Nasdaq requires that every message is included, and that all messages are treated the same. The way that priority fees work is that any txs with a priority fee lower than the floor inclusion price in the block doesn’t get included. So the comparison to Nasdaq that matters is scheduler throughput and latency, not block tps or consensus latency. You can have 10 second blocks with 1000 tps, and a scheduler on the block producer that can reliably tell the trader that their tx is included in microseconds. If the floor priority fee is < spread / K for a pretty small K, then including additional messages is not going to improve spreads. Solana already achieved this. The floor inclusion price is a fraction of a basis point, which means that additional dropped messages have an economic value of less than a basis point. Dropping them vs including them has nearly zero marginal difference.(toly 🇺🇸)
