Internet is a fundamental tool in our day to day. Internet purchases and banking operations no longer have any mystery for us. But, despite its advantages, performing these activities safely has been a challenge for specialists. The blockchain networks respond precisely to this need and guarantee greater security.
But ... what exactly are the blockchain? Surely you've heard about them lately, especially in news about bitcoin cryptocurrency. The chain of blocks eliminates, explaining it in a simple way, any type of intermediary in a transaction. When making any kind of virtual exchange we give the order, but not the process, it is a third party (a computer program) that executes it, completes and notifies the other user. Complicated? Let's say we have no control over the exchange process, that information is only known by the program that makes it.
The blockchain networks aim to give us control over any type of virtual transaction in a completely secure way. How can it be so safe? The chain of blocks, unlike the current system, consists of numerous nodes that record the information in a synchronized way, so that if one fails the information is still present in all the others. This large database allows only to record new data, not modify it, which makes an attack much more complicated.
What can the blockchains be used for? The simplification of the system, the speed of transactions and the reduction of costs can be attractive to sectors such as commerce or online data storage. The open and community nature of this new system has become the main attraction for startups focused on innovation.
