Kaia

Kaia is an Ethereum-equivalent Layer 1 blockchain formed from the merger of Klaytn, developed by South Korea's Kakao, and Finschia, developed by Japan's LINE. That combination gave the network distribution through two of Asia's largest messaging platforms, and the project's stated focus is bringing blockchain applications to users through those messenger superapps.

How Kaia works

The network uses Practical Byzantine Fault Tolerance, an optimised BFT consensus that produces one second block times with immediate absolute finality. Immediate finality means a transaction is irreversible as soon as it is included in a block, rather than becoming progressively more secure over subsequent blocks as in probabilistic systems. The project reports throughput of around 4,000 transactions per second in real-world conditions. Kaia is Ethereum-equivalent, so Solidity contracts and standard Ethereum tooling work on it directly.

KAIA has no published maximum supply cap in the available data. Total supply is approximately 6.39 billion tokens, with essentially all of that in circulation. The token pays for transaction fees and secures the network through staking by validators.

Role in the ecosystem

Kaia's distinguishing feature is distribution rather than technology. Access through Kakao Talk and LINE places blockchain applications in front of a very large combined user base across South Korea, Japan, Taiwan, and Thailand. The network has focused on mini-apps and consumer-facing use cases delivered inside those messengers, an approach closer to Telegram's TON ecosystem than to developer-first Layer 1 chains. The merger that created Kaia also consolidated two separate developer ecosystems and token supplies into one network, which is unusual in an industry where chains more often fragment than combine. That consolidation gave the resulting network a larger combined developer base and treasury than either predecessor had on its own.
