There has been a fair amount of effort on UCAN (User Controlled Authorization Networks), and other types of ‘decentralized credentials’ over the last couple years. These efforts perpetuate the same control structures that exist today, with delegated trees of hierarchical control. This is in contrast to a personal or ‘decentralized’ trust we might hope for… Continue reading On Trust

Retrieval Constraints
A couple months ago I wrote up some of the edges that I’ve encountered in thinking about how to structure decentralized data transfer systems. These are an extension of the limitations that were initially encountered in bittorrent style tit-for-tat exchanges, and have now matured into a much more extensive field looking at incentives and other… Continue reading Retrieval Constraints
Private Retrieval
It’s very exciting to have a public face to the thoughts around how to enable effective private access to data. Research Announcement The basic hypothesis here is that there’s a high-leverage opportunity to attract thought around scaling the range of anonymous database or data transfer techniques to reach something with better properties that the systems… Continue reading Private Retrieval

The TL;DR for me is that many of the trade-offs are… Continue reading What's Left for private Messaging

Over the course of my phd studies, there was a significant arc of time where the community yielded to caution as the issues around ethics were better understood.… Continue reading Ethics of Censorship Measurement
Corporate Censorship
One of the most interesting lines of inquiry within the Censored Planet project at the University of Michigan is trying to pull apart the different actors involved in Internet censorship. One of the interesting quirks is that a significant factor in why content might not be available to users is that the web publisher themselves… Continue reading Corporate Censorship
HOPE
I’m excited to see a bunch of friends next week at HOPE, an annual New York conference in the same vein as CCC. I’ll be participating in a panel on Internet Censorship on Friday morning, with a fantastic group of co-panelists. The talk recording is available here.

Open Letter to the Cuba Internet Task Force
The following is a response to an invitation to participate in the recently formed Cuba Internet Task Force. Task Force Representatives: I will not be joining the Cuba Internet Task Force, or Subcommittees, because I believe the harm done by the existence of these committees outweighs any potential benefit of the recommendations that can come… Continue reading Open Letter to the Cuba Internet Task Force
