The text discusses the development of a scalable and Miner-Extractable Value (MEV)-resistant decentralized finance (DeFi) ecosystem using Arbitrum's layer-2 rollups and Chainlink's Fair Sequencing Services (FSS). Rollups are highlighted as a key solution for scaling the Ethereum network by moving transaction computations off-chain while maintaining security through the layer-1 blockchain. Despite their scalability benefits, rollups still face MEV issues, which arise from miners manipulating transaction order for profit. To address this, Chainlink is developing FSS to ensure fair and predictable transaction ordering, thereby enhancing trust. Arbitrum, a leading layer-2 rollup, is noted for its efficient fraud-proof mechanisms and compatibility with Ethereum, and it is actively exploring FSS integration to reduce MEV and improve transaction fairness. This collaboration aims to decentralize Arbitrum's sequencer, mitigate MEV, and provide a robust scaling solution for Ethereum, potentially supporting billions of users and diverse applications.
