What is Goerli Testnet?

The Goerli test net is a test network for the Ethereum blockchain, designed to be a “proof of concept” for the Ethereum 2.0 upgrade. It was launched in January 2019 by the Ethereum research team, with the main purpose of providing a testing environment for developers and researchers to experiment with new features and improvements before they are implemented on the main Ethereum network. The Goerli test net is considered a more reliable and efficient test network as compared to other Ethereum test networks like Rinkeby, Kovan, and Ropsten.
One of the main uses of the Goerli test net is for developers to test their code and applications in a real-world environment, without having to worry about the cost and complexity of deploying on the main Ethereum network. This is particularly useful for testing complex smart contract deployments and dApps, as well as for experimenting with new consensus algorithms and other features that are being proposed for Ethereum 2.0. The Goerli test net can also be used to test and experiment with new scaling solutions like sharding, which is one of the key features of Ethereum 2.0.
