Creating a portfolio of blockchain-encoded rived longevity-contingent instruments

A computing device of a computing system, the computing device comprises:

• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• obtain a rive approach for riving a set of longevity-contingent instruments of a multitude of available longevity-contingent instruments based on rive approach requirements, wherein a first longevity-contingent instrument of the set of longevity-contingent instruments includes a first face value benefit and a first premium payment stream, wherein a second longevity-contingent instrument of the set of longevity-contingent instruments includes a second face value benefit and a second premium payment stream, wherein, when available, a first portion of the first face value benefit is utilized to fund at least some of the second premium payment stream in accordance with the rive approach;
• verify authenticity of a group of blockchain-encoded records representing a subset of the multitude of available longevity-contingent instruments to produce an authenticity indicator, wherein the subset of the multitude of available longevity-contingent instruments includes the first longevity-contingent instrument and the second longevity-contingent instrument;
• and
• when the authenticity indicator for the group of blockchain-encoded records is favorable:
• select the first longevity-contingent instrument and the second longevity-contingent instrument based on the rive approach to produce the set of longevity-contingent instruments;
• and
• update a first blockchain-encoded record for the first longevity-contingent instrument and a second blockchain-encoded record for the second longevity-contingent instrument to include selection information, wherein the group of blockchain-encoded records includes the first and second blockchain-encoded records.

A computer readable memory comprises:

• a first memory element that stores operational instructions that, when executed by a processing module of a computing device, causes the processing module to:
• obtain a rive approach for riving a set of longevity-contingent instruments of a multitude of available longevity-contingent instruments based on rive approach requirements, wherein a first longevity-contingent instrument of the set of longevity-contingent instruments includes a first face value benefit and a first premium payment stream, wherein a second longevity-contingent instrument of the set of longevity-contingent instruments includes a second face value benefit and a second premium payment stream, wherein, when available, a first portion of the first face value benefit is utilized to fund at least some of the second premium payment stream in accordance with the rive approach;
• a second memory element that stores operational instructions that, when executed by the processing module, causes the processing module to:
• verify authenticity of a group of blockchain-encoded records representing a subset of the multitude of available longevity-contingent instruments to produce an authenticity indicator, wherein the subset of the multitude of available longevity-contingent instruments includes the first longevity-contingent instrument and the second longevity-contingent instrument;
• and
• a third memory element that stores operational instructions that, when executed by the processing module, causes the processing module to:
• when the authenticity indicator for the group of blockchain-encoded records is favorable:
• select the first longevity-contingent instrument and the second longevity-contingent instrument based on the rive approach to produce the set of longevity-contingent instruments;
• and
• update a first blockchain-encoded record for the first longevity-contingent instrument and a second blockchain-encoded record for the second longevity-contingent instrument to include selection information, wherein the group of blockchain-encoded records includes the first and second blockchain-encoded records.
