Kaia (KAIA) is a Layer 1 public blockchain formed by merging Klaytn, started by Kakao affiliate Ground X, and Finschia, developed within the LINE ecosystem. A governance vote approved the merger in early 2024, and the unified mainnet launched on August 29, 2024.
The project aims to bring Web3 services to users across Asia through the messenger apps they already use. Existing KLAY and FNSA holders could convert their tokens into KAIA at predefined ratios.
Kaia uses a highly optimized form of Practical Byzantine Fault Tolerance (pBFT) consensus, delivering roughly one-second block times with immediate finality. It is designed to handle about 4,000 transactions per second in real-world conditions.
The chain is Ethereum-equivalent, so developers can reuse familiar Ethereum tools and smart contracts with little change. This combination supports fast transactions and makes it easier to migrate existing applications.

KAIA is the native token used for transaction fees, validator rewards, and governance participation. Ecosystem funds and foundation policies are set out in official documentation and governance decisions.
Mini dApps running inside Kakao Talk and LINE, stablecoin partnerships, and new financial products are key parts of the ecosystem. In 2026 the focus has been on infrastructure such as a won-pegged stablecoin initiative and institutional-grade financial products.
Links to major messenger platforms give Kaia access to a large potential user base, and its fast finality and Ethereum compatibility are often cited as strengths. The merger of two chains also created a sizable Asia-focused ecosystem.
Risks include reliance on partnerships with specific corporate platforms, questions about how decentralized its validator set is, and changing regulations across countries. Crypto assets can be highly volatile, so readers should verify information independently.
