The major disadvantage of all cryptocurrencies versus cash is that without connectivity, they are all completely fucking useless, and therefore worthless.

Can we solve that with Masternode mesh blockchain technology?

I think this should be made to exist. Anyone here know much about crowdfunding?  

Darkcoin. Private. Instant transactions. Works on Mars*

Olá raganius,

Pode explicar mais ou menos como funcionam os masternodes? Pelo (pouco) que acabei de ler, é necessário deixar como garantia em torno de 1000 DRK enquanto o masternode estiver ativo e pela cotação atual isso seria +/- 5 BTC. É isto mesmo? E em caso positivo, já há algum tipo de pool de masternodes ?


Obrigado,


Adriano

a minha expectativa é justamente essa, comprar agora na baixa, segurar e vender la na frente com um bom lucro.

Eh justamente nisso que estou apostando!!!
Aproveitando o momento de baixa pra comprar o maximo de darkcoin. E espero uma grande valorizacao...

Sinceramente ? Acho que não....Se chegar a 5 doletas tem que comemorar...........

Toda abordagem que visa regular o bitcoin é preocupante porque bitcoin é liberdade de expressão, se quem está conduzindo é velho ou novo é irrelevante pra discussão.

Deep Web Bitcoin Mixer’s Recent Hack Restarted The Debate Of Darkcoin Vs Trusted Mixers and Trusted Mixers Won

Recently we broke the story about the online drug marketplaces, Nucleus and Diabolus, adding the anonymous cryptocurrency, Darkcoin. Nucleus and Diabolus were the first online drug marketplaces to accept Darkcoin, and marked a potential new trend for drug marketplaces. The adoption of Darkcoin by the deep web has been one that many Darkcoin investors and users wanted. The adoption of Darkcoin by the deep web would cause a massive increase in Darkcoin’s price, as well as much higher trading volume. A portion of the deep  web community also encouraged the adoption of Darkcoin by marketplaces for the extra anonymity they see the coin providing, over the current de facto currency of the deep web, Bitcoin.

Darkcoin’s Built-In Advantages

One of the many reasons why Darkcoin proponents want Darkcoin to be adopted by marketplaces, over Bitcoin, is the in wallet mixer, or money launder, Darksend. Darksend, if enabled, will mix coins through dedicated nodes on the Darkcoin network called masternodes. These masternodes send the coins through several addresses until the trail is too long for an investigator to search through.

The way people on the deep web currently achieve financial anonymity is by sending Bitcoin through centralized, trusted mixers, BitcoinFog or BitBlender. When trying to achieve anonymity, trusting other people and centralization can be your downfall. People try to avoid centralization for good reasons, illustrated by recent events.

Danger of Centralized Bitcoin Blenders

A day after the Nucleus and Diabolus Marketplace announced their integration of Darkcoin, a medium sized deep web Bitcoin laundering service, called BitBlender, was hacked. This is one of the key reasons why proponents of Darkcoin say that Darkcoin is better. Not only is it automatic but you don’t have to worry about trusting people to properly mix your coins.

BitBlender did come back online the next the day, and admin of the service did try to bandage the wounds by going on to reddit to clear up questions and announce his plans from here. BitBlender’s admin asked the community to be patience, and stick with the service but very few people shared that sentiment. Many users were only worried about getting their money back. Some users reported that they were able to retrieve some of their funds, but many did have the same luck. The BitBlender admin made a statement on reddit detailing the plan to pay people back, saying, “My solution is that I am not going to earn anything of the 1-3% commission as everything is going back to refund the users instead…This is the only way I can think of to be able to return all the bitcoins to the users, if I give up now and don’t try to start Blender again there is no way I can come up with these coins… Then everyone loses!”

Many people were not interested in using the service anymore, though. Many people were even skeptical of the site being hacked and instead suggesting the BitBlender himself stole the coins. Numerous scammers running businesses on the deep web in the past, have said that they been hacked when in reality, they have just ran off with the funds. The deep web community a skeptical bunch when they hear “HACKED!”

