New trends in front-end development: Web3, blockchain and virtual reality

Web3: the next generation of the Internet

Web3 represents the next generation of the Internet, which brings the development of the Internet to a new stage. Compared with traditional Web2, Web3 is more decentralized and gives users more control over their data. This trend brings some important changes for front-end developers.

Blockchain technology

Blockchain is one of the core technologies of Web3. It is a decentralized distributed ledger technology that ensures data transparency and security. In front-end development, blockchain can be used to create decentralized applications, meaning users have full control over their data. Developers can use blockchain technology to create digital identity verification, smart contracts, decentralized financial applications (DeFi) and other functions. Here is an example of a smart contract using the Ethereum blockchain:

pragma solidity ^0.8.0;

contract SimpleStorage {
   uint256 storedData;

   function set(uint256 x) public {
       storedData = x;

   function get() public view returns (uint256) {
       return storedData;

Decentralized Applications (DApps)

Front-end developers can use Web3 technology to build decentralized applications (DApps). DApps are applications built based on blockchain technology. They run on a decentralized network and do not rely on centralized servers. This provides users with greater data security and privacy.

// Use Web3.js to connect to the Ethereum network
const Web3 = require('web3');
const web3 = new Web3('');
