Top 5 Use Cases of Blockchain in Supply chain
Supply chain based businesses integrating Blockchain technology into their operations gain greater transparency, traceability and efficiency throughout their supply chain processes. Read on till the end to explore the top 5 use cases of Blockchain technology in the supply chain.
Use cases of Blockchain in supply chain
1. Blockchain technology for food safety:

Blockchain for Food Safety is an innovative application of Blockchain technology in the food industry. it seeks to enhance the safety, transparency and traceability of the food supply chain. It addresses the challenges associated with foodborne illnesses, food fraud, and inefficient supply chain management. It addresses the concerns that are linked with foodborne infections, fraudulent food practices, and inadequate management of food supply chain.
Basically the old-style food supply chains involve several participants, including farmers, food processors, distributors, retailers, and consumers. As products pass through these multiple stages, important information about their source, handling, and quality can get lost or masked. It leads to difficulty in pinpointing the source and reason of contamination during foodborne disease outbreaks or identify fraudulent practices.
In the setting of food safety, Blockchain is a distributed and decentralized digital ledger that records transactions and data across a network of computers. Each participant in the food supply chain keeps a copy of the Blockchain, and any changes or additions to the ledger are verified and agreed upon by the consent among all participants.
Here is how Blockchain ensures food safety:
Food Recall Management:
When there is any problem or concerned found with the safety of food, Blockchain makes it possible to return it without any delay. The exact point where the problem arose can be detected with the technology of Blockchain. The efficiency of Blockchain makes the process of product recalling shorter and cost effective.
Quality Assurance:
On the Blockchain, product data is recorded to ensure its quality. The information may include, temperature, humidity, and other environmental factors during shipping and storage. The data help in maintaining the quality and safety of perishable food items.
Regulatory Compliance:
Blockchain can help with legal compliance by recording a clear and auditable record of how food safety practices are carried out. This helps the companies to present that they abide by the law.
Consumer Confidence:
As the consumers have detailed and transparent information of the food, from its origination to its destined store, consumers can make more informed choices. It leads to consumers’ confidence in the food supply chain.
2. Blockchain technology for Diamond Tracking

Implementing Blockchain technology is an advanced and more accurate solution to enhance the transparency and trust in the process of diamond supply chain. It addresses the issues that are associated with the provenance and originality of diamonds. Blockchain technology helps to ensure that diamonds involved in the supply chain are sourced ethically and come from conflict free regions. Here is how it works:
Data Entry:
At the start of the supply chain, each diamond is given an identification code that is shown as a digital currency or smart contract on Blockchain. That code has important information about the diamond like the origin of the diamond, its weight, cut, color, clarity and what certifications it has.
Decentralization & Consensus:
Blockchain runs on a decentralized network of computers called nodes. In order to add a new block into the chain, a consensus mechanism like Proof of Work (PoW) and Proof of Stake (PoS) is used to validate the transaction. This makes sure that the data is correct and cannot be tampered. Since anyone trying to tamper the information must have control on majority of the network, which is almost impossible in a robust Blockchain system.
Ethical Sourcing & Sustainability:
Blockchain technology can also be used to ensure that diamonds are sourced legally and ethically. Moreover, it helps in assuring that diamonds are mined in compliance with environmental and labor standards.
3. Offering tracking information to customers:

Blockchain technology was being explored and implemented in various industries including supply chain management and logistics. Since then, people are still figuring out how to use it, and its various unimaginable attributes are coming on the way to its users. Blockchain is used to provide product tracking services to customers. Here is how it is done:
Launch a Blockchain Network:
First, choose a suitable Blockchain platform that fits the need. Popular options are Ethereum, Corda and Hyperledger. Create a grouped or private Blockchain network with the relevant parties such as producers, distributors and consumers.
Digitize the Supply Chain:
Make sure the whole process of the supply chain is digitalized. It is necessary to capture and record important data at each step.
Assign Codes:
Assign unique codes to each product or batch. These codes will be recorded on the Blockchain. It will allow the customers to track the status of their product using the code.
Recording Tracking Information:
On every step of the supply chain, record relevant tracking information on the Blockchain. This include location, time and condition of the product.
4. Blockchain technology in Oil supply chain:

In the oil and gas industry, Blockchain has the capacity to disrupt numerous areas that may include supply chain, compliance, and data management and so on. Discussing about only supply chain, Blockchain has immensely improved the complex supply chain of oil and gas industry.
As the parties involved in the supply chain of oil and gas industry often located in different countries running different systems. So traditionally it was very challenging to manage supply chain in this industry. The complicated nature of oil and gas, involvement of intricate processes and involvement of multiple parties often leads to inefficiencies and delays.
But with the implementation of Blockchain technology in their systems, companies can make a decentralized and transparent ledger. That record every transaction, ensures traceability and eliminate frauds and scams.
5. Blockchain technology in Wine supply chain:

Many times, wines contain some additives that can be damaging for the health of consumer. These fruadulent practices are very common and also very hard to detect and eliminate. However with the integration of Blockchain technology, the companies can detect the contamination and deal with it on the right time.
Product Recall Management:
Blockchain makes it possible to return wine right away if there is a problem. Using Blockchain technology, you can find out exactly where the trouble started. The efficiency of Blockchain makes product recalls more efficient and cost-effective.
Quality Assurance:
On the Blockchain, details about a product is kept to assure its quality. The information may include grape variety, additives, chemical content etc. The information helps maintaining the quality of the product.
Conclusion:
The advanced solutions that Blockchain technology is continuously providing to all the industries are not easy to ignore. The implementation of Blockchain in supply chain management is bringing tremendous outcomes in the field of supply chain and logistics. It is a system for every step of SCM. A huge number of industries are shifting to better management with the help of Blockchain and many more are considering to implement it.
