Someone explain to me the point of the bajillion coins out there?
I see all these coins like TRON, devcoin, Eos, etc. and I for the life of me can't understand what in the hell is the point of them. What do you use them for? Why are they nearly worthless? Why on Earth do some coins have billions of coins and are worth $0.00001?? There is a Forbes article saying
TRON has already transcended Bitcoin and Ethereum to become the first smart contract blockchain protocol with over 10 million (m) wallet users in the world.
How on Earth does TRON coin have over 10 million wallet users? Who is using it and why??
Calling on the Core devs to change their PoW algorithm
Summary: I think that it is time for the small-blockian BitcoinCore developers (nullc, pwuille, adam3us, luke-jr, petertodd, etc.) to use their proposed defense against miner attacks: namely, change the PoW algorithm of BitcoinCore so that the ASIC mining hardware cannot be used to mine it. Explanation: Over the last 2 years I have argued many times in the forums, including with several BitcoinCore developers, that a mining cartel with a majority of the total hashpower could force a change of the protocol rules -- such as postponing the next halving for 2 years -- even against the desires of the major holders. After much debating, their arguments against that claim were two. Firstly, they claimed that any such attempt by miners to change the 'consensus rules' would cause all holders to dump their hoards; so that the price would crash, negating any profit that the miners expected to get from it. To that, I counter-claimed that the miners could well get enough public support to sustain the price, to the point that it would be better for holders to openly support it too, rather than oppose it and see their holdings become worthless. However, since that discussion depended on predicting how people would react, neither side was ale to convince the other. Anyway, they secondly argued that, even if the miners did carry out such an attack, the developers would defeat them by changing the PoW algorithm with a hard fork. That would create a DevCoin branch of the blockchain that could not be mined by the existing ASICs. Then all users and holders would shun the CartelCoin branch, and upgrade their client apps to use the DevCoin. The miners would then be left mining a worthless coin, while the DevCoin would prosper on a network of CPUs and GPU miners. Again, I tried to counter-argue that most of the value would remain on the CartelCore branch, with the familiar PoW algorithm and the 1000 PH/s network, rather than on the DevCore branch. But, again, the question depended on predicting human behavior, and stopped there. Well BitcoinClassic -- that, according to the Core devs, is a hostile fork -- already has the support of 70% of the miners. The price did drop a little, but almost certainly because of Mike's pessimistic statements, not because of that "attack". So the first line of defense failed: it looks like the miners will not be "punished" financially for lifting the size limit -- quite the opposite. So, isn't it time for you to deploy the second and ultimate defense?
(NB: typos mine; crappy OCR software. If anyone wants to see the Eliott Wave he's discussing and I'll make it available.) Bitcoin Bubble or Bitcoin Breakthrough? How about both? by Elliott Prechter December 20, 2013 in the Elliott Wave Theorist EWT discussed Bitcoin for the first time in August 2010, when the currency traded at six cents. As far as we know, EWI was the first financial publisher to discuss it. Bitcoin was unknown to the general public and off private investors’ radar. Even the earliest adopters did not take it as seriously as they should have. The most notable example of this is the man who paid 10,000 BTC for a pizza. This pizza purchase is now famous (https://bitcointalk.org/index.php?topic=l37.0), and many continue to track its price in USD terms via the “Bitcoin Pizza Index," which recently hit an all-time high of over S12 million. Fast forward to today, and the currency is regularly featured in financial news and social media. Bitcoin Magazine has become popular, Congress is holding hearings on the currency, Germany has defined its role in finance, China is ruling on its legality, and the business world is adopting it. The most prominent business to embrace Bitcoin is Virgin Galactic, one of the many creations of billionaire Richard Branson (http://www.cnbc.com/id/101220710). EWT readers were prepared for all this. When Bitcoin was still in the shadows, the August 2012 issue said,
Presuming bitcoin succeeds as the world’s best currency-and I believe it will-it should rise many more multiples in value over the years. -EWT, August 2012
