  • Founded: 2019, mainnet launched December 2022
  • Co-founders: Fabio Galdi (CEO) and Mariana Krym

Introduction

Vyvo Smart Chain (VSC) is a purpose-built Layer 1 blockchain designed to give individuals control over their personal health data. It bridges the gap between wearable IoT devices and the Web3 economy, enabling users to generate, own, and monetize their biometric information on-chain.

At the heart of the project is a HealthFi philosophy: the idea that people — not corporations — should own the value their health data creates.

History & Background

The VSC Foundation was established in 2019 by Fabio Galdi, a telecommunications and computer science veteran, and Mariana Krym, a digital media and blockchain strategist. Together they developed the concept of a decentralized health data blockchain.

The Vyvo Smart Chain mainnet officially launched in December 2022. In 2023, the project forged a strategic partnership with VeChain to reward users with B3TR tokens for healthy habits tracked via wearables.

How Vyvo Smart Chain Works

VSC uses a hybrid consensus model combining standard Proof-of-Stake (PoS) with a proprietary Proof-of-Sensing (PoSe) protocol. PoSe is the innovative layer: it validates health metric data generated by approved wearable devices and rewards users for contributing real-world biometric information to the network.

The chain is EVM-compatible, meaning it supports standard Ethereum tooling and smart contracts. This allows developers to deploy DeFi apps, NFTs, and custom dApps on top of the health data infrastructure.

Data assets are represented as Data-NFTs, turning personal health records into user-owned, on-chain tokens.

Tokenomics

VSC is the native utility token of the network. It serves three core functions: paying transaction gas fees, staking to run validator nodes, and rewarding users who contribute health data via PoSe.

The ecosystem also includes Vyvo Data Credits (VDC), which operate on a burn-and-mint equilibrium with VSC. When data is purchased on the platform, VSC is burned to mint VDC, creating a deflationary pressure tied to real data demand.

Ecosystem & Use Cases

  • inPersona App: The consumer-facing app connecting wearables, Data-NFTs, and reward programs.
  • BioSense Wearables: Hardware devices (Band and Ring) that capture biometric data and feed it to the blockchain.
  • VAI OS: An AI-powered Web3 operating system built on VSC infrastructure for decentralized data management and AI-driven personalization.
  • VeChain Integration: Users earn B3TR tokens via the inPersona Pro App for verified healthy lifestyle choices.

Team, Governance & Community

Fabio Galdi (CEO & Co-Founder) brings decades of experience in telecommunications and network marketing. Mariana Krym (Co-Founder & SVP of Blockchain Strategy) has a background in digital media, having advised major platforms including Waze, Twitter, and Spotify.

The project is governed by the VSC Foundation and maintains active community channels on Discord, Twitter, Medium, and YouTube.

Advantages

  • Data ownership: Users hold full control of their biometric data as on-chain NFTs.
  • Real-world utility: Wearable hardware creates genuine data supply for the blockchain.
  • EVM compatibility: Lowers the barrier for developers to build on the platform.
  • Multi-chain presence: VSC token is accessible on BNB Smart Chain and Polygon.
  • AI integration: VAI OS extends the ecosystem into AI-driven data services.

Risks & Challenges

  • Hardware dependency: Ecosystem growth is tied to adoption of proprietary wearable devices.
  • Reward program ended: The original HealthFi and DataFi reward distribution program concluded in early 2026 due to economic sustainability concerns.
  • Liquidity risk: VSC trading activity has been limited, making the token less liquid.
  • Regulatory exposure: Health data monetization faces evolving privacy and compliance requirements globally.

Long-Term Vision

Vyvo Smart Chain aims to position VSC as a foundational layer for both wearable technology and AI-driven data services. With the expansion into VAI OS, the project is pivoting toward a broader Web3 AI ecosystem where decentralized data management, privacy protection, and blockchain-based verification serve next-generation applications well beyond fitness tracking.

Frequently Asked Questions

Vyvo Smart Chain is a Layer 1 EVM-compatible blockchain designed for health data ownership and monetization. It rewards users for sharing biometric data generated by approved wearable devices through a mechanism called Proof-of-Sensing.

Proof-of-Sensing is a proprietary consensus protocol unique to VSC that validates health metric data from wearable IoT devices. It rewards users for contributing real biometric data to the network, sitting alongside standard Proof-of-Stake.

Data-NFTs are on-chain tokens that represent a user's personal health data on Vyvo Smart Chain. They give users verifiable ownership of their biometric records and allow that data to be managed or monetized in a privacy-preserving way.

inPersona is the consumer-facing application that connects Vyvo wearable devices, Data-NFTs, and the VSC reward ecosystem. Users keep their wearables linked to the app to participate in health data programs.

VSC was co-founded by Fabio Galdi, a computer science and telecommunications expert, and Mariana Krym, a digital media and blockchain strategist. The VSC Foundation was established in 2019 with the mainnet launching in December 2022.

VAI OS is an AI-powered Web3 operating system built on VSC infrastructure. It extends the ecosystem beyond health tracking into broader decentralized data management and AI-driven personalized services.

The VSC token is available as a cross-chain asset on BNB Smart Chain and Polygon, in addition to the native Vyvo Smart Chain mainnet. This multi-chain presence improves accessibility for users and traders.

The HealthFi and DataFi reward distribution program officially concluded in early 2026 due to economic sustainability concerns with the existing model. The underlying blockchain infrastructure and wearable platform services continue to operate.
