Origem: Wikipdia, a enciclopdia livre.

Bitcoin uma criptomoeda cuja criao e transferncia baseada em protocolos cdigo fonte aberto de criptografia que independente de qualquer autoridade central.[3] Um bitcoin pode ser transferido por um computador ou smartphone sem recurso a uma instituio financeira intermediria[4] . O conceito foi introduzido em 2008 num paper publicado por um programador com o pseudnimo de Satoshi Nakamoto que o chamou de sistema eletrnico de pagamento peer to peer.[1][5][6][7]

O nome tambm se refere ao programa cdigo aberto que ele projetou para o uso da moeda e a respectiva rede peer-to-peer que formada. Diferente da maioria das moedas virtuais, bitcoin no depende da confiana em nenhum emissor centralizado, como um servidor de um grande banco por exemplo. A bitcoin usa um banco de dados distribudos espalhados pelos ns da rede peer-to-peer para registrar as transaes, e usa criptografia para prover funes bsicas de segurana, como certificar que bitcoins s podem ser gastas pelo dono, e evitar gastos duplos.

O projeto de Bitcoin permite propriedade e transferncias pseudo-annimas de valores. Bitcoins podem ser salvas em computadores na forma de um arquivo carteira, ou em servios de carteira provido por terceiros; e em ambos os casos bitcoins podem ser enviadas pela Internet para qualquer lugar ou para qualquer pessoa que tenha um endereo de Bitcoin. A topologia P2P da rede Bitcoin, e a ausncia de uma entidade administradora central torna invivel que qualquer autoridade, governamental ou no, manipule o valor de bitcoins ou induza inflao "imprimindo" mais notas. No entanto, grandes movimentos de procura podem fazer com que o seu valor aumente no mercado de cmbio.

O sistema bitcoin depende de transferncias de valores entre contas usando criptografia de chave pblica. Todas as transaes so pblicas, sendo armazenadas em um banco de dados distribudo nomeado block-chain. Para prevenir gastos duplos, a rede implementa um servidor de tempo distribudo, usando a ideia de prova de trabalho encadeadas. O histrico das transaes deve ser armazenado nos banco de dados distribudos (block-chain), e para reduzir o espao de armazenagem so usadas rvores de Merkle.

Bitcoin uma das primeiras implementaes do conceito chamado criptomoeda descentralizada, descrito originalmente em 1998 por Wei Dai na lista de discusses Cypherpunk [8] . Embora tenha apenas formato digital, uma bitcoin no deixa de ser considerada um ativo, no sentido econmico do termo.

Satoshi Nakamoto o pseudnimo da pessoa ou grupo que criou o protocolo original do bitcoin, em 2008, e lanou a rede bitcoin, em 2009. Alm do prprio bitcoin, nenhuma outra referncia a essa identidade foi encontrada. Seu envolvimento no protocolo original parece ter se encerrado em meados de 2010.[10] Antes de seu "desaparecimento", Nakamoto mantinha-se ativo tanto postando informaes tcnicas no frum BitcoinTalk quanto modificando a rede bitcoin. Ele foi o responsvel por criar a maior parte do protocolo, raramente aceitando contribuies de terceiros.[10]

Em Abril de 2011, Satoshi informou a um colaborador do bitcoin que teria "partido para novas coisas".[33]

Vrios jornais, como o The New Yorker e o Fast Company tentaram encontrar a verdadeira identidade de Satoshi Nakamoto. A investigao do Fast Company insinuou haver uma ligao entre uma patente de criptografia requisitada por Neal King, Vladimir Oksman e Charles Bry no dia 15 de agosto de 2008 e o registro do domnio bitcoin.org, feito 72 horas depois. O pedido de patente (#20100042841) continha tecnologia similar do bitcoin. Ao menos uma frase idntica foi encontrada tanto no pedido de patente quanto no documento descrevendo o bitcoin. Os trs homens envolvidos na petio de patente negaram explicitamente serem Satoshi Nakamoto.[34][35]

No dia 12 de maro de 2013, um servidor bitcoin (tambm chamado de "minerador") rodando a verso mais recente do protocolo criou um registro grande demais no log de transao (tambm chamado "blockchain"), incompatvel com verses anteriores do protocolo devido ao seu tamanho. Isso criou uma diviso no log de transaes. Alguns usurios utilizavam a verso mais recente do protocolo, compatvel com registros mais longos, enquanto outros usurios ainda utilizavam verses mais antigas do protocolo, no utilizando o log novo, grande demais. Essa bifurcao resultou na formao de dois logs diferentes sem um consenso de qual o log definitivo, o que permitiu que um mesmo valor de bitcoins, representado em dois logs distintos, fosse utilizado duas vezes. O site Mt.Gox temporariamente deixou de aceitar novos depsitos de bitcoins.[36] A cotao do bitcoin caiu 23% para US$ 37 no Mt.Gox, retornando cotao anterior de US$ 48 aps algum tempo. [24][25]

Bitcoin firm goes dark, and funds are missing

Bitcoin is again drawing scrutiny following an apparent theft of $387 million in client funds from a Hong Kong exchange that trades in the virtual currency.

Hong Kong police are reportedly investigating the disappearance of the money at MyCoin, which allowed users to buy and sell Bitcoin. The company appears to have suspended its service. Calls to MyCoin could not be connected, while calls to its customer service line were not answered, according to Reuters.

In wake of the incident, Hong Kong's central bank cautioned consumers against investing in virtual currencies.

"Authorities are fumbling around trying to regulate these things," said Steve H. Hanke, a professor of applied economics at The Johns Hopkins University and a senior fellow at the Cato Institute. "Hong Kong has a very good, regulated banking system. It does not want the authorities in Beijing coming down on them hard because something happened in some Bitcoin exchange."

But the latest cloud over Bitcoin, and the largest since the 2014 bankruptcy of Tokyo-based Mt. Gox exchange, has less to do with the pros and cons of using or investing in virtual currencies and more to do with an old-fashioned scam.

"Reports say this wasn't a traditional exchange that was hacked, like Mt. Gox, but instead a business that provided some sort of contract that promised you a return, and some are surmising MyCoin was really running a Ponzi scheme based on Bitcoins," said Reuben Grinberg, an attorney at Davis Polk & Wardwell who started writing about the digital currency in law school.

"Oftentimes with new technology, where regulators haven't clamped down yet, scammers or people with bad intentions come in and start harming investors," said Grinberg, who cited as example the U.S. Securities and Exchange Commission action last year against Trendon Shavers and Bitcoin Savings and Trust, or BSCST, the online entity he created.
