Ensure the authenticity of your data with verifiable credentials
Secure, transparent and auditable digital trust across your value chain
The CircularPass Verifiable Credentials module allows you to digitally issue, sign, and validate key information about products, processes, or actors in the value chain.
Thanks to its interoperability and optional blockchain anchoring, credentials can be shared and verified in a secure, transparent, and auditable manner.
About
What are verifiable credentials?
Verifiable Credentials are digital certificates that prove that information is authentic, complete, and issued by a trusted source. They function like the digital version of a signed document, but with a fundamental difference: the information is stored structured within the credential itself, in a standardized format that can be read and verified by any compatible system.
Each credential contains essential data about the product, process, or entity, along with the identity of the issuer and a cryptographic signature that guarantees its authenticity. Thus, the content is not stored as a simple attachment, but as a verifiable, portable, and interoperable digital object, aligned with the W3C Verifiable Credentials standard.
Optionally, the credential's digital fingerprint (hash) can be anchored in the blockchain, strengthening its traceability and ensuring that the information has not been altered.

How it works
How do verifiable credentials work?
Verifiable Credentials work based on a simple yet powerful model, defined by the W3C international standard.
It involves three main actors: issuer, holder, and verifier.
Issuer creates and signs the credential
The issuer creates a digital credential containing structured data about a product, process, or entity. The credential is cryptographically signed to guarantee its authenticity and integrity, and its digital fingerprint can optionally be anchored to the blockchain.
Holder stores and shares the credential
The holder securely stores the credential and decides when and with whom to share it. This makes it possible to prove the veracity of product, process, or organisational data while keeping control over how the information is exchanged.
Verifier validates authenticity instantly
The verifier checks the credential's cryptographic signature and authenticity instantly, without having to contact the issuer. This enables secure, transparent, and interoperable verification across different systems and organisations.
