What does Kaspa's 2Dλ formula do?

The 2Dλ formula is how Kaspa turns the physical reality of internet geography into a mathematical safety guarantee for its consensus protocol. In the formula, the variables capture how long it takes blocks to propagate across the network and how fast blocks are being created. By plugging in those real-world numbers, the protocol can calculate exactly how much network delay it can tolerate before things go wrong. This matters for a beginner because it means Kaspa's security is not just theoretical — it is grounded in the actual physics of how fast data travels around the planet, connecting geographic reality to mathematical safety.
