Chapter 1: Introduction

1.1 What Is Blockchain:

Blockchain is a distributed digital ledger that allows the secure storage and management of data without the need for intermediaries. It is a decentralized system where every participant in the network has access to a copy of the ledger and can verify the authenticity and integrity of the data stored in it. One of the most well-known examples of blockchain technology is the Bitcoin blockchain. Bitcoin is a digital currency that uses blockchain technology to record and verify transactions between users. The Bitcoin blockchain consists of a chain of blocks, with each block containing a list of transactions that have been verified by network participants. The transactions are verified through a process known as mining, where network participants compete to solve complex mathematical problems and the first one to solve the problem gets to add the next block to the chain. Another example of blockchain technology is Ethereum, a decentralized platform that allows the creation and deployment of smart contracts, which are self-executing contracts with the terms of the agreement directly written into lines of code. Ethereum uses a blockchain to store and manage the execution of smart contracts, ensuring their immutability and transparency. It can be said that blockchain is a disruptive technology that has the potential to revolutionize various industries by offering a secure, decentralized, and transparent system for storing and managing data. Its ability to provide a tamper-proof and immutable ledger has made it a popular choice for applications that require transparency, such as financial transactions, supply chain management, and voting systems. As the technology continues to evolve, it is likely that we will see more innovative uses of blockchain in the future.

1.2 What Is Supply Chain:

Supply chain refers to the network of organizations, individuals, and activities involved in the creation and delivery of a product or service from its initial conception to its final consumption. It encompasses all the stages of the product lifecycle, including design, production, distribution, and consumption, and involves the coordination of numerous stakeholders and processes. One example of a supply chain is the production and distribution of a smartphone. The supply chain for a smartphone involves numerous stages, including the design and development of the device, the sourcing of raw materials and components, the manufacturing of the phone, and its distribution to retailers and ultimately to the end consumer. Each of these stages involves a range of activities, such as research and development, procurement, manufacturing, logistics, and marketing, and requires the involvement of various stakeholders, including suppliers, manufacturers, distributors, and retailers. Supply chain can be defined as a complex and dynamic network of activities, processes, and stakeholders that are involved in the creation and delivery of goods and services. The supply chain can be viewed as a system that connects all the different stages of the product lifecycle, from raw materials to final consumption, and involves the coordination of numerous stakeholders and processes. Supply chain management plays a critical role in ensuring the efficient and effective operation of the supply chain by optimizing processes, managing risks, and building collaborative relationships with suppliers and customers. With the increasing globalization of markets and the growing complexity of supply chains, it is becoming increasingly important for organizations to develop robust supply chain strategies that can adapt to changing market conditions and customer demands.

1.3 Coordination of Blockchain with Supply Chain: 

Blockchain technology has the potential to revolutionize the way supply chains operate by providing a secure, decentralized, and transparent system for storing and managing data. By using a blockchain, supply chain participants can track and verify the authenticity and integrity of transactions at every stage of the supply chain, from sourcing of raw materials to the delivery of finished products to consumers. This can help to reduce the risk of fraud, improve traceability, and increase efficiency and transparency in supply chain management. With the increasing complexity and globalization of supply chains, the use of blockchain technology is becoming more prevalent as a means of ensuring the efficiency, security, and transparency of supply chain operations.

1.4 Why my study is different from other existing implimentation: 

 

Implementing blockchain technology in supply chain management have the potential to improve transparency, accountability, and traceability of products from the point of origin to the end-user. This is because the decentralized nature of blockchain allows a secure and immutable record of all transactions and activities in the supply chain. While there are many existing blockchain implementations in supply chain management, the uniqueness of our study lies in several factors such as:

1. Focus on a specific sector: Our study focuses on a particular sector of security, which is product authenticity and how blockchain can be implemented to address the specific challenges and requirements of authenticity.
2. Novel blockchain technology:Our study explores the use of newer and more advanced blockchain technologies, such as DAG (Directed Acyclic Graph) or hybrid blockchains, that offer more security for supply chain management.
3. Will grow the consumer faith: Our study will show how blockchain can make sure the consumer that the product is right and authentic, which will enhance the security and authenticity of supply chain data.
4. Empirical research: Our study may involve conducting empirical research to assess the. effectiveness and impact of blockchain implementation in supply chain management, providing insights and recommendations for businesses and policymakers.
5. Encourage the next generation: Our study will guide the next inventor how blockchain can be used in the authenticity checking task of product in the future.

