Introduction
Digital Product Passports (DPPs) are quickly becoming one of the most talked-about innovations in the circular economy, sustainability, and supply chain transparency. The European Union is rolling out regulations that will require many product categories – batteries, textiles, electronics, construction materials, and others – to maintain a digital trail of their origin, materials, environmental impact, and repairability. At first glance, blockchain seems like the perfect foundation for this system. After all, it offers immutability, decentralization, and traceability – three qualities often highlighted as essential for trustworthy product data.
Definition
A Digital Product Passport (DPP) is a structured digital record that contains key information about a product’s materials, components, manufacturing processes, environmental impact, and instructions for repair, reuse, or recycling. It is designed to improve transparency throughout the product’s lifecycle, enabling businesses, regulators, and consumers to make informed decisions and supporting a more circular, sustainable economy.
What Are Digital Product Passports and Why Do They Matter?
A Digital Product Passport is a structured digital record that accompanies a product throughout its life. Think of it as a detailed, evolving identity card. A typical DPP might include:
- Material composition
- Manufacturing locations
- Carbon footprint and environmental impact data
- Guidance for repair, reuse, and recycling
- Ownership or custody transitions
- Compliance evidence
- Serial numbers and product IDs
- End-of-life handling instructions
The goal is to make supply chains more transparent and products more circular. When recyclers know what is inside a battery pack, they can recover valuable materials more efficiently. When consumers can scan a QR code to access repair instructions, products last longer. When regulators can verify sustainability claims, environmental policies become enforceable.
Critically, none of these goals require blockchain. A well-designed database could store this information just as effectively.
Why Blockchain Became the Default Answer
Blockchain entered the DPP conversation not because it was the only option, but because it offered appealing characteristics at a moment of trust crisis in global supply chains.
Immutability:
Once data is added to a blockchain, it cannot be altered without leaving a trace. For industries plagued by fraud—counterfeit goods, greenwashing, false sustainability claims—this looked like a cure-all.
Decentralization:
In multi-stakeholder ecosystems, no one wants a competitor or regulator controlling the central database. Distributed ledgers avoid a single “owner” of truth.
Traceability:
Blockchains naturally record timestamped events in sequence. For products moving across many countries and companies, this provides a verifiable trail of custody.
Cryptographic Trust
Data can be signed and verified without trusting the entity that stores it.
Given these capabilities, early DPP pilots – especially in batteries, textiles, and luxury goods – embraced blockchain enthusiastically.
But as real-world implementations progressed, organizations discovered limitations that challenged the assumption that blockchain was the best foundation.
What Blockchain Doesn’t Solve
The biggest misconception about blockchain in DPPs is that it somehow guarantees data quality. It does not.
1. Garbage In, Garbage Forever
If a manufacturer enters false environmental data, the blockchain will faithfully store that lie forever. Immutability protects data from tampering, not from being inaccurate in the first place. Verification still requires audits, certifications, and enforcement—off-chain processes.
2. Most Product Data Doesn’t Need to Be Immutable
Repair instructions, firmware updates, disassembly guides, and recycling notes must be editable as knowledge evolves. Immutability can actually hinder usability.
3. Cost and Complexity Increase Quickly
Running nodes, validating transactions, integrating with ERP systems, and training partners is expensive and time-consuming. Many small suppliers simply cannot participate in blockchain ecosystems without technical support.
4. Performance Bottlenecks
High-volume product environments—such as textiles with millions of SKUs—often exceed blockchain’s practical throughput unless you rely heavily on off-chain storage (which undermines the whole idea).
5. Interoperability Remains Messy
Numerous blockchain platforms exist, each with its own standards. Cross-chain compatibility is theoretically possible but rarely implemented seamlessly.
Blockchain is powerful, but it is not free and not frictionless.
When a Traditional Database Works Just Fine
Most DPP requirements can be fulfilled by conventional technologies, sometimes far more efficiently:
Centralized or Federated Databases:
Large organizations that already run complex digital infrastructure—OEMs, logistics firms, retailers—can store passport data in existing systems. Access can be granted via APIs with permissions and audit logs.
Cloud-based distributed systems:
Platforms such as AWS, Azure, or Google Cloud support versioning, redundancy, access controls, and cryptographic signing without blockchain overhead.
GS1 and standardized identifiers:
Product passports rely on standardized IDs like UPC, EPCIS, and GTIN much more than they rely on blockchain.
Verifiable Credentials (VCs) Without Blockchain
W3C Verifiable Credentials and Decentralized Identifiers (DIDs) can be implemented with or without blockchain. Many organizations are adopting non-blockchain DID methods.
Secure centralized registries
For compliance-heavy sectors (like batteries), regulators are often more comfortable with centralized systems that they can audit directly.
For the majority of products, blockchain adds more complexity than value.
So, When Does Blockchain Make Sense for Product Passports?
While blockchain isn’t universally necessary, there are scenarios where it shines.
High-Risk, High-Value Products:
Pharmaceuticals, aircraft components, luxury goods, and lithium-ion batteries have higher risks of fraud or safety issues. Immutable records can support regulatory compliance and recall management.
Supply Chains with Many Competitors:
If multiple parties do not trust any single entity to host the database, a permissioned blockchain can serve as a neutral infrastructure.
Multi-country regulatory environments:
Products moving across jurisdictions with different reporting structures benefit from a decentralized trust model.
When tokenization or incentives matter:
If the passport needs to support circular economy incentives—such as recycling credits, carbon tokens, or material tracking via tokenized assets—blockchain provides the structure.
Long product lifecycles:
Industrial machines, vehicles, and infrastructure assets may outlive the original manufacturers. A blockchain ensures that records persist beyond a company’s lifespan.
In these contexts, blockchain can genuinely improve data integrity and trust.
Choosing the Right Tool for the Job
The key insight is this:
Digital Product Passports are not a blockchain problem. They are a data architecture problem.
Blockchain can be part of the solution, but it is not the only solution and often not the simplest or most cost-effective one.
A practical approach is:
- Start with the regulatory requirements.
Determine what data must be stored, for how long, and who needs access. - Consider the trust model.
If parties trust each other or a central authority, blockchain is likely unnecessary. - Evaluate the need for immutability.
Only a subset of DPP data benefits from permanent, tamper-evident storage. - Assess the ecosystem’s technical maturity.
Blockchain networks require collaboration and technical investment. - Avoid blockchain as a default.
Instead, apply it only where it clearly solves a problem other tools cannot.

Conclusion
Digital Product Passports represent a major shift toward transparency and sustainability in global commerce. Blockchain is an appealing, sometimes powerful tool – but not a universal requirement. For many organizations, traditional databases, cloud infrastructure, and standardized identifiers will meet DPP expectations with far less cost and friction.
