We asked blockchain engineers about things they don't know about the "on-site" things, such as "annual income," "work environment," and "BC development costs."

Although the word "blockchain" has already been used in many places, many people say that the actual situation is still unclear.

Therefore, we asked an engineer who is actually involved in blockchain development to tell us what blockchain development is like.

In this article, I would like to ask about the work of a blockchain engineer and shed some light on “blockchain,” which is often difficult to understand.

What do blockchain engineers develop?

What does a blockchain engineer do?

Mr. A: My job is to implement and develop blockchain-related applications and the blockchain itself.

What is the difference between the two?

Mr. B: To begin with, blockchain is not a system that can do anything by itself.

For example, a blank Excel sheet with nothing written on it is not useful to people. By entering some data into Excel, sorting it, and calculating it, you can finally help people.

Mr. A: Blockchain is essentially a database for storing and exchanging data, so if it just sits there blank, it has no value to general users.

Using that infrastructure, you will need an application to exchange crypto assets and issue and sell NFTs.

In this analogy, Excel is the blockchain, and the data entered there and the calculation processing are the blockchain applications.

Are there more engineers who develop blockchain itself or engineers who develop applications?

Mr. B: In my position as a blockchain engineer, I think that what I develop most of the time is overwhelmingly the latter, and both myself and Mr. A do, applications.

Mr. A: This is because there are already many blockchain infrastructures in existence. If we are to create a new blockchain, there is a big issue of how to disseminate that chain.

It is not very realistic to develop a new blockchain and overtake the many well-known chains that already exist. Therefore, many engineers are creating applications that run on blockchains that are already in operation.

The most famous one is Ethereum, so most blockchain engineers develop applications that run on Ethereum. Of course, there are some people who are developing Ethereum itself, but they are a small percentage of the total.

Mr. B: There are many other blockchains, but Ethereum currently holds the majority of the market share, so I think there are probably the most engineers developing applications related to Ethereum.

Moreover, there are many blockchains other than Ethereum that are influenced by Ethereum. From an engineer's perspective, if you can develop an Ethereum application, you can often use those skills when developing other blockchain applications.

Mr. A: However, not all applications are visible to general users. We also develop applications for blockchain-related companies such as exchanges to use in their business operations.

What kind of applications do blockchain engineers develop?

Mr. A: Even though we are blockchain engineers, the work we are responsible for varies widely and varies from person to person, so it is difficult to generalize, but things like wallets, blockchain games, systems for DeFi, etc. are things that are difficult for users to see. Blockchain engineers also create systems for managing exchange funds.

The question is, ``What do programmers create? 'It's like hearing '. There are programmers who create business systems for companies, and there are programmers who create servers for smartphone applications.

Anyway, think of a blockchain engineer as someone who is creating some kind of blockchain-related application. It really depends on each person what exactly they are making.
