Optimizing traceability scheme in a fresh product supply chain considering product competition in blockchain era

Fresh product traceability plays an integral role in ensuring food safety. Recently, many firms have introduced blockchain technology (BCT) for product traceability to guarantee product authenticity and consumer rights. However, introduction of the new technology has also intensified the competition among fresh products. Meanwhile, previous studies on traceability strategies only considered the impact of traceability cost and ignored the issue of increased product competition in blockchain era. Driven by these problems, we build a game-theoretical model to analyze the optimization of traceability schemes for both low-end fresh products (LEFP) and high-end fresh products (HEFP) in a fresh product supply chain (FPSC) in a competitive environment. Moreover, this paper investigates the impact of power structure on traceability schemes and identifies the conditions under which one scheme outperforms the others. We find that the cost per unit of product input has no effect on the traceability decision of the FPSC. Nonetheless, the introduction of BCT increases the number of consumers who choose LEFP and raises the selling price and wholesale price of corresponding products. Finally, from the supply chain perspective, it is best to adopt the same traceability scheme for both products. This study sheds light on the use of BCT in traceability can provide enhanced product authenticity and consumer rights while increasing product competition and demonstrates the significance of traceability schemes in the FPSC.

Unpacking the relevance of interpersonal trust in the blockchain era: Theory and experimental evidence

Despite being proclaimed a “trust-free” technology, the link between blockchain and interpersonal trust remains understudied. By considering one of the most prominent use-cases of blockchain - smart contracts, we argue that the non-punitive nature of smart contracts may facilitate trustworthy behavior in human interaction by encouraging trustees to view themselves as internally motivated cooperators and to honor the trustor’s move that exceeds the encoded response. We test this argument through an online experiment in which the hallmark property of smart contracts—automated enforcement—is exploited. The results show that trustees in the experimental treatment return ten percentage points more than their counterparts in the trust treatment, thereby exhibiting a more trustworthy behavior. This experimental evidence shows that the presence of blockchain technology does not crowd out all properties of trusting behavior from human interactions.

Dynamic Incentive Contract of Government for Port Enterprises to Reduce Emissions in the Blockchain Era: Considering Carbon Trading Policy

Blockchain technology is very useful. This paper considers the application of blockchain technology to smart contracts, green certification, and market information disclosure, and introduces the carbon trading market price as a parameter to solve the dynamic incentive problem of the government for port enterprises to reduce emissions under the carbon trading policy. Based on the state change of port carbon emission reduction, this paper uses principal–agent theory to construct the dynamic incentive contract model of government without blockchain, with blockchain, and when carbon trading is considered under blockchain, respectively, and uses the optimal control method to solve and analyze the model. This paper finds that only when the opportunity cost of port enterprises is greater than a certain critical point and the fixed cost of blockchain is less than a certain critical point, the implementation of blockchain will help improve government efficiency. However, only when the critical value of carbon emission reduction of port enterprises and the unit operating cost of blockchain are small, the government should start the carbon trading market under blockchain technology. Through numerical simulation, this paper also finds that it is usually beneficial for the government to regulate and appropriately increase the carbon trading market price.

Competition between green and non-green products in the blockchain era

Blockchain technology has been used to certify the green level of green products, which changes the competition landscape between green and non-green products. We explore the important issue concerning how blockchain adoption affects the duopoly game between green and non-green products. We first examine a benchmark case where blockchain is not used. Then we develop two pricing models to analyze the value of blockchain adoption and the competition landscape between green and non-green products, where one concerns a green product manufacturer that applies blockchain to certify the green level of its product, and the other concerns a non-green product manufacturer. To assess the robustness of the results, we extend the models to consider two important cases, namely (i) substitutability between green and non-green products, and (ii) mixed competition including the simultaneous presence of conventional, blockchain-enabled, and non-green products in the marketplace. We show that the green product manufacturer does not necessarily increase its price when adopting blockchain, whereas the non-green product manufacturer does. Specifically, when the green level is high, the GPM's blockchain adoption decreases price competition between green and non-green products, causing both the green and non-green product manufacturers to raise prices. In addition, it is intriguing to find that the presence of more sustainable consumers in the market does not cause the green product manufacturer to charge a higher price than the non-green product manufacturer. Under the mixed competition scenario, as a result of blockchain adoption, the blockchain-enabled green product manufacturer charges a higher price than the green and non-green product manufacturer. However, this does not inherently result in a higher profit margin for the blockchain-enabled green product manufacturer.

