L2BEAT introduces risk framework to assess security of data availability solutions
On May 27th, open-source L2 data analysis website L2BEAT introduced a risk framework aimed at evaluating the security of data availability (DA) solutions. From the perspective of Ethereum, the security assumptions of external DA providers depend not only on the intrinsic characteristics of the DA solution itself, but also on how its security attributes are mapped to the data proofs of the DA bridge published on Ethereum. Fraud detection mechanism measures the effectiveness of users' self-protection when facing a majority of malicious committee members (such as verifiers); proof security evaluates the ability of DA bridge to verify data commitments without introducing additional trust assumptions. Exit window standards examine the upgradability of DA bridge, with particular attention to withdrawal mechanisms and the time allowed for users to exit during upgrades.
