Geth Local Setup

This repository provides a few utilities to setup a local private ethereum chain as well as a few javascript functions that can be used to interact with your local chain.

The cryptodollar contracts are deployed on the cryptofiat-a branch. The addresses are shown in the following section.

On the dex branch, the contracts corresponding to the proof decentralized exchange have been deployed. The addresses are shown in a following section.

Requirements :

  • OSX or Linux
  • Geth (1.8.2-stable)
  • Solidity

Features

This local private chain comes with the following setup:

  • Byzantium enabled
  • High Block gas limit to simulate current network condition (it seems as though the gas limit automatically comes down after after a while)
  • Websocket API

Setup

To use the front-end test application for the cryptofiat contract, first create a private blockchain.

./create.sh

Start a node on the private blockchain

./start.sh

On a different terminal instance attach a geth process to the current to your running node

geth attach /path/to/geth.ipc

(Note: The IPC path is displayed on the logs when starting the node)

In the console, you can now download javascript utility functions and use them to manage your private chain.

loadScript('setup-accounts.js')
loadScript('unlock-accounts.js')
loadScript('allocate-ether.js')

You can start mining or stop mining with the following commands:

miner.start(4)
miner.stop()

After mining a sufficient amount of ether, you can allocate ether in order to be able to deploy the Oraclize contract (see below).

allocateEther()

Occasionally you will need to unlock accounts

unlockAccounts()

Testing the CryptoDollar contracts

After setting up your private chain correctly, instantiate the testnet oraclize service. From the ProofCryptoFiat folder:

cd ethereum-bridge
npm install ethereum-bridge
node bridge -H localhost:8545 -a 1 --dev --update-ds

Write down the Oraclize Address Resolver Address (OAR) and insert it in the CryptoFiatHub contract. Compile and migrate the CryptoFiat contracts on the development_geth network.

truffle compile --all
truffle migrate --reset --network development_geth

NetworkID

The networkID of this private network is 8888
