A supply chain is a group of individuals and organizations engaged in the production, distribution, and customer service of a certain good or service. Supply chains are made up of raw material suppliers, factories that turn those resources into parts, assembly sites, facilities for storing and delivering items, retail establishments, and any other organizations that materially enable a company to supply goods and services to its clients. Modern global supply chains are crucial because they enable firms to acquire a greater range of components, goods, and materials at cheaper prices than they could with a localized supply chain. As a result, these companies can make more money and tap into new market prospects. Supply chains are frequently made up of several different countries, which makes them highly intricate. Supply chain management is the process of making supply chains as efficient as possible while lowering potential hazards within them. As a result, a sizable business has developed around it. Global supply chains still have a number of difficulties, some of which can be resolved with blockchain technology, despite all of their advantages. Increasing supply chain transparency is a prospective use for blockchain in supply chain management. Global supply chains are very opaque and prone to manipulation due to their inherent complexity. However, by using the distributed ledgers made possible by blockchain, organizations involved in a supply chain can build permanent records about the ownership and source of goods, resulting in a supply chain that is more transparent and effective. Additionally, since fewer internal audits are needed, businesses can devote valuable resources to tasks that are more beneficial. By utilizing smart contracts, the adoption of blockchain technology for supply chain management may also assist businesses in lowering their administrative expenses. Businesses may trace products through their supply chains and automatically determine ownership rights with the use of a smart contract system. Additionally, smart contracts can be set up to release automated payments upon delivery of products, eliminating the need for human administrators to manage payment processing. The ability of blockchain to interface with physical sensors to track transportation and storage conditions for sensitive products is a final crucial feature for supply chain management. Food-transfer trucks, for instance, can be fitted with sensors that keep an eye on the temperature to make sure the products are being transferred in the right storage conditions. Blockchain technologies give companies the ability to track the quality and handling of the commodities they are getting.
