Innovators use .xyz domains to develop infrastructure for digital identity, finance, and emerging technology. ZK platform Succinct.xyz introduces tools for faster and more scalable blockchain applications. ZK protocol Cysic.xyz aims to decentralize proof generation and verification for the blockchain ecosystem. Programmable datachain Irys.xyz introduces a model for onchain data interaction. In this week’s #BlockchainThursday, we’ll introduce you to a privacy-focused identity protocol building ZK verification tools for proving humanity online: Self.xyz.
Self.xyz is the online home of Self Protocol, an identity infrastructure designed to verify real users on the internet without exposing their personal information. According to Self documentation, the protocol uses zero-knowledge (ZK) proofs to confirm attributes such as age or nationality based on electronic passports while preserving privacy. It supports Sybil resistance, selective disclosure, and verification flows that can check if a user exists. In November 2025, Self raised $9M to advance its technology and introduced a points program for verified users.1
Self Protocol fits within a growing group of web3 projects working on privacy-preserving identity solutions. According to Self Labs, onchain applications face challenges such as bot activity, duplicate participation, and compliance requirements. The project aims to help developers confirm that individuals interacting with an application are unique humans while allowing them to reveal only selected attributes. Its documentation lists use cases including airdrop protection, sanctioned entity checking, and wallet recovery. Self Labs acquired OpenPassport, a project focused on verifying humans online, to extend its approach to human verification and scale its infrastructure across decentralized applications. This integration paired OpenPassport’s identity tooling with Self’s proof-based verification system.2
According to his LinkedIn profile, CEO and co-founder Eric Nakagawa previously served as Executive Director at the Celo Foundation, a nonprofit organization that supports the Celo blockchain ecosystem and aims to expand mobile access to digital finance. He earlier led developer relations there. Eric also co-founded I Can Has Cheezburger?, a humor blog that later spawned a book, and SimpleHoney, a travel-oriented consumer app. The “I Can Has Cheezburger?” book appeared on the New York Times Best Sellers list in January 2009, 3and SimpleHoney was acquired in 2013.4
Self.xyz functions as the primary online destination for information about Self Protocol and its ecosystem. The website hosts documentation for builders, product details, and updates on integrations, including Self Pass, Self Connect, and Self Points. The short and memorable Self.xyz domain offers a direct naming format that aligns with other blockchain and privacy-focused projects using .xyz. This can support findability for individuals searching for the project by name while placing Self within a broader ecosystem of digital-native technology platforms. You can learn more by following the platform on X/Twitter and Linkedin @self-xyz and by visiting Self.xyz.
