Some of the use-cases are:
Medical records are notoriously scattered and erroneous, with inconsistent data handling processes meaning hospitals and clinics are often forced to work with incorrect or incomplete patient records. Healthcare projects such as MedRec are using the blockchain as a means of facilitating data sharing while providing authentication and maintaining confidentiality.
One of the main benefits of blockchain technology is the way it removes intermediaries or middlemen. The music business is a prime example of an industry whose inefficiencies have seen artists poorly remunerated for their efforts. A number of blockchain-based projects have sprung up seeking a fairer deal for music creators, including Artbit, overseen by former Guns N Roses drummer Matt Sorum.
Ukraine holds the honor of becoming the first nation to use blockchain to facilitate a property deal. A property in Kiev was sold by prominent cryptocurrency advocate and TechCrunch founder Michael Arrington. The deal was enabled with the aid of smart contracts on the Ethereum blockchain, and is intended to be the first of many completed by Propy, a startup specializing in blockchain-based real estate deals.
Blockchain is now being used to support sustainable fishing. Illegally caught fish is an endemic problem within the industry, and distributed ledger technology provides a means of proving where fish were caught, processed and sold. This ‘net-to-plate’ chain allows inspectors to determine whether fish had come from regions notorious for human rights abuses or from countries that are affected by economic sanctions.
Blockchain is being researched as a means of improving Hawaii’s economy by giving tourists an opportunity to pay for local goods and services with bitcoin and other currencies. This way the state’s government hopes to attract tourists, especially from Asia, to spend more money and eventually help Hawaii to develop economically.
