Kakao, the South Korean tech giant behind the wildly popular messaging app KakaoTalk—often compared to LINE in Taiwan—is making bold moves beyond instant messaging by deeply investing in blockchain technology. With the creation of its blockchain subsidiary GroundX, the launch of its high-performance public blockchain Klaytn, and the rollout of its crypto wallet Klip, Kakao is positioning itself as a major player in the global blockchain ecosystem.
This strategic expansion isn’t just about launching new products—it’s about building a decentralized digital economy that leverages Kakao’s existing user base of over 50 million while opening doors to international markets.
Building the Future: GroundX and the Vision Behind Klaytn
Kakao’s blockchain journey began in March 2018 when it announced plans to develop proprietary blockchain technology. That same year, the company established GroundX, a dedicated subsidiary tasked with creating and managing its blockchain infrastructure. The goal? To integrate blockchain services seamlessly with Kakao’s vast internet ecosystem, including social media, payments, gaming, and content platforms.
By October 2018, GroundX launched the Klaytn testnet, laying the foundation for what would become one of Asia’s most scalable enterprise-grade blockchains. According to the Klaytn Position Paper, the platform uses a hybrid consensus model combining Consensus Nodes (CNs) and Role Nodes (RNs) to balance decentralization, transparency, and performance.
One of Klaytn’s standout features is its lightning-fast block generation time—just one second, compared to Ethereum’s average of 15 seconds. This efficiency enables Klaytn to process up to 3,000 transactions per second (TPS), far surpassing Ethereum’s typical throughput of under 20 TPS.
“Klaytn achieves scalability without sacrificing user experience or security,” says a technical whitepaper released by GroundX. “It’s designed for real-world applications that demand speed and reliability.”
The mainnet officially went live on June 27, marking a major milestone in Kakao’s blockchain roadmap. To ensure network stability and incentivize participation, Klaytn introduced a unique reward mechanism called Proof of Contribution (PoC). Unlike traditional proof-of-stake or proof-of-work models, PoC evaluates the economic contributions of participants across the ecosystem—developers, service providers, validators—and rewards them with KLAY tokens, Klaytn’s native cryptocurrency.
Growing the Ecosystem: Partnerships and Real-World Adoption
GroundX didn’t stop at building fast infrastructure—it actively cultivated an ecosystem around Klaytn. In a private sale earlier in the year, the subsidiary raised $90 million, attracting investment from top-tier venture capital firms such as IDG Capital, Cresendo Equity Partners, and Translink Capital.
More importantly, Klaytn has formed strategic partnerships with 26 companies planning to deploy decentralized applications (dApps) on the network. Key collaborators include:
- Wemade, a leading South Korean video game developer known for its blockchain-integrated games.
- Watcha, a popular video streaming platform exploring tokenized content models.
- Zanadu, a Chinese travel tech company leveraging blockchain for loyalty programs and booking transparency.
Jason Han, CEO of GroundX, emphasized the transformative potential of token economics:
“Until now, Kakao operated primarily within Korea. But blockchain allows us to go global. By sharing value directly with users through tokens, we can create more inclusive and expansive markets.”
This vision aligns perfectly with Kakao’s broader strategy: turning passive users into active stakeholders in a decentralized digital economy.
Klip: Bridging Mass Users to Blockchain
To onboard millions of non-technical users, Kakao is launching Klip, a user-friendly cryptocurrency wallet designed for seamless integration with KakaoTalk. Klip will support KLAY tokens and allow users to interact with dApps directly from their messaging app—no complex setup required.
The wallet’s interface includes built-in access to partner dApps like Hintchain, a food traceability platform that uses blockchain to verify supply chain data. Users who engage with these services through Klip will earn additional crypto rewards—a gamified approach aimed at driving adoption.
With over 50 million monthly active users on KakaoTalk, even low engagement rates could translate into massive dApp usage on Klaytn. The company hopes Klip will become the gateway for mainstream audiences to explore decentralized finance (DeFi), NFTs, and Web3 services.

Developer Outreach: Hackathons and Global Expansion
Recognizing that developer adoption fuels long-term success, GroundX has launched initiatives to attract global talent. One notable example is the Klaytn Horizon Hackathon, offering prize pools of up to $1 million to teams building innovative solutions on Klaytn.
In addition, technical teams from Klaytn have begun engaging with international developer communities. A recent developer meetup in Taiwan—co-hosted by Dapp.com, ABM, and ABA—drew significant interest from regional builders. Attendees participated in workshops focused on Klaytn’s core strengths: high-speed transaction processing and superior dApp performance.
These outreach efforts signal Kakao’s intent to expand beyond Korea and compete with other blockchain platforms like Binance Smart Chain, Solana, and Polygon in the global Web3 race.
Frequently Asked Questions (FAQ)
Q: What is Klaytn?
A: Klaytn is a public blockchain developed by Kakao’s subsidiary GroundX. It's designed for enterprise and consumer applications, offering fast transaction speeds (1-second block time) and high throughput (up to 3,000 TPS).
Q: What is the role of KLAY tokens?
A: KLAY is the native cryptocurrency of the Klaytn network. It's used for transaction fees, staking, governance, and rewarding contributors through the Proof of Contribution (PoC) system.
Q: How does Klip work with KakaoTalk?
A: Klip is a crypto wallet integrated into KakaoTalk. Users can manage assets, connect to dApps, and earn rewards—all within the familiar messaging interface.
Q: Is Klaytn decentralized?
A: Klaytn uses a hybrid model—partly centralized for performance, but with transparent governance and incentives for node operators and developers to promote decentralization over time.
Q: Who are Klaytn’s main competitors?
A: Key competitors include Ethereum (especially post-upgrades), BNB Chain, Solana, and other high-performance blockchains targeting dApp developers and enterprises.
Q: Can developers build on Klaytn?
A: Yes. Klaytn supports Solidity-based smart contracts, making it compatible with Ethereum tools. Developers can deploy dApps easily and benefit from lower fees and faster confirmation times.
The Road Ahead
Kakao’s move into blockchain reflects a growing trend among tech giants: leveraging existing platforms to democratize access to decentralized technologies. While competitors like LINE are also entering this space—with their Bitbox exchange and LINK token ecosystem—Kakao’s integration of messaging + wallet + dApp access gives it a unique advantage.
As Web3 adoption accelerates, platforms that simplify user experience will lead the charge. With Klaytn’s speed, Klip’s accessibility, and GroundX’s aggressive ecosystem development, Kakao is well-positioned to become a cornerstone of Asia’s blockchain future.
