Klaytn
Kaia is an EVM-compatible Layer 1 public blockchain designed to bring Web3 to millions of users across Asia with fast finality and seamless user experiences.
Overview
Kaia is a public Layer 1 blockchain built to deliver a fast, interoperable, and user-friendly Web3 experience primarily targeting the Asian market. It emerged from the merger of the Klaytn and Finschia blockchains, originally developed by Kakao and LINE, respectively. Kaia supports Ethereum Virtual Machine (EVM) compatibility, enabling developers to deploy Solidity smart contracts with minimal changes. It also plans to support CosmWasm for additional flexibility. The network boasts a 1-second block time with immediate finality, making it one of the fastest EVM Layer 1 blockchains, which supports use cases requiring near real-time responsiveness.
Kaia’s architecture includes features such as account abstraction and gas fee delegation, which simplify onboarding and reduce friction for end users. Integration with popular messenger apps like LINE and KakaoTalk provides developers instant access to over 250 million users, facilitating mass adoption. The network is a hard fork and rebrand of the Klaytn mainnet, ensuring backward compatibility and a smooth transition for existing projects. Kaia supports batching of RPC requests with a default limit of 3,000, which is configurable, enhancing performance for node operators and developers.
Developers can get started quickly using the Kaia SDK and comprehensive documentation available at docs.kaia.io. The ecosystem supports a wide range of applications including decentralized finance (DeFi), gaming, and real-world asset (RWA) tokenization. Kaia also offers grants, bounties, and hackathons to encourage developer participation. Node operators can run various node types such as consensus nodes, proxy nodes, and endpoint nodes, with detailed operation guides provided. The open-source codebase is primarily written in Go and licensed under LGPL and GPL licenses. Kaia’s governance is community-driven through Kaia Square and governance forums, promoting decentralized decision-making.
Overall, Kaia aims to be a scalable, developer-friendly blockchain platform that bridges Web3 to mainstream users in Asia, combining high performance with seamless user experiences and broad ecosystem support.
