https://blockchainespana.com/meetup-debate-blockchain-vs-dlt-distributed-ledger-technology/ 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. Jesús Pérez Director de Digital Asset Institute, Gestor de Tokenomics Stars Crypto Fund en Iconomi , Director de Fintech Ventures, Socio de Finnovating, Miembro del Instituto Español de Analistas Financieros, CFTE, Fundador de Sersan Sistemas y Accurate Quant. Fundador de AEFI (Asociacion Española de Fintech & Insurtech).

Need of digital currency native to the Blockchain
• Native to the Blockchain: digital, programmable and
moving “at the speed of Blockchain”
• Price stability, so it can be used as an efficient Medium
of Exchange
• Price transparency: less currencies better than more
• Universally accepted and highly liquid, especially with
regards to fiat currency
• Consumer protection: maintain or enhance current
consumer protection system
• Legally compatible
