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)