Money people had decided to move on to greener pastures when they heard the news. A minority of people voiced their annoyance and disapproval of current way crypto-currency anonymization is done on the deep web and urge the community to get behind the adoption of anonymous crypto-currencies, like Darkcoin. The majority of people ignored this and instead took this as a sign that they use Grams Helix.

Grams Helix – A Bitcoin Blender With History

Grams Helix is a Bitcoin mixer that is run by the same company that got a lot of press for creating the first search engine of the deep web, Grams. While the Grams Helix mixing formula is kept under wraps, he claims that coins you received from the service are not just mixed, but completely different coins from the ones you sent in. Most mixers just send coins through many address, leaving a long trail that is hard to search but nonetheless, leads back to the address to sent the coins from originally. Helix claims to one up this by giving your coins to someone else and some other person’s coins to you. While you will end up with the same amount of coins that you put in, minus the fee, they will not be tied to the address you originally sent to the coins from, at all.

Users still have to trust the admin of Grams Helix and many are willing to do so. The Grams admin has received quite a lot of popularity since bringing the first search engine to the deep web. He is also working on many other services, like a deep web adsense, and a few other projects he is not currently ready to announce. Many deep webbers do have a problem with the fee that Grams Helix charges, which is 3%. Many people hate they have to pay 3%, and wait hours to receive their coins. Others in the community said that is simply the price of being able to mix your coins in a much more anonymous fashion with the Grams brand.

Grams Helix claims they received a huge influx of users after Bitblender’s hack. Nucleus market was still in beta and thus unusable, but Diabolus was operational and made no mention of receiving an influx of new users following the hack. Grams Helix’s service was challenged by the huge influx of users. The Grams Admin made a statement saying, “Since the Bitblender hack , helix has received an influx of new users. This is great news for us but has also kept me and my support staff busy answering emails for the past 2 days.” The users were experiencing a problem the site had never experienced before, expiring Bitcoin address  which were causing a huge problem using the service. A day later, Grams Admin announced they had fixed the problem by allowing users to reset expired addresses themselves. The company also reduced the fee their service charges from 3% to 2.5% for the new users who were victims of the BitBlender hack.

According to posts on reddit, people seem really happy with Helix, despite the premium users pay for using the service. It has been a growing leader in the online Bitcoin mixing business. A few weeks ago, the oldest and most trusted bitcoin mixer on the deep web, Bitcoinfog, was down several hours and many thought the worse, hacked or the admins had ran off with everyone’s coins. Though the service did come back online, in the meantime many were left without a mixer. Many Bitcoinfog users did what BitBlender users did this time, and turned to Grams Helix because of its unique mixing method, and because it offers a faster mixer, called Helix light, which reduces the headache of waiting for your coins to be mixed.

Darkcoin vs Bitcoin Mixers

Even with the addition of the first online drug markets integrating Darkcoin, trusted and centralized mixers are still winning over consumers. While Darkcoin’s Darksend provides anonymity that may be superior, the network effects of merchants, consumers and established markets seems to keep Bitcoin’s position as reigning king secure. While trusted mixers might of won this battle, the war is from from over. Nucleus marketplace just officially opened this week, and Diablous is going strong. The main thing for a markets success is to gather merchants to sell their illegal goods. It has yet to be seen if Darkcoin is going to be enough of a selling point for merchants and attract them to the two sites.

FinCEN’s New Bitcoin Guidelines Actually a Good News
By Forexminute - Yashu Gola | Bitcoin, Cryptocurrency News | Oct 28, 2014 12:49PM GMT



ForexMinute.com – The Financial Crimes Enforcement Network (FInCEN) released new Bitcoin guidelines for Bitcoin exchanges and payment processing companies in the US. The additional rulings stated that such organizations are subjected to fall under the category of money service businesses.

