Creating Klaytn Blockchain Applications - Theory and Practice

Hello everyone!! It's been a while. I'm Son Se-jong, a blockchain instructor. It's been 4 years since NFT, so I've created a new course. I've worked at 6 North American blockchain startups and recently, I've created a course based on the knowledge I've gained from a blockchain game startup. GameFi will be a really important trend going forward. DeFi, NFT, and then web3 games 🎮.

Those who are interested in games and blockchain will be able to learn really enjoyably. We will use Next.js, Node.js, and Solidity, a smart contract, along with full-stack Next.js and Node.js. We will use the Phaser3 game engine to add a blockchain layer to the Snowman game and create a web3 game. We will learn about the popular Polygon blockchain, Alchemy, and Moralis. I think this is the only web3 game course in Korea.

I hope you'll hear more detailed explanations in the lecture , and by the way, there's a 20% discount for 5 days. See you in the lecture! Adios!!

hello everyone!

I'm thinking of creating another course after a long time to provide you with more up-to-date information.

I'm thinking of creating an advanced course on dApp development using Polygon Matic Layer 2.

Concepts to utilize :

- Hard hat testing & deployment
- Meta Transaction
- EIP-712 (signature)
- Byconomy
- Chainlink
- Onchain Monkey
- Polygon Bridge
- Transac

The above concepts are not limited to NFTs, but can also be applied to DeFi or other dApp development.

If you are interested in taking a paid course, please leave a comment.

We will create a new space once the target number of participants is reached, approximately 50 minutes :)

Hello Clayton students.

Three things for those who like Clayton and are taking classes at Clayton Course

I am contacting you to make an announcement.

1. Ground X, Jeju Creative Economy Innovation Center, and Jeju Blockchain Hackathon Collaboration

The Blockchain Hackathon is back again this year. This year, we are collaborating with the Jeju Creative Economy Innovation Center and Klaytn.

We are holding the Jeju Blockchain Hackathon based on this. This year, we are holding a special event for 3 nights and 4 days, including accommodation.

They said they will support us. (Of course, the airfare and accommodation are free!) The reason why one day was added compared to last year is

There weren't many opportunities for blockchain developers to network with each other, but the day before the hackathon,

They say they are even holding a networking event. Developer network, blockchain development, and even fun.

The hackathon you can take part in will be held in Jeju Island from November 7th to 10th. If you are interested in the hackathon,

Please spread the word to those who have it.

[Jeju Blockchain Hackathon Schedule]

Schedule: Thursday, November 7 - Sunday, November 10

*Pre-Orientation: October 18th

Location: W360, Jeju-si, Jeju-do (Old Meteorological Administration)

Application link: www.jjbw.io

Benefits: Free Jeju airfare/accommodation

2. Introducing the Klaytn Developers Facebook Group

For those interested in blockchain services through Klaytn, Facebook on Klaytn

We run a developer group. If you join Klaytn Developers on Facebook, you can

You can directly ask questions and receive answers during development.

Don't forget to join Klaytn Developers Facebook.

Address: https://www.facebook.com/groups/klaytndevelopers/

3. Introduction to the lecture on creating Klaytn Klaytn blockchain applications

As you know, I am going to teach you how to create a Klaytn blockchain application using ERC-721.

It has been done. Since it is compatible with Ethereum, you can also do ERC-721 on Klaytn.

There is. Through this lecture, you will create an application using ERC-721.

Address: https://bit.ly/2nMS4rs

I ask for your continued interest in Clayton, and I hope you will study Clayton through my lectures.

Contribute to the ecosystem too.

thank you

hello everyone!

Did you take the basic course well? :)

Kakao's Klaytn mainnet was launched at the end of last month.

Accordingly, many platforms and games based on Clayton will be gradually released.

Blockchain applications are becoming increasingly important and becoming a reality.

So ;) Among the most important concepts in blockchain applications, tokens (ERC20/ERC721)

First, we plan to produce a paid intermediate course based on Klaytn using ERC721 (IPFS, tx fee payment, etc.)

Since this may be a difficult concept to understand, I will explain it easily by creating a BApp myself.

If you are interested in taking the course, please leave a comment.

We will create a new one once the target number of people is reached :)

Take the Kakao Blockchain Project - Klaytn lecture
If you leave a review, you will be entered into a drawing
We're giving away AirPods and a super cute, high-quality genuine Kakao doll.

The method is simple.

1) Take a free lecture.
2) Write a course review.

> Limited to those who have written a course review by June 3rd.
