In 2019 the internet celebrates a triple anniversary: 50 years of the first computer-to-computer connection, 30 years of WWW creation, and 20 years of Napster. Three milestones to celebrate and reflect on the next 30 years of the web, where decentralization protocols will play a capital role. Sonar+D 2019 invites researchers, journalists and activists to imagine the future of the web; a future that it is open, free and sustainable.

For this we will count on the presence of the cybersecurity journalist Marta Peirano, who is about to publish her book "El enemigo conoce el sistema" (The Enemy Knows the System); the researcher and activist Xenia Ermoshina, and the "solarpunk" theorist Jay Springett.
