EigenDA

EigenDA is a scalable data availability layer built specifically for Ethereum rollups, leveraging EigenLayer's infrastructure to provide secure, cost-efficient, and decentralized storage for rollup transactions. It enables L2s to offload transaction data to a scalable, off-chain system while maintaining Ethereum's security guarantees.

EigenDA’s primary advantage is its hyper-scalability, currently supporting 15 MB/s of write throughput, with plans to scale up to 100 MB/s and beyond. This scalability is achieved by distributing the workload among a network of operators who are registered and staked in EigenLayer. These operators store transaction data as "blobs" until the rollup computes and finalizes the state on the bridge. By eliminating the need for independent consensus for data availability, EigenDA uses Ethereum's on-chain coordination while keeping the bulk of the data stored off-chain. The system relies on operators to verify and store these data blobs, with slashing penalties for misbehavior, making it economically secure.

EigenDA’s design prioritizes cost-efficiency, with users paying cents per MB of data, and decentralization, as the layer is operated by hundreds of operators, ensuring high participation and resilience.

By using EigenDA, Ethereum rollups can scale their transaction throughput without sacrificing security or decentralization. This approach is a significant evolution in Ethereum's L2 ecosystem, solving key scalability challenges for data availability in rollups while preserving Ethereum’s trust model.
