What is a good way to authenticate your identity?

Original title: "V God praises the airdrop revolution: fascinating applications of blockchain identity verification, Worldcoin and four major challenges"
Original author: Zhang joy, BlockTempo


Ethereum founder Vitalik Buterin has recently interacted with netizens on the social platform X very frequently, especially expressing his views on the DeFi track. And yesterday (29), Vitalik once again took the "airdrop" that is well known to people in the currency circle as the topic, discussed the relationship between Airdrop and blockchain identity proof, and praised "airdrop as a fascinating example of identity authentication."


Airdrop is a fascinating example of identity authentication


Vitalik first stated in the tweet that airdrop is a fascinating example for zero-knowledge proof (ZK) and blockchain identity:


"Airdrop is a fascinating example of zero-knowledge proof, blockchain-based identity, credentials, and proof frameworks. The goals of airdrops are:


. Paper hands (diamond hands opposite) distributed to community members, not immediately sold;


. Reward contributions to the project;


. Pursue equality (but accept some differences);


. Fight against meaningless reward tasks.


These also happen to be the goals that ideal identity proofs want to achieve. Therefore, for anyone building an identity proof or credential framework, it is important to use token distribution as an initial use case to conduct Beta testing in a hostile environment. It makes sense to test and improve the project. "


Discount sales can also be seen as a way of distributing tokens


In addition, Vitalik added that airdrops are not the only meaningful form of token distribution. For project parties, they can also sell tokens at a discount:


"A key point is that giving away tokens for free is not the only meaningful way. You can also sell at a discount.


Depending on the level of contribution you have, you can buy a corresponding amount of large amounts at a discount, which helps to make the supply of tokens more decentralized and reward those contributors, while ensuring that there are real buyers involved."



Worldcoin still needs improvement


In response to Vitalik’s mention of airdrops and identity verification, some community members immediately thought of Worldcoin, a cryptocurrency project supported by OpenAI CEO Sam Altman. V God also responded positively:


“Worldcoin can handle the identity verification part, which is good, but I think it also needs to increase the authentication of community members. After all, no one actually wants to distribute tokens to other people. People hope that people who agree with the community hold these tokens.”


Last year, Vitalik also expressed doubts about the actual operation of Worldcoin, believing that the existing solutions still cannot prevent Orb Potential privacy breaches caused by hardware devices:


"Broader thinking around biometrics and proof-of-personhood protocols is a good direction, but risks include inevitable privacy breaches, further shrinking rights to browse the web anonymously, possible government coercion, and the practicality of maintaining security while maintaining decentralization."


In general, he listed four main risks:


· Privacy. Registration of iris scans could leak information.


· Scaling barriers. Unless there are enough devices that anyone in the world can easily obtain, the World ID will not be reliably accessible.


· Centralization. The Orb is a hardware device, and we cannot verify that it is constructed correctly and has no backdoors. There are also risks to the centralization of the Worldcoin Foundation.


· Security. A user's phone could be hacked and the user could be forced to scan their iris while showing a public key belonging to someone else.


What does Vitalik think is a good way to authenticate your identity?


Last week, Vitalik mentioned an authentication method, namely cross-social identity, in a 10,000-word article titled "Plurality philosophy in an incredibly oversized nutshell".


The book says:


"Many of the simplest ways to establish identity also destroy it, especially on the Internet. Passwords are often used to establish identity, but unless identity verification is done carefully, it can be leaked more widely.


Using a person's entire set of behaviors and interactions to confirm identity, such as determining community membership and a person's trustworthiness, is a comprehensive, retrievable, and balanced approach to privacy and security."


In this regard, Vitalik also expressed his full agreement. He believes that the core problem is that any single-factor identification technology is too fragile, so we should use multi-factor technology:


"Many airdrop attempts in the Ethereum ecosystem use a combination of multiple factors to determine the credibility and membership of an account, and give it a universal basic income (UBI) or voting rights proportional to that score."
