I ordered a coffee machine on JD yesterday, and it was delivered to my doorstep the next morning.
Free shipping, no worries about logistics.
When I was unpacking the delivery, I suddenly realized an issue:
This delivery truck that brought the coffee machine, I don't care how much fuel it consumed while speeding or if it took the toll highway, and I don't need to know.
I only paid for the coffee machine, the rest of the logistics cost was handled by JD in the background.
This made me reevaluate the design philosophy of @Plasma .
The current public chain market is like an extremely primitive logistics system.
You want to transfer some USDT to a friend (to buy a coffee machine), but the system forces you to buy some ETH or TRX first (to fuel the truck). If there's not enough fuel, your goods will rot in the warehouse.
This is simply anti-human.
You're completely wrong.
In the Paymaster model of Plasma, users are like the ones receiving packages.
You don't need to hold the mainnet coin or understand Gas Price. Just transfer your stablecoin, and the underlying miners and nodes will automatically handle all friction costs in the background like Amazon's logistics fleet.
Some may ask, what is the value of $XPL ? Is it useless?
On the contrary.
Just like JD's logistics, the faster it runs and the larger the volume, the more terrifying its consumption of fuel and maintenance becomes.
In the Plasma network, every seemingly 'free' or 'smooth' stablecoin payment is backed by a state change on the chain.
Although users may not feel it, the underlying nodes are running wildly, and the Paymaster is purchasing and consuming $XPL in real-time to pay network fees.
This is a more advanced form of 'burning'.
Previous public chains charged users tolls and earned 'spare change';
Plasma packages tolls into a commercial closed loop, earning a 'system maintenance fee' from the flow of the entire payment ecosystem.
When thousands of RWA assets and cross-border payments rush on-chain like 'free shipping', the scarcity of $XPL, as the underlying fuel, is not shouted out but is 'run out' by this massive logistics volume.
If you understand this logic, you will understand the second half of Web3 payments.
