I just read Buterin’s article on biometric authentication to take a look at the personality certification highlighted in the article. There are two main things to prove in personality proof: 1. The user is a human being, not a robot. 2. The uniqueness of your identity. According to V God’s summary, we divide personality certification into three categories: personality certification based on social graphs, personality certification based on biological information collected by ordinary hardware, and personality certification based on biological information collected by special hardware. Simply speaking, based on the social graph, it is to ask people who have been authenticated to guarantee whether they are human beings. If they are human beings, they will be rewarded, and if they are not, they will be punished. Personality proof based on ordinary hardware to collect biometric information, such as faces, fingerprints, etc. Faces may change over time, and this type of information is easy to be stolen. Fingerprint information may be stolen in just one minute. . This is the method used by WorldCoin to prove personality based on biometric information collected by special hardware. Adopting this method will make the collection of biological information troublesome, machines will be concentrated in the hands of certain suppliers, and the idea of decentralization will not be implemented accordingly.

According to Vitalik's summary, we divide personality proof into three categories: personality proof based on social graph, personality proof based on biometric information collected by ordinary hardware, and personality proof based on biometric information collected by special hardware.
In simple terms, based on social graphs, it means that people who have been authenticated can guarantee whether they are human. If they are human, they will be rewarded, and if they are not, they will be punished. Based on the personality proof of biometric information collected by ordinary hardware, such as face and fingerprint, the face may change over time, and this type of information is easy to be stolen. Fingerprint information may be stolen in an instant. WorldCoin adopts this method of personality proof based on biometric information collected by special hardware. This method will make the collection of biometric information troublesome, and the machines will be concentrated in the hands of certain suppliers, and the idea of ​​decentralization cannot be implemented accordingly.
Vitalik also summarized the characteristics of these three proof mechanisms.
WorldCoin processes your iris through a specific machine learning model to verify and map it into a specific hash value, and binds it to the public key of your wallet.
V God also talked about the application prospects and functions of personality proof in the article. WorldCoin is a new attempt, let us wait and see how it develops.
