RBuilder：一个基于Reth的MEV构建器

Ferran from Flashbots introduced the ArtBuilder, a new modular block building stack designed to enhance the efficiency and innovation of block building processes. The ArtBuilder leverages the Proposal Builder Separation (PBS) model, allowing builders to create blocks while proposers select the highest bids through a metboot relay. The R Builder, built on the Red framework, aims to simplify the development of custom sorting and merging algorithms without the complexities of forking and merging code. Key features include modular block building, backtesting capabilities, and a local deployment environment for easier testing. Future developments will focus on multi-chain support, improving block builder architecture, enhancing performance, and launching a block building competition to foster innovation in the space.
