Arbitrum has initiated a temperature check proposal to upgrade Arbitrum Sepolia to ArbOS 30 'Bianca', a significant development that aims to enhance the platform's performance and efficiency. The proposed upgrade includes the introduction of Stylus and the activation of MultiVM, which will unlock ten times cheaper computation and memory through the use of Rust smart contracts.

The inclusion of Stylus and MultiVM in the ArbOS 30 'Bianca' upgrade is expected to revolutionize the way computation and memory are handled on the Arbitrum platform. By leveraging Rust smart contracts, users will benefit from a tenfold reduction in costs, making the platform more accessible and cost-effective for a wider range of applications.

Moreover, the upgrade will maintain full interoperability with EVM (Ethereum Virtual Machine), ensuring that the upgraded system can interact seamlessly with the Ethereum ecosystem. This interoperability is crucial for the widespread adoption and integration of Arbitrum, as it allows for seamless integration with existing Ethereum-based applications and infrastructure.

The proposed upgrade to ArbOS 30 'Bianca' is a testament to Arbitrum's commitment to innovation and continuous improvement. By introducing cutting-edge technologies like Stylus and MultiVM, Arbitrum is positioning itself as a leader in the Layer 2 scaling solutions space, offering users a more efficient and cost-effective alternative to the Ethereum mainnet.

In conclusion, the Arbitrum Sepolia upgrade to ArbOS 30 'Bianca' is a significant milestone in the platform's development. By introducing Stylus and MultiVM, Arbitrum is poised to revolutionize the way computation and memory are handled on Layer 2, while maintaining full interoperability with the Ethereum ecosystem. This upgrade is expected to drive further adoption and growth of the Arbitrum platform, solidifying its position as a key player in the decentralized finance (DeFi) space.
