Yes, it's the basic idea of all the blockchain based implementations. The challenge here is you have to seal the data packet first, make a layer 2 commitment that has some kind of cryptographic binding to the data. Then you have to have a mechanism to atomically open the data while paying the contract. This can be done with some homomorphic properties of some cryptographic primitives but the computational cost is currently very high.
