To begin, blockchain technology encompasses much over just Cryptocurrency, and vice versa. First, we'll define blockchain as a distributed, immutable ledger that may be used to record & verify transactions, keep tabs on assets, as well as establish trust between parties. As a group, we're going to investigate the meanings of these terms. Let us use the context of the future of healthcare to achieve that.

What is a Shared Ledger?

The term "Shared Ledger" is used to describe a database that can be accessed and updated by several users simultaneously. Material on the blockchain is updated whenever a new "block" is added to the "chain." If one party makes changes to the blockchain, those changes are broadcast instantly to all other participants, making them equal co-founders as well as co-developers of the different datasets. Think about a patient's EMR (Electronic Medical Record). In a blockchain-based electronic medical record system, both the patient and the treating doctors may make edits to the record in real time. For his or her part, the patient has the option of providing the doctor with the most recent findings from any outside diagnostic services.

What is an Immutable Ledger?

The fact that each new block in a blockchain can't be altered after it has been generated is what's meant by the term "immutable ledger." The 'hashing' procedure generates the distinct virtual IDs that are stored in a blockchain's data. Any tampering with information will be immediately detected. In addition, due to the decentralized structure of the blockchain, it is difficult to replicate any unlawful alteration across all distributed copies. Using an electronic medical record (EMR) as an example, the immutable nature of a blockchain-based EMR makes it trustworthy for hospital administration to assign physicians and for insurance firms to execute transparent payments.

Illustrations on Immutable and Shared Ledger

Those involved in the healthcare delivery system may all benefit from a digital method for "recording transactions" in a form that is accessible to all parties and cannot be altered after the fact. Following are some of the examples that you need to understand. First, a medical school might use a blockchain to issue diplomas. Graduating students and their future employers in the medical field may access these records immediately, allowing for the generation of credentials that have already been confirmed. Secondly, a business owner constructing a medical facility may confirm legal title to the property by consulting a distributed ledger of land titles. All past landowners may be recorded in such a blockchain, along with any problems that arose during the transfer or sale of the property. Thirdly, an investigator doing a clinical study may have the participating hospitals join a blockchain, which will safeguard the information and provide a central location from which it could be examined by independent parties.

Blockchain technology may help "track assets" in a more immediate way. The concept here is that when an object travels from spot to site, more information is added to the blockchain. As an example, think about the distribution of drugs. The process starts at the factory, from whence the product is sent to one or more warehouses through a fleet of delivery trucks. At some point, it winds up at a pharmacy, either a retail location or a medical clinic. At this point, it may be administered to a person as a therapeutic option. Tracing an item throughout its entire route is helpful for managing inventory as well as care plans, just as it would be in any other distribution network.

Constructing trust is crucial. In order to ensure trustworthiness as well as safety, blockchains are built to be open and distributed to all participants. This is especially useful in the healthcare industry, where a high degree of trust is essential and is sometimes taken for granted. In the pharma supply-chain model, it is believed that both the production facility as well as the medications it produces have the necessary registrations and permissions, such as with the US Food and Drug Administration (FDA) as well as the Drug Controller General of India (DCGI), respectively. Additionally, the patient must have faith that the medication they get at the pharmacy has not been tampered with or switched out for a fake.

A blockchain may be used to confirm everything and keep faith in the system intact. Trustworthy information as well as safe digitalization would be essential for the growth of healthcare 5.0. Yet, there are obstacles that must be conquered. Scale is the most crucial of these factors. Hashing is a technically as well as energy-intensive operation. More efficient processing is necessary if blockchain is to spread beyond the Cryptocurrency industry. The volume and complexity of medical records are additional dimensions of dimension. The already complicated task of securely storing huge volumes of data on a blockchain is made much more so by the need to comply with regulations like HIPAA and GDPR.

The Bottomline

Options to the blockchain may emerge in the next few years. One such option is hashgraph, which is used by Hedera in the development of their smart contracts. The Mayo Clinic's SAFE digital health platform has included this innovation to confirm the results of Covid-19 tests as well as the health of its users. Smart contracts among healthcare providers and patients are fueling the growth of similar digital health technologies. The next generation of blockchain technology is set to revolutionize the healthcare system.
