安裝Go-ethereum (geth)
使用cmd創建資料夾並移動到該目錄
在該目錄下新增檔案genesis.json

//初始化並建立一個新的節點
geth --datadir data init genesis.json
//啟動節點
geth --datadir data --networkid 123456 --rpc --rpccorsdomain "*" console
//建立帳戶
personal.newAccount()
//開始挖礦
miner.start()
//停止挖礦
miner.stop()
//查看帳戶[0]餘額
eth.getBalance(eth.accounts[0])
（置頂圖）使用Remix - Solidity IDE撰寫智慧合約！
- environment選擇Web3 Provider(連接到自身node)
- 帳戶有餘額才能使用
//解鎖帳戶
personal.unlockAccount(eth.accounts[0])
//按 Create（cmd產生的contract待會用到）
//查看Detail內的ABI並複製
/*我的複製不能用，求解 ( ´•̥̥̥ω•̥̥̥` )
只好自己透過上面的資訊自行編輯
用成以下格式宣告於cmd中*/

var address = "0x44141F94a85C08cF14ac05f8b0483e5613a65B60"
//定義vote合約
var vote = eth.contract(abi).at(address)
//定義defaultAccount
eth.defaultAccount = eth.accounts[0]
//投票（1號或2號）
vote.voteCandidate(1)
//要先讓他挖一下才會有結果
miner.start()
//停止探勘
miner.stop()
//查看投票結果
vote.getResult()
