  • Web 3.0 is the next generation of the World Wide Web, where users are in control of their own data and identity.
  • Web 3.0 is built on decentralized technologies such as the blockchain, which allows for more secure and efficient transactions.
  • Ethereum is a decentralized platform that runs smart contracts: programs that automatically execute transactions when certain conditions are met.
  • EOS is a scalable blockchain platform that enables developers to build dApps with ease.
  • Hyperledger Fabric is a permissioned blockchain platform that offers high performance and flexibility for enterprises.

platforms such as Ethereum, EOS, and Hyperledger Fabric provide the infrastructure for decentralized applications (dApps). dApps can be used to build more efficient and profitable businesses by eliminating intermediaries, reducing costs, and increasing transparency by providing a tamper-proof record of transactions.

first step in building a dApp is to create a smart contract. Smart contracts are programs that automatically execute transactions when certain conditions are met. For example, a smart contract could be used to automatically send payments to suppliers when goods are delivered. This would reduce the need for manual invoicing and payment processing, which can be time-consuming and error-prone.

a smart contract is created, it can be deployed on a blockchain platform such as Ethereum, EOS, or Hyperledger Fabric. Deploying a smart contract on a blockchain platform makes it tamper-proof and immutable, meaning that it cannot be changed or deleted. This provides businesses with the assurance that their transactions will be executed as intended.

first step in creating a smart contract is to identify the business problem that you are trying to solve. For example, if you are a supplier, you may want to create a smart contract that automatically sends payments to your suppliers when goods are delivered. Once you have identified the business problem, you can then start coding the smart contract.

are many programming languages that can be used to code a smart contract, but the most popular ones are Solidity (for Ethereum), EOSIO Smart Contract Language (for EOS), and Go (for Hyperledger Fabric). Once your smart contract is coded, it can be deployed on a blockchain platform.

example Solidity smart contract can be built using the Remix IDE. The Remix IDE is a web-based IDE that allows you to write, compile, and deploy Solidity smart contracts. To use the Remix IDE, you first need to create a new file and give it a name. Then, you can start coding your smart contract in Solidity. Once your smart contract is complete, you can compile it using the Remix IDE. After your smart contract is compiled, you can then deploy it on Ethereum testnet using the Remix IDE.

This is an example Solidity Smart Contract.

The contract starts when a website goes up and ends when the site is not detectable for 5 days.
//SPDX-License-Identifier: GPL-3.0

pragma solidity ^0.8.7;

contract WebsiteMonitor {

    address owner;

    uint256 startDate;

    uint256 endDate;

    uint256 websiteStatus;

    constructor(address _owner, uint256 _startDate, uint256 _endDate) public {
        owner = _owner;
        startDate = _startDate;
        endDate = _endDate;
        websiteStatus = 1;

    modifier onlyOwner {
        require(msg.sender == owner);

    function updateWebsiteStatus(uint256 _websiteStatus) public onlyOwner {
        websiteStatus = _websiteStatus;

    function getWebsiteStatus() public view returns (uint256) {
        return websiteStatus;

    function getStartDate() public view returns (uint256) {
        return startDate;

    function getEndDate() public view returns (uint256) {
        return endDate;

    function isActive() public view returns (bool) {
        if (websiteStatus == 1 && block.timestamp >= startDate && block.timestamp <= endDate) {
            return true;
        } else {
            return false;


What is a smart contract?

A smart contract is a digital contract that can be used to create, store, and manage agreements between employers and employees.

What are the benefits of using a smart contract?

The contract can be used to track hours worked, compensation, and benefits, and can be used to automate payroll and invoicing.

Creating a smart contract

The first step to creating a smart contract for employment is to set up a new account with a digital wallet.

To do this, you'll need to create a new Ethereum account and deposit some Ether into it. You can do this through an online exchange such as Coinbase or Kraken.

Once you have an account set up, you'll need to choose a smart contract platform. There are many different platforms available, but we recommend using the Ethereum blockchain.

The next step is to create your smart contract. To do this, you'll need to write your contract code in Solidity, a programming language for smart contracts.

Once your contract is written, you'll need to compile it into bytecode, which can be deployed to the Ethereum blockchain.

You can do this using the online compiler at https://remix.ethereum.org/.

Once your contract is compiled, you'll need to deploy it to the Ethereum blockchain. This can be done using the online deployment tool at https://www.myetherwallet.com/.

Once your contract is deployed, you'll need to add employees and employers to the contract. This can be done by sending transactions to the contract address with the appropriate data.

When an employee or employer wants to view their data, they can do so by querying the blockchain using their public key.

To make sure that your data is secure, you can encrypt it using a tool like https://www.naclbox.com/.
