Block size refers to the maximum amount of data that can be included in a single block on a blockchain. This is crucial because it directly impacts the efficiency and capacity of a blockchain to process transactions, influencing both speed and costs associated with executing smart contracts. Understanding block size helps address challenges related to gas optimization and scalability in blockchain networks, as larger blocks may lead to increased transaction throughput but can also create bottlenecks in processing and validation.
