According to official news, Arbitrum developer Offchain Labs released a future technology roadmap, including interoperability and horizontal expansion, decentralized sorting, ZK proof and Stylus (MultiVM support), etc. The main points include:
-Stylus will be launched on the Arbitrum One and Nova mainnets in early September 2024, supporting WASM language development such as Rust, C and C++; this will allow any Arbitrum chain with Stylus to support EVM and WASM VM, with full interoperability between the two;
-BoLD and review timeout functions will be launched in the second half of 2024, improving security and decentralization, bringing Arbitrum closer to Stage 2 rollup;
-The decentralized sorter is expected to be implemented in 2025, dispersing transaction sorting responsibilities, thereby reducing the risk of censorship attacks and improving reliability;
-The fast withdrawal function will be launched in Q3 2024, making the same level L2 and L3 Able to communicate with each other quickly, allowing developers to scale horizontally;
-Chain Clusters is scheduled to be launched in 2025, aiming to reduce cross-chain communication time.
In addition, Offchain Labs also plans to implement multi-client support and adaptive pricing mechanisms in the first half of 2025, and is also actively researching the integration of zero-knowledge proof technology into the Arbitrum chain. An active area of research is ZK+Optimistic hybrid proof.
