1  Bitcoin / Bitcoin Technical Support / regarding: bitcoind's memory of spent transactions on: November 23, 2013, 11:55:49 PM
I had thought it would be possible to navigate the river of Bitcoin history via the RPC API.

For block headers, it seems, this is true:
Code:
$ getblock 000000001c920d495e1eeef2452b6d1c6c229a919b28196c103ecffebabee141
{
    "hash" : "000000001c920d495e1eeef2452b6d1c6c229a919b28196c103ecffebabee141",
    "confirmations" : 78106,
    "size" : 647,
    "height" : 50001,
    "version" : 1,
    "merkleroot" : "ee3a2d2b895cafacff526d06a55b55e049cf84a9735e4a63f7fd08f96d0f4649",
    "tx" : [
        "e1882d41800d96d0fddc196cd8d3f0b45d65b030c652d97eaba79a1174e64d58",
        "7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a",
        "f84761459a00c6df3176ae5d94c99e69f25100d09548e5686bd0c354bb8cc60a"
    ],
    "time" : 1270917100,
    "nonce" : 56717043,
    "bits" : "1c2a1115",
    "difficulty" : 6.08547691,
    "previousblockhash" : "000000001aeae195809d120b5d66a39c83eb48792e068f8ea1fea19d84a4278a",

}
However, should I dig deeper...
Code:
$ getrawtransaction e1882d41800d96d0fddc196cd8d3f0b45d65b030c652d97eaba79a1174e64d58

Code:
$ getrawtransaction 7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a
error: {"code":-5,"message":"No information available about transaction"}
The pattern, of course, is that the first transaction's outputs remain unspent, whereas the second transaction's coins have long since moved elsewhere.

If historical, spent transaction data can be queried via another interface in the reference client, or if there is another client that can provide it, I should very much like to know.

I'm afraid I already found another seller. But I'll keep you in mind for the future.

It can wait. I have to prepare my payment, regardless.

Pleasant dreams.
Your payment has been submitted.

bitstamp = 499.xx at the moment  lets round to 500

walmart shows 206.88 as the price. ok to round to 210 for this?  0.42 BTC assuming btc is still ~500



edit...well that escalated quickly.... up $5 on exchange in the time it took to type all that 0_o
Heh. Interesting times.

In any case, 0.42 BTC is fine.
6  Economy / Currency exchange / Re: [WTB] One-Time Prepaid Visa/Mastercard/AmEx Gift Card on: November 18, 2013, 06:10:01 AM
how many dollars are you looking to get on the card?  <800 i could do today. could do much much more later this week wednesday/thursday when funds clear
A $200 balance is fine.

What is your price?

PS. To be clear: this would be a 100% digital transaction. I neither need nor want a physical card; the necessary ID numbers to use it online are sufficient.
7  Economy / Goods / [FILLED][WTB] One-Time Prepaid Visa/Mastercard/AmEx Gift Card on: November 18, 2013, 05:33:03 AM
In need of a prepaid gift card.

As chargebacks and "stolen card" reports are a problem, this must be from someone with a good reputation. I am willing to pay a significant commission.

Please reply here or PM me.

I'm willing to pay 0.135 BTC for your card. That is, about the going rate.

If you are not willing to send first, I'll need either some proof of your trustworthiness, or your consent to use an escrow service.

Please reply as soon as possible.
10  Economy / Services / Re: Wanted: temporary (1 month) mail-address. 1/4 bitcoin offer. on: October 20, 2013, 12:45:03 AM
Being homeless, traveling in an RV, staying in hotels, all legal reasons to want mail scanning. Google it and you may even find a cheaper service than 1/4 BTC.
Alas, every mail scanning service I could find required prospective customers to already have an address. Unless you have recommendations?

Give us a hint to the illegal activity you are planning. 
I fear I'll have to contend with this assumption no matter what I say.

However, I may as well reply regardless: I am planning nothing illegal. That's the point of going to all this trouble. If I was willing to provide a fictitious address to commercial mail scanners, I would simply do that, instead of offering a quarter-bitcoin to a stranger to rifle through my letters.
11  Economy / Services / Re: Wanted: temporary (1 month) mail-address. 1/4 bitcoin offer. on: October 19, 2013, 10:19:56 PM
because we all know what the address will really be used for haha.
And what might that be? Something unsavory, I assume? Elaborate, and I may be able to adjust my request to exclude the possibility.
12  Economy / Services / Wanted: temporary (1 month) mail-address. 1/4 bitcoin offer. on: October 19, 2013, 09:26:20 PM
I am looking for an address at which I can receive mail, until I can establish a permanent address of my own.

