Until now we have got a fair idea on ethereum smart contracts, Smart Contracts are like real world contract in digital form which has legal as well financial implications.

We have also seen that there is always a cost associated when we deploy or transact on smart contract on live network and that fee should be paid by the user. While you will proceed to plan your development on ethereum, we should explore the other test net available for development purpose.

Ethereum Networks:

Live Network: This is the network used for production activities, all the value exchanged over this network are the real and does have a legal as well financial implications. Every network has a unique ID

Network ID for Live net is equal to 1.

Test Networks:
Ideal for development and testing purpose, ether spend here does not hold the actual value. Majorly used two test net are

ID = 3 (Ropsten): By default testnet refers to Ropsten testnet, supports consensus POW, we can carry out mining on Ropsten network

ID = 4 (Rinkeby): Public test network, supports private block chain consensus POA and due to that we can’t carry out mining on Rinkeby network

Private Ethereum network:

You can build a private network (permissioned network) using Ethereum block chain. Many organizations prefer to use private semi private network (consortium chain) due to data privacy concerns. Such networks sometimes also referred as consortium chain where pre-approved authority nodes on the network for transaction validation, it follows POA~ Proof of Authority consensus for transaction validation, Protocol used for implementing POA is known as CLIQUE. There is no concept of mining on private network instead the pre authorized nodes validate the blocks and add to block chain.
For private network ID of the network is assigned by the developer of the network.
