Why can't Kaspa nodes rely on external time references for consensus?

In Kaspa's distributed network, nodes cannot rely on external time references because doing so would introduce a dependency on sources outside the network's own consensus. A distributed system is one where many independent computers participate without any single point of control — if each node trusted a different external clock, or if one trusted time source were wrong or manipulated, the network would lose the shared agreement it needs to function. DAA Score addresses this by providing a time measure that emerges from the network itself. Understanding this helps beginners see why decentralization in crypto goes beyond just ownership — it extends to even basic infrastructure like timekeeping.
