Imagine that you are walking down the street and, suddenly, a flying meerkat of gargantuan proportions lands in a square full of people, eats the ice cream of all the children in it, releases two huge squeals and goes as it has come .
Without a second to lose, a lie detector is placed to the 1,000 people who have witnessed and it is recorded exactly what they have seen.
Everyone tells the same story with identical details.
Would there be any doubt about the landing of the flying meerkat?
Blockchain: A technology that can change everything.
This is the fundamental principle behind the chain of blocks or Blockchain , a technology that has the power to change forever our relationship with the digital world.
Imagine a text file with two columns, where in one column it puts an identifier (example "abc") and in the other a number (example "34"). That is, "abc" corresponds to "34". Now imagine that this file could be in thousands of duplicate computers, with the assurance that nobody can alter it to treason but when legitimately something must be altered, in a matter of seconds, all are synchronized. Even if one of the thousands of computers disappeared from the network, nothing would happen. This is what Blockchain achieves and although its magic is much more complex and composed of more pieces such as cryptography, in essence that seeks: a distributed record resistant to synchronization and no need for trust between the members that comprise it. Something that had been trying to solve for decades and Bitcoin has achieved its creator, the unknown Satoshi Nakamoto .
