## Abstract

The present disclosure provides blockchain computing systems and methods of using same.

## Claims

### Claim 1

A computer-based method comprising:
providing a blockchain computing system that stores and maintains a blockchain ledger, wherein the blockchain computing system hosts: (i) an encrypted electronic health record associated with a patient, and (ii) a smart contract that uses the blockchain ledger to verify blockchain transactions with the smart contract;
providing an off-chain computer system comprising:
a third-party module configured to enable a healthcare provider to generate a smart contract to incentivize a patient to complete a task, purchase a product, or purchase and receive a service, wherein the smart contract is published to the blockchain ledger,
a patient module configured to enable the patient to: (i) selectively grant access to at least a portion of the encrypted electronic health record associated with the patient to an authorized doctor, (ii) generate a request to execute the smart contract, and (iii) perform a task associated with the smart contract, and
a doctor module configured to enable the authorized doctor to: (i) access the encrypted electronic health record, and (ii) generate a request to publish a block to the blockchain ledger, wherein the block includes updated medical information about the patient;
receiving, by the blockchain computing system, a request by the patient to execute the smart contract via a blockchain transaction;
verifying, by the blockchain computing system, that the blockchain transaction satisfies the smart contract; and
transferring, if the blockchain transaction satisfies the smart contract, a blockchain token to a digital wallet associated with the patient, wherein the patient module is configured to further enable the patient to: (v) perform a task associated with the smart contract, and
wherein the task is selected from the group consisting of: scheduling an appointment with a healthcare provider, attending a scheduled appointment with a healthcare provider, participating in a telemedicine consultation with a healthcare provider, viewing a video published to the off-chain computer system, reading an article published to the off-chain computer system, completing a survey published to the off-chain computer system, publishing an inquiry to the off-chain computer system, granting access to at least a portion of the encrypted electronic health record associated with the patient, retrieving a purchased prescribed medication, retrieving a prescribed test, receiving a prescribed treatment, playing a sponsored game, and applying to participate in a clinical study.

### Claim 2 (depends on 1)

The computer-based method of claim 1, wherein the product to be purchased is a health-related product.

### Claim 3 (depends on 2)

The computer-based method of claim 2, wherein the health-related product is a health monitoring device, an over-the-counter medication, a prescribed pharmaceutical, an exercise device, a health club membership, an orthopedic product, or a healthy food.

### Claim 4 (depends on 1)

The computer-based method of claim 1, wherein the service to be purchased and received is related to improving or maintaining the patient's health.

### Claim 5 (depends on 1)

The computer-based method of claim 1, wherein the authorized healthcare provider is a clinical research organization, and wherein the task is applying to participate in a clinical study associated with the clinical research organization.

### Claim 6 (depends on 5)

The computer-based method of claim 5, wherein the step of enabling the patient to selectively grant access to the portion of the encrypted electronic health record associated with the patient includes granting access to the patient's age, gender, and country of residence.

### Claim 7 (depends on 6)

The computer-based method of claim 6, wherein the step of enabling the patient to selectively grant access to the portion of the encrypted electronic health record associated with the patient does not include granting access to the patient's patient-identifying information including the patient's name, address, telephone number, or email address.

### Claim 8 (depends on 5)

The computer-based method of claim 5, wherein the patient module is further configured to enable the patient to (i) accept an incentive offered by the contract research organization for the patient to enroll in the clinical study, or (ii) request an increased incentive from the contract research organization to enroll in the clinical study.

### Claim 9

A system comprising:
a blockchain computing system configured to:
(i) store and maintain a blockchain ledger, and
(ii) host a smart contract that uses the blockchain ledger to verify blockchain transactions with the smart contract; and
an off-chain computer system configured to:
(i) receive a request from the blockchain computing system associated with the smart contract,
(ii) enable an authorized healthcare provider to generate a smart contract to incentivize a patient to complete a task, purchase a product, or purchase and receive a service, wherein the smart contract is published to the blockchain ledger,
(iii) enable the patient to: (a) selectively grant access to at least a portion of the encrypted electronic health record associated with the patient to the authorized healthcare provider, and (b) generate a request to execute the smart contract, and
(iv) enable the authorized healthcare provider to: (a) access the encrypted electronic health record, and (b) generate a request to publish a block to the blockchain ledger, wherein the block includes updated medical information about the patient,
wherein the task is selected from the group consisting of: scheduling an appointment with the authorized healthcare provider or with a second healthcare provider, attending a scheduled appointment with the authorized healthcare provider or with a second healthcare provider, participating in a telemedicine consultation with the authorized healthcare provider or with a second healthcare provider, viewing a video published to the off-chain computer system, reading an article published to the off-chain computer system, completing a survey published to the off-chain computer system, publishing an inquiry to the off-chain computer system, granting access to at least a portion of the encrypted electronic health record associated with the patient, retrieving a purchased prescribed medication, retrieving a prescribed test, receiving a prescribed treatment, playing a sponsored game, and applying to participate in a clinical study.

### Claim 10 (depends on 9)

The system of claim 9, wherein the product to be purchased is a health-related product.

### Claim 11 (depends on 10)

The system of claim 10, wherein the health-related product is a health monitoring device, an over-the-counter medication, a prescribed pharmaceutical, an exercise device, a health club membership, an orthopedic product, or a healthy food.

### Claim 12 (depends on 9)

The system of claim 9, wherein the service to be purchased and received is related to improving or maintaining the patient's health.

### Claim 13 (depends on 9)

The system of claim 9, wherein the authorized healthcare provider is a clinical research organization, and wherein the task is applying to participate in a clinical study associated with the clinical research organization.

### Claim 14 (depends on 13)

### Claim 15 (depends on 14)

The system of claim 14, wherein the off-chain computer system is further configured to enable the patient to selectively grant access to the portion of the encrypted electronic health record associated with the patient without granting access to the patient's patient-identifying information including the patient's name, address, telephone number, or email address.

### Claim 16 (depends on 13)

The system of claim 13, wherein the off-chain computer system configured to enable the patient to (i) accept an incentive offered by the contract research organization for the patient to enroll in the clinical study, or (ii) request an increased incentive from the contract research organization to enroll in the clinical study.
