Servicing 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:
• verify authenticity of a first blockchain-encoded record representing a first longevity-contingent instrument of a plurality of longevity-contingent instruments to produce a verified first blockchain-encoded record, wherein the first longevity-contingent instrument is rived in accordance with a rive approach to produce a first sub-asset of a plurality of sub-assets and a first sub-liability of a plurality of sub-liabilities, wherein the first sub-liability is associated with a first premium payment stream of a plurality of premium payment streams of the plurality of sub-liabilities;
• and
• when the first longevity-contingent instrument is associated with an available and unfulfilled benefit status:
• determine fulfillment information for the first longevity-contingent instrument, wherein the fulfillment information includes a benefit payout of the first sub-asset facilitated by a payer computing device;
• update the first blockchain-encoded record for the first longevity-contingent instrument based on security information of the payer computing device to include the fulfillment information to produce an updated first blockchain-encoded record;
• and
• send, via the interface, the updated first blockchain-encoded record to the payer computing device to facilitate payment of the benefit payout of the first sub-asset.

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:
• verify authenticity of a first blockchain-encoded record representing a first longevity-contingent instrument of a plurality of longevity-contingent instruments to produce a verified first blockchain-encoded record, wherein the first longevity-contingent instrument is rived in accordance with a rive approach to produce a first sub-asset of a plurality of sub-assets and a first sub-liability of a plurality of sub-liabilities, wherein the first sub-liability is associated with a first premium payment stream of a plurality of premium payment streams of the plurality of sub-liabilities;
• and
• a second memory element that stores operational instructions that, when executed by the processing module, causes the processing module to:
• when the first longevity-contingent instrument is associated with an available and unfulfilled benefit status:
• determine fulfillment information for the first longevity-contingent instrument, wherein the fulfillment information includes a benefit payout of the first sub-asset facilitated by a payer computing device;
• update the first blockchain-encoded record for the first longevity-contingent instrument based on security information of the payer computing device to include the fulfillment information to produce an updated first blockchain-encoded record;
• and
• send the updated first blockchain-encoded record to the payer computing device to facilitate payment of the benefit payout of the first sub-asset.
