Tracker Combined with Blockchain Technology

The integration of blockchain and tracker technology offers new possibilities for data transparency, security, and traceability. Blockchain provides a decentralized, immutable system of record, while tracker technology offers real-time data updates. This combination delivers significant application value across multiple fields, though it also requires careful consideration of the complexity of implementation and the balance between privacy and security.

Pharmaceutical Field - Euler Pharmaceutical eZTracker

Background: The pharmaceutical market is plagued by issues such as counterfeit drugs and parallel imports, making it difficult for patients to verify the source of their medications. The transparency and security of the pharmaceutical supply chain are in urgent need of improvement.

Combination Method: Euler Pharma's eZTracker utilizes blockchain technology to assign a unique encrypted ID to each pharmaceutical product, thereby serializing them.

Application Effect: This system enables biotech pharmaceutical companies to access real-time data on product information and inventory management. Consumers can scan QR codes to verify whether a drug has been legally approved. It has been instrumental in confirming the approval status of vaccines and medical aesthetic products in Hong Kong and Thailand. Additionally, it supports the management of cold chain products and the creation of electronic records.

Logistics - IBM and Maersk Tradelens Platforms

Background: In global maritime logistics, common issues such as opaque information, cumbersome document processing, and the risk of fraud negatively impact logistics efficiency and cargo safety.

Combination Method: The Tradelens platform, built on blockchain technology, integrates information from multiple stakeholders, including customs, transportation companies, and port management agencies.

Application Effect: It enables real-time tracking and management of the location, status, and ownership of maritime cargo worldwide. By automating the processing of transportation documents and payments through smart contracts, it enhances operational efficiency and reduces the risk of fraud in the logistics process.

Food - Walmart and IBM's FoodTrust Platform

Background: Food safety issues are a frequent concern, with consumers highly attentive to the origin and safety of their food. Traditional food supply chain traceability is often inadequate.

Combination Method: FoodTrust utilizes blockchain technology to build a food traceability system that records information on every aspect of food, from planting and processing to transportation.

Application Effect: Consumers can scan QR codes to view the entire process of food information, thereby increasing their trust in food safety. In the event of a food safety issue, the platform can quickly identify the affected batch, reducing the scope and cost of product recalls.

Second-hand Market - Digital Chain Blockchain-based Commodity Logistics Tracking Method

Background: The lack of safe, transparent, and efficient logistics information management in the second-hand market affects the trust and development of second-hand transactions.

Combination Method: A distributed ledger is established on the blockchain to record the logistics information of second-hand goods. The information is encrypted and processed, verified and stored using a consensus mechanism, and a unique logistics tracking identifier is generated. Smart contracts are used to automatically update and verify the information.

Application Effect: This provides a secure, transparent, and efficient logistics information management solution for the second-hand market, effectively promoting trust in second-hand transactions and fostering healthy market development.

Blockchain Transaction Tracking - Blockchain Tracker Example

Background: In the development and application of blockchain, real-time tracking and monitoring of transactions between specific wallets are essential to ensure transaction security, validate smart contracts, and more.

Combination Method: This is a lightweight Node.js-based application that communicates with the Ethereum blockchain using the Web3.js library and connects to the Ethereum network via Infura services.

Application Effect: It can track the transfer of Ethereum and ERC20 tokens between designated wallets in real time, monitor transactions of a specific amount, and is useful for smart contract auditing, wallet security monitoring, DApp development, and blockchain data analytics.
