Bitcoin adalah sebuah uang elektronik yang di buat pada tahun 2009 oleh Satoshi Nakamoto. Nama tersebut juga dikaitkan dengan perangkat lunak sumber terbuka yang dia rancang, dan juga menggunakan jaringan peer-ke-peer yang menghubungkan semuanya. Tidak seperti mata uang pada umumnya, bitcoin tidak tergantung dengan mempercayai penerbit utama. Bitcoin menggunakan sebuah database yang didistribusikan dan menyebar ke node-node dari sebuah jaringan P2P ke jurnal transaksi, dan menggunakan kriptografi untuk menyediakan fungsi-fungsi keamanan dasar, seperti memastikan bahwa bitcoin-bitcoin hanya dapat dihabiskan oleh orang mempunyainya, dan tidak pernah boleh dilakukan lebih dari satu kali.
Desain dari Bitcoin memperbolehkan untuk kepemilikan tanpa identitas (anonymous) dan pemindahan kekayaan. Bitcoin - bitcoin dapat disimpan di komputer pribadi dalam sebuah format file wallet atau di simpan oleh sebuah servis wallet pihak ketiga, dan terlepas dari semua itu Bitcoin - bitcoin dapat di kirim lewat internet kepada siapapun yang mempunyai sebuah alamat Bitcoin. Topologi peer-to-peer bitcoin dan kurangnya administrasi tunggal membuatnya tidak mungkin untuk otoritas, pemerintahan apapun, untuk memanipulasi nilai dari bitcoin - bitcoin atau menyebabkan inflasi dengan memproduksi lebih banyak bitcoin.
Bitcoin adalah salah satu dari implementasi pertama dari yang disebut cryptocurrency, pertama kali di deskripsikan oleh Wei Dai pada tahun 1998 dalam milis cypherpunks.

Bitcoin [ Bahasa Inggris ]
Bitcoin is a peer-to-peer payment system introduced as open source software in 2009 by developer Satoshi Nakamoto. The payments in the system are recorded in a public ledger using its own unit of account, which is also called bitcoin.Although its status as a currency is disputed, media reports often refer to bitcoin as a cryptocurrency or digital currency. The bitcoin system is not controlled by a single entity, like a central bank, which has led the US Treasury to call bitcoin a decentralized currency.
Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into the public ledger. Called mining, individuals or companies engage in this activity in exchange for transaction fees and newly created bitcoins.Besides mining, bitcoins can be obtained in exchange for fiat money, products, and services.Users can send and receive bitcoins electronically for an optional transaction fee using wallet software on a personal computer, mobile device, or a web application.
Bitcoin as a form of payment for products and services has seen growth,and merchants have an incentive to accept the digital currency because fees are lower than the 2–3% typically imposed by credit card processors.The European Banking Authority has warned that bitcoin lacks consumer protections.[14] Unlike credit cards, any fees are paid by the purchaser not the vendor. Bitcoins can be stolen and chargebacks are impossible.[15] Commercial use of bitcoin is currently small compared to its use by speculators, which has fueled price volatility.
Bitcoin has been a subject of scrutiny amid concerns that it can be used for illegal activities. In October 2013 the US FBI shut down the Silk Road online black market and seized 144,000 bitcoins worth US$28.5 million at the time.[18] The US is considered bitcoin-friendly compared to other governments, however.[19] The US Treasury has recognized that the bitcoin system is not controlled by a single entity, like a central bank. In China, buying bitcoins with yuan is subject to restrictions, and bitcoin exchanges are not allowed to hold bank accounts.

Satoshi Nakamoto [ Satoshi Bitcoin/Pencetus Bitcoin/Bitcoin Founder]
Satoshi Nakamoto is the pseudonymous person or group of people who designed and created the original Bitcoin software, currently known as Bitcoin-Qt.
His involvement in the original Bitcoin software does not appear to extend past mid-2010.
Identity
There are no records of Nakamoto's identity or identities prior to the creation of Bitcoin. On his P2P foundation profile, Nakamoto claimed to be an individual male at the age of 37 and living in Japan, which was met with great skepticism due to his use of English and his Bitcoin software not being documented nor labeled in Japanese.
British formatting in his written work implies Nakamoto is of British origin. However, he also sometimes used American spelling, which may indicate that he was intentionally trying (but failed) to mask his writing style, or that he is more than one person.
The first release of his original Bitcoin software is speculated to be of a collaborative effort, leading some to claim that Satoshi Nakamoto was a collective pseudonym for a group of people.
Investigations into the real identity of Satoshi Nakamoto have been attempted by The New Yorker and Fast Company. The New Yorker arrived at Michael Clear, a young graduate student in cryptography at Trinity College in Dublin, who was named the top computer-science undergraduate at Trinity in 2008. The next year, he was hired by Allied Irish Banks to improve its currency-trading software, and he co-authored an academic paper on peer-to-peer technology.
Fast Company's investigation brought up circumstantial evidence that indicated a link between an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August 2008, and the bitcoin.org domain name which was registered 72 hours later. The patent application contained networking and encryption technologies similar to Bitcoin's. After textual analysis, the phrase "...computationally impractical to reverse" was found in both the patent application and bitcoin's whitepaper.All three inventors explicitly denied being Satoshi Nakamoto.
