Know Your Language
Satoshi Nakamoto popularized blockchain programming in 2008. It is controlled through peer-to-peer networking as a widely used distributed ledger where nodes adhere to a set of rules. Blockchain has recently seen an increase in demand, and according to reports, its total contribution will soon approach $20 billion. Today we will understand the basic concepts of Blockchain by making these top 10 best blockchain projects for beginners.
One of the most well-known programming languages, Java, is also used to create famous blockchain programs, such as Ethereum, Hyperledger Fabric, IOTA, NEO, and others. Due to its relative shortcodes and more straightforward use, Python may be the ideal programming language to select for blockchain development. Python is open-source, so you can select from various resources and plug-ins. It is widely used in blockchain development, machine learning, and artificial intelligence and dynamically supports OOP.
Developers of blockchain programming recommend using C++ since it has a respectable amount of run-time polymorphism. The other possibilities include Ruby, Golang, and C#.
How To Choose The Best Project To Learn Faster
Blockchain is well-known for playing a crucial part in cryptocurrency systems like Bitcoin. It keeps a secure, decentralized log of cryptocurrency transactions. Blockchain can therefore eliminate the need for a third party and ensure the accuracy and security of data records. Immutability, supported by blockchain, makes it hard to alter or change previously recorded data. As a result, the blockchain prevents data manipulation on the network. Due to the decentralized nature of the blockchain, any network user can validate any data entered the blockchain. As a result, the public can have faith in the network. Blockchain technology is uncensored because it is not under the jurisdiction of a single entity. Therefore, a single authority, including governments, cannot stop the network.
One of the fundamental components of every bitcoin application is the ability to send and receive bitcoin. You can get an idea of the value of a bitcoin by safely sending and receiving it online. The peer-to-peer network is the setting for the Sybil assault. A hostile attacker desires this attack on the bitcoin network. A node in the network operates numerous identities simultaneously in this, undermining the reputation system’s authority. A database that is cooperatively shared, replicated, and synchronized by the participants in a decentralized network is known as a distributed ledger. Cryptography is used to store all the data precisely and securely on this ledger.
A web application communicates with a web server for its code and data, whereas a blockchain application communicates with a blockchain that contains both codes in the form of smart contracts and data in the blockchain itself. This is the key distinction between a web application and a blockchain application. Let’s now begin with some beginner-friendly blockchain project ideas. So let us, deep dive directly into and look at the top 10 best blockchain projects for beginners.
Top 10 Best Blockchain Projects For Beginners
1. Simple Storage
First, decide on the blockchain platform you want to use. Some popular options include Ethereum, Bitcoin, and Hyperledger Fabric. Next, choose a programming language that is supported by your chosen platform. For example, Ethereum supports Solidity, Bitcoin supports C++, and Hyperledger Fabric supports Go and JavaScript.
Write a smart contract that defines the rules for storing and retrieving data on the blockchain. You can use an integer variable in this contract if you can read it, update its value, and write to it. You can specify two functions, one to increase the defined variable’s value and the other to decrease it. As a result, it is now possible to create smart contracts that allow data modification rather than just read-only access. This contract will be deployed to the blockchain and will be executed whenever someone wants to store or retrieve data. Then Use an API or library for the chosen programming language to interact with the blockchain and execute the smart contract. Test your storage system to ensure that it is working as expected, and finally, deploy your storage system to the blockchain.
Additionally, once you understand how to alter the data in a smart contract, you may expand its usefulness by including new features and making it more useful.

2. Multi-Send
The concept is to create blockchain software to send ether to numerous Ethereum addresses. Like how you would use another user’s email address to send an email, you would use an Ethereum address to transmit ethers. Therefore, users could transmit ether to a list of Ethereum addresses using this application. When paying staff, this tool can be helpful. You must now create an Ethereum smart contract to build this project. To do this, you can utilize REMIX IDE. The Remix is a web-based IDE for creating solidity-based smart contracts. You only need to declare a function that will execute a straightforward for loop inside of and accept an array of addresses as input. You will be able to complete this project easily without a tutorial after completing the projects.
Key Concepts Covered:
- Blockchain Distributed Ledger
- Coinbase Transaction
- Blockchain Key Areas

3. Ether Wallet
Basically, a wallet that lets you use your ethers for purchases. You’ll build a smart contract for this project to accept ether from other addresses and send ether to other addresses. Although this type of smart contract is not practical, it is excellent for learning. Working on this ether wallet project will teach you how to work with or update ether in a smart contract. And it’s crucial to realize this because the strength of smart contracts depends on their capacity to move funds. You will also study access control.
Anyone might take your money if we allowed everyone to withdraw ethers. Therefore, a necessary statement will generally be needed to implement this access restriction. You will find it much easier to complete advanced projects once you have completed such simple projects. After completing this ether wallet project, you can attempt to construct a smart wallet.
Key Concepts Covered:
- Blockchain Distributed Ledger
- Coinbase Transaction

4. Polling System
A polling smart contract where people would have the option to construct new polls in this voting system and include various options in those polls. The alternatives above would each receive one user vote. Everyone will be able to cast a ballot within the voting time that you select. One of the options would be the winner after the voting session. Any issue may be the subject of these polls. Addresses will be a part of this smart contract, and you’ll learn more complex data structures like hashmap. It will be a little more interesting because you’ll also learn how to work with time in Solidity when creating voting period functionality. This project is a little challenging, but you may also include it in your portfolio.
Key Concepts Covered:
- Bitcoin Miners
- Blockchain Hash Functions
- Blockchain Block Hashing
5. Time lock Wallet
A time-lock smart contract is a wallet that locks your crypto assets for a predetermined period. That means that even if you wanted to, you wouldn’t be able to withdraw your cryptocurrency assets. Such wallets have a variety of applications. However, one of the most important uses of a locked wallet now is to stop you from selling your crypto assets when the market crashes. People frequently sell their cryptocurrencies after the market crashes out of fear of losing all their invested funds. But as we all know, holding onto cryptocurrency for a long time is necessary if we want to generate extremely big returns. Locking your cryptocurrency in a time-lock wallet is one way to accomplish this. This will prevent you from withdrawing it for a specific period.

