### What is Kaia (KAIA)?

Kaia is the native cryptocurrency and utility token of the Kaia blockchain, a high-performance Layer 1 public blockchain. Launched officially on 29 August 2024, Kaia was formed through the merger of two major Asian blockchain projects: Finschia (by LINE) and Klaytn (by Kakao). KAIA is used to pay transaction fees, execute smart contracts, and incentivise network participants.

Kaia distinguishes itself with unique features such as EVM compatibility, rapid transaction speeds (4,000 TPS), 1-second finality, low gas fees (approximately one-tenth of Ethereum), and a modular three-layer network architecture designed for scalability and enterprise-grade reliability. Its overarching goal is to accelerate blockchain mass adoption by offering a scalable, interoperable, and efficient platform suited for both consumer and enterprise use.

### How does Kaia (KAIA) work?

#### Underlying Technology

Kaia operates as a Layer 1 EVM-compatible blockchain, integrating the strengths of Finschia and Klaytn. Its modular architecture consists of:

- **Core Cell Network**: Handles transaction processing.
- **Endpoint Node Network**: Provides API access and service chain connections.
- **Service Chain Network**: Supports independent dApps and specialised applications.

The Kaia Virtual Machine (KVM) ensures compatibility with Ethereum, enabling smooth migration of Ethereum-based smart contracts and secure cross-chain operations.

#### Consensus Mechanism

Kaia employs a modified **Istanbul Byzantine Fault Tolerance (IBFT)** consensus mechanism, enhanced with **Verifiable Random Function (VRF)**-based randomness and committee-based validator selection. This setup allows for 1-second block generation and instant finality.

#### Algorithms

- Modified Istanbul BFT (IBFT) with VRF-based randomness.
- Practical Byzantine Fault Tolerance (pBFT) optimisations for high throughput.

#### Smart Contracts

Kaia supports smart contract deployment via its EVM-compatible KVM, enabling developers to port existing Ethereum dApps or build new decentralised applications on the Kaia network.

### What are the potential use cases for Kaia (KAIA)?

#### Applications

- Paying transaction fees and executing smart contracts on the Kaia network.
- Real-world asset (RWA) DeFi, including tokenisation of agricultural and supply chain data.
- Decentralised exchanges (DEXs), liquid staking, lending, and yield aggregators (e.g., DragonSwap, Stake.ly, KlayBank).
- AI-driven global trade facilitation, particularly in agriculture.
- NFTs, gaming, and data-driven decentralised applications.

#### Industries

- **Agriculture and food supply chain**: Smart farming, data management, and traceability.
- **Finance and DeFi**: Payments, lending, staking, and yield aggregation.
- **Enterprise and public sector**: Identity solutions, data transparency, and cross-chain integrations.

#### Partnerships

The Kaia Foundation has partnered with CARV to bolster identity and data privacy infrastructure. Integration with Dune Analytics supports ecosystem data visibility. Leveraging the established user bases of Kakao and LINE, Kaia focuses on driving mass adoption, particularly in East Asia.

### What is the history of Kaia (KAIA)?

#### Origin

Kaia emerged from the merger of two established blockchains: Finschia (launched by LINE in 2018) and Klaytn (developed by Kakao’s Ground X in 2019). The unification combined their technologies, communities, and governance models, culminating in the Kaia mainnet launch on 29 August 2024.

#### Milestones

- Kaia mainnet launch (29 August 2024).
- Introduction of EVM compatibility and a modular network design.
- Listing on major exchanges and rapid ecosystem growth encompassing DeFi and NFT projects.

#### Major Updates or Forks

The formation of Kaia through the merger represents its most significant development to date. No major forks have occurred since its inception.

#### Technology and Market Evolution

Kaia has developed into a high-throughput, low-fee, enterprise-ready blockchain. Its ecosystem now includes a growing range of DeFi, NFT, and real-world asset projects. As of June 2025, KAIA has a circulating supply near 6 billion tokens, with a market capitalisation exceeding $500 million.
