AbstractThis technical whitepaper proposes DLT-DSA (Distributed Ledger Technology – Decentralized Sovereign Access), a distributed data architecture designed to simultaneously ensure data integrity and scalability in decentralized environments. To alleviate the operational costs and performance limitations of existing distributed ledger structures that over-rely on consensus, DLT-DSA adopts a verification structure based on the reallocation of consensus roles, Self-Hash Verification (SHV), and Reduced Overhead Access (ROA)-based access optimization. Key architectural components: Self-Hash Verification (SHV): Autonomous tamper detection using embedded metadata. Reduced Overhead Access (ROA): Optimization layer to minimize verification bottlenecks. Hybrid Distributed Architecture (HDA): Modular foundation for service-agnostic scalability. Proof of Concept (PoC) experiments confirm that DLT-DSA achieves significant latency reduction and resource efficiency compared to traditional RDB models while maintaining robust data integrity. This architecture serves as a scalable foundation for real-time APIs, public services, and distributed data operations.
