According to @ItsDave_ADA, the recent Cardano proposal introduces a centralized pre-mempool where a single entity oversees and manages transactions before they reach public Cardano nodes. This change could impact ADA trading by increasing the risk of transaction censorship, front-running, and reducing network transparency, which may affect trader trust and market liquidity. Such centralization could also lead to concerns over network security and potential manipulation, making it a critical development for ADA holders and active traders to monitor closely (source: @ItsDave_ADA).
