Walmart Canada Employing Blockchain-  Overcoming Pressing Challenges For Supply Chain Management

For many years, the transportation industry has grappled with substantial inconsistencies in the invoicing and payment process for freight carriers. These discrepancies have resulted in protracted payment delays and costly reconciliations, presenting a significant challenge to the industry. As a renowned leader in supply chain management, Walmart has taken an innovative approach to resolve this issue. Utilizing blockchain technology, Walmart has developed an automated system that seamlessly handles invoices and payments for its 70 third-party freight carriers. This revolutionary solution harnesses the power of blockchain to address long-standing issues and streamline supply chain operations. In this blog, we delve into the fascinating journey of how Walmart, a globally recognized retail giant, effectively utilized blockchain technology to address and overcome long-standing obstacles in supply chain management. We'll take a closer look at the pressing issues that were inherent in their supply chain process, and how the unique properties of blockchain technology were harnessed to provide a ground-breaking solution.

Understanding the Challenge and the Blockchain Proposition

Tasked with managing over 500,000 annual shipments across Canada, Walmart found itself amid a significant data management challenge. A plethora of data points, ranging from stop locations to fuel consumption and temperature updates, needed to be meticulously monitored and incorporated into every invoice. This process, involving more than 200 unique data points, naturally led to numerous discrepancies. As a result, a staggering 70% of invoices required labor-intensive reconciliation. Recognizing the underlying problem of incompatible information systems, a tech leader at Walmart Canada proposed the implementation of blockchain technology. Renowned for its decentralized, transparent, and immutable properties, blockchain technology represented a potential solution for unifying the process and establishing a universal source of truth, thus eliminating the inconsistencies plaguing the system. Accentuate your retail ecosystem by building smart solutions with Blockchain.

Collaborating with DLT Labs and Launching the Blockchain Network

In pursuit of this innovative solution, Walmart Canada collaborated with DLT Labs, a company globally recognized for its role in developing and deploying enterprise-grade blockchain solutions. This joint venture, also involving Bison Transport, one of Walmart Canada's freight carriers, led to the development of a blockchain network specifically designed to streamline the invoice and payment process. This pilot project, named DL Freight, was successfully launched in January 2019. Upon exhaustive testing and subsequent refinement, it was extended to 69 other carriers by March 2021. DL Freight continually gathers and synchronizes data throughout the delivery process, accessible exclusively to the relevant parties. This ensures a high level of transparency and security in the data handling process.

The successful deployment of the DL Freight blockchain has yielded significant advantages, heralding a new era in supply chain management for Walmart Canada. Before the blockchain intervention, data discrepancies resulted in a staggering 70% of invoices being disputed. The introduction of the blockchain system brought about a transformative change, reducing this rate to less than 1%. This marked decrease in disputes has led to the prompt payment of carriers, resulting in a notable surge in carrier satisfaction levels. But the merits of the DL Freight blockchain extend beyond merely resolving disputes. One of its standout features is its ability to perform real-time calculations and updates of costs. As the delivery process progresses, the system automatically accounts for accruing costs, crafting a dynamic invoice that evolves concurrently. The visibility and transparency into financial operations this feature provides are unprecedented in the industry. In essence, the blockchain solution has not only remedied the long-standing issue of data discrepancies but has also ushered in a new standard of financial transparency. This has resulted in a highly efficient supply chain operation, fostering trust and satisfaction among the carriers, and making Walmart Canada's blockchain solution a success story worthy of emulation.

Learning Lessons and Looking Ahead- Gearing Up For Future

The successful implementation of Walmart Canada's DL Freight blockchain offers a wealth of insights for businesses contemplating the deployment of similar blockchain solutions. A vital lesson learned is the necessity of inclusive stakeholder participation during the design and development phase. Understanding the unique perspectives and requirements of all parties ensures the crafted solution benefits everyone involved. Another key consideration is the choice between a public and private blockchain. It's crucial to weigh the pros and cons of each, considering factors like business privacy, data security, and the level of control required over the data. Consensus on business rules and calculations forms another cornerstone of the process. The blockchain network should incorporate agreed-upon metrics and formulas, ensuring that all stakeholders are on the same page regarding the network's operation. Moreover, it's crucial to integrate checks and balances into the blockchain system to prevent errors, enhance performance, and create a self-learning system. Instead of replacing legacy IT systems entirely, blockchain can be designed to coexist and synergize with these systems, leveraging their unique strengths and stored data. Beyond dispute resolution and data reconciliation, Walmart Canada's blockchain solution has opened doors for substantial operational improvements. The ability to optimize routes, vehicle loads, travel times, and to provide real-time updates on expected truck arrivals has significantly enhanced delivery coordination. This successful case illustrates the immense potential of blockchain for supply chain optimization and presages a bright future for the technology in logistics management.


Walmart Canada's strategic adoption of blockchain technology exemplifies a pioneering approach to overcoming conventional supply chain challenges. The implementation of the DL Freight blockchain system has proven successful in managing complex logistics data, enhancing transparency, reducing invoice disputes, and improving carrier satisfaction. This new level of accuracy and reliability in data management has not only streamlined operations but also led to significant operational enhancements. It has allowed for real-time cost calculation, optimization of routes, and efficient delivery coordination, thereby elevating the overall efficiency of Walmart Canada's supply chain. Beyond merely serving as a resolution to data discrepancies, this initiative illustrates the transformative potential of blockchain technology. The case of Walmart Canada serves as a compelling blueprint for other companies navigating similar supply chain complexities. It demonstrates how, with thoughtful application, blockchain can foster an environment of trust, efficiency, and enhanced operational performance. As we look forward, Walmart Canada's success story underpins the transformative role that blockchain technology can play in the future of supply chain management, offering valuable insights and lessons for businesses worldwide.
