Definition ∞ Block Throughput quantifies the number of transactions a blockchain network can process and confirm within a specific time period. It serves as a key performance indicator for network scalability. Higher block throughput indicates a greater capacity to handle transaction volume. This metric is often measured in transactions per second.
Context ∞ Improving block throughput remains a central challenge for many public blockchain networks, directly impacting transaction fees and confirmation times. Layer-two scaling solutions, such as rollups and sidechains, are actively developed to augment this capacity. Enhancing throughput is critical for supporting widespread adoption of decentralized applications and digital payments.
