The blockchain is a concept that poses a huge revolution not only in our economy but in all types of fields. Now you can use this technology to develop systems and apps to conduct highly transparent, secure and agile transactions as well as data collection.

Blockchain eliminates intermediaries, decentralizing all management. The control of the process is of the users, not of the banks – we continue talking about money, but the example is extrapolated to other types of transactions -, and it is they who basically become part of a huge bank with thousands, millions of nodes, each of which becomes a participant and manager of the bank account books.
What is the blockchain then? Well, a giant account book in which records (blocks) are linked and encrypted to protect the security and privacy of transactions. It is, in other words, a distributed and secure database (thanks to encryption) that can be applied to all types of transactions that do not necessarily have to be economical.
Blockchain has an important requirement: there must be several users (nodes) that are responsible for verifying those transactions to validate them and thus the block corresponding to that transaction (in each block there is a large number of transactions that yes, it is variable) register in that gigantic account book.
Property Registration
The Japanese government has initiated a project to unify the entire registry of urban and rustic properties with blockchain technology, which would allow for an open database in which the 230 million data could be consulted of farms and 50 million buildings estimated to exist in the Asian country. In Dubai, they are planning something very similar.
Payments in The Real World
A startup called TenX has created a prepaid card that can be recharged with different cryptocurrencies and then paid with it anywhere as if that card had conventional money, regardless of whether or not that establishment accepts such currencies virtual
Carsharing
EY, a subsidiary of Ernst & Young Global Ltd, is developing a system based on the blockchain that allows companies or groups of people to access a car-sharing service easily. The so-called Tesseract would allow registering who owns the vehicle, the user of that vehicle and generate costs based on insurance and other transactions in this type of service.
Cloud Storage
Storage services are usually centralized at a specific provider, but the Storj company wants to decentralize this service to improve security and reduce dependence on that storage provider.
Digital Identity
The last gigantic security flaws and data thefts have made the management of our identities become a very real problem. The blockchain could provide a unique system to validate identities in an irrefutable, secure and immutable way. There are many companies developing services in this area, and they all believe that applying blockchain technology for this purpose is an optimal solution.
Music
Although there are criticisms that affirm that this option is not valid, there are those who affirm that the musical distribution could suffer a whole revolution if a system based on the blockchain was managed to manage its reproduction, distribution, and enjoyment. The Spotify itself is betting heavily on its own blockchain.
Public/Government Services
Another of the most interesting areas of blockchain application is in public services that could thus boast absolute transparency. The areas of activity are multiple: from license management, transactions, events, movement of resources and payments, property management to identity management. In fact, massive data theft in Equifax has led some to propose the replacement of social security numbers in the United States with a blockchain-based system. There are initiatives even to “decentralize government”, and Bitnation. It is one of those projects that try to call us to become “citizens of the world.”
Social Security and Health
Although it could be included in the mentioned public services, public health could suffer a real revolution with a blockchain system that would serve to record all types of medical records and solve one of the classic management problems of healing.
Management of Authorships
Although related to the aforementioned for the world of music, Ascribe is a platform that tries to help creators and artists to attribute the authorship of their works through the blockchain. There are many other platforms in this area (Bitproof, Block, Stampery, for example) that among other things allow you to generate stores where you can buy original works in a safe and simple way.
