receiving a first fingerprint of a first phone event, by a user device of a first recipient in the first phone event;
automatically detecting, by the user device without an input of the first recipient, a first behavior of a first recipient with respect to the first phone event;
automatically determining, by the user device, that the first phone event is a target phone event based on the first behavior of the first recipient detected by the user device;
batching at least one of the first fingerprint of the first phone event or the first behavior of the first recipient into a transaction data;
broadcasting the transaction data to nodes of a blockchain network for each of the nodes to add the transaction data into a respective copy of a blockchain maintained at the node.
