Abstract
Disclosed are various embodiments for offline decentralized identity-based communications between software applications. In one non-limiting example, a system can include a computing device that is configured to detect a network connection loss to a network and receive, via a local area network, a request for an action to be performed by a client device. The request includes a first digital signature of the client device and is associated with a decentralized identifier. The computing device is configured to generate a mutually signed request that includes a second digital signature executed by the computing device and the first digital signature. The mutually signed request is transmitted to the client device. A network connection to the network is detected. The decentralized identifier is validated using the network. The requested action is performed by the computing device based at least in part on the validation of the decentralized identifier.
