Supply chains aren’t just limited to manufacturers and distributors. Rather, you will come across numerous other entities forming crucial pillars to make the ecosystem work—including retailers, logistic providers, suppliers, regulators, and even consumers. There’s no doubt that the market has now become more globalized, complex, and interdependent. In this scenario, maintaining efficiency, trust, safety, and transparency is no longer achievable overnight. In fact, it demands technological advancements that can shatter the shackles of legacy systems.
This is where blockchain in supply chain enters the picture! It brings numerous benefits to the table for everyone involved in the ecosystem. Immutability, transparency, automation, and consensus are a few to name. That being said, the following blog will further explore what blockchain brings to the supply chain market.
Key Use Cases of Blockchain in Supply Chains
Provenance Tracking/end-to-end Transparency
Every product changes too many hands along the entire supply chain. This is where blockchain plays the most crucial role by:
- Tagging items or batches at their origin
- Attaching metadata, like where, when, and how they are produced
- Updating information with every move
The result—a verifiable chain of custody—gets created. In case of any defect, fraud, or contamination, tracing back to where things went wrong becomes easier.
Quality Control & Safety
Be it pharmaceuticals, food, or luxury goods, every industry should ensure that its line of products is:
- Safe to use or consume
- Meet quality standards
- Aren’t adulterated
Blockchain offers a digital, immutable ledger to store information about conditions, like time in transit or temperature. To top it off, rest results, metadata, and other important QA datasets can be recorded on this ledger. Once stored, no one will be allowed to alter or manipulate the records. With this, businesses can perform faster recalls and offer better customer assurance.
Smart Contracts for Automation
Legacy supply chain operations still rely on manual verifications. It can be payment terms, receipt of goods, or completion of delivery. Only when these are verified can the actions be taken further. Smart contracts, deployed on the blockchain network, bring the goodness of automation.
These embed logic in the form of code. Actions will be triggered once the logic is satisfied. For example, a penalty or compensation will be issued automatically for delayed shipping. Similarly, goods scanned at the destination will trigger automatic payments.
Inventory & Logistics Optimization
Blockchain’s shared data can be easily combined with a real-time shipment tracking module. With this, businesses will gain an upper hand by:
- Gaining more visibility into goods’ locations
- The conditions they are in during transit and storage
- Seamless planning and execution
With more transparency in inventory, numerous problems can be addressed at once. Here’s how!
- Overstocking will be reduced
- Stockouts can be prevented
- Delivery routes can be optimized
- Forecasting will improve
Supply Chain Finance
Lenders and financiers can leverage verified, trusted blockchain records to assess risks accurately. This will benefit SMEs the most, especially those with a strong credit history but still in the downstream along the supply chain. They can provide accurate reports of their shipments, receipts, and deliveries—all verifiable on the chain.
Hence, the risks of fraudulent information will be substantially reduced. To top it off, they won’t have to depend on paperwork any longer, with everything being shared digitally.
Sustainable, Ethical Sourcing
Legacy systems do not provide any transparency in practices, like supply chain pollution and mining labor. However, with blockchain in supply chain, companies can trace whether sourcing is certified, sustainable, and ethically done. This makes ESG and carbon accounting hassle-free and more accurate.
Regulatory Compliance, Auditing, and Certification
With blockchain in supply chain, generating audit trails becomes much easier. In other words, businesses can extract reports on who did what, under what conditions, and when. With these records in hand, adhering to the regulatory standards won’t be an issue. Information like the origin of raw materials, environmental standards, and food safety can be presented as immutable evidence.
Benefits of Blockchain Integration with the Supply Chain
Transparency and Trust
Every involved party in the supply chain will have access to the same immutable records. Hence, there will be minimal to no room for ambiguity or misinterpretation. To top it off, it ensures accountability amongst all stakeholders on board.
Traceability and Recall Efficiency
Once a defective or non-compliant product is detected, blockchain records can verify its origin. Besides, one can pull ledger data to check the hands it has changed before it arrived at the final checkpoint. Recalling the batch will then become easier and more efficient.
Cost Savings & Efficiency Gains
Smart contracts can help automate supply chain operations. Intermediaries will be eliminated from the picture, thanks to the on-chain verification process. Furthermore, paperwork dependency can be cut out of the picture. Given these, businesses can make the supply chain more cost-effective and productive.
Enhanced Security
Right at its core, blockchain makes data immutable once it gets added to the ledger. Additionally, cryptographic hashes are used to protect the authenticity. Consensus protocols have been put in place for governance.
Improved Collaboration
With shared, trusted data, disputes amongst the stakeholders can be reduced significantly. Every participant will access the same unified ledger. Collaboration on scheduling, prompt issue resolution, and conflict management will also become easier with blockchain in supply chain.
Regulatory Compliance & Audit-Readiness
With immutable on-chain logs, audit tasks will become simpler. Every stakeholder can then seamlessly access inspection reports and certifications. Furthermore, smart contracts will enable permissionless agreements for better compliance readiness.
Challenges & Considerations for Blockchain in Supply Chain
Data Quality and Input Trustworthiness
Blockchain cannot guarantee whether the entered data is correct, accurate, or on time. If by any chance the sensor data is faulty, it can’t be corrected once added to the ledger.
Interoperability & Standardization
Currently, there is no universal roadmap for blockchain platforms to be used or the data format to be relied upon. This level of ambiguity will add discrepancies across the supply chain ecosystem.
Scalability & Performance
Primary blockchain layers aren’t meant to execute transactions at lightning-fast speed during network congestion. Hence, businesses will have to invest in scalable Layer 2 solutions for off-chain execution.
Additional Overheads and Change Management
Staff training and rollout of modifications to the legacy systems will require significant investments up front. IoT and sensors need to be acquired and then integrated with the blockchain. To top it off, smart contract integration and network setup will also incur heavy expenses.
Governance & Trust in Participants
Although smart contracts enable permissionless agreements, governance needs to be established. Hence, businesses need to put in place appropriate protocols and policies about authority, conflict handling, and trust management.
Conclusion
There’s no doubt that blockchain in the supply chain will unlock a host of new opportunities for businesses. From making data audit-ready to automating operations through smart contracts, legacy operations and roadblocks can be eliminated. However, one also needs to address the concerns that come with this technology. Standardized protocols should be implemented for the use of the blockchain platform and the data structures to be followed.
Smart contracts should be designed with extra caution and tested thoroughly. It can help tackle the issue of wrong data being added immutably to the ledger. So, if you are looking forward to harnessing the best of this technology for your supply chain business, Web 3.0 India is your one-stop destination.
