  • Patent number: 12647408
    Abstract: A digital content contribution verification system in a decentralized network is described. In an implementation, digital content is obtained and a plurality of portions are located from the digital content. A decentralized identifier and verifiable credential are identified as associated with a respective portion of the plurality of portions. The decentralized identifier is resolvable to a respective node from a decentralized network of nodes individually configured to store, receive, and transmit data. Representations are displayed of the decentralized identifiers indicative of a respective entity and corresponding verifiable credentials validating a relationship of the respective entity with the respective portion.

  • Patent number: 12641069
    Abstract: Gating logic is described to control access based on verifiable credentials. The gating logic is employable in a variety of ways to leverage verifiable credentials in support of identity, qualifications, or other attributes of an entity, and may do so without exposing personal information. To do so, a software development kit is described in one or more examples that is configured to incorporate gating logic at a service provider system to leverage use of verifiable credentials.

  • Publication number: 20260129045
    Abstract: Decentralized trust establishment using sentiment documents is described. In an implementation, a decentralized network of nodes is generated. A first entity is associated with a select node of the nodes. A user interface is presented including one or more options at an edge device of the first entity. The options support inputs specifying identification of a second entity, sentiment regarding the second entity, and supporting information describing why the sentiment is expressed towards the second entity. A plurality of sentiment documents are collected, respectively, from the plurality of nodes of the decentralized network. A sentiment is determined as associated with an entity by processing the plurality of sentiment documents. The determined sentiment is output.

  • Patent number: 12619699
    Abstract: Technologies are described herein for improvements in the security of verifiable credentials. A method can include requesting, by a first decentralized identifier (DID) associated with a decentralized web node (DWN), a verifiable credential from a second DID, wherein the second DID is included in a pool of DIDs. The method also includes receiving, from the pool of DIDs and by the first DID, the verifiable credential. The method also includes receiving, from a third DID and at the first DID, a request to verify information associated with the first DID. The method also includes determining, at the DWN, that the verifiable credential includes the information requested by the third DID. The method also includes presenting, by the DWN, at least a portion of the verifiable credential to the third DID in response to determining that the verifiable credential includes the information.

  • Publication number: 20250200539
    Abstract: A decentralized node may generate a network of decentralized nodes individually configured to store, receive, and transmit data based on rules associated with the decentralized nodes. A decentralized node may associate a decentralized identity of an entity with a select decentralized node of the decentralized nodes. A decentralized node may present a user interface including one or more access controls at a edge device, the access controls configuring rules to be applied to third-party access and modification of decentralized identity data associated within the decentralized identity of the entity and stored at the selected decentralized node. A decentralized node may identify the decentralized identity data accessible to the select decentralized node based on the rules. A decentralized node may store the decentralized identity data within the decentralized identity associated with the entity at the select decentralized node.
