The GDPR and Data Protection in the Decentralized Web

How do we think the GDPR and data protection rules are most likely to apply to the decentralized web? How can developers either comply with those rules or design their systems in line with the underlying goals of protecting privacy and giving users control over their data?
This roundtable provides an opportunity for developers who care about the privacy goals underlying the GDPR to learn from legal experts, to share information about their systems and how they view compliance, and to hear from engineers with implementation experience.

Matthew Hodgson
Technical Lead, Matrix

Matthew Hodgson is technical co-founder of a not-for-profit open source project focused on solving the problem of fragmentation in current Chat, VoIP and IoT technologies. By defining a new lightweight pragmatic open standard for federation/interoperability and releasing open source reference implementations, Matrix hopes to create a new ecosystem that makes open real-time-communication as universal and interoperable as email.

Matthew juggles Matrix with the roles of CEO and CTO of New Vector, the company behind, the flagship collaboration app built on Matrix. Previously, as a technical lead at MX Telecom (acquired by Amdocs in 2010), Matthew designed & architected Amdocs’ next-generation Video/VoIP client and network infrastructure, and draws on his Internet background to rapidly deliver carrier-grade enhanced communication solutions to network operators.

He has a BA in Computer Science and Physics from the University of Cambridge, and has lectured on VoIP at Imperial College London.

Matthew believes in the virtues of open collaboration. We live in an era where we can benefit very easily from cross-industry inputs to foster innovation and we don't make enough out of it. He wants to change the world to give access to communication and privacy to everyone while keeping the user's experience at the heart of every new product and leaving everyone the choice of their provider.
