ChainCatcher news, Layer2 cross Rollup bridge Orbiter Finance R&D engineer ZeroKPunk tweeted that recently a single Fibonacci Cairo1.0 program's POC verification was completed with a relatively low Gas cost (about 290000 Gas). Currently, developers may have to submit and verify their Cairo programs through SHARP. However, an alternative has now been provided, allowing developers to prove locally, deploy their own Cairo Verifier contracts, and verify at a relatively low Gas cost.

ChainCatcher news, ConsenSys L2 network Linea launches the Linea Ecosystem Investment Alliance (EIA), which is a consortium of over 30 venture capital firms including Amber Group, Animoca Brands, BlockTower Capital, Fenbushi Capital, Huobi Ventures, IOSG Ventures, etc. This alliance will support projects that utilize Linea to reshape applications in areas such as finance and payments, gaming and entertainment, community and identity.

ChainCatcher news, Paradigm released the announcement "Collaborate with Paradigm," stating that it hopes to collaborate with more outstanding talents in the crypto field and plans to engage in deep cooperation with 3 to 5 new projects. Paradigm will provide funding and resource support for them. It calls on entrepreneurs or projects in the seed stage or Series A funding stage to fill out a form to introduce their projects to Paradigm.In addition, Paradigm announced 10 areas in the crypto field that it has been exploring: intent-centric protocols and infrastructure, Hooks based on Uniswap v4, infrastructure for a Rollup-centric multi-chain world, shared sequencers, on-chain gaming, crypto-native social applications, prediction markets, stablecoin payments/fintech, on-chain vaults, ZKP applications.

ChainCatcher news, the Voyager Quest challenge initiated by the zk-rollup network Linea has officially concluded. The nine-week challenge aimed to engage its community and test its technology. During the challenge, Linea achieved over 30 million transactions, with more than 5.2 million wallets participating, showcasing the strength of its ecosystem.Voyager Quest allowed participants to engage in various on-chain and off-chain activities, including Q&A and voting, to learn more about the Linea ecosystem and its features. The Linea team upgraded key components of the zkEVM architecture, improving network performance, user experience, and transaction costs, laying the foundation for a more scalable, efficient, secure, and user-friendly Ethereum Layer 2 roll-up network.

The new version will bring significant improvements to the sequencer, including sequencer performance, cancellation of Pending status, and block hash system calls. (source link)

ChainCatcher news, zkSync announced the launch of a modular open-source framework called ZK Stack for building custom zkRollups. ZK Stack will empower developers with complete autonomy, from choosing data availability models to using their own tokens for decentralized ordering.It is reported that ZK Stack offers two key features: sovereignty and seamless connectivity. Creators have full rights to the code and enjoy unrestricted autonomy to customize and shape various aspects of the zkRollup chain. These zkRollup chains operate independently, relying solely on Ethereum L1 for their activity and security, while cross-chain bridges exist to facilitate interconnection between each chain, achieving trustless, fast (within minutes), and low-cost (per transaction) interoperability.
