The Essential Skills Required to become a Blockchain Developer

The term Cryptocurrency is near impossible to ignore ever since the very first cryptocurrency Bitcoin took the world by storm. Well actually the very first cryptocurrency was called E-Cash and was created in 1983 way before the term ‘cryptocurrency’ was coined.  Despite the fact that blockchain is widely connected with cryptocurrencies, it is now increasingly being used across other domains. The growing popularity of blockchain has given rise to blockchain development which is providing countless opportunities across the globe for both existing software developers wishing to transition over to this lucrative sector and those who are keen on learning blockchain development either by themselves or via one of the many courses available. 


Blockchain developer is one of the most sought after blockchain jobs and the demand is only going to increase dramatically over the coming years. Currently demand outstrips supply and there are very few experienced blockchain developers out there given how young this sector is. Interested?  Well you should be; this is one promising career for those who have the technical chops.

So what are the key skills one needs to become a blockchain developer?

Blockchain Architecture


As a blockchain developer you must have thorough understanding of the blockchain, how it operates and of course its architecture. Topics like cryptographic hash functions, consensus and distributed ledger tech and so on, require hands-on experience. In fact there are plenty of blockchain jobs posted for blockchain architects. If this areas excites you than consider this as a specialty and take your new career in this directions. We promise you won’t go hungry.

The blockchain architecture is typically divided into three kinds namely:

1. Public blockchain architecture

The likes of the Bitcoin, Ethereum etc fall into this as the public/anyone can access the data if they want

2. Private blockchain architecture

As name suggest access to the blockchain is restricted to a group or organization and one would need a invitation to gain access.

3. Consortium blockchain architecture

A blockchain controlled by a group of organizations that agree on who can access and how it is regulated.

Blockchain Architect: a great career in itself

The blockchain architect technically sits on top of that of blockchain developer and are usually in charge of leading the projects and outlining overall roadmaps. It is a career that goes beyond coding, requiring knowledge of business and and also the ability to communicate effectively with people both on the development team and even clients hence ideal for those who enjoy a little social interaction.

Smart Contracts


It is important to understand smart contracts and their relevance to business now they are becoming increasingly and widely adopted. Almost every blockchain solution wants to use them. It is advised to learn languages such as chaincode, solidity and viper.  

Data Structures


Data structures are ultimately what build the blockchain as every block is essentially a type of data structure and developers will be using them extensively as they build out networks. A thorough knowledge of data structures is imperative. Take a look at https://academy.horizen.io/technology/advanced/blockchain-as-a-data-structure/

Web Development


Blockchain developers typically invest a big chunk of their time on developing web apps. This is very important as many companies work with blockchain developers to develop better Dapps so that people with limited to no knowledge of blockchain could use them with ease. Having a solid understanding of web design and web development best practices is going to be very important for any blockchain developer since many blockchain jobs require this knowledge.   

Cryptography

This is essential for a developer to grasp given that any blockchain transactions of a cryptocurrencies takes place through encryption and decryption of public and private keys.  The crypto wallet proves your ownership by storing your private keys allowing you to receive, send and spend your cryptocurrencies. 

Key Languages you must know

Becoming a competent blockchain developer isn’t something you can just learn overnight. We can see there are many areas to cover and a number of programming languages contribute to the blockchain developers toolbox. Here are the main ones you need to focus on:

C++  Used to create Bitcoins core and generally a very useful language when performing various blockchain tasks 

Python Should need no introduction given how powerful, popular and useful this language is with anything relating to data. It is a super versatile language and used for both back and front end development.


Java  Although it has been around for a long time is is a very useful language and relatively easy to learn. To understand how it and python are used in blockchain check out this course by the blockchain council https://www.blockchain-council.org/blockchain/java-or-python-which-suits-blockchain-better/

Is Blockchain Development Right for You?

If you are already a software developer there are few reason why you wouldn’t want to get on board and start contributing to this exciting sector. If however you are starting from scratch it might be advisable to check out some free courses first and see how you get on with the material.

It is worth remembering that just because there is a shortage of blockchain developers does not necessarily mean it is easy to find a job if you are just starting out. There are might be plenty of blockchain jobs for developers yet often employers are seeking developers with at least a couple years of experience or can prove they have the skills to do the work. That said the future is extremely bright for anyone training for any of the skills above and there will always be work on the specific areas mentioned. Perseverance is key and keep an eye on any internships/entry level roles.
