Mike, you're a rock star. Great work. It's strange they framed you as 'the man in the cloud' or whatever you'd call the scratchy effect. But the apple pie living room background was an excellent touch. I wonder how they'd frame some eskimo on a whale hunt trading bitcoins over a sat link. Smiley

The Casascius 1oz 10BTC Silver Round (w/ Gold B)
November 10, 2011, 11:43:41 PM
CBS news station KOLD in Tucson Arizona is currently showing a video commercial for an upcoming TV story about Bitcoin that will air at their 10:00 news which starts about 20 minutes from now (10:00 PM Arizona time, 0500 UTC).  The video commercial is now visible on their website, as well as a prominent advertising blurb on the station's home page.

It appears there is a link on the home page that allows live watching of the newscast.

Revolutionizing Brokerage of Personal Data

That chart likely wouldn't record my own 'shy' client, and I'm sure that there are more than just mine.
True and there are a number of other reasons why this number might go down - for example mining got more centralized due to lower profitability, people regaining confidence in webwallets, etc.

From a network security point of view in the spirit of the cited paper the reasons are however pretty much irrelevant. I don't think we have to worry yet, but it is arguably easier to do certain kinds of attacks with fewer nodes listening for connections.

Anyway, we probably should take this discussion some thread else.

The number of nodes is declining steadily.

What do you base this statement upon?

Maybe graphs like this: http://bitcoinstatus.rowit.co.uk/ ?

Miners have a tit-for-tat incentive to propagate transactions to each other as quickly and reliably as possible. They might also have an incentive to collude. There is little incentive for an end-user to propagate transactions ('better for the whole') nor for miners to propagate to end-users, except that the costs of doing so are negligible compared to the discovery benefits. I'm cool with an ad-hoc central core of miners. With lower latency and higher reliability, the block rate could theoretically be lowered (faster confirmations), though other solutions such as green addresses or side channel credit transactions should be acceptable enough and instantaneous.

On Bitcoin and Red Balloons

https://sites.google.com/site/dobzin/papers/bitcoin.pdf?attredirects=0

Abstract
We study scenarios in which the goal is to ensure that some information will propagate through
a large network of nodes. In these scenarios all nodes that are aware of the information compete for
the same prize, and thus have an incentive not to propagate information. One example for such a
scenario is the 2009 DARPA Network Challenge (finding red balloons). We give special attention to
a second domain, Bitcoin, a decentralized electronic currency system.
Bitcoin, which has been getting a large amount of public attention over the last year, represents
a radical new approach to monetary systems which has appeared in policy discussions and in the
popular press [3, 11]. Its cryptographic fundamentals have largely held up even as its usage has
become increasingly widespread. We find, however, that it exhibits a fundamental problem of a
di®erent nature, based on how its incentives are structured. We propose a modification to the
protocol that can fix this problem.
Bitcoin relies on a peer-to-peer network to track transactions that are performed with the currency.
For this purpose, every transaction a node learns about should be transmitted to its neighbors in the
network. As the protocol is currently defined and implemented, it does not provide an incentive for
nodes to broadcast transactions they are aware of. In fact, it provides a strong incentive not to do
so. Our solution is to augment the protocol with a scheme that rewards information propagation.
We show that our proposed scheme succeeds in setting the correct incentives, that it is Sybil-proof,
and that it requires only a small payment overhead, all this is achieved with iterated elimination
of dominated strategies. We provide lower bounds on the overhead that is required to implement
schemes with the stronger solution concept of Dominant Strategies, indicating that such schemes
might be impractical.


Gavin have talked about the incentive of relaying transactions, maybe someone have the solutions?

 "Each node on the path in the tree from the seed to the authorizer appears on this
chain..."

yeah i get the point, some individuals realized they can't possibly trace transactions to their origin and now they try with social engineering schemes. Honest ppl will relay traffic regardless of their personal gain so they add value to the system, just like running a tor node, by helping other peers be free. They just suppose all nodes are miners, in their calculations.
I think it's a small price to pay for all the advantages i get in exchange  Cheesy

Includes a small Bitcoin mention. The article is more focused on how traditional banks could offer virtual currency services.

In 18 months, depending on how the global banking/economic crisis plays out, the industry "may start to see the tip of the iceberg emerging" with banks offering virtual currency services, Newton says. "There's not going to be an overnight changing of the markets."

Not a new article, but I havn't seen it before.  It's not about Bitcoin per se, but mentions it.

"We need a MAS model that is resilient before we start risking people’s precious funds. We’re wise to take hints from bitcoin, open source software projects, anarchism, leaderless resistance and the whole peer-to-peer concept (P2P) (egalitarianism). If funds and lists aren’t stored centrally, they can’t easily be seized. If there is no bureaucracy and no company president or board, they can’t be indicted or compromised. The key to a resilient MAS is that simple: decentralize."

The Motley Fool follows up from a previous story.

Quote
But what about the long-term prospects? In an email, Andresen relayed that he remains upbeat on Bitcoin's future. Furthermore, he mentioned "dozens" of development-stage projects, including secure "Bitcoin wallets" for cellphones. Although he doesn't see such ventures as critical to Bitcoin's success, they could, in my view, provide a notable boost.

This is not a pure bitcoin piece but it points a lot of peeps in the right direction  Grin

here's the blurb:

Quote
The much-maligned Bitcoin movement to create an anonymous, decentralized, digital currency free of the oversight of the world’s central banks can be best understood as a precursor to the Occupy movement. Now that Bitcoin has demonstrated itself as a proof-of-concept and the daily stress and strain of the Euro continues to attract international headlines, there are alternative currency concepts based on Bitcoin waiting to be implemented by tech entrepreneurs.
