🔍 Introducing OpenVulnScan & VulnChain: An Open and Incentivized Approach to Vulnerability Management

In a world where software is eating the world, vulnerabilities are multiplying just as fast. Security teams everywhere are stretched thin trying to keep up with identifying, classifying, and remediating vulnerabilities in their environments. Traditional vulnerability management tools are often expensive, closed-source, and disconnected from the growing community of ethical hackers, researchers, and open-source developers. That’s where OpenVulnScan and VulnChain come in.

🧩 What is OpenVulnScan?

OpenVulnScan is a modern, open-source vulnerability management tool designed for security professionals, developers, and DevSecOps teams who want transparency, extensibility, and simplicity.

🔧 Core Features:

• 🖥️ Agent-based Package Reporting: Lightweight agents report installed packages from Linux systems.

• 🔎 Nmap-based Unauthenticated Scanning: Automatically scan networked hosts for open ports and known CVEs.

• 📚 Integrated CVE Lookup: Correlates reported packages and scan data with a live CVE database.

• 🔐 OAuth2 & Wallet Authentication: Supports Google/GitHub sign-ins and decentralized wallet-based auth.

• 📊 Dashboard & Reports: View HTML reports of vulnerabilities per agent, system, or package.

• 📡 REST API First: Everything runs on an extensible FastAPI backend for integration or API-first deployments.

It’s designed to be lightweight enough for small teams and powerful enough to integrate into CI/CD pipelines.

🔗 What is VulnChain?

VulnChain builds on the foundation of OpenVulnScan by introducing token-based incentives and blockchain-backed transparency to vulnerability management.

🚀 The Vision:

Think of VulnChain as the “bug bounty meets open vulnerability intel” network. It’s a decentralized network where:

• Researchers can submit CVE data or package signatures to help the community.

• Agents can report findings from systems in real-time.

• Submissions are timestamped, indexed on-chain, and accessible for trustless verification.

• Contributors are rewarded with tokens for actionable and validated data.

• Everything is auditable, exportable, and designed for global collaboration.

🛠️ Built With:

• 🪙 Cardano (via Blockfrost) for decentralized storage of report hashes and contributor reputations.

• 📁 IPFS for off-chain storage of vulnerability reports.

• 🔐 JWT / Wallet auth for identifying contributors and reward recipients.

• 📊 OpenVulnScan’s API for real-time data intake.
