Top 15 Blockchain Projects Ideas

A lot of people believe that Blockchain is just limited to cryptocurrency like Bitcoin but the world of blockchain is much more expansive than the latter. Blockchain can be described as a distributed and immutable ledger that is totally transparent. Let's go over each complicated term individually. It's distributed, meaning that every user within the network will own their own version that is part of the Blockchain. It's immutable which means the information in blocks cannot be altered. A ledger is similar to an notebook that keeps notes of transactions. Blockchain is an distributed method that ensures that all transactions and data is secured. Blockchain is an extremely efficient technology, which is the reason why today every business is looking to incorporate blockchain technology into their operations, and that is why they are searching for blockchain developers.

Blockchain is an entirely new concept and the best way to learn about it is to do some hands-on activities rather than studying documentation or taking online classes. In this article we'll look at the top 15 blockchain-related projects concepts that you can use to demonstrate your expertise as blockchain developers. If you're just trying to learn about blockchain development, these projects can aid you in establishing your understanding. If you're a person looking to become a blockchain engineer professionally, this is a project you could use as a portfolio to display your skills and knowledge. For each idea we will go over the basic concept the necessary knowledge required to build the project a success, the features should you include as well as the process of building it, the types of technology and tools you'll need to construct it, the programming language you'll have to master and some real-world examples you can get on for inspiration. So, let's move on and dive into the list of blockchain-related projects to consider. We'll also give you the source code URL as well as some tutorials to allow you to begin developing your dream project today.

Blockchain Project Ideas

All blockchain-based applications consist of two major parts - Smart Contract and Interface(front-end). There is no doubt that the front-end, also known as User Interface is crucial. Because it allows users to interact with your app, but in the case of blockchain applications , the aspect you must concentrate about is your Smart contract. Smart contracts are the software which contain an application's business-related logic app and operate on a blockchain. They are developed with Solidity, which is the Solidity programming language. In order to master blockchain development, you need to master the solidity programming language. Once you've learned Solidity language, you will need to understand how a blockchain app functions and how it's distinct from other web-based app. The main distinction between a standard internet application and Blockchain application is that a normal web application communicates with the web server for its data and code, whereas blockchain applications talk to an blockchain that has codes in the form of smart contracts, as well as the information in the actual blockchain. So, let's start by introducing blockchain idea for novices.

The Best Blockchain Projects for beginners

Here are five blockchain-related projects for beginner, as well as some tutorial sources and links. Keep in mind that these projects are not intended for your portfolio. They are intended for education purposes only.

1. Hello, World!

Essential Information: None

Idee: The very first concept you could use is to print the string "Hello the world!". This will be an extremely easy smart contract that can return the string "Hello the world!". While it may seem like a simple concept however, if you're an absolute beginner, it will show you many things. It will help you understand the basics of a Blockchain project. It will show you how to design an a solidity file, the way to create contracts as well as how to declare functions and many other basic aspects.

Source Code: Hello World

2. Simple Storage

Requires Information: None

Concept: The next project idea you could implement is a basic smart storage contract. For this type of contract you could use an integer variable to ensure that you are capable of reading this variable as well as modify the value. There are two functions you can define, one to increase an amount of value for the variable declared, and another for decreasing the value. Now you are able to create smart contracts that aren't just read-only, but actually alter the information. When you are able to alter the data within the smart contract, you can enhance its functionality by adding additional functions and making it more efficient.

3. Multi-Send

Requires Know-how: Solidity, Ethereum

Concept: The next idea is to create a blockchain-based application that allows the sending of Ethers to multiple Ethereum addresses. Similar to sending emails, you utilize an email address from another user, when sending Ethereum, you utilize an ethereum account. With this application, users can send ethers to a set of Ethereum addresses. This application could be helpful in sending employees salary. To build this application, you will need to create an Ethereum smart contract. You can use REMIX IDE to do so. Remix, an online tool for developers that allows creating smart contracts with the Solidity Language. It is all you need to do is define a function that can use the array of addresses as an argument. Inside this function, you will need to create a simple loop. After completing the previous projects, you'll be able to accomplish this task easily without any help.

