為什么我根據自己建立的私有鏈創建令牌后,以太坊賬戶的余額仍為零?

[英]Why is the balance of the ethereum account still zero after I create a token based on the private chain I built?

我使用以太坊官方網站上提供的合同代碼,[創建自己的cryto-currency] [1]在geth控制台中運行的私有鏈上創建高級令牌。 geth的版本為1.5.5,solc的版本為0.4.8。

我的步驟是:

1.初始化我的geth: geth初始化 genesis.json,然后geth --networkid 42 --nodiscover --maxpeers 0控制台

2.檢查編譯器:*** eth.getCompilers()***返回:實體

3.我使用在線編譯網站[Remix] [2]給了我相關的abi和代碼來直接部署我的合同。

我輸入:

(1) abi = [{“ constant”:false,“ inputs”:[{“ name”:“ newSellPrice”,“ type”:“ uint256”},……太長,無法復制結果;

(2)然后創建合同: multipliyContract = web3.eth.contract(abi)

(3) 乘法= multipliContract.new(10000,“ AKING”,2,“ AK”,0xf32200730fdaca83f18171015c0be2a6342d46c4,{來自:primaryAddress,數據:0x + code})

第一個參數表示初始供應,第二個參數表示令牌的名稱,第三個參數表示小數單位,第四個參數是可以初始提供令牌的地址。

4.檢查我的合同是否已經部署:

我輸入: txpool.status

然后我得到:等待:1

5.我開始開采合同:

輸入: miner.start()miner.stop()

然后我輸入: eth.getBlock(5319)

我發現了那筆交易。

6.與我的合同互動:

輸入: MyContract = eth.contract(abi)

然后: myContract = MyContract.at(multiply.address)

  1. 開始采礦一段時間。

整個過程進展順利,但是當我輸入

myContract.balanceOf(0xf32200730fdaca83f18171015c0be2a6342d46c4) (地址是eth.account [0],也是擁有我創建的令牌的地址。 我還嘗試了其他一些地址,它們都歸零。 我還嘗試了其他一些表達式,例如myContract.balanceOf(eth.accounts [0],{來自:eth.accounts [0]})myContract.balanceOf.sendTransaction(eth.accounts [0],{來自:eth.accounts [0]})

如果我使用: eth.getBalance(eth.accounts [0]),它將僅返回我賬戶中的以太幣 ,這不是我想要看到的。

那么,我的過程有什么問題嗎?或者有什么重要的事情值得錯過?有什么意義?

整個代碼如下:

將此myContract.balanceOf(0xf32200730fdaca83f18171015c0be2a6342d46c4)更改為此myContract.balanceOf("0xf32200730fdaca83f18171015c0be2a6342d46c4")
