ChainCatcher news, according to official sources, modular data solution provider CARV has announced a strategic partnership with the Bitcoin-secured consumer network Nubit.This collaboration aims to combine CARV's modular data layer with Nubit's data availability (DA) solution, enhancing the data availability and scalability of decentralized applications while eliminating barriers between Web2 and Web3.

ChainCatcher news, the open-source L2 data analysis website L2BEAT has introduced a risk framework aimed at assessing 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 map to the data proofs of the DA bridge published on Ethereum.The category of fraud detection mechanisms measures the effectiveness of user self-protection in the face of a malicious majority of committee members (such as validators); proof security assesses the ability of the DA bridge to validate data commitments without introducing additional trust assumptions. The exit window criteria examine the upgradability of the DA bridge, with a particular focus on the withdrawal mechanism and the time allowed for users to exit during upgrades.
