Self, a zero-knowledge (ZK) identity protocol focused on privacy-first digital verification, has announced a strategic collaboration with Google Cloud to drive the adoption of its privacy-preserving AI infrastructure and Web3 tools among verified human users. This partnership aligns with the growing demand for decentralized identity systems that allow users to prove personal characteristics—such as age or authenticity—without compromising sensitive data.
Utilizing zk-SNARK cryptography, Self enables users to confirm attributes while withholding the underlying personal details. The system is designed so that not even the developers of the protocol can access user data. This architecture ensures that personal information is neither stored externally nor exposed, effectively eliminating the risk of data leaks or unauthorized access.
A Global-Scale Identity Network
The reach of the Self protocol spans more than 8 million users and includes support for over a billion biometric passport holders across 129 nations. It also accommodates tens of millions of biometric ID holders in 27 European Union countries, as well as regions including Turkey, Ukraine, Vietnam, Ghana, and Saudi Arabia. Notably, Self is currently the only fully audited ZK-based identity protocol by zkSecurity that is operational across both iOS and Google Play platforms. It achieves this without relying on specialized biometric hardware, enhancing its accessibility and real-world applicability.
The protocol facilitates both offchain and onchain attestations, with the latter taking place on the Celo blockchain. Google Cloud, which has been running a validator on Celo since 2018, has also supported broader ecosystem growth, especially for sustainability-focused projects.
Integration With Google Cloud’s Web3 and AI Tools
As part of the partnership, Google Cloud plans to integrate Self’s zero-knowledge proof (ZKP) technology into several key offerings. One area of focus is the Web3 Portal, where the collaboration will explore linking Self’s protocol with emerging AI-powered search tools. Additionally, Self’s proof-of-humanity ZKPs will be embedded into Google Cloud’s Testnet Faucet to enhance Sybil resistance, an essential feature for preventing fraudulent identities within decentralized networks.
A pioneering Mainnet Faucet is also in development. This tool will use exclusion proofs from Self’s integration with the OFAC sanctions list to conduct sanctions screening—making it one of the first instances of real-time compliance tools integrated with blockchain identity verification.
Expanding Commitments to Privacy and Compliance
This partnership builds on previous collaborations between the two companies. Earlier this year, Self was chosen to provide age verification for Google Wallets in the United Kingdom. More recently, it was involved in privacy-first age assurance compliance efforts across the European Union.

Google Cloud leadership has emphasized that the rise of artificial intelligence within the Web3 space is lowering entry barriers for developers. Executives see the integration of ZKP-based identity technology with Google Cloud’s Web3 tools as timely and valuable, especially in supporting real users rather than just abstract network actors.
Meanwhile, Self’s co-founders expressed pride in the protocol’s rapid advancement, noting that its technology and accessibility have already distinguished it from competitors. They acknowledged that Google’s choice to implement Self’s SDK for identity solutions further validates its role in shaping the future of privacy-conscious Web3 and AI development.
Bridging Trust and Innovation in Web3
At its core, this partnership reflects a broader industry movement toward secure, decentralized identity systems that can scale globally. By combining cryptographic privacy assurances with Google Cloud’s cloud infrastructure and developer tools, Self aims to redefine how digital identity and compliance can function within the decentralized internet.
With strong foundations in both cryptography and global regulatory alignment, the Self-Google Cloud collaboration marks a significant step toward making private, verifiable digital identity a standard feature of Web3 ecosystems.