4. Ether Wallet

Requires knowledge: Solidity, Ethereum

Concept: Coming to the fourth project concept the Ether Wallet. It is essentially a wallet that lets you use your ethers to spend. This project will build an intelligent contract that is capable of receiving the ethers of other addresses and transfer them to other addresses. Smart contracts such as these aren't particularly useful, however they're excellent to study. This project on ether wallet will help you learn how to modify or modify ether within the form of a smart contract. This is an extremely important aspect to be aware of since the strength of smart contracts is the ability they have to move money. Also, you'll learn how to control access. If we let everyone take ethers out, anyone is able to steal your cash. You'll require a declaration to perform the access controls. After completing these basic projects, you'll be able to complete advanced projects with more ease. It is also possible to make an Smart wallet after completing this ether wallet design.

5. Polling System

Essential knowledge: Solidity, Ethereum

Concept: The next project idea is to create a smart polling contract. The system for polling users could create a new poll and within that poll, they will be able to provide several options. The voters would cast their votes for one of those options. You'll establish a period for voting and everyone will be able to vote. After the period of voting one of the options will be the winner. These polls could be connected to any subject. If you implement this smart contract , you'll have to handle addresses. You'll also learn more sophisticated data structures such as hashmap. Additionally, you'll learn how to handle time in solidity when implementing voting period functions which will be more exciting. This is a somewhat challenging project, and you could highlight this project on your portfolio too.

Intermediate Blockchain Projects

Now, let's look at some ideas for intermediate blockchain projects which you could include in your portfolio or resume.

1. Time lock Time lock

The initial idea for a project within this category is a the Time Lock Smart Contract. A smart contract with a time lock is a kind of wallet that will keep your crypto assets secure for a set period of time. This means that you will not be able to cash out your crypto assets even if you wish to take them out. You can use these wallets to serve a variety of purposes. One of the most important features of the lock wallets is to stop the sale of your crypto assets during the market crash. In times of market turmoil, many typically sell their cryptos due to the fear of losing their entire saved money. However, we are all aware that if we are looking to earn a significant profits in crypto, we must be able to keep it for a lengthy duration. One option is to put your cryptocurrency in an account with a time lock. By doing this you'll be unable to withdraw your crypto for a specific period of time.

2. To-do List App

The next concept for the project is to develop a to-do list application powered by Ethereum smart contracts. Through this app you can understand how blockchain works and how blockchain-related applications function generally. In a straightforward to-do-list web application, we employ an internet browser and web servers to store all the data and code in our program. However, to build a complete to-do list app on blockchain, you have to create a different. instead of directly connecting to the server you will need to access your to-do list using your browser. Then, you're connecting to the client-side software you create. The client-side app isn't going to communicate with an online backend or a database, but instead connect directly to the blockchain. On the blockchain, we'll have our code that is written in smart contracts based on Ethereum which will comprise all essential business logic that will be used in our app for a to-do list. The items on our list will be stored on the blockchain. This smart contract is going to include all tasks on our list of tasks and will permit us to add additional tasks, mark completed and delete tasks, among other things.

3. Voting System

The 3rd intermediate blockchain idea for a project is to create Voting systems. Voting is an excellent illustration of how blockchain and smart contracts can be utilized to increase confidence and transparency to the system. This app can be beneficial in conducting elections on an organizational scale and also on a national scale. While developing this application, you should be aware of a few things to ensure that your system of voting function properly. First, the information of users must be kept out of your application to avoid privacy concerns. To do this, you'll need to make use of an ethereum account which is the sole identification for users. In addition, each person is allowed to cast only one vote and only if they are eligible. Additionally, it should be clear with a guarantee that the rules of voting are adhered to. In addition, it is essential for all votes correctly registered and counted. There must not occur any error or fraud possibility in the system of voting. This will all be conducted with a solid foundation. Enjoy this project!

4. Savers Application as well as Lending Application

The next idea for a project is to create an application for savings and lending. Decentralized finance, also known as DeFi is the hottest current trend. DeFi is essentially a method to take existing financial services and then transferring them to blockchain. Saving and lending is one segment that is being used frequently. With this app, individuals could get loans through blockchains. This means that they could secure certain assets as well as borrow other cryptocurrency and pay them back after a set period of time. Another use-case for this type of app is the trading of cryptocurrency. The traders can secure certain crypto assets to take an alternative type of asset, trade it for an income. Let's consider the kind of technology be required to create this. Smart contracts will form the main component of these applications. You will need to write smart contracts using the solidity programming language and then put them into the blockchain. The smart contract should contain all the necessary business logic to manage the lending and saving protocols. In the near future there will be opportunities for different types of such products, since just as there are many cryptocurrency exchanges, there will be multiple savings and lending platforms as people are always searching for affordable rates.

