Optimism Highlights 🔴✨
Zora Launches L2 Built On OP Stack
NFT minting platform Zora launched Zora Network, a new L2 network built on the OP stack. The launch includes an RPC endpoint, a block explorer, and a native bridge. Zora Network is live on mainnet and integrated directly into existing tools on the platform. The new L2 provides users with access to scalable mints and low-gas transactions. Zora is a hub for artists to express and experiment with multimedia NFTs. Zora already supports NFT minting on Optimism and Ethereum Mainnet. Zora Network joins BASE, opBNB, and Optimism Mainnet as the fourth chain to join the Superchain. Zora co-founder Jacob Horne stated that a token is also part of the project’s vision.
Optimism Announces RetroPGF Round 3
Optimism announced its third retroactive public goods funding round, allocating a total of 30 million OP tokens to public goods projects. The allocation marks a 3x increase from round 2, which distributed 10 million OP tokens earlier this year. Project nominations will open over the summer with funds to be distributed in the Fall. RetroPGF Round 3 features four project categories, including the OP Stack, Collective Governance, Developer Ecosystem, and End User Experience and Adoption. Allocation of funding will be decided by Citizens’ House badgeholders, who are community members with voting privileges. The funding comes from the initial OP token supply and profits generated by the Optimism sequencer.
Arbitrum Orbit Quickstart Guide
Offchain Labs published a quick start guide for building on Orbit, a tech stack for launching L3 chains on Arbitrum One and Nova. The guide explains how to deploy an Orbit local devnet chain that can host EVM-compatible smart contracts and settle transactions on Arbitrum Goerli. At least 1.5 Goerli ETH is required for a devnet deployment. Arbitrum Orbit also supports WASM smart contracts, allowing developers to code in high-level languages such as C++ and Rust. Developers are free to customize and modify source code as they see fit for L3 deployments on the Arbitrum rollup. Offchain Labs also plans to release guides for deploying production-ready Orbit chains.
Verkle Tries Information Hub
Ethereum developers Josh and Guillaume launched verkle.info, an information hub for Verkle Tries. Verkle Tries are a new data structure that provide smaller proof sizes and make stateless clients on Ethereum more feasible. They are also part of The Verge upgrade on Ethereum's roadmap, which will simplify block verification. A Verkle Trie implementation is currently drafted under EIP-6800, which seeks to introduces a new Verkle state tree alongside the existing Merkle Patricia Tree.