Fake Product Detection Using Blockchain Technology

Abstract: There are several fake products in the existing supply chain markets. It is necessary to have a system for end users to check all details about the product they are buying so that the customer can check if the product is genuine. In recent years, faking products play an important role in product manufacturing industries. Faking products affects the company name, sales, and profit of the organizations. Blockchain technology is used for the identification of actual merchandise and the detecting of faux products. Blockchain technology is generally a tally system that stores all the data of the deals that take place in it. The precise aspect approximately this era is that the tally we referred to is a allotted tally in a peer-to- peer community. Blockchain generation is relaxed as the facts saved once within the chain is immutable consequently any block cannot be modified or hacked. with the aid of using Blockchain era, clients or customers do no longer want to rely on users for confirmation of product authenticity and protection. Our device affords the rising generation of web use instances, and brief reaction (QR) codes offer a unique but affectable method to triumph over these faking of products. Counterfeited merchandise may be detected the use of a QR code scanner, wherein the QR code of the product is linked to the Blockchain. So, this system can be used to store product info and generate particular code of that product as blocks inside the database. It collects the precise code from the consumer and compares the code against entities within the Blockchain database. If the code matches, it will give all the information about the product otherwise no data can be outputted to the purchaser which shows that the product is fake or counterfeited.

The Choice Strategy of Authentication Technology for Luxury E-Commerce Platforms in the Blockchain Era

Blockchain technology, as an emerging information technology, has attracted much attention. Some luxury e-commerce platforms have focused on the adoption of blockchain technology to provide electronic certificates for consumers, which helps to increase consumers’ trust in luxury goods. However, due to the high authentication cost of blockchain technology, some platforms still adopt manual technology with lower authentication costs to provide paper certificates for consumers. So whether platforms choose to adopt manual technology or blockchain technology for authentication is a problem worthy of attention. In this article, we investigate the choice strategy of authentication technology for luxury e-commerce platform(s) in the monopoly and duopoly markets, respectively. The results show that the choice of authentication technology for platform(s) depends on the cost difference between manual technology authentication and blockchain technology authentication. When the cost difference is small (large), platform(s) should adopt blockchain (manual) technology. In particular, in the duopoly market, the competition between the two platforms will improve their motivation to adopt blockchain technology, but the two platforms may trap into a prisoner's dilemma when they both adopt blockchain technology. Moreover, in the monopoly and duopoly markets, adopting blockchain technology is likely to improve consumer surplus and social welfare at the same time.

YouTube Clone by Using Ethereum Block Chain

Decentralized video sharing structures are much like video sharing structures wherein creators post content material and customers view it. However, the primary distinction lies withinside the community in the back of the decentralized video sharing platform. A peer-to-peer (P2P) community of decentralized video sharing structures helps the steady switch of files. To make sure speedy facts switch, facts is break up into smaller blocks for less complicated switch and download, making sure quicker downloads and browsing. The decentralized video sharing platform transfers facts over a P2P community, however with an extra layer of blockchain era encryption. Less operational value, higher fault tolerance, much less consider necessities among garage carriers and facts owners, and much less vulnerability to attacks. An occasion in blockchain era has delivered a decentralized garage mode to the public. Video transcoding is extensively carried out in video streaming commerce, changing films into a couple of codecs for extraordinary audiences.

