The system can receive and store patient healthcare data from sources such as wearable devices, an implant, patient devices, healthcare provider devices, databases, cloud storage accounts, healthcare databases, or digital filing cabinets. The system can convert the healthcare into non-fungible tokens on a blockchain to protect the healthcare data from being accessed by nefarious actors. The system can manage access to the healthcare data based on authentication rules. ## Claims ### Claim 1 A computer-implemented method for providing patient-specific healthcare data using a non-fungible token platform, the method comprising: receiving the patient-specific healthcare data of a patient from at least one input data source, wherein the patient-specific healthcare data is associated with a blockchain-enabled medical implant implanted in a body of the patient;
