Short Answer Questions
Traditional barcode systems are susceptible to copying, counterfeiting and theft. Because each barcode is stored in a local and independent database, it is difficult to track products that have strayed from the supply chain trajectory.
Blockchain technology improves supply chain management by creating a secure and immutable record of products. This makes it possible to track the entire journey of a product from creation to delivery, thereby improving transparency and accountability.
The system described verifies the authenticity of products by scanning barcodes on them and comparing the scanned information with information stored on the blockchain. If the information matches, the product is considered authentic.
During the physical transport process, each time a product barcode is scanned, the system creates a new block on the blockchain. This block contains information about the time, location, and person responsible for the shipment, providing a real-time tracking record of the product.
In the system, a "project" represents an overall project or goal, such as supply chain management for a specific product. A "product" refers to a specific commodity created within a project, while a "batch" refers to a group of products that share common characteristics, such as the same production date or batch number.
The system provides a user-friendly interface that allows users to view product information, track shipping progress, and monitor system activity. This transparency helps build trust in the integrity of the system and enables users to take responsibility for their actions.
The system uses two types of scanning technology: one-dimensional (1D) and two-dimensional (2D) scanning. 1D scanning is used to read traditional barcodes, while 2D scanning is used to read complex codes that contain more data, such as QR codes.
The High Value Data Sharing Protocol (HVDP) allows governments to securely share passport information for verification purposes. The system utilizes HVDP to access passport data from government servers and compares it to scanned passport information to verify its authenticity.
The system can use smart cards to securely store identity information, such as biometric data or blockchain information. Smart cards contain a microchip that stores information and interacts with the system to verify the user's identity.
In addition to supply chain management, the system can be applied to various fields that require secure authentication and tracking, such as healthcare record management, educational credential verification, and government identification systems.

Glossary of Key Terms
Blockchain: A growing list of records, called blocks, that are linked together through cryptography and organized in chronological order. Each block contains a hash of the previous block, a timestamp, and transaction data, making it tamper-proof.
Distributed Ledger: A database that is shared and synchronized between multiple participants in a blockchain network. This eliminates the need for a centralized authority and improves transparency and security.
Smart Contract: A self-executing contract stored on a blockchain. These contracts execute automatically when predefined conditions are met, building trust and transparency between parties.
High Value Data Sharing Protocol (HVDP): A protocol that allows governments to securely share passports and other important identity information.
Internet of Things (IoT): A network of physical objects connected to each other via the internet that collect and exchange data. Blockchain technology can enhance the security, transparency, and traceability of IoT systems.
Crypto Hash: A one-way function that transforms an input of arbitrary length into an output of fixed length. Even small changes in the input produce a completely different hash value, ensuring the integrity of the data.
Public Key Infrastructure (PKI): A system that supports the use of digital certificates and public key cryptography to authenticate and secure communications.
Optical Character Recognition (OCR): A technology that converts printed or handwritten text in an image into machine-readable text.
Radio Frequency Identification (RFID): A technology that uses electromagnetic fields to automatically identify and track objects to which a tag is attached.
QR Code: A two-dimensional barcode that can store large amounts of information and can be easily scanned using smartphones and other devices.
