Blockchain: security and transparency at the service of banking
The blockchain is a new reality that promises to change forever the way we manage our 
information in the digital world. 
This technology allows data and capital to be transferred in a completely secure manner 
thanks to sophisticated coding and encryption.                                 
You may have heard this term and still don't know what it means or the impact it could have on 
your life. As happened with the incursion of the Internet, the blockchain development could 
change our way of relating to each other in the digital world of banking, favoring, among other 
aspects, transactions, security or the management of the online entity.

. In addition, it allows a reduction in the necessary bureaucracy in financial operations and 
improves transparency.
The blockchain or 'chain of blocks' is a technology that allows the creation of networks of 
devices without the need for a central and localized server to connect them to each other. 
In order for these movements to be registered, they must have been approved by the rest of 
the participants in the 'block' network, that is, the users of this technology. And, once the 
information is entered in them, it can no longer be deleted, only new records can be added.
A fast and fraud-free payment alternative
One of the advantages of this tool is providing the possibility of making economic transactions 
quickly and safely against possible fraud and manipulation, since it uses encryption and 
coding. 
Another great benefit that it offers is the possibility of implementing a completely transparent 
business system in which we can all see the status of the accounts registered in "this great 
book", that is, what goes in and what goes out, in real time and with a low cost.
But the blockchain does not only work to carry out economic transactions. With this 
technology, important company documents and information can be stored and transferred 
without the possibility of someone accessing it without your consent. And what is most 
important: without the danger of it being modified. To guarantee the security and transparency 
of voting, at Santander we use this technology to vote at our General Shareholders' Meeting.
We invest in security and transparency
Aware of the impact that blockchain can have on the financial world, we have launched the first 
bond with end-to-end blockchain technology, which is a first step for a possible secondary 
market for tokenized securities in the future. The $20 million bond will remain on the 
blockchain for its entire life, until maturity.
For the issuance of this bond, we have used the public Ethereum blockchain, one of the most 
advanced open source blockchain technologies. This has allowed us to securely tokenize the 
bond and record it in a permissioned manner on the blockchain .
 More and more people and companies are entrusting their data to this technology for the 
reasons already mentioned. Blockchain becoming a daily reality is something that could 
happen very soon and we, committed to innovation, want to contribute to a technology that 
helps create a more open, connected and transparent society for citizens.
