Verification of peer-to-peer network transmission occurs implementing AI to determine a match between the purpose / intent of the peer-to-peer network transmission as defined by the sending entity / peer and the purpose / intent of the peer-to-peer network transmission as defined by the recipient entity / peer. The sending peer initiates communication of a peer-to-peer network transmission, which identifies the recipient peer and purpose of the transmission. The peer-to-peer network transmission is captured and held in a transmission pending queue. A push notification is communicated to the recipient entity / peer identified in the transmission, which requests input of their perceived purpose / intent of the transmission. Once the recipient entity / peer identified in the transmission responds with their purpose of the transmission, an AI model trained to determined matches between inputted purposes / intents is executed. Once the AI model determines a purpose / intent match, the transmission is released for the transmission pending queue, so that further communication and / or processing of the transmission occurs.
