EIP-7748 is now in a draft phase. The proposal aims to convert account states from the current Merkle Patricia Tree (MPT) data structure to the Verkle Tree (VKT) format. The solution would convert a fixed number of key values on a per-block basis to ensure a gradual transition, minimizing the impact on network performance and ensuring the process is manageable for clients. Verkle Trees are a more efficient and scalable data structure that offers smaller proof sizes and enhances the feasibility of stateless clients on Ethereum. They are a key component of The Verge upgrade in Ethereum's roadmap to simplify block verification. The transition to Verkle Trees is anticipated to be part of the Osaka upgrade.

Universal, a wrapped asset protocol, is now live on mainnet with initial support for Base. The protocol enables the trading of wrapped versions of non-EVM assets such as SOL, DOGE, and BTC on various blockchains. By using a mint-and-burn mechanism, Universal addresses the issue of liquidity fragmentation without relying on traditional bridging mechanisms. The protocol is operated by Custodians, who custody the the underlying assets, and Merchants, who serve as liquidity providers and facilitate the minting and burning. Universal aims to replicate CEX-level performance and pricing. The mainnet launch is currently in a beta phase, accessible by invitation only. Users can join a waitlist to participate in the beta release.

Syndicate, a provider of Web3 infrastructure, introduced metabased rollups, a new blockchain scaling design aimed at boosting decentralization and economic value for community-led Layer 3 networks. The rollups execute transactions outside of Layer 1 and post the transaction data back on the base layer. The sequencing in metabased rollups is managed by a smart contract on a layer beyond the L1. Similar to based rollups, metabased rollup sequencing occurs on and relies on the liveness of the chain’s parent layer, such as the L2. The design supports flexible sequencer configurations that offer scalability, cost-effective transactions, and economic alignment with the chain’s community.

Pre-sale tickets are now available for "Vitalik: An Ethereum Story," a community-funded feature documentary that explores the creation of Ethereum, Vitalik Buterin's journey, and the global community of builders. The documentary will be available for pre-release digital screening on September 20th and will be accessible until October 20th. Its mainstream release for all viewers is planned for early 2025.
