Artificial intelligence technology is one of the core technologies in the era of intelligent industry.AI technology includes machine learning,deep learning,natural language processing,computer vision,etc.The application of these technologies enables the machine to learn,understand and judge independently,and can help industrial enterprises achieve automated,intelligent and efficient production and management.

　　智能合約(Smart contract)是依托計算機在網(wǎng)絡(luò)空間運行的合約，它以信息化方式傳播、驗證或執(zhí)行合同，由計算機讀取、執(zhí)行，具備自助的特點。而區(qū)塊鏈的去中心化，數(shù)據(jù)的防篡改，決定了智能合約更加適合于在區(qū)塊鏈上來實現(xiàn)

　　#dev User specifies exact input(msg.value).

　　#dev User cannot specify minimum output or deadline.
