Flashbots Warning: MEV Bots spam activities are hindering mainstream chain expansion.

Gate News bot news, focusing on the research institution Flashbots regarding MEV (Maximum Extractable Value), recently issued a warning that spam from MEV Bots is rapidly becoming a major obstacle to Blockchain scalability.

Flashbots pointed out in a paper published this week that “MEV has become a major limiting factor for Blockchain scalability,” and noted that the efficiency of Ethereum rollups and Solana is declining. The current scalability efforts of mainstream blockchains are being offset by the increasingly prevalent MEV-driven activities.

As Layer 1 and Layer 2 networks compete to increase throughput, reports have found that the on-chain activities of MEV Bots are wasting an increasing amount of available capacity.

On Solana, MEV Bots currently occupy 40% of all Block space. On Ethereum’s OP-Stack Rollup (such as Base and OP Mainnet), spam Bots account for more than half of the Gas usage, while the fees paid only constitute a small portion of the network costs.

The report points out that between November 2024 and February 2025, Base added a throughput of 11 million Gas units per second, nearly three times that of the Ethereum mainnet. However, most of this new capacity was consumed by Bots executing low-value repetitive transactions. This behavior artificially inflated user fees and reduced the efficiency of technical scaling efforts. Flashbots introduced a new metric—“effective Gas throughput”—to illustrate this discrepancy.

On Base, Bots accounted for 56% of Gas usage and 26% of Layer1 data availability usage, but only paid 14% of the fees.

Spam has also driven up user fees. Flashbots explained that although technology has made progress in reducing rollup costs, fees remain artificially high due to bots continuously bidding for block space.
