This specification describes how real-world service providers and consumers interact using the Videre Protocol to effect an exchange of a service.

This allows any service provider to create an industry-specific marketplace on which to advertise their inventory in a permissionless, decentralised manner.

Design requirements

  • Anonymity: Consumers who are searching for inventory should not have any identifying information conveyed to the service provider.
  • Transparency: All actors bearing witness to the exchange must be able to see clearly the terms by which services are exchanged.
  • Data ownership: Service providers must be able to completely control their inventory. This control may be delegated.
  • Decentralised: The protocol must be permissionless, relying on no centralised infrastructure.


  • Anonymity as protection against an adversarial business targetting users with aggressive pricing strategies.
  • Transparency allowing all in the marketplace to see the prices being offered and settled (akin to an L2 orderbook).
  • Data ownership to prevent vendor lock-in and subsequent rent extraction techniques.


Line refers to an industry that has an implementation.

Service provider refers to an entity providing an intangible act for which another party is willing to pay for.

Consumer refers to the party purchasing the intangible act.

Stub represents a service owed by the service provider to the consumer subject to terms.

Messaging system refers to the chosen protocol on which the service provider and consumer have agreed to communicate.

Personally identifiable information (PII) refers to any piece of data that can be used to uniquely identify a user. For example, the signature verification key, and the hash of one's static IP address are unique for each user and hence count as PII.
