The Line ecosystem is expected to become a new engine for Web3 development

Introduction

Line, a popular messaging app in Asia, announced this year that it will merge its mainnet with the Korean public blockchain Klaytn. This strategic move indicates that Line will actively expand its footprint in the Web3 space. Looking back at the rise of the Telegram ecosystem, it successfully attracted a large number of Web3 projects and users through its strong user base and mini-program platform, becoming a bridge for the transition from Web2 to Web3. Now, Line also possesses similar development conditions and is expected to give rise to new Web3 phenomenon projects in the Asian market, injecting new vitality into this field.

The merger between Line and Klaytn will bring about technological innovation and changes in governance structures, issuing a new unified token and building an integrated network across Ethereum and Cosmos. This collaboration not only accelerates the development of Web3 technology but also signifies the deep cooperation among Asian tech giants in the blockchain field, bringing more innovation and opportunities to the entire industry. Therefore, Line has the potential to become a new engine driving the development of Web3, continuing the success story of the Telegram ecosystem.

TG Ecosystem Review

The rapid development of the TG ecosystem has not only attracted widespread attention in the Web3 field but also injected new vitality into the entire industry with its unique advantages and innovative models. Among them, the successful listing of multiple projects, especially those that have been listed on mainstream trading platforms and whose market values have rapidly risen, has not only validated the commercial potential of the TG ecosystem but also attracted a large number of new users into the Web3 world.

The reason why the TG ecosystem has achieved such remarkable results by mid-year is mainly due to its large user base and efficient communication mechanisms. Telegram itself, as a communications giant with 900 million users, has introduced mini-programs and bot development features, providing users with a brand new service experience. These mini-programs can not only completely replace most websites but also support seamless authorization and integrated payments. Through customized features such as automatic news delivery, information services, and popular mini-games, they have significantly enriched the ways users interact.

In addition, Telegram has developed the TON blockchain, which supports convenient blockchain transactions and further lowers the barrier for users to enter Web3. This "traffic + payment" model, similar to WeChat, has allowed Telegram to rapidly develop in the Web3 field and become a bridge connecting Web2 and Web3.

In this process, several projects within the TG ecosystem have stood out particularly. For example, some gaming projects have rapidly attracted a large number of users through simple operational methods and a viral mechanism, successfully guiding them to engage in on-chain interactions, thereby achieving the transition from Web2 users to Web3 users. These projects have not only succeeded within the TG ecosystem but have also seen their market value soar quickly after listing, demonstrating their strong market appeal and commercial value.

Some projects enhance players' understanding and recognition of virtual currencies through their unique game backgrounds and management elements. At the same time, by combining a task system with video-watching tasks, they effectively drive traffic to their own YouTube channels, further expanding the influence of the TG ecosystem.

The success of these projects not only brings a lot of fresh blood to the TG ecosystem but also provides new ideas and models for the development of the Web3 field. They prove that through gamification and socialization, it is possible to effectively attract and convert Web2 users, while also demonstrating the application potential of blockchain technology in non-financial fields such as gaming and social networking.

As the TG ecosystem continues to mature and improve, more application scenarios and business models will be explored and realized in the future. From the current development trend, the TG ecosystem will not only continue to delve into the gaming and social fields but may also further expand into multiple areas such as finance, education, and business, ultimately forming a diversified and open Web3 ecosystem. With the addition of more innovative projects and the participation of more users, the TG ecosystem is expected to become an important force in promoting the development of the Web3 industry.

Introduction to Line

Line is not only a popular messaging app in Asia, but it is also the most popular messaging application in Japan, with 95 million monthly active users as of 2024, covering over 68% of the total population of Japan. The main functions of this app are similar to WhatsApp, providing messaging and calling services, while it also has many other unique features, such as stickers. Popular anime, celebrities, and creators even sell their paid stickers within the app. Businesses can set up official accounts on Line, and some companies even sell their own stickers to support marketing campaigns.

Line also features a status update function, including an Instagram Stories-like feature and a seamless sharing button. In addition, the app has a cashless payment function called "Line Pay," allowing users to transfer money between each other and make payments in stores.

The number of monthly active users on Line has significantly increased from 58 million in 2015 to 95 million in 2024. Among active users, the proportion of male and female users reachable through advertising is 52.5% and 47.5%, respectively. The age distribution ranges from 8.3% for those aged 15 to 19 to 31.4% for those aged 50 and above, which is quite representative of the Japanese population.

In Japan, Line is not just a tool for young people. It is widely used by people of all ages and has become an important communication mechanism connecting friends, family, and colleagues.

A unique feature of Line is that over 3 million Line accounts in Japan are owned by companies. If you want to set up a business account on the app, you need to fill out a registration form and submit an application. Once approved, you can start using it. As the number of business accounts continues to grow in Japan, it provides an alternative to other marketing tools like email communication, offering many advantages to businesses. It is free to use, and companies can send sales coupons to customers through the app and even conduct surveys. Compared to email, it has a higher average open rate and click-through rate. This is why Line is used by businesses of all sizes.

In 2020, the Japanese Ministry of Health, Labour and Welfare (MHLW) reached an agreement with Line to conduct a nationwide survey on COVID-19. The MHLW's official account regularly sends health survey questionnaires to all Line users.

Today, Line has become one of the most useful brand tools in Japan. If you are considering creating your own official Line account while working with the Japanese market, this could be a good choice.

Current Status of Line Mini App

The Line mini app, as an innovative service on the Line platform, has become an important tool for digital transformation for businesses, especially popular in Japan and Taiwan. It allows businesses to directly publish web services on the Line platform, enabling users to enjoy a convenient service experience without the need to download additional applications. Thanks to Line's large user base, businesses can reach a huge potential customer group. Additionally, by integrating Line Pay, users can complete payments directly within the app, greatly enhancing the convenience of shopping.

With the impact of the COVID-19 pandemic, consumers are increasingly turning to planned purchases, which requires businesses to adapt to this change through digital means. The Line mini app has thus become a key tool for connecting online and offline (OMO), as it not only supports common functions such as online ordering, reservations, and queue management, but also helps businesses improve service visibility and user engagement. Although the development of the Line mini app has not yet been fully opened in Taiwan, certified partners can apply in advance, and once development is completed, it must pass Line's review before it can be released.

Currently, the Line mini app is widely used in industries such as catering, education, healthcare, beauty, and retail. It helps businesses stand out in a competitive market by providing a convenient user experience and strong backend support. With the continuous development of technology and further market opening, it is expected that the Line mini app will play a greater role in the future, especially in promoting the integration of online and offline.

In addition, as the market's acceptance of Line mini apps continues to increase, their numbers are growing rapidly. Some companies have launched no-code development platforms, further lowering the technical barriers, allowing more small and medium-sized enterprises to easily create and manage their own Line mini apps. It is expected that in the future, Line mini apps will play a greater role in e-commerce and online services, and may even drive Line to become a super app, providing users with comprehensive lifestyle services. This trend not only offers businesses a brand new customer touchpoint but also brings consumers a richer and more convenient service experience.

Introduction to the Korean Public Chain Klaytn

Klaytn is a blockchain platform launched by GroundX, a subsidiary of the South Korean internet giant Kakao, aimed at promoting the widespread adoption of blockchain technology through its high performance, scalability, and reliability. Klaytn uses a Proof of Stake (PoS) consensus mechanism, which not only speeds up transaction speed and confirmation times but also maintains the efficient operation of the system.

A key feature of Klaytn is that it integrates the advantages of both public and private blockchains, providing an environment that is both efficient and secure. This unique combination allows Klaytn to support a large number of transactions and users while maintaining low processing times and costs, which is crucial for commercial applications that require handling high-frequency, large-scale transactions.

Klaytn's native cryptocurrency is KLAY, which plays multiple roles within the system. As a payment method, KLAY is used in applications built on Klaytn, and it is also distributed as rewards to developers who contribute to the platform. Additionally, KLAY is a popular choice among cryptocurrency traders and investors who profit from market price fluctuations through trading.

An important milestone in the development of Klaytn was the merger with Finschia, which led to the birth of the new mainnet Kaia. Kaia combines the technological advantages of Klaytn and Finschia, aiming to create the largest Web3 ecosystem in Asia. The native token of the new mainnet, KAIA, not only symbolizes the merger of Klaytn and Finschia but also represents a commitment to partners and the community, intending to bring together developers, enterprises, users, and traders in a unified ecosystem.

The launch of Kaia signifies the rise of a network centered on collaboration, innovation, and users, which will simplify the user experience and promote the adoption and application of blockchain technology globally. Kaia's vision is to make blockchain technology accessible and widespread for everyone, regardless of their background or experience. This vision is guided by its core values—community, sustainability, and simplicity—which serve as guiding stars for Kaia in fostering partnerships, engaging deeply with the community, and driving blockchain adoption.

Kaia's network structure is divided into three logical subnetworks:

Ⅰ Core Unit Network (CCN): Composed of Core Units (CC) responsible for transaction validation, execution, and block creation.

II Endpoint Node Network (ENN): Composed of endpoint nodes (EN) that handle RPC API requests and process service chain data.

Ⅲ Service Chain Network (SCN): An auxiliary blockchain independently operated by dApp, connected to the main chain through EN.
