Decentralized, dynamic media key block for broadcast encryption

A system for a dynamic media key block, the system comprising:

• a memory;
• and
• a processor in communication with the memory, the processor being configured to perform operations comprising:
• segmenting a media key block into two or more subsets, wherein each of the two or more subsets are respectively associated with a particular group of receivers, and wherein each receiver of the particular group of receivers is in a blockchain network;
• receiving, from a first receiver, a request for permission to process the media key block;
• identifying which of the two or more subsets that the first receiver is associated;
• and
• providing a media key block value to the first receiver.
