MEV Bots Drive Blockchain Congestion Reports Flashbots

Blockchain Congestion and MEV Bots Impact in 2025

Flashbots reports that MEV bots are largely responsible for blockchain congestion, surpassing network scalability efforts, affecting Ethereum and Solana as of June 2025.

The escalation of MEV bot activity underscores the necessity for systemic changes to restore blockchain efficiency and mitigate associated costs impacting major networks.

MEV Bots Consume Over Half of Blockchain Gas

Flashbots released a report indicating MEV bots are consuming major blockchain capacity, causing serious congestion issues. The report corroborates similar problems across high-throughput blockchains, including Ethereum and Solana. The findings highlight inefficiencies, with MEV bots using over 50% of available gas. Flashbots calls for auction design changes to combat the ongoing challenge faced by industry stakeholders.

Fee Increases Highlight Urgent Need for Reform

Immediate effects include increased gas fees and reduced network utility for Ethereum and Solana users. This inefficiency highlights the need for concerted industry efforts to address the spamming issue. Economic implications are significant, driving costs up for users and affecting the valuation of tokens like ETH and SOL. Investor sentiment reflects growing concerns over prolonged scaling limitations.

“MEV has become the dominant limit to scaling blockchains. Spectacularly wasteful onchain searching is starting to consume most of the capacity of most high throughput blockchains.” — Flashbots Writing

Systemic Auction Redesigns Proposed to Alleviate Congestion

Comparisons to the 2020–2021 crisis reveal persistent MEV issues despite previous mitigation attempts. Flashbots’ historical solutions have been inadequate against current bot-induced congestion. Proposed market reforms aim at creating new economic structures to alleviate congestion. Past trends indicate potential solutions hinge on systemic auction redesigns and reinforced protocol measures.
