Local Node

An Ethereum node provides different functionalities :

  1. To be connected to other nodes and exchange blocks and transactions
  2. To verify each transaction by running the Ethereum Virtual Machine
  3. To provide an API to interact with the node
  4. To provide a basic wallet to sign transactions and collect fees when mining

For now you will simply learn to launch a local node.

Instructions

Launch a local test node. You can use any client (geth, openEthereum...), but I recommend javascript test nodes hardhat and ganache-cli.

hardhat node

npm i hardhat
npx hardhat node

ganache

npm i ganache-cli
npx ganache-cli

You can also use ganache ("non cli") that provides a nice graphical interface. For compatibility, change the listening port to 8545 in the settings

Noticeably, local javascript nodes are not connected to any network and provide already 10 account populated with test ether.
