Bitcoin kryptowaluta, wprowadzona w 2009 roku przez osob (bd grup osb) o pseudonimie Satoshi Nakamoto[2]. Nazwa odnosi si take do uywajcego jej otwartordowego oprogramowania oraz sieci peer-to-peer, ktr formuje. Bitmonety mog zosta zapisane na komputerze osobistym w formie pliku portfela lub przetrzymywane w prowadzonym przez osoby trzecie zewntrznym serwisie zajmujcym si przechowywaniem takich portfeli.

Kady bitcoin dzieli si na 100000000 mniejszych jednostek, zwanych czasem satoshi.
Odmiennie ni w przypadku wikszoci walut, bitcoin nie opiera si na zaufaniu wzgldem emitenta centralnego. Bitcoin uywa zdecentralizowanej bazy danych, rozprowadzonej pomidzy wzami sieci peer-to-peer do przechowywania transakcji, oraz kryptografii w celu zapewnienia podstawowych funkcji bezpieczestwa, takich jak upewnienie si, e bitcoiny mog by wydane tylko raz przez osob, ktra je posiada w danym momencie.
Topologia peer-to-peer sieci bitcoin oraz brak administracji centralnej czyni manipulacj wartoci bitmonet poprzez produkcj wikszej ich iloci niewykonaln dla jakiejkolwiek rzdowej czy innej organizacji lub jednostki, nadal moliwa jest jednak baka spekulacyjna[5][6]. Budowa bitcoina pozwala na anonimowe posiadanie wasnoci oraz jej transfery.
Bitcoin jest jedn z pierwszych implementacji konceptu zwanego kryptowalut, pierwszy raz opisanego w 1998 r. przez Wei Daia na licie mailingowej cypherpunkw[7].
Bitcoin opiera si na transferze kwot midzy rachunkami publicznymi, przy uyciu kryptografii klucza publicznego. Wszystkie transakcje s publiczne i przechowywane w rozproszonej bazie danych. W celu zapobieenia podwjnemu wydawaniu, sie implementuje rodzaj rozproszonego serwera czasowego, uywajc koncepcji acuchowych dowodw matematycznych wykonanych dziaa (tzw. Proof of Work, w skrcie PoW). Dlatego te caa historia transakcji musi by przechowywana w bazie, a w celu ograniczenia rozmiaru magazynu uywane jest drzewo funkcji skrtu.
Bitcoin jest implementacj konceptu b-money autorstwa Wei Daia oraz Bitgold autorstwa Nicka Szabo, opart na sieci P2P. Zasady funkcjonowania systemu s opisane w specyfikacji technicznej stworzonej i opublikowanej w 2008 roku przez Satoshiego Nakamoto[2][8].
Kada osoba uczestniczca w sieci bitcoin ma portfel zawierajcy dowoln liczb par kluczy kryptograficznych. Klucze publiczne, zwane te adresami bitcoin, dziaaj jako miejsce rdowe oraz miejsce docelowe dla wszystkich patnoci. Odpowiadajce im prywatne klucze autoryzuj patnoci tylko dla posiadajcego je uytkownika. Adresy nie zawieraj adnej informacji na temat ich waciciela i s zazwyczaj anonimowe[9].

Uytkownicy bitcoina mog posiada wiele adresw, a waciwie mog generowa nowe adresy bez adnych ogranicze, poniewa generowanie nowego adresu jest relatywnie natychmiastowe, rwne wygenerowaniu nowej pary kluczy prywatnego/publicznego oraz nie wymaga kontaktu z reszt sieci.

Tworzenie jednorazowych adresw wykorzystywanych do pojedynczego celu moe te pomc w zachowaniu anonimowoci uytkownika.
Bitmonety zawieraj klucz publiczny (adres) aktualnego posiadacza. Kiedy uytkownik A przetransferuje jak ilo do uytkownika B, A rezygnuje z ich posiadania, dodajc klucz publiczny (adres) B do tych monet oraz podpisujc je wasnym kluczem prywatnym[10].

