Lightning rounds featuring three short talks: Kohaku, Gas Killer, and Threshold Homomorphic Private Voting, covering privacy, cryptography, and decentralized coordination.
Kassandra.eth is a core developer and protocol architect known for her leading work in on-chain liquidity management. She was the founder and Chief Technology Officer (CTO) of Arrakis Finance, a prominent decentralized finance (DeFi) protocol specializing in automated, concentrated liquidity management, and was previously known for her contributions to the Gelato Network.
She currently works at the Ethereum Foundation, where she contributes to Kohaku, and was selected as one of 15 members of the Foundation's Silviculture Society, an advisory group of blockchain experts tasked with helping the EF uphold Ethereum's core values of open-source development, privacy, security, and censorship resistance.
Kassandra is also a co-founder of Bread Cooperative, a worker-led collective building blockchain-based financial tools designed around solidarity and cooperative governance rather than purely extractive, investor-driven models.
Software Developer and Computer Scientist from the United States, currently based in London. He has been working professionally in the Ethereum ecosystem since 2018 with a focus on smart contracts. He is currently building Gas Killer, a verifiable off-chain compute service that uses EigenLayer to reduce gas costs for complex EVM transactions. He is a contributor for Bread Cooperative.
Luis Bezzenberger is a researcher and developer working at the intersection of applied cryptography, Ethereum infrastructure, and decentralized governance. At brainbot, he contributes to Shutter Network, focusing on threshold encryption, encrypted voting, MEV protection, and privacy-preserving applications for Web3.
His work includes Snapshot Shielded Voting, one of the largest encrypted voting systems used in DAO governance, as well as ongoing efforts to bring verifiable encrypted voting into real-world institutional settings. Together with Universität der Bundeswehr München and the City of Munich, he is currently working on a municipal voting prototype for a staff council election that combines client-side encryption, threshold homomorphic encryption, zero-knowledge proofs, and Ethereum-based public verifiability.
Luis has presented his work at conferences and events including EthCC, EDCON Osaka, Protocol Berg, DappCon, ETHWarsaw, StarkWare Sessions, and the Ethereum Cypherpunk Congress. His talks often explore how cryptographic infrastructure can move beyond theory and DAO governance into practical systems for coordination, privacy, and democratic participation.
