Interview as a Speaker for the European Blockchain Convention



European Blockchain ConventionInterview done as part of the Speaker Series for the European Blockchain Convention at Barcelona.













"Public blockchains really express the most powerful features of blockchains. Public blockchains often provide more transparency, better security, larger consensus and maximum levels of decentralization.

 

However public blockchains are difficult to monetize, they are difficult to adapt to comply with strict regulations and their performance are often suboptimal for special use cases.

 

This is where private blockchains come to life, while public blockchains will provide the underpinning infrastructure for most solutions".

Welcome to Speakers Series where we get closer to our Speakers

Victor Escudero is Global Head of Integration of Cybersecurity Solutions at S21sec and co-author of the book "Blockchain: the Industrial Revolution of the Internet"

Escudero is passionate about Free Software. He has lived and breathed Bitcoin since its inception and since then he actively shares his knowledge about protocols based on Blockchain.



1. Where were you the first time you heard the word Bitcoin?

 

I was leaving the office after work when I received a phone call from an old friend. He told me that he was amazed after seeing that someone had invented a system to make new money based on an open source license. It was back in 2009 and I didn’t spend a minute to check the new invention. Several weeks after that, another friend that was an amateur trader in Australia told me something about a cheaper way to exchange fiat money from one currency to another via a new digital currency. After that second chance, I decided to take a look on the Internet, but after a quick search I did not find any reference to Bitcoin. Fortunately, a few days later a colleague of mine that was also researching about new applications of Elliptic-curve cryptography pointed me to an article that had a reference to Bitcoin’s white paper. After reading Satoshi’s white paper and for the next six months, I couldn’t stop reading avidly everything I found about bitcoin.


2. Does Blockchain offer hype or hope?


Hope. There has been too much hype around blockchain in the past and it continues even nowadays. One of the reasons of that hype is that one of the first use cases of a lot of blockchains has been related to the transfer of money and, especially, to the financing of new companies through ICOs. However as more and more uses cases continue to emerge every day, blockchain will keep on providing excellent responses to new needs.


3. Have you ever used a Blockchain or a DLT? If yes, for what?


Yes. I began using the old Ripple system (the one that was born in 2004, way before Bitcoin) to exchange time credits between open source communities in the past. Regarding Blockchain I have used dozens of cryptocurrencies and done operational research of new applications in the cybersecurity area.


4. Do you think Blockchain in the future will be as important as the internet is today?


I think the Internet and Blockchain are different kinds of animals. Internet represents interconnectivity in such a large scale that its impact goes beyond any other technology humankind has developed after the invention of the wheel and the discovery of fire. Blockchain is a disruptive technology that will impact our future as much as other disruptive technologies like Artificial Intelligence, 3D printing or Robotic Process Automation will do in a few years. However Internet will keep on being the enabler for most of the advances we will see in the near future. In essence, Blockchain provides distributed trust and as such, it relies on the underlying connectivity of its nodes, often through the internet.


5. Public Blockchains or Private Blockchains?


Both of them, but for very different purposes. Public blockchains really express the most powerful features of blockchains. Public blockchains often provide more transparency, better security, larger consensus and maximum levels of decentralization. However public blockchains are difficult to monetize, they are difficult to adapt to comply with strict regulations and their performance are often suboptimal for special use cases. This is where private blockchains come to life, while public blockchains will provide the underpinning infrastructure for most solutions.

VEscudero en el Telediario de TVE: Goldman Sachs operará con bitcoins

Intervención en el Telediario de La 1 de Televisión Española con motivo del anuncio de Goldman Sachs de crear una mesa de negociación de futuros sobre bitcoin para prestar el servicio de brokerage a inversores institucionales.

Por el momento la firma de inversión estadounidense ha decidido no comprar y vender bitcoins directamente, sino que en su lugar realizará compras y ventas de futuros en el mercado de Chicago en nombre de sus clientes.

De esta forma Goldman atiende la enorme demanda que estaba teniendo por parte de grandes inversores institucionales de empezar a cubrir el mercado de bitcoin, pues éste es visto como un activo de inversión cuyo riesgo está altamente descorrelacionado de otros activos y con un gran potencial como reserva de valor y/o valor refugio.

El video fue grabado el día 4 de mayo 2018 en las instalaciones de S21sec, la empresa de ciberseguridad en la que trabajo como Global Head of Integration, es decir responsable del área que realiza la implantación de productos y soluciones de ciberseguridad para los clientes de la compañía.

Colaboración en artículo sobre Petro en la sección de Internacional del diario ABC

Colaboración con el diario ABC, sección Internacional
Colaboración con el diario ABC a razón de la próxima oferta pública de venta que el gobierno venezolano realizará a través de una nueva criptomoneda.

A finales del 2017, el gobierno de Nicolás Maduro decidió crear una nueva moneda denominada Petro, cuyo valor estará respaldado por las reservas petroleras de la República Bolivariana de Venezuela.

El Petro será la primera criptomoneda respaldada oficialmente por un estado y su implantación supondrá un reto de enormes dimensiones, de ahí la gran atención que está suscitando su inminente  lanzamiento.

Técnicamente, la ICO (Initial Coin Offering) presenta algunos inconvenientes para los inversores: ha sido parcialmente preminada, más de la mitad de la recaudación irá directamente a un fondo soberano controlado por el gobierno de Maduro, su desarrollo está bajo el control de un reducido grupo de desarrolladores (no identificados), el algoritmo de prueba de esfuerzo (PoW, Proof of Work) podría ser sustituido en un futuro por una prueba de tenencia (PoS, Proof of Stake), no hay prevista ningún tipo de limitación que impida al gobierno de Maduro poder emitir a voluntad más monedas de las inicialmente previstas, así como manipular el precio de sus propias reservas petroleras y especular abiertamente sobre el precio de su propia criptomoneda, gracias al control que puede ejercer sobre la información sobre sus reservas petroleras y el control de los Exchanges donde estará permitido intercambiar los Petros.
