What is a distributed app (DAPP)?
DAPP (distributed application) is like a smartphone or laptop application, and has a unique feature that uses blockchain technology to prevent user data from reaching a major IT company. 。 Just as the cryptocurrent assets (virtual currency) are distributed money, Dapp is a distributed, non -centralized app. In the blockchain, many computers participating in the network, so -called "node", save all data copies. And the node is not the creator of the DAPP, but by the user. There are various types of DAPPs, such as social networks (SNS), games, entertainment, and productivity improvement tools. But at present, many DAPPs are being developed as a tool for users to access the Defi (distributed finance) service. Defi (distributed finance) is gaining popularity as the white paper of Ethereum Blockchain categorizes DAPP into "finance," "quasi -finance," and "others." The Ethereum blockchain is currently an overwhelming share as a DAPP base blockchain. At the beginning of the start, one of the main purposes of Ethereum was to make DAPP easier. For users, the fact that application developers cannot control the usage status (at least in the past) will lead to a sense of security. For example, the developer of the distributed SNS application does not have the power to delete posts or eliminate users. Furthermore, since the app operates autonomously (= leaving the developer), user data cannot be sold to someone.
Why is this possible? That's because "smart contracts" are used. The program deployed on the blockchain executes the rules (contract) set in advance without human resources. For example, if a user deposits a sufficient amount of collateral in the blockchain, it is programmed to make a loan. Dapp is generally open source, and anyone can browse and use the program. DAO (autonomous distributed tissue) can be considered as a type of DAPP, and is trying to achieve the functions of conventional organizations without needing executives and up and down structures by combining smart contracts in a complicated manner. DAO decisions are made through a voting system that has a large voting right for members with many tokens. This is based on the idea that people who have invested a lot of funds in DAO are more likely to participate in sincerity for the interests of the organization. | Translation: coindesk Japan | edit: Takayuki Masuda | Image: | Original text: What is a dapps explained
