Blockchain Technology Implementation in Supply Chain Management: A Literature Review

Abstract

This paper aims to comprehensively review the main benefits, limitations, and challenges associated with the uptake of Blockchain technology in supply chain management (SCM). The study utilizes the literature review method, examining articles published from 2016 to 2022 and exploring the factors influencing the adoption and implementation of Blockchain in SCM. Multiple scholarly insights have shown no more hacking or cherry picking of options given for presenting data with high confidence and, therefore, reliability, as well as an ability to see everything in a highly limited way. An SCM looking at these multi-party evolutionary models shows that for Blockchain, the key advantages center on significantly increased security, confidentiality, traceability, transparency, data accuracy, privacy, efficiency, accountability, and trust. In contrast, the review has also detailed several limitations and challenges that must be overcome by firms and industries looking to adopt Blockchain within their SCM processes, which include problems with scaling, lower performance as a result of interoperability issues, legal and regulatory matters, very high initial implementation and ongoing maintenance costs, a struggle with standardization of the technology and the needed surveillance of this space, avoidance of technology adoption because of trust, the substantial energy used, low awareness, complexity of integrating with existing systems, being in its last mile in partnerships, and privacy. Even with this potential to transform and be disrupted across industry and its sectors, there are still very significant challenges for Blockchain. For those looking to actually utilize SCM and other sectors, understanding this from a variety of perspectives is of great interest to understand if the technology is fit for that sector and what strategies or networks need to be established or linked into with existing firms. Regardless, if these challenges can be overcome and responded to, then the greater protection and efficiency of current and future SCM processes will not only occur, but it can be the first significant node for broader industry-wide innovation and gains in efficiency.

1. Introduction

1.1. Blockchain Background

At the beginning of the 1990s, Scott Stornetta and Stuart Haber developed a secure document timestamping mechanism that laid the foundation for Blockchain technology. Later, Nick Szabo expanded on this idea and created a decentralized and secure ledger called “bit gold”. These early attempts at developing secure and decentralized systems led to the development of Blockchain technology [1]. The concept of “Smart Contracts” has been introduced by Nick Szabo to bring the advanced experience of contract law of designing electronic commerce protocols between the Internet and strangers. He first introduced this idea in 1994, and in 1996, he explored the potential of smart contracts. Szabo envisioned a digital marketplace based on automatic, secure processes that would enable trustless transactions and business functions without intermediaries. Today, the Ethereum Blockchain offers an example of smart contracts in action, as its team has implemented Szabo’s vision [2,3]. In 2008, an unidentified group or individual using the nickname Satoshi Nakamoto issued a white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” that suggested a decentralized digital currency that could be exchanged securely without intermediaries like banks. The technology behind Bitcoin, called Blockchain, provides a secure and decentralized ledger of all transactions. Despite many claims, the true identity of the person or group that authored the original Bitcoin white paper in 2008 using the pseudonym “Satoshi Nakamoto” remains a mystery. Until 2011, Satoshi was actively engaged with the Bitcoin community through online forums and email correspondence, but then suddenly disappeared and passed on control of the Bitcoin code to other developers. Satoshi’s impact on the development and direction of the cryptocurrency industry has been substantial and far-reaching, as noted by the authors of “Bitcoin and Cryptocurrency Technologies” [4]. Finally, the period between 2014 and 2015 was a significant milestone in the history of Blockchain technology. During this time, there was a widespread understanding of Bitcoin, a cryptocurrency that employed Blockchain technology. However, it became increasingly apparent that Blockchain technology could be utilized for more than predicted. One of its uses can be in supply chain management (SCM) to monitor and control entire processes, functions, and phases of SCM.

Therefore, this paper aims to provide a comprehensive overview and critical analysis of the previous literature on the usage of Blockchain technology in the context of SCM. The paper’s objectives are to revise and analyze the existing literature on the usage of Blockchain technology in SCM, to identify the main benefits, limitations, and challenges facing Blockchain technology in SCM, to explore the factors that affect the adoption and application of Blockchain technology in SCM, and finally, to provide recommendations for supply chain players and for future research on the usage of Blockchain technology in SCM. Therefore, the current article’s goal is to respond to the following questions:

Q1: What are the main applications of Blockchain technology in SCM?

