How does Kaspa solve the Bitcoin scaling problem?

Kaspa solves the Bitcoin scaling problem by using an inclusive protocol that lets each block point to multiple previous blocks instead of just one. In a traditional blockchain, miners must slow down block creation to allow blocks time to propagate across the network — produce blocks too fast and the chain forks, wasting work. Kaspa's inclusive protocol removes that bottleneck: because a block can reference several predecessors simultaneously, the network structure tolerates rapid block production without the forks that would normally undermine security. The result is that Kaspa's block creation rate can exceed the network propagation time while still maintaining security — something a single-chain design cannot do.
