Case Study 1: Hitachi's Procurement System Modernization

Hitachi, the Japanese multinational, faced a familiar hurdle: outdated procurement processes that couldn’t keep up with modern business needs. Their solution? A smart integration of blockchain technology to modernize their system without starting from scratch.

Challenges Faced by Hitachi

Hitachi’s procurement operations were massive, handling thousands of contracts every month. The head office alone worked with 2,000 partners, while the entire group dealt with 3,500. Their traditional paper-based system was riddled with inefficiencies. Employees spent hours on tasks like mailing and manually verifying documents, managing around 333 cases monthly before blockchain was introduced.

On top of that, version control issues and vulnerabilities to tampering created risks of fraud and potential legal problems. The shift toward remote work only made things worse, as physical document handling led to delays and increased the chance of errors.

"Procurement wanted to digitize its processes while maintaining security and trust. Blockchain provides an immutable record that provides that trust."

• Kazuyoshi Masuya, Senior Engineer, Service Delivery Division, Hitachi, Ltd.

Recognizing these challenges, Hitachi opted for a phased blockchain rollout to address the bottlenecks.

Blockchain Integration Strategy

Rather than replacing their entire system, Hitachi chose a step-by-step approach. Their Service Delivery Division developed the Electronic Signature Service (ESS) using Hyperledger Fabric, an open-source blockchain framework, to digitize contract management.

The ESS streamlined contract signing by securely recording transactions on blockchain, ensuring verification that couldn’t be altered. The main goals were clear: reduce processing time, eliminate paper-based workflows, and build trust in digital systems to support remote work. Hitachi started with a pilot program in one division before expanding the service.

Outcome and Business Impact

This approach showed how blockchain can modernize legacy systems without requiring a full overhaul. The results were immediate and measurable.

By July 2021, Hitachi’s head office procurement division began processing all new contracts digitally through the ESS. This change increased their capacity by 20%, going from 333 to 400 cases a month, all without hiring additional staff or extending work hours.

The labor savings were equally impressive. Hitachi estimated they saved roughly 1,225 person-hours per month, freeing up employees to focus on more valuable tasks instead of routine admin work.

"Hitachi's Electronic Signature Service has greatly simplified and streamlined a very time-consuming process."

• Kazuyoshi Masuya, Senior Engineer, Service Delivery Division, Hitachi, Ltd.

The blockchain-powered system didn’t just improve efficiency; it also resolved issues like document tampering and version control by maintaining an unchangeable audit trail. This ensured contracts were processed smoothly, regardless of where employees were working.

Case Study 2: Ford's Ethical Cobalt Tracking

Ford tackled a pressing issue in the electric vehicle (EV) industry: ensuring that the cobalt used in its batteries was ethically sourced. With the growing demand for EVs, transparency in supply chains has become essential for maintaining consumer trust and meeting environmental, social, and governance (ESG) standards.

Supply Chain Challenges

The cobalt supply chain is fraught with both ethical and operational challenges. As cobalt demand is projected to grow eightfold by 2026, driven by its critical role in batteries for EVs and smartphones, the need for responsible sourcing has become more urgent. Complicating matters further, over 60% of the global cobalt supply comes from the Democratic Republic of Congo (DRC), a region where mining practices have long been associated with human rights violations. In 2012, UNICEF reported that approximately 40,000 children were working in DRC mines, and at least 20% of the country's cobalt is mined by locals, including children.

Ford's traditional supply chain systems lacked the transparency needed to verify whether the cobalt it used was sourced ethically. To address this, the company needed a secure, reliable way to trace materials from the mines to its manufacturing plants while adhering to international ethical and environmental standards. This challenge led Ford to adopt blockchain technology, complemented by IoT integration.

Blockchain and IoT Integration

Ford collaborated with IBM, Huayou Cobalt, LG Chem, and RCS Global to implement a blockchain-based solution for tracking cobalt throughout its supply chain. The pilot program traced cobalt from Huayou's mine in the DRC through processing facilities in South Korea and finally to a Ford plant in the United States. Blockchain technology created an unchangeable digital record at each stage of the supply chain, ensuring that the material's journey complied with OECD ethical guidelines.

