Descentralized Identity and
Self-Managed Verifiable Credentials


Own your identity

With VIDchain, we offer secure identity solutions that guarantee people's privacy, rights, and freedoms and promote a more digital and sustainable world.  

VIDchain provides a unified, interoperable, and tamper-proof infrastructure with crucial benefits for businesses, users, and IoT management systems.  

With VIDchain, we create and manage decentralized digital self-sovereign identities (SSI) and credentials.  These credentials have the information structured and broken down as attributes so that automated services can be designed with smart contracts that use these credentials.

We can identify three leading roles in an SSI model:

The person who owns and manages their identities and attributes
The recognized entity that certifies with its signature the subject's identity and attributes and records the trace in the blockchain to verify it.
The entity or service portal that requires the user to identify and verify attributes through the trace embedded in the blockchain; and parse the data shared by the user for the business process.
