Smart contracts, blockchains (distributed ledgers), and rights management broadly construed are the themes of today's Spotlight Patents. A rare 3-fur today. Assigned to IBM, the first patent addresses techniques implementing a right to be forgotten on an immutable ledger. Assigned to Cisco, the second patent addresses techniques for decentralized content distribution. Assigned to Eluvio the third patent addresses techniques for a decentralized content fabric.

An example operation may include one or more of receiving a transaction request into at least one node of a blockchain network, the transaction request comprising one or more transaction parameters and one or more encryption keys, processing the transaction request to produce a transaction result, encrypting one or more parameters of the transaction result to produce an encrypted transaction result, storing the encrypted transaction result in a data block of the blockchain, and storing the one or more encryption keys in one or more key stores of the blockchain network.

In one embodiment, a computing device includes: a media player operative to at least play a content item on the computing device, a blockchain-based wallet application operative to transfer a transaction amount to a publisher wallet ID via an associated blockchain-based transaction service, a secure digital rights management (DRM) client application operative to verify the transfer of the transaction amount to said publisher wallet ID according to a public transaction ledger associated with the associated blockchain-based transaction service and upon successful verification of the transfer of the transaction amount to the publisher wallet ID at least unlock a locked version of the content item, and a processor operative to execute the media player, the blockchain-based wallet application, and the DRM client application.

Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of digital content retrieval using a decentralized content fabric. In some implementations, fabric nodes of an overlay network are provided. A first fabric node is configured to: determine, responsive to a client request for a content object part, that the content object part is not stored locally at the first fabric node; identify a second one or more fabric nodes as a best match; send a network request for the content object part to the second one or more fabric nodes; obtain the content object part from the second one or more fabric nodes; and process the content object part with further content object parts to produce the digital content for the client.
