Steffen Kux is Co-Founder and Co-CEO of corpus.core, where he works on trustless Ethereum infrastructure, stateless verification, and privacy-preserving client architectures. He has more than 25 years of experience in software architecture, product development, and blockchain systems. Before corpus.core, he contributed to Ethereum client-side verification work including minimal verification clients and Web3 infrastructure. At corpus.core, Steffen leads the strategy around Colibri, a stateless Ethereum client designed to verify blockchain data locally without syncing state or trusting centralized RPC providers. Colibri targets wallets, dApps, mobile apps, browser environments, IoT devices, and AI agents. The project focuses on execution proofs, consensus proofs, local transaction simulation, multi-chain verification, and Pragmatic Adaptive Privacy. Steffen regularly speaks about trustless infrastructure, RPC risk, stateless clients, and the need to make verification practical for real-world Ethereum applications.
