EigenDA is a secure, high throughput, and decentralized data availability (DA) service built on top of Ethereum using the EigenLayer restaking primitive. Developed by EigenLabs, EigenDA will be 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 security and throughput designed to horizontally scale with the amount of restake and operators opted into servicing the protocol.