1.5 Contribution Of the Research:

The implementation of blockchain technology into supply chain management for product authenticity verification has significant potential to contribute to the field of supply chain management and benefit the wider world. By using a blockchain, it is possible to create a tamper-proof, decentralized, and transparent system for tracking the movement of products throughout the supply chain. This can help to reduce the risk of fraud, improve traceability, and increase efficiency and transparency in supply chain management.

In the future, this implementation could pave the way for other researchers to explore the use of blockchain technology for various applications in supply chain management. For example, blockchain could be used to manage and track inventory, optimize logistics, and enhance collaboration between supply chain participants. Furthermore, the use of blockchain technology could have far-reaching implications beyond supply chain management, including the potential to disrupt other industries, such as finance, healthcare, and energy.

The implementation of blockchain technology into supply chain management for product authenticity verification could also have significant benefits for society. By providing consumers with a transparent and trustworthy system for verifying the authenticity of products, it could help to combat the growing problem of counterfeit products. This, in turn, could improve consumer safety and trust in the products they purchase.

Overall, the implementation of blockchain technology into supply chain management for product authenticity verification has the potential to revolutionize the way supply chains operate, enhance transparency, and provide significant benefits to society. As such, it represents an exciting area of research that is likely to continue to grow in importance in the future.

Chapter 2: Motivation

2.1 Problem Statement

 We are doing blockchain implementation in supply chain management. The main problem in the supply chain is+ frauding. Fraud in supply chain management means when someone does something illegal or dishonest in the supply chain to benefit themselves at the expense of others. Fraud can happen at any point in the supply chain, and there are different types of fraud, like stealing, making fake products, or lying about the quality of products [1]. For example, a supplier may say their products are high quality to get paid more, or an employee may steal things from the warehouse to sell them illegally. Fraud can cause financial loss, harm reputations, and lead to legal consequences. We are trying to prevent fraud in supply chain management by implementing blockchain in it. The thesis is focused on finding ways to prevent fraud in supply chain management. To do this, the thesis will explore the use of blockchain technology in supply chain management. Blockchain can provide increased transparency and traceability in the supply chain, which can help prevent fraud. The thesis also aims to identify any gaps or issues in the current use of blockchain in supply chain management, so that developers can conduct further research to address these issues. This will help to make blockchain more effective and efficient in preventing fraud in the supply chain. The thesis will explore how blockchain can prevent fraud in supply chain management and provide recommendations for developers to improve the use of blockchain in this area.

2.2 Usage of Blockchain in modern indutry

Blockchain technology has gained significant attention in various industries due to its potential to provide a secure, decentralized, and transparent system for managing transactions and data. In recent years, several studies have explored the use of blockchain in modern industries, ranging from finance to healthcare, supply chain management, and beyond. In this literature review, we will summarize some of the key findings from recent research on the use of blockchain in modern industries[2]. According to a study by Ali et al. (2020), blockchain technology has the potential to transform the financial industry by enabling real-time settlement, reducing fraud, and increasing transparency. The study suggests that blockchain can reduce costs by eliminating intermediaries and reducing the need for manual reconciliation. In a study by Xu et al. (2021), blockchain technology was found to improve supply chain transparency and reduce the risk of counterfeiting[3]. The study proposes a blockchain-based supply chain management system that can enhance trust and collaboration among supply chain stakeholders. A study by Yang et al. (2021) explores the potential of blockchain technology to improve the security and interoperability of electronic health records (EHRs). The study proposes a blockchain-based system that can facilitate secure sharing of EHRs while protecting patient privacy[4]. According to a study by Wang et al. (2020), blockchain technology can enable peer-to-peer energy trading and increase the penetration of renewable energy sources. The study proposes a blockchain-based energy trading platform that can reduce energy costs and promote the use of clean energy sources. In conclusion, the use of blockchain technology in modern industries has the potential to revolutionize the way we manage transactions and data. While the technology is still in its early stages of development, several industries have already begun exploring its potential. As the technology continues to evolve, it will be interesting to see how it will transform various industries and enable new business models[5].

