Presentación debate Blockchain vs DLT Jesús Ruíz


Published on
El concepto de Blockchain surge con el lanzamiento de la red Bitcoin el 3 de enero de 2009 aunque en el mundo de las blockchain públicas no existe todavía un consenso sobre lo que quiere decir Blockchain. Pero tampoco lo hay en el mundo del Distributed Ledger Technology (DLT), llamado a veces blockchains privadas.

En este meetup abordaremos los diferentes puntos de vista existentes sobre el significado de Blockchain y DLT, desde un punto de vista técnico y de la percepción que existe en la opinón pública del término Blockchain
y DLT. Para este debate hemos invitado a Jesús Ruíz, CTO de Alastria, y Jesús Pérez, Fundador de Crypto Plaza.

Jesús Ruíz
CTO Alastria y Co-Convenor del Technical Working Group del EBSI (European Blockchain Services Infrastructure). Previamente líder de la práctica de Blockchain e Industria 4.0 en el Banco Santander.