This system not only modernized Ford's supply chain but also integrated seamlessly with its existing infrastructure. By combining IoT data with blockchain, Ford was able to digitize its supply chain, making it both transparent and accountable.

"We remain committed to transparency across our global supply chain. By collaborating with other leading industries in this network, our intent is to use state-of-the-art technology to ensure materials produced for our vehicles will help meet our commitment to protecting human rights and the environment."

• Lisa Drake, vice president of global purchasing and powertrain operations for Ford Motor Company

Results and Improvements

The blockchain system provided an immutable audit trail that verified the ethical sourcing of cobalt, significantly enhancing accountability and consumer confidence. By offering a verified sourcing trail, Ford reinforced trust in the sustainability of its EVs. Additionally, the system reduced the risk of engaging with suppliers involved in unethical practices by flagging non-compliant materials before they entered the supply chain.

"With the growing demand for cobalt, this group has come together with clear objectives to illustrate how blockchain can be used for greater assurance around social and environmental sustainability in the mining supply chain."

• Manish Chawla, general manager of the global industrial products industry for IBM

Ford's pilot program showed how blockchain can revolutionize supply chain transparency, particularly in industries where ethical sourcing is paramount. By integrating IoT data with blockchain records, Ford created a system capable of not just tracking materials but also ensuring that every participant in the supply chain adhered to established ethical standards. This initiative highlights how technology can modernize and bring accountability to even the most complex supply chains.

Case Study 3: Walmart's Food Traceability Network

Walmart, the largest retailer in the world, tackled food safety challenges head-on by adopting blockchain technology to track products from farms to store shelves. This move addressed long-standing supply chain inefficiencies and delivered measurable improvements. Let’s dive into how Walmart achieved this transformation.

Food Safety Challenges

Before blockchain, Walmart relied on manual tracking systems that were painfully slow. For instance, tracing the origin of sliced mangoes took a staggering 6 days, 18 hours, and 26 minutes. Such delays posed significant risks during foodborne illness outbreaks, which happened at least 18 times in the United States in 2018 alone. In these situations, retailers often discarded entire categories of produce, leading to enormous waste and financial losses for farmers.

Frank Yiannas, Walmart's former Vice President of Food Safety, described the complexity of the issue:

"People talk about the food supply chain, but it is not actually a chain, it's a complex network."

The challenges weren’t limited to speed. In international markets like China, Walmart struggled with verifying the authenticity of products - especially pork - due to weak documentation and trust issues. The need for a faster, more transparent, and reliable system was clear.

Blockchain Implementation Process

In 2016, Walmart teamed up with IBM to develop a food traceability system using Hyperledger Fabric blockchain technology. The initiative began with two pilot projects: one focused on tracking mangoes in U.S. stores, and the other on tracing pork in China.

To ensure consistency, Walmart collaborated with suppliers to define key data points using GS1 standards. Suppliers could easily input tracking information through a web-based interface. Karl Bedwell, Senior Director at Walmart Technology, explained the significance of this effort:

"Creating a (traceability) system for the entire food supply ecosystem has been a challenge for years, and no one had figured it out. We thought that blockchain technology might be a good fit for this problem, because of its focus on trust, immutability, and transparency."

Walmart took a collaborative approach, involving suppliers and even competitors to ensure the platform benefited the entire food ecosystem. Frank Yiannas emphasized this spirit of partnership:

"This is not about competition, this is about collaboration. It's about creating a solution that offers shared value for stakeholders."

After successful pilot tests, Walmart expanded the system, tracking over 25 products from five suppliers. Eventually, the company required all suppliers of fresh leafy greens to adopt the blockchain system for traceability. This broad rollout marked a major step forward in supply chain modernization.

Key Outcomes

The results were game-changing. Tracing the origin of products went from taking days to just 2.2 seconds. Walmart reported a 50% reduction in the time needed to trace food origins, while IBM noted that the Food Trust platform cut recall times by up to 80%. These improvements enabled Walmart to quickly identify contaminated products, minimizing food waste and protecting both consumers and safe suppliers.

Frank Yiannas reflected on the impact of blockchain technology:

"I really had an 'aha' moment once I deeply understood the technology. I had been hesitant about creating yet another traceability system – the ones we had tried in the past never scaled. Now I understand that was because they were centralized databases. Blockchain, with its decentralized, shared ledger felt like it was made for the food system!"

