Blockchain or distributed ledger, names that the blockchain also receives, constitute a distributed database that records blocks of information and interlaces them to facilitate the retrieval of information and verify that they have not been modified.
By transferring this information into practice, blockchain technology allows decentralized, transparent, open transactions and contracts that shield privacy, guaranteeing extreme security and the same protocol for all participants, that is, it allows an anonymous movement, with total privacy between the data of both interested parties. It has already been compared by experts with historical milestones of innovation such as the emergence of the Internet.
On the other hand, the expansion of cryptocurrencies, such as bitcoin, which have their stock market, changes payment methods and traditional money. The digital revolution and P2P (peer-to-peer) technology applied to cryptocurrencies implies a low risk and works between user platforms, through consensus among all. Today, they can be bought and sold easily, just as their trend will only grow shortly.
Among many other applications, the blockchain allows you to carry out Smart contracts, allowing you to securely connect the devices linked to the Internet of Things, democratize the electoral system through electronic voting, improve eCommerce and encourage the collaborative economy, assess the traceability of food, ensure more efficient logistics operations or make the flow of goods and money from any commercial process verifiable at any point in the supply chain.
The complex revolution that the blockchain represents, can be executed in all sectors, benefiting for example the leisure and entertainment industry allowing to preserve the copyright or regulate the economic compensation of the artists, to the security forces by allowing real-time monitoring o transparent access to databases or the transport industry, facilitating the identification of passengers.
While a decade ago the word did not sound even in a tiny portion of mouths compared to the current moment, the blockchain, popularized by the emerging fame, although criticized, of Bitcoin and other virtual currencies, comes from the hand of a broad riotous potential that can affect areas as diverse as politics, economy, commerce, leisure, cybersecurity, law, logistics, arms possession, Artificial Intelligence, business team management, cloud storage or the gaming
Blockchain technology generates transparent and faithful information, it is changing the way bank transactions are carried out, the way money and the labor market are conceived in the global context. Beyond this, it allows the storage of data in a way that did not exist before, just as the encryption of the information can be done more reliably.
Another consequence of blockchain in society is its inclusion in the labor market. If large numbers of computer scientists are already demanded today, sometimes more than can be filled, the demands of blockchain developers cover the largest quota of these vacancies.
All this is just the beginning of a large market full of profits for various sectors such as health, finance, and banking, insurance or insurtech, food or education, all of them thanks to the touch of digital transformation at this point in the XXI century.
Today, the question is, which industry cannot benefit from the impact of the blockchain?
