And how will you know who someone is if they don't tell you?

If you had the message from the OL guy be pgp signed (with an identity people trust is his) then it would be more likelly people would donate straight to the address on the quote instead of suspecting scam

Awesome if true.

lame

I'm looking to buy around 100 Reais in BTC, prefferably by transfering/depositing the money into the seller's bank account, needs to be an account on a bank here, i don't think i can make a deposit into an account from elsewhere (i'll probably have to go to a physical agency do the deposit)


Eu to pensando em comprar por volta de 100 Reais em BTC, de preferencia pagando com transferencia/deposito na conta de banco do vendedor, acho q precisa ser uma conta num banco aki, acho q não conseguiria fazer o deposito numa conta estrangeira (provavelmente vou ter que ir numa agencia fisica mesmo pra fazer o deposito)

There is no one in my country there

Probably more than how long it takes to just clone the drive (half a tera in a not so recent machine takes more than a whole day)

Depending on what you wanna build, perhaps http://www.emachineshop.com/ would be of your interest

With all the anonymity stuff, how can you ban someone?

Seems darkpools at most give more money to the exchange markets than they would get if the people were trading hiding but without using them

What is the difference between a dark pool and someone selling stuff outside the big trading markets?

A modified client? Would that modified client be able to insert artificially created money (versus "naturally" occurring money that is found with mining) into the network, the illusion ends at the modified client?

What if the bad block include the emergence of mined money (currently 50BTC)  ? How does the network prunes false births of bitcoins?

I'm sorry, i'm not seeing it clearlly, how exactly does other people finding blocks of transactions after the fake transaction results in them indentifying that the fake transaction was fake? Or the other people are actually calculating the same block several times till their blocks agree with the blocks their neighbours calculated?

So, if a single person finds a good hash for a faked block they can get away with it? I thought there was somthing with the network evaluating the job done to confirm if somthing makes sense...

What if some people ganged up and accused an innocent on an obscure matter? The way the first post is written sounds like guilty till paid otherwise....

Who's gonna be enforcing these kangaroo courts? And how would you propose that enforcement to be achieved with a money system that is designed for anonymity and no control of already performed transactions?

And about the first rule there, who will be giving the money if the person who owns money doesn't have any anymore?

That would involve trusting the the store to not clone your wallet, they alreayd do it with regular credit cards....

If you at least needs some sort of challange/response or the very least password or signature from the owner of the account that gets verified by the bank/operator, then things get more secure.

I don't think so, at least not without additional network traffic being required on the store's own equippment confirming things with the block chain and stuff; resources would be better spent by having the store use their own machines to read the customer's card (in whatever form it might be presented, smart card, RFID, bluetooth enabled smartphone etc) and talk with a trusted bank/operator confirming the presence of funds and instructing the initiation of the transfer on behalf of the customer.

And how does that finding zeroes gets used to certify that no double spendings or forged coins are put in circulation?

Do they back those claims?