Yiannas also highlighted the system's efficiency:

"This solution allows us to see the whole chain in seconds! We can take a jar of baby food and see where it was manufactured and trace back all the ingredients to the farms!"

The blockchain’s unchangeable records boosted trust among suppliers and customers, while the shared platform enhanced data security and interoperability across the network.

Walmart’s experience shows how blockchain can revolutionize outdated systems, offering a practical roadmap for other organizations aiming to integrate cutting-edge technology into their operations.

Case Study 4: Nestlé's Infant Formula Authentication

Nestlé's use of blockchain technology to address a trust crisis in its infant formula products highlights how modern tech can help restore consumer confidence after major safety concerns.

Challenges in Consumer Trust

Nestlé faced a deeply personal challenge in the infant nutrition sector, especially in the wake of the 2008 Chinese milk scandal. This tragedy, involving contaminated milk products, caused fatalities and led to import bans in at least 11 countries. Hundreds of thousands of infants were affected, shaking consumer trust in infant nutrition products worldwide. For Nestlé, the crisis hit particularly hard in Asian markets, where the company held a strong presence.

But the challenges didn’t stop there. Nestlé also faced backlash from Greenpeace over its association with Sinar Mas, a palm oil supplier accused of deforestation and destroying habitats in Southeast Asia. A viral campaign compared eating Kit Kat bars to harming orangutans, further damaging the brand's reputation. Additionally, the company was criticized for aggressively marketing infant formula in developing nations, often undermining breastfeeding practices among vulnerable populations.

These controversies, combined with growing consumer demands for transparency, posed a serious threat to Nestlé’s market position. According to the World Health Organization, unsafe food causes 600 million cases of foodborne illnesses and 420,000 deaths annually. Parents wanted more than just assurances - they demanded proof of product safety and sourcing. Traditional tracking systems simply couldn’t offer the level of trust required for something as crucial as infant nutrition.

Benjamin Dubois, Blockchain Lead and Digital Transformation Manager at Nestlé, summed up the technological hurdle:

"We have looked at other legacy technologies to do the same thing…the problem we had is that there is no technology that was flexible enough, that had the level of trust and immutability of the blockchain."

Blockchain and Mobile Integration

Nestlé partnered with Techrock to create a blockchain-based platform specifically for its NAN A2 infant formula in China. This wasn’t just about adopting new technology - it was about rebuilding trust with parents who had lost confidence in infant nutrition products.

Through this blockchain solution, parents could instantly verify product details - like ingredients, origin, and packaging - using their smartphones. This level of transparency went far beyond traditional product labels, offering a complete view of the supply chain.

Chris Tyas, Nestlé's Global Head of Supply Chain, emphasized the importance of trust:

"People want to know, quite rightly, where ingredients they give to their baby have come from. We wanted a product in which trust meant something."

This initiative wasn’t limited to infant formula. Nestlé later expanded blockchain transparency to other products. For example, in April, the company introduced blockchain data access for Mousline purée in France. By integrating blockchain with mobile technology, Nestlé set a new standard for transparency, helping to rebuild consumer confidence and regain market share.

Business Impact

The blockchain initiative reshaped Nestlé’s position in one of its toughest markets. With improved transparency, the company regained consumer trust and secured a leading market share in China's infant nutrition sector. This was no small feat in a market where trust had been severely damaged.

Magdi Batato, Executive Vice President and Head of Operations at Nestlé S.A., highlighted the company’s commitment to informed consumer choices:

"We want our consumers to make an informed decision on their choice of products – to choose products produced responsibly. Open blockchain technology might allow us to share reliable information with consumers in an accessible way."

The blockchain system provided a level of transparency that older methods couldn’t match. Benjamin Ware, Global Head of Responsible Sourcing at Nestlé S.A., emphasized its broader impact:

"This open blockchain technology will allow anyone, anywhere in the world to assess our responsible sourcing facts and figures. We believe it is another important step towards the full disclosure of our supply chains announced by Nestlé in February this year, raising the bar for transparency and responsible production globally."

