Odysseas Lamtzidis builds the systems that keep Web3 from falling apart.
A blockchain security expert with roots in academic research and protocol engineering, Odysseas has spent the last decade pushing the boundaries of how decentralized systems can be made safer, stronger, and more transparent.
He began his journey at the University of Patras, publishing peer-reviewed research on decentralized IoT security and blockchain-integrated precision agriculture—work that earned recognition from IEEE GLOBECOM and MDPI. But it was in the industry where his work began to shape real-world protocols.
At Nomad, he contributed to the design of core infrastructure for cross-chain communication—experience that proved essential when the protocol suffered a $190 million exploit.
“Security isn’t about patching holes,” he says. “”It’s about rethinking how the system is built—before someone else finds the weakness.””
In 2024, he founded Phylax Systems, a venture-backed security startup focused on real-time exploit prevention. The team’s flagship product, the Credible Layer, has already raised $4.5 million in pre-seed funding from Figment Capital, Bankless Ventures, and Robot Ventures.
Beyond his technical work, Odysseas advises blockchain VCs and frequently judges major Web3 hackathons like ETHDenver and ETHBerlin. He’s been named to Forbes Greece 30 Under 30 and featured in outlets like CoinDesk, The Block, and even the U.S. Embassy in Greece.
“I’m not here to make headlines,” he says. “I’m here to build the security foundation this ecosystem actually needs.”
