The general corporate network will be divided into the intranet (wired) and the external network (wireless), and the network access restrictions rules, resulting in some applications can not be used, this situation we want to be connected to the intranet, but also hope that some programs can access the extranet. What do we do? The following configuration can be u
The network cable is already inseparable from our life. Because we often use the network cable, we need the network cable to access the Internet. Therefore, we need to learn how to make the network cable so that we can better control our life in Russia,
Okay. Let's just talk about the
First, the production network
Advantages:
1, globalized, deployed in the Internet environment
2, the implementation of the code of the smart contract, block calls, can be clearly seen
3. A smart contract deployed in a production environment that can be called by any application in the world
Disadvantages:
1, any contract execution will consume the real etheric currency, that is, real cash, not suitable for development, commissioning and testing
