Abstract: An identity disambiguation data is received via a communication interface. A distributed identity disambiguation repository is used to determine whether the identity disambiguation data has been used previously to establish a digital identity. In response to a determination made using the distributed identity disambiguation repository that the identity disambiguation data has not been used previously to establish a digital identity a globally-unique digital identity is issued based at least in part on the identity disambiguation data. The identity disambiguation data comprises data that is unique to one human user.

Abstract: A unified authentication system for decentralized identity platforms is disclosed. In various embodiments, a request comprising one or more identity claims and a digital address is received. The digital address is used to verify, via a verification node associated with a digital address provider, the one or more identity claims. Access to a service is provided, in response to the request, based at least in part on a response from the verification node indicating the one or more identity claims have been verified. The verification node is configured to obtain consent, in real time, from a user with which the digital address is associated, prior to providing said response indicating the one or more identity claims have been verified.

Abstract: Proxied cross-ledger authentication techniques are disclosed. In various embodiments, a verifier presentation requirement is determined, the verifier presentation requirement indicating a set of elements required to be provided by a client to authenticate the client. An authentication contract instance is created on a market maker ledger not associated specifically with the verifier, the authentication contract instance including at least a subset of the elements required by the verifier presentation requirement. A verifier system associated with the verifier presentation requirement is configured to read information from the authentication contract instance, obtain from an issuer associated with the client an issuer revocation data associated with the authentication contract instance, and use the information read from the authentication contract instance and the issuer revocation data to authenticate the client.

Abstract: Techniques are disclosed to provide enforceable pseudonymous reputation through chained endorsers. In various embodiments, a request associated with a chained endorsement operation is received via a communication interface. A client identity information is extracted from the request. Data comprising or associated with the client identity information is combined with a secret value. A one-way transform of the combined value is performed. A result of the one-way transform is returned to a client with which the chained endorsement operation is associated.
