Kaia Ecosystem Evolution: On-Chain Growth Paradigm Centered Around Mini Dapp

1. Overview of the Kaia Blockchain Ecosystem

1.1 Origin and Team Background

Kaia is a new ecosystem formed by the merger of the blockchain projects Klaytn and Finschia, led by the two tech giants Kakao and LINE. Klaytn was launched in June 2019 by Ground X, a blockchain subsidiary of the Kakao Group, with early governance alliances including renowned South Korean companies like LG Electronics, Celltrion, and Netmarble. Finschia was introduced by LINE in August 2018 through its blockchain subsidiary LINE TECH PLUS and was renamed in 2022. In August 2024, the two chains officially merged, launching the new Kaia mainnet, which is managed by the newly established Kaia DLT Foundation.

Kaia aims to be an L1 blockchain focused on large-scale applications, featuring high TPS and developer-friendly characteristics. Its core advantage lies in a mature SDK system and deep integration with KakaoTalk and LINE platforms, supporting various decentralized applications to run directly on these mainstream social platforms. As a public blockchain based on BFT consensus mechanism, Kaia has been highly optimized, striving to achieve enterprise-level reliability and performance standards, providing solid underlying support for the next generation of Web3 applications.

1.2 Important Development History

• June 2019: Ground X launched the Klaytn mainnet
• December 2022: LINE launched the Finschia mainnet
• April 2023: LINE established the Abu Dhabi Finschia Foundation
• August 2024: Kakao and LINE jointly launch the Kaia mainnet
• April 2025: The Kaia Foundation secures funding led by 1kx and Blockchain Capital.
• May 2025: Tether issues USDT on the Kaia chain.

1.3 Main Features

Kaia adopts a hierarchical node architecture and utilizes an improved Byzantine Fault Tolerance consensus algorithm. The network achieves a block time of 1 second and instant finality, with a theoretical peak throughput of about 4000 TPS. Kaia is compatible with EVM, supports smart contracts in the Ethereum ecosystem, and integrates with various cross-chain bridges. Kaia closely connects with the LINE instant messaging ecosystem, allowing developers to directly deploy native Dapps within the chat application by providing SDK/API.

Kaia adopts a sustainable token economic model: its native token KAIA is used to pay transaction fees and incentivize network operations. Kaia supports on-chain governance, allowing annual inflation rates and fee models to be adjusted based on community resolutions. Compared to other mainstream public chains, Kaia has significantly differentiated features: it focuses on the Asian market, bringing Kakao and LINE's massive user base into the Web3 ecosystem; technologically, it employs a second-level finality consensus algorithm; ecologically, it quickly integrates key assets like stablecoins.

2. Progress of Ecological Construction

2.1 Kaia Wave Plan and Mini Dapp Ecosystem

In August 2024, the Kaia mainnet will launch and release the Kaia Wave program, aimed at enabling Web3 developers to build Mini Dapps for LINE Messenger users through the NEXT WEB SDK developed by LINE NEXT. The first batch of Mini Dapp projects will go live in the first quarter of 2025, covering multiple niche tracks. Kaia, in collaboration with the LINE Dapp Portal, will initiate the Mini Dapp Growth Competition to continuously drive ecosystem acceleration and rise.

2.2 Kaia Stablecoin plan

In May 2025, Kaia partnered with Tether to issue USDT natively on-chain. The native USDT has been integrated into the Mini Dapp ecosystem within LINE Messenger, allowing users to complete payments, transfers, and DeFi activities directly in the LINE environment. Multiple mainstream exchanges have supported the USDT-KAIA network. The Kaia team is promoting the issuance plan of the Korean won stablecoin and plans to launch a series of on-chain financial products and services.

2.3 ecological investment progress

In April 2025, the Kaia Foundation secured funding led by 1kx and Blockchain Capital, with participation from Galaxy Digital, The Spartan Group, IDG Capital, among others. This collaboration will help promote the market for LINE NEXT and Mini Dapp services, and strengthen Kaia's influence in the global market.

2.4 ecological strategic cooperation

Kaia continues to expand its strategic partnerships in data visualization, secure custody, asset circulation, scenario implementation, and financial support, establishing collaborations with Dune, Fireblocks, KuCoin, Republic, MEXC, Travala, Team Finance, and others.

2.5 Developer Support and Community Building

Kaia enhances the developer experience and stimulates community vitality through tools, content incentives, and educational promotions. Key initiatives include organizing lectures and training courses, launching a content creation reward program, releasing the DEX Scanner feature, opening a developer training camp, and introducing the Kaia Agent Kit development suite.
