What are the advantages and features of blockchain
Smart contract refers to electronic contract, digital contract and intelligent contract. Generally speaking, the contract is written into a program in code. Once this code is written, it will be made public, and can not be modified or tampered with
If the conditions change, such as default or contract expiration, the smart contract will be triggered automatically.
DAPP = smart contract + app. Generally, DAPP is defined as an application running on a distributed network, in which the information of participants is safely protected and decentralized operation is carried out through network nodes. Generally speaking, different
DAPP will adopt different underlying platforms and consensus mechanisms, or issue tokens by itself.
An application that meets the following three conditions can be considered as a DAPP (distributed application):
1. Running on distributed network;
2. Participants' information is stored safely and their privacy is well protected;
3. Decentralized operation through network nodes.
Features of blockchain DAPP program development
The development of blockchain DAPP wallet emphasizes decentralization. It must run on the distributed network, and the application must be open-source. The data of DAPP application is encrypted and stored on the public blockchain, which can ensure that theThere are transactions that cannot be made public and encrypted.
Tokens are needed to encourage miners to verify and create blocks. Miners need POW work certificates in exchange for more tokens and rights. In short, token is an important driving force to maintain the development of a DAPP.
Although the development of blockchain DAPP wallet does not rely on any central server, it is inseparable from smart contract. Only by relying on the constraints of smart contract can blockchain DAPP be free from any centralized server or nodePoint to achieve autonomy.
The development of blockchain DAPP wallet can be freely packaged and produced by users, and its release will not be restricted by any organization. Everyone can publish their own DAPP on the blockchain without the help of relevant departments
to examine. DAPP data is encrypted and stored on the blockchain. The blockchain is responsible for the preservation and exchange of data, so that property rights transactions and sales can be carried out without intermediaries. At the same time, DAPP must ensure the participation of participants
Information is stored safely to protect personal digital assets and property rights from damage and disclosure.
