KardiaChain is a Layer-1 blockchain purposefully crafted to bridge the divide between blockchain technology and its mainstream adoption by merging the physical and digital realms. As a hybrid public-private blockchain infrastructure, KardiaChain emphasizes decentralization, security, and scalability to provide seamless Web3 solutions for real-world applications. It also supports transformative technologies such as Onchain AI and NF3 Chip Technology to further enhance its ecosystem. Key Features: High Performance and Scalability - Employs the Byzantine Fault Tolerance Delegated Proof-of-Stake (BFT-DPoS) consensus mechanism to achieve high throughput, low latency, and energy-efficient operations. - Engineered to scale while preserving decentralization and minimizing transaction costs. Hybrid Blockchain Model - Integrates public and private chains to offer enhanced privacy, security, and flexibility suited for both enterprise and consumer use cases. Phygital Integration (Kyokai Initiative) - Translates real-world elements—People, Items, Locations, and Activities (P.I.L.A.)—onto the blockchain utilizing technologies such as NFC+, AR/VR, and 3D modeling. - Allows for trackable and verifiable physical items, including luxury goods, events, and spaces. - Links physical assets to on-chain representations for ownership, authentication, and interactive experiences. Onchain AI Integration KardiaChain drives Onchain AI, a platform that combines artificial intelligence with blockchain technology. Key features include: - AI Agents: Autonomous agents proficient in managing social media interactions, handling blockchain wallets, and automating digital tasks. - On-Chain Recording: Ensures all actions are securely recorded on the blockchain for complete transparency and accountability. - Token Utility: AI agents use energy from burning $KAI, promoting sustainable tokenomics. - Upcoming Features: Voice-based AI interactions, media creation, and live streaming. Onchain AI enables AI-driven virtual agents that oversee online identities and interactions with capabilities such as: - Automating social media engagement, content creation, and audience interaction. - Managing blockchain-based wallets with secure and transparent operations. - Monetization Opportunities: Users can earn based on engagement metrics, nurturing a revenue-generating ecosystem. - Skillset Marketplace: Agents can acquire and trade advanced skillsets, including trading, content creation, and music composing. NF3 Chip Technology A phygital bridge using NFC (Near-Field Communication) chips to integrate physical objects with blockchain-based digital assets. Key functionalities include: - Encrypted Private Keys: Ensures secure ownership validation and asset transfers. - Phone Number-Based Wallets (PNW): Simplifies onboarding and wallet management. - Interactive Phygital Experiences: Enables seamless real-world-to-digital interactions via simple NFC taps. - Use Cases: Digital gifting, product verification, collectibles, and consumer engagement. Web3 Infrastructure and Ecosystem - Offers a comprehensive toolset, including wallets, explorers, smart contract IDEs, NFT creation platforms, and analytics tools. The platform operates on its native token, KAI, which is used for staking, transaction fees, service participation, and smart contract deployment. KardiaChain was initially announced in October 2018, with its mainnet launch occurring in December 2020.

KardiaChain was established by Tri Pham and Huy Nguyen, who were high-school classmates. Pham serves as the CEO, while Nguyen holds the position of Chief Technology Officer. Pham is a seasoned entrepreneur; prior to KardiaChain, he co-founded AppFluke, a startup dedicated to bridging the gap between advanced technology and consumer products. Pham credits his experience at AppFluke with sparking his interest in making new technology accessible to the public. In 2017, he recognized the immense potential of blockchain technology. Partnering with Nguyen, he concentrated on the Vietnamese market and introduced KardiaChain as a solution for blockchain interoperability with an enterprise focus. Nguyen previously held the position of Technical Manager at Google, where he led the Google Fiber project. Several other team members from Google also joined KardiaChain, contributing to its core development team. Nguyen's experience includes technical engineering roles at Cisco, Apple, and Hitachi.

KardiaChain distinguishes itself as a Layer-1 blockchain adept at integrating real-world applications with blockchain technology, positioning it as a pioneer in phygital innovation. In contrast to traditional blockchains, KardiaChain's hybrid public-private model provides flexibility, scalability, and security for both enterprises and users. Empowering advanced technologies such as Onchain AI for AI-driven automation and AI agents, as well as NF3 Chip Technology for connecting physical assets to the digital realm, KardiaChain fosters a dynamic ecosystem that unites Web3, AI, and tangible utility.

KardiaChain's total token supply amounts to 5 billion KAI. From this supply, 816 million KAI (16.32%) was allocated for private sales, while 750 million KAI (15%) was made available during an initial exchange offering on Gate.io. Of the total supply, 1 billion KAI (20%) was reserved for the ecosystem, with 10% available immediately and the remaining 10% subjected to lock-ups. Additionally, 250 million KAI (5%) were designated for the community, with a 3-month lock-up period in place. Furthermore, 500 million KAI (10%) were allocated for block rewards, which are scheduled for release over a span of 10 years. The KardiaChain team received an allocation of 600 million KAI (12%), while its advisors were granted 150 million KAI (3%). Additionally, 934 million KAI (18.68%) were retained for foundation reserves. All these allocations were subject to a 12-month lock-up and a 24-month vesting period. Initially, KAI was issued as an ERC-20 token on the Ethereum blockchain but was later swapped for a token native to the KardiaChain blockchain following its mainnet launch.

The KardiaChain network employs a Byzantine Fault Tolerance delegated proof-of-stake consensus mechanism. This requires that new blocks added to the blockchain receive approval from a two-thirds majority, while stakeholders have the ability to delegate transaction validation responsibilities to trusted third parties. As outlined in its white paper, KardiaChain utilizes a dual-node approach to interoperability, ensuring that the security of other blockchains remains uncompromised when interfacing with KardiaChain. In December 2020, just prior to the launch of the KardiaChain mainnet, blockchain security firm CertiK conducted an audit. The audit concluded that "all the issues identified within the scope of the audit were formally addressed by the team."

KardiaChain (KAI) is available for purchase on various cryptocurrency exchanges, such as Coinstore, KuCoin, and Gate.io. For further information, refer to Eulerpool.
