In this episode, returning guest Abhistha -- now Assistant Professor in network security at the University of Utwente -- digs into his latest research on the real economic impact of distributed denial-of-service (DDOS) attacks such as the Mirai botnet. With the internet-of-things continuing to grow as an attack surface, and compromised devices increasing both in number and processing capacity, we take an in-depth look at the underground economics of botnets -- and why some large corporations may not be owning up to the true extent of the threat to their bottom line.


In this episode, we meet Rich Myers of mesh networking company GoTenna. Rich is developing the Lot49 protocol, which both allows Lightning transactions over a local mesh network and uses Bitcoin incentives to increase the adoption of the network. Rich and I discuss the history of wireless networking and how P2P meshes could turn out to be critical in a time of crisis; why and to what extent we can consider our contemporary networks compromised through what Rich calls 'The Eye of Sauron' problem; and how Lot49 enables an internet-minimized micropayments solution which could function in a distressed, post-COVID environment.


In this episode, I talk to Sean Moss Pultz, CEO of Bitmark Inc. -- a company focused on enabling personal data sovereignty through blockchain technology. We discuss Bitmark's journey and the company's latest pivot to Spring, an app that helps users extract personal data from Facebook and put it to work in all kinds of interesting ways.

We discuss Seans's thoughts on data sovereignty and data rights as critical civics issues and look in detail at how Spring can empower a new level of control over your personal data, providing a much-needed counterweight to big platforms who regard your information as their intellectual property.

During these uncertain times, I'd love to connect with listeners more than ever. For that reason I'm temporarily opening the Patreon discord to anyone who wants to join -- just email me at [email protected] and I'll send you an invite. At times like this, we all benefit from exchanging information and ideas about what we should be doing and how to survive whatever comes next.
