By comparing a document’s hash with the one stored on the ledger, the system confirms its authenticity and verifies its origin without requiring direct involvement from the issuer. The solution features a backend developed in Express, an IPFS system for decentralised data storage, and a React-based front-end for user interaction. It streamlines the verification process through RESTful APIs, enabling the issuance, acceptance, and rejection of transactions on the network. This systemdemonstrates how blockchain technology can enhance trust and security in document validation, offering amore efficient and tamper-resistant verification process.

By using data from vibration and temperature sensors, the digital twin will simulate and analyse the conveyor belt’s performance under different conditions and therefore predict potential failures without disrupting hardware. A 3D simulation will be created to reflect the physical systemand integrate real-time sensor data. A dashboard displaying the system status will allow parameter adjustments that reflect instantaneously on the physical model. This will demonstrate seamless interaction between the physical and virtual systems enhancing the operational efficiency of the conveyor belt.
