Becoming a Blockchain developer in Korea is a sure-fire way to make money in Korea. The Korean government has stated time and time again their desire to research Blockchain technologies. Add this to the fact that there are Blockchain projects that spring up every single week in Korea. Investors in Korea are still looking to find the next big Blockchain project. Therefore there is a high demand for Blockchain developers in Korea. It is estimated that you can easily earn up to at least $80,000 dollars a year to start. Many will think that becoming a Blockchain developer is impossible without any programming experience. This is actually not true. I will give you some resources to help you become a Blockchain developer in Korea.

Why become a Blockchain Developer in Korea?

It is one of the highest-paying fields in tech right now in Korea. Blockchain Developers and Cloud Engineers are in high demand. However, Blockchain developers in Korea make more than AI programmers, big data analysts, and software developers. As I mentioned above, you can get a starting salary of $80,000 dollars a year as a Blockchain developer in Korea. This is still below the US average which is double that. Just having a year of experience in Blockchain development can get you into the six figures.

So what is the catch? The major catch is that you will need to know at least some level of Korean. Most job postings in Korea are written in Korean and headhunters in Korea focus on developers that can communicate in Korean. If you are interested in working in Korea you probably know some level of Korean. For those that do not, I would recommend spending a year to get your TOPIK level to at least level 3.

Tips on Becoming a Blockchain Developer in Korea

Blockchain Developer in KoreaWork for a Korean Blockchain Company or Startup

Your first goal should be to work for a Blockchain company in Korea. NOT to start your own Blockchain startup in Korea. This is key as starting a business of your own in Korea requires so many additional responsibilities which we will not cover in this article. Working for a Blockchain company in Korea will be easy because of the number of companies looking into Blockchain technologies. The moment you publish your Korean resume on any job-finding platform in Korea, you will be swarmed with job offers.

Remember to have your resume translated into Korean. Most job postings will be in Korean or it will state that you will need to be business fluent in Korean. However, because the demand of Blockchain developers in Korea is so high, many who don’t speak Korean can still get the job. However, when applying make sure your resume is in Korean to get you to the next phase.

Work on Blockchain Applications and not Protocols

You want to be a Blockchain developer that works on applications that are built on top of existing Blockchain technology. For example, if you compare this to the web, you don’t want to build web-browsers like Chrome, but rather websites. So the question is, what has the highest demand in South Korea? Cryptocurrency exchanges and Blockchain apps for gaming are both great avenues to take in South Korea. Furthermore, many fintech companies and gaming companies in Korea are aggressively looking to incorporating Blockchain into their current business.

Become a Blockchain Developer for Ethereum

If you want to be a Blockchain developer in high demand, I would suggest you go with Ethereum which allows you to run small programs called smart contracts. Knowing smart contracts, in general, is critical for Blockchain developers. Most Blockchain projects in Korea end up choosing Ethereum because it is much more flexible than other Blockchains. EOS is a close second but Ethereum developers are much bigger than EOS. Therefore there is much more help out there and Ethereum has a greater chance of surviving in the long run.

Study up on Dapps that have had success (Cryptokitties)

Don’t spend too much time here but it is important to see some of the successful Dapps built on Ethereum. Ethereum has over 2,500 applications Dapps, so only pick the top ones which you can find on DappRadar or a Dapp list website on Google.

Another road you can take is to look into Klaytn. Klaytn is a global public Blockchain platform developed by Ground X, the Blockchain subsidiary of Kakao. Take a look at some of the top Klaytn Blockchain apps to get inspired.

Focus on Gaming Dapps or Decentralized Exchanges

Blockchain Developers in KoreaNow narrow your niche down to either gaming or decentralized exchanges (DEX). There are many Korean gaming companies looking into Blockchain games for 2020 and beyond. Same with cryptocurrency exchanges in Korea. Due to many Korean cryptocurrency exchanges getting hacked, at some point, they will need to look into becoming a decentralized exchange. Being the first fully decentralized cryptocurrency exchange in Korea will have huge potential for not only getting funding but acquiring users.

Go to Udemy and Learn these 5 Development Tools

Udemy is probably the best place to learn how to become a Blockchain developer. There are other platforms out there but I found Udemy to be the best. There are reviews by other members and you can learn at your own pace. The key tools & libraries to learn are

  • Web3
  • Remix
  • Solc
  • Ganache
  • Truffle

Spend a few hours each to get a better understanding of each development tool or library. I would suggest giving yourself a month during this process. Knowing these development tools and libraries inside out will put you well ahead of other candidates in Korea.

Learn Smart Contracts

Being able to do smart contracts is the main part of being a Blockchain developer for Ethereum. Solidity is used for writing smart contracts. It is very similar to Javascript but you will have to type each variable yourself which is why it will take longer. Many Blockchain companies in Korea just need a Blockchain developer for smart contracts. This one skill alone can get you a job as soon as possible.

Build a Dapp

During your interview with a Korean Blockchain company, you will need to show that you can build a Dapp. This is why it is important to build a Dapp before you apply for any job. This could cost you some money but it will be worth it in the end. You will need a website, Metamask, and smart contracts. There are communities out there you can go to for help. Most Blockchain developers don’t even have a Dapp to show during their job interviews. If you have a Dapp, it is almost certain you will get a job in Korea.

Focus on Ethereum 2.0!

Ethereum 2.0Ethereum 2.0 opens up a world of new possibilities. Dapps are going to get really fast, highly scalable (100,000 transactions per second), and will be able to compete in the open market. Ethereum 2.0 is an upgrade to Ethereum and is sometimes called Eth2 or Serenity.

The major change some from moving to a proof of stake consensus mechanism (previously was proof of work) where there are validators instead of minors. The validator’s role is to propose new blocks, provide computing power, storage, and bandwidth to validate transactions. The validators are then given periodic payouts in the form of ETH. Moreover, proof of stake is a more energy-efficient mechanism compared to proof of work since it uses less computing power to secure a blockchain.

Another change comes in what is known as Sharding. Sharding is the process of splitting one blockchain into multiple blockchains known as shards. Every validator will maintain information related only to their shard which is shuffled regularly to avoid any form of manipulation.

Ethereum is the largest general-purpose Blockchain in today’s market. Currently, there are over 1,500 Ethereum projects that are being built. The upgrade to Ethereum 2.0 will take place in three phases (0,1, and 2). Phase 0 was launched back in December of 2020 with the implementation of the Beacon Chain. Phase 1 will happen in 2021 with 64 shards expected to launch. Finally, Phase 2 will happen in 2022 where the shards will become fully functional and compatible with smart contracts. Therefore, by end of 2022, Ethereum 2.0 will garner more and more interest from investors and startups which is why it is important to learn it now.
