Dynamic Block Size refers to a flexible protocol feature that allows the size of blocks in a blockchain to change based on network demand. Unlike a fixed block size, which can lead to congestion during peak usage, dynamic block size adjusts the capacity to accommodate more transactions when necessary.This adaptability helps maintain transaction speed and lowers fees during times of high activity. When fewer transactions occur, the block size can reduce, optimizing space and resources on the blockchain.The mechanism for dynamic block size typically involves algorithms that assess the current network load. As demand increases, the system can create larger blocks to process more transactions, and conversely, it can downsize when activity decreases.Overall, this approach aims to enhance scalability and improve user experience by allowing for a more resilient and responsive network. By balancing capacity and efficiency, dynamic block size can help maintain the integrity and functionality of a blockchain over time.
