redecentralization 2.0

It has been a core thee of a lot of my work & interests. decentralized systems are just more interesting than centralized ones. they may be inherently more resilient (but not always), and they may be more complex (but not always).

the internet is largely decentralized in its lower layers (the tubes - the routers and links, and routing algorithms). that was always intended, from baran's report for rand onwards.
society and eco-systems are often decentralized (sure there are governments (but more than 1) and bee hives (but more than one) - but coordination happens peer-to-peer (a term which first arose in magna carta, but an idea which predates that by a billion years).

decentralized, infrastructureless networks are an interesting point in the design space - hence community mesh wireless networks, and opportunistic, delay and disruption tolerant networks work merely using users' devices and construct communication out of thin air. in this extreme environment, we are challenged to think of how we provide information about identity or trustworthiness, but in fact, on close examination, a central provision of those properties has many problems too - DNS certificates can be bogus or expired, source IP addresses do not have to refer to where the packet came from, an application layer user identifier (email address, facebook identity etc) is no more a true name than the Prince of Serendip.

so really, everything should be decentralized, as it forces us to confront the true problems and come up with decent solutions, instead of using the prop of underserved respectability of a centre.

That's why we founding the centre for redecentralization. :-)
