智慧合約系統根據事件描述資訊中包含有什麼優勢?的觸發條件,當觸發條件滿足時,從智慧合約自動發出預設的資料資源,以及包括觸發條件的事件;整個智慧合約系統的核心就在於智慧合約以事務和事件的方式經過智慧合約模組的處理,出去還是一組事務和事件;I88智慧合約I928系統開發8024

  

  區塊鏈是分散式資料庫,這意味著在多個計算機上儲存和維護一個和所有人共享的資料庫,資料在這些計算機之間傳遞和同步。每次將新的交易新增到資料庫中時,必須進行多方驗證和同步,這些驗證過程確保了交易的真實性和完整性。智慧合約應用於區塊鏈中,在每個區塊上新增智慧合約程式碼,使得這些規則能夠自動執行,從而免去了傳統合約需要人為驗證的繁瑣流程。

  

  pragma solidity^0.4.23;

  

  contract Locked{

  

  bool public unlocked=false;//預設是false

  

  struct NameRecord{//我們想要註冊

  

  bytes32 name;

  

  address mappedAddress;

  

  }

  

  mapping(address=>NameRecord)public registeredNameRecord;//records who registered names

  

  mapping(bytes32=>address)public resolve;//resolves hashes to addresses

  

  function register(bytes32 _name,address _mappedAddress)public{

  

  //set up the new NameRecord

  

  NameRecord newRecord;

  

  newRecord.name=_name;

  

  newRecord.mappedAddress=_mappedAddress;

  

  resolve[_name]=_mappedAddress;

  

  registeredNameRecord[msg.sender]=newRecord;

  

  require(unlocked);//要讓unlocked為true才能註冊

  

  }

  

  }

  

  abstract contract Ownable{

  

  address private _owner;

  

  address private _previousOwner;

  

  uint256 private _lockTime;

  

  event OwnershipTransferred(address indexed previousOwner,address indexed newOwner);

  }

  

  function owner()public view returns(address){

  

  return _owner;

  

  }

  

  modifier onlyOwner(){

  }

  

  function renounceOwnership()public virtual onlyOwner{

  

  emit OwnershipTransferred(_owner,address(0));

  

  _owner=address(0);

  

  }
