Blockchain technology for supply chain traceability: A game-theoretic analysis between e-platforms.

In view of the rapid development and application of blockchain technology, this paper considers a secondary supply chain system consisting of a single upstream supplier and a downstream e-tailer that implements blockchain technology and a traditional e-tailer that does not implement blockchain technology. We establish the demand function of two channels based on consumers' sensitivity to the blockchain and use the Stackelberg game model to compare and analyse the e-tailers' profits from the two channels. For the basic properties, interestingly, we find that there exists a critical threshold on the cost sensitivity to effort that helps each e-tailer decide whether to implement effort. If the cost sensitivity to effort is high, the two-sided e-tailers will reduce their effort as much as possible to obtain greater profits. Conversely, if the cost sensitivity to effort is low, they will increase their effort to obtain more benefits. We also discuss the role of blockchain technology in competition between e-tailers and analyse the impact of the product brand effect brought by the traceability characteristic of blockchain on the competition between e-tailers. To check the robustness of the core results and to investigate different forms of supply chain configurations, this paper further develops the analysis of the supplier entering agency agreements with two-sided e-tailers. Under this scenario, the supplier sells their products directly to consumers through two-sided e-platforms and shares revenue with e-tailers as platform agency fees. These core ideas remain valid in the extended model.

Counterfeit Product Detection using Blockchain Technology

A fraudulent practice where products that are passed off as genuine, product counterfeiting represents consumer fraud, which translates to financial losses. Transparency in supply chain management also faces a big challenge in terms of service repetition and lack of coordination. Numerous remedies have been implemented to battle counterfeiting, among them Artificial Intelligence and RFID, among others, all of which have significant issues such as incivility. This project tackles the problem by applying blockchain technology to improve counterfeit determination and assure product items’ authenticity all over the source chain. The scheme is built on blockchain encryption techniques, which promote a decentralized service for genuine authentication and duplication identification. Through the usage of QR codes and barcodes found in wireless technologies, counterfeit items are eradicated . When scanning a product’s QR or barcode with a camera scanner, the product’s unique code is linked to the blockchain, and all its complete details are stored within it. The database consists of multiple blocks, each one representing a unique product. In case of scanning, if the entered code matches with the database, a popup notification will display on the customer’s device that this product is genuine. Contrary to it, if there is no match found, means it is a counterfeit product; then a popup displays on the customer’s mobile, computer screen about the fraud transaction of the manufacturer from which points this scam is originating if the customer allows doing this action using the application . This will enable users to authenticate products independently without relying on sellers.

An Abnormal Account Identification Method by Topology Feature Analysis for Blockchain-Based Transaction Network

Cryptocurrency, as one of the most successful applications of blockchain technology, has played a vital role in promoting the development of the digital economy. However, its anonymity, large scale of cryptographic transactions, and decentralization have also brought new challenges in identifying abnormal accounts and preventing abnormal transaction behaviors, such as money laundering, extortion, and market manipulation. Recently, some researchers have proposed efficient and accurate abnormal transaction detection based on machine learning. However, in reality, abnormal accounts and transactions are far less common than normal accounts and transactions, so it is difficult for the previous methods to detect abnormal accounts by training with such an imbalance in abnormal/normal accounts. To address the issues, in this paper, we propose a method for identifying abnormal accounts using topology analysis of cryptographic transactions. We consider the accounts and transactions in the blockchain as graph nodes and edges. Since the abnormal accounts may have special topology features, we extract topology features from the transaction graph. By analyzing the topology features of transactions, we discover that the high-dimensional sparse topology features can be compressed by using the singular value decomposition method for feature dimension reduction. Subsequently, we use the generative adversarial network to generate samples like abnormal accounts, which will be sent to the training dataset to produce an equilibrium of abnormal/normal accounts. Finally, we utilize several machine learning techniques to detect abnormal accounts in the blockchain. Our experimental results demonstrate that our method significantly improves the accuracy and recall rate for detecting abnormal accounts in blockchain compared with the state-of-the-art methods.
