Hi. I wonder is that anyway to assure people pay by instalments in blockchain ?

example:
I buy a car with a instalments plan if i pay in:

- Fiat currencies: I have to have my credit score, my indentity document, .... to assure my payment. We all known how it work.

- Crypto currencies: What will make sure that I will pay monthly, daily,...? Anyway to make pledge or collateral with smart control ?