6. To-do List App
Making a to-do list app driven by Ethereum smart contracts is the next project concept. You can get knowledge about the specifics of blockchain technology and blockchain applications in general by creating this application. We utilize a web browser and a web server to store all the code and data for our application in a straightforward to-do list online application. However, you need to use a different approach if you want to create a to-do list app for a blockchain. You must use a browser to access your to-do list and connect to the client-side application you will create rather than connecting directly to a server. This client-side application will really communicate directly with the blockchain rather than a web backend and a database.
The code for our to-do list app will be written in Ethereum smart contracts and stored on the blockchain. The blockchain itself will be used to store all of the to-do items. The smart contract will include every item on our to-do list and provide us the ability to add new items, designate items as complete, delete items, and more.
Key Concepts Covered:
- Bitcoin Miners
- Blockchain Hash Functions
- Blockchain Block Hashing
7. Voting System
Building a voting system is the third intermediate blockchain project concept. A great illustration of how blockchain technology and smart contracts may be utilized to improve system trust and transparency is voting. Voting can be done using this program at both the organizational and national levels. You must take certain precautions for your voting system to function when developing this project. Due to privacy concerns, you should first hide user information in your application. To accomplish this, you must employ an Ethereum address, which will serve as the users’ sole means of identification. Second, each voter should be limited to casting one vote, and then only when they are eligible to do so. Then, provided that all voting regulations are observed, it should be transparent. The votes must, after that, of course, be correctly recorded and tallied. There shouldn’t be any errors or room for fraud in the voting process. Solidity will be used throughout. Enjoy working on this project!

8. Savings and Lending Application
The following project concept is to create a lending and savings application. Decentralized finance, or DeFi, is currently quite popular. DeFi is essentially a method for transferring current financial solutions to the blockchain. People frequently engage in this behavior when lending and saving. People would be able to borrow money using this application on the blockchain. This basically allows them to lock up some assets, borrow other coins, and pay them back later, after a predetermined period. Trading cryptocurrencies is a distinct application for this kind of software. Traders can lock up certain cryptocurrency assets to borrow another type of asset, which they can then trade and profit from. Let’s now talk about the technology that would be required to construct this.
A large portion of these applications will use smart contracts. You must use the Solidity programming language to create smart contracts before deploying them on the blockchain. The business logic necessary to oversee the protocols for loans and savings will be contained in the smart contract. There will be opportunities in the future for many kinds of products like this because consumers are constantly looking for cheap rates. Just like there are several bitcoin exchanges, there can be many loan and savings platforms.
Key Concepts Covered:
- Blockchain Distributed Ledger
- Coinbase Transaction
- Blockchain Key Areas
- Blockchain Cryptocurrency
9. Decentralized Cryptocurrency Exchange
One of the concepts out of the top 10 best blockchain projects for beginners is a decentralized bitcoin exchange. This bitcoin exchange would not be live on a server because it is not a custodial exchange. It will enable you to possess and manage the cryptocurrency’s private keys. A decentralized cryptocurrency exchange would make it possible for most cryptocurrency users to trade their coins at some point in the future. Idex is one such instance of a program. You would need to develop some trading-related smart contracts to build this. Any Ethereum assets, including the Ethereum cryptocurrency itself and any Ethereum-based tokens, should be tradeable through your application. Once you have the necessary smart contracts in place, you will need a client-side interface so that users can interact with and use your application.
To create the interface, you can use any backend framework, such as React.js, Node.js, Angular, Django, etc. You’ll also need a library to turn your web application into a blockchain one. Web3.js is a library that transforms your web application into a blockchain website. You can communicate with smart contracts inside of a standard website using Web3.js.
Key Concepts Covered:
- Bitcoin Miners
- Blockchain Hash Functions
- Blockchain Block Hashing
- Blockchain Distributed Ledger
- Coinbase Transaction
- Blockchain Key Areas

10. Blockchain Wallet
Blockchain Wallet is the first cutting-edge blockchain project concept. Many people use cryptocurrencies, and they all need a way to manage their money. They will be able to store these monies and move them to many other wallets thanks to blockchain wallets. Trusted wallets, Coinbase wallets, and Argent wallets are a few instances of blockchain wallets. These wallets’ primary use is to store cryptocurrencies. However, some wallets also function as dapp browsers. In essence, they have a web browser integrated into them that enables the operation of blockchain-based applications. These wallets enable the user to sign transactions with their private key, which is a requirement for blockchain applications.
Now, how would you construct something similar? To create the native application, you can use Flutter or React Native. The blockchain must now be connected to this application. Web3.js would be useful for this. Web3.js is a library that, as was previously mentioned, transforms your web application into a blockchain website.