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

Bitcoin Core is the the backbone of the Bitcoin network. Almost all Bitcoin wallets rely on Bitcoin Core in one way or another. If you have a fairly powerful computer that is almost always online, you can help the network by running Bitcoin Core. You can also use Bitcoin Core as a very secure Bitcoin wallet.

Bitcoin
Bitcoin is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network.
The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch", also use open source licensing.
Bitcoin is the first successful implementation of a distributed crypto-currency, described in part in 1998 by Wei Dai on the cypherpunks mailing list. Building upon the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities.

FAQ – Bitcoin
Find answers to recurring questions and myths about Bitcoin.
Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence.
Bitcoin is the first implementation of a concept called "cryptocurrency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010 without revealing much about himself. The community has since grown exponentially with many developers working on Bitcoin.
Satoshi's anonymity often raised unjustified concerns, many of which are linked to misunderstanding of the open-source nature of Bitcoin. The Bitcoin protocol and software are published openly and any developer around the world can review the code or make their own modified version of the Bitcoin software. Just like current developers, Satoshi's influence was limited to the changes he made being adopted by others and therefore he did not control Bitcoin. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper.
Nobody owns the Bitcoin network much like no one owns the technology behind email. Bitcoin is controlled by all Bitcoin users around the world. While developers are improving the software, they can't force a change in the Bitcoin protocol because all users are free to choose what software and version they use. In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and allows a user to send and receive bitcoins with them. This is how Bitcoin works for most users.
Behind the scenes, the Bitcoin network is sharing a public ledger called the "block chain". This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This is often called "mining". To learn more about Bitcoin, you can consult the dedicated page and the original paper.
Yes. There is a growing number of businesses and individuals using Bitcoin. This includes brick and mortar businesses like restaurants, apartments, law firms, and popular online services such as Namecheap, WordPress, and Reddit. While Bitcoin remains a relatively new phenomenon, it is growing fast. At the end of August 2013, the value of all bitcoins in circulation exceeded US$ 1.5 billion with millions of dollars worth of bitcoins exchanged daily.
While it may be possible to find individuals who wish to sell bitcoins in exchange for a credit card or PayPal payment, most exchanges do not allow funding via these payment methods. This is due to cases where someone buys bitcoins with PayPal, and then reverses their half of the transaction. This is commonly referred to as a chargeback.

FAQ - Bitcoin
BTC Guild – Bitcoin Mining Pool
BTC Guild will be shutting down its mining servers on June 30th, 2015 at 23:59 UTC. Users will still be able to log in and retrieve their history (CSV exports on the settings page) and request withdrawals until September 30, 2015. Why is BTC Guild Shutting Down? This is the second time BTC Guild has announced closure, but this time the decision will not be reversed. The reasons have not changed much since the original announcement.
As mining has become more centralized, BTC Guild has continuously shrunk in proportion to the network, now being less than 3% of the network hash rate. The costs of running the pool have not changed, and the amount of funds at risk in the event of a compromise is significantly higher than what the pool could ever recover from. When the pool was 20-30% of the network, the amount of funds at risk was slightly higher, but the ability for the pool to recover from that loss was present. At 3% of the network, the pool would not be able to recover from such a loss.
Additionally, the NYDFS BitLicense regulations have now become finalized, and the final regulations have enough gray area that BTC Guild is at risk. The fact that BTC Guild is not in New York does not matter, since it would be doing business with New York residents while they are physically in New York. This fact makes it possible for New York to attempt to claim jurisdiction to enforce regulations. Whether or not BTC Guild could win in defense of such an attempt is irrelevant, since the cost of defending the pool would be greater than any income the pool is expected to generate going forward.
Finally, I have been growing concerned for some time now about attempts to defraud pools. The pool's luck has been on a decline for over a year. The luck on a few other pools has also shown a negative trend. While it is not impossible that it's a coincidence, this is something I have been constantly made aware of and am helpless against. There is no way to know whether it's just bad luck, a small bug in older miners (BTC Guild probably has the highest percentage of first/second generation ASICs) resulting in a few % of block-solving shares to disappear, or a large pool trying to hurt the competition (many of the largest pools have large private mining operations now). It would only take a fraction (1 PH/s or less could do it) to cause significant harm to a competing pool, and that activity could be masked by proxies and multiple accounts to be impossible to catch.
The PPLNS shift length will be steadily reduced starting June 16th. This means that more shifts will likely end with 0 blocks, but shifts that find blocks will receive a larger amount than they would have previously. It is not recommended that users wait until the last minute to change pools.
The minimum balance for a manual withdrawal is reduced to 0.0001, and will not require a transaction fee to be paid in order to request the withdrawal.
Users will have until September 30, 2015 to issue the request for their final withdrawals.
The risk of users being cheated or stolen from as a result of transferring pool ownership is not something I am willing to accept. This is part of the reason the pool is closing in the first place: Risk of users losing funds because the pool would not be able to cover losses in the event of compromise.
I will not be entertaining offers on purchasing the pool this time around. There is no (reasonable) price the pool would be sold for.
Thank you to all the users and the Bitcoin community for making BTC Guild a success for the last four years. It has been hard to finally make this call a second time with the determination to not reverse the decision. You will still be able to find me around the Bitcoin Talk forums (outside of the Pools subsection for once), and on IRC in #btcguild (and probably #bitcoin once the pool winds down).