2.3 Is block chain necessary for supply chain

Blockchain is not strictly necessary for supply chain management, but it can provide certain benefits such as increased transparency, security, and efficiency. The decision to use blockchain in a supply chain will depend on the specific needs and requirements of the organization involved.

Blockchain technology has been increasingly used in various industries, including supply chain management. However, the question remains whether blockchain is necessary for supply chain management or not. In this article, we will explore the potential benefits of using blockchain in supply chain management, and whether it is a necessary technology for modern supply chains.

To begin with, the supply chain is a complex network of entities that includes manufacturers, suppliers, distributors, and retailers, among others. The supply chain management process involves coordinating and managing the flow of goods, services, and information from the source to the end-user. The traditional supply chain management systems are often fragmented, with various intermediaries involved in the process, leading to inefficiencies, delays, and higher costs.

Blockchain technology offers potential solutions to many of the challenges facing the supply chain. Blockchain is a distributed, immutable, and transparent ledger that can record all transactions in the supply chain in real-time. It offers a secure and decentralized platform where all stakeholders can share data and collaborate in real-time, eliminating the need for intermediaries and improving trust and transparency.

One of the most significant benefits of blockchain in supply chain management is increased transparency. Since all transactions are recorded on the blockchain, all stakeholders can access and verify the information in real-time, improving visibility and traceability. This can help reduce fraud and counterfeiting, as well as prevent the shipment of counterfeit products. Moreover, blockchain technology can enable faster identification of the source of the problem in case of a recall, making the process more efficient.

Another benefit of blockchain in supply chain management is enhanced security. Blockchain is based on cryptography, and the data stored on the blockchain is tamper-proof, ensuring the authenticity of the information. This means that supply chain stakeholders can securely share sensitive information without the risk of data breaches or unauthorized access. Additionally, blockchain can prevent unauthorized changes to the information stored on the blockchain, ensuring data integrity.

Blockchain can also improve the efficiency of the supply chain management process. By eliminating intermediaries, blockchain can reduce transaction costs and increase the speed of transactions. The decentralized nature of blockchain can also enable real-time tracking and monitoring of goods and services, reducing delays, and improving delivery times. This can help improve the customer experience and increase customer loyalty.

Howver, it is important to note that blockchain is not necessary for supply chain management. Traditional supply chain management systems can still function effectively, albeit with some limitations. For example, traditional supply chain management systems are often slow, manual, and prone to errors, leading to delays and inefficiencies. Moreover, traditional supply chain management systems may not provide the level of transparency and security required in modern supply chains.

Therefore, the decision to use blockchain in supply chain management will depend on the specific needs and requirements of the organization involved. Organizations with complex supply chains and a high volume of transactions may benefit the most from using blockchain technology. However, smaller organizations may not necessarily require blockchain to manage their supply chains effectively.

In conclusion, blockchain technology has the potential to revolutionize supply chain management by providing increased transparency, security, and efficiency. However, it is not a necessary technology for modern supply chains, and the decision to use blockchain will depend on the specific needs and requirements of the organization. The use of blockchain in supply chain management will likely continue to grow as more organizations recognize the potential benefits of this technology.

2.4 Security and safety issues of the Supply Chain

The supply chain is the process by which products or services are made and delivered to consumers. It involves many different companies, individuals, and organizations working together to produce, transport, and distribute goods. However, this complex system also creates security vulnerabilities that can be exploited by attackers. These security issues can include theft, counterfeiting, sabotage, and cyber attacks, among others. When one part of the supply chain is compromised, it can have a ripple effect on the entire system, leading to disruptions and potentially compromising the safety and security of the end users. Therefore, it’s important to implement robust security measures throughout the supply chain to ensure the integrity of the products and services being delivered.

