Kaia is a high-performance, EVM-compatible Layer 1 blockchain born from the merger of Klaytn (Kakao Corp’s blockchain) and Finschia (LINE Corporation’s blockchain) — giving it a unique distribution pathway through two of Asia’s largest messaging platforms, combined reaching over 200 million active users in South Korea, Japan, Thailand, and beyond. Originally launched as Klaytn in 2019, the chain was rebranded to Kaia in 2024 following the merger with Finschia. With sub-second finality, low fees, and deep integration in Kakao’s KakaoTalk and LINE’s messaging ecosystem, Kaia is positioned as a “Web2-to-Web3 on-ramp” for Asia’s massive internet user base. KAIA is the native gas and staking token.

How It Works
Istanbul BFT consensus:
Kaia uses a Byzantine Fault Tolerant consensus where a set of 50 publicly elected Council Nodes validate transactions. All nodes participate in voting each block, achieving 1-second finality with no fork risk — ideal for consumer payment applications.
Node hierarchy:
- Governance Council — 50 elected validator nodes run by major institutions (exchanges, corporates)
- Proxy Nodes — relay transactions between endpoints and consensus nodes
- Endpoint Nodes — serve dApps and wallets
Kakao and LINE integrations:
KakaoTalk users can send KAIA via the app’s digital wallet. LINE users can interact with Kaia-based dApps through LINE mini-apps. These integrations create a Web2 user experience for blockchain transactions.
EVM compatibility:
Kaia is EVM-compatible — Solidity contracts deploy directly, making it easy to port Ethereum DeFi and NFT projects.
Tokenomics
| Metric | Value |
|---|---|
| Supply | Inflationary — newly minted each block |
| Block rewards | Distributed to Governance Council stakers |
| Burn mechanism | % of fees burned; Kaia actively targets reduced inflation |
| KLAY→KAIA conversion | 1 KLAY = 1 KAIA (post-merger) |
| Reserve funds | Klaytn Foundation + Finschia Foundation merged into Kaia Foundation |
Use Cases
- Gas — KAIA pays transaction fees on Kaia blockchain
- Staking — Delegating to Governance Council nodes earns rewards
- KakaoTalk / LINE payments — KAIA integrated in consumer messenger apps
- NFT ecosystems — Active NFT marketplaces and gaming dApps
- DeFi — Growing DeFi ecosystem on an EVM chain with institutional node backing
History
- Jun 2019 — Klaytn mainnet launches (by Ground X / Kakao Corp)
- 2020–2022 — Klaytn grows as Korea’s dominant L1; enterprise partnerships with Samsung, LG, Hyundai
- 2022 — Finschia (LINE’s blockchain, formerly LINK) launches; competing Asian chain from Japan
- 2023 — Klaytn and Finschia foundations announce merger to form unified Kaia chain
- 2024 — Kaia mainnet goes live; KLAY and FNSA tokens migrate to KAIA; unified Kakao + LINE ecosystem
- 2024 — Kaia Foundation continues expanding Southeast Asian reach
Common Misconceptions
“Kaia is a Korean-only project.” While Kakao is Korean and LINE is Japanese, their reach spans all of Southeast Asia — Thailand, Indonesia, Taiwan. Kaia is targeting all of Asia’s messaging-app-native users.
“Klaytn was just an enterprise chain.” Klaytn supported enterprise pilots, but its public DeFi and NFT ecosystems were substantial. After the Kaia rebrand, consumer focus and public DeFi have intensified.