Q2: How effective is Blockchain technology in improving SCM transparency, security, and efficiency?

Q3: What are the key challenges and limitations of Blockchain implementation in SCM?

Q4: What are the factors that influence the adoption and implementation of Blockchain technology in SCM?

Q5: What are the main findings and themes that emerge from a comparison of the literature on Blockchain in SCM?

This paper is one of the few papers which discuss using Blockchain technology in SCM to increase transparency, security, and efficiency of SCM. The results will be beneficial not only for SCM practitioners but also for academicians, who are concerned about both Blockchain technology as well as SCM.

1.2. Overview of Blockchain Technology and Its Key Features

The technology behind blockchain has advanced, and its uses have gone beyond the realm of cryptocurrency markets. At the moment, it is used in a variety of domains, including voting processes, supply chain management, digital identity management, and so on. As a result, a number of firms have been undertaking trials with Blockchain technology for a variety of objectives, including decentralized markets, identity verification, and supply chain management. The initial purpose of Blockchain was to merely offer a decentralized ledger for the purpose of recording transactions. This was a significant departure from the original function of Blockchain. The word “Blockchain” has become increasingly prevalent in conversations about technology as a result of the growing number of companies that are investigating the possibilities offered by Blockchain technology. The community around Bitcoin was becoming more concerned about the possibility that the technology was being appropriated by other use cases. Many individuals were concerned that the increased attention paid to Blockchain may result in a decrease in the value of Bitcoin and other cryptocurrencies. The rising understanding that Blockchain technology might have potential applications beyond simply cryptocurrencies finally led to the separation of Blockchain and cryptocurrency. This eventual split was ultimately the result of this recognition. In the modern world, a great number of organizations are beginning to investigate the possibility of using Blockchain technology in a variety of applications, including digital identity verification, supply chain management, and voting systems. While this is going on, cryptocurrencies such as Bitcoin are still being used as a kind of decentralized money and as a way to store value [5].

Blockchain technology is a very innovative notion that is bringing about a change in the manner in which we record and verify data and transactions. This forward-thinking technology comprises a number of essential components, all of which should be brought to the attention of people and organizations in the future. The following is a list of the five most critical aspects of Blockchain technology that should be well-understood:

(1)

The notion of several distributed ledgers: This is an essential component of Blockchain technology, characterized by the use of a decentralized and distributed database for the purpose of recording transactions and other important data. The distributed ledger makes it possible to record data in a way that is both transparent and safe since it eliminates the need for intermediaries and/or central authorities. The ledger is constructed of “blocks” that are connected to one another in the form of a chain, with each new block being added to the end of the progression of blocks. A permanent and unchangeable record that is readily traceable and verifiable is produced as a result of this action [6]. A central authority does not have control over the ledger since the Blockchain is decentralized, which means that it is not centralized. A network of nodes, on the other hand, collaborates in order to verify each transaction and ensure that the ledger is consistent throughout the network. The Blockchain is more secure and resistant to tampering than a centralized system because it does not have a single point of control that is centralized [7]. The idea of a decentralized ledger has been used in a variety of contexts, including the use of cryptocurrencies like Bitcoin and applications such as voting systems, supply chain management, and digital identity verification. Without the need for a centralized authority, the Blockchain ensures a transparent and safe method of storing information and authenticating transactions. This is the case in every scenario. In the case of Bitcoin, for instance, the Blockchain is used to record the ownership of each unit of the cryptocurrency as well as the transactions that occur with it. In supply chain management (SCM), the Blockchain is used to guarantee the authenticity of the product and to avoid counterfeiting. Voting systems may benefit from the Blockchain’s ability to offer a record of votes that is both transparent and verifiable. In conclusion, the decentralized ledger that Blockchain utilizes is a concept that is both novel and possibly revolutionary, and it has several applications in a broad variety of sectors. Recording and confirming transactions and other data without the need for a central authority is made possible by its security, transparency, and tamper-proof nature, which makes it an appealing alternative [8].

