A searcher oracle is a specialized data feed or service that provides information to market participants, particularly “searchers” in the context of Miner Extractable Value (MEV), regarding pending transactions and their potential profitability. This oracle supplies data that helps identify arbitrage opportunities, liquidation events, or other profitable sequencing strategies. It serves as a tool for optimizing transaction inclusion in blocks.
Context
The role of searcher oracles is a subject of ongoing debate within the blockchain community, particularly concerning their contribution to MEV extraction and its impact on network fairness. Discussions address the transparency and decentralization of these oracle services. Future developments aim to integrate fair sequencing mechanisms that diminish the advantage gained from such oracles, promoting a more equitable transaction environment.
Introducing the SAKA mechanism, this work circumvents TFM impossibility results by integrating MEV searchers to align incentives and guarantee approximate welfare.