According to the US law, a Money Services Business includes any individual or companies which provides services such as currency dealing or exchange; check cashing; issuing/selling/redeeming of travelling checks, money orders or stored value; money transmission; and US Postal Service. The current working pattern of every Bitcoin payment processing company, as well as exchange, matches with one (or more) service(s) described above, making them liable to be registered as a ‘Money Services Business.’

On March 23rd this year, Bitcoin exchange BitPay had strongly objected for taking its business under such a category, as their services only facilitate transactions between sender and receiver. It doesn’t provide any of the service mentioned under the FinCEN cryptocurrency regulations. Though, an expert view suggests that FinCEN only provides exemption to Bank Secrecy Act regulated institutions, which BitPay unfortunately isn’t.

Worrisome Bitcoin Community
Like every time, Bitcoin community is reacting heavily. One of the first comments over the FinCEN rulings is about its suffocating nature. The comment says that this amendments will certainly make it very hard and expensive to build Bitcoin based products in the US. A rather amusing comment further add, “Leave the USA. Take your bitcoins, business ideas and energy with you. The place is demonstrably sclerotic with entrenched, epic fail. Go West young men!”

Indeed the community is poised to react over any kind of government intervention in Bitcoin. Some leftist sentiment clearly targeted FinCEN itself for its lack of transparency and poor leadership. Some even accused the agency for protecting engrained commercial interests. Though agreeing with their “decentralized” sentiments, we would like point out few good points out of these regulations.

Regulations Aren’t that Bad
In times when the cryptocurrency market is being constantly associated with fraudulent organizations, a stable regulation does no harm, at least to the law-abiding people of America. Instead, FinCEN new rulings gives community the opportunity to weed out bad actors, and bring more clarifying set of investors into the cryptocurrency space.

The only thing that is acting as a major hurdle in the advancement of Bitcoin is lower user adoption. It is only because a common Joe doesn’t trust the virtual currency of any kind thanks to the wonderful examples like Mt. Gox and Moolah. The only way to get rid of such scams in to fall under the government eyes. What’s the point of getting looted and calling the same authorities for help which you once called untrustworthy and manipulated?

What we now see at present is a bunch of immature Bitcoin fans, who are too lost in their anti-government faith to understand the actual benefits such regulations bring to cryptocurrency markets. Bitcoin is not just a trading instrument to short and buy. It was launched as a method to cut off middlemen and make transactions much cheaper than the traditional banking procedures. For a greater public understanding, the community first should maintain the coin’s trustworthiness as a viable trading medium. The overall focus should be on to boss merchant and user adoption at the same pace, which can never be achieved at large scales without trust and “regularization”.

FinCEN rulings, however harsh they may seem, is also a way to see how they are taking Bitcoin seriously. For a coin which was once called a Ponzi scheme by the world’s foremost trading analysts, is ready to share dais with so-called trustable US Dollar. Indeed, you all will have options to enter the cryptocurrency sector via illegitimate ways – much like you download a movie via torrent, rather than buying an original DVD. Regulations will only open an options for you to remain on the safer side. It is up to which way you prefer.

FinCEN Ruling: US Government Ramps Up War on Cryptocurrency
Posted in Digital Currency, News, Regulation By Greg Matthews On October 27, 2014



The Financial Crimes Enforcement Network (FinCEN) today issued two administrative rulings regarding digital currency. And the government has apparently decided to go with the nuclear option.

The first ruling published today relates to the application of FinCEN regulations to a virtual currency trading platform, while the second ruling discusses the application of FinCEN regulations to a virtual currency payment system.

In ruling FIN-2014-R011, FinCEN states that any and all cryptocurrency exchanges must become licensed as a money transmitter including crypto-only exchanges:

As explained in the Guidance, a person is an exchanger and a money transmitter if the person accepts convertible virtual currency from one person and transmits it to another person as part of the acceptance and transfer of currency, funds, or other value that substitutes for currency.

In ruling FIN-2014-R012, the agency confirms that any and all payment processors are obliged to register as money transmitters, significantly increasing the cost of entry in becoming a digital payments provider.

