The Berlin-based company BOTLabs, founded by Ingo Rübe and Hubert Burda Media, is developing the blockchain-based KILT Protocol: KILT’s goal is to establish a trust market to confirm claims. Attesters thus have the opportunity to monetise existing trust and verifiers benefit from structures that allow them to trust Attesters. The basis for this trust market is that market participants agree on common standards (CTYPES) to describe properties.
The KILT Protocol provides mechanisms that allow this process to be transferred from the real world to the digital world. Having made an assertation, or ‘claim’, the Claimer is issued with a Credential by an Attester. This Credential is stored under the control of the Claimer. In this way, data silos and monopolies are prevented.
What are known as CTYPES ensure the contents of the communication can be understood. The aim is to present the contents of a claim to all three players (Claimer, Attester, Verifier) in an understandable and uniform way. The KILT- Protocol offers the construct of the claim type (CTYPE). CTYPEs describe the content and structure of a claim, e.g. the fields that must be present on a driving licence, such as name, driving licence class and issue date.