The big question on the minds of investors is not what Bitcoin has achieved, but should they buy Bitcoins now? It’s amusing that so many people ignored Bitcoin upon hearing about it in 20 1 0, but now that its price has gone up 20,000 times, they want to invest. Notwithstanding the currency’s potential, this shift in attitude is a signal saying now is not the time to buy. Let’s look at four areas of evidence: 1) Optimism is off the charts. Past issues of The Elliott Wave Financial Forecast discussed people selling their homes and borrowing money to invest in Bitcoins. That was near the peak of wave Now the desire to buy has grown even more extreme. Bloggers are calling for Bitcoin to reach S1 million. . .soon. One young investor borrowed a million dollars from his father and without his knowledge invested it in Bitcoin (https://bitcointalk.org/index.php?topic=359228.0). The other day I walked into a convenience store wearing a Bitcoin T-shirt, and the owner asked me if he should invest now. I felt like I was living in 1929. 2) Investors have recently been rushing to buy a rash of 95 (at last count; see https://bitcointalk. org/index.php?topic=l34179.0) new clones of Bitcoin that have recently emerged: Litecoin, Namecoin, Zerocoin, BBQCoin, PPcoin, PrimeCoin, NovaCoin, FeatherCoin, TerraCoin, Devcoin, Megacoin, Mincoin, DigitalCoin, Anoncoin, Worldcoin, Freicoin, IxCoin... and more. (That they are clones is obvious from the lack of imagination in naming.) This rush of clones is reminiscent of the South Sea bubble of 1720 and the dot-com mania of 1999, when shares of zero-profit, copycat companies (and even fake ones) sold like hotcakes. Virtually every week now, the Bitcoin code is forked into a new coin that investors bid up. lt’s as if buyers feel the world will run out of cryptocurrency, which in fact is infinitely and freely duplicable. 3) The Elliott wave pattern from Bitcoin’s inception shows five waves up. The December ll Short Term Update noted that a major top was potentially in place: The peak [in Bitcoin] came 10 days after U.S. officials, ranging from an assistant attorney general with the Department of Justice to Fed Chairman Ben Bernanke, “spoke approvingly of the potential of virtual currencies." So, here again, the government is getting on board at the very tail end ofa long rise. Since we posted that comment, Bitcoin has fallen an additional 40%, bringing it down nearly 60% from its all-time high. Will this prove to be just another brief, sharp correction or something larger? Take a look at the completed impulse pattern shown in Figure 3. The structure begins very near the inception of the currency three-plus years ago, when it was selling for a penny. Notice that wave @ is a triangle (see text, p.49), which typically comes in the fourth-wave position. Wave a thrust, carried to the all-time high of S 1242 on November 29. The reversal from that point should mark the start of the largest bear market to date in the currency. This forecast is in tune with the anticipated bear market in the broader stock averages, which have strongly correlated with Bitcoin’s pattern. The chart is in log scale to show the returns one would have achieved in each impulse leg of the pattern. Wave Q) achieved a stunning 3 19ox gain. Wave ® achieved 59.3% (a Fibonacci 3/5) of the gain of wave Q). Wave ® (measured from the low of wave @) achieved 39.3% (a Fibonacci 2/5) of the gain of wave (D and 66.3% (a Fibonacci 2/3) of the gain of wave Therefore, while each upward move has been large, each successive wave has been decelerating in log terms relative to past waves, in each case by a Fibonacci multiple. Also notice that Bitcoin trades more like a commodity than a stock, with its blow-off tops and extended fifih waves. Most of the gain since early 20 12 has been within (5) of ® and the final wave all of which is probable retracement territory. 4) Most people involved in this mania seem oblivious to Bitcoin’s fundamentals. In my experience, raising these issues publicly earns scorn for spreading “FUD.” But there is a good reason-now widely ignored-that Bitcoin is beta software. Our August 2010 piece explained how Bitcoin operates, but it’s worth revisiting some details to understand just how out-of-touch investor expectations are with the reality of Bitcoin technology. Specifically, let's examine the limitations of Bitcoin’s blockchain. The blockchain is the heart of Bitcoin. In its simplest form, the blockchain is a public ledger of all transactions that happen in the Bitcoin network. Each block is composed of individual records that track the ownership of each coin. The transactions “fit” together cryptographically. A block is created about once every 10 minutes by the