Nestlé’s blockchain journey, which began with pilot programs in 2017, proved how technology could help rebuild trust after a crisis. By committing to full supply chain transparency, Nestlé showed that blockchain isn’t just a tech solution - it’s a strategic tool for restoring consumer confidence in a time when trust is a critical competitive edge. The successful integration of blockchain with existing systems highlights its potential to transform industries far beyond food production.

Case Study 5: Trust Your Supplier Consortium

The Trust Your Supplier (TYS) consortium highlights how blockchain technology is reshaping supplier onboarding processes. This initiative stands out as one of the most ambitious efforts to modernize enterprise procurement systems.

Challenges in Supplier Onboarding

Before blockchain entered the scene, onboarding suppliers was a tedious process. Suppliers had to repeatedly share the same information with multiple buyers, leading to delays and inefficiencies. Gary Storr, General Manager of Trust Your Supplier, described the situation:

"Onboarding new vendors is painstaking, and heightened privacy and compliance requirements have exacerbated the delays."

A survey of 100 large enterprises revealed that supplier approvals often took 45 to 60 days, with IBM averaging 30 days before adopting blockchain technology. David Post, Managing Director of IBM Blockchain, captured the widespread frustration:

"This is a pain point across all companies and all industries."

The Institute for Supply Management noted that risk assessments could stretch the process to six months. Additionally, keeping supplier information up to date was a constant challenge, as manual methods couldn’t keep up with changes like relocations, mergers, or reorganizations.

Blockchain-Powered Digital Passports

In 2019, IBM partnered with Chainyard to launch Trust Your Supplier, a blockchain network built on Hyperledger Fabric aimed at streamlining supplier information management. A key innovation was the introduction of digital passports. Each supplier received a unique decentralized identifier (DID) and a digital passport stored on the blockchain. This passport included non-sensitive details about management, finances, and contacts, while critical data remained encrypted and off-chain.

The system operates through three channels: one for supplier data, another for decentralized identifiers and verifiable credentials, and a third for audit trails of external interactions. Bob Murphy, Chief Procurement Officer at IBM, highlighted the platform’s impact:

"This platform will make life simpler for both suppliers and buyers, and create significant savings for chief procurement officers."

To ensure credibility, the network integrates third-party verifiers like Dun & Bradstreet, EcoVadis, and RapidRatings. Gary Storr explained its broad appeal:

"Trust Your Supplier is for big organizations, small organizations, any business anywhere in the world. We don't have a lot of constraints."

This comprehensive framework paved the way for significant improvements in efficiency.

Results and Efficiency Gains

The results were game-changing. Blockchain reduced onboarding times from 60 days to just 3 days - a 95% improvement. IBM, specifically, cut its process from 30 days to 3 or 4 days. Buyers also saw significant cost savings, with a 50% reduction in the expense of verifying and maintaining supplier information. On average, organizations saved nearly $500 per supplier. For suppliers, faster onboarding meant quicker revenue generation, as they could start selling sooner.

The consortium’s reach grew rapidly, encompassing 25 major corporate members and hundreds of thousands of suppliers. David Post praised the progress:

"We've made more progress in 18 months than any other network I can think of. The winning model for a blockchain network is small and nimble paired with large and trusted."

This case study underscores how blockchain can replace fragmented, manual processes with a unified, transparent system, delivering tangible business benefits while integrating seamlessly into existing enterprise workflows.

Common Challenges in Blockchain-Legacy System Integration

While the success stories in blockchain adoption are encouraging, they also reveal some recurring hurdles when integrating blockchain with legacy systems. A significant 70% of organizations struggle with this process due to mismatched data formats, outdated infrastructure, and limited interoperability. These challenges highlight why a well-thought-out, phased approach is essential.

Data Compatibility Issues

One of the biggest headaches is converting data from traditional formats into blockchain-compatible structures. Legacy systems often rely on formats like CSV or relational databases, which don’t align well with blockchain’s JSON-based frameworks.

To make matters worse, poor data quality in legacy systems can undermine the integrity of blockchain networks. This makes thorough data audits a must. These audits can help identify inconsistencies, duplicates, or corrupted records before migration.

Middleware plays a crucial role here. It not only ensures sensitive data remains protected but also helps meet data residency requirements:

"Middleware ensures that sensitive customer and financial information is never needlessly exposed on-chain, and complies with relevant data residency regulations."

