Original title: "In addition to Worldcoin, you must know the identity authentication system"
Original source: Biteye
As the number of airdrops grows, project owners are becoming increasingly cautious about issuing airdrops, such as Worldcoin, a popular project in the past two days.
Although first-tier exchanges such as OKX and Binance have announced that they will list their token $WLD, as a project that intends to issue airdrops to all mankind, Worldcoin faces a heavier task of preventing witches, which has led to the controversial iris authentication.
In addition, the Linea testnet activity that just ended not long ago also introduced an identity authentication link to target Sybil attacks. Users who complete the identity authentication can get an additional 2,500 points.
The current attitude of the project party towards witches is already evident. Account authentication has become a compulsory course for everyone who interacts with the project. Today's article will introduce you to several popular identity authentication and anti-witch projects.
01. World ID
introduce
Worldcoin is a crypto project founded in 2020 by Aam Altman, the founder of OpenAI. It aims to use blockchain technology to establish an open source protocol for global financial equity and inclusion.
With the popularity of ChatGPT, this 2020 project has gradually become well-known. But in fact, in June of the same year, Worldcoin received $25 million in financing with a valuation of $1 billion. The investment lineup was luxurious, including Digital Currency Group, Coinbase Ventures, a16z, Multicoin Capital, as well as LinkedIn founder Reid Hoffman and FTX founder Sam Bankman-Fried.
At the end of March 2021, Worldcoin received another $100 million in financing at a valuation of $3 billion.
Currently in many countries in the world, there are still many people without legal identity. What Worldcoin wants to do is to provide these people with a unique digital identity.
The goal is to create a digital economy in which anyone can participate and ultimately benefit from this decentralized collective ownership.
To achieve this goal, the first thing is to ensure that enough people use its tokens, so token airdrops are an essential operation.
As mentioned at the beginning of the article, if Worldcoin wants to carry out such a large-scale airdrop, the anti-witch task it faces is bound to be more arduous, so they directly carried out a wave of hardcore authentication, directly confirming the real identity through the user's iris information.
Worldcoin consists of three parts: tokens, World ID (DID), and World APP (wallet). World ID is used to verify the unique identity of the user, prevent witch attacks, and receive $WLD airdrops through World APP.
There are many methods for real-person verification, such as face, fingerprint, gene, etc. Worldcoin uses iris verification, focusing on its uniqueness and anti-fraud capabilities. In short, iris is more difficult to forge.
The promotion and operation of World ID is also relatively simple. Worldcoin launched an iris detector Orb, and then they recruited local agents in various countries. After assessment and training, they distributed Orb to these agents to complete the iris collection task.
The more irises agents collect, the more rewards they get. In addition, every time they collect a user's iris, they will be given some small gifts and token rewards, so the overall effect of its ground promotion is still good.
Because its identity authentication is too hardcore, it cannot be completed without Orb. In addition, collecting user biometric information is too sensitive, and the laws of many countries prohibit institutions from privately collecting user biometric information and taking this information out of the country.
Therefore, the biggest obstacle to its iris authentication at present is the number of Orbs and compliance restrictions of sovereign countries.
Worldcoin has planned to increase the number of Orbs to 1,500 this summer and fall, and will also launch World ID in more countries and regions, such as the United States, Mexico, Hong Kong, Japan, Singapore, etc.

Since the World ID authentication requires the Orb to collect irises, if your country or region is not supported by Wordcoin, you will not be able to obtain a World ID. Therefore, we will only talk about the operable part and the basic principles of authentication.
First, users need to download their wallet World APP, which is now available on major app stores.
After the wallet is installed, you will be asked to choose whether to create a new wallet or import an existing wallet. When creating a new wallet, you will also be asked to verify your phone number, but you can choose to skip it and verify it later.
If you want to verify immediately here, you need to turn off the VPN. After the verification, 25 $WLD tokens will be issued to you.
The basic principle of verification is that when you create a new wallet, you will get a key pair, including a private key and a public key. The user provides the public key to the iris detector Orb for detection, and Orb will use an algorithm to calculate an IrisHash unique identifier based on the collected iris image.
When there is no IrisHash in the database, it means that the user is registering for the first time. Only after passing such verification can the user successfully register a new World ID.
02. Gitcoin passport
introduce
Gitcoin Passport is probably the most well-known identity verification system. Gitcoin is an open source donation project based on Ethereum. Its main purpose is to help some open source projects raise funds and build a communication bridge between projects and users.
Gitcoin was founded in 2017 by American engineer and entrepreneur Kevin Owocki, and subsequently received $11.3 million in funding from Paradigm in April 2021, and another $500,000 raised from the Ethereum Foundation in November of the same year.
As a donation platform, Gitcoin has raised early funds for many excellent projects, and these projects have also issued airdrops to donating users, such as GTC, ENS, BrightID, etc.
Since donations can easily get project airdrops, a large number of users donated for airdrops, and thus Gitcoin Passport came into being.
Gitcoin Passport is a Web3 authentication aggregator designed to prevent Sybil attacks. It collects verifiable credentials to prove user identity and credibility while protecting user privacy.
In Gitcoin's own quadratic donation mechanism, there is a concept of matching donations. When users make donations, Gitcoin's funding pool will also match additional donations to the project based on the number of donors to the project.
Only those with a Gitcoin Passport score of 21.76 or above are eligible for matching donations.
As Gitcoin’s influence grows, its Passport is slowly being accepted by other projects, such as the new public chain Linea mentioned above.
In the future, some projects will most likely require Gitcoin Passport scores as a threshold. As users, we also need to complete the corresponding authentication tasks.

