A blockchain serves as an electronic database for storing data in digital form. Currently, most blockchain projects are monetary, but their usage in KYC systems, hospitals, vote chains, etc., is gaining momentum.
Blockchain is a decentralized system that encrypts all transactions and data. As we all know, blockchain is a highly powerful technology, which is why every company is actively attempting to integrate blockchain technology into their operations.
Blockchain is a new concept, and the best way to learn it is through hands-on experience rather than reading posts or watching online lectures. In this article, we will go through the top blockchain project ideas that you can use to demonstrate your expertise as a Blockchain Developer. If you’re just getting started with blockchain programming, these blockchain projects will help you consolidate your knowledge. And if you’re looking to make a career as a Blockchain Developer, you can include these projects in your portfolio to demonstrate your expertise and creative skills.
So, let’s get started with the list of blockchain project ideas.
This is one of the simplest blockchain projects for beginners. The idea is to print the string “Hello, People!” This will be a basic smart contract that returns the string “Hello, People!” Although it appears to be a basic concept, there is a lot you can learn. This project will teach you the fundamentals of a blockchain project. It will show you how to set out a solidity file, how to define contracts, how to define a function and other fundamentals.
A basic storage smart contract is the next project concept you can execute. In this contract, you can use a float variable and ensure that you can read and alter its value. You can declare two functions: one for increasing and one for decreasing the total value of the defined variable. So you can now create smart contracts that are just not read-only but allow you to edit the data. And, if you understand how to edit the data in a smart contract, you can expand its usefulness by introducing more functions to it and creating it more useful.
The following concept is to create a blockchain application capable of sending ethers to various Ethereum addresses. Just like you would use another user’s email address to send an email, you would use an Ethereum address to transmit ethers. Users would be able to give others to a database of Ethereum addresses using this application. This tool is beneficial when it comes to transferring wages to employees. To complete this project, you must first create an Ethereum smart contract. You can achieve this with REMIX IDE. The remix is an online IDE for creating smart contracts in Solidity. You only need to create a function that takes an array of addresses as an input and runs a loop within it.
The fourth project concept is Ether Wallet. A wallet where you can spend your ethers. In this project, you will build a smart contract that can accept ethers from other addresses and send ethers to other addresses. Smart contracts like these aren’t that helpful, but they’re excellent for learning. This project will show you how to modify or update ether in a smart contract. This is vital to comprehend since the efficacy of smart contracts is derived from their ability to move money. Access control will also be covered. If we allow a user to withdraw ethers, the user can take your money. To provide this access restriction, you’ll need to employ a needed statement. After working on such simple projects, you will be able to do more complex blockchain projects with more ease.
Here we have some intermediate blockchain technology project ideas that you can add to your portfolio.
A time lock Smart Contract is one of the best blockchain projects for students in this category. A time lock smart contract is a wallet that keeps your virtual currency locked for a predetermined period. This implies that even if you want to, you won’t be able to withdraw your virtual currencies. We may utilize such wallets for a variety of purposes. However, one of the most important applications of this time lock wallet is to prohibit you from selling your virtual currencies during a market downturn. People prefer to trade their crypto when the market drops because they are concerned about losing all of their funds invested. But we all know that to make a significant profit in cryptocurrency, we must be able to retain it for a long period. One method is to keep your virtual currency in a time-lock wallet. You won’t be able to redeem it for a specific period in this way.
A decentralized cryptocurrency exchange is a next suggestion for a blockchain-based business in the intermediate category. This is a non-custodial cryptocurrency exchange, which implies it will not be available on a server. It will allow you to possess and manage your cryptocurrency’s private keys. Some cryptocurrency users want to swap their assets at some point, which a decentralized cryptocurrency exchange would enable them to accomplish.
To build this, you would need to design some smart contracts to handle the trade. Your software should be able to exchange any sort of Ethereum resource, including the Ethereum cryptocurrency and any Ethereum-based tokens. Once you have the smart contracts in place, you will need some kind of client machine so that users can integrate with and utilize your application. You can create the interface with any backend framework, such as Node.js, React.js, Angular, or Django. You will need a library to transform your web application into a blockchain application. Web3.js is a library that converts your web application into a blockchain website. Web3.js allows you to communicate with smart contracts from within a website.
The third idea for an intermediate blockchain technology project is to create a voting mechanism. Voting is an excellent illustration of how blockchain and smart contracts can be utilized to improve system trust and transparency. This program is used to perform voting both at the organizational and national levels. You must ensure certain things while developing this project for your voting system to function properly. Due to privacy concerns, user information should be obscured in your program. To do this, you must employ an Ethereum address which will serve as the users’ exclusive identity. Second, each person should only be allowed to vote once and only when they are eligible.
