This was a legit legal question yet you guys have derailed it into a childish discussion... amazing..

You should have put it up in the "Legal" section (along with the hundred other threads asking similar questions) ... instead you threw it into the mosh pit. Really, what did you expect?

Bitcoins are nothing ... yet they could be anything. Their ephemeral nature is going to be twisting lawyers, politicians and judges minds into pretzels for decades (that's one of the reasons I luv the tech.  Cheesy ).

First, you need to define what is a "bitcoin"?

Is it the private crypto key?, is it the blockchain ledger entry?, is it the software that looks up the database? or the software that can transfer value between keys?, is it the miners that secure the transactions entries? or etc? ... start there.

Quote
in this case instead of cost in hash power for clients, it costs in namecoins and the namecoin verification nodes(miners) are paid to keep "key integrity"

... this quote makes me think that you have got the crux of the idea.

Namecoin is already doing the job you require, i.e. keeping key integrity ... and since it is secured with merged mining by much of bitcoin network hashpower, it is possibly the most secure human-readable nameID linked key integrity system in the world waiting there to be taken advantage of ...

Web-of-trust is only weak protection against MITM (as is CA) versus using a namecoin ID authenticated public key for the key-sharing initiation of a connection.

http://en.wikipedia.org/wiki/Perfect_forward_secrecy

"OpenSSL supports perfect forward secrecy using elliptic curve Diffie-Hellman since version 1.0"

http://en.wikipedia.org/wiki/Key-agreement_protocol

"Protocols that are useful in practice also do not reveal to any eavesdropping party what key has been agreed upon."

perhaps namecoin does something that I'm not aware of as far as man in the middle attacks but im pretty sure that if i gave you my name coin address, an attacker(lets say a moderator in this example) could replace my namecoin address/id on the post, I don't understand how namecoin is solving this MITM issue (or perhaps I'm looking at the namecoin solution different then what is being presented)

I agree, I don't think you are understanding the use correctly ... it's a little involved and I'm not sure if I want to go through all the details here. You seem to be a clever guy so I'll just out line the scheme and you can probably fill in the details.

- Users secure their 'name' in the namecoin blockchain, (i.e. only they hold the namecoin private key associated with that name)
- Also users associate with that name an EC public key using one of the appropriate namespace facilities of namecoin
- When initiating a connection the Sender creates a shared secret using their EC priv. key and EC public key of Recipient by looking up namecoin blockchain (autonomously if need be)
- Receiver can verify who the Sender is securely (and autonomously if need be) by looking-up Sender's EC public key up on namecoin blockchain and creating the required shared secret to communicate initiate ack response
- Sender-Receiver use shared secret encrypted channel to exchange AES keys for encrypting primary dialogue
- ... and etc, do the ECDH as usual from here on ...

... could also do a pay-per-secure-connection model using the namecoins/bitcoins per data-byte ... e.g. sender sends namecoins to receiver address to initiate connection, receiver (streaming server) only allows paying senders to open secure connections ... and stuff like that, hope this helps.
6527  Bitcoin / Bitcoin Discussion / Re: GoldMoney [FB post]: James Turk in conversation with Félix Moreno de la Cova on: January 18, 2013, 02:22:49 AM
I don't get this whole thing.  Can't goldmoney be transfered from one goldmoney customer to an other goldmoney customer?  If so, it should be easy to exchange bitcoins into goldmoney in both ways, via any currency exchange service.  

So to me there should be no need for GoldMoney to deal with bitcoins in any way, as long as they provide internal liquidity for their customers.

It used to be like that, as I understand it I'm not a customer. BUT, recently they changed their terms due to recent law changes/uncertainties and now only GoldMoney customers domiciled in Jersey (i.e. tiny percentage) can still use the account transfer facility.

Bitcoins maybe a way to circumvent the new legal traps and give an inter-account transfer facility back to their global customer base I suppose, albeit they transfer/exchange between accounts using only Bitcoin but then hold balances in Bitcoin and/or GoldMoney holdings.

"Hauled" is not the right verb to be using in this context .... US fed can only deliver 50 tons per year for the next 7 years, basically is how long it takes to buy it off the mines I'd imagine.

