Move是第一個解決這個問題的智能合約語言(通過結構體,move_to/borrow_globol,abilities等等)  ```move= fun buy(c: Coin): CarTitle{} fun register(c: &CarTitle, fee: Coin): CarRegistration{} ``` ==Move可以在不丟失完整性的情況下跨越信任邊界== Move >>> Java(專注在完成單一功能)?! Solidity >>> C(完成功能的前提下瞭解底層邏輯)!? ==數字資產不能隨便被 複製,要透過嚴密的轉移。ex. borrow_global_mut, move_to等==  <h3>Move生命週期</h3>  ==sources==是本地的編碼,透過佈署至Move的公鏈上,透過address publish成為Global Storage。 ==TX==是資源調用的模塊,透過VM可以Read或Write等功能改變Global Storage的資源。 <h3>Move編碼結構</h3>  <h3>Move字節碼教驗</h3>  <h3>字節碼執行</h3>   老師麥克風出現問題今天上課到一半就暫停了!!
