ChainCatcher message, the Hummingbird client of the Ethereum L2 blockchain LightLink has launched on the Celestia mainnet, publishing L2 data to Celestia DA and verifying it, sending only the block headers to Ethereum. LightLink states that using Celestia as its data availability layer will reduce costs compared to Ethereum, allowing us to save costs for end users in the form of lower transaction fees.

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, the decentralized indexing protocol Hemera announced on X that Hemera has partnered with 0G Labs to launch BlobArchive, providing permanent data availability for L2. BlobArchive can store all data blobs created after the launch of EIP-4844 on Ethereum. Taiko is the first customer to retrieve blob data using this solution after EIP-4844.BlobArchive leverages cloud hosting and decentralized storage to create a decentralized solution with performance guarantees, featuring high performance, permanent storage, and easy verification.

This collaboration coincides with Mina's upcoming mainnet upgrade, which will bring a more user-friendly zkApp programming model, expected to significantly increase developer activity and the number of products in the Mina ecosystem.

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!"
