L2BEAT introduces a risk framework designed to evaluate the security of data availability solutions

On May 27th, the open-source L2 data analytics website L2BEAT has introduced a risk framework designed to evaluate the security of data availability (DA) solutions. From an Ethereum perspective, the security assumptions of an external DA provider depend not only on the intrinsic characteristics of the DA solution itself, but also on how its security attributes map to the data proofs of the DA bridge published to Ethereum. The fraud detection mechanism category measures the effectiveness of a user's self-protection against a malicious majority of committee members, such as validators; proof security evaluates the ability of the DA bridge to validate data commitments without introducing additional trust assumptions. The exit window standard examines the scalability of the DA bridge, with a particular focus on the withdrawal mechanism and the time at which users are allowed to exit when upgrading.
