How Blockchain May Help Future-Proof Your Software Development Career

blockchain software development

With the public meltdown in the cryptocurrency market in 2022 garnering so much attention, it might be easy to miss the opportunities being created by blockchain technologies in other areas. In fact, ​​experts expect that the global blockchain market will generate revenue of over $94.0 billion by the end of 2027. With that in mind, it’s easy to see why DevSkiller reports a 552% increase in interest in blockchain technologies and the developers needed to build blockchain-based solutions.

So, which industries and use cases can benefit most from blockchain technology? What new skills might you need? Which skills will be most useful?

In this blog, we’ll try to answer these questions and give you insights into how you might consider blockchain as a way to future-proof your software development career.

How are organizations leveraging blockchain?

Cryptocurrency may be the first thing you think of when you hear the word “blockchain,” but its capabilities extend far beyond that scope. In fact, companies across many industries are actively using blockchain to:

  • Increase transparency: Users in a blockchain system can easily see and monitor transactions, and this increases legitimacy and accountability. Examples include:
    • Ethereum—A community-run technology that powers the cryptocurrency ether (ETH) as well as thousands of decentralized applications.
    • OpenSea—One of the largest web3 marketplaces for NFTs and crypto collectibles. 
    • Rarible—An aggregated web3 NFT marketplace.
  • Ensure traceability: Users can see where products originate from and how they move through a supply chain. This is proving especially useful in tracing food products, organic products, and luxury goods. An example includes:
    • Luxochain—An authentication service for luxury goods, such as designer handbags, allowing buyers to validate that a seller actually owns the product, and whether that owner is the original owner
  • Validate transactions with smart contracts: Programs that automate the execution of an agreement, so that all participants have the ability to immediately validate the agreement’s outcome, without losing any time or requiring the involvement of an intermediary time loss. Smart contracts are especially useful in real estate, business transactions, and bank loans. Here’s one interesting example:
    • ChromaWay, in partnership with Swedish telecom giant Telia, is using blockchain to digitize contracts for property mortgages.
  • Enhance event ticketing and attendance: Blockchain can help users avoid misplaced tickets, replace damaged tickets, and prevent quick response (QR) code forgery. These solutions can also offer ticket holders exclusive benefits at the event or even become event memorabilia and valuable collectibles after the event. Solutions based on this proof of attendance protocol (POAP) are gaining traction with large enterprises such as Pepsi:
    • At the Strength of a Woman Summit hosted by Mary J. Blige and Pepsi, attendees were offered a selection of four commemorative POAPs featuring artwork from Shaylin Wallace, Rachel Winter, Amber Vittoria, and Varvara Alay. POAPs were displayed live at the event, and attendees could prove physical attendance in the form of digital tokens, while also collecting awesome art. 
  • Increase community participation with membership passes: With blockchain, brands are discovering new ways to connect to their communities. NFT-based membership passes can offer loyal consumers exclusive rewards that can increase in value over time. NFT projects from Bored Ape Yacht Club’s parent company Yuga Labs are well-known examples, but even global brands are exploring innovative ways to leverage this capability:
    • Time, a major global media company is developing a Web3 community to “bring together artists, collectors, and fans in a collaborative manner with the goal of building utility and community value over the long term.” 
  • Connecting digital and physical worlds through phygital goods and experiences: Phygital (a compound word composed of “physical” and “digital”) pairs in-real-life (IRL) experiences or physical goods like toys, jewelry, art, and clothing with NFTs, offering brands new ways to engage with consumers. For example:
    • The Whiskey Barrel Scotch Club is an NFT brand that authenticates individual bottles of Scotch whiskey on the Solana blockchain. While users assemble their own custom digital collection of Scotch, the company ships the physical bottle that corresponds to each NFT to the physical address provided.
  • Creating and selling NFTs using generative AI: The use of generative AI tools such as DALL-E 2 and ChatGPT has soared in the last year. Bringing generative AI into NFT creation is opening up new opportunities, and ultimately, many NFTs may be created almost entirely by Al. Here’s one interesting example:
    • Alethea AI and Polygon launched the AI Collectibles campaign, which allows anyone to use Althea’s CharacterGPT, a generative AI system, to rapidly create, train characters, and then trade characters as NFTs on the Polygon blockchain. 

What programming languages should you learn for blockchain?

There are many options when it comes to choosing a programming language for blockchain development. Your choice should balance what you enjoy doing and the industry or project you would like to work on. For example, if your product is regulated by an entity or must meet certain regulatory requirements, then you should explore using a private blockchain option such as R3’s Corda. If your solution interacts with smart contracts on the Ethereum ecosystem, then you will likely want to use Solidity and JavaScript

Here’s a quick overview of the major blockchain programming language options and where they are most commonly used.

Blockchain language Common uses
C++ A little-known fact in the blockchain world is that Bitcoin is written in C++.  It’s also used in Ripple, Bitcoin Cash, Litecoin, Stellar, and Monero. Its speed and efficiency make this highly versatile language an excellent choice for blockchain and other web3 projects.
Golang (Go Programming language) Originally designed at Google in 2007, Golang is an open-source programming language focused on simplicity, reliability, and efficiency.

Examples of blockchain projects written in Golang include Hyperledger Fabric and Go-Ethereum.

JavaScript and web3.js or ethereum.js Web3.js and ethers.js are open-source JavaScript libraries used to connect a web application to the Ethereum blockchain ecosystem. Examples of how JavaScript can be used in blockchain solutions include:
  • Hyperledger Fabric SDK for node.js is a widely used framework in the IT industry and corporations. It provides a simple API to submit transactions to a ledger or query the contents of a ledger with minimal code.
  • With Thirdweb, you can easily build web3 apps, smart contracts, and developer tools for Ethereum, Polygon, Solana, and more. 
  • Lisk SDK, written in JavaScript, lets you build applications on top of the Lisk blockchain. 
  • NEAR lets developers write smart contracts right in JavaScript.
Python With its simple syntax, Python has become one of the most popular blockchain programming languages. Developers use Python to write smart contracts for Hyperledger Fabric as well as for Neo.
R3 Corda R3 Corda uses Kotlin and Java, and it is mainly used to build distributed ledger applications for the financial industry. As an open permissioned blockchain, Corda shares data only with the parties involved in the transaction.
Rust A general-purpose blockchain programming language that was first developed in 2006 by former Mozilla developer, Graydon Hoare. 

Developers widely consider Rust for building immutable, innovative, and secure blockchain solutions. It is ideal for projects such as Solana, Polkadot, Hyperledger Sawtooth (for financial institutions), and the privacy coins Zcash (for anonymous transactions). 

Rust is also used to build smart contracts on blockchains like NEAR.

Solidity Built specifically for creating smart contracts on Ethereum, one of the most popular decentralized software platforms powered by blockchain technology. It is widely known for ether (ETH), its native cryptocurrency.

When it comes to blockchain, the key is staying curious

It’s exciting to learn about all the unique and innovative ways blockchain is being applied in the world today. By expanding our knowledge and building new skills, we can make sure that we’re part of this rapidly growing area of software development. I hope this post will inspire you to continue learning and helping others who may need your encouragement and insights. As Charles Darwin wrote:
