Plasma doesn’t win as the fastest chain. Plasma wins as the most certain chain.
Speed is pointless for payments unless you don’t still need to check, refresh, and re-send. What Plasma changes is the psychology of money flow. With PlasmaBFT and the ability for gasless stablecoin transactions, once you send money, it is literally just done. No waiting for blocks. No need for wondering if it will fail. No surprise fees.
That kind of confidence will likely change people’s behavior when it comes to using stablecoins. They will no longer behave as traders but will behave as users instead. You pay, you move, and you settle, just like real money.
Most of them are trying to maximize throughput. Settlement is where plasma is focusing on creating trust, which will ultimately unlock general crypto payments.
