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, enhancing the blockchain network’s censorship resistance.
The MCP mechanism has gained attention in various blockchain ecosystems: Ethereum plans to reduce its reliance on MEV-Boost through MCP; Solana is advancing the implementation of MCP by combining Application-Specific Sorting (ASS), and the Alpenglow upgrade plan further optimizes validator costs; Cosmos is exploring MCP using a BFT model and secure broadcast protocol; Sei has designed a separation of data availability and sorting functions based on Autobahn; Delta adopts a concurrent sorter to achieve application-specific sorting.
The current implementation of MC faces technical challenges such as sorting competition, invalid transaction processing, increased hardware requirements, and finality synchronization.