Antitrust Live

The reports of antitrust’s death at the hands of decentralized blockchains were an exaggeration. The premise is logical: decentralized markets should mitigate the need for antitrust laws, which typically address abuses of power by, and secret collusion among, centralized firms in concentrated markets. Indeed, blockchains strive to prevent market structures that facilitate collusion and monopolization in the first place through decentralization, a form of antitrust self-regulation. And blockchain communities are debating and deciding how to effect this self-regulation, with the potential for autonomous implementations of market constraints designed to preserve decentralization, in real time and in public. All of this means that antitrust principles are very much alive on the blockchain. However, there exists a conflict: recent efforts to self-regulate antitrust may constitute per se violations of the very laws that such efforts are intended to preempt. The first to identify this conflict, this Article proposes that antitrust is entering a new blockchain era, one that is self-regulated and transparent, but not without risks. This Article then argues that self-regulation efforts in the blockchain context that would normally receive per se condemnation by U.S. courts, like price fixing, should instead receive more fulsome reviews under the rule of reason. The procompetitive potential of such self-regulation, combined with judicial inexperience in complex blockchain markets, warrants such an approach.

Innovating Healthcare IoT with a Secure Blockchain Consensus Algorithm based on Verifiable Random Ranking

The Internet of Things (IoT) is helping the healthcare industry innovate. Medical professionals are no longer confined to hospitals or physical locations. IoT devices are used in healthcare for remote monitoring of vital signs, transmission and reception of private data, and other similar applications. Protection from cyber threats is the most vital aspect of IoT device operation. Malicious activities result in the leakage of sensitive data and the malfunctioning of devices, which becomes a critical issue. As a result, it is now a serious endeavor to create effective solutions that can safeguard the data and record exchange networks of every IoT device. To address some critical issues with current consensus algorithms, this paper proposes the verifiable random ranking (VRR) based Secure Blockchain Consensus (SBC) mechanism. In place of conventional algorithms, we developed new techniques for managing active nodes and evaluating node reliability and robustness. Our experiments show that the VRR-SBC algorithm speeds up consensus, improves security, and reduces the price of verification. The results of the simulation demonstrate the usefulness of the blockchain era for limited devices and provide an opportunity to assess the scope of the consensus algorithm's applicability.

Triple Entry Bookkeeping di Era Teknologi Blockchain: Suatu Kajian Literatur

The financial industry in the era of technological development began to be supported by Blockchain technology. Blockchain is a new idea in the financial industry as a solution to solve the problem of digital money (cryptocurrency). Transactions recorded in the blockchain will be permanently stored so that they cannot be manipulated and provide a higher level of security. Blockchain technology supports the development of triple entry bookkeeping which is a configuration of the development of the double entry bookkeeping system. This research uses qualitative proximity to the library research method. The data collected comes from indexed journals on Google Scholar, Science and Technology (Sinta), Directory of Open Access Journals (DOAJ), books and other literature which will then be analyzed and set forth in the form of written words.The results of this study show that Triple Entry Bookkeeping in the Blockchain era has many advantages as a form of development of Double Entry Bookkeeping, namely providing information about budgets, automatic transaction validation, automatic public ledger, increasing openness & trust, and solving fraud. In Indonesia itself, blockchain implementation in the field of accounting has been widely carried out, such as on the Online Pajak platform, Bank BCA, PT Pos Indonesia, and other commercial companies listed on the Indonesian Blockchain Association (ABI). The implementation of the triple entry bookkeeping system is still not ready to be implemented by medium-sized entities and MSMEs due to the high costs required, the lack of understanding of professional accountants regarding technology and entities that feel they still do not need a triple entry bookkeeping system. Therefore, support from all parties is needed so that this research can develop and not only become a concept but can be implemented in the financial industry.

Evolution of Industry and Blockchain Era: Monitoring Price Hike and Corruption Using BIoT for Smart Government and Industry 4.0

The price gouging or price hike is a worldwide issue, and it is related to inflation. Because of rising prices, people in various countries cannot afford nutritious food or proper treatment. Sometimes shops, restaurants, and transportation service providers charge more than the prescribed product price from buyers. In addition, unauthorized VAT or Tax is taken on products that the government exempts. Another reason for price hikes is bribery, and it occurs in transporting and delivering goods. This article introduces a blockchain-based Internet of Things model to monitor product price hikes and corruption from the Industry 4.0 and blockchain 5.0 point of view. Industries produce and package different products. Wholesalers and retailers purchase products from industrial companies.
