3. EigenDA
EigenDA is a data availability service built as an Actively Validated Service (AVS) in the EigenLayer’s Ethereum restaking ecosystem. Data Availability Approach: An encoded data blob is sent to an operator by a disperser, and cryptographic commitments and operator attestations are used to prove that the data has been accepted for storage.
Performance. Built for high throughput and lower data-publishing costs than directly storing equivalent payloads on Ethereum, due to its distributed architecture. Capacity is determined by configuration and service conditions.
Security Model: EigenDA is built on restaked ETH, operator duties, cryptographic verification, and economic penalties for specified misbehavior. It is not public data availability sampling, because its guaranties are different. The users are advised to carefully evaluate the assumptions of the operator and the retrieval.
