Ganache
The most popular local Ethereum blockchain is Ganache. You can use Ganache to develop, deploy, and test in a safe and deterministic environment. Ganache can be used from the command line, programmatically via Node.js, or in the browser. In this module, we'll use the command line version so that we can interact with it directly from the terminal.
To install Ganache in your project, go to the terminal. Right-click and then select New Terminal. When the new terminal window opens, run:
npm install ganache --global
After Ganache is installed, run:
ganache
Notice that the blockchain has 10 generated accounts, and each receives 100 test ether to use. Each account also has a corresponding private key. Every account also has a mnemonic. A mnemonic is a unique 12-word phrase that provides access to the wallet and allows transactions to be made from the account.
The output also displays the blockchain's address. We'll use this address to connect to the blockchain. By default, the address is 127.0.0.1:8545.