There are issues regarding safety in the supply chain. Problems with safety and security in the food, medicines, medical devices, consumer goods, and automotive industries, among others. [6]

There is process disruption, Supply chain disruptions are events or circumstances that disrupt the flow of goods, services, or information in a supply chain, leading to delays, inefficiencies, or interruptions. Examples of supply chain disruptions include natural disasters, transportation disruptions, supplier disruptions, demand fluctuations, geopolitical and trade disruptions, technological disruptions, and pandemics or health crises. These disruptions can have significant impacts on businesses, such as increased costs, lost sales, damaged customer relationships, and reputational risks. [7]

Terrorism and political instability can create significant challenges for global supply chains. They can disrupt the movement of goods, services, and information, resulting in delays, disruptions, and increased costs. Some specific challenges include disruptions in transportation, such as attacks on infrastructure or hijacking of shipments, disruptions in supplier operations due to political instability, border closures, and trade disputes, increased security measures and costs to mitigate terrorism threats, and reputational risks for businesses due to instability in regions where suppliers or partners are located. These challenges can impact the efficiency, cost, and reputation of the supply chain, requiring proactive measures to mitigate risks and maintain smooth operations. [7]

2.5 What are the aspects uses of blockchai

We are doing blockchain implementation on supply chain management where blockchain can provide a secure and transparent record of a product’s journey through the supply chain, improving efficiency and reducing the risk of fraud. Except this blockchain technology has various use cases across various industries, some of the most common ones include:

• Cryptocurrency: Cryptocurrency refers to a digital or virtual currency that utilizes

cryptography for security and operates independently of a central bank. It is based on the

decentralized blockchain system and runs independently of a central bank. It records

transactions made with a certain cryptocurrency. A block cannot be changed or removed

after it has been added to the chain.[8]

• Digital identity: Blockchain is a safe way to keep personal information. It helps people

control and share their digital identity, which is like their online version of themselves.

This includes things like their name, date of birth, address, and what they do online.[9]

• Smart Contracts: Self-executing contracts with the terms of the agreement betweenbuyer and seller being directly written into lines of code and automatically enforce the terms of an agreement when certain conditions are met. They offer a secure and transparent way of conducting transactions and have the potential to transform traditional contractual relationships.[10]
• Voting: A blockchain-based voting system gives each voter a special digital identity. Their votes are recorded on the blockchain and checked by many different parts of the system. This makes sure that every vote is counted correctly and can’t be changed. When the voting is finished, the results are shown for everyone to see. This helps make the voting process fair and stops cheating.[11]
• Health care: Blockchain can keep medical records safe and help doctors see and share them more easily. This technology can make healthcare better by making it easier to share information, making it more secure, and making sure different computer systems can work together. By keeping health information private and safe, blockchain can make healthcare better for everyone. [12]

 

2.6 What are the other methods, used in supply chain management?

1.  Continuous Flow

This is one of the most traditional models on the list. The continuous flow model is the best choice for industries and businesses that operate with stability. Stability is essential for this model because it is required on both ends, i.e., at the manufacturer and the buyer. This model is well-suited for businesses that produce a uniform set of goods and can expect a stable level of demand from the market. As the name suggests, goods are in continuous flow in this model, and it is based on the stability of supply and demand in the market. The systems in this type of supply chain management method are aligned so that a continuous flow of goods can be ensured.

2. Fast chain

The fast chain model is one of the new names in supply chain strategies. It is suitable for businesses that have product lines with short life cycles. For instance, a fashion designer might have a specific line of designs in a season. The business needs to take the fashion line to the market to maximize returns, as it is usually based on current trends. As supply chain efficiency can increase a business’s competitive edge, this model is usually considered the best among the several types of supply chain integration.