network. Each block is then cryptographically linked to the previous blocks in the chain, forming a history of all transactions that-to Bitcoin’s credit-cannot be forged. To the extent that Bitcoin currency is real, it could be said that the blockchain is the Bitcoin currency. Yet the core problem with the blockchain is that it grows over time and must be shared by every fiill Bitcoin node. Today it is nearing 13 GB in size. Now, 13 GB doesn't sound too large, but at the current rates of exponential growth the blockchain is projected to become over a terabyte in size in just three years. What's more, the amount of accompanying data required to handle just a fraction of Visa-level traffic would overwhelm even the fastest Internet connections. This technical hurdle makes the “Bitcoin is going to a million” commentary seem premature. The hope for Bitcoin’s future lies in its open-source nature, allowing it to be improved, and Moore’s Law. Moore’s Law is colloquially used to signify the exponential increases in computer-hardware efficiency over time, including network capacity. But Moore’s law-which calls for a doubling of computer speed every two years-has hit a snag in recent years: the rate of improvement in performance has dramatically slowed, causing many experts to call for the end of the operation of Moore’s law. (For the record, Moore’s Law was never intended to refer to computer hardware performance, but the media have confused the term to the point where it is now generally used in this context. Originally, it was intended to refer to the increase in the number of transistors that are packed into microchips.) The past four years have been an exciting ride for Bitcoin. But the evidence says the Bitcoin bull market is done for now. It would be best to put Bitcoin out of your mind for the duration of the deflationary wave that is curling toward the financial world. Due to the psychology surrounding Bitcoin, as well as its correlation with the stock indices, it is too risky to buy now. Due to its open-source nature, however, Bitcoin’s infrastructure should continue to improve over the years. For the long run, I agree with Roger Ver, the CEO of memory dealers and one of Bitcoin’s earliest adopters, who recently said, “It is just getting started." But one could have said that about the U.S. stock market in 1966. It would have been visionary only if you were patient and willing to hold through a very deep valley. Our position is that Bitcoin will never again sell for 6 cents, as it did when EWT first wrote it up. But there will be another time to buy it for relative peanuts alongside stocks, real-estate, gold and silver. When the time comes, no one will be interested. Elliott Prechter's primary task at EWI is working on EWA VES, our in-house artificial intelligence softwarefor analyzing Elliott waves.

''' This is my understanding of what you are proposing (correct me if I'm wrong): The idea is to have "adoption-first" group (i.e. big blockers) and "decentralization-first" (i.e. Segwit supporters) group agree to turn the existing single blockchain into two parallel blockchains but without bitcoin token duplication. Using the drivechain idea, the "adoption-first" group would specify a split date upon which they would send their bitcoins to an exit address on Chain A and then only spend bitcoins on Chain B. For the "decentralization-first" group, they may continue to use bitcoin as before. At a later date,Prior to the split date drivechain-compatibility couldwould be added by consensus agreement by Chain A nodes so that members of the "adoption-first" group could release their bitcoins onto Chain A again. Now, the "adoption-first" group can deploy straightforward blocksize increases they would like on Chain B to accelerate adoption with users immediately and possibly never decide to reunite with Chain A again. Likewise, the "decentralization-first" group can continue deploying SegWit, Schnorr signatures, Lightning Network, and other decentralization-friendly optimizations onto Chain A. Big blocker advocates can be encouraged to join Chain B. At a later date, developers for Chain A can add drivechain support so that Chain B users can unlock their bitcoins on Chain A, if they so choose. I'm curious to hear people's ideas on how such a sidechain arrangement could be made an attractive fall-back plan for the "adoption-first" group, especially given the relative simplicity of permitting bitcoin tokens to be duplicated on two blockchains after a hard fork (no need for an exit or reverse migration plan, which is what drivechain seems to facilitate). This is a snippet of [an article]1 about drivechain that I read before I tried to put this summary together:
