    Advancing global standards for decentralized data infrastructure — certified by IEEE and verified through BMM.
    Data Sovereignty
    Verifiable ownership and privacy-first control. Empower users, enterprises, and institutions to own, share, and monetize data with on-chain proofs.
    Compliance by Design
    Built on internationally recognized standards. Aligned with IEEE P3320.02, GDPR, and verified through the Blockchain Maturity Model (BMM) for enterprise and government readiness.
    Programmable Economy
    Turn data into secure digital assets. Enable tokenization, permissioning, licensing, and governed data exchange across industries.
    AI Connectivity
    Real-time, trusted data for AI systems. Provide verifiable, high-throughput data pipelines for enterprise AI, public infrastructure, and research applications.
    Bringing real performance to decentralized data

    What our partners are saying

    Javier Casado
    CESS gives developers the freedom to build applications where end users control their data.
    “Decentralized Identity is not possible without CESS. Only via their innovative server network that puts users in control of their data are we able to build Anon ID as a frictionless authentication Wallet. CESS is at the forefront of functional decentralized and secure technological infrastructure and I would not build anywhere else. The freedom to build our customized solution is one of the man reasons why we say yes to CESS. ”

    Mark Wang
    CESS offers the perfect complete Ecosystem for our Decentralized Streaming Platform
    Our ultimate goal for TellyWelly is to return data control and sovereignty rights back to the users. We searched extensively for an ecosystem that includes a fast, inexpensive, reliable blockchain along with decentralized storage, and decentralized CDN. We found all of this with CESS. Plus their Proxy Re-encryption Technology (PReT) is uniquely offered only by CESS.