(2)

The use of the permissionless method: This is yet another essential component of Blockchain technology that makes it possible for anybody to take part in the Blockchain network and carry out transactions without the need for authorization from a centralized authority. The fact that this makes it possible for anybody to engage and contribute to the network makes it more democratic and accessible. As a result, the network is available to everyone, regardless of their location in the world, their social standing, or their political allegiance. Traditional centralized systems, in which access to the system and the capacity to carry out transactions are regulated by a central authority, stand in striking contrast to the permissionless nature of Blockchain technology, which is also known as distributed ledger technology. The openness and accessibility of the Blockchain network make it possible to take a more democratic approach to the processing of transactions and the management of data [9]. In addition, the permissionless technique is essential for the security and transparency of the Blockchain network. When using the permissionless technique, it is far more difficult for a single organization or group to exert control over the data or manipulate the system. Rather, the network is maintained and updated by a wide and varied community of users who collaborate to authenticate transactions and ensure the consistency and quality of the data. This community is responsible for maintaining and updating the network. In general, the permissionless method is an essential component of blockchain technology, which offers a more democratic, accessible, and safe approach to the processing of transactions and the administration of data. The permissionless approach is increasingly likely to play a big role in promoting innovation and development in a variety of sectors and applications [10]. This is because Blockchain technology is improving and becoming more widely embraced.

The encryption system, which is regarded as an essential component of Blockchain technology, plays a significant part in ensuring that the network continues to possess both security and privacy considerations. It is a process that includes the use of intricate mathematical techniques and protocols to encrypt data and transactions in order to render them resistant to efforts to compromise or hack the system. After going through this procedure, the data that are saved on the Blockchain are guaranteed to be safe, secure, secret, and dependable [11]. Cryptography is a method of data protection that uses a mix of encryption and hashing techniques. The process of encrypting data involves scrambling the data with a secret key in such a manner that only those who possess the key that corresponds to the data may read it. On the other hand, hashing allows the data to be transformed into a one-of-a-kind string of characters that is fixed in length. This string serves as a digital fingerprint of the data that were initially stored. Any modifications that are made to the data will result in a different hash value, which makes it simple to identify any efforts at human intervention [4]. Additionally, the use of encryption in Blockchain technology ensures that the transactions are carried out in a manner that is transparent and secret. Given that transactions are encrypted, the identities of both the sender and the recipient are safeguarded, thus guaranteeing that privacy and secrecy are maintained. In the field of cryptography, the use of both private and public keys guarantees that the transaction may only be accessed by the intended receiver, hence preventing any unauthorized access or interception from occurring [12]. To summarize, the cryptography scheme is an essential component of Blockchain technology that safeguards the network, protects users’ privacy, and ensures its dependability. By using encryption and hashing, the data that are stored on the Blockchain are guaranteed to be safe, secure, and resistant to tampering. Additionally, the use of public and private keys guarantees the secrecy of the data and guarantees that only authorized individuals may access it.

