Open Arsenal

The Open Ledger for Public Medicine

GrantChain is a public accountability and research intelligence platform designed to track the journey of taxpayer-funded medical discoveries from federally funded universities to pharmaceutical companies and, ultimately, to consumers. By connecting federal research grants, university discoveries, scientific publications, patents, intellectual property transfers, licensing agreements, and pharmaceutical commercialization, GrantChain creates a comprehensive, searchable record of how publicly funded medical innovation becomes privately commercialized. The platform integrates information from federal agencies, research institutions, patent databases, FDA records, and other public sources to establish traceable relationships between public investment and commercial medical products.

GrantChain uses artificial intelligence to continuously identify and map relationships between medical discoveries, pharmaceutical companies, corporate ownership, manufacturers, medications, and pharmacy sales. Its intelligent research engine analyzes patent assignments, licensing arrangements, drug approvals, pricing histories, and publicly available pharmaceutical revenue information. Users can upload prescription receipts as photographs or documents, allowing AI-powered OCR to extract medication names, dosages, purchase dates, pharmacies, and prices paid. These submissions contribute to an expanding national database of consumer prescription expenditures, enabling comparisons across medications, manufacturers, pharmacies, geographic regions, and time periods.

The platform provides comprehensive financial analytics and public transparency dashboards that examine federal research investment alongside pharmaceutical commercialization, available revenue information, medication pricing, and consumer spending. It identifies potential discrepancies between public contributions and private commercial benefits, tracks significant medication price increases, and highlights discoveries that may warrant additional investigation. Dedicated research and legal intelligence tools organize supporting documentation, identify potential patterns of consumer financial harm, aggregate purchase evidence, and generate detailed investigative reports for attorneys, researchers, journalists, and public interest organizations evaluating potential class actions, government recovery opportunities, and taxpayer restitution mechanisms. All findings distinguish verified information from estimates, allegations, and AI-generated investigative leads.

GrantChain is designed as an open, modular, community-driven platform that can expand through integrations with additional federal agencies, universities, pharmaceutical databases, pharmacies, insurance providers, research organizations, and legal institutions. Its features include public research repositories, interactive geographic visualizations, prescription price comparisons, secure consumer accounts, private receipt storage, collaborative investigations, public APIs, downloadable datasets, automated monitoring, and transparent evidence verification. By bringing together public research funding, pharmaceutical commercialization, medication pricing, and real-world consumer purchases, GrantChain seeks to give the public the information and evidence necessary to demand greater accountability and explore ways to return the value of taxpayer-funded medical innovation to the people who financed it.
