 智慧合約產生價值的最基本前提是有一個強有力的底層介質用於儲存,讓其不可被物理破壞。

  

  然而,智慧合約的本體是一份程式碼,非常容易被篡改,如何為其提供強力的儲存介質就成了問題。這正好是區塊鏈擅長解決的——透過比特幣的實踐,證明瞭區塊鏈可以在分散式環境下讓電子記錄不可被篡改。

  

  與此同時,智慧合約也在反哺著區塊鏈,它極大地擴充套件了區塊鏈的業務場景。I88智慧合約I928系統開發8024

  

  The function then does some sanity checks.First,it checks that the destination address isn’t a null address.In other words,tokens must not be sent into oblivion.Next,it checks if the sender is even allowed to send this many tokens by comparing their balance(balances[msg.sender])with the value passed in for sending.If any of these checks fail,the function will reject the transaction and fail.It will refund any tokens sent,but the gas spent on executing the function up until that point will have been spent.
