<\/a><\/div>\nHowever, if you are not living on the American soil, be aware that it exists the same kind of initiative, for example by the University of Cumbria in the United Kingdom, or also by the University of Nicosia, in Cyprus. The latter also features a degree in \u00ab Digital Currencies \u00bb for its student that highlights Bitcoin.<\/p>\n
Bitcoin Boulevard<\/strong><\/h2>\nAre you visiting the Netherlands? Do not miss the Bitcoin Boulevard located in the Hague, which offers a unique feature: A high majority of shopkeepers who are located on the two streets that go alongside the channel \u2013 Bierkade and Groenewegje \u2013 now accept Bitcoin, following an initiative submitted by Hendrik Jan Hilbolling and Peter Klasen.<\/p>\n
You can therefore have dinner in one of the nine restaurants that participate to the operation, or you can go shopping in the art gallery also located there, thanks to your favorite cryptocurrency. Some other streets seem to follow the same move, in particular in the United States: for example, the North-American Bitcoin Boulevard located in Cleveland Heights, in Ohio.<\/p>\n
The first transaction<\/strong><\/h2>\nBitcoin has enabled 43 472 379 transactions since its creation through its network. However, you will be certainly interested by knowing who initiated the first transaction.<\/p>\n
It is no one else but Satoshi Nakamoto, the fantastic Bitcoin and underlying technology creator, who sent 100 bitcoins to Hal Finney on January 12th, 2009.<\/p>\n
Hal Finney has been involved for a long time in the cryptography community. For years, he has been working with PGP Corporation, developing one of the most famous encryption system (The company was holding the rights for the PGP system, developed at the origin by Phil Zimmermann). He launched then the first anonymous remailer used to encode his emails, and was also implicated in the cypher-punks\u2019 movement.<\/p>\n
On a Bitcointalks post, Hal explained how it happened:<\/div>\nWhen Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run Bitcoin [client]. I mined block 70-something, and I was the recipient of the first Bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.<\/div>\n<\/div>\nAfter a few days, Bitcoin [client] was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there, at the beginning. It\u2019s one of those glass half full half empty things.<\/div>\nThe million dollar Bitcoin pizza<\/strong><\/h2>\nOn May 22nd, 2010, a Bitcoiner named Laszlo Hanyecz paid to a Bitcointalks forum user not less than 10 000 BTC for two Papa John\u2019s pizzas. What can be considered as an incredible amount (5 619 700$ worth of BTC nowadays) was equivalent to 30$, according to the exchange rate applied at this time, estimated to 0,003 cents per Bitcoin. Mr. Hanyecz said he had acquired these bitcoins by mining on his computer.<\/div>\n<\/div>\n\u201cIt wasn\u2019t like bitcoins had any value back then, so the idea of trading them for pizza was incredibly cool,\u201d said Mr. Hanyecz. But when asked about the current value of the cryptocurrency, he adds: \u201cNo one knew it was going to get so big.\u201d<\/div>\n<\/div>\nQuestioned about possible regrets, he adds:<\/div>\n<\/div>\n\u201cNo, not really,\u201d Mr. Hanyecz said. Then he sold his bitcoins when the price was around 1$, getting 4000$ \u201cThat was enough to get a new computer and a couple of new video cards, so I\u2019d say I ended up on top.\u201d<\/div>\nA Bitcoin master swindle<\/strong><\/h2>\nOn November 4th, 2011, a BitcoinTalks forum user named pirateat40 has announced the creation of a Bitcoin investment fund, promising to the investors a return on investment of 7% per week.<\/div>\n<\/div>\nDespite numerous suspicious elements and ridiculous incentives to invest such as \u201cIt\u2019s growing, it\u2019s growing!\u201d, \u201cI have yet to come close to taking a loss on any deal,\u201d and even \u201crisk is almost 0\u201d, the fund encountered a fast and great success: according to the SEC report, more than 700 467 BTC, the equivalent of 411,7 million dollars, have been collected by Trendon Shavers, a.k.a pirateat40.<\/div>\n<\/div>\nContrary to the presentations made to the investors, the fund was not performing any trading activities; in addition, the users have never seen their \u00ab invested \u00bb bitcoins again.<\/div>\n<\/div>\n<\/div>\n\n![\"\"](\"https:\/\/i.imgur.com\/lKKfpQV.png\")

64% is the estimated part of present \u00ab ghost \u00bb Bitcoins on the Blockchain according to a study made by the California University<\/strong><\/h2>\nThe history of Bitcoin is regularly studded by stories of users who have lost their private keys and who are not still able to use their bitcoins. See two examples of bitcoins who have not been spent for a very (very!) long while:<\/div>\n<\/div>\n\u2022 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF : 75,957 bitcoins which have never been spent. Address created on March 1st 2011.<\/div>\n<\/div>\n\u2022 12tkqA9xSoowkzoERHMWNKsTey55YEBqkv : 28,150 bitcoins which have never been spent. Address created on April 5th, 2010.<\/div>\n<\/div>\nThe computing power of the Bitcoin network is 7468 times higher than the one of the cumulative 500 world supercomputers<\/div>\n<\/div>\nIndeed, the computing power of the whole Bitcoin network is estimated to 2 046 364 Pflop\/s, against 274 Pflop\/s for the cumulative 500 most powerful world supercomputers.<\/div>\n<\/div>\nFirst of all, it is important to note that Bitcoin miners are not performing any floating point operations (FLOP) but only integer calculus. How have we then been able to proceed? It\u2019s very easy, in fact:<\/div>\n<\/div>\n1 hash = 6.35K integer operations<\/div>\n1 integer operation = 2 floating point operations<\/div>\n1 hash = 12.7K floating point operations<\/div>\n<\/div>\nThen, using this rate of one hash = 12,7K flop, and by analyzing the current hashrate of the Bitcoin network which peaks to 161 131 086 gh\/s on July 31st 2014, we get an estimation of 10^9*161131086 H\/s * 12700 = 2 046 364,7922 Petaflops.
