Permitting a claims holder to get a limited verifiable credential leveraging off of a previously-issued verifiable credential. This is done by having the limited verifiable credential include only a selected subset of the verifiable claims present within the previously-issued verifiable credential. The limited verifiable credential may then be exposed to a relying entity computing system so that the relying entity computing system can verify any of the selected subset of verifiable claims, but not verifiable claims that are outside of the selected subset of verifiable claims.

Bootstrapping trust in decentralized identifiers (DIDs) includes in response to receiving a request from an entity associated with a DID in a decentralized system, obtaining a DID document associated with the DID, and extracting a linked domain that is linked to the DID from the DID document. The DID document contains data associated with the DID that is recorded on the distributed ledger. The request contains the DID and data associated with the DID. Metadata associated with the linked domain is then retrieved from a domain name system (DNS). Based on the metadata associated with the linked domain and the data associated with the DID contained in the request, a trust score, indicating trustworthiness of the DID, is generated.

Updating a verifiable claim so that a duration of the verifiable claim can be modified without direct user input. A plurality of verifiable claims that have previously been issued to a user are accessed by a computing system. The plurality of verifiable claims include duration metadata that defines a duration of each of the plurality of verifiable claims. The duration metadata of each of the plurality of verifiable claims is monitored to determine those of the plurality of verifiable claims that are set to expire based on the defined duration. For those verifiable claims that are set to expire, a request is made to a party that issued each verifiable claim for update information that is configured to modify the duration of each verifiable claim. In response to receiving the update information, the duration of each verifiable claim is automatically updated without the need for any direct user input.
