3 Compile and run your first smart contract against local private node - Ethereum from scratch Matt Thomas

Welcome to episode 3 of my series on Ethereum for beginners - hands on tutorials that you can follow step by step to gradually build awareness of the protocol.

In this video I describe how to install the local copy of the browser-solidity compiler so you can compile and deploy smart contracts against your own private Ethereum networks.

Steps/main commands below:


*******
Go to this link
https://github.com/ethereum/browser-s...
**********
Download the zip file and copy/extract to local folder
*************
Open index.html
****************
Paste this into the window
pragma solidity ^0.4.0;
contract greeter { string greeting; function greeter(string _greeting) public { greeting = _greeting; } function greet() constant returns (string){ return greeting; }




function calculateProof(string document) constant returns (bytes32) {
return sha256(document);
}
}
******************
REMEMBER TO RECONNECT THE BROWSER TO THE Web3Provider WHENEVER YOU RESTART
****************
Choose the web3.provider and type http://localhost:8545
***************
Make sure geth is started
geth --datadir "(dir)" --nodiscover --rpc --rpcport "8545" --rpccorsdomain "*" console 2 > console.log

Add the rpc flags above - they are all necessary (have removed all other flags to hide noise)
****************
Ensure the account is unlocked
personal.unlockAccount(eth.accounts[0])
*****************
