What are endorsements and how are they captured?
On the iov42 platform, endorsements are captured by the use of cryptographic signatures. An endorsing party, independent of the identity holder, can endorse an identity's claim.
The trust conveyed to a claim is dependent on who the endorsing party is and whether their identity contributes to the validity of the claim. For example, you would expect that the endorsement of your nationality by the Passport Office would convey a high level of trustworthiness for that particular claim, whereas the same endorsement by your hairdresser would not have the same level of trustworthiness.
Once an endorsing party signs a claim, it is submitted to the iov42 network, where it goes through consensus for validation. Once validated, the claim and related endorsement are added to the identity to enable a richer expression of the identity, which can later be used to assert trust in trusted transactions.
