　　什麼是DApp?DApp應用需要滿足那些條件?DApp是一種網際網路應用程式，與傳統的App最大的區別是：DApp執行在去中心化的網路上，也就是區塊鏈網路中。區塊鏈相對於DApp來說是應用執行的底層環境。

　　Blockchain can run code.Although the initial blockchain was used for simple programs,mainly token transactions,technological advancements allowed it to execute more complex transactions and identify well-developed programming languages.

　　Because these programs run on the blockchain,their characteristics are different from other software.Firstly,the program itself is recorded on the blockchain,thus possessing the permanence and non auditing properties of the blockchain;Secondly,the program can control blockchain assets,such as storing and transmitting cryptocurrencies;Thirdly,the program is executed by blockchain.This means that no one can follow the pre written content and interfere with its operation.

　　DApp是（Decentralized Application）的縮寫，開發方案威：MrsFu123,中文直譯為去中心化應用，也可以理解為分散式應用。DApp基於區塊鏈，主要出現在以太坊、EOS等分散式平臺或網路上，不依賴任何中心伺服器，實現去中心化的目的。與傳統的APP不同，DApp堅決強調去中心化，必須執行在分散式的作業系統，而不能工作在iOS及Android這些傳統平臺上。儘管不依靠任何中心節點，但DApp卻離不開智慧合約
