Blockchain In Supply Chain Management

Blockchain In Supply Chain Management

Supply chains have grown into complicated networks comprising various players in the intricate web of contemporary business, from raw material suppliers to end customers. However, the issues of transparency, traceability, and trust within these networks have driven the development of novel solutions. Enter blockchain technology, a ground-breaking notion with the potential to transform supply chain management as we know it. This article digs into the relevance of blockchain in supply chain management, clarifying its benefits, real-world applications, and future possibilities.

What Is Blockchain Technology?

Blockchain technology is a decentralized and secure digital ledger system that records transactions across multiple computers. Each transaction, or "block," is linked and secured using cryptographic principles, forming a chronological chain of data. This structure ensures transparency, as every participant can view and verify transactions, reducing the need for intermediaries.

The consensus mechanism, often proof of work or proof of stake, ensures agreement on the state of the ledger, enhancing security and preventing tampering. Blockchain has applications beyond cryptocurrencies, such as supply chain management, voting systems, and identity verification, due to its immutability and tamper-resistant nature. Its potential lies in providing trust, security, and efficiency in various industries by transforming traditional processes and fostering innovation.

What Advantages Does Blockchain Technology Provide Supply Chains?

Blockchain technology is a type of distributed ledger. In this ledger, transactions are stored as a chain of code blocks. When the blockchain updates, every computer with the same ledger is updated. This implies that because each block only exists in reference to its preceding and following blocks, the data within a block cannot be modified. As a result, blockchain is now a highly verifiable, anti-tampering, and transparent technology in business, particularly in supply chain management.

Now we can concentrate on the benefits that blockchain technology delivers to supply chains. Here are several fundamental ones that have been overlooked.

Traceability: Because of its integrated and all-encompassing linking of operations, blockchain makes it simple to track and visualize processes in a supply chain. This improves the traceability of each component of a supply chain, such as keeping track of supplier information, procurement, and delivery of items, among other things.

Transparency: Another advantage of blockchain is that it fosters trust among the stakeholders involved in a supply chain by allowing open access to crucial data points. Its traceability also adds to its transparency.

Speed: A blockchain incorporates smart contracts, or portions of code, within a single block. When preset requirements of the actions are satisfied, smart contracts automatically update the activities. This feature allows for the replacement of sluggish and manual operations that need time-consuming confirmations.

Immutability: Because blockchain is a distributed ledger with several copies, it is nearly hard to tamper with a given transaction because one must change all copies at the same time. As a result, blockchain adoption in the supply chain is very reliable and resistant to fraud.

Consensus: For transactions to properly follow one another within a supply chain, all parties must agree on the activities. Work is impossible to do without agreement. Blockchain is also useful for achieving and maintaining process consensus because all stakeholders are aware that the transactions are automated and legitimate.

Use Cases Of Blockchain Technology In Supply Chain

Although it is too early to claim that blockchain technology will rule supply chains, firms are exploiting it in various areas and stages of their supply chain. We can identify a few blockchain supply chain use cases:

1. Supply Chain Management (SCM)

Supply Chain Management refers to the end-to-end coordination and optimization of processes involved in the production, procurement, distribution, and logistics of goods and services. It encompasses the planning, execution, and monitoring of activities that ensure the efficient flow of materials, information, and finances from suppliers to consumers. SCM aims to enhance operational efficiency, minimize costs, reduce inventory, and improve overall customer satisfaction.

Key components include demand forecasting, inventory management, supplier relationship management, transportation logistics, and technology integration. By fostering collaboration among stakeholders, SCM enables organizations to respond swiftly to market changes, mitigate risks, and achieve competitive advantages in today's global and interconnected business landscape.

2. Cost Lowering

Cross-border transactions are possible using blockchain. As a result, firms may avoid using intermediaries. They save not just time but also money by eliminating excessive expenditures associated with intermediary stages.

3. Product Recall Regulation

Blockchain facilitates the identification and location of impacted items in the process, making it easier for supply chains to control product recalls due to its traceability and transparency. As a result, the remembering process becomes less costly and more efficient.

4. Reducing Counterfeiting

Provenance is essential for product quality and dependability evaluations. Because blockchain provides for the traceability of every stage in a supply chain, the provenance of items may be properly confirmed. As a result, it aids in the reduction of counterfeiting by providing a rapid assessment of the source of suspicious items. According to OECD research, counterfeit and pirated items accounted for 3.3% of global commerce and 6.8% of total EU imports in 2016. This suggests that there is an urgent need to prevent counterfeiting, which blockchain technology may do.

Furthermore, because every transaction is subject to verification, blockchain can help to combat documentation fraud by verifying certificates and legitimate papers.

5. Maintaining Ethical Standards

Consumers are becoming more conscious of the ethical standards they expect from the firms from whom they purchase their goods. Before purchasing from a firm, 60% of customers say they look for brands that match their own values of sustainability and purpose, and they conduct research on the company's environmental, social, and governance (ESG) activities.

As a result, customers demand assurance that the items they purchase are not subjected to unethical manufacturing and distribution practices. They may learn about the source of their items as well as how they are created and distributed thanks to blockchain traceability.

6. Logistics

We have discussed the usage of smart contracts in blockchain technology. Transactions may be verified, documented, and coordinated automatically using these smart contracts. As a result, the complexity of global supply networks is reduced. Some logistics corporations, such as DHL, are considering incorporating blockchain technology into their operations.

7. Payments to Suppliers

As previously said, blockchain transforms transaction traceability. Payments are a component of this. Because blockchain enables autonomous control of verified procedures through smart contracts, supplier payments are completed faster and with less intermediary participation once requirements are fulfilled.

8. Food safety

The food business is considering blockchain for the health of the food supply chain. For example, Walmart, in conjunction with IBM, utilizes blockchain technology to track the source and quality of its Chinese pork supply. Increased traceability makes it easier for food supply networks to:

  • Avoid tampering with food origin data.
  • Prevent contamination of provided items through a speedier and more controlled process between the processor and the distributor.
  • Stop product spoilage between the distributor and the store.

9. Post-sale Services

Post-sale services such as warranties and maintenance can become more trustworthy and under control with the digitization of product information via blockchain. When a buyer certifies the digital identification of a product, the warranty term may begin automatically. Furthermore, second-hand consumers may research the product's distinctive identification with confidence, making second-hand trading more trustworthy.


Incorporating blockchain technology into supply chain management offers a transformative solution for enhancing transparency, traceability, and efficiency throughout complex global supply networks. By providing an immutable and tamper-proof ledger, blockchain ensures data integrity and builds trust among stakeholders. Real-time visibility into the movement of goods, automated smart contracts, and streamlined documentation processes contribute to reduced delays, fraud, and errors. Blockchain's potential to revolutionize supply chain management lies in its ability to create a secure, decentralized, and interconnected ecosystem that benefits manufacturers, distributors, retailers, and consumers alike.