3. Efficient Chain

The efficient chain model has been crafted for hyper-competitive industries. Under this model, the end goal is to maximize efficiency. Following the efficient chain model, the organization is expected to create proper production forecasts so that it can prepare machinery and raw materials accordingly. The biggest drawback of this model is that a disruption in the production or sales cycle can create a lot of ripple effects across the supply chain network. For instance, challenges like labor shortages or raw material shortages could cause lengthy delays, and the organization may have to bear additional costs due to the delay in supply.

4. Agile

The agile model is well-suited for businesses dealing with specialty items where products may require extra care in the supply chain. This model is usually fine-tuned for the product that it is being used for. The agile model is known for the expertise it requires to transport the goods from point A to point B and not so much for the automation or technology involved. Supply chain companies that follow the agile model can charge a premium price for their services. Compared to the efficient chain model that thrives on high volumes, the agile model is only profitable till a threshold of volume is met. After that, it may prove costly to follow this model.

5. Custom-configured

The custom-configured model needs custom setups in the assembly and production stages. It is a mix of agile and continuous flow methods where the product that is being manufactured may require some extra customization, but it needs to operate on an end-to-end basis. It is usually used for prototype design and manufacturing of small batches. The custom-configured model requires additional investment from the company as compared to more traditional models.

6. Flexible

The flexible model can handle high demand during peak season and quickly adjust to a lean period with low demand. To run a flexible model efficiently, a business requires the right supply chain management software and the right people with the knowledge base to operate a flexible model with high efficiency.

21. The logistics and supply chain management community realizes how Blockchain could have an impact on your industry. To shed light on this emerging field, we have conducted an online survey and sought advice from logistics professionals Examples of blockchain use cases, barriers, intermediaries and general perspectives in logistics and supply chain management. However, factors such as hierarchy level, Blockchain experiences and industry sector have an important impact on the evaluation of the participants. It took longer for logistics and supply chain management (SCM) . The community recognized this and slowly realized the impact blockchain could have on their industry. Supply chain transparency is one of the most important and most difficult improvement points for logistics e SCM (Abeyratne & Monfared 2016). This can be explained by the novelty of technology, but also so clearly due to the lack of compelling use cases showing the advantage of blockchain over existing IT solutions. SCM Logistics and Research on blockchain is still in its infancy. We then present the results of an international survey that we conducted within the logistics industry to examine the perspectives of the four use cases and Blockchain expectations and concerns. In this paper, we presented a study on the current state of Blockchain in logistics and SCM. To shed light on the first research question pertaining to possible applications of Blockchain in logistics and SCM, we introduced four use case examples that are under exploration in theory and practice. To provide insights into the second research question about Blockchain being a trick or a treat for logistics and SCM, we presented the findings of a survey. The survey was conducted in the logistics and SCM industry and investigated the participants’ opinion on use cases, showstoppers, and benefits of Blockchain. As our findings show, Blockchain is expected to have a considerable impact on the logistics industry and should be considered a treat. However, our findings also show logisticians should start “chewing” on Blockchain soon. They are well-advised to find out how much of the overall Blockchain hype could be developed into a value-add for their service portfolio before someone else does.[27]

 

22. This paper aims to combine the perspectives of business practice and academic research on the use of blockchain technology (BCT) in supply chain management (SCM). A comprehensive framework of use case clusters is developed and used to analyze 53 applications of BCT in SCM, which are derived from a systematic literature review and a secondary dataset of blockchaindriven innovations in SCM.

Chapter 5: Methodology

5.1 Problem Domain And Scenario:

The methodology employed in this thesis titled “Blockchain Implementation on Supply Chain to Check Product Authenticity” is predominantly qualitative in nature. The primary focus of this research is to explore and understand a new aspect of implementing blockchain technology within the supply chain industry to verify the authenticity of products.

