Geth_Ganache

This is a basic set up of Geth to create 10 accounts preloaded with 100 ETH to use for whatever your wish desires (withib your private network of course)

Dependencies

Geth Version: 1.8.3-unstable

You must first have Geth. If you do not yet, you can download it here.

Getting Started

  • you must clone this repo
  • open up a terminal
  • cd into /path/to/directory/sh/
  • run the script ./start.sh
  • follow the instructions in the command line
  • more info here

What this project does (in a nutshell)

  • initiate Geth using network id: 555555 (can change this is the Genesis.json file)
  • starts geth with 10 accounts that are all preloaded with 100 ETH
  • all accounts are pre-unlocked upon starting geth (important if you wish to have them run transactions)

What you can do with it (basic)

  • This project was to emulate Truffle's Ganache but in the Geth environment
  • You can essentially do what Ganache can do using this (without the nice gooey)
  • connect a Truffle project to deploy a smart contract and interact with the 10 pre-loaded accounts
  • run web3.js functions using these accounts

Some somewhat important functions (inside geth console)

miner.start()
  • this will only start mining for the primary account (0x9d840872DDef20df865FAdD87E71a04DffDC7c0C)
web3.fromWei(eth.getBalance("0x9d840872DDef20df865FAdD87E71a04DffDC7c0C"), "ether")
  • this will show the account's balance in ETH (change the account address if you wish to see another account's balance)
personal.listWallets
  • this will list all accounts, show their addresses, url, and status (LOCKED/UNLOCKED)
personal.sendTransaction({from:'0x9d840872DDef20df865FAdD87E71a04DffDC7c0C',to:'0xcdd3516d2013251e098caf1200e0823c673513cc', value: 1000000000000000000},"password")
  • this will send 1 ETH from account 'from' to account 'to'
  • this will only execute if you have miner.start()
