What is pruning in Kaspa and why does it exist?

Pruning is the mechanism that keeps Kaspa's storage requirements bounded regardless of how old the chain becomes. A blockDAG running at 10 blocks per second generates data extremely quickly — without pruning, that data would accumulate without limit, making it progressively harder for ordinary people to store and run a node. Kaspa's design addresses this directly, so the storage footprint stays manageable over the long term rather than growing forever. This matters for beginners because it means participating in the Kaspa network does not require ever-larger or more expensive hardware as the chain ages.
