Interside: Blockchain Interoperability Architecture for Supply Chain Tracking

This paper presents “Interside,” a novel architectural framework leveraging private blockchain technology for secure, scalable, and interoperable end-to-end supply chain tracking. Recognizing the prevalent issues of fragmentation, isolated blockchain im-plementations, and inconsistent governance within modern supply chains, Interside proposes a side-by-side interoperability model supported by layered governance, de-centralized identity management, and cryptographic verification. The architecture is functionally benchmarked against alternative approaches such as direct interoperability solutions and hub-based intermediary frameworks. Findings indicate that Interside offers a decentralized system with trustless cross-chain integration and enhanced security features. Preliminary performance assessments suggest that the proposed architec-ture attains levels comparable to direct interoperability models. This project contributes a standardized blueprint for multi-network supply chain interoperability.
