There's a second way propagation turns into money, and it gets almost no airtime. The obvious one is defensive. Your block arrives sooner, you attest on the right head, you stop leaking rewards you already earned. The other one runs in the opposite direction. Every proposer faces the same trade at the top of a slot: publish early and safe, or hold on a little longer for a more valuable block. Holding on is worth real money, because the longer a builder works, the more it can pack in. Holding on is also exactly what gets you orphaned if the network cannot carry your block across the planet in time. Faster propagation moves that line. When delivery takes a fraction of the time, you can afford to decide later, and deciding later is where the extra revenue lives. Which is why latency is money is not just a phrase borrowed from trading desks. Onchain it pays twice: once for not missing a deadline, once for buying you permission to wait. Médard made that second point in an interview this week. It's the half of @get_optimum's case that builders will understand before anyone else does. @discordflash
