DEFIANCE: Decentralized Evidentiary Forensics for Immutable Auditability, Networked Chain-of-Custody, and Enforcement (A Blockchain-Based Forensic Firearm Tracking System and Evidentiary Dataset)

This dataset supports the thesis "A Cryptographic Architecture for Decentralized Firearm Forensics" and contains the complete codebase, verification artifacts, deployment scripts, audit records, forensic output samples, and evidentiary templates that comprise the DEFIANCE system — the first decentralized blockchain-based firearm forensic infrastructure.

DEFIANCE enables smart contract–governed NFT firearm identity, biometric transfer validation, multisignature warrant-based access control, and zero-knowledge-compatible forensic event logging. This dataset includes all modules necessary to deploy, test, audit, and reproduce the system in compliance with U.S. evidentiary law (Federal Rules of Evidence 902(13) and 902(14)) and academic reproducibility guidelines.
