Blockchain technology has been around for a while now. Thanks for stopping by. Here we’re doing our bit to rescue you out of your contraption and make you understand the meaning of Blockchain. Then we’ll sum up by listing a few blockchain programming languages useful for creating blockchain applications. So, let’s begin!
What is a Blockchain?
A Blockchain is a distributed digital ledger that holds a continuously-growing list of data blocks in an ordered sequence. Every sequence of blocks contains a batch of transactions, that is secure from tampering, revision, or replication (e.g. as used for financial transactions in cryptocurrencies like bitcoin). These blocks are connected with each other via cryptography. It is a network of nodes that runs over a public network. Every record on Blockchain is timestamped and is controlled by a large network. Although every transaction is publically viewable, it is safe from tampering by any unauthorized individual.
How Does Blockchain Work?
- Developers define models with blocks and transactions
- They use a Transaction Pool to store raw transactions
- They use a hash algorithm to create immutability
- They create a block mining unit to mine blocks periodically.
- Blockchain Developers use embedio to view the blockchain in a web browser.
What To Do If You’re Not Already Engaged in Blockchain?
- As you learn about Blockchain and dig deeper into DeFi’s and NFTs, create a wallet on Metamask. Also create other wallets like Celo, Algorand, terra to see how their onboarding experience differs.
- Buy some cryptocurrencies (Cryptos). Funding wallets via wires is not feasible, therefore, use in-built services that let you buy crypto using your credit card.
- Make some transactions on Metakaskm such as transferring between the wallets. Metamask supports both ethereum and other less expensive Blockchains.
- Create an Opensea account and buy an NFT. try creating an account on NBA Top Shot.
- Open a Uniswap account.
What Is The Advice For Beginner Blockchain Investors?
Create a wallet for experimentation and keep very little value in it. All transactions are public and traceable. So create a learner account and remember that everything you do is public.

What Are The Best Blockchain Programming Languages?
To understand this, let’s first decipher the frontend and backend operations in Blockchain. A frontend is a webpage that you see in a mobile app or a website. Another part is the smart contract (a small program inside the blockchain).
In some cases, you not only have a front-end, a smart contract but also a backend and you decentralize that. In such cases, you may use blockchain programming languages like Node.js, and Python.
1. Node.js:
Best Node.js Blockchain libraries in 2023 are (1) mixin-node-sdk, (2) oci-blockchain, (3) ethairballoons, (4) Web3.js, (4) Ipfs-core, (5) Bitcoinjs-lib, (6) Coingecko-api, (7) Ethers.js, (8) Truffle, (9) CCXT. Node.js runs Javascript code outside of the browser. With many libraries in the forefront, Node.js estimates the properties of the block, installs dependencies, creates the blocks, and creates the blockchain.
2. Solidity:
Blockchain programming languages cater specifically to these two spots. The first programming language suitable for creating smart contracts is ‘Solidity’. It has a syntax similar to JavaScript. But actually, it is quite different from JavaScript. The second is the front-end so we use HTML for the structure of the page, CSS for styling, and JavaScript for the dynamic nature of the page. Learn Solidity if you want to build apps on Ethereum Blockchain. It is an object-oriented programming language, statically typed for writing smart contracts on Ethereum and other Blockchain platforms.
3. Rust:
It is primarily used for Solana Blockchain. Rust is preferable for Blockchain App Development as it does not have any garbage collector, which makes it indeterministic incident proof, during the runtime.
4. JavaScript:
It will help you in building the front-end of these applications.
5. Python:
Why is python useful for core blockchain app development? Python is best for beginners with easy syntax, shortcodes, plug-ins, open-source, oops, machine learning, and artificial intelligence implementations. A list of 428 Python Packages for Blockchain can be found here. Also, Python offers a graphical user interface (GUI) such as PyQt5, Tk, etc. Python Blockchain App Example: Creating a Blockchain using Python will require mining new blocks, and displaying the whole blockchain to store the data in JSON format. It is easy to read and implement. Multiple blocks can be aligned in a sequence to form a chain.
We’re emphasizing the use of Python for Blockchain App Development here due to its certainty and surety to eradicate any errors in the mining process. The available data is stored in JSON format. Multiple blocks add up in sequence, every minute. The fingerprinting is done with hash tables, using hashing algorithms. After mining, the block is added to the chain. The validity of the chain is checked after mining several blocks at once, to prevent any tampering. The web app is then made by using Flask and is deployed locally or publically according to the user’s need.
6. Go:
Programming solid, old-fashioned, PHP applications with JS frontend is a thing of the past. Golang (Go) can be used to build Ethereum, Dero, Hyperledger Fabric, and GoChain types of Blockchains. Setting up a Golang project on your local machine without any prior GoLang experience is easy. Golang makes it easier to generate and distribute the first blockchain tokens. A CLI-controlled database can easily be done in Go. It secures the database using a secure cryptographic hash function.
7. Java:
Implementing a simple Blockchain in Java starts with block mining, adding a block into Blockchain, calculating the hash, verifying the blockchain, verifying every transaction, applying alternate consensus protocol, mining the reward, checking the node types, securing the communication with cryptography and public key infrastructure. Java is the oldest and most popular Blockchain programming language to develop Blockchains on Ethereum, IOTA, NEM, Hyperledger Fabric, and NEO.
8. C++:
C++ is the successor of Java and C programming languages, which work on core object-oriented programming principles. The most popular blockchains developed in C++ are Bitcoin, Ripple, Litecoin, Monero, EOS, Stellar, and QTUM. It features runtime polymorphism, multi-threading, and function overloading. It is popularly used for Blockchain programming like Stellar, Bitcoin, Ripple, etc.
9. C#:
Every blockchain is written using a specific programming language. Like ethereum is written in Solidity, similarly, popular blockchains built on C# are Stratis, NEO, and IOTA.
10. Ruby:
Ruby blockchain programming language uses third-party APIs and plugins to allow multi-paradigm to create applications across platforms.
Popular Tools for Blockchain Programming
These are mandatory skills needed to become a blockchain developer:
- Remix IDE – Open-Source tool to write smart contracts
- Truffle Suite (with Truffle, Ganache, and Drizzle) – to get started with distributed apps
- Ethlint/Solium – To check security issues in smart contracts
Parity – It provides a fast and secure way to interact within a blockchain
