Most gas models in crypto are a tax on using the thing you already paid for. You bought the token. Now spend more of it every time you touch the network. Midnight designed around that problem, and I keep coming back to how quietly clever the solution is.
Holding NIGHT generates DUST a shielded, non-transferable resource that powers transactions and private smart contract execution. You don't spend NIGHT to use the network. You hold it, it produces fuel, the fuel gets consumed, and then it regenerates. Developers can delegate DUST to power applications for their users without transferring the underlying NIGHT meaning an enterprise deploying on Midnight can absorb every transaction cost on behalf of their users entirely. The end user never touches a token. They just use the application.
That's not a marketing feature. That's the design decision that makes regulated industries actually willing to build here. A healthcare platform can't tell patients to buy gas tokens before verifying their insurance. A compliance tool can't require its corporate clients to manage a wallet balance alongside their legal obligations.
I still don't know if the applications show up. But the architecture for when they do is genuinely thought through.
