Definition ∞ Transaction spamming refers to the act of flooding a blockchain network with a large volume of low-value or unnecessary transactions. This activity can intentionally or unintentionally cause network congestion, increase transaction fees, and slow down processing times for legitimate users. It can be a form of denial-of-service attack or a side effect of inefficient application design.
Context ∞ News reports frequently address transaction spamming as a significant challenge for blockchain scalability and network usability, particularly for public, permissionless ledgers. Developers continually work on protocol upgrades and fee mechanisms to mitigate the impact of such activities. Understanding this issue is important for assessing the operational efficiency and resilience of various blockchain networks.
