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.

ChainCatcher news, OKX Ventures announced the completion of a strategic investment in 0G. 0G (formerly Zero Gravity) is a programmable high-speed data availability protocol for on-chain artificial intelligence scenarios. This decentralized protocol features large-scale high concurrency and high security.Whether in scenarios for large-scale applications in the Web3 industry or under the technical framework of the Ethereum mainnet upgrade Proto-Danksharding / EIP-4844, Data Availability (DA) plays a crucial role.Based on different storage scenarios, such as on-chain storage, off-chain execution, and hardware node upgrades, data availability solutions are competing fiercely. The highlight of 0G is the reduction of transaction costs by 10000%, truly achieving high scalability.Dora Yue from OKX Ventures stated: "0G achieves a performance throughput of 50GBs with extremely low latency by decoupling storage from consensus. Its innovation lies in helping to solve the capabilities of smart contracts with machine learning through zero-knowledge proof (ZK) + artificial intelligence (AI), optimizing Web3 sectors such as DeFi, security, authentication, Web3 social, and creator economy, leveraging its programmable, high-performance, and scalable characteristics. Against the backdrop of the Ethereum block size being reduced to 25mb, 0G has conducted in-depth cooperation with other public chains like Polygon. Its modular technology stack deployment has been recognized by traditional giants like Microsoft / Meta. The efficient application of on-chain data and the combination of deep neural network computing help the blockchain industry unleash more potential in various technical foundations such as Rollup as a Service (RaaS) and AI integration scenarios. We are very much looking forward to the mainnet launch in the second half of the year!"
