TRUST-Court: Tamper-Resistant Records for Universal Secure Transparency in Digital Judiciary Systems

What if a court verdict could never be altered—not today, not tomorrow, and not even in the age of quantum computers? This paper introduces textbf{TRUST-Court}, a next-generation digital judiciary framework that makes court records textbf{tamper-proof, transparent, and quantum-secure}. Every participant in a case—plaintiff, defendant, lawyer, and judge—receives a verified digital identity and signs court proceedings using textbf{post-quantum cryptographic algorithms standardized by NIST in 2024}. Hearings are transcribed in real time, digitally signed by all parties, and permanently sealed using multi-layer cryptographic protection before being anchored to a blockchain for public verification.The system integrates permissioned blockchain infrastructure (Hyperledger Fabric), public verification anchoring (Polygon), and post-quantum cryptographic primitives including textbf{ML-DSA, ML-KEM, SLH-DSA, SHA-3, and AES-256}. To address the large data sizes of post-quantum signatures, we introduce practical storage optimization techniques such as Merkle-tree batching, signature aggregation, and archival compression, achieving textbf{60–80% storage reduction} while preserving security guarantees. Through case studies from the United States, India, and Ireland, TRUST-Court demonstrates how judicial records can become mathematically verifiable public artifacts. By preventing document tampering, eliminating transcript disputes, and enabling citizen-level verification of verdicts, the framework offers a pathway toward a judiciary where textbf{truth, once recorded, becomes permanently unalterable}.
