Which Ethereum Testnet To Use?

An Ethereum testnet is used by developers to test and run their dApps or contracts on the Ethereum network, before making them live on the original Ethereum chain. We will explore different testnets available on Ethereum.

Be careful when connecting to a testnet, as any address or token working on Ethereum will also work on the testnet.
If you don’t pay attention, you can accidentally send tokens or real Ethereum to a testnet.

Ganache & Infura

Ganache is your personal Ethereum blockchain, which is useful for testing and interaction with your contracts during development.
Infura by ConsenSys is an infrastructure that provides access to several Ethereum networks and IPFS.
Infura can be used to distribute smart contracts to the mainnet, as well as Ropsten, Rinkeby, and Kovan.

Ropsten supports both Geth and Parity, two types of Ethereum node software implementation, allowing developers to create two different angles of the project they are testing.

Infura allows you to send signed Ethereum transactions over the Internet to the Rinkeby testnet, and the implementation of contracts is just another type of Ethereum transaction.
You can also use your Ethereum address to get a list of all the transactions you have sent.
Ethereum’s addresses can contain very, very large amounts of money and their private keys must be kept in place.

Geth is a CLI ( CLI ) command line interface that communicates with the Ethereum and acts as a connection between your computer, hardware, and other Ethereum or networked computers.
Mining in the real or Main Ethereum blockchain is quite difficult and requires specialized equipment such as special GPUs.

In principle, many languages can be compiled up to the byte code used by the Ethereum VM, but in practice, almost all intelligent contracts are written in the “Ethereum – indigenous” language called Solidity.
Reminder: “the web frame called a Node” and “an ethereal Node” are two completely different uses of the same word.

If you want additional security by running two different implementations in parallel or if you are serious about extracting the GPU, then the C ++ “ETH” client is for you.
