Definition ∞ A vertical scaling solution addresses blockchain throughput limitations by enhancing the capabilities of individual nodes within a network. This involves upgrading hardware, improving processing power, or optimizing software on existing machines. Rather than adding more nodes, vertical scaling makes each node more powerful. It aims to increase transaction capacity without altering the network’s fundamental structure.
Context ∞ Vertical scaling solutions are often discussed in conjunction with horizontal scaling methods as ways to improve blockchain performance. News reports may cover specific protocol optimizations or hardware advancements that allow nodes to handle greater loads. Understanding vertical scaling is important for assessing the underlying technological improvements that contribute to a blockchain’s overall efficiency and speed.