I don't expect to receive much mail. As for the mail that I do receive, the following arrangement is preferred:
  • that the mail be scanned or photographed clearly enough to read
  • that, once scanned, the scans be sent to me
  • that, once forwarded, the mail and all digital copies be destroyed

I am only willing to pay in bitcoins. No physical forwarding is required or expected. A North American address is preferred but not required.

I am willing to pay in full, in advance. Therefore, I would prefer that the counterparty to this arrangement be someone whose reputation is worth more than a quarter-bitcoin.

Thank you for your consideration.

Perhaps I have been misled.

I was under the impression that "inflation" and "deflation" referred not to an increase or decrease in the size of the monetary supply, but rather to an increase or decrease in the ratio of money to goods.

That is, if the economy and the money supply are both growing, it isn't "inflation" - that for it to be "inflation" requires money to be created faster than the valuable things upon which the money might be spent.
14  Other / Beginners & Help / Re: Hyperdeflation, own half the world by headstart - don't you care at all? on: March 25, 2012, 06:19:01 PM
And we already know how that works: Value of the currency rises (other goods drop) to the point where the economy cannot sustain it any longer, then a depression follows as correction, and then it starts again. In the process, more and more assets are transferred to the money power.
A scenario which closely resembles the bubbles we see in modern currencies.

I am uncertain. There is a part of me which imagines that the current system also provides advantages to the money power, via access to the mechanism by which money is created. And these advantages are removed in a system where anyone can become a transaction signatory, given a landlord who pays utilities.

The other side of the coin, however, is that, if Bitcoin is truly an "experiment", then people ought to be willing to learn from it. If your proposed scenario is truly how things go, then I should hope that, once the story starts to play out in our economy, people will be wise enough to notice, and will react by creating another blockchain that has more Keynesian properties - leveling out to, say, a one percent expansion per year, rather than zero.

is it true, that paypal converts € in BTC?
and if so, that they restrict the amount exchanged?
I am aware of no Paypal "conversion" for Bitcoins.

In fact, as far as I am aware, Paypal itself avoids dealing with Bitcoins wherever possible.

I was also, at first, quite worried about such things.

Certainly, if the currency deflates at a high enough velocity, it stops circulating, and becomes worthless as a mode of exchange.

But I have been convinced to let things run their course now - to see what happens.

Perhaps these may help assuage your fears:

  • I doubt Bitcoin will ever be the mode of exchange for all goods, everywhere. It seems to me more likely that it will simply become another economy, alongside the various parochial fiat economies.
  • Should the Bitcoin economy dominate regardless of the above, only an early adopter who has held their coins entirely through the currency's meteoric rise has the capability of becoming a plutocrat. Wouldn't that be strange, for someone to see their coins worth $100? And then $1000? And still not sell? And even then, if that person were to wait until they hold 1% of the money in the world... they could never spend it all at once. It would be like a man who finds a mountain made of a single flawless diamond, and proceeds to try to sell it, and in doing so sends the price of diamonds down in flames. Such riches are difficult to actually use.
  • But putting such theoretical plutocrats aside, here is the argument that convinced me to not be so concerned about the Bitcoin's deflationary properties: on this Earth, there has never been a deflationary currency. There has never been a currency whose supply increases predictably and significantly more slowly than the supply of the goods it represents. We do not actually know how such a currency will behave in the wild, and while we may speculate, we are speculating. Bitcoin is, in some ways, still an experiment.

Using the CPU of this machine can still be profitable.

You need only use it on Litecoin, or another similar currency whose trap-door isn't yet worth GPU attention, and then trade in your winnings if you'd rather have Bitcoins.
18  Other / Beginners & Help / Re: lmao 3853 hashes per second LITECOIN on: March 20, 2012, 04:57:17 AM
These days, it seems that any cryptocurrency with enough adoption to have value, also has enough adoption for the miners on the network to completely overpower a low-end CPU.

So I suppose the real question is, what is your goal in mining?

If your goal is to help secure the network, I suppose you can just rest easy, knowing it's in very capable hands.

If your goal is to have some coins to play around with, perhaps getting coins from faucets (sites that give out a small number of BTC to new users) would be a better approach.

If your goal is to get coins, and faucet coins aren't enough for you... unfortunately, as a result of BTC being worth something, you need to give up something of value to get them. Whether that means buying them on an exchange, or purchasing video cards whose hash power can keep up with the network, or selling things of value to other users and taking payment in coins.

No free lunches under the sun.
