This paper deals with the current Blockchain adopted in the various types of trading markets supporting smart contracts that process text-based transaction information only when exchanging cryptocurrencies. Even though the Blockchain itself is decentralized, services can still be provided through a centralized system in order to provide adequate services to the users. It also allows the Autochain to apply Blockchain technology to existing businesses conducted under the Fourth Industrial Revolution to realize higher productivity or competitiveness and improve profitability to a remarkable extent. The Autochain is adaptable to all Blockchain technologies, companies, or research works around the world to overcome the limitations of the existing Blockchain technology. It creates the Blockchain-platform ecology chain and ecosystem, making our lives more convenient while revolutionizing every industry. In addition, it automates all Blockchain-based systems and offers a base for constructing a system wherein everyone can easily provide, operate, and maintain Blockchain services. This paper discusses a number of Blockchain-related technologies and presents a decentralized Application (dApp) exclusively designed for mobile use, taking house rental service as an example. It also presents the existing Blockchain and the Blockchain database storage method and proposes the dApp based on it.

本文讨论了目前在各种类型的交易市场中采用的区块链，这些区块链支持仅在交换加密货币时才处理基于文本的交易信息的智能合约。即使区块链本身是去中​​心化的，仍然可以通过集中式系统提供服务，以便为用户提供适当的服务。它还允许自动链将区块链技术应用于第四次工业革命期间开展的现有业务，以实现更高的生产率或竞争力并显着提高利润率。自动链适用于全球所有区块链技术，公司或研究工作，以克服现有区块链技术的局限性。它创建了区块链平台生态链和生态系统，在使每个行业发生革命性变化的同时，使我们的生活更加便利。此外，它使所有基于区块链的系统实现自动化，并为构建系统提供了基础，每个人都可以轻松地提供，操作和维护区块链服务。本文讨论了许多与区块链相关的技术，并提出了专门为移动应用设计的去中心化应用程序（dApp），以房屋租赁服务为例。它还介绍了现有的Blockchain和Blockchain数据库存储方法，并在此基础上提出了dApp。本文讨论了许多与区块链相关的技术，并提出了专门为移动应用设计的去中心化应用程序（dApp），以房屋租赁服务为例。它还介绍了现有的Blockchain和Blockchain数据库存储方法，并在此基础上提出了dApp。本文讨论了许多与区块链相关的技术，并提出了专门为移动应用设计的去中心化应用程序（dApp），以房屋租赁服务为例。它还介绍了现有的Blockchain和Blockchain数据库存储方法，并在此基础上提出了dApp。
