Abstract
An electronic device of a content producer generates a chunk of data, associates a location-independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key. A user device may obtain the public key and use it to verify the chunk of data.
