Data gap bridging methods and systems

A non-transitory computer readable medium comprising computer executable instructions stored thereon that, when executed by a processor in a source system, cause the processor to:

• receive, at a downlink monitor, a sent data volume from an external computing device of a vendor by sending a secure counter check to the external computing device;
• determine, by an uplink monitor, an operator received data volume from the vendor based on a charging function;
• receive a first charging data report (CDR) including the sent data volume from a vendor;
• compare the first CDR to an operator received data volume and when the first CDR is different than the operator received data volume, rejecting the first charging report;
• provide a second CDR having the operator received data volume to the vendor;
• receive a charging data acceptance including a negotiated data volume from the vendor derived from calculating a constraint-bound charge range between the sent data volume and the operator received data volume based on a representation of the sent data volume relative to the received data volume allowing reconciliation of the difference therebetween;
• construct a publicly verifiable proof of charging based on the charging data acceptance;
• and
• send the publicly verifiable proof of charging to the vendor.
