Methods and systems are described for implementing decentralized digital rights management (DRM) within a decentralized network, satisfying an important need of content owners. First, the method implemented by a source cacher node includes broadcasting, to one or more viewer peer nodes in the decentralized network, a notification of the source cacher node’s intent to transmit a data stream. Then, recording a smart contract on a blockchain associated with the decentralized network, the smart contract associated with the data stream and allowing the authentication of a viewer peer node through the smart contract by an ownership of a non-fungible token (NFT) in order to receive a data key to decrypt the data stream. Next, receiving a request from an authenticated viewer peer node for receiving the data stream. Finally, generating an encrypted data stream based on the data stream and the data key to decrypt the data stream, and transmitting the encrypted data stream and the data key to the authenticated viewer peer node.