https://passport.gitcoin.co
The overall operation of Gitcoin passport is relatively simple. You can open their official website to clearly see all the tasks.
After each task is completed, a corresponding score will be given, such as binding a Google account, Facebook account, or Discord account.
Based on the completion of these tasks, Gitcoin gives an overall score of the user's authenticity. The higher the score, the more credible your wallet address is.
If other projects adopt Gitcoin Passport's score, then when you interact with that project, the higher the score, the lower the probability of being considered a witch.
For the specific scores for each task and strategies on how to get more than 20 points at the lowest cost, please refer to the mind map and strategy previously released by Biteye.

03. Named
introduce
Nomis is an on-chain reputation project that suddenly became popular a few days ago. It was launched by the Web3 credential data network Galxe and aims to use the transparency of blockchain to establish an open Web3 on-chain data reputation system.
In airdrop activities, Sybil users often make profits in various ways, which usually causes great trouble to project owners and community members.
While the blockchain’s inherent transparency allows for the ability to see these Sybil users moving the same amount of tokens between multiple wallets, this information is useless without the right tools.
Nomis is one such tool that uses a custom wallet scoring model to assess the airdrop eligibility of an address. The score is based on more than 30 parameters, taking into account different types of wallet activity.
Through this model, project owners can customize parameters and weights to calculate user scores. Once a user's score is below a certain level, they can be clearly marked as a witch.
Nomis has always believed that even if the owner of the wallet is not a witch, using tools like Nomis can greatly reduce the workload of manual review.
Likewise, while it's not possible to change the mind of a Witch user, it's at least possible to nullify their actions, which is what Nomis does.
The reason why this project became popular is related to the popular second-layer public chain zkSync. Just when everyone was interacting with zkSync, the official zkSync suddenly retweeted Nomis's tweet, causing panic among the people. Many people began to worry that zkSync would also start to vigorously crack down on Sybil accounts.
Nomis officially released a related article, stating that it is the first identity protocol deployed on zkSync, which is of great significance to them.
But instead of worrying about the project party starting to catch witches, it is better to prepare in advance and improve the score. This is a wiser choice.

Open the official website and you can see the multi-chain comprehensive score of our bound wallet on the left. Users with more than 40 points can mint the Score SBT on the right. This SBT costs money. In other words, 40 points may be a passing score.
If we want to improve the score here, we can take a look at the components of the score, which can be seen in the Stats below the score.
Based on the description on the right, we can basically summarize the following operations to improve the score:
Add wallet funds
Increased trading volume
Increase transaction frequency
Increase the number of NFTs in your wallet
Increase the total value of NFT

In addition to some operations of the project itself, you can also go to Mint the official article published on Mirror when zkSync was launched as mentioned above, which is a commemorative moment. The handling fee of Optimism is very cheap, about 0.1U, and only 28 people are Minting it at present.
04. Epee score
introduce
Degenscore is a decentralized identity system based on on-chain behavior. Unlike Nomis mentioned above, it does not support multiple chains. The scores of Degenscore are all composed of behaviors on the Ethereum mainnet.
Users with a score of over 700 can mint a Degenscore Beacon’s SBT, but reaching a score of 700 is not easy.
Although it is quite difficult, there are still many benefits once you pass the Degenscore certification.
Many projects will cooperate with Degenscore to provide users with whitelist benefits, etc. The most well-known example is the Lens whitelist. At its peak, one Lens was worth about 270U.
Projects using Degenscore:

Wallet Project XDEFI Wallet
https://twitter.com/xdefi_wallet
etc…
Degenscore has many cooperative projects, which you can check on the official website. Most of the projects listed in Cafe use Degenscore.
operate
https://degenscore.com
When you open the Degenscore official website, you will see the Cafe interface, which includes three parts: Opportunities, Abilities, and Jobs, telling users directly what the benefits of holding Beacon are.
Opportunities: Beacon holders can experience the internal testing functions of these cooperative projects in advance
Abilities: Beacon holders have special rights in cooperative projects
Jobs: Beacon holders can get priority employment opportunities in recommended projects and companies
Click Beacon in the menu bar above and select Overview to see the application interface. The minting process is simple, the only requirement is that the address must be more than 700 points.
It’s easy to improve your score. Just find Leadrboard under Beacon in the top menu bar and interact with the projects that the top 100 high-scoring users have interacted with.
Since it is operated on the main network, users need to prepare more ETH as GAS.
05. Earthquake
introduce
Sismo is an on-chain reputation project based on zero-knowledge proof. It is said to be a startup project of former Aave employees and completed a US$10 million financing in December 2021.
The investment lineup is quite strong, including Framework Ventures, Delphi Digital, Fabric Ventures, Global Coin Research, Seed Club Ventures, etc.
One of its main features is that users can prove that they own an asset without disclosing their wallet address.
This is very attractive to some users who want to show their strength but are afraid of leaking their privacy. For example, Vitalik, the founder of Ethereum, once mentioned in his blog that he is very optimistic about the identity ecosystem and gave examples to illustrate it. Sismo is a project he specifically mentioned.
(Vitalik blog, https://vitalik.eth.limo/general/2022/12/05/excited.html)
So how does Sismo solve this problem? Many users in the crypto world do not have only one wallet. For example, one wallet has 100 ETH and another wallet has 100 UNI. When I participate in the corresponding meetings, I need to show proof of assets twice.
There are two problems here. One is that I need to disclose my two addresses, and my privacy cannot be guaranteed. The other is that I need to show proof of assets twice, which is cumbersome.
In the official introduction of Sismo, the concept of single sign-on is mentioned. It means that users only need to log in once, and can pass verification directly in other places without logging in. For example, once you log in to your Google account, Gmail, Youtube, Google Translate, Google Docs, etc. will automatically log in, without the user having to enter the account password multiple times to log in repeatedly.
Sismo's badge plays this role. Users only need to be verified once to generate a badge, and you can send this badge to another new address that has no assets.
In this way, even if the new address does not have this asset, with this badge, you can prove your on-chain identity. And because the badges are all on one address, users do not need to use multiple wallets for multiple verifications.
Projects using sismo:

Multi-chain DeFi aggregator rhinofi

operate
Sismo's current operation is to obtain badges. There are two main types of badges, one is the official badge, and the other is the badge issued by a third party, such as the badge that users who donate G15 can receive.
https://app.sismo.io/
When you open the link above, the first thing you see is the G15 badge. If you can't find it, you can search for keywords in the search box on the left.
(Author's note: the URL app.sismo.io may become invalid in the future. You can use apps.sismo.io instead.)
Go to the badge details page and claim it directly. If your wallet does not meet the requirements, you will be asked to change a wallet.
Currently, many badges are time-limited, and there are relatively few badges that can be obtained. After the Sismo update, it also provides the function of creating badges.
Open the website below and click "Create a Data Group" to create your own badge. Although this badge you create may not have much weight, just treat it as an experience project.

06. Conclusion
The projects mentioned above are just some of the more popular and noteworthy projects in the field of identity verification. There are still many other similar projects:
Binance Account Bound (BAB): used for identity authentication of Binance wallet accounts. Just complete KYC. The threshold for Binance-related projects
Galxe Passport: A passport launched by Galxe. You only need to complete KYC. The threshold for some projects on Galxe
Debank: A multi-chain DeFi wallet that recently launched a badge feature and has its own WEB3 ID, but it costs $96
The above five projects are summarized as follows:
1. World ID is currently facing the biggest controversy. Although from the perspective of anti-witch, its iris authentication can filter out most witches, even some real users are filtered out because the verification is too difficult.
However, the collection of user biometric information is a very sensitive operation. Although Worldcoin has stated that it will not save users' iris images and will delete these images once the algorithm is optimized, we do not know when the optimization will be completed and whether leakage will occur during the collection process by local agents.
At the same time, due to the number of Orbs, the efficiency of this off-chain verification is far less than that of the on-chain. Therefore, whether World ID is a reliable, effective and secure identity authentication tool remains to be verified.
2. The most widely used one should be Gitcoin Passport. It uses a lot of tasks to verify the identity of users, both on-chain and off-chain. The evaluation of user identity is relatively complete and reliable.
In the future, many project developers will use its verification as a tool to filter out witches. Users who want to win airdrops should pay more attention to and improve their scores on Gitcoin Passport.
3. Nomis is the easiest and most cost-effective platform. Users do not need to complete various tasks. They only need to do more operations on the chain, save more money, and buy more NFTs to improve their overall scores.
Moreover, it is a multi-chain comprehensive score. You can operate on the second-layer chain, which not only saves money but also makes the user evaluation more diversified.
4. Degenscore is probably the most difficult and expensive to operate. Not only are there many tasks, but they also need to be operated on the main network. Users may need to prepare a lot of handling fees to support the interaction, which is too costly.
Although the amount of funds can determine the authenticity of the address to a certain extent, for a project, the premise for screening out real users is authenticity, not just the amount of funds.
Using Degenscore as a tool to judge witches will seriously distort the results. In my opinion, Degenscore is more like a rich club, or as its name suggests, a Degen (veteran, heavy user) club, so ordinary users don’t need to be too obsessed with the high or low scores.
5. The last one is Sismo. Its advantages are that it uses zero-knowledge proof and focuses on privacy protection. However, Sismo is still in its early stages, with few cooperative projects and changing technical routes, so there are not many things that users can experience. For now, you can experience the badge collection or badge creation function, and keep an eye on its new developments.
