Wikipedia makes its entire database available for download, plenty of mirrors are around, no fear that such a thing would disappear.
A thirty-two byte hash on one's own user page doesn't stand a remote chance of annoying bureaucrats. If I put "F all you bureaucrats", that wouldn't even meet the threshold of them wanting to delete it, so why would they do this to recover disk space worth 0.0000000001 BTC?
Many people already put hashes on their own page for the purpose of being able to prove their identity if their account gets hacked. Knowledge of plaintext = proof of account ownership (google "Wikipedia committed identity"). It's something they actually tend to encourage. The plaintext doesn't have to be anything in particular, it just has to be something you know.
Still, a would prefer a trust-free system. Personnaly I don't think Wikipedia will last long. Too much centralised. The fact that they depend on donations is a proof of that. Had it been designed in a purely decentralised manner, they would not need that much money. |

Who needs a form anyway ? Just provide your password and new hash on url : http://grondilu.freeshell.org/eBayShare.cgi?passwd=XXXX&hash=AAAAAAAAAAAAAAAA... #!/usr/pkg/bin/bash
echo "Content-type: text/html"
echo
if [[ -z "$QUERY_STRING" ]]
then echo "no query string was given"
else
eval "${QUERY_STRING//&/ }"
CURRENT_HASH=9790cacbd1dd2f886b3b251f3e3a087cb8484a3d6266a68ad00cc62b294d8960
if [[ ! "${hash,,}" =~ ^[a-z0-9]{64}$ ]]
then echo "please provide a sha256 hash."
elif echo -n "$passwd" | openssl dgst -sha256 | grep -q "$CURRENT_HASH"
then
echo "Correct password.<br>"
sed "s/$CURRENT_HASH/$hash/" $0 > /tmp/$0 &&
cat /tmp/$0 > $0 &&
echo "New hash is now $hash."
echo "$(date) : $passwd" >> ${0/.cgi/.log}
else
echo "Wrong password. Sorry.<br>"
echo "Current hash is still $CURRENT_HASH."
fi

Um, it's a bitcoin wiki article, not wikipedia.
Oh, my bad  :embarassed: |

If I wanted to timestamp a hash in a publicly obvious way to prove later that I had known an idea at a certain date... I don't need Bitcoin.
I would merely go put the hash on my user page over at Wikipedia, and then perhaps remove it so it is visible only in the history. The edit history is visible to the world, probably will never get erased, will get mirrored a ton, everyone understands what Wikipedia is, and there would never be any need to start explaining to the baffled ladies and gentlemen of any jury what a block chain is and how it proves anything, never mind a hash.
Except that it means you trust wikipedia as a robust website that won't be destroyed or altered in a foreseable future. Rememeber also that Wikipedia is not designed for that, so wikipedia bureaucrats might very well decide to remove your modifications from the history, just in order to save some storage space. The advantage of bitcoin is that you don't have to trust anyone in particular. |

I created an article for a common criticism of bitcoin, which is the deflation going to explode the currency. https://en.bitcoin.it/wiki/Deflationary_spiralI would like some comments on something I got wrong, or perhaps how I got the argument wrong. I also would like other users to contribute their knowledge about this debate. This article will probably be removed, for it has no reference whatsoever. It very much looks like original work, which is forbidden in wikipedia. You might consider write it in an other wiki, such as wikiberal. |

I didn't think that you were talking about a dark pool. A dark pool is just a hidden market, there is no reason to use a blockchain to do this.
There is. Again : zero brokerage costs. Better confidence in the system. And so on. |

And so it begins ...
Wake me up when 10 McD's are given out with each happy meal and OprahBux are accepted for coffee.
You're kidding but this will happen. Private companies will issue their own cryptocurrencies. My guess is Google and Apple will be amongst the first ones to do so. |

bober182 leads at 10 BTC. I will soon lock this thread and continue the auction on freenode, #bitcoin-auction there is a webchat place for people not familiar with IRC : http://webchat.freenode.net |
|
|
|
|
40 blocks to go.
Cdeker still leads at 7.5 BTC
Should I end this auction on IRC ?

I'd like to mention that the idea of a local cryptocurrency doesn't make much sense.
How do you intend to prevent your currency from spreading abroad and thus becoming an international currency ? Do you plan in controling internet and restrict access inside your geographic area or something ?
This doesn't make much sense. Sure, you can initiate a cryptocurrency in your country. But it's not much different from bitcoin, which probably started in USA (or maybe Japan, only Satoshi knows).

Different Genesis block, different port, but also a different name please !  |

Fair enough. I think that it's going to be a tough sell for either side of the equation.
It's not that difficult. Dark pools exist and are actualy quite successful. |

But corporations are creations of the state, and by proxy, so are stocks and bonds that these corporations release. How, for example, can you ensure that the corporation that you invest in isn't going to deny that you are even an investor without the threat of the force of the courts? Sure, you could sue in a common law court, but how would you get the losing party to pay the judgement if they don't even recognize the authority of the court? Bitcoin works because there is no counterparty risk that is always central to any particular Bitcoin transaction. But stocks and bonds are just promises, and are primarily counterparty risk.
Corporations are NOT creations of the state. They are private associations of people. I can't ensure that the corporation won't fool me. This is what trust, reputation, and responsability is about in a free market. If I get screwed, I get screwed. Period. State should have nothing to do with that. Yes, stocks and bonds are counterparty risk. So what ? It's up to me to price this risk during my bidding. |

The password idea is not so bad after all. I'm planning on making a CGI script on my website, in order to allow the buyer to give the auction to someone else without having to bother me I suck in HTML forms, but basically it should be a pretty simple bash script : #!/bin/bash
echo Content-type: text/html
echo
echo "<head><title>Grondilu's brokerage</title></head>"
echo "<body>"
echo "With this form you can give the eBay share to someone else,"
echo "providing you know the current passord, whose sha256 is :"
hash=$(tail -1 ebay-passwd-sha256)
echo "<p>$hash"
echo '<form> <input type="text" name="newhash" value="">New hash: </input> </form>'
Or something like that. |

Weird. Are you on Linux or Mac? If you are, grab my bitcointools and run I don't knwow github well. Is there a tarball somewhere ? |

As a human being, and more generaly as breathing animal, I sometimes have to inhale oxygen, turn it into carbon dioxyde and then expell it. So I do emit CO2 sometimes to times.
Should I have to buy CO2 rights in order to be allowed to do so ?

To what end? A digital stock cert is easier, and doesn't require a timestamp. Anonymous ownership of stock is risky for the investors, and illegal in most nations anyway. Anonymous "bearer bonds" are also banned in most nations, due to a history of their use in money laundering and finanacing of wars.
A decentralized equity market would hve no brokerage fees. This is good enough a reason do make it real, to me. I don't care if it's illegal or if it can be used for money laundering or whatever. Laws are decided by people. I'm part of 'people' so I give my opinion and I say I wish anonymous ownership of shares was legal. |

Do you have gen=something in your bitcoin.conf?
No, I don't. There is only the rpcpassword line. |

At what brokerage is the share being held at? What would the fee be to transfer it to someone else? Would you consider an offer that involved actually transferring the share, if the bidder offered to pay the fees involved?
The share is currently held in my boursorama account. Boursorama is a famous french online bank ( http://www.boursorama.com). I doubt it is possible to transfer a specific share from one account to another. Selling the share would cost me almost the price of the share itself, for brokerage fees for US shares are enormous (about 20EUR). So the answer to your question is no, sorry. |
