A new report from Flashbots has warned that maximum extremable value (MEV) quietly becomes one of the largest roadblocks for scaling.
According to the research, “spam auctions” driven by MEV-seekers systematically use the majority of the new capacity on high-throUghput chains such as Solana and Ethereum Layer-2S (L2S), neutralization of scale wins and increasing user costs.
The scale of waste -induced waste
MEV, the extra profit miners or bots can extract by re -organizing transactions, has long been controversial. But the newest deep dive from Flashbots shows that the problem has escalated from an ethical debate to a measurable resistance to blockchain achievements.
Analyzing data from Op-Stack rollups such as Base and Optimism Mainnet, in addition to findings from Solana, showed the Flashbots survey how high-frequency arbitration bots flood networks with countless speculative transactions looking for fast profit.
According to researcher Bert Miller, Bots on Solana use around 40% of the blockspace and contribute only 7% of the total reimbursements. Meanwhile, on Ethereum L2s such as Base and on -Mindet, spambots are said to eat more than half of the available gas, but pays a fraction of the costs compared to legitimate users.
Miller shared a grim example on X: Between November 2024 and February 2025, the base raised its transit by 11 million gas per second, about the same as three Ethereum minnettes, only to see that almost all of it was absorbed by spambots.
He emphasized that the core issue lies in how the bots work. Usually private mempools, designed to protect their users against front tuning, leaving MEV-seekers blindly for real-time order flows. Therefore, in order to remain competitive, these bots tend to use complex transactions in the chain to investigate arbitration, resulting in mountains of wastage calculation when there is no profit.
Miller noted that one successful two-hop arbitration can cost no less than 132 million gas in failed attempts, which is about the size of four Ethereum blocks per victory.
According to him, this dynamic means that although blockchains can technically expand the transit, MEV -Spam creates an economic ceiling that makes rough improvement inefficient and expensive for everyone. The statement of the flashbots called this the “dominant limit for the scaling of block chains” and suggested revising how networking deals with transaction order.
Path to economic efficiency
The proposed solution of the research organization combines ‘programmable privacy’, which gives seekers sufficient visibility to prevent spam and to protect users against predatory strategies, with explicit offering for transactional priority. In this way it is of the opinion that the competition will shift from brute-force spamming to transparent, price-based auctions.
In another X -post, Miller revealed that some early experiments, such as the use of Trusted Execution environments (TEEs) to enforce bone behavior, are already live. Last year his countryman Angela Lu announced that Flashbots had performed tests, where they embedded a bone in a secure enclave, allowing the reliable arbitration opportunities to catch and prevent malignant tactics such as sandwich attacks.
Only recently did the former Binance CEO Changpeng Zhao drove the idea of dark pools with the help of zero knowledge certificate to prevent the MEV threat in the decentralized financial (Defi) space. In addition, Blockchain Oracle Provider Chainlink introduced a solution last year called Smart Value Recapture (SVR) that would enable Defi apps to win back “non-toxic” MEV.
If refined, such innovations can hopefully transform MEV from a hidden drain into a source of sustainable income for chains, while the costs for everyday users are lowered.
