When people hear the word blockchain, the primary term that often comes to mind is cryptocurrency, notably Bitcoin. even though it is the fact that blockchain was established to underlie digital currencies, its tendrils spread into a plethora of fields, far beyond just financial transactions.

Nowadays, people from all walks of life, in many different industries, are investigating the technology's core value prop—to store, verify, and manage data absolutely securely. This article will focus on three very different use cases for blockchain.

Supply Chain Transparency

For blockchain technology Supply chain  is the most promising application . When a good moves from the manufacturer to the consumer, it travels through a series of complex, often redundant, and sometimes outdated systems. In many cases, these systems involve not just the manufacturer and the consumer but also a number of middlemen providers of logistics; suppliers of services, equipment, and forms of energy; and some combination of wholesalers and retailers all of which layer on additional costs. Tracking the good through this series of parties is no easy feat. Problems associated with the traditional supply chain can be minimized or solved completely with the use of blockchain technology.

Improving Healthcare Data Management

Waves are also being made in the healthcare industry—by blockchain. This emerging technology is being touted as an efficient and safe means to manage medical records. Each record is linked to a unique digital key, accessible only to authorized individuals like patients or their healthcare providers. This makes for a highly secure and shareable set of medical data that can be, when required, easily accessed by any number of hospitals, clinics, or laboratories. Moreover, blockchain can monitor the originality and transport of drugs, lessening the chance of fake medicines penetrating the industry. It accomplishes this by archiving every deal in a drug's life, from the maker to the druggist, and in so doing establishes a valuable system for both doctors and patients.

Digital Identities

In the digital era, individuals avail themselves of countless online services. For these services, they create a number of usernames and passwords. These, too, can be stolen or hacked. The use of online services has made individuals far more vulnerable to identity theft. And the possibility of data breaches has become an ever-present concern for both individuals and organizations. Blockchain provides a solution in that it allows users to create a singular, secure digital identity that can be used across a multitude of platforms. This identity is not only encrypted, but is also stored on a blockchain, a medium that affords the user much more control over their personal information than do the large corporations that currently store the identities of their users in centralized databases. In the case of blockchain, the sender can identify, even down to the level of individual bits of data, which gets access to the information and for how long. Experiments are being conducted by governments and private companies with digital identity systems based on blockchain technology.

Conclusion

To sum up, although cryptocurrencies first brought blockchain technology into the limelight, the technology's uses now extend well beyond the realm of digital money. Here are a few ways that various industries are using blockchain—improving the clarity and trustworthiness of the information they work with: - Supply chains are using it to better manage and share information with all the partners in their ecosystem. - Healthcare organizations are using it to secure the information necessary to safeguard their patient constituents.
