Although initially developed for crypto$-$currency transactions, Blockchain is gradually expanding its applications to other domains. Blockchain implementation is associated with enhanced visibility, security, and effective supply chain management $($Ashcroft$,2024,$ para $7).$ Through a decentralized and immutable ledger of transactions, Blockchain guarantees that everybody in the supply chain can track products in real time and that the status updates.

The main plus point of Blockchain in supply chain management is the ability to trace transactions. Through Blockchain, every product can acquire a molecular digital identification and be recorded at any stage of its movement within the supply chain. This facilitates the understanding of how the end products are made and checks the authenticity and quality of products. For instance, a shopper can scan the QR code on the product and immediately be redirected to its country of origin, production methods, or the journey to the store shelves $($Straight $,2024,$ para $10).$

Blockchain boosts security in supply chain transactions because these records cannot be changed. Every block on the Blockchain brings the code and attaches it to the previous one, and there is no chance for third parties to edit or fake the data as well. It assures the protection of individuals against counterfeit goods, fraud, and unethical access to personal data.

Furthermore, blockchain technology enables efficiency by eliminating documentation and cutting paperwork costs. To begin with, supply chain transactions involve a lot of such documents in paper form as invoices, contracts, certificates, etc$($Straight $,2024,$ para $12).$ Through the digitation of those documents and actual recording on the Blockchain, the parties can expedite their process, eliminate manual errors, and speed up the movement of products through the whole supply chain.

The food sector could began with the Blockchain application in supply chain management for instance. Speaking of these two companies, Walmart and Nestle, they have already just adopted Blockchain to track the origin of foods in order to ensure food safety, as well as complying with the regulations. In addition, by means of blockchain, companies become more reliable and transparent in the supply chain, with a consequential decrease in malicious acts, such as foodborne diseases and product recalls $($IBM$,2023,$ para. $4).$
