Vaccine traceability system based on blockchain smart contract

introduction

The system is based on Ethereum's Solidity for smart contract development and is deployed on the local machine through hardhat. Unit tests are written through Mocha and Chai, and a React-based front-end interface is provided to interact with users.

Introduction to blockchain

It is not difficult to see that blockchain technology has had a huge impact on the existing economy and society. In the future, more and more mature applications will appear. At the same time, the development of blockchain technology will also have a huge impact on human Internet activities.

According to the weak centralization characteristics of the blockchain system, the future blockchain system architecture will be to build a multi-centralized system. As blockchain applications continue to expand, blockchain technology will be applied to more industries in the future. In addition, blockchain technology has the characteristics of storing data and contracts through chains, which can only be read and written, but cannot be tampered with. This also brings unlimited possibilities to the socialization of smart contracts.

In general, there is still a very broad space for the development of blockchain technology in the future, and blockchain technology will also be developed in more and more fields.
