Blockchain technology is a transparent, decentralized digital ledger that tracks transactions across several computers. It was first created for cryptocurrencies like Bitcoin.

It is the perfect answer for improving traceability in the food industry because it offers an unchangeable, secure record of transactions. An array of blocks, each containing a list of transactions, makes up the distributed ledger known as blockchain technology. By utilizing cryptographic hashes to connect these blocks, a safe and impenetrable record of every transaction is produced. Blockchain technology can be used to produce an auditable, transparent record of food product movement throughout the supply chain in the context of food traceability.

Every transaction—including a change in location or ownership—is documented on the blockchain, resulting in an everlasting and unchangeable record. A single entity cannot control the entire system due to the decentralized nature of blockchain technology. Rather, a number of parties with access to the blockchain, including food producers, suppliers, distributors, and retailers, can confirm the veracity of the data entered. The enhanced transparency the food supply chain receives from using blockchain technology for food traceability is one of its main advantages. In order to ensure that there is no tampered or hidden data, a blockchain-based system allows all participants to access and verify the information recorded on the blockchain.

Customers are better able to make educated decisions about the food they eat because of this transparency, which also helps to foster consumer trust. Improved accountability in the food industry is another benefit of blockchain technology. In the event of a food safety issue, it is made simpler to determine the source of contamination or the accountable party by logging every transaction on the blockchain. Food manufacturers and suppliers are incentivized to uphold elevated benchmarks of quality and safety by this accountability. Also, the efficiency of tracking & tracing food products is enhanced by blockchain technology.

A blockchain-based system makes it possible to view a food product’s complete history in real-time, which facilitates prompt and precise determination of the product’s location or the source of contamination. This effectiveness aids in cutting down on the time and money needed for product recalls and inquiries. Walmart, IBM, and Tsinghua University worked together to carry out a pilot project aimed at showcasing how blockchain technology can improve food traceability. Monitoring mango shipments from Mexican farms to US Walmart stores was the project’s main goal. Throughout the trial project, every link in the supply chain—farmers, distributors, suppliers, and retailers—entered pertinent data about the mangoes onto the blockchain.

Details about the farm of origin, the harvest date, the mode of transportation, and the temperature during the trip were all included in this data. Consumers could access the blockchain and confirm the product’s authenticity and quality by scanning a QR code on the mangoes’ packaging. Customers were now able to follow the mangoes from the farm to the store, which improved supply chain transparency & investor confidence. Transparency, accountability, and efficiency in the supply chain are all improved by the inclusion of multiple essential features in Walmart’s blockchain-based food tracking system. First off, the system makes it possible for supply chain participants to share data.

Every participant can add pertinent details about the food products they handle & has access to the blockchain. There is less chance of misunderstandings or false information because of this shared database, which guarantees that all participants have access to current, accurate data. Second, food products can be tracked and traced in real time thanks to the system. Real-time data recording on the blockchain is possible with IoT devices and sensors, allowing for the recording of location, temperature, and humidity.

Ensuring the quality and safety of the products, this real-time tracking makes it possible to quickly identify any deviations from the necessary conditions. Finally, the blockchain offers unchangeable food product records. An entry into the blockchain cannot be removed or changed once it has been made. This function guards against fraud & tampering by guaranteeing the accuracy & legitimacy of the data that is recorded. Although blockchain technology has the potential to improve food traceability, as Walmart’s pilot project showed, there were a number of difficulties with its implementation.

Opposition from supply chain partners was one of the major obstacles. All supply chain participants must collaborate and participate in order to implement a blockchain-based system. It’s possible that some participants will be reluctant to use new technologies or will be wary of disclosing private information on a public blockchain. It will take cooperation & efficient communication between all parties involved to overcome this resistance. Implementing blockchain technology presented another technical difficulty.

Expertise in blockchain development & system integration is necessary to create a scalable and secure blockchain system. Ensuring compatibility between various blockchain platforms utilized by various supply chain participants can also be difficult. Last but not least, some businesses may find it prohibitive to adopt blockchain technology due to its cost.

A blockchain-based system’s development & upkeep demand a large financial commitment for software development, infrastructure, and continuing maintenance. For such an implementation, smaller businesses might find it difficult to set aside the required funds. For the food industry, Walmart’s experience implementing blockchain-based food traceability offers important lessons.

First and foremost, any traceability project needs the cooperation of supply chain participants to be successful. To guarantee the accuracy and integrity of the data recorded on the blockchain, all participants must be prepared to share information and cooperate. Overcoming any resistance or reservations can be aided by establishing explicit protocols & guidelines for data sharing. Second, in order for various blockchain platforms to work together, standardized data sharing protocols are necessary.

In order to record and share data on the blockchain, the food industry should endeavor to create uniform standards and protocols. Information sharing and smooth system integration will be made possible by this standardization. Finally, enhancing food traceability requires technological investment.
