Blockchain transaction sorting is evolving into an "application-aware" phase, driven by increasing transaction volumes and heightened competition. This development is crucial as transaction sorting impacts price spreads, liquidity depth, and miner extractable value (MEV), making it a key area for market makers. Innovations such as Hyperliquid’s consensus-level sorting, Solana’s ACE and BAM, and Chainlink’s SVR are designed to mitigate front-running and enhance efficiency. These advancements are expected to stabilize market behavior and improve transaction fairness, especially as the fear and greed index remains volatile.
