social relationship …

1. Web2 social platforms can’t get the other party’s data (Facebook cannot get LinkedIn data, Douyin can’t get WeChat data), users lack a complete social experience and need to be maintained on multiple closed platforms;

2. Web3 social platforms cannot get the rich social data of Web2, which causes most projects to only be “chain” and no “social”; there is no “social”;

3. The current social platform is “incomplete” for users

4. Once the user uses SIGN Protocol to put his interest status (I bought Li Zhi’s album), the workplace identity (once worked in ABC and other companies), and social relationships (by the attentionHave the opportunity to build a complete decentralized social platform.In the new generation of social platforms, there are no more closed data for the competition, but whose user experience and rights are better.

New value

Once the user can OWN’s own assets, they can continue to capture new value:

1. Make your existing chain/offline assets and identity, receive the airdrop of the project party, and turn your data into value.

1. At the same time, this will also greatly stimulate the paradigm operation of Open Loyalty.When we wrote Open Loyalty before, assuming that the brand party would issue its own NFT membership card, but if the brand is not positive, the member data is still in the closed database, it is difficult to truly realize the Open Loyalty.

2. But based on Sign Protocol, I am a member of Lego. I do n’t need to get the consent of Lego. Based on the corresponding SCHEMA, you can generate the chain of this member card without permission to get my value.

3. This will also force the brand to change the paradigm of user operations and transfer more rights to users.

4. What’s more interesting is that because the positive flywheel of “user data → value capture” will inspire users to generate more meaningful data and enrich the entire ecology

1. Ten years ago, FourSquare was all the rage. Users to sign in to generate geographical records by signing in, and the corresponding medal of Collect, but because of lack of incentives, it is difficult to motivate users to continue to use;

2. If the user’s sign -in record can be proven on the chain, which is used by other project parties, and at the same time, the user benefits, which will make users more willing to UGC.As a first -generation UGC product manager, I look forward to seeing some new UGC mechanisms.

3.4 Summary and outlook

1. Decentralization proof of VS tradition proves that the witness (ATTESTOR) is composed of Zkattestation and decentralized SCHEMA. The user is active, the cost is lower, has a combined avitilliveness, and can prove “everything”, bringing more value capture space for space capture spaceItems

2. Decentralization proof can unlock 2 new scenarios, airdrops based on Web2 assets and identities (user growth and operation will open a new paradigm), complete decentralized social platform;

3. Not only can help users build assets and identities under the chain of the chain **, ** and can inspire users to generate new data, and continuously capture value based on their own data.



The predecessor of Sign Protocol is the document signature applied to ETHSIGN. Based on blockchain and smart contracts, the cost of signature signature signatures has been reduced by more than 10 times.ETHSIGN has obtained the investment of Sequoia and Balaji. After 5 rounds of iteration, it has become the number one contract signing application in Web3. It has built an interface in applications such as Telegram and Line to provide more than 300,000 users.Wait for government identity system integration to achieve higher levels of compliance.

In essence, EthSign is an application for “proof”.The team saw the potential of the “proof” field. Based on the back end of ETHSIGN, the SIGN Protocol was constructed to expand the content of the proof from the document generated by users to everything.

The team launched a fun thing based on SIGN Protocol at the beginning of this month.New Year’s first signature(SIGN) “ATTESTATATATATATAON), participants can limited time Mint Lucky Dragon NFT, get additional benefits in the future community plan.

This is the team’s first Pilot based on Sign Protocol. This event generates 316,259 chains in 24 hours, which shows that everyone is willing to record some interesting “proofs” on the chain.

My first signature of my New Year is “The next 10 years, save 10 big cakes for my daughter”:)



Next, I hope that more people and project parties can contribute a variety of Schema and make fun things based on SIGN Protocol.I also hope that when I apply for an XX visa next time, I can directly complete it through the chain (which state will be the first to support, or a network state?)
