Systems and methods for maintaining distributed media content history and preferences

A method comprising:

• receiving, via one or more network devices within a local network, data records representing local activity associated with a user;
• storing the received data records via a first distributed ledger associated with the local network;
• receiving, from one or more remote computing devices associated with a requesting entity, a query requiring verification of a condition associated with the user;
• generating, based on the data records stored on the first distributed ledger, a zero-knowledge proof (ZKP) cryptographic output that validates the condition is met without revealing the underlying data records;
• and
• transmitting the generated ZKP cryptographic output to a network address to authorize an action by the requesting entity.

One or more tangible, non-transitory computer-readable media storing instructions that, when executed by the one or more processors of a computing system, cause the computing system to perform operations comprising:

• receiving, via one or more network devices within a local network, data records representing local activity associated with a user;
• storing the received data records via a first distributed ledger associated with the local network;
• receiving, from one or more remote computing devices associated with a requesting entity, a query requiring verification of a condition associated with the user;
• generating, based on the data records stored on the first distributed ledger, a zero-knowledge proof (ZKP) cryptographic output that validates the condition is met without revealing the underlying data records;
• and
• transmitting the generated ZKP cryptographic output to a network address to authorize an action by the requesting entity.
