Roadblock Title:

Eliminating NIGO at the source: Architecting a scalable verification framework

Time:

Wednesday - 2:00 PM (Tower B)

Abstract:

Financial workflows often rely on unverified, user-submitted data; driving high NIGO rates, failed transactions, and downstream errors. Our early solution hardcoded, type-specific validation plugins and quickly hit scalability limits. In this talk, we’ll walk through our evolution from a brittle plug-in model to a Strategy Pattern that decouples verification logic from platform code. Using an annotation-based approach (@VerifiableType), we enabled developers to inject custom validation strategies into a generic verification context, eliminating bottlenecks while enforcing data truth across workflows. Learn how we built a flexible, composable framework for declarative data validation at scale.