Why Bitcoin Popular Opinion What is Bitcoin?
With the Bitcoin price so volatile everyone is curious. Bitcoin is extremely complicated and no one definition fully encapsulates it. By analogy it is like being able to send a gold coin via email. It is a consensus network that enables a new payment system and a completely digital money.
It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. Bitcoin was the first practical implementation and is currently the most prominent triple entry bookkeeping system in existence.
The first Bitcoin specification and proof of concept was published in 2009 by an unknown individual under the pseudonym Satoshi Nakamoto who revealed little about himself and left the project in late 2010. The Bitcoin community has since grown exponentially.
Satoshi's anonymity often raises unjustified concerns because of a misunderstanding of the open-source nature of Bitcoin. Everyone has access to all of the source code all of the time and any developer can review or modify the software code. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper.
Nobody owns the Bitcoin network much like no one owns the technology behind email or the Internet. Bitcoin transactions are verified by Bitcoin miners which has an entire industry and Bitcoin cloud mining options. While developers are improving the software they cannot force a change in the Bitcoin protocol because all users are free to choose what software and version they use.
In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and enables a user to send and receive bitcoins.
Behind the scenes, the Bitcoin network is sharing a massive public ledger called the "block chain". This ledger contains every transaction ever processed which enables a user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses therefore allowing all users to have full control over sending bitcoins.
Thus, there is no fraud, no chargebacks and no identifying information that could be compromised resulting in identity theft. To learn more about Bitcoin, you can consult the original Bitcoin whitepaper, read through the extremely thorough Frequently Asked Questions, listen to a Bitcoin podcast or read the latest Bitcoin news.

