Published: with international search report (Art. 21(3)) (54) Title: BLOCKCHAIN-IMPLEMENTED METHOD FOR CONTROL AND DISTRIBUTION OF DIGITAL CONTENT (57) : The disclosure relates to a blockchain-implemented system and method of controlling the transmission and/or distribution of digital con- tent. In an illustrative embodiment, the blockchain is the Bitcoin blockchain. The first user (5) is associated with a deposit quantity of cryptocurrency at a common address (23), wherein to spend from the common address requires signatures of both a first private key of the first user (5) and a second private key of the second user (7). The system (1) comprises a first node (15) and a second node (17).- The first node (15) is associated with a first user (5) com- prising a first processing device configured to: (A) send, over a communica- tions network (8), a request to the second node (17) to provide an episode of digital content from a series of digital content; (B) determine a payment transaction (27) to transfer from a common address (23) a payment quantity Content server of cryptocurrency to the second user (7), wherein the payment quantity of 3 cryptocurrency is based on a quantity of episodes of digital content in the series of digital content requested by the first user (5); and (C) sign, with the first private key (V ), the payment transaction (27) and subsequently send the payment transaction (27) to the second node (17). The second node (17) is associated with the second user (7) comprising a second processing device configured to: (I) receive, over the communications network (8), the request from the first node (15) to provide the episode of digital content and the pay- ment transaction (27), signed with the first private key; (II) verify the pay- ment transaction, comprising verifying that the payment transaction includes the payment quantity of cryptocurrency to the second user (7), and based on Fig. 1 the result of verifying the second processing device is further configured to: (III) provide access, over the communications network (8), to the episode of digital content (i) to be available to the first node (15); and (IV) co-sign, with the second private key of the second user (5), the pay- ment transaction and send the co-signed payment transaction to a distributed ledger (blockchain) (9).
