đĄThe Tech Behind Blockchain
If you want to become a developer it is important to understand the tech that makes blockchain and how everything comes together.
First things first, what really is blockchain?
Well, blockchain is a decentralized ledger that pushes transactions on a public or private network.
It also allows for secure, transparent, and efficient transactions without the need for intermediaries.
Immutability is at the core of blockchain which means that once a block is added to the chain, it cannot be altered or deleted.
That means each transaction on the chain can actually push a certain amount of data which stays there forever in the exact state that it was pushed on to the chain.
This helps to keep things transparent and relatively tamper proof as compared to the traditional centralized data storage systems or ledgers.
This makes it a secure and tamper-proof way to store and transmit data. The transactions on a blockchain are verified by a network of nodes that reach consensus on the state of the network.
Blockchains themselves can actually be public or private in nature.
Bitcoin is a public blockchain that anyone can see, interact with & transact on.
Ethereum blockchain is another hugely popular public blockchain network that also allows people to build and publish dapps (decentralized apps) on top of it.
Private blockchains however, are restricted to a very specific group of users and are usually deployed by companies for internal purposes, such as supply chain management or identity verification.
Some companies that employ a private blockchain are Walmart, IBM, JP Morgan etc.
These are the underlying key concepts that make blockchain possible, and they are crucial for a blockchain engineer to design and develop secure blockchain applications.
For an aspiring blockchain developer it is also important to have knowledge about cryptography, data structures, and distributed systems.
đKey Trends in Blockchain Development
Blockchain is huge and within the industry there are certain buckets that drive things forward in their own way and with their own way of doing things.
Letâs quickly see what different trends have developed a strong foothold in the industry.
This would also allow you to understand what you resonate with the most within blockchain and where youâd like to take your developer career.
Developing in DeFi
First up, there's Decentralized Finance, or DeFi.
DeFi became a hot topic over the past few years and continues to be so. DeFi applications are decentralized financial systems that don't require intermediaries like banks.
Some examples of DeFi applications include decentralized exchanges, lending platforms, and insurance platforms.
Building something great in DeFi is not that easy and is a huge responsibility from a security perspective since peopleâs money is involved.
This means as a dev you will need to be on top of your game at all times and also be well versed with security and audit practices first hand.
This is also the reason why experience in DeFi is seen as a great plus for blockchain devs, particularly for those pursuing a career as a web 3.0 developer.
NFT Development
Another bucket to keep an eye on is Non-Fungible Tokens, or NFTs.
These are digital assets that are stored on a blockchain, and are used for things like art, collectibles, gaming, contracts etc.
NFTs are relatively new and gaming is emerging as a big use case. Tech such as smart NFTs that integrate with data oracles to pull on and off chain data to change form within the virtual ecosystem is really interesting and has a huge real world use case potential in the future.
As a blockchain developer, it's important to understand how NFTs work and how complex systems could potentially include NFTs as a value add rather than just a vanity metric.
Enterprise Blockchain Systems
As the advantages of blockchain become clear to people, huge businesses are choosing to integrate blockchain into their existing business processes.
Some great examples include supply chain management systems, identity verification systems, and payment systems.
If you have experience in developing enterprise blockchain solutions, you could be in a great position to capitalize on this trend.
In fact people who understand blockchain development are also a great asset from a consulting standpoint for a lot of huge companies across the world.
Interoperability Between Blockchains
As more and more blockchains are created there is an ever increasing demand for systems that can allow all these chains to communicate with one another in an efficient and secure manner.
It's definitely worth your time to keep an eye on the interoperability scene in the industry.
Once again even with this sector you will need to specially pay attention to security and data transfer systems if you want to create things that are robust.
đWhat Are The Challenges and Opportunities in Blockchain Development?
A big challenge that people in the crypto world face is how fast the industry moves. And the fact that crypto runs on a 24 hour cycle, it can become difficult to stay on top of whatever is happening around the world.
Since blockchain itself is not fully mature there is lots of research being published, inventions being pushed out and SOPs being modified. This makes it even more challenging to navigate.
A lot of projects do face regulatory uncertainty as well as the overall regulatory landscape itself isnât really clear yet in every country.
This sometimes can also make working in the industry a bit less predictable on top of the existing price volatility making it a tad bit more volatile than many people have the appetite for.
Despite these challenges, the crypto industry provides amazing opportunities for innovation and a large impact.
Developers are technically on the forefront of possibly revolutionizing many industries such as finance, supply chain management, gaming, arts, data & many more.
Some people might think that the fast nature of the industry means a lower job security but we believe it couldnât be further from the truth.
The industry is rapidly evolving with more and more opportunities cropping up every single day and demand for highly skilled developers increasing along with it. Consider learning web3 to meet this demand.
So there will always be a healthy demand for people who can do great work and because the people here love decentralization they are more open towards people having a healthy work life balance, getting paid more, and remote work!
Developers who keep improving their skill stack and make themselves adaptable can position themselves for success and shape the future of this amazing industry.
â¨ď¸What Are Some Essential Skills for Blockchain Developers?
Itâs important that we understand and build the skills required to become great blockchain devs. Youâll find a few key skills that we believe are necessary in order to become a professional at what you are going to do as a developer but as you can guess this is definitely not an exhaustive list.
Youâll find a few key skills that we believe are necessary in order to become great at what you are going to do as a blockchain developer but as you can guess this is definitely not an exhaustive list.
As time goes on and you get more hands-on experience as a web3 dev you will get to know what you donât know and you must then take time to learn those things to fill in the holes in your development skill set.
Alright then moving on!
Of course it goes without saying that programming skills are a must-have for blockchain developers, duh!
Solidity is the main programming language that most of the smart contract developers build with.
Solidity can be used in order to build on almost all the big blockchain ecosystems such as Ethereum, Polygon, Avalanche, Binance Smart Chain and many more!
We do recommend going through Javascript and basics of programming in general just in case you are totally new to development altogether.
Additionally you must make yourself familiar with data structures & algorithms, as well as object-oriented programming.
Cryptography is another component for blockchain, and you'll need a strong grasp of the fundamentals.
As a blockchain developer, you'll also need to understand how cryptography forms the base of blockchain.
So, this includes but is not limited to the knowledge of public key encryption, digital signatures, and hash functions.
For example, an understanding of how SHA 256 is used to get miners to mine Bitcoin blocks as well as Bitcoin wallet generation and transactions is going to be a must.
Youâll also need to understand peer-to-peer networks, consensus algorithms, and fault tolerance to create antifragile systems.
A senior software engineer who has worked on DAOs, NFT projects, who is also known as Naruto in the web3 world shared a valuable piece of advice for our readers:
Blockchain development is a very steep learning curve as compared to something like DSA or web2 in general. The web3 space is faster than most of the spaces/fields, so youâre in it for a sprint + marathon. Brace yourself. Code everyday, and join twitter to share your learnings. Commit meaningful codes everyday and share on twitter what you learnt.
Finally, soft skills like communication, teamwork, and adaptability are crucial to success as a dev in crypto.
Ideally we would also recommend learning the basics of social media as well as Crypto Twitter is a huge thing when it comes to interacting with others, building in public as well as building a strong network of people in the industry further helping you strengthen your career.
