The Evolution of the Kaia Blockchain Ecosystem: On-chain Growth Model Centered on 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 two major internet giants, Kakao and LINE. Klaytn was launched in June 2019 by Kakao Group's subsidiary Ground X, with early alliance members including well-known South Korean companies such as LG Electronics and Celltrion. Finschia was initially launched by LINE in August 2018, and subsequently established a foundation in Abu Dhabi to oversee operations. In August 2024, the two chains will officially merge into the Kaia mainnet, which will be managed by the newly established Kaia DLT Foundation.

Kaia is positioned as a high-performance Layer 1 public blockchain focused on large-scale applications, featuring high TPS and developer-friendly characteristics. Its core advantage lies in its mature SDK ecosystem and deep integration with KakaoTalk and LINE platforms, supporting various decentralized applications to run directly on these mainstream social platforms. Kaia employs a BFT consensus mechanism, which has been highly optimized to achieve enterprise-level reliability and performance standards.

1.2 Main Features

Kaia adopts a layered node architecture, including core units, consensus nodes, proxy nodes, and endpoint nodes. The network uses an improved Byzantine fault-tolerant consensus algorithm to achieve a 1-second block time and instant finality, with a theoretical peak throughput of about 4000 TPS. Kaia is EVM compatible, supports Ethereum ecosystem smart contracts, and is integrated with various cross-chain bridges to enable asset interoperability.

Kaia closely integrates with the LINE ecosystem, allowing developers to deploy native Dapps directly within the chat application. In May 2025, Tether will issue native USDT on the Kaia Blockchain, providing users with stablecoin payment and cross-border transfer services. Kaia adopts a sustainable token economic model, with the native token KAIA used for paying transaction fees and incentivizing network operations.

2. Progress of Ecological Construction

2.1 Kaia Wave plan and Mini Dapp ecosystem

After the launch of the Kaia mainnet in August 2024, the Kaia Wave plan will be released simultaneously, enabling Web3 developers to build Mini Dapps for LINE users through the SDK developed by LINE NEXT. The first batch of Mini Dapp projects will go live in LINE Messenger in the first quarter of 2025. Kaia has also jointly launched a Mini Dapp growth competition with the LINE Dapp Portal to continuously drive accelerated growth of the ecosystem.

2.2 Kaia Stablecoin plan

In May 2025, Kaia partnered with Tether to issue USDT natively on-chain. This native USDT is fully deployed in contract form on the Kaia network and is directly hosted and issued by Tether. The first batch of native USDT has been integrated into the Mini Dapp ecosystem within LINE Messenger, enabling the everyday use of stablecoins. Several major exchanges have also successively supported USDT-KAIA network.

2.3 Ecological investment progress

In April 2025, the Kaia Foundation announced that it has secured funding led by 1kx and Blockchain Capital, with participation from well-known institutions such as Galaxy Digital and IDG Capital. This investment will provide Kaia with in-depth support in areas such as international market expansion, compliance framework construction, and ecological cooperative networks.

2.4 ecological strategic cooperation

Kaia continues to expand its strategic cooperation in dimensions such as data visualization, secure custody, and asset circulation. This mainly includes integration with Dune for on-chain data analysis, collaboration with Fireblocks to provide asset custody, establishing a strategic partnership with KuCoin, and working with Republic to provide advisory support for Mini Dapp developers.

2.5 Developer Support and Community Building

Kaia enhances the developer experience and stimulates community vitality through tools such as content incentives and educational promotion. This includes hosting lectures and training courses, launching a content creation rewards program, releasing the DEX Scanner feature, opening developer boot camps, and launching the Kaia Agent Kit development suite.

3. Excellent Project Cases of Kaia Ecosystem

3.1 Excellent projects that have completed TGE