As described above, the Company is an exchanger under the Guidance because it engages as a business in accepting and converting the customer’s real currency into virtual currency for transmission to the merchant. The fact that the Company uses its cache of Bitcoin to pay the merchant is not relevant to whether it fits within the definition of money transmitter.

Once labeled a money transmitter, a business wishing to continue operating must pay hundreds of thousands of dollars to become licensed in each of the 50 states. And that’s only the beginning of the regulatory costs and legal hoop jumping.



In addition, companies are required to register with FinCEN, conduct a comprehensive risk assessment of its exposure to money laundering, implement an Anti-Money Laundering Program based on such risk assessment, and comply with various record keeping, reporting and transaction monitoring obligations, in addition to meeting several other requirements.

It is interesting to note that the government classifies Bitcoin as a digital “property” for taxation purposes, but as a digital “money” for regulatory and licensing purposes.

Do you think Bitcoin can survive this latest atomic bomb blast? Log in below using your favorite social media network and weigh in on the discussion.

Abstract — Bitcoin is a decentralized P2P digital currency in which coins are generated by a distributed set of miners and transaction are broadcasted via a peer-to-peer network. While Bitcoin provides some level of anonymity (or rather pseudonymity) by encouraging the users to have any number of random-looking Bitcoin addresses, recent research shows that this level of anonymity is rather low. This encourages users to connect to the Bitcoin network through anonymizers like Tor and motivates development of default Tor functionality for popular mobile SPV clients. In this paper we show that combining Tor and Bitcoin creates an attack vector for the deterministic and stealthy man-in-the-middle attacks. A low-resource attacker can gain full control of information flows between all users who chose to use Bitcoin over Tor. In particular the attacker can link together user's transactions regardless of pseudonyms used, control which Bitcoin blocks and transactions are relayed to the user and can delay or discard user's transactions and blocks. In collusion with a powerful miner double-spending attacks become possible and a totally virtual Bitcoin reality can be created for such set of users.

Mas só reforçando aqui galera...

Lembro que rolou uma notícia que o governo estava a regulamentar moedas virtuais mas que só se referiam aos processadores de pagamento que mantém saldo em moeda fiat: PayPal, PagSeguro e por aí vai. Toda aquela regulamentação realmente ainda não afeta o Bitcoin não é?

(...)
Art. 6^o  Para os efeitos das normas aplicáveis aos arranjos e às instituições de pagamento que passam a integrar o Sistema de Pagamentos Brasileiro (SPB), nos termos desta Lei, considera-se:
(...)
VI - moeda eletrônica - recursos armazenados em dispositivo ou sistema eletrônico que permitem ao usuário final efetuar transação de pagamento.

BC esclarece sobre os riscos decorrentes da aquisição das chamadas “moedas virtuais” ou “moedas criptografadas”
19/02/2014 17:01

​O Banco Central do Brasil esclarece, inicialmente, que as chamadas moedas virtuais não se confundem com a “moeda eletrônica” de que tratam a Lei nº 12.865, de 9 de outubro de 2013, e sua regulamentação infralegal. Moedas eletrônicas, conforme disciplinadas por esses atos normativos, são recursos armazenados em dispositivo ou sistema eletrônico que permitem ao usuário final efetuar transação de pagamento denominada em moeda nacional. Por sua vez, as chamadas moedas virtuais possuem forma própria de denominação, ou seja, são denominadas em unidade de conta distinta das moedas emitidas por governos soberanos, e não se caracterizam dispositivo ou sistema eletrônico para armazenamento em reais.


A utilização das chamadas moedas virtuais e a incidência, sobre elas, de normas aplicáveis aos sistemas financeiro e de pagamentos têm sido temas de debate internacional e de manifestações de autoridades monetárias e de outras autoridades públicas, com poucas conclusões até o momento.

