Block Stuffing Attacks

Manipulation

Block Stuffing Attacks represent a form of network-level manipulation where an attacker floods the mempool or attempts to include a disproportionate number of low-value transactions within a block. This strategy aims to delay the confirmation of legitimate, high-priority transactions, such as those settling derivatives or large asset transfers. Such interference disrupts the expected market microstructure, creating opportunities for front-running or denial-of-service against time-sensitive trading strategies. The objective is often to profit from the resulting temporary price dislocations or to enforce a specific ordering of transactions.
