Procurement: Securing Transactions and Streamlining Onboarding

Blockchain Secures Digital Contracts: Hitachi

Hitachi faced significant inefficiencies in managing procurement contracts with approximately 3,500 suppliers. The traditional paper-based process was slow, error-prone, and vulnerable to fraud.

To modernize operations, Hitachi deployed a paperless procurement system built on Hyperledger Fabric, a permissioned blockchain framework. This solution digitized contract workflows, enabling secure creation, signing, and tracking of agreements across stakeholders.

The results were immediate: the company could process at least one contract per supplier monthly with enhanced security and reduced administrative overhead. By eliminating manual intervention, Hitachi minimized the risk of tampering and improved audit readiness—key wins in an environment where compliance and speed are critical.

Blockchain Simplifies Supplier Data Management: Trust Your Supplier

Onboarding new suppliers is often a costly and time-intensive process. Trust Your Supplier identified a major industry pain point: fragmented data, lack of trust, and rising compliance demands tied to ESG (Environmental, Social, and Governance) standards.

The solution? A blockchain-powered platform developed in partnership with IBM. This open-source network allows suppliers to create a corporate digital passport—a verified identity stored on-chain. Third-party validators like Dun & Bradstreet (business data), EcoVadis (ESG), and RapidRatings (financial health) authenticate information before it’s recorded.

Once verified, this data can be securely shared with multiple buyers without repetition. Buyers gain instant access to trusted supplier profiles, dramatically accelerating due diligence.

Results include:

This model not only cuts costs but strengthens supply chain resilience by ensuring ethical sourcing and regulatory alignment.

Blockchain Modernizes Trade Finance: Marco Polo Network

International trade relies heavily on intermediaries like banks to issue letters of credit—processes that introduce delays, errors, and high transaction costs.

The Marco Polo Network tackled this challenge with a blockchain-based trade finance platform. By integrating with ERP systems, it enables real-time data exchange between exporters and importers. Smart contracts automate payments upon delivery confirmation, removing the need for manual documentation.

For example, when goods are scanned at a port, IoT sensors trigger a blockchain event. If conditions match the contract terms, payment is released instantly.

Benefits include:

Financial institutions also benefit from increased transparency and reduced counterparty risk—making blockchain a win-win for all parties involved.

Supply Chain: Enhancing Traceability and Compliance

Blockchain Ensures Regulatory Compliance: Renault

Automakers must comply with over 6,000 regulatory standards—from safety requirements to environmental mandates. For Renault, ensuring compliance across its extended supply chain was a massive coordination challenge.

Partnering with IBM, Renault launched the automotive industry’s first end-to-end blockchain platform for compliance management. Every component—from brake pads to batteries—is tracked on a distributed ledger, providing full traceability and a single source of truth.

This system automatically flags non-compliant parts and ensures updates are propagated across suppliers—even down to tier-two and tier-three vendors.

Outcomes:

Renault’s use of blockchain goes beyond compliance—it’s shaping its long-term ESG strategy.

Blockchain Tracks Ethical Sourcing: Ford

As demand for electric vehicles grows, so does scrutiny over raw material sourcing. Cobalt, a key battery component, has been linked to child labor and environmental degradation.

Ford partnered with IBM and RCS Global to implement a blockchain solution that traces cobalt from mine to factory. Each batch is logged with timestamps, locations, and audit records. IoT devices and supplier declarations feed into the system for real-time verification.

Consumers can now verify that their vehicle’s components come from ethical sources—boosting brand trust and meeting investor ESG expectations.

Key achievements:

Blockchain Authenticates Product Quality: Nestlé

After the 2008 melamine scandal in China—which affected over 300,000 infants—consumer trust in baby formula plummeted. When Nestlé launched its NAN A2 product in China, it needed a way to prove authenticity and quality.

The answer? A public blockchain platform developed with Techrock. Parents scan a QR code on packaging to access immutable records showing:

This level of transparency reassured skeptical consumers. As a result, Nestlé captured the largest market share in China’s infant nutrition sector—a direct outcome of blockchain-driven trust.

Insurance: Automating Claims with Smart Contracts

Blockchain Powers Instant Travel Insurance: AXA Fizzy

Flight delays frustrate travelers—and traditional claims processes make it worse. AXA addressed this with Fizzy, a parametric insurance product built on blockchain.

Using flight data oracles, the system monitors flights in real time. If a delay exceeds two hours, a smart contract triggers an automatic payout—no forms, no calls.

Benefits:

Fizzy demonstrates how blockchain can turn insurance from reactive to proactive.

Blockchain Accelerates Claims Processing: Etherisc

Etherisc, an insurtech startup, aimed to eliminate weeks-long claim cycles. Its blockchain platform automates claims using smart contracts validated by third-party data (e.g., weather reports or IoT sensors).

When a policyholder reports an event (e.g., crop failure due to drought), the system checks external databases to confirm conditions. If met, payment is executed immediately.

Results:

This model is scalable across agriculture, health, and property insurance—ushering in a new era of fair, fast coverage.

Energy: Enabling Decentralized Markets

Peer-to-Peer Energy Trading: Power Ledger & Google

Households with solar panels often sell excess energy back to utilities at low fixed rates. Power Ledger changed that by creating a blockchain-based P2P energy marketplace.

Integrated with Google Cloud Platform (GCP), the system uses:

Users trade energy directly with neighbors. Transactions are recorded on-chain, ensuring transparency and security.

Deployments span Australia, the U.S., India, and Japan—proving blockchain’s role in scaling renewable adoption.

Blockchain Balances the Grid: Tennet

TenneT manages power distribution across Germany and the Netherlands—regions with high renewable penetration. Wind energy fluctuates daily, making grid balancing complex.

In collaboration with IBM and Sonnen, Tennet used blockchain to connect home battery systems to the grid. When supply exceeds demand, excess power is stored; during peaks, batteries discharge automatically.

Blockchain ensures all transactions are transparent and verifiable. The result? Millions saved by avoiding curtailment and inefficient rerouting.

Local prosumers benefit too—reducing energy bills while supporting sustainability.

Legal: Digitizing Agreements and IP Management

Blockchain Automates Legal Contracts: OpenLaw

Legal teams waste countless hours on contract revisions and manual execution. OpenLaw introduced smart legal agreements—hybrid documents combining natural language with executable code.

Lawyers draft contracts using templates embedded with smart contract logic. Terms like payment releases or IP transfers trigger automatically when conditions are met.

Advantages:

This fusion of law and code is redefining how agreements are created and enforced.

Blockchain Secures Intellectual Property: IPwe

Patents are valuable—but hard to track and value accurately. IPwe partnered with IBM to build a cloud-based blockchain registry for intellectual property.

Patents are tokenized and stored securely, allowing investors to assess value based on transparent data. Companies can showcase innovations fairly and efficiently.

Today, IPwe’s database holds 80% of the world’s patents—making it one of the most comprehensive IP platforms globally.
