Transaction Spam

Definition ∞ Transaction Spam refers to the deliberate flooding of a blockchain network with numerous low-value or meaningless transactions. This activity aims to congest the network, drive up transaction fees, or test the network’s resilience. Attackers typically send a large volume of transactions, often to themselves, consuming block space and processing power. While costly for the attacker, successful spam can degrade network performance and user experience.
Context ∞ Transaction Spam remains a recurring issue for various blockchain networks, particularly those with fixed block sizes or high demand. Discussions revolve around implementing effective fee markets and dynamic block size adjustments to mitigate its impact. Future developments include advanced mempool management, transaction batching, and layer-2 scaling solutions designed to absorb high transaction volumes more efficiently.
