What does the Crescendo Hardfork change about Kaspa's block rate?

The Crescendo Hardfork increases Kaspa's block production rate from 1 block per second to 10 blocks per second. Blocks Per Second (BPS) is how quickly new blocks are added to the network — a higher rate means more transactions can be processed in less time, but it also places greater demands on every node: more data to store and more bandwidth to consume. To keep the network efficient at this higher rate, several consensus parameters needed updating, including the sparse DAA window introduced in KIP-4, which was redesigned specifically to avoid wasting resources at 10 BPS. For a beginner, the practical takeaway is that Kaspa got ten times faster at producing blocks, bringing it significantly closer to the speed of everyday payment systems.
