Use cases
Crypto-currency is just one of the use-cases of Blockchain. There are potentially many more use-cases with far reaching implication on Business and everyday life.
Blockchain in Supply chain and Finance
Use-cases of Blockchain in Supply chain and Finance are the most talked about use cases, and there are many demonstrations available freely on the internet. I recommend you watching the following videos from Youtube while I list down Usecases from other industries, that are less talked about.
Blockchain in the Energy Industry
Energy value chain has multi-party interaction that needs to happen through a secured well managed network, making this industry a suitable candidate for Blockchain use-cases.
Tracking energy certificate: Renewable energy certificate from certifying agencies has clauses and an a life-cycle which undergoes mutation and consequently needs to me monitored and managed.
Smart metering: In a smart grid, there are consumers and well a pro-sumers (who both consume and produce from their solar panels). Blockchain can manage billing much more effeciently. In a broader case, Blockchain can facilitate energy trading.
Blockchain in Media Industry
Blockchain has potential use-cases in Media too.
Attribution: Licence management, Royalty payments and other revenue flow relies upon the correct attribute of the content. Attribute management can be complex specially if the content is co-created by multiple parties. Blockchain, with is property of provenance (secure tracking) is ideal to manage content attribute and rights.
Payment and Accounting: Distribution, Marketing and Artists forms a functional consortium with agreed upon terms and conditions. These terms can be codified and managed by Smart contracts in a Blockchain.
Integrity Check: Blockchain, can also be used to check the integrity of a media content. Any tamper with a content will generate a different hash value from the original content.
Blockchain in Identity Management
Blockchain has tremendous potential in identity management. Digital version of a existing identity such as passport, marriage certificate, drivers license etc managed by a Blockchain application will give more control to the individual and provide much needed security.
2way, atencoin, blockcauth are some of the companies working of Blockchain based identity solution. Here is a more exhaustive list of companies in this space: https://letstalkpayments.com/22-companies-leveraging-blockchain-for-identity-management-and-authentication/
Blockchain in Telecommunication
Communication service providers can utilize Blockchain across the entire value chain but specifically- Network management, Customer management, Partner management and Enterprise management.
Top use-cases are:
Roaming fraud prevention: Usually, the data clearing houses handle the TAP files generated during a roaming call. Roaming fraud occurs when the Home private mobile network is unable to charge the subscriber for that call made via Visited private mobile network. Fraud detection and response time is prolonged due to lack of single view of and control over disparate systems. A blockchain between a pair of operators can do away with the data broker and can implement smart contracts to self execute roaming agreements.
Identity and Data management: CSPs can tap into new sources of revenue by providing Identity management and data integrity management services.
IoT management: Blockchain can be used to create a self-manged network of sensors bypassing the need for regional routing thus making charging and billing seamless and enforcing greater data security.
