Giovanni Mazzeo
I am a Web3 entrepreneur, senior software engineer, and Associate Professor of Computer Security, working at the intersection of blockchain protocols, confidential computing, and trusted execution environments.
I am currently CIO at Trillion.xyz, a company building a decentralized exchange with trust and verification properties while, at the same time, ensuring high-performance execution. My role at Trillion is to lead and conduct applied research that directly supports the design of cutting-edge security solutions. The core research is focused in combining zero-knowledge proofs with trusted execution environments, thus enabling hybrid proof architectures that balance efficiency and verifiability in layer-2 systems.
Previously, at Credora (formerly X-Margin), I led the design and development of a decentralized application enabling community-based DeFi asset risk scoring. The platform allowed distributed contributors to provide and validate risk signals, which were aggregated through cryptographically verifiable attestations to produce transparent, on-chain risk metrics for DeFi protocols. This work supported Credora's growth phase and fundraising by delivering a novel, decentralized approach to credit and risk assessment in DeFi.
I hold a PhD in Information Technology, with research focused on trustworthy cloud provisioning and data-in-use protection using emerging CPU security extensions. Alongside my entrepreneurial activities, I am an Associate Professor and Researcher of Computer Security at the University of Naples Parthenope, where I conduct research on confidential computing and blockchain. I have authored over 60 peer-reviewed publications and have served as principal investigator or technical lead in multiple EU-funded Horizon projects.
My work focuses on turning cutting-edge security research into real-world, production-grade Web3 infrastructure.