The gist of it is that to send bitcoins to a sidechain, it's as simple as sending your coins to a particular address, with no added changes of any kind to the bitcoin code itself. Meanwhile, releasing your coins later is harder, and it will take a soft-fork of the bitcoin blockchain. Participating miners will need to download new Bitcoin clients that support this function, enabling the release of these bitcoins. The great news is that no hard-fork is needed, which has a lot of developers relieved. If sidechains are properly implemented, there should be no need for another hard fork, and the associated risks, all forking in the future could be done on sidechains. However, the bad news is that there is an increased possibility for sabotage and perhaps theft. Groups of miners working together can 51% attack a sidechain that they mine, in order to steal any bitcoins that are locked into it. This would, however, only hurt the value of coins on that sidechain, not the original bitcoins. While this is a genuine concern, it is one that Sztorc sees as very close to the same problem bitcoin itself already has, and he claims to have figured out how to minimize the threat, through a process where miners vote to keep things honest. The miners themselves would not have to manually vote, but they would have to merge-mine the sidechain that they can vote on. “If they merge mine, it can all be 100% automated,” Sztorc recently said on Reddit. This means that there aren’t many blockchains that would be compatible with Drivechain's implementation, at least not yet. Scrypt-based altcoins, including Litecoin and Doge, are not compatible since miners of bitcoin can only merge-mine SHA 256 blockchains, like Namecoin, Ixcoin, and Devcoin. This may mean that all sidechains in the future will be brand-new chains, custom created from scratch for the purpose. While sending bitcoins to the sidechain has never been a problem, releasing the bitcoins into the hands of a new owner has been a constant thorn in the side of this whole concept. Drivechain's solution is complex, but far more complete than the Blockstream solution was. Sztorc proposes that whenever you want to change your sidechain coins back to bitcoins again, you send a “withdrawal transaction” (WT) from the alternative chain to a listening address, which destroys the sidechained coins, and specifies the bitcoin destination address. Drivechain Unfortunately, this release process is far from instant, because at this point you have to wait for it to be bundled with other WTs, and wait for the end of a minimum three-day period. This delay could be as much as two weeks, and is designed to give everyone involved the opportunity to ensure that the same WT is in both the Bitcoin blockchain and the sidechain. If the two blockchains disagree, everyone has plenty of time to contact each other, figure out what is going on, and redo the process until they get it right. Drivechain2 The process is obviously more complicated than this, but in simple terms; if there are problems, then a manual solution is available. If there are no problems, then everything proceeds automatically after the minimum three-day wait. There is still quite a lot of coding and experimenting left to do, but the outcome looks sounds promising. Assuming that Sztorc and his team successfully finish, major problems with Bitcoin could be very quickly solved. BitcoinXT, for instance, could be run as an altcoin beside the Bitcoin core client that is mined now, and we could assess which of the proposals is better for bitcoin by watching them. Better yet, a sidechain with a very short interval between blocks could be created. This could provide an exponential increase in the number of transactions per second, creating Visa-like processing capabilities, which would of course greatly increase investor confidence in bitcoin overall. What does this mean for the value of altcoins in the future? It is conceivable that their market caps will all move into bitcoin over time. According to Sztorc, altcoins would eventually become obsolete, at least as far as their price goes. Regardless of the value of any future altcoins, the value of bitcoin could grow substantially once sidechains become a reality, due to all of the added utility. This in turn attracts more miners and further secures the bitcoin blockchain, adding even more utility. A very fortunate positive feedback loop could be started.
edit: integrated luke-jr's reply about integrating drivechain support on Chain A before the split:
We'd need drivechains on Chain A from the start. Otherwise the peg-out to Chain B would literally be an anyone-can-spend on Chain A (or at least a trusted-third-party-can-spend). Otherwise, that sounds about right.
