Trustworthy Data-Driven Infrastructure for Digital Philanthropy: A Verification-Centric Platform with Geospatial Discovery and Structured Need–Surplus Matching

Nabhya was presented in this paper, and the structural features it has – organizational trust, item level bidirectional giving, and volunteer verification – are built into the platform from the very beginning. Three architectural properties can be demonstrated using the evaluation results. First, unverified or suspended entities are prevented from appearing in the evaluated public discovery mech-anisms by predicates on the query level. Second, the 27-table schema uses database constraints and transaction locks to en-force the properties of uniqueness, capacity, and fulfillment. Third, integration and concurrency testing verifies these prop-erties on a PostgreSQL database produced by migration, while quantitative evaluation provides performance baselines. Deployment in the field with actual donors, volunteers, and NGOs, along with longitudinal evaluation of adoption and per-ceived trustworthiness, is a task for the future. Improving verifi-cation by performing regular cross-validation and re-verification against external registries is also required in production use (Sec-tion 6.4). With all these limitations, Nabhya demonstrates a testable blueprint of trustworthy infrastructure for data-driven smart social applications.
