Definition ∞ A Block Size Increase refers to a modification of a blockchain protocol that permits more transaction data within each block. This adjustment aims to augment the network’s capacity for processing transactions, thereby improving scalability. Larger blocks allow for a greater number of transactions to be confirmed in a single batch, potentially reducing transaction fees and confirmation times. Such changes typically necessitate a consensus among network participants to be implemented.
Context ∞ Discussions surrounding block size increases often focus on the trade-offs between scalability and decentralization. While a larger block size can boost transaction throughput, it may also lead to increased hardware requirements for nodes, potentially concentrating network control among fewer, more powerful entities. This remains a central point of contention in various blockchain communities, influencing debates on network upgrades and future development paths.
