hey, finally took the trouble to syndicate one of my Chinese blog content with my diary config... it looks like working great!

which is the more disappointing that this instance isn't working at the moment...

Japan’s new Bitcoin business advocacy group, The Japan Authority of Digital Asset, has launched with the government’s explicit support, aiming to help establish standards and codes of conduct for its member organizations. The group was formed by Japanese parliament member Mineyuki Fukuda and his IT Committee, after consulting with Japan’s Financial Services Authority and speaking with the country’s resident Bitcoin ATM companies and exchanges, which include digital currency exchange Kraken and its parent company Payward Inc.

Major music streaming service Grooveshark has started accepting Bitcoin for both their monthly and annual subscriptions, after receiving several requests from users to add the digital currency as a payment option. No official statement has yet been heard from the company, but several forum reports of the new payment option have begun surfacing from Grooveshark users in response to their requests.

Prominent porn video site xHamster, the 56th most popular website on the internet, has also reportedly started accepting Bitcoin as a payment option, which has sparked a slightly Not Safe For Work thread on the Bitcoin subreddit.

Bitcoin entrepreneur and nextcoin investor Androklis Polymenis is offering a 500 bitcoin bounty for the return of his lost 1170 bitcoin and 6 million nextcoin, which were stolen when a hacker posed as Polymenis on bitcoin exchange Bter.com and requested the removal of the funds.

EQUILIBRIUM POINTS IN N-PERSON GAMES

By John F. Nash, Jr. , Princeton Univ.

Communicated by S. Lefschetz, Nov. 16, 1949

One may define a concept of an n-person game in which each player

has a finite set of pure strategies and in which a definite set of payments

to n players corresponds to each n-tuple of pure strategies, one strategy

being taken for each player. For mixed strategies, which are probability

distributions over the pure strategies, the pay-off functions are the

expectations of the players, thus becoming polylinear forms in the

probabilities with which the various players play their various pure

strategies.

Any n-tuple of strategies, one for each player, may be regarded as a

point in the product space obtained by multiplying the- n strategy spaces

of the players. One:-such n-tuple counters another if the strategy of each

player in the countering n-tuple yields the highest obtainable expectation

for its player against, the n - 1 strategies of the other players in the

countered n-tuple. A self-countering n-tuple is called an equilibrium point.

The correspondence of each n-tuple with its set of countering n-tuples

gives a one-to-many mapping of the product space into itself. From the

definition of countering we-see that the set of countering points of a point

is convex. By using the continuity of the pay-off functions we see that the

graph of the mapping is closed. The closedness is equivalent to saying:

if Pi, P2, ... and Qi, Q2, .... Qn, ... are sequences of points in the product

space where Q. -n Q, P n P and Q,, counters P,, then Q counters P.

Since the graph is closed and since the-image of each point under the

mapping is convex, we infer from Kakutani's theorem' that the mapping

has a fixed point (i.e., point contained in its image). Hence there is an

equilibrium point.

In the two-person zero-sum case the "main theorem"2 and the existence

of, an equilibrium point are equivalent. In this case any two equilibrium

points lead to the-same expectations for the players, but this need not occur

in general.

* The author is indebted to Dr. David Gale for suggesting

the use of Kakutani's theorem to simplify the proof and to the A. E. C.

for financial support.