As chamadas moedas virtuais não são emitidas nem garantidas por uma autoridade monetária. Algumas são emitidas e intermediadas por entidades não financeiras e outras não têm sequer uma entidade responsável por sua emissão. Em ambos os casos, as entidades e pessoas que emitem ou fazem a intermediação desses ativos virtuais não são reguladas nem supervisionadas por autoridades monetárias de qualquer país.

Essas chamadas moedas virtuais não têm garantia de conversão para a moeda oficial, tampouco são garantidos por ativo real de qualquer espécie. O valor de conversão de um ativo conhecido como moeda virtual para moedas emitidas por autoridades monetárias depende da credibilidade e da confiança que os agentes de mercado possuam na aceitação da chamada moeda virtual como meio de troca e das expectativas de sua valorização. Não há, portanto, nenhum mecanismo governamental que garanta o valor em moeda oficial dos instrumentos conhecidos como moedas virtuais, ficando todo o risco de sua aceitação nas mãos dos usuários.

Em função do baixo volume de transações, de sua baixa aceitação como meio de troca e da falta de percepção clara sobre sua fidedignidade, a variação dos preços das chamadas moedas virtuais pode ser muito grande e rápida, podendo até mesmo levar à perda total de seu valor.

Na mesma linha, a eventual aplicação, por autoridades monetárias de quaisquer países, de medidas prudenciais, coercitivas ou punitivas sobre o uso desses ativos, pode afetar significativamente o preço de tais moedas ou mesmo a capacidade de sua negociação.

Além disso, esses instrumentos virtuais podem ser utilizados em atividades ilícitas, o que pode dar ensejo a investigações conduzidas pelas autoridades públicas. Dessa forma, o usuário desses ativos virtuais, ainda que realize transações de boa-fé, pode se ver envolvido nas referidas investigações.

Por fim, o armazenamento das chamadas moedas virtuais nas denominadas carteiras eletrônicas apresenta o risco de que o detentor desses ativos sofra perdas patrimoniais decorrentes de ataques de criminosos que atuam no espaço da rede mundial de computadores.

No Brasil, embora o uso das chamadas moedas virtuais ainda não se tenha mostrado capaz de oferecer riscos ao Sistema Financeiro Nacional, particularmente às transações de pagamentos de varejo (art. 6º, § 4º, da Lei nº 12.685/2013), o Banco Central do Brasil está acompanhando a evolução da utilização de tais instrumentos e as discussões nos foros internacionais sobre a matéria – em especial sobre sua natureza, propriedade e funcionamento –, para fins de adoção de eventuais medidas no âmbito de sua competência legal, se for o caso.

Desculpe a pergunta newbie.

Mas é DRK que tem a opção de deixar a carteira aberta meio que sincronizando, e depois de um tempo você até ganha algumas coins como recompensa?


Caso seja como faço? caso não seja alguem sabe me indicar quais são as coins que fazem isso? E se vale a pena o.o.

Att.

Gostei da parte que fala sobre Satoshi Nakamoto: "um japonês naturalizado norte-americano"... Achei que não sabiamos quem ele realmente era, agora pelo menos já sabemos um pouco mais :-)

Que bom que esse tópico voltou a ativa  

Definição jurídica de bitcoin e as consequências que isso poder ter nos usuários é "preocupante", pois não tem como advinhar os caminhos que o legislativo e o judiciário vão tomar no assunto.

Recomendo a todos a leitura de um aritgo: http://mwilson.jusbrasil.com.br/artigos/146239909/bitcoin?ref=home

É uma análise curiosa e interessante que coloca nossa moeda favorita como uma espécie de contrato. Eu particularmente não gosto dessa definição como colocada no artigo, mas toda discussão é válida nesse meio jurídico!

Por enquanto com aquela decisão da Receita Federal, o bitcoin deve ser declarado no IR por ser considerado semelhante à ativo financeiro. Longe de ser moeda propriamente dita, até justo pelo estado de "Beta" que o bitcoin se encontra.

Lembrando senhores que muito agora é questão de lobby e eventos.

Massificar a divulgação do bitcoin tambem ajuda.

