#What is a Digital Product Passport?

A Digital Product Passport (DPP) is a digital record that travels with a product through its lifecycle. It contains supply chain data, certifications, and sustainability claims that anyone can verify, from business partners to consumers scanning a QR code.

#Do I need blockchain knowledge to use Universal Goods?

No. You use a standard web dashboard and REST API. The blockchain operates invisibly behind the scenes — you never need to manage it directly. The technology is there for verification guarantees, not for you to interact with.

#What blockchain does Universal Goods run on?

Universal Goods runs on LUKSO by default — a blockchain built for digital identity and creative industries. The platform is chain-agnostic, so additional networks can be added. Your organisation gets a Universal Profile: a smart contract-based identity with richer features than a standard account.

#How do consumers verify a product?

Consumers scan a QR code or NFC tag on the product — a process called Scan-to-Sign. This opens a public page showing the product passport: where it was made, certifications, materials, and claims. The platform checks the blockchain to confirm nobody has tampered with the data.

#What does "finalising a batch" mean?

Finalising a batch freezes the item list and records a point-in-time snapshot of the current data on the blockchain. After finalising, no items can be added or removed. Batch and product data can still be updated, and the integrity anchor can be refreshed with updated data. Each anchor creates a verifiable record of the data at that moment. You can still create new batches for the same product.

#Can I update a passport after sharing it?

You can update product and batch data at any time. After updating, refresh the integrity anchor to record the new data state on-chain, then generate new passports. Previously shared passports remain valid as historical records referencing earlier snapshots.

#How do B2B connections work?

Connections are mutual relationships between two organisations on the platform. One sends an invitation, the other accepts. Once connected, both parties can exchange certification requests, invoices, and data requests. All messages are scoped to the connection and visible only to the two parties.

#What happens if I lose my batch keys?

The platform manages batch keys for you. As long as you have access to your account and organisation, you can retrieve keys through the dashboard. If you exported keys and lost them, contact support. Recovery depends on whether backups exist within the platform.

#Is my product data public?

By default, product data is private to your organisation. You control visibility per section: public, member, admin, or owner. Only sections you explicitly mark as public are accessible without login. The blockchain stores only verification hashes, not your actual data.

#How much does it cost?

Dashboard and API usage are covered by your platform subscription. On-chain operations (finalising batches, tokenisation) incur transaction costs. The platform handles these automatically — you do not need to manage network fees directly.

#Can I integrate Universal Goods with my existing ERP?

Yes. The REST API covers all core operations, so you can connect Universal Goods to any system that can make HTTP requests. Common integration patterns include syncing product catalogs from your ERP, pushing batch data from manufacturing systems, and pulling transaction records into your reporting tools. See the API Reference for the full endpoint list.

#What is the difference between a product, batch, and item?

These form a three-level hierarchy:

• Product: the definition of what you make (e.g., "Organic Cotton T-Shirt"). Contains attributes, categories, and data sections.
• Batch: a production run of that product (e.g., "Spring 2026 run of 500 units"). Batches can be finalised on the blockchain.
• Item: an individual unit within a batch (e.g., serial number UG-00142). Each item gets a unique identifier and can carry item-level data.

#What is Scan-to-Sign?

Scan-to-Sign is the process of scanning a product's QR code or NFC tag to authorise an action — claiming ownership, verifying authenticity, or confirming a transfer. The scan acts as a physical asset signature, proving the person has physical possession of the item. It is the core mechanism that bridges the physical product to its digital identity.
