Senior Protocol Researcher
Eigenlabs
ABOUT EIGEN LABS Eigen Labs is more than just a leading name in the blockchain space. We’re the driving force behind EigenLayer, a game-changing solution that revolutionizes crypto-economic security. Imagine a world where blockchain projects break free from the shackles of the scaling trilemma and capital limitations.  In today's blockchain ecosystem, each service is typically secured by its own tokenized trust-network. With EigenLayer, services can build upon the established security of the Ethereum trust network, unlocking untold scalability while maintaining security and decentralization. Enter EigenDA: Provisioning data availability is one of the key components for scaling blockchains, and specifically Layer2 rollups. EigenDA is a secure, high throughput, and decentralized data availability (DA) service built on top of Ethereum using the EigenLayer restaking primitive. Developed by Eigen Labs, EigenDA is the first actively validated service (AVS) to launch on EigenLayer. Restakers will be able to delegate stake to node operators performing validation tasks for EigenDA in exchange for service payments, and rollups will be able to post data to EigenDA in order to access lower transaction costs, higher transaction throughput, and secure composability across the EigenLayer ecosystem. With EigenLayer, building blockchain infrastructure modules (AVSs) in a permissionless manner is no longer a hypothetical—it's our reality. Now, we invite you to be part of this exciting journey. ABOUT THE ROLE  This role represents an opportunity to drive the future of our protocol security and design. This role combines cutting-edge cryptographic research with practical implementation, requiring someone who can think both theoretically and pragmatically.
