The uses of blockchain have expanded. However, it was not considered a system for developing cryptocurrencies from the beginning. Since 1991 it has been considered a secure method of sharing data and information. And today, it is possible to easily share all kinds of files by uploading them to the blockchain network. Using a link, the person will perform the download smoothly.

What is blockchain?

Generally, when talking about blockchain, we think only of cryptocurrencies, but this term encompasses a much broader technology than is known. It is an encryption system and is defined as a decentralized database. That is, it is distributed in different nodes. Through this, you can make all kinds of secure transactions.

This technology is not something new. Its origin was in 1991. However, it did not achieve great notoriety. With the appearance of Bitcoin in 2008, the term became relevant, relating at all times to cryptocurrency. For this system to work, all nodes must be connected. This is how transactions can be verified and validated to register the block.
