Few questions;

1) what sort of articles? (e.g. broadly technical, detailed technical, political, economic, legal, financial, etc)

2) how much?

3) will you pay in bitcoins?  Smiley

Interesting strategy, quite machiavellian too. Introduce bitcoin as a friendly, cuddly alternative to government scrip, the new-fangled "money through the inter-tubes for the future" thingy .... quite harmless really.

... net result a trojan, I like it. Phone those congress critters up and tell them all about it. Smile sweetly as you dream of the day their pay will be denominated in BTC.

While were in development stage lets solve some more problems, like the removal of ssl certificate authority! How about when you register a domain you get a private and a public key for it, then when you go to a website you browser asks namecoin for the public key for that domain, and then a secure connection is established. This system can be implemented into the existing ssl standard. What do you guys think?

Very interesting idea ... I'm listening. Sounds almost too simple (i.e.too good to be true) could be brilliant. Flesh it out some more.

Would greatly increase potential benefits of namecoins if we could do away with those lecherous certificate "authorities
I just stumbled on to namecoin and I am shocked it does not work this way already!  You own the domain via private key, logic would dictate you would not need ssl certs.

Hmmm ... looks like you maybe able to do TLS using a ECDH_ECDSA (or ECDHE_ECDSA) scheme with the namecoin secp256k1 private key ...

ironically ".... The NamedCurve name space is maintained by IANA...." (secp256k1 is a "NamedCurve", amongst many others)

How much? and how soon?

Price and availability? ...  Smiley

Someone has to draw the thing first! I will put my current (1FPGA) board up soonish for someone to convert to the desired board.

Yeah, I know that .... Just trying to make you aware that there are other considerations for a successful piece of kit (any product) besides the technical solution.

Edit: oops, see that you're already doing this ... butting out now.

Saying that I'd probably be in the market just for the interest aspect. What software is freely available and/or supplied?

I also wonder if all communications could not be done using HTTP.  Blocks would be published via http GET method (giving the hash of the preceding block), and transactions could be sent via POST method.

One advantage of using http would be that it would be very hard for governments to forbid.

Where did you get to with the network connection side of this, netcat could be an option.

How much power will you be pulling through the DIMM bus with this?

For the biggest Xilinx Spartan 6 and 80% efficiency:

(1.2V * 5A + 2.5V * (1.6A + 0.3A)) / 12V / 0.8 = 1.12A

For 4FPGAs this would be 4.5A, let's say 5A.

And how many cards on single mobo are you thinking?

I have no clue what O_Shovah thought. Maybe 8 or 16?

So 5x16=80A on mobo DIMM bus power rails is no problem?
7291  Bitcoin / Development & Technical Discussion / Re: Does Namecoin solve the backing problem? on: June 28, 2011, 08:33:51 AM

So what about using namecoin blockchain to record land/property title deed ownership?

The recent rush to centralise property/land ownership records in databases and obsolete land deed titles makes me nervous. (It's like pulling teeth if you ask the lawyer to see the actual title these days)

Not to mention avoiding all the shennigans that went during the mortgage debt boom, CDO's etc.
7292  Bitcoin / Development & Technical Discussion / Re: Modular FPGA Miner Hardware Design Development on: June 28, 2011, 08:27:32 AM
What about something like this (klick on image to see full size):



The board is 45mm high and has 4 FPGAs (Xilinx XC6SLX150 in the smallest package). The components are all on one side, but I probably left too little room for the auxiliary components of the switchers (see my previous post on them: LM3150, 3x LM21215A-1). As you can see, I cannot make the Molex connector fit.

Comments?

7293  Bitcoin / Development & Technical Discussion / Insecure local private keys problem definition (and brainstorming) on: June 28, 2011, 05:22:57 AM
If I'm understanding this correctly, the philosophy behind the bitcoin network protocol has been to concentrate the effort in securing network comms. (transaction sends, block transmission, etc) and securing the block chain record (hashing) but leave securing the client nodes private keys up to the end users. However, I think this overlooks the fact that for the send tx. to occur the client has to move around the unencrypted private keys on network connected hardware.

In this sense, we can consider the network connected hardware of the clients to be part of the network and maybe should be treating it as such. The alternative is to tend towards a two-tiered system where web-wallets, exchanges, merchants, etc who need to have clients connected 24/7 will bear the brunt of maintaining network stability, operating with 'live' wallets, while a majority of users who will only briefly connect clients intermittently. Obviously, this will lead towards a more centralised client-server relationship that seems to go counter to the ethos of the project.

The problem then:

unencrypted private keys must reside and move around on the client's network connected hardware, at some point, for signing of the send transactions to occur and thus any network connected hardware forms part of the bitcoin network at that point in time.

In this light, perhaps solutions to consider could involve encrypting the private keys with the same strength of the signing of the send tx themselves (ECDSA) operating under the assumption that the clients machines, PC's, servers, etc, are essentially part of the untrusted network layer. As a brainstorm, is it possible to come up with a cryptological scheme whereby the private keys never need be decrypted on the client machine yet can still perform the signing?

Anything else will probably lead to a situation where the long term stable network effectively ends at those nodes that are capable of securing private keys on network connected hardware. Possibly limiting widespread adoption.

I've dug into this subject. In the name of forced gender equality, Nordic countries are employing nearly all working age females in state-run jobs that do not necessarily produce anything of value, but full salaries are paid out from taxes  (= people who do real work in private businesses)

Nothing scarier than blondes who earn the same as you ....

Dollar seen losing global reserve status
By Jack Farchy in London

The US dollar will lose its status as the global reserve currency over the next 25 years, according to a survey of central bank reserve managers who collectively control more than $8,000bn.

More than half the managers, who were polled by UBS, predicted that the dollar would be replaced by a portfolio of currencies within the next 25 years.

Now let's see ... $8,000 bn divided by 21 million comes to ??.... wait a minute!
7298  Economy / Economics / Re: Namecoin prices plummeting - opinions? on: June 28, 2011, 01:19:15 AM
Namecoin is essentially filling a need that does not yet exist.  The US gov't has been meddling with the internet more and more and wants to control whatever they can.
But to look at it another way, the benefit of dns seizure immunity doesn't necessarily have to be a key selling point in order for there to be an appeal for namecoin domains. The internet as seen from Google becomes progressively stupider over time, overflowing with SEO fluff and populated by high schoolers testing out their arguing skills. There can be a certain appeal to a site/server being a little out of the way, even if doesn't relate to anything remotely illegal or controversial.

This is real ... exclusivity through obscurity. Hard to find corners of the net are now .... well hard to find, not like the good old days ... out of site of the googly-eyed all-seeing monster is nice.
7299  Economy / Economics / Re: Namecoin prices plummeting - opinions? on: June 27, 2011, 11:54:53 PM

Wondering when Silk Road will start accepting Namecoins as well as Bitcoins?   A extra layer of abstraction wouldn't hurt ... how hard would it be to trace something simultaneously through btc and nmc blockchains back and forward like?
