What is a testnet?
You may have come across the terms “mainnet” and “testnet” in the blockchain world. So, let’s break it down.
A mainnet is a “live,” basic version of a blockchain. For example, if you go to the OpenSea marketplace right now and buy NFTs, you will have interacted with the mainnet of the Ethereum network.
On a testnet, there is also cryptocurrency, which is largely similar the real one: It can be stored in a wallet, received, and sent. The difference is that testnet coins have no value. It’s like money from Monopoly: If you accidentally lose it, nothing bad will happen.
In general, on a testnet, developers test and polish their ideas, whereas on a mainnet, they present them to all users.