More like a trickle and not even a majority of the holding will be repatriated. So basically the terms of delivery have been changed, i.e. would be called default in any other era.
6531  Bitcoin / Project Development / Re: [FOSS] P2P portable encrypted messaging and voice communciation (And an app!) on: January 17, 2013, 09:24:45 PM
You might consider using namecoin identities, alias namespace, to provide human-readable authenticated public key exchange and diffie-hellman shared-secret (ECDH) to initiate and establish the AES encrypted channel from there ... it gets around MITM and using CA's for something close to perfect forward security.
6532  Bitcoin / Project Development / Re: [ANNOUNCE] Bitmessage - P2P Messaging system based partially on Bitcoin on: January 17, 2013, 12:44:45 AM
Not sure who you were talking to on IRC but there are only total of 70,000 names registered on namecoin blockchain, hardly "spammed to death" considering the size of the namespaces available, i.e. all dictionary, names, etc in all languages .... 70,000 is drop in the ocean. You are surely misinformed.

Namecoin blockchain is tiny compared with bitcoin at present and is lightweight to run on pc, or you can make calls to the namecoin enabled DNS servers out there if you trust them. Namecoin is still working but just waiting for more applications, this will be an excellent one.

I pulled this out of my IRC log:

[02:45:51] <gmaxwell> It's more or less dead now— pretty much abandoned by its creators... it's been sort of spammed to death because they massively lowered the cost to get names, so there is effectively no anti-dos in it anymore.
[02:46:03] <gmaxwell> Which is quite sad, because it's a useful idea.
[02:46:58] <gmaxwell> There are some fundimental challenges, e.g. it's not possible today to have a lite (not full blockchain) namecoin resolver which is secure.. though its fundimentally possible to create.
[02:49:03] <Atheros2> That's unfortunate. I was thinking about why it couldn't be (or hasn't been) used to alias Bitcoin addresses but I guess that is the reason.
[02:49:23] <gmaxwell> (it seems that all altchains get more or less technically abandoned... none of them even bother to backport critical security fixes from bitcoin)
[02:49:36] <Atheros2> hmm
[02:49:54] <gmaxwell> Atheros2: well it could be but you currently would need a copy of the whole namecoin chain, which is small compared to bitcoin but _huge_ compared to the actual amount of namecoin usage.
[02:50:25] <Atheros2> gmaxwell: I see.
[02:50:27] <gmaxwell> (nmc's database is about 1.1gb right now)
[02:50:39] <Atheros2> gmaxwell: Indeed, that's pretty big.
[02:51:09] <gmaxwell> it would be bigger but it seems it's too boring to even bother attacking right now.

Yeah, gmaxwell has had some sort of vendetta going against namecoiners for a while now ... but he whinges about a lot of things, so who's to know how serious he is?

Why not make it so one can use a Bitcoin address / keypair for messaging?

Bitcoin and Bitmessage keys will be interchangeable. Today I coded the key generation sections; Bitmessage will even save keys in Wallet Import Format.

However Bitmessage will use two keys- one for encryption and one for signing. Thus Bitcoin addresses (which are only a hash of a signing key) wouldn't be sufficient for Bitmessage. It seems to me that Bitmessage addresses could be turned into Bitcoin addresses but not the other way around.

This is gonna be cool.

Now you could store those Bitmessage/Bitcoin keys in a namecoin 'alias' namespace http://dot-bit.org/Namespace:Aliases and have the Bitmessenger client just send to a human-readable name from the namecoin blockchain ... voila ... end-to-end secure, autonomous look-up, authenticated, human-readable messaging system.

That is a good idea isn't it!

Unfortunately, I asked a 'hero member' (I forget who) on IRC about this possibility and why no one was doing it with Bitcoin addresses yet and he said that Namecoin is "more or less dead now. pretty much abandoned by its creators... it's been sort of spammed to death because they massively lowered the cost to get names, so there is effectively no anti-dos in it anymore."

Interesting article but I don't think Satoshi had anything to do with naming the 'satoshi' , unless eponymously has been misused in this instance.

Quote
auspices of pseudonymous developer Satoshi Nakamoto, who eponymously named the currency’s smaller units “satoshis” and issued 100 million to be used across the net.

