Can I perform transaction from different server - Blockchain

Question

Ethereum blockchain is decentralized and we have 4-5 servers which are mainnet,rinkeby, Kovan,ropsten and local Server.

If I create a Web App on Rinkeby so can other Server Account holder users can access that website and perform transactions(from another server) on it or not?

For Example, if I create a voting app on the rinkeby server, can I vote someone using the mainnet server?

Answer 1

You need to understand the differences between test Ethereum networks, public Ethereum networks and private Ethereum networks first. Read more about Ethereum public, test and private networks here. Also, each test network has its own compatibility with different Ethereum clients.

So, you are supposed to test your code using Ethereum private networks or test networks like Rinkeby and then deploy it to Mainnet.
