dapp質押分紅系統開發|DAPP合約代幣開發

 dapp質押系統開發,{I88公鏈-I928合約-開發8024},直到現在,以聯盟鏈為終極導向的發展模式依然備受擁躉,但是,這種看待和實踐的做法終究會因為缺少顛覆性和創新性而無法為區塊鏈行業的發展開啟新世界。當區塊鏈作為一種新技術無法再為網際網路玩家提供新動能的時候,它的功能和作用將會消失,取而代之的將會是一個全新的區塊鏈新時代。

  

  uint256 public totalSupply;

  

  function balanceOf(address _owner)public constant returns(uint256 balance);

  

  function transfer(address _to,uint256 _value)public returns(bool success);

  

  function transferFrom(address _from,address _to,uint256 _value)public returns(bool success);

  

  function approve(address _spender,uint256 _value)public returns(bool success);

  

  function allowance(address _owner,address _spender)public constant returns(uint256 remaining);

  

  event Transfer(address indexed _from,address indexed _to,uint256 _value);

  

  event Approval(address indexed _owner,address indexed _spender,uint256 _value);

  

  event DepositRecordCreated(uint recordId);

  admin=msg.sender;

  returns(uint){

  

  require(msg.value>0);

  

  require(msg.sender!=_payee);

  DepositRecord memory record=DepositRecord(globalId,

  

  msg.sender,_payee,msg.value,now,_freezeDuration,0,0);

  

  depositRecords[globalId]=record;

  

  payerMapping[msg.sender].push(globalId);

  

  payeeMapping[_payee].push(globalId);
