Mempool Congestion

Definition ∞ Mempool congestion occurs when the number of unconfirmed transactions waiting to be processed in a blockchain’s memory pool exceeds the capacity of available block space. This backlog leads to increased transaction fees and slower confirmation times for users. It is a direct result of high network demand surpassing the network’s processing capabilities.
Context ∞ News about blockchain networks frequently discusses mempool congestion, particularly during periods of high market activity or network stress. This condition impacts user experience and highlights scalability limitations for various cryptocurrencies. Developers continually seek solutions through protocol upgrades and layer-two technologies to alleviate congestion and improve network efficiency.
