What does it mean for a Kaspa block to have multiple parents?

In Kaspa's BlockDAG, each block can point to more than one previous block as its parent, forming a web of connections rather than a single line. In a traditional blockchain, every block has exactly one parent — the block directly before it — so the history looks like a single chain. Kaspa breaks that constraint: when a new block is created, it can reference several existing blocks simultaneously, weaving them together into a connected graph of relationships. For a beginner, this means the network records far more activity at once, because blocks don't have to wait in line behind each other.
