How does Kaspa fix the weakness in Bitcoin's 51%-attack threshold?

In Bitcoin-style blockchains, a 51% attack actually requires less than 51% of total hashing power, because honest miners constantly waste work on orphaned blocks — Kaspa's GHOSTDAG eliminates this by letting all parallel blocks count. When two miners find a block at roughly the same time, traditional chains discard one (called an orphan), wasting the computing effort behind it. An attacker exploits this: they only need to outpace the honest network's effective output, not its total. Since honest work keeps getting thrown away, the real attack threshold is lower than 51%. Kaspa keeps all parallel blocks in play, so no honest work is wasted and the full network hash rate defends the chain. For a beginner, this means Kaspa closes a real security gap that exists in Bitcoin-style chains, not just in theory.
