What are decentralized APPlications?

Unlike traditional APPs that run back-end code on a centralized server, APP's back-end code runs on the blockchain. Of course, DAPP front-end code and UI can be developed in any language and deployed on any server to interact with back-end logic.

Because the back-end logic is placed in a highly secure, tamper proof smart contract, DAPP enjoys many advantages that traditional Web2 systems cannot obtain:

Because DAPP can carry back-end logic through highly secure and tamper proof smart contracts, DAPP has many advantages that Web2 systems do not have:

No downtime

More privacy

Anti manipulation

Execute logic in a minimal trust environment

However, these advantages also bring corresponding disadvantages. Because the code is deployed on the blockchain, these logic cannot be modified by default, so the maintenance of DAPP is difficult. In addition, because the code runs in a distributed network rather than a centralized server, the performance will be low. In addition, because users need to have a Web3 wallet and have enough encrypted assets to pay the service charge, the user experience will also decline.
