What Is Blockchain Programming?
First, let’s talk about blockchains.
A blockchain is a decentralized database or ledger managed by computers in peer-to-peer networks.
It stores data in blocks that are then linked to other blocks to create a data chain.
A blockchain’s DECENTRALIZED nature guarantees a tamper-proof way to store digital transactions.
Before a blockchain network is released, certain features and protocols that form its architecture should be written in code.
Blockchain programming uses languages such as C++ and Java for writing smart contracts or decentralized apps (DAPPs).
Popular Blockchain Programming Platforms
Hyperledger and Ethereum allow for building DAPPs that run on blockchain technology.
With the former, it offers tools that support the development of distributed ledgers through an easy-to-use application programming interface (API).
Ethereum is an open-source blockchain platform that supports smart contract development.
Smart contracts are built using the Ethereum programming language, Solidity, which runs on the Ethereum Virtual Machine (EVM).
What Skills Do I Need to Learn Blockchain Programming?
There are several skills that every blockchain developer should have.
Companies may have varying demands on the level of expertise and experience. Regardless, here are the ESSENTIAL skills for a successful blockchain programmer.
Programming is crucial in learning blockchain development. It encompasses a broad category of skills, including coding and web development.
Web developers should have a working understanding of coding in different languages for web and blockchain development.
Coding skills are necessary to properly manage and secure data, keep up with network demands and maintain seamless transactions.
Strong knowledge of an object-oriented programming language is essential to work with the most common programming languages for blockchain.
2: Blockchain Architecture
As an aspiring developer, understanding how the blockchain world operates is a MUST.
There are several key concepts that developers should be familiar with, such as:
- Hash functions
- Smart contracts
- Distributed ledgers
Whether you’re designing blockchain as a core developer or building blockchain apps as a software developer, knowing blockchain architecture is only the beginning.
On top of that, acquaint yourself with the different types of blockchain architecture. Different types of architecture have different strengths and weaknesses.
Depending on what you’ll be doing, understanding these types is essential for blockchain developers to maximize their coding skills.
Blockchain is gaining notoriety as one of the new paths to STRONGER SECURITY, offering superior resistance against cyber criminals.
With its layered digital cryptography and decentralized nature, blockchain relies on digital security to protect data and prevent manipulation or hacking.
A developer needs to know the best practices to reduce risks against attacks.
In particular, learning how blockchain’s Distributed Ledger Technology (DLT) works is valuable to understand how to maintain a chain’s security.
As cyber-attacks gradually evolve, so should blockchain developers.
Similarly to cybersecurity, cryptography guarantees security protection against unauthorized access in a blockchain network.
You’ll be working with several cryptography concepts, such as:
- Hash functions
- Symmetric and asymmetric keys
- Digital signatures
These concepts form the foundation of the blockchain. They ensure that each block is SECURELY connected to other blocks on the blockchain.
5: Data Structures
Blockchain developers work with different data structures to apply them in the blockchain network.
Each block is a data structure that clusters transactions in a public ledger. It can refer to a single block or as many as an entire blockchain.
These structures serve as the framework of all blockchain networks.
It’s a gateway to learning more about complex skills such as data storage, data defense, and distribution.
6: Smart Contracts
Smart contracts are self-executing contracts that enable two network parties to exchange data without needing a third-party intermediary.
All blockchain solutions and interactions use smart contracts.
Since most blockchain activity involves transactions, smart contracts are INTEGRAL for transparency and network fluidity.
If you’re interested in blockchain programming, learning about smart contracts is necessary to understand how they apply to various networks.
Factors to Consider When Choosing the Best Blockchain Programming Languages
Below are the necessary factors to consider when choosing the ideal blockchain coding language for your needs:
The programming language you pick should align with your plans in blockchain development.
Although there are many languages, they have different tools suitable for different purposes.
Find the best ecosystem for your project to discover the programming language that best fits your plans.
Choose what you want to provide to your users, your potential partners and where you want to see your project.
2: Personal Skills
If you’re already skilled in a language, say Java, you can be sure of its reliability and the tools it offers.
But perhaps you’re new to programming. The other languages that are easy to use, like Swift and Kotlin, are accessible even to budding developers.
Choose the programming language you’re familiar with to ensure the best results.
Of course, the performance of the programming language is also an important aspect to look into.
Check the runtime efficiency of different languages to determine if they can run your tasks more productively with fewer crashes and errors.
Using a high-performing programming language with optimized code will save you time and effort in the development process in the long run.
The innovation of blockchain is its security system. Therefore, using a language designed with security will make it more resistant to attacks.
Programming languages like Java and C++ have safety features such as data hiding and secure interfaces to reduce threats.
If you eventually decide to add more team members to your project, a language that is easy to scale will make onboarding more manageable.
Choose a language with simple syntax and a concise codebase for easier readability for new developers.
