 區塊鏈透過token來標記價值,所有資產都能夠被極簡易的在區塊鏈上表達,資產交易所的構造和邊際成本趨於零。毛球科技技術研究部認為,這是區塊鏈的核心技術之一,它所帶來的是在零邊際成本場景下,流動性的爆發。

  

  只有流動性才是區塊鏈價值的傳導機制,188智慧合約1928系統開發8024

  

  貨幣的流動性通俗來講是指貨幣在流透過程中不發生損失的情況下迅速變現的能力。而隨著資訊化程式加劇,要求貨幣更具有簡便、快速的交易,紙幣現在流動性的變現形式已經遠低於電子貨幣。

  if(msg.sender!=sender)return;//直接return
  
  _;

  balances[receiver]+=amount;

  function send(address receiver,uint amount)public{
  
  if(balances[msg.sender]<amount)return;
  
  balances[msg.sender]-=amount;

  

  balances[receiver]+=amount;

  

  emit Sent(msg.sender,receiver,amount);

  

  }
