What is blockchain technology?<\/b> Do you know what it is for? Before delving into this concept, you should know its origin, which dates back to 2008 and a group of programmers who worked under the pseudonym of Satoshi Nakamoto.<\/span><\/p>\n

\n

In fact, the beginning of the Blockchain takes place with the design of the first cryptocurrency. That is, Bitcoin.<\/span><\/p>\n<\/blockquote>\n

This cryptocurrency was realised under the P2P or peer-to-peer protocol. Over the years, however, the blockchain has developed other applications. <\/span>Find out more with our unique beginner's guide to Blockchain: Types, uses and benefits.<\/b><\/p>\n

Blockchain: what is it and what is it for?<\/span><\/h2>\n
\n

\"Blockchain\" refers to a blockchain in a distributed database. In other words, a digital ledger, which is stored in different data.<\/span><\/p>\n<\/blockquote>\n

Consequently, access to such data, to carry out transactions, will not be possible on a single computer; it will be possible on a number of computers. <\/span>different devices connected to the internet<\/b>.<\/span><\/p>\n

On the other hand, an important feature of this blockchain technology is that it <\/span>information cannot be deleted<\/b>. It will only be updated and always with the support of the vast majority of users accessing this 'digital ledger'.<\/span><\/p>\n

It is also worth noting that blockchain <\/span>is not only used in the financial sector<\/b>. In this beginner's guide to blockchain, we will see later on which sectors or industries we can apply it to.<\/span><\/p>\n

How does blockchain work?<\/span><\/h2>\n

Do you know how blockchain technology works? We tell you in 3 steps:<\/span><\/h4>\n

1. Transaction, equals block<\/span><\/h3>\n

Each transaction recorded in this digital ledger is recorded as a block of data.<\/b> In each block, any movement made and information concerning it will be displayed.<\/span><\/p>\n

2. The blocks are connected to each other<\/span><\/h3>\n

In effect, each block of information (in which each transaction is located) is connected to the block before and the block after it; <\/span>forming a data string.<\/b><\/p>\n

Furthermore, these blocks are joined together in a completely secure manner, in order to prevent tampering.<\/span><\/p>\n

3 An irreversible chain or blockchain<\/span><\/h3>\n

Each block checks the previous block, creating <\/span>an unbreakable chain of data<\/b>a blockchain.\u00a0<\/span><\/h4>\n

This prevents anyone from tampering with the chain and creates a ledger in which the information is distributed among the different blocks.<\/span><\/p>\n

Types of blockchain<\/span><\/h2>\n

Depending on the type of blockchain network, we can basically distinguish 3 types:<\/span><\/p>\n