Qualitative research methods will be utilized to gather in-depth insights, opinions, and perspectives from relevant stakeholders, such as supply chain managers, industry experts, and consumers. The data collection techniques will involve conducting interviews, surveys, and analyzing relevant case studies. The qualitative approach will enable a comprehensive examination of the complexities and nuances associated with blockchain implementation and its impact on supply chain operations.

Supply chain management involves the movement of goods and services from the point of origin to the point of consumption. It is a complex process that involves multiple parties, including manufacturers, suppliers, distributors, retailers, and consumers. However, one of the main problems in supply chain management is fraud. Fraud can occur at any point in the supply chain, and it can take various forms, such as stealing, making fake products, or lying about the quality of products.

The traditional supply chain management system lacks transparency and accountability, which makes it difficult to prevent fraud. Companies rely on intermediaries to verify and track the movement of goods, but these intermediaries can be vulnerable to manipulation and fraud themselves. Therefore, there is a need for a more reliable and transparent system that can prevent fraud in the supply chain.

Fraud in the supply chain is a significant problem for many companies. Fraud can occur at any point in the supply chain and can take various forms, such as stealing, making fake products, or lying about the quality of products. Traditional supply chain management systems lack transparency and accountability, making it difficult to prevent fraud.

To address this problem, companies are increasingly turning to blockchain technology. By implementing a blockchain-based system, companies can track the movement of goods from the point of origin to the point of consumption, ensuring that the products are genuine and of high quality. The blockchain-based system also provides increased transparency and traceability in the supply chain, allowing companies to monitor the movement of goods and verify the authenticity of products at every stage of the supply chain.

However, implementing blockchain technology in the supply chain is not without its challenges. Companies need to ensure that all suppliers and intermediaries are onboard with the new system, and there may be a need for additional training to ensure smooth implementation. Additionally, companies need to consider the cost of implementing and maintaining the blockchain system, as it requires a significant investment of time and resources.

Overall, the goal of implementing blockchain technology in the supply chain is to prevent fraud and increase transparency, leading to better-quality products and increased customer satisfaction.

5.2 Justify The Problem:

For this research described above we can incorporate both qualitative and quantitative methods, making it a mixed-methods approach. For instance, the literature review can be conducted using qualitative methods to gather and analyze qualitative data such as expert opinions, case studies, and previous research. Data collection can also include both qualitative and quantitative methods, such as conducting interviews or surveys with stakeholders to gather qualitative data, and analyzing data from supply chain management systems to gather quantitative data. The data analysis phase can involve both qualitative and quantitative analysis techniques. For instance, qualitative data analysis methods such as content analysis can be used to analyze data from interviews or open-ended survey questions. Additionally, quantitative data analysis techniques such as regression analysis can be used to analyze data from supply chain management systems. The development and evaluation of the blockchain-based system would also require both qualitative and quantitative data. Qualitative data such as user feedback and usability testing can be used to improve the design of the system, while quantitative data such as system performance metrics can be used to measure the effectiveness of the system. Finally, the recommendations provided at the end of the research can incorporate both qualitative and quantitative insights gained from the various phases of the study.

5.5 Why This Approach is Fruitful for Satisfying The Hypothesis:

Implementing blockchain technology in supply chain management for ensuring the authenticity of products is a highly relevant and meaningful approach. This is because blockchain offers several unique features that can address challenges in supply chain management, such as lack of transparency, traceability, and accountability.

The proposed approach of using a unique block key for each product in the supply chain and linking it to the previous and next blocks creates an unalterable record of the product’s journey. By verifying three keys, the customer can confirm the authenticity of the product and its origin. This ensures that customers can trust the authenticity of the product they are purchasing, which can improve customer satisfaction and loyalty.

Furthermore, the use of blockchain technology can also reduce the risk of fraud and counterfeiting in the supply chain, which can help improve the overall integrity and reliability of the supply chain. This can be especially relevant for industries such as pharmaceuticals, luxury goods, and food products, where product authenticity and safety are of utmost importance.

Overall, implementing blockchain technology in supply chain management for ensuring the authenticity of products is a promising area for research, and can potentially offer significant benefits for both businesses and customers
