Flashbots: MEV robots block blockchain faster than network expansion speed According to The Block, research firm Flashbots has released a report warning that MEV (Maximum Extractable Value) has become the main limiting factor for blockchain scalability. The report points out that the garbage transactions generated by MEV robots are consuming block space at a rate exceeding network expansion, leading to the failure of technological breakthroughs in raw throughput. Research has found that garbage robots consume over 50% of gas fees on mainstream OP Stack Rollup but only pay less than 10% of transaction fees, pushing up the basic transaction costs for ordinary users. Among them, Coinbase's Base network is the most severe, with two robots contributing over 80% of junk transactions. This issue also exists in networks such as Solana, where MEV robots occupy approximately 40% of block space. The report suggests that economic congestion (rather than technological bandwidth) has become an actual bottleneck for capacity expansion, and the existing market structure of "junk trading auctions" has exacerbated this problem. Flashbots proposes to reform the existing bidding mechanism and adopt off chain auction schemes to reduce network congestion and lower costs.
