The Vital Guide to Blockchain Interviewing

“What the internet did for communications, blockchain will do for trusted transactions.” - GinniRometty, CEO of IBM

The recent explosion of cryptocurrencies such as Bitcoin has helped shine a light on a powerful new technology, known as blockchain, it is set to revolutionize the world we live in.

Blockchain is a system of records, comprised ofdata blocks. These blocks represent a continuously growing list that acts as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way." - Harvard Business Review.

Most blockchains are managed by a decentralized network of peers and are secured using cryptography. Each new block links to a previous one to create a complete digital ledger that can be traced back all the way to the very first block ever written. This digital ledger contains a timestamp and other transaction data. Once created, this data cannot be altered without permission of more than 50% of the network, something that, in effect, makes blockchain databases immutable.

Why blockchain has the power to change the world

“When we have smart contracts on the blockchain, it can result in Decentralized Autonomous Organizations, or organizations without management or employees, run completely by code”. - Mark Van Rijmenam (Founder of Dataflow).

Or to put it another way…

“Instead of putting the driver out of a job, blockchain puts Uber out of a job and lets the taxi driver work with the customer taxi directly.” – VitalikButerin

Blockchain technology has already started a powerful new revolution. Forget about Bitcoin, the enormous potential of blockchain technology is only just starting to be implemented. Currently, top blockchain developers are racing to come up with exciting new ways to put this technology at the very heart of the global economy. Such is the potential of blockchain that some of the biggest companies in the world are currently investing heavily in the technology. The race to findblockchain developers is on.

Probably the most famous single blockchain project being developed at the current time is the Ethereum network. The Ethereum Project has set about using this new technology to underwrite digital contracts that can be used by separate parties via a peer to peer network. The potential use of these contracts is almost limitless.

Individuals and companies could use these blockchain contracts for everything from labor exchange to storing registries of debts or property transactions. Some of the many potential uses of blockchain technology include an electricity distribution network that allows home users to sell excess electricity they generate, a housing property ledger that helps speed up the process of selling a home, preventing money laundering, and even helping to improve food safety.

The potential size of the future blockchain industry is estimated to be in the tens of billions of dollars. It is therefore unsurprising that there is a gold rush going on right now as companies seek to exploit and develop this new technology in order to gain a slice of this lucrative pie.

But how can companies hire blockchain developers and be sure they get the best ones when they are in such demand? Well, the good news is that here at DevTeamSpace, we have already amassed a wealth of experience creating blockchain software, and right here in the USA too.

To ensure that you get the best possible product, you will need to make sure that you hire the top blockchain programmers out there. This is often something which is easier said than done, especially for inexperienced startup project managers who don’t have a strong background in software engineering.

The good news is that we have developed an extensive network of blockchain developers for hire who have already been through the process countless times and so understand the process back to front.

So to help your company find a top blockchain specialist or blockchain developer team, we have put together DevTeamSpace’s ‘Vital Guide to Blockchain Interviewing’.

Blockchain developers for hire: How a good interview can help you find the best one

Finding an expert blockchain developer is never an easy task. During an interview, most specialists will promise the world and to guarantee to meet all your expectations. Sadly, in reality, things often turn out quite differently.

Poor quality code that leads to bugs and poor performance, missed deadlines, and a whole host of other development issues are just some of the nightmare scenarios that many project managers end up having to face on account of poor software developers.

Making sure that you really are hiring the best blockchain developer can be easy when you know how. The key is to make sure that you ask the all the right questions during the interview so that you can really be sure you separate the best from the rest.

What if I have no experience or background knowledge in interviewing blockchain developers?

No matter whether you are looking to hire developers for ICO or find Solidity developers for hire, a good interview technique can help plug the gaps in your knowledge and help you find just the person you are looking for.

Our guide will furnish you with all the questions that you will need to find that perfect programmer. Even if you are experienced in interviewing blockchain developers, it is certainly worth reading this guide to see if there are any helpful tips or questions that could help you in the future.

What Makes A Good Blockchain Developer?

This is the million dollar question, as they say. Since blockchain is still in its infancy, most project managers naturally assume that it requires special software engineers who have a unique set of skill sets and previous experience.

The reality is that though blockchain development does require specific understanding and knowledge of the technology, a great deal of the traits that make a good app or web developer, also make a good blockchain developer.

However, you will need to make sure all your developers have a good understanding of blockchain technology and in whatever blockchain network you plan to use. With Ethereum, for example, they should know how to code in Solidity, understand how its smart contracts function, and know the rules of the Ethereum Virtual Machine or EVM.
