Dinis
PhD researcher in Information Management at NOVA IMS, Universidade Nova de Lisboa, and Ethereum Foundation PhD Fellow. At the Nova Blockchain Lab I lead the peer to peer energy market task of COMMUNITAS, a Horizon Europe project, and I built and run the Nova Cidade L3, the Arbitrum Orbit chain where its households trade energy every hour. My research is on blockchain settlement for energy communities and the privacy of the people in them, with a side line on LLMs for smart contract security. I studied computer science at Instituto Superior Técnico (MSc thesis on Solidity smart contract security) and worked as a Solidity developer and auditor before the PhD.
Session
Forty-eight households in three European energy communities trade electricity every hour on an Arbitrum Orbit L3, each from its own wallet, so every home leaves a public and linkable record of its demand on chain. I use the anonymity set literature to measure how much that crowd hides and how far Semaphore membership proofs and stealth addresses, the subject of my EF PhD Fellowship, can restore it.
