Harry Halpin is a privacy lover and freedom advocate who embarked on an ambitious journey to create a better Tor, which is actually decentralized and provides incentives. The name of his project is Nym & it makes use of mixnets to prevent traffic analysis.

In this episode, Harry Halpin talks about the meaning and scope of privacy in the digital age, why the Nym project accepted a financial grant from the European Commission, why Nym provides better data anonymization than Tor, and how several cypherpunk ideas get rediscovered years later in order to fix contemporary problems.