Bitcoin isnt the future of money its either a Ponzi …
(Photo by Ethan Miller/Getty Images)
Sometimes it's hard to tell whether Bitcoin is more like Ponzi scheme or a pyramid scheme.
Whatever it is, though, it isn't a currency. It's a tech stock. Each Bitcoin is really a share in a systemthat seems to make it cheaper to transfer things onlinemoney, stocks, bonds, even the deed to your houseby cutting out the middleman. Well, kind of. Bitcoin doesn't remove the middleman so much as replace himwith middlemen who don't make you pay much, but make society as a whole do so instead. Is this progress?
It's supposed to be. Ever since the early days of the Internet, people have been trying to figure out how to transfer money online without having to go through the financial system. The problem, though, is if Isend youmoney, how do you know I haven't already spent it or sent it to somebody else? You don't. So the only solution has been to have a trusted third-party, like a bank, sit in between us. I send the money to the bank, it verifies that I actually have this money to send, and then it sends it on to you, all for a 2 percent fee, of course.
Bitcoin's breakthrough is to have a decentralized network of "miners" sit in between us instead. Now, remember, these miners are trying to win new Bitcoins by solving computationally-taxing math problems. The clever part, though, is that in the process of doing so, they also create a public ledger of every single Bitcoin transaction, what's called the blockchain. That includes every Bitcoin that's ever been won, every Bitcoin that's ever been used, and every Bitcoin that's ever been transferred. So now we don't need a bank to know that I have the money I'm sending to you, and that I'm only sending it to you. The miners confirm all this. And the best part is that instead of having to pay the bank myself to do this, the system pays the miners in new Bitcoins.
The question, though, is howyou get people to mineBitcoin to begin with. Sure, you can tell them that Bitcoin is digital money they can use to buy things online, but they already have money they can already use to buy things online. And while merchants would be more than happy to save the 2.5 percent they pay in credit card transaction fees, customers are a lot more more blas since they don't pay them directly.The answer, then, was to do what makes anything popular: make it exclusive. Specifically, Bitcoin limits the total number of coins that will ever be created to 21 million.Now, for Bitcoin's first year and a half, as Nathaniel Popper documents in hispage-turning history Digital Gold, there were still only a handful of people, if that, mining it. But that began to change when libertarians, who were convinced, just convinced, that the Federal Reserve's money-printing would mean the doom of the dollar, discovered Bitcoin and its non-inflatable money supply. A boom was born.
But what made people mine Bitcoins is what has kept from spending Bitcoins. Think about it like this. Bitcoin's finite supply means that its price should go up, and keep going up. So if you have dollars that are losing a little value to inflation every year and Bitcoins that are gaining it, which one are you going to use to buy things with? The question answers itself, and it raises another. Why would this ever change? Unless you can't buy something online with dollarslike drugsyou'd always want to use your dollars instead. Buying things with Bitcoin would be like cashing out your Apple stock in 1978 to go grocery shopping even though you have plenty of actual cash lying around.
The catch-22is people buy Bitcoins because they think the price will go to infinity and beyond once everybody uses them, but they don't spendtheir own Bitcoins because they think the price will go to infinity and beyond once everybody else uses them. And so nobody uses them. But if nobody uses them, then the price will stay stuck at something a lot less than infinity let alone beyond. So the Bitcoin faithful have tried to not only convert people, but also convince them to martyr themselves, financially-speaking, for the crypto cause. It goes something like this. Hey, do you want to hear about the future? It's a digital currency called Bitcoin that lets you spend or move your money online without paying any fees. Sounds great. How does it do that? Well, Bitcoin saves you money by making transactions irreversible. So ... if I get scammed, I got scammed? There's nothing I can do about it? Yes. Okay, but is it at least easy to use? The thing is, I don't actually use it. I just hoard it. I'm waiting for some greater fools to push up the price by using theirs. Oh. Yeah. So you should buy some Bitcoins and use yours. I'll get back to you on that.
But Bitcoin is good for something other than redistributing wealth from one libertarian to another. That's transferring money, or anything else for that matter, online. "The design supports a tremendous variety of possible transaction types," Bitcoin's shadowy inventor Satoshi Nakamoto wrote back in 2010, including"escrow transactions, bonded contracts, third party arbitration, multi-party signature, etc." So anytime you needto send any kind of financial asset or agreement to somebody else, you can send it along with a Bitcoinand, through the beauty of the blockchain, avoid having to pay a lot of fees. That's why Wall Street banks are looking into whether they can build their own blockchains to cut costs before their competitors do. And while sending money is cheap within the U.S., it's not not across international bordersthe average transfer fee, according to the World Bank, is 7.5 percent. It's not hard to imagine, in other words, that Bitcoin could claim a big chunk of the $500 billion remittance market, although the difficulty of actually getting the physical cash to people in developing countries is still a significant hurdle.
Wait a minute, though. How does the blockchain cut costs again? Remember, instead of you paying the bank a fee to process a transaction, the Bitcoin system pays miners new coins to do so. Then these transactions get added to the list of all others in the public ledger, the blockchain. Butanytime it seems like you're getting something for nothing the costs are probably just being hidden. What are those costs? Well, Bitcoin mining is a pretty expensive business. Even the most specialized computers, which mine Bitcoins and only mine Bitcoins, require a lot of energy. So much so that Bitcoin miners have set up shop in far-flung places like Iceland where geothermal energy is cheap and Arctic air is cheaper stillfreefor them to run and cool off their machines at the lowest possible price.
