Human Identity Verification Solutions in the Web3 Space
One of the critical challenges of Web3 is the need for secure and reliable identity verification. This is because the decentralized nature of Web3 makes it difficult to rely on traditional identity verification methods, such as government-issued ID cards. Several blockchain projects are working on developing human identity verification solutions. These projects use various techniques, including blockchain, social media, biometrics, and traditional documents. We will review these projects in the following.
Traditional vs. Web3 Authentication Solutions
In traditional web2 systems, users typically rely on centralized authorities like governments, technology platforms, and financial institutions to validate identity credentials. However, these legacy models have limitations when it comes to user privacy, data security, and self-sovereignty. The decentralized nature of web3 presents an opportunity to develop identity protocols where users fully control their own credentials and data sharing. A handful of blockchain-based identity projects are aiming to deliver this vision.
Gitcoin Passport
Gitcoin Passport is one of the predominant projects in this field. Stamps are the activities and credentials users can use to receive a higher passport score. In fact, there are a myriad number of ways to prove the legitimacy of the account, including social media accounts such as Twitter, and Discord, Github and Google accounts, On-chain metrics such as number of NFTs, BrightID account, ENS domains, Snapshot Votes, as well as identity verification by ID card stamp.
The sum of all the stamps point forms the passport score, and a higher number means more on-chain and off-chain activities. Many projects in the early stages are now using this scoring system to ensure that the participants in their campaigns are real humans and not bots. The projects might require different numbers of scores based on the purpose of their campaigns.
Guild Pin
Guild Pin is another human verification platform by Gitcoin, a famous web3 platform for its granting program. It is becoming increasingly popular among well-known projects in the market. In this platform, any project can define a soul bond NFT with a few requirements (might be different for each project). Then, the user who wants this badge pays a small amount of cryptocurrency for the minting process to receive it in their wallet.
Projects can filter out users who have this badge on their wallet in order to disturb any potential rewards to the early adaptors or any other purpose.
Galxe Passport
Galxe is a pivotal project in the campaign and credential management in the Web3 space which has introduced a special service called Galxe Passport for human verification purposes. This service uses traditional authentication documents such as ID cards, passports, and driving licenses to provide a special badge to verified users. This platform claims that this data would remain encrypted and user has the fu control over it. Projects who want to ensure the legitimacy of users can use this service and ask their users to provide this passport.
Conclusion
Together, these projects represent a paradigm shift in establishing trust and reputation in digital environments. Rather than siloed profiles across fragmented platforms, web3 identity systems allow seamless and user-controlled identity portability. As web3 adoption accelerates, robust decentralized identity protocols will be crucial for realizing the promises of an open yet trusted ecosystem, and they will also make it easier for businesses to operate in the Web3 space.