Following that, it should be clear under the condition that all voting rules be observed. Then, of course, the votes must be precisely registered and tabulated. The voting mechanism should be free of errors and the risk of fraud. All of this will be accomplished through the use of solidity.
The following project concept is to create a savings and lending application. decentralized finance, also known as DeFi, is now popular. DeFi is a method of transferring current financial services on the blockchain. Saving and lending are two aspects where individuals do this often. People would be able to get loans on blockchains using this application. That is, they lock up some valuables and lend other coins, then repay them after a certain period of time. Cryptocurrency trading is a separate use case for this type of application. Dealers can lock up certain cryptocurrency property to borrow another type of asset, then exchange it and profit.
Let us understand what type of technologies you would need to build this. The majority of such apps will be based on smart contracts. Smart contracts must be written in the Solidity programming language and then deployed in the blockchain. All the core functionality for managing the saving and lending procedures will be embedded in the smart contract. There will be potential for numerous innovations like this in the future because just as there are multiple bitcoin exchanges, there can be multiple loans and investment platforms as individuals are always seeking at fair costs.
Let’s discuss some advanced blockchain projects.
If you are looking for blockchain projects for final-year students, Blockchain Wallet is a comprehensive blockchain project concept you can build to showcase your learning. There are a lot of bitcoin users out there that wish to handle their assets. Blockchain wallets will enable them to save their funds and move them to other wallets. Coinbase wallets, Trusted wallets and Argent wallets are some instances of blockchain wallets. The primary use of such wallets is to store cryptocurrency. However, some wallets also function as dapp browsers. They basically have a built-in web browser that allows you to run blockchain-based applications. Blockchain applications require a method to authenticate deals using the user’s private key, which these wallets provide. The native application can be built with React Native. You must link this application to the blockchain. You can use Web3.js in this case. Web3.js is a library that converts your web application into a blockchain website.
The following project concept is Digital Asset Marketplace. Many individuals own digital assets and they require a marketplace to acquire and sell them. DAMs, or digital asset marketplaces, offer their consumers a full framework. DAM acts as a trustworthy mediator between digital asset issuers and investors. They provide a range of tools and services to make transactions between users easier. This type of application would necessitate the use of Ethereum smart contracts built in the solidity programming language. You need a web application and the web3.js framework to convert this into a blockchain website.
The following is the best blockchain project concept that aims to create a skill verification system. People create any claim about themselves on social media sites, and it is often considered true even if it is not. This skill validation system would validate skills objectively, utilising decentralized consensus. Random people would anonymously assess skill specimens. They would be rewarded for their efforts after verifying and validating the claim. For example, if someone claims to be an expert in react.js and attaches proof such as their Github repositories, other members from the same industry will check it. The assertion is either ‘approved’ or ‘flagged’ based on the consensus.
A fake merchandize identification system is the next sophisticated blockchain project proposal. As we all know, every brand nowadays has a knockoff out there. Every well-known brand has imposters that sell the same thing at a lower price while sacrificing quality. Even the original company’s specialists may be unable to discern between fake and genuine items. What if we used blockchain technology to recognise genuine commodities and apply a QR code to them as they were being manufactured? The product’s QR code will be connected to a Blockchain. We can keep the product specifications and generated QR codes in the database as blocks. People will be able to scan the QR code with their cellphones, which would notify them if the products or services are genuine or not. The scanned QR code will be compared to records in the Blockchain database. If the code matches, the buyer will be notified that the goods are genuine; otherwise, the buyer will be notified that the product is counterfeit. This is a highly fascinating and beneficial project concept, and if you effectively do the blockchain implementation, big brands will surely come your way.
Blockchain is a new technology. As the software sectors are hunting for competent blockchain engineers, working on blockchain projects will undoubtedly offer you an advantage over other candidates. In their projects, the majority of students create standard web apps or mobile applications. However, block chain implementation entails going a step further. You will create a web or mobile application and then convert it into a blockchain application. Thus, working on upcoming crypto projects and including blockchain projects in your CV indicates that you are also skilled in web development or mobile development. Moreover, there is a lot of space for creativity in the blockchain sector. There are so many unexplored opportunities in this area that you should explore.
In this article, we have discussed some of the best blockchain project ideas that you can make and include in your portfolio to help you stand out from the crowd. We’ve glimpsed how Ethereum smart contracts and an interface are used to build any blockchain application. We also underlined the significance of the Web3.js library in the development of any blockchain application.