5. Decentralized Cryptocurrency Exchange

The last idea for a blockchain-based initiative in middle-of-the road category would be a decentralized crypto exchange. This is an exchange that is not custodial, which means it isn't on a server. This will let you manage and own those private keys for your currency. There are many cryptocurrency users on the market and they all wish to exchange their crypto at some point and an exchange that is decentralized will allow them to do this. One example of such an app could be Idex . What is the best way to create this cryptocurrency exchange that is decentralized? In order to build this it is necessary to design smart contracts to manage the trading. The application must be capable of trading all types of ethereum assets, the cryptocurrency, and all tokens based on ethereum. After you have your Smart Contracts in place for this, you will require an interface for clients to allow users to use your application and utilize it. To build the interface you could use any backend framework such as React.js, Node.js, Angular, Django, etc. In order to transform your web-based application to a blockchain-based application you'll need an appropriate library. A library that transforms your website into a blockchain website , and this is the place where web3.js are. Web3.js lets you connect to smart contracts within the normal web page.

1. Blockchain Wallet

Blockchain Wallet

The most advanced blockchain project idea is Blockchain Wallet. There are a lot of cryptocurrency users and they are looking for a way to control their money. Blockchain wallets enable them to store the funds and transfer them to other wallets too. Examples of blockchain wallets are trust accounts, Coinbase wallet, and Argent wallet. The principal use for these wallets is holding cryptocurrency. However, some wallets function as dapp browsers , too. In essence, they come with built-in web browsers that allows you to use applications that are based on blockchain. Blockchain-based applications require a method to verify transactions using the private key of the user and that's what the wallets can accomplish. What is the best way to build something similar to this?. You can make use of React Native or Flutter to develop the native app. You must now connect the program to the blockchain. For it, web3.js would be helpful. As mentioned earlier, Web3.js is a library which transforms your web site into a blockchain-based website.

2. Digital Asset Marketplace (DAM)

The next concept for project is a Digital Asset Marketplace. Many people own digital objects of collectibility (digital asset) and require an area to purchase as well as sell their items. Digital asset marketplaces , or DAM offer a complete platform for their customers. DAM are a reliable intermediary between investors and issuers who invest in the digital currency. They provide a variety of services and tools to facilitate transactions between different users. To develop this type of application , you will require some smart contracts for Ethereum developed in the solidity programming language. You will need an online application as well as the web3.js library to convert the web application into a blockchain-related website.

3. Peer To Peer Carpooling

The next concept for project is a peer-to-peer carpooling app. The majority of carpooling services are controlled by one company. It is possible to create an intelligent contract that will connect the driver and rider directly, without the involvement from any third party such as Uber and Ola. Companies such as Uber and Ola are the sole owners of all the information of drivers and of their customers, which could cause privacy issues. If ride-sharing and car rental are transferred to blockchain, we could create a more secure and efficient carpooling system.

4. Skill Verification System

The next concept for the project is to develop a system to verify skills. Social media platforms let users make claims about themselves that is assumed to be the truth, even though they aren't. The system for assessing skills would verify skills in a straightforward and impartial manner, including a decentralized consensus. The skills of the participants are judged in anonymity by random other users. They will verify and confirm the claim, and be rewarded for their effort. For example, if a person knows everything about react.js They would make an claim and include evidence like their Github repos, then other members of the same domain would confirm the claim. Based on the consensus of the group, the claim can be either 'endorsed', or 'flagged'. You could build this application by using Ethereum smart contracts.

5. Systems for Fake Product Identification

The latest and most advanced blockchain idea is to create a fake product identification system. As we know, all brands have a counterfeit copy of it available. Every brand is a fake producers that offer the exact same product at less expensive costs, without compromising the quality. Even experts from the original manufacturer might not be able to identify fake items from their actual items. What happens if we utilize blockchain technology to recognize genuine products and attach the QR code during the manufacturing. This QR code for the item is linked to the Blockchain. It is possible to store the information about the product as well as the generated QR codes for that product in blocks in the database. Users will now be capable of scanning the QR code on their smartphones , and it will be able to tell them if the item is genuine or not. The scanner will then compare the QR code with entry from Blockchain database. Blockchain database. If the code is found to match the database entries, it will send an alert to the buyer that the product is authentic and if not, an indication that the item is not authentic. This is a fascinating and beneficial idea for a project, and if you are able to implement this , then you can be sure that major brands will be waiting to be knocking at your door!
