Speakers
Nicolas is a co-founder of Ledger (https://www.ledger.com) and researcher at ZKnox (https://www.zknox.com) - interested in making hardware security open, understandable and affordable to all, currently exploring the frontier between TEEs and ZKPs and how to make AI more decentralized with crypto.
Pascal, a former Forex trader and DeFi power user since 2019, earns a living from his crypto portfolio. A renowned speaker, consultant, and teacher at Alyra, he co-authored France’s first certified DeFi course. He co-founded Jarvis Network, a stablecoin protocol enabling on-chain FX.
Krum, or as people know him "pashov" has done, led and been part of over 100 smart contract security audits. This has resulted in billions of dollars of user funds protected and secured. His team has audited protocols like 1inch, Ethena, LayerZero and more. His mission is simple - prevent as many hacks as possible, before the vulnerabilities even reach production environment.
Ivan has been building tokenomics and governance systems with Aragon since 2021, helping DAOs create and accrue value for tokenholoders. Previously he has helped DAOs deploy capital onchain with karpatkey and led OTC lending & prop trading at Nexo before DeFi was cool. Ivan is always up to talk about incentive alignment and value capture/accrual models in crypto.