When it comes to Blockchain technology, it is essential for all nodes in a dispersed network to reach a consensus on a single version of the truth, which is then recorded in the ledger. Nevertheless, since the network is decentralized, it is conceivable for there to be inconsistencies or inaccuracies in individual copies of the ledger. This will occur because of the structure of the network. The tactics of reaching a consensus come into play at this point. Consensus methods are used in order to establish a consensus among the nodes on the current state of the ledger, despite the fact that there may be inconsistencies or mistakes that may be present. Using consensus techniques, which are meant to verify transactions and guarantee that all nodes have the same version of the ledger, is the means by which this objective is accomplished. In addition, algorithms are used to prevent malicious conduct, such as double spending, and to ensure that the system continues to be secure [13]. There are several different kinds of consensus algorithms that are used by Blockchain technology. Proof-of-Stake (PoS), Proof-of-Work (PoW), and Delegated Proof of Stake (DPoS) are some examples of these cryptocurrency protocols. Nodes are required to discover answers for difficult mathematical problems, verify transactions, and generate new blocks in order to participate in the Proof-of-Work process, which is a computationally expensive method. On the other hand, Proof-of-Stake (PoS) is an algorithm that requires nodes to keep a particular amount of bitcoin as a stake in the network. This method takes less energy than Proof-of-Stake (PoS). Last but not least, decentralized proof-of-stake (DPoS) is a version of Proof-of-Stake (PoS) that employs a voting method to evaluate which nodes are accountable for verifying transactions [14]. Through the use of consensus algorithms, Blockchain technology has the capability to guarantee that all network nodes that have been agreed upon are in the same state of the ledger and that there is no malicious activity taking place. This not only helps to maintain the system’s security and integrity, but also makes it possible to create a network that is decentralized, trustless, and able to function normally without the need for intermediaries.

It is possible to build self-executing agreements with pre-programmed rules and conditions via the use of smart contracts, which are an essential component of the infrastructure that underpins Blockchain technology. Through the process of automatically matching transactions and processes on the Blockchain, smart contracts enhance efficiency, speed, and security, respectively. In an environment that is trustless and decentralized, smart contracts make it possible for parties to execute agreements without the need for intermediaries or central authority. This enables them to minimize costs and enhance transparency. They are supposed to be self-executing, which means that when certain criteria are fulfilled, they automatically activate the action that was agreed upon [15]. They are programmed in programming languages and are designed to behave in this manner. The adaptability of smart contracts makes it possible to employ them in a wide variety of different contexts. The execution of financial transactions, the facilitation of the acquisition and transfer of assets, and the automation of supply chain management are all capabilities that they possess. Moreover, they are being investigated in a variety of other industries, including the medical profession, the real estate industry, and the legal services sector. In general, smart contracts are an essential component of Blockchain technology. They make it possible to automate transactions and other operations, which ultimately leads to increased efficiency, speed, and security. The relevance of smart contracts in contemporary technology is shown by the fact that their potential to revolutionize a variety of different sectors is continuing to grow [16].

In conclusion, it is essential for people and organizations who want to make the most of the potential offered by Blockchain technology to have a solid grasp of these five primary components of the technology. It is quite probable that the technology known as Blockchain will play a significant part in the development and implementation of a wide range of businesses and applications in the not-too-distant future. Individuals and organizations are able to reap the benefits of the many advantages offered by Blockchain technology if they have a solid grasp of these components.

2. Materials and Methods

To address these concerns, we conducted a thorough review of the relevant literature to explore how Blockchain technology is applied in supply chain management. A set of criteria was used to select papers, including relevance to the topic, publication date, and study methodology. Search terms like “Blockchain”, “supply chain management”, “distributed ledger technology”, and “smart contracts” were employed. The information was gathered by searching various academic databases such as Google Scholar, Scopus, and Web of Science. The search yielded 23 research articles published between 2016 and 2022 that focused on the use of Blockchain technology in supply chain management.

Next, the selected publications were evaluated against the inclusion criteria, resulting in a total of twenty-three articles being selected for inclusion in this research. For data extraction, the authors, the year of publication, the research questions, the methodology, the kind of Blockchain technology that was used, and the industry that was examined were all recorded. A content analysis technique was employed to compare the selected articles. These articles had to meet specific criteria: (1) focus on Blockchain technology in supply chain management; (2) be published in peer-reviewed scientific journals; (3) be written in English; and (4) be published between 2016 and 2022.

