What is Blockchain?

The Blockchain is a technology based on a decentralized and public blockchain of operations. This technology generates a shared database to which its participants have access, which can track each transaction they have made. The programmable and open nature of this technology allows innovating the financial sector and administrative processes to make them more efficient and transparent. In addition, the bureaucracy is reduced. The Blockchain is the technology that developed the Bitcoin , the virtual and intangible cryptocurrency that is sustained by the protocol and the P2P network.

To make it easier, we can compare Blockchain technology with a large ledger in which all transactions are recorded, with the addition that the data cannot be manipulated and, in addition, they are verifiable.

The main advantages of this new technology is that transactions can be stored safely and verified without the need for third parties (intermediaries).

Another reason for being is to reduce fraud in operations. All participants have access to transactions and a consensus of all is needed to modify them. This builds trust in business , something that until now has been difficult to achieve online. In addition, as it is a public operations blockchain, the security of transactions is protected since all people have access to a single source of shared trust.

One of the facilities that Blockchain provides is to be able to carry out an economic transaction from Spain to any country in a time of between five and ten minutes. But it can also be applied, for example, to finance “stock” movements or sign smart contracts.


In short, with Blockchain, processes are streamlined and cheaper, transactions are more transparent and intermediaries are eliminated.

How does the Blockchain work?

The blockchain is a record of all transactions, stored and shared publicly. The so-called miners are in charge of verifying these transactions. After that, they are included in the chain and distributed to the nodes that make up the network.

Let’s see what each of these elements consists of:

1 #  Blocks. A block is made up of a set of transactions. Each one is part of the blockchain. The Bit2me company , specialized in Bitcoin and its technology, defines each of the parts that make up a block:  

  • An alphanumeric code that links to the previous block.
  • The “package” of transactions it includes (the number of which is determined by different factors).
  • Another alphanumeric code that will link to the next block.

The next block in progress is trying to find out with calculations the alphanumeric code that allowed the previous block to link to it.

2 #  Miners. Miners are computers / chips that are in charge of verifying all transactions. When someone completes a block or makes a transaction, they receive a reward in the form of Bitcoins.


3 #  Nodes. A node is a computer / chip that is connected to the Bitcoin network. It is dedicated to storing and distributing an updated copy of the blockchain. Therefore, each new block that is committed is added to the blockchain and to the copy that each node stores.

Banks are betting on Blockchain technology

This technology is already being applied in many sectors, but it is currently being exploited by the banks. Several studies at the time assured that 15% of banks and 14% of financial institutions contemplate introducing Blockchain solutions and technologies in 2017.  And it is expected that in 2020, 20% of global companies will integrate this technology . In reality, what banks are seeking is to implement technologies to eliminate intermediaries and distrust in transactions.

BBVA, Bankinter or Banco Santander are some of the large banks that have detected an important source of investment in Blockchain technology. They are starting to install this system in their transactions, with the aim of improving process security and eliminating the costs of traditional transactions.

The Blockchain reaches SMEs

Small and medium-sized companies represent about 75% of the total number of companies that make up the Spanish economy, according to data from the ePyme Report 2015: sector analysis of the implementation of ICT in Spanish companies . This data shows that SMEs are a fundamental pillar of the financial industry in our country, so that all the technological innovations they develop will have a key impact on the current economic model.

The Thermometer report of the middle market in Spain reveals that 85% of entrepreneurs say that the turnover of their companies will increase and only 2% believe that sales will fall. This happens, among other factors, because SMEs have detected the need to go through a process of digital transformation and, therefore, to investigate ways to open new business models adapted to the digital age.


Some startups are leading the introduction of Blockchain technology. They use it as a method to decentralize and allow users to control their own movements, without the need for the intervention of third parties.

For example, Storj is a startup that has developed a beta version of a service that allows creating a decentralized database , using Blockchain technology, to increase security. To understand it, it would be like cloud storage services, such as Dropbox or Google Drive, but, unlike them, in this case there is no single provider that is responsible for the data that is stored.

Another of the possibilities offered by Blockchain is the creation of Smart Contracts . It consists of automating the processes of a business (payments, suppliers, supply…) through a virtual machine that stores and manages the information. The machine becomes the person who talks to vendors and makes payments. The Spanish startup Clluc creates platforms for companies to have access to these Smart Contracts .

Do you want to specialize in Blockchain?

As we can see, the development of Blockchain technology is still in an embryonic phase. But more and more companies detect its potential and the opportunity to welcome new business models, in a new financial environment.

Do you want to specialize in Blockchain? Get it with our Master in Blockchain and Fintech , and from the hand of experts such as Javier Martín , Director of Open Innovation at Sngular, Alejandro Guasch , Project Manager at SEAT, among many others, who will give you the necessary keys to understand how it works new technology and how to apply it within a company.

  1. When you have entered the crypto you chose, you will see a Buy – Sell panel.

Ways to trade cryptocurrencies in

In this buy-sell panel or trading box, you will have some options that will allow you to perform these operations:

Steps to buy cryptocurrencies within Skrill

First of all, talking about the purchase of cryptocurrencies in the Instant mode (which is the usual one), you will be able to do the following:

Steps to Sell Cryptocurrencies within Skrill

  • The Watchlist, with which you can keep abreast of the indices of your cryptos in the market.

  • Alerts and orders. With these options you are given the possibility to mark an index within the cryptocurrency, which, if the price reaches it, this will be notified to your email or mobile, as you have it configured.
