        This research introduces a time-advantage auction mechanism, fundamentally altering how Maximal Extractable Value is distributed and potentially enabling fairer transaction ordering.
        
        Optimistic MEV Dominates L2 Blockspace with Speculative Arbitrage Probes
        
        
        
        
          
        
        
      
        
    
        
        This research quantifies "optimistic MEV," a novel on-chain arbitrage strategy, revealing how speculative smart contract probes saturate Layer 2 blockspace despite low transaction fees, reshaping network economics.
        
        Optimistic MEV Strategies Exploit L2 Incentives, Impacting Network Efficiency and Security.
        
        
        
        
          
        
        
      
        
    
        
        Research reveals "optimistic MEV" as a dominant L2 arbitrage, where speculative on-chain probing crowds out user transactions and exposes rollup security vulnerabilities.
        
        Optimal MEV Arbitrage Splits Trades on Fast-Finality Blockchains
        
        
        
        
          
        
        
      
        
    
        
        This research reveals that arbitrageurs on fast-finality blockchains maximize profit by splitting MEV opportunities into small, spam-based transactions, exposing critical flaws in current fee mechanisms.
