Re: [decentralization] The decline of P2P and Decentralisation
- Decentralized systems are much harder to design. ("costs more in time and money to get to equivalent features")Decentralized systems are much harder to debug. (where would you even attach an event logger?)Decentralized systems are much harder to deploy. (download vs. enter-url-in-browser)Decentralized systems are much harder to maintain. (compare upgrading a web app to a network of P2P nodes)Of course, they have many advantages that centralized designs cannot (ever) hope to match. But for the time being, the tradeoff between P2P-style systems on PC-class devices and centralized web sites is clearly won by the latter for the vast majority of applications.I'd suggest we need to look for areas other than PC-class P2P where centralized approaches cannot work and decentralized approaches are the only thing that might ever work. Such as:- systems that have intermittent connectivity and where the user won't tolerate to wait until connectivity is back- systems where all information cannot be stored in the same place (e.g. for security reasons)- systems whose components are produced and deployed by independent parties that won't (for example, for business reasons) ever agree on a centralized architectureFor example, the "digital living room", in my view, has no chance of ever coming into being unless the devices in it essentially form a decentralized network. The alternative would be that Big Dominant Vendor X "forced" every consumer electronics company into becoming a "client" to their "server", without which nothing would work. I believe that Big Dominant Vendor X does not currently exist, and probably won't exist. Ergo: it needs to be decentralized.There are other examples.Note that the devices coming together into one decentralized network are all different. (not all PCs, for example) I somehow think that this is a core feature of these types of decentralized networks.On a related note: OpenID, which is a truly decentralized system, is showing quite some growth these days, although it is server-to-server P2P rather than PC-class P2P.On Apr 23, 2007, at 11:37, Julian Bond wrote:
- The two places where we can promote P2P as a design pattern right now
is in the WHAT-WG of the W3C and the IETF. The WHAT-WG is the working
group responsible for defining the HTML5 standard.
Just last week I posted the following idea to the group's list and I'm
trying to recruit people that can help us explore this idea:
Keep in mind that for some reason my mail-agent and my friend's mail
agent broke the thread and it is separated into more than one thread
at the moment.
Gleicon has a few ideas for implementing this and I've gotten some
tips from others like Todd over at HighScalability.
If anyone on this list wants to participate or can indicate others to
participate, that would be awesome. Right now I'm trying to call the
attention of those with the technical knowledge necessary to take this
forward. I'm a product manager with the skills to help organize this
idea, but I don't know enough to make this happen alone.