NB: I think you will find the first actual reference to the 'satoshi' as the smallest unit of a bitcoin (1e-8 btc) naming will be found in this post of mine in the thread discussing conventions for sub-units ... with a prompting from ribuck and kiba, the 'satoshi' was born ... but Satoshi himself was never part of that conversation .... AFAIK  Wink

6535  Bitcoin / Development & Technical Discussion / Re: Standard Check Numbers (checksums for addresses) on: January 16, 2013, 09:40:58 PM
So, to simplify things even further...
IRC Chatlog, v2:

Me: Here's my address 31uEbMgunupShBVTewXjtqbBv5MndwfXhb

Other: check 31uEbMgunupShBVTewXjtqbBv5MndwfXhb

Me: *looks generally over the address, then specifically checks the last 4 characters* confirmed

That's all there is to this. Someone would have to specially go out of the way to bruteforce a typo that wouldn't be caught by doing this easy check.
And the check isn't even necessary since the address won't work in the Bitcoin client that "Other" is using unless it is valid in the first place.

We shouldn't assume that, this is a development thread not technical support.

6538  Bitcoin / Development & Technical Discussion / Re: Standard Check Numbers (checksums for addresses) on: January 15, 2013, 08:54:31 PM
I think it would be quicker, for a human being, to make a cursory inspection of an address followed by a detailed inspection of a check number, as opposed to a detailed inspection of the full address.

That is exactly the same thing as: making a cursory inspection of an address followed by a detailed inspection of the last few characters of the address (as an address can be considered to be the pubkeyhash with its own checksum appended).


Thank you Pieter for explaining to yogi what the condescending others were trying to say to the poor guy without actually spelling out what he needs to do.

Specifically, closely check THE LAST FOUR CHARACTERS of the bitcoin address, there is your built-in checksum.

eg:
12YgtanvDic1y5ZcgW5wCrwwBzSWrSUgXE


I just eyeball the first 4-6 but closely check the last 4-6 ... and never had an issue, hope this helps yogi.

I find your reply disturbing, as I took you at face value to have at least put in the work necessary to understand bitcoin at the protocol level.

My understanding of Bitcoin is fine, thanks. Are you disputing my claim? Where in Satoshis paper is economics addressed?

Quote
Economic topics are covered here, among other things:

Bitcoin Wiki - https://en.bitcoin.it/wiki/Myths - all of these answers are useless?

I said the website is useless, not that page specifically.

Let's see how a casual reader might approach learning about Bitcoin. Bear in mind, they are not very motivated, maybe they figure they have five minutes to take a quick look at this thing they heard about.

Go to bitcoin.org. Click "learn about Bitcoin". That sounds reasonable, doesn't it? See some entirely superficial and nerdy information that is hard to understand, like what does "Double spending is prevented using a block chain" mean? Maybe, they spot the "Bitcoin Wiki" link in the top right corner - not that it's very easy to see. Click it. Get dumped into an un-organized index of all topics with the Technical category applied. Stop.

How about another attempt?

Go to bitcoin.org. Maybe spot the link that says, rather mysteriously, "We use coins! Start here". This is a statement, not a description of what you might find there. OK, so we click and arrive at the site. Click questions/answers. This is better. The 2nd-to-top question on the economics section is "Does hoarding really hurt Bitcoin" But the answer is a, again, a wall of text that superficially might appear to be an official answer of the project, but in reality is just a random opinion from David Schwarz/Joel Katz. It's not a badly thought out argument or opinion, but it's got some very deeply questionable things in it, and the answer doesn't provide any references or citations. For instance it tries to claim that hoarding is usually bad and studies have shown it's bad, but Bitcoin is special.

Actually, "hoarding" or what you may call deflation has been shown in studies to be uncorrelated with depression. That's a critical, key point that should be top and center with a link to the study itself. But there's no mention anywhere to be found.

Finding the myths page requires a lot of clicking around disorganized and unprofessional looking websites. But even if you manage to find the Bitcoin Myths page, the question addressing deflation (which is one of the most common topics you see raised) is buried in question 17, which simply links to the deflationary spiral page, which is enormous and doesn't provide any explanation that fits into a 5 minute browsing session.



Welcome to open source software ..... struggle to understand how you think it would be different. At this point, it is all voluntary effort, except for Gavin A. as I understand it.

The level of documentation fits exactly with the people who have been exposed to bitcoin and felt motivated to wiki, by definition almost. When others arrive they bring it to their acceptable level I'd imagine. If you want professional start a bounty, pay someone maybe?
