According to Odaily, Arbitrum has initiated a temperature check proposal to upgrade Arbitrum Sepolia to ArbOS 30 'Bianca'. This upgrade includes Stylus and enables MultiVM, unlocking ten times cheaper computation and memory through Rust smart contracts, while maintaining full interoperability with EVM.

The proposed upgrade to ArbOS 30 'Bianca' is a significant development for Arbitrum. The inclusion of Stylus and the activation of MultiVM will allow for more efficient and cost-effective computation and memory usage. The use of Rust smart contracts will further enhance these capabilities, providing a tenfold reduction in costs.

In addition to these improvements, the upgrade will also ensure full interoperability with EVM. This means that the upgraded system will be able to interact seamlessly with EVM, further enhancing its functionality and usability. This development is expected to significantly improve the performance and efficiency of the Arbitrum platform.