Precisamos saber trabalhar com os politicos com a midia e principalmente com a sociedade em geral.

E justamente esse "valor intrinseco" somado a "utilidade" do Bitcoin que geram a POTENCIALIDADE  para chamarmos de moeda, da mesma forma o ouro, a grama tem a mesma potencialidade.

Na minha humilde opoinião, enquanto estivermos nesse caminho não vislumbro problemas, exceto no caso de (exchange / lavagem de dinheiro), porém se alguem começar a emprestar/pegar emprestado Bitcoin para pagar via R$ (esse vinculo pode gerar problemas).

Por isso eu resumo nisso, que o Bitcoin tem a potencialidade em si, o mercado vai tender ao equilibrio (nunca chegara), mas potencialidade é uma coisa, valor "determinado" é outra.

Fast Food – Criptomoedas e situação jurídica

E o assunto de hoje é sobre a queridinha ancap, o Bitcoin. Pro pessoal que defende as criptomoedas (Bitcoin, Altcoin e tudo mais) e acham que isso é algo aceito ou sequer em limbo jurídico, vejamos o Art. 292 do código penal (que existe desde 1940):

“Art. 292 – Emitir, sem permissão legal, nota, bilhete, ficha, vale ou título que contenha promessa de pagamento em dinheiro ao portador ou a que falte indicação do nome da pessoa a quem deva ser pago”

Não existe jurisprudência, até o momento, porque o Bitcoin ainda não incomodou o governo de verdade, mas a lei já existe e pode ser aplicada quando o governo quiser. Minar Bitcoin é crime SIM. Explicarei a interpretação no final.

No novo código penal (que provavelmente será publicado em 2015 e em vigor em 2016), a lei é ainda mais específica:

“Art. 271. Emitir, por meio físico ou eletrônico, sem permissão legal, nota, bilhete, ficha, vale ou título que contenha promessa de pagamento em dinheiro ao portador ou a que falte indicação do nome da pessoa a quem deva ser pago:
Pena – prisão, de seis meses a um ano.

Parágrafo único. Nas mesmas penas incorre quem:

a) recebe ou utiliza como dinheiro qualquer dos documentos referidos neste artigo;

b) insere ou altera, indevidamente, títulos em meio eletrônico.”

Farei, rapidamente, a análise dos termos aqui:

Emitir é por em circulação, ou seja, efetivamente criar e repassar. No cenário do Bitcoin, a mineração é o ato de emitir. Inclusive, como a descoberta de um novo Bitcoin é divulgada na rede (sistema de conferência), o juiz vai entender (se ele entender), que isso já é o suficiente para configurar o crime. O Bitcoin funciona por meio eletrônico, não tem permissão legal (ou seja, não tem a permissão do BC), conta como título que vale como dinheiro e tem o beneficiário final indeterminado. Encaixa como uma luva no caput do artigo.

No novo projeto, comprar o Bitcoin e usar já é o suficiente para configurar o crime, nos termos da alínea a: Receber ou utilizar COMO dinheiro (substituindo a moeda legal corrente). E lembremos, nossos juízes não costumam entender muito de tecnologia ou de economia, o que vai dificultar ainda mais a vida dos defensores da criptomoedas.

Então, repassando:

Hoje (Código Penal de 40), não é crime usar o Bitcoin, mas é crime minerá-lo.

Pelo anteprojeto atual, usar o Bitcoin (e toda e qualquer criptomoeda ou sequer uma moeda paralela, como o Dolar era usado antes do Plano Real) já se configurará o crime. A pena é relativamente baixa, mas o governo pode vir a aumentar no futuro.

E obviamente, defender a mineração do bitcoin, é incitação ao crime, assim como defender quem minera é apologia ao crime (art. 286 e art. 287).

PS: Fast Food é uma série para textos rápidos e diretos, sem muitas delongas ou análises, que eu julgo importante demais para encontrar facilmente quando necessário e um assunto óbvio demais para precisar de uma análise mais aprofundada.
