Intro to Ethereum and Sample Solidity Contracts
This repo is meant to be a guide to help developers get up and running with solidity contracts.
Useful javascript console commands:
personal.newAccount()
personal.unlockAccount(eth.accounts[0])
eth.accounts
web3.fromWei(eth.getBalance(eth.accounts[0]))
eth.sendTransaction({from:eth.accounts[0], to:"0x78cceb41fbc9a3db8746ead04d2db81b37ae9617",value:web3.toWei(1)})
personal.unlockAccount(eth.accounts[0])
admin.peers
admin.nodeInfo
eth.getTransaction(<tx_hash>)
Guest List Contract Helpers:
var guestlistContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"_name","type":"string"}],"name":"signList","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"guests","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"printLastGuest","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"guestNumber","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"","type":"uint256"}],"name":"guestList","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"inputs":[],"type":"constructor"}]);
var guestlist = guestlistContract.at("0x0de4f2933334333253642fcfa855d71f37e7b83a");
guestlist.signList("Your_Name",{from:eth.accounts[0],gas:300000})
guestlist.printLastGuest.call();
guestlist.guests(eth.accounts[0]);
