The current supply chain management (SCM) system has several fundamental problems that could be solved by blockchain applications. From inventory stockpiling to counterfeit products, blockchain applications could help to minimize these issues and save billions of dollars. Many of these applications, which were discussed in the Harvard Business Review, are summarized below. While the current SCM does not support the improvements that blockchain could make, it’s important to consider how blockchain can, and likely will, impact the future of SCM.

What Are the Current Problems With Supply Chain Networks?

  • Maintaining quality control standards for specific product SKUs (stock-keeping units)
  • Accurate lead times for manufacturing and shipping
  • Duplicate SKUs reported on shipping manifests
  • Inability to track products in real-time from Point A to Point B
  • Counterfeit products that some distributors mix with real product to repackage and ship
  • Tedious financial audits using legacy enterprise resource planning (ERP) systems
  • Improper inventory allocation which leads to confusion in purchase agreements

How Can We Use Blockchain Technology to Create a Transparent Value Chain?

Traceability

Using the blockchain ledger for supply chain transactions will make it clear who the originator for a product is and who the current owner is which will improve fraud detection for counterfeit products across international borders. This will also identify faulty products earlier in the value chain. Additionally, integrating ERP systems with blockchain networks will create a single source of truth and remove any human errors in shipping manifests.

Efficiency

With a transparent ledger, no manufacturer or distributor can simply hold inventory from customers due to convenience without prior disclosure. Additionally, a transparent supply chain will allow for improved forecasting of goods both because there will be less variability for lead times and because customers can optimize their demand forecasts to maintain a lower base stock policy.

Financial Auditing for Contracts

Smart contract languages like Solidity are incredibly beneficial for automating the terms of a contract based on execution within a ledger. There will be no confusion over how much inventory was consigned versus purchased outright. Further, it will be easier for all parties along the value chain to maintain a no-discrepancy bill of lading and general financial records for auditing various holding, transportation, and labor costs as well as incoming revenue per SKU.

These benefits are incredibly useful, especially during times like the COVID-19 pandemic where there are shortages of essential goods in many local markets. If we look at the Port of Los Angeles in the United States as an example, with a blockchain framework for supply chain, we will be able to ascertain which product SKUs are still in containers on ships, which products are on dry land at the ports, and which products have been unloaded at the local site for facilities management.
