SolaRoad智慧合約持幣生息系統開發詳情方案

 智慧合約的不可逆性是指一旦執行,合同就會被寫入區塊鏈,無法更改或刪除。智慧合約利用更高的加密技術提高了資料安全性和可靠性,資料不易被修改、破壞和篡改。

  

  一旦智慧合約啟動,將無法撤銷、更改或取消合同,同時合同相關的所有資料也將被儲存。

  

  此外,智慧合約的不可逆性可以防止資訊篡改、資料刪除或其他可疑活動的發生,從而增強了資訊保安和資料保護性。

  

  The following variables are

  

  OPTIONAL vanities.One does not have to include them.

  

  They allow one to customise the

  

  token contract&in no way influences the core functionality.

  

  Some wallets/interfaces might

  

  not even bother to look at this information.

  

  library VectorSum{

  

  //This function is less efficient because the optimizer currently fails to

  

  //remove the bounds checks in array access.

  

  function sumSolidity(uint[]_data)returns(uint o_sum){

  

  for(uint i=0;i<_data.length;++i)

  

  o_sum+=_data<i>;

  

  }

  

  //We know that we only access the array in bounds,so we can avoid the check.

  

  //0x20 needs to be added to an array because the first slot contains the

  

  //array length.

  

  function sumAsm(uint[]_data)returns(uint o_sum){

  

  for(uint i=0;i<_data.length;++i){

  

  assembly{

  

  o_sum:=mload(add(add(_data,0x20),mul(i,0x20)))

  

  }

  

  }

  

  }

  

  function freeze(uint256 _value)public returns(bool success){

  

  if(balanceOf[msg.sender]<_value)revert();//Check if the sender has enough

  

  if(_value<=0)revert();

  

  balanceOf[msg.sender]=SafeMath.safeSub(balanceOf[msg.sender],_value);//Subtract from the sender

  

  freezeOf[msg.sender]=SafeMath.safeAdd(freezeOf[msg.sender],_value);//Updates totalSupply

  

  emit Freeze(msg.sender,_value);

  

  return true;

  

  }
