Before this chapter, I have to say that running in the ether Dapp and our ordinary app is a great difference, that is, the persistence of intelligent protocol , we compile the program will be permanent, immutable existence on the Ethernet, there is no like our centralized system on the possibility of continuous version of the iteration.
