What Is Kaia Blockchain: Asia’s Most Promising Layer-1 Backed by LINE

What is Kaia blockchain? It is a "Web3 superhighway" – a public blockchain platform designed to be as simple as messaging, as fast as lightning, and as easy to access for everyone, even for those who have never touched blockchain before. Imagine: if you can send a message via LINE in just one second, now you can also send NFTs, tokens, or join a dApp with the same speed – while still maintaining decentralization, transparency, and security.

Backed by tech giants Kakao and LINE, Kaia blockchain is the result of a groundbreaking merger between two of the largest blockchain ecosystems in South Korea and Japan – Klaytn and Finschia – in 2024. With a powerful Layer-1 architecture, high scalability, and full support for DeFi, gaming, NFTs, and Web3 applications, Kaia chain is rapidly expanding into key markets like Japan, South Korea, Vietnam, and Indonesia.

Keep following this article to explore how Kaia works, what makes it different, and why it is becoming the most popular Web3 platform in Asia’s new era.

What Is Kaia Blockchain and How Did It Start?

How Did Kakao and LINE Merge to Create Kaia Blockchain?

Kaia blockchain is the product of a rare merger between two major tech corporations: Kakao (operator of the Klaytn platform) and LINE (under Naver, running the Finschia blockchain). The merger agreement was announced in February 2024 and completed in June 2024, leading to the formation of Project Dragon, under the unified brand Kaia.

The headquarters managing Kaia blockchain is located in Abu Dhabi, UAE – a jurisdiction known for clear and Web3-friendly regulations. Meanwhile, its operations staff are globally distributed: South Korea, Japan, Singapore. This move allows Kaia to maintain global reach and leverage the existing user networks of KakaoTalk and LINE – the two biggest messaging apps in East Asia.

With a combined market value of over 1.3 trillion KRW (~940 million USD), the union of Klaytn and Finschia positions Kaia blockchain as the largest Layer-1 asset-scale platform in Asia today.

What Is the Goal of Kaia Blockchain in 2025?

What is Kaia blockchain if it cannot serve the real world? In 2025, the goal of Kaia blockchain is to accelerate real-world adoption through open architecture, easy accessibility, and extremely low operational costs. It is a platform aimed at end-users – people who don’t need to know they’re using blockchain, yet still enjoy seamless Web3 utilities.

Kaia chain fully supports EVM (Ethereum Virtual Machine), compatible with familiar tools like Solidity, Remix, Foundry, enabling developers to deploy dApps in just minutes. Kaia’s gas fees are 10x lower than Ethereum, with confirmation time at just 1 second, delivering a Web2-like experience on Web3 infrastructure.

Key Features and Architecture of Kaia Blockchain

1. Layer-1 Infrastructure and EVM Compatibility

With 1-second block times, processing capacity of 4,000 transactions per second (TPS), and ultra-low gas fees, Kaia blockchain delivers performance sufficient to serve millions of users concurrently. This is crucial for making Web3 applications more practical in commerce, gaming, and finance.

Additionally, Kaia chain is fully EVM-compatible, allowing smart contracts written in Solidity to run smoothly on platforms like Remix, Hardhat, and Foundry. This helps developers from the Ethereum ecosystem easily migrate without rewriting entire codebases.

2. Multinetwork Design: CCN, ENN, SCN

One of the technical innovations of Kaia blockchain is its three-layer network structure:

• CCN (Core Cell Network): Composed of Core Cells responsible for transaction processing, validation, and block generation.
• ENN (Endpoint Node Network): Interfaces with Web3 apps via RPC, serving end-users and dApps.
• SCN (Service Chain Network): Independent sub-chains operated by each dApp, connected to the main chain through EN.

Network nodes include:

• CN (Consensus Node): Participates in block generation and consensus.
• PN (Proxy Node): Transmits transactions and blocks within the network.
• EN (Endpoint Node): Receives requests from apps or users.
• Bootnode: A special node that supports new nodes joining the network.

3. Consensus Mechanism: Optimized BFT

Kaia uses a customized version of Istanbul BFT (IBFT), combined with VRF (Verifiable Random Function) and PBFT (Practical Byzantine Fault Tolerance), ensuring fast, secure, and tamper-resistant consensus.

The consensus process includes:

• Randomly selecting a block proposer and validators via VRF.
• Block creation and broadcasting.
• Validators signing off (more than 2/3 approval) to finalize the block.
• Using separate multithreaded channels for data and blocks to reduce network congestion.

This mechanism enables Kaia blockchain to achieve near-instant finality – transactions become irreversible once confirmed, ensuring high reliability.
