According to Gate News bot, @0xRainandCoffee published an article introducing the Multi-Concurrent Proposer (MCP) mechanism. This mechanism supports multiple proposers to simultaneously propose sub-blocks and merge them to enhance the censorship resistance of the blockchain network.
The MCP mechanism has gained attention in major Blockchain ecosystems: Ethereum plans to reduce reliance on MEV-Boost through MCP; Solana is advancing the implementation of MCP with Application Specific Sorting (ASS), and the Alpenglow upgrade plan further optimizes validator costs; Cosmos explores MCP using the BFT model and secure broadcast protocol; Sei separates data availability and sorting functions based on Autobahn design; Delta adopts concurrent sorters to achieve application specific sorting.
Current MCP implementation faces technical challenges such as sorting competition, invalid transaction processing, increased hardware requirements, and finality synchronization.
