A computing system for verifying a verifiable credential that includes a dynamic claim, the comprising system comprising: one or more processors; and one or more computer-readable media having thereon computer-executable instructions that are structured such that, when executed by the one or more processors, cause the computing system to perform a method for verifying a credential that includes a dynamic claim, the method comprising: accessing a verifiable credential presented by a claim holding computing system, the verifiable credential including a claim that identifies a property and subject, and in which an issuer of the claim entitles a holder of the claim to access an identified network location to retrieve a value corresponding to the property and subject of the claim, the verifiable credential also including instructions for proving the claim; and in response to accessing the verifiable credential, following the instructions to thereby prove the claim; and accessing the network location and retrieving the value; and correlating the retrieved value with the property so that the computing system accepts the property as having the retrieved value; the accessing of the network location and retrieving the value occurring at a first time, the method further comprising reusing the verifiable credential by: again accessing, at a second time after the first time, the network location to the value having a different second value when obtained the second time as compared to its first value when the remote value was obtained the first time; and correlating the second retrieved value with the property so that the computing system accepts the property as having the second remote value. one or more processors; and one or more computer-readable media having thereon computer-executable instructions that are structured such that, when executed by the one or more processors, cause the computing system to perform a method for verifying a credential that includes a dynamic claim, the method comprising: accessing a verifiable credential presented by a claim holding computing system, the verifiable credential including a claim that identifies a property and subject, and in which an issuer of the claim entitles a holder of the claim to access an identified network location to retrieve a value corresponding to the property and subject of the claim, the verifiable credential also including instructions for proving the claim;
