1. Introduction

1.1 Vision & Mission of Hippo Protocol

Healthcare data is one of the most valuable yet fragmented and underutilized assets in the digital economy. Patients, healthcare providers, and researchers struggle with inefficiencies caused by data silos, regulatory restrictions, and privacy concerns, while centralized entities continue to hold control over sensitive health information.

Hippo Protocol is a Layer 1 blockchain designed to address these challenges by empowering patients, decentralizing data ownership, and enabling secure and compliant data transactions for healthcare and AI applications. By integrating privacy-preserving cryptographic models, decentralized identity (DID), and scalable data storage & computation, Hippo Protocol is revolutionizing the way healthcare data is managed, shared, and monetized in the Web3 era.

Our mission is to create a global decentralized healthcare data network where individuals and institutions can securely interact, exchange insights, and drive AI-powered innovation without compromising privacy, security, or regulatory compliance.

1.2 The Need for a Dedicated Healthcare Blockchain

Since its rebranding in 2023, Hippocrat has been committed to transforming healthcare data usage through decentralization and patient empowerment. Over the years, we have built a strong network of over 4 million+ unique health check-up recipients, 1.4 million of whom renew their data annually. We have partnered with industry leaders, including Saluscare (Korea’s #1 B2B health check solution provider), Ever Medical Technologies (the fastest growing EMR service in the emerging markets), Saint Mary’s Hospital, and Asan Medical Institute, to create a trusted ecosystem for healthcare data exchange.

However, existing blockchain infrastructure poses critical limitations that hinder scalability, usability, and compliance for healthcare applications. Some of the primary challenges include:

• High Transaction Costs

• Lack of Customization for Healthcare Data Needs

• Data Storage & Processing Bottlenecks

• Regulatory & Privacy Barriers

• Complexity of Blockchain for Non-Crypto Users

To overcome these limitations, Hippo Protocol strives to achieve Chain Abstraction, ensuring users can interact with the protocol without needing to understand blockchain or cryptocurrency mechanics. Healthcare providers and patients can seamlessly use Hippo Protocol like any other application, with blockchain complexities—including wallet management, transaction signing, and gas fees— fully abstracted from the user experience..

1.3 How Hippo Protocol Solves These Challenges

Hippo Protocol is designed to be a healthcare-optimized Layer 1 blockchain, incorporating solutions for privacy, compliance, interoperability, and decentralized computing. The protocol leverages chain abstraction, decentralized storage, zero-knowledge proofs (ZK-Proofs), secure AI computations, and compliant data handling mechanisms. More details on these innovations are covered in the Technical Overview section.

1.4 The Future of Healthcare Data with Hippo Protocol

With millions of users ready to onboard, global partnerships in motion, and cutting-edge AI-powered applications under development, Hippo Protocol is set to become the foundational blockchain for healthcare data exchange and AI research.

By leveraging privacy-preserving AI, decentralized computing, and scalable blockchain technology, Hippo Protocol enables:

• Patients to have sovereign control over their healthcare data.

• Healthcare providers & AI researchers to access compliant and high-quality datasets for innovation.

• Validators and Hippo Data Nodes to earn incentives while securing the decentralized healthcare data ecosystem.

As we move toward mainnet launch, we invite developers, healthcare institutions, AI researchers, and the Web3 community to join Hippo Protocol in shaping the future of decentralized healthcare data.

1.5 Key Benefits of Hippo Protocol

• Data Sovereignty: Patients gain full control over their health data, eliminating reliance on centralized entities.

• Interoperability: Seamless data exchange between healthcare providers, researchers, and patients while ensuring privacy and security.

• Low-Cost Transactions: Optimized microtransactions enable efficient, real-time data transfers.

• Decentralized Governance: A community-driven network where validators and ecosystem stakeholders influence decision-making.

• Enhanced Security & Compliance: Built-in features such as zero-knowledge proofs (ZK proofs) and HL7/FHIR compliance for secure, regulation-ready data handling.

With millions of users poised to join the ecosystem, Hippo Protocol represents a critical step in redefining how healthcare data is managed, shared, and monetized in the Web3 era.
