Recently, multiple users discovered an image model named luna-lisa-alpha appearing on the LMArena testing platform, suspected to be a new generation image generation model that OpenAI is testing. Although not officially confirmed, there is speculation that it could be an early version of GPT Image 2.5 or the next generation of GPT Image.From the testing feedback, the new model shows significant improvements in character consistency, image realism, text generation capability, and noise control. Some testers compared it with models like GPT Image 2.0, Nano Banana Pro, and Grok Imagine, believing that luna-lisa-alpha can better maintain the appearance, clothing, and style of the same character across multiple generations. However, some testers pointed out that there are still issues with repeated textures in complex texture areas. On the same day, OpenAI announced that the GPT Image 2 API preview supports transparent background generation, which can be used for product images, web design, and other scenarios. The exposure of multiple checkpoint names has also led the community to speculate that OpenAI may be conducting A/B testing. Whether this model will be officially released remains uncertain, and we need to wait for official information from OpenAI.

ChainCatcher news reports that, according to official sources, the Bitcoin native DA layer Nubit Pre-Alpha testnet will complete testing at 7 AM Beijing time on April 17.It is reported that Nubit previously launched a waitlist activity for the Pre-Alpha testnet. Participants need to connect their wallets and obtain an invitation code to accumulate 2000 points, which can unlock Gas coupons for paying transaction fees on the Nubit DA layer. Waitlist points can be earned through referring friends, holding BRC20 tokens, and Ordinals NFTs.According to the crypto data platform RootData, Nubit completed a $3 million Pre-Seed funding round in March this year, with investments from dao5, OKX Ventures, Primitive Ventures, and others. This round of financing is a key step for Nubit in establishing the first Bitcoin native data availability layer and aims to lead the modular paradigm shift in the Bitcoin ecosystem.

ChainCatcher news, the decentralized ZK-RaaS platform Opside has announced the opening of the whitelist application for POW miners and developers' faucet.It is reported that Opside launched the PoS whitelist pre-application activity last week, and the current opening of the PoW and developer whitelist pre-application activity will officially start at 18:00 Beijing time on May 8, 2023. After the opening, both PoW miners and developers can go to the Opside official website faucet to apply for the whitelist. Eligible users can later access the designated Faucet channel on Opside Discord to receive Opside test tokens as soon as possible.Opside officials stated that this round of applicants will undergo a certain degree of screening. POW miners need to provide detailed information about their previous mining experience, while developers need to provide their GitHub link and relevant development experience, etc. (source link)

ChainCatcher news, the decentralized ZK-RaaS platform Opside has publicly unveiled its tokenomics for the first time, with 33% allocated to PoS and PoW rewards. Opside provides a unified ZKP computing power market for numerous ZK-Rollup/zkEVM to incentivize miners to participate in ZKP computation. The article also explains the economic model of the PoS&PoW hybrid consensus.It is reported that Opside will launch a Pre-Alpha incentivized testnet in May, and the pre-application for validator nodes on the Pre-Alpha testnet officially started on May 2. It will gradually support one-click deployment and fully managed hardware services for zkEVM open-source solutions such as Polygon zkEVM, Scroll, zkSync, and Taiko. (source link)

ChainCatcher news, the three-layer architecture ZK-RaaS platform Opside's official website shows that the Pre-alpha testnet will be launched in May. Meanwhile, according to the article "Opside Incentive Testnet Preview," the Pre-Alpha testnet aims to test a hybrid of PoS and PoW consensus, test the ZK-Rollup launch base, complete Opside's ETH2.0 consensus adjustment, establish a usable ZK-Rollup execution environment and enrich the application ecosystem, and support various methods to facilitate asset flow between different layers and ZK-Rollups.The Alpha testnet is expected to launch in August, aiming to achieve the decentralization of ZK-Rollup proof nodes, a complete PoW mining mechanism, the decentralization of sequencers, and a cross-Rollup communication mechanism. The final testnet is expected to launch in November. (Source link)

ChainCatcher news, at the 2023 Hong Kong Web3 Carnival "Web3 Technology Infrastructure: Layer 2 Networks" forum, NanFeng, co-founder and CEO of the decentralized ZK-RaaS platform Opside, delivered a speech titled "Opportunities and Challenges of RaaS."NanFeng stated that the development of public chains has currently transitioned from the multi-chain era to the multi-Rollup era. Opside has completed a seed round of financing of 4 million USD and is currently advancing in an orderly manner according to the latest technical roadmap. Opside will launch its Pre-Alpha testnet in Q2 of this year, while continuously completing the preliminary construction of the three-layer architecture and ecological projects, with plans to officially launch the mainnet next year.As a platform focused on ZK-Rollup as a service (ZK-RaaS), Opside has designed a three-layer architecture based on base chain + based rollup + decentralized prover to address challenges such as Rollup still being limited by underlying L1, lack of sovereignty in applications, data availability layers, lack of security and decentralization, and the need for project parties to build their own ZKP computing capabilities. Additionally, it has innovatively introduced a hybrid consensus mechanism of PoS + PoW.

ChainCatcher news, based on zk, the three-layer blockchain Opside will launch its Pre-Alpha testnet in the second quarter, with the main goal of completing a three-layer network based on "Ethereum testnet - Opside (PoW & PoS) - zkRollup (RaaS)'' to provide a testing environment for early applications. The initial version of the testnet is currently open on the official website, and some DeFi and gaming applications will use ZK-RaaS deployed on Layer 3.It is reported that for the current zk-rollup execution environment, Opside provides solutions such as Polygon's zkEVM and Delphinus Labs' zkWasm, and based on these zkVMs, it has unified the smart contract interface, increased Rollup slots, and established a cross-Rollup communication mechanism. Each application in the ecosystem can obtain a Rollup slot through auction and leasing mechanisms, thus registering a native rollup and becoming the exclusive execution environment for that application. Opside also offers two bridging solutions, one based on multi-signature technology and the other a decentralized liquidity bridge. The team will continue to develop zkbridge. (Source link)
