Worldcoin gained popularity years ago by scanning iris scans, and now another project aims to solve the problem of real-person verification with just a mobile phone. Moreover, the investment institution behind it is quite prestigious: Draper Associates, founded by Tim Draper, has previously invested in well-known companies such as Coinbase, Tesla, and SpaceX. The project they are leading this time is called @projectsolo, which completed a $1.2 million funding round in 2025 and focuses on real-person verification in the AI era. Now that AI agents are becoming increasingly prevalent, problems such as bulk account registration and bot-driven account manipulation are becoming more and more common. How many real people are actually online in the future? That's questionable. Solo aims to solve this problem by enabling real-person verification using a regular phone camera, while protecting privacy with technologies like zero-knowledge proofs. The project has also made some progress within the Solana ecosystem. Solana has previously retweeted Solo's post, and the project was selected for the fifth cohort of the Solana Incubator. Furthermore, its real-person verification function has been expanded to Discord and Telegram, helping the community identify bot accounts and reduce Sybil attacks. Currently, Solo has launched apps for both iOS and Android, requiring no special iris scanning equipment; it can be used with any regular phone. For those who like to invest in early-stage projects, I think it's worth keeping an eye on. While there's no confirmed airdrop news yet, there might be some surprises later!
