Building Decentralization

I talked earlier this week on some of the current problems in decentralization at the rc3 event. It’s easy to be pessimistic about the current silo’d technological landscape, but decentralized platforms are continuing to make progress and there’s reason to be hopeful. At the same time, there’s a green field of many more decentralized protocols… Continue reading Building Decentralization


I’ve started to dive once again into the mess of connection establishment. Network address translation (NAT) is a reality today for most Internet users, and poses a significant hurdle in creating the user-user (or peer-peer) connections. NAT is the process used by your router to provide multiple internal (192.168.x.x) addresses that are all only visible… Continue reading Stunning


A quick screenshot of what I’m doing for my distributed computing final project. I’m calling it friend.s for now, although I’m not totally satisfied with that name. It’s a cross-platform piece of software that brings elements of peer-to-peer communication into your web browser. The goal is to be able to eventually offer a completely decentralized… Continue reading proxy2p

Distributed Computing so far

I gave a half-hour presentation on my research at the admitted students weekend earlier.  I think I was able to convey some sense of the opportunities that Mudd offers for research, and presented a reasonable face of what it could look like. The talk was an explanation of the concepts behind distributed hash tables, and… Continue reading Distributed Computing so far

Experimenting with 802.11s

The purpose of this document is an explanation of what is defined in the IEEE 802.11s standard, and the states of current implementations based on this standard. 802.11s is the standardization of mesh networking. That is to say that it defines a protocol for mobile devices where they can communicate amongst themselves even when not directly connected, and can route data beyond their immediate environment.

Torrent Auditor

I have now migrated the python torrent client that I’ve been working on to a google code project. It lives at torrentauditor and now has basic support for actually downloading torrent files. I researched the bittorrent extension protocols this week, but was somewhat frustrated by what I found. Most of the interesting ones are implemented… Continue reading Torrent Auditor

Auditing Bit torrent

One of the strengths of bit torrent is that the primary data transfer protocol is entirely separate from the advertisement protocol. This also has created a strain both in discovering other users who have data, and keeping accurate reports of data that was transfered. The first issue is one that has been developed for extensively,… Continue reading Auditing Bit torrent
