Offchain Labs releases Arbitrum technology roadmap, focusing on Stylus, decentralized sorting, ZK proofs, etc.

According to official sources, Offchain Labs, the developer of Arbitrum, has released a future technology roadmap that includes interoperability and horizontal scaling, decentralized sorting, ZK proofs, and Stylus (MultiVM support). The key points are as follows:

- Stylus will be launched on Arbitrum One and Nova mainnets in early September 2024, supporting WASM languages such as Rust, C, and C++, allowing any Arbitrum chain with Stylus to support both EVM and WASM VM with full interoperability between the two.

- BoLD and audit timeout features will be launched in the second half of 2024 to increase security and decentralization, bringing Arbitrum closer to Stage 2 rollup.

- Decentralized sorter is expected to be implemented in 2025, decentralizing transaction sorting responsibility to reduce the risk of audit attacks and increase reliability.

- Fast withdrawal function will be launched in Q3 2024, allowing peer-to-peer communication between L2 and L3, enabling developers to horizontally scale.

- Chain Clusters are planned to be launched in 2025, aiming to reduce cross-chain communication time.

In addition, Offchain Labs also plans to achieve multi-client support and adaptive pricing mechanisms in the first half of 2025, and is actively researching the integration of zero-knowledge proof technology into the Arbitrum chain, with ZK+Optimistic hybrid proof being an active area of research.
