Healthcare transaction validation via blockchain proof-of work, systems and methods

A method of validating healthcare transactions, the method comprising:

• receiving, by a validation device, healthcare transaction data comprising at least one pointer to at least one electronic medical record regarding healthcare actions taken with respect to a healthcare stakeholder;
• obtaining, by the validation device, a historical block identifier from a healthcare historical blockchain representative of historical actions taken with respect to the stakeholder;
• receiving, by the validation device, a validity requirement of a validity block for the healthcare transaction data;
• calculating, by the validation device, the validity block for the health care transaction data according the validity requirement as a function of at least the following healthcare parameters:
• the historical block identifier and the health care transaction data;
• and
• causing the healthcare historical blockchain to be updated with the validity block.

A computer program product for validating at least one healthcare transaction, comprising one or more machine-readable instructions stored in a non-transitory computer readable medium, wherein the one or more machine-readable instructions, upon execution by at least one processor, perform processing comprising:

• receiving, by a validation device, healthcare transaction data comprising at least one pointer to at least one electronic medical record regarding healthcare actions taken with respect to a healthcare stakeholder;
• obtaining, by the validation device, a historical block identifier from a healthcare historical blockchain representative of historical actions taken with respect to the stakeholder;
• receiving, by the validation device, a validity requirement of a validity block for the healthcare transaction data;
• calculating, by the validation device, the validity block for the health care transaction data according the validity requirement as a function of at least one of the following healthcare parameters:
• the historical block identifier and the health care transaction data;
• and
• causing the healthcare historical blockchain to be updated with the validity block.

A system for validating at least one healthcare transaction, comprising:

• a plurality of computers in a computer network, the plurality of computers being configured to store a healthcare historical blockchain comprising one or more blocks comprising historical healthcare transaction data regarding historical actions taken with respect to a healthcare stakeholder;
• and
• at least one validation device coupled to the computer network and configured to:
• receive new healthcare transaction data corresponding to healthcare actions taken with respect to the healthcare stakeholder;
• receive from a first peer or an authority service on the computer network a historical block identifier corresponding to a block in the healthcare historical blockchain;
• receive a validity block calculated by one or more peers on the computer network, and;
• determine the validity of the validity block according to a validity requirement by calculating the validity block as a function of at least one of the following healthcare parameters:
• the historical block identifier, the new healthcare transaction data, and a value included in the validity block, the value being determined by the one or more peers on the computer network.
