How efficiently does Kaspa use mining energy for network security?

Per unit of energy spent, Kaspa extracts far more security value than traditional single-chain proof-of-work designs. In single-chain systems, blocks mined in parallel are discarded as orphans, meaning the energy behind them contributes nothing to security. Because GHOSTDAG preserves parallel blocks rather than orphaning them, Kaspa keeps that mining effort working for the network instead of discarding it. For a beginner, this means the electricity that miners spend securing Kaspa is used more completely — most of it actually strengthens the network rather than being lost to orphaned blocks.