Strategy for Searching: To conduct a comprehensive search, a combination of keywords and filters was employed across four electronic databases: Scopus, Google Scholar, Web of Science, and IEEE Xplore, along with several other academic databases. Search terms like “Blockchain”, “Blockchain technology applications”, “Supply chain management”, “Supply chain optimization”, “Distributed ledger technology”, “Decentralized ledger technology”, “Smart contracts”, “Ethereum smart contracts”, “Smart contract technology”, and “Decentralised systems” were utilized. The search was limited to articles written in English and published between 2016 and 2022.

Extraction of Data: The data for this study were extracted from each article using a standardized form with fields for the names of the papers, authors, publication years, purposes, methodologies, applications, limitations, primary focuses, and key findings. Five main aspects were used to extract the data: (1) the goal of the research, which compared the primary purposes or objectives of each study, such as analyzing the benefits of Blockchain technology in supply chain management (SCM) or exploring potential difficulties and risks associated with its implementation; (2) methodology, which compared the research methodologies used in each paper, ranging from case studies or surveys to a more theoretical approach; (3) applications, which examined the various uses of Blockchain technology in the supply chain management sector, including ensuring traceability and transparency in food supply chains or its application in supply chain finance or logistics; (4) challenges, which identified obstacles and constraints related to the application of Blockchain technology, such as interoperability of different Blockchain systems and data security and privacy; (5) key results, which presented the most significant findings, conclusions, and implications of the research, providing a condensed overview of the most important and relevant information. The data extraction was performed independently by both researchers, and any inconsistencies were resolved through discussion.

Anyway, Blockchain technology has the potential to enhance several fields, such as finance, government, healthcare, and SCM, by bringing decentralization, security, transparency, and efficiency.

However, to fully achieve its promise, problems such as scalability, interoperability, regulation, and difficulties in application have to be overcome. For instance, Blockchain technology can assist supply chain managers in improving transparency, accountability, and traceability, but businesses need to carefully consider its implementation due to obstacles that may arise.

Studies have shown that Blockchain technology has the potential to provide transparency, traceability, and safety in the food sector, but technological, economic, and regulatory issues must be resolved for it to fulfill its potential. Similarly, Blockchain technology can enhance supply chain traceability, and while there are advantages, deployment may be challenging.

Several studies have focused on the usage of Blockchain technology in SCM, with various methodologies and focal points. These studies offer different viewpoints, highlighting the possible advantages and difficulties of applying Blockchain technology in SCM. Evaluating Blockchain applications and analyzing their essential elements, possible advantages, and adoption obstacles is essential in determining their effectiveness in enhancing efficiency and security in SCM. Blockchain holds significant promise as a transformative technology for various industries, including finance, government, healthcare, and supply chain management (SCM). However, realizing and maximizing its potential requires addressing important challenges, such as scalability, interoperability, regulation, and application challenges. Blockchain has the potential to decentralize, secure, and make processes transparent, which could present a disruptive force against established legal systems and regulatory frameworks, leaving open how such a shift would be treated and/or managed within a legal framework.

Despite these challenges, Blockchain can offer decentralization, security, transparency, and other advantages that make it an appealing solution for many industries. For SCM, case studies and proofs of concept have been provided in support of Blockchain’s ability to significantly enhance traceability, transparency, and authenticity. However, challenges stand in the way of realizing the technology’s transformative potential.

As one analysis concluded, Blockchain can enhance transparency, traceability, and safety in the food sector, particularly in the face of a recall. However, technical, economic, and regulatory challenges must first be resolved to leverage Blockchain to its full potential. On the topic of traceability more broadly, every implementation of Blockchain for supply chain purposes introduces its own advantages and challenges.

Further research into the application of Blockchain to SCM has produced critical findings with regard to different systems, the value proposition of particular systems, and the impediments to their adoption. This may be considered essential reading to assess the extent to which Blockchain can, in fact, enhance SCM, and how to best conceive of its implementation.

In summary, while Blockchain technology has the potential to revolutionize various industries, there are still several issues that need to be addressed to fully realize its potential. Understanding the benefits and difficulties of applying Blockchain technology in different industries, including SCM, is essential in determining its effectiveness and the different strategies needed to assess its application and implementation.
