EigenDA uses Dual Staking of ETH and EIGEN, where EIGEN stakers can be forked for data availability assurances. Rollups are also allowed to integrate their own token quorum so that DA commitments are validated by both the default EigenDA quorum and the custom rollup quorum.

While native rollup staked tokens and the unknown DeFi risk profile of EIGEN may introduce moderate initial risks, the strong quorum composition and the ability to soon slash intersubjective faults through the sovereign token establish a robust business model, where all quorums must be compromised in order for EigenDA to fail, which appears challenging to execute.

Being mindful in setting a biased staking balance in favor of ETH is strongly advised for added security, particularly at the early stage of an AVS.

EigenDA allows rollup nodes to interact directly with a majority of EigenDA nodes, alleviating centralization pressures by bypassing the need for a single leader to order the data. Existing solutions rely on a single leader to sequence blobs, introducing a potential censorship chokepoint.

Furthermore, rollups on EigenDA can now reserve a chunk of bandwidth (1MB/s, e.g), helping alleviate current data congestion issues, surge pricing, and fluctuating gas fees — throughput is greatly increased as a result.

BFT consensus imposes minimum thresholds of 1/3 and 2/3 validator agreement for liveness and safety guarantees, respectively.

EigenDA has introduced new low node requirements to promote decentralization and increased throughput. The minimum node requirement for validator participation is only 0.5MB/s (three orders of magnitude lower than current standards); the more stake delegated, the more node bandwidth becomes available.

At scale, TEE and DVT would potentially still be worth considering.
