Spam-based MEV, or Miner Extractable Value, refers to a specific strategy where validators or miners intentionally fill blocks with low-value, high-fee transactions to increase their revenue. This practice often involves front-running or sandwich attacks, where profitable transaction ordering is manipulated. It can lead to network congestion and degraded user experience.
Context
Spam-based MEV is a contentious topic in blockchain economics and network fairness discussions. News reports sometimes analyze the impact of such activities on transaction costs and network efficiency, particularly on high-demand blockchains. Efforts to mitigate its effects involve protocol adjustments and the development of more equitable transaction ordering mechanisms.
This research unveils how arbitrageurs strategically fragment transactions to exploit MEV on fast-finality rollups, exposing the limitations of current fee-based ordering.
