The Impact of Blockchain Technology on Supply Chain Management

Supply chain management is a broad field that has changed radically over the past decade due to globalization, technological advancements, and increasing consumer demands, reshaping the flow of goods and information. Blockchain technology is one of the most disruptive and is a decentralized, immutable, and transparent software platform explicitly designed to facilitate cryptocurrencies. It has drawn significant attention in supply chain management due to its high likelihood of addressing the issues that have long prevailed in supply chain relations, such as information asymmetry, inefficiency, counterfeiting, and lack of traceability. Blockchain also establishes a context of trust and accountability without necessarily involving centralized intermediaries, as transactions become visible in a distributed registry accessible to the signatory members. The current essay explores the impact of blockchain in supply chain management regarding security, traceability, transparency, operating efficiency, and the issue of its deployment.

Enforcement of transparency and traceability is one of the best-known uses of blockchain in supply chain management. The supply chains in the traditional supply chain are mostly non-navigable, resulting in the inability of parties concerned to track the products imparted where they end up. Unable to answer this question, blockchain develops an immutable record of every movement and transaction made and grants its actual users access to live information regarding product provenance, production cycle, transportation, as well as certifications (Cole et al., 2019). This transparency is also fundamental in the business industry, where individuals have considered the role of safety and authenticity, including food and pharmaceuticals. As a case in point, Walmart partnered with IBM to deploy blockchain-based monitoring throughout its food supply chain, enabling the company to make findings about polluted merchandise within several seconds instead of weeks (Chang et al., 2019). It would not only increase the antagonism towards consumer power, but also decrease the size of the product recall, which secures the well-being of the population and the authority of the business image.

Along with traceability, blockchain enables the digital creation of the passport of digital products, which consists of a significant part of information on the sourcing, environmental results, innovating work practices, and legislative promises (Batwa & Norrman, 2020). These electronic records help buyers make good purchasing decisions and demonstrate how they put sustainability and ethics into their supply chain relationships. This position would be after the augmented consumer need for prudence about corporate social responsibility and sustainable energy supply. Consequently, blockchain contributes to making the operations more efficient and assists in building brand confidence and competitiveness in the market.

The other highlights of blockchain in supply chains are that people are offered a high degree of security and less counterfeiting. Transformational supply chains are prone to fraud, data malfunction, and follow-up infiltration of the fake products, which result in significant economic losses. The blockchain databases are immutable, meaning a footprint might be left rather than removed when information is written to the blockchain (Wang et al., 2019). This feature offers an excellent resistance against falsification and inaccessible modifications. Using distinct digital identities to identify products, companies can verify goods during the whole distribution process, and it is virtually impossible to introduce fake items into the circles of people and accept them as legal goods (Goyat et al., 2019). Manufacturers of luxury devices, pharmaceutical companies, and technology producers have started to use blockchain to protect their products against faking, protect their blood, and maintain the quality of their brands.

Besides fixed records, blockchain also allows the implementation of smart contracts and self-executing agreements that are eventually coded in a computer language. Smart contracts automatically comply with the established terms, including the release of payments, in case of delivery confirmation, or inventory changes, in case the quantity decreases below a certain level (Wang et al., 2019). Smart contracts can significantly improve the processing of transactions by reducing the chances of mistakes and fraudulent practices and reducing the amount of human intervention. Such security and automation make the process of supply chains easy, reduce the administrative expenses, and strengthen the confidence of all stakeholders.

Blockchain has a considerable impact on operational efficiency and cost reduction. Historical supply chains typically involve various intermediaries, which may be disorganized, inefficient, and slow. The peer-to-peer model of blockchain allows for the elimination of intermediaries and helps to facilitate direct transactions between parties (Gurtu & Johny, 2019). This disintermediation is not only seen to reduce costs but also to hasten information and products. Due to automation, smart contracts promote factor efficiency by removing manual processes. For example, shipment payments can be automatically processed upon delivery, eliminating the need to create additional administrative overhead and accelerating payments.

Blockchain-based real-time data sharing is also beneficial for demand forecasting and inventory control. Blockchain enables companies to detect the source of bottlenecks, streamline supply chains, and streamline their procurement plans, as they can access the correct and updated information regarding the movement of products (Cole et al., 2019). Improved forecasting decreases waste, the cost of holding inventory, and customer satisfaction, as the product's availability is guaranteed. Through this, blockchain helps organizations to make evidence-based decisions to make markets more responsive and competitive.

Despite all the positive advantages listed, blockchain in the supply chain approach is coupled with colossal issues and drawbacks. Another pressing issue is scalability, and most blockchain networks cannot cope with the scale and speed required in large global supply chains (Saberi et al., 2019). This reality creates doubts, such as the impossibility of implementing the whole system of the blockchain to substitute the existing central systems that are not the most efficient. Moreover, the relationships with other architectural elements, such as existing enterprise resource planning systems, are both technically challenging and costly in most scenarios and demand a substantial change process (Goyat et al., 2019).

Another obstacle that can break up the operations of supply chains and decrease the performance is the lack of cohesive procedures and interference of several blockchain systems (Batwa & Norrman, 2020). It is also a problem because of a lack of shared norms that make cooperation in industries and nationally difficult. Besides, environmental impacts related to one type of blockchain consensus mechanism, such as proof of work, are also an environmental concern. Compared to business strategies of reducing carbon footprints, such processes are energy-focused (Kouhizadeh et al., 2021). Organizations, in turn, are taking more environmentally-friendly alternatives, likely to result in less environmental impact in the form of proof-of-stake. Overall, the blockchain can offer radical abilities to supply chain management and make the supply chain more transparent, traceable, secure, and efficient.