Another vital step is standardizing data models. Companies must carefully convert existing records into blockchain-ready formats without disrupting upstream data sources.

Performance and Scalability

Performance is another stumbling block. Legacy systems are designed to handle thousands of transactions per second, but blockchain networks often lag behind, creating bottlenecks.

The challenge becomes even tougher when large datasets or real-time synchronization are involved. Many legacy systems lack the flexibility or scalability needed for smooth blockchain integration.

A notable example is the Marco Polo Network. They tackled performance issues by integrating blockchain directly with supply chain ERP systems. This enabled automated settlement processes that improved working capital cycles while maintaining transaction speed. Their approach shows how strategic integration points can help reduce performance-related setbacks.

However, such integration is resource-intensive. It requires careful planning, specialized expertise, and significant investment to manage large transaction volumes without sacrificing speed or efficiency.

Key Management and Security

Legacy systems also fall short when it comes to managing cryptographic keys. While traditional systems rely on centralized authentication, blockchain demands distributed key management across multiple nodes and participants.

Smart contract vulnerabilities further complicate matters, as coding errors can lead to unexpected behaviors or even financial losses. Additionally, governance within blockchain networks presents its own challenges. Decentralized systems often struggle to respond to emerging threats or implement updates, especially in consortium blockchains where multiple organizations are involved. The Trust Your Supplier network is a prime example of how governance can become a sticking point.

Interoperability is another major issue. Standards for data formats, APIs, and communication protocols vary widely across blockchain platforms and legacy systems. This forces organizations to create custom solutions for each integration point, adding to the complexity and ongoing maintenance needs.

Best Practices for Blockchain Integration

The case studies highlight three strategies that can greatly enhance the success of blockchain integration. These approaches draw from real-world examples, offering a roadmap for modernizing legacy systems while avoiding common challenges and fully leveraging blockchain's potential.

Phased Rollout Strategies

A phased rollout approach helps mitigate risks when integrating blockchain with existing systems. Walmart's food traceability project is a prime example. They implemented a two-phase plan, starting with leafy greens suppliers. The first phase required suppliers to establish one-step traceability by January, followed by testing the Food Trust network with various products before expanding to a full rollout. This method led to remarkable results, cutting trace times from days to mere seconds. Similarly, Walmart Canada adopted a phased approach, reducing invoice dispute rates from 70% to less than 1%.

As John Kent, director of the University of Arkansas' Supply Chain Research Center, emphasized:

"Without willing participants in the supply chain, this initiative will not work."

To succeed, businesses should build consensus on operational rules early and involve both large and smaller suppliers to ensure adoption across varied infrastructure capabilities.

Hybrid System Architectures

Rather than replacing legacy systems outright, organizations can adopt hybrid architectures that allow blockchain to complement existing infrastructure. This approach leverages the strengths of current systems while introducing blockchain's capabilities. Hybrid blockchains - offering a mix of public and private features - enable selective transparency and efficient operations.

For instance, XinFin and Ramco Systems developed a hybrid network for supply chain logistics by integrating Quorum with Ethereum. This setup combined the speed of private blockchains with the validation power of public blockchains. Power Ledger's migration to Google Cloud Platform is another example, enabling its energy trading platform to scale across multiple countries. Additionally, using off-chain storage and computation can significantly ease the processing load on blockchain networks.

Consortium-Based Collaboration

Industry consortiums provide a collaborative way to overcome individual limitations and establish shared standards. For example, the Trust Your Supplier consortium partnered with IBM to create an open-source blockchain platform for secure data sharing. This initiative reduced supplier onboarding time by over 70% and cut data verification costs by 50%. The platform also enabled trusted third-party verifiers, such as Dun & Bradstreet and EcoVadis, to validate supplier data and international certifications almost instantly.

Consortiums are instrumental in setting common protocols and data formats, which improve interoperability between blockchain systems. They also help educate stakeholders about blockchain's advantages and establish governance frameworks that build trust and transparency. By working with regulatory bodies, consortiums assist organizations in meeting compliance requirements. Pooling resources within a consortium allows companies to share the costs and risks of blockchain development, making it a practical step toward modernizing legacy systems and advancing blockchain adoption.