I can't think of exactly how right now (see below for a good idea though), but I want to believe there is a good way to solve healthcare with a p2p trust-based economy using technology, similar to the way bitcoin, that takes out the need for a middle man (the insurance company or even the government). The key is in getting doctors paid, and letting society give back what the doctors need out of free will, rather than by force. One inspiration to look at is Devcoin - they pay writers, software developers and other types of creators in Devcoin. Miners can mine to keep the blockchain strong, but part of the returns the miners receive also go back to pay the creators. The currency can also be traded for Bitcoin and other currencies on sites like Cryptsy.com. I wonder if a "Medcoin" could be created for Doctors that want to give services to patients, the coin itself designed such that a percentage gives back to the Doctors through technology, not by government or insurance company. This, to me, at least the direction of this, is the solution to healthcare. The amazing thing is it won't only solve it in the USA - it will solve it worldwide. Can a cryptocurrency protocol like this generate enough revenue for Doctors to get enough money for their trade? How else can you see a p2p "trust economy" (as I call it) fix the problem of healthcare for all? Could something like this work?
Thoughts on merged mining? (Mining 2 or more coins at the same time)
PoW is intrinsically broken/flawed. We all signed up for it, but I am personally not really that worried. Any new algorithm that relies on PoW is just delaying the inevitable. ASICs are a greater threat than GPU was to CPU in terms of centralization, but if we survive it, we will be much much better for it. How much of a supportive community do we want to be? Will we allow present and future altcoins to use Dogecoin as the parent blockchain and their blockchain is auxiliary? We can't stop them, but it's nice to be inclusive. This is merged mining. You mine 2 or more coins (Namecoin, Ixcoin, Devcoin, I0coin and Groupcoin), at the same time, with one miner. Bitcoin does this all day. Here is a discussion about it for scrypt coins: https://litecointalk.org/index.php?topic=15666.0 At a merged mining scrypt pool that mines Dogecoin, if you had 1250kh/s it would look like this: Parent Blockchain - DogeCoin: You are mining it at 1250Khash/s Auxillary Blockchains: PesetaCoin: you are mining it at full speed, 1250Khash/s UnitedScryptCoin: you are mining it at full speed, 1250Khash/s OrgCoin: you are mining it at full speed, 1250Khash/s HunterCoin: you are mining it at full speed, 1250Khash/s More pools like this would be nice. Is anyone working on a Dogecoin specific one? I would like to think we are the type of community to support this. This could only make us stronger. It's just one of many possible ways to improve our network security.
O bitcoin parece estar em toda parte. Programas de TV aberta, revistas de economia, amigos no Facebook e até outdoors em avenidas “falam” dele (nesse último caso, numa campanha de entusiastas, em São Francisco, nos Estados Unidos). A cotação da moeda virtual decolou de menos de US$ 1, em 2009, para quase US$ 1 mil, nas últimas semanas. O BTC – esse é o código comercial – já serve para comprar quase tudo, de sanduíches orgânicos a viagens ao espaço. Seja ele o dinheiro do futuro ou uma nova bolha especulativa, uma coisa parece certa: a porta que foi aberta, pela qual o mundo enxergou uma forma mais flexível de fazer transações online, não se fechará mais. Um batalhão de novas moedas digitais e tecnologias promissoras já aproveita o embalo para avançar rumo a essa prometida nova ordem monetária. O bitcoin mostrou que é possível existir uma moeda descentralizada, não regulada por governos ou bancos centrais. O mérito de seu criador, uma figura desconhecida que usava o pseudônimo de Satoshi Nakamoto, foi formular um elegante preceito matemático que garante a segurança do sistema. Funciona assim: cada transação é validada por um grande número de computadores de usuários (os mineradores) pelo mundo, de forma que ninguém tenha capacidade de processamento maior que essa rede (para evitar operações fraudulentas). Como recompensa, esses usuários recebem novos bitcoins, que serão criados até o limite de 21 milhões de unidades, por volta do ano de 2140. Além disso, todas as transações ficam registradas numa espécie de lista pública. Entusiastas afirmam que a grande contribuição do BTC foi cultural. Ele uniu uma vasta rede de pessoas interconectadas por uma causa que agora parece ser o futuro inevitável: usar a internet para enviar dinheiro, com menos taxas e burocracia. Se olharmos em perspectiva, ainda que exista essa profusão de seguidores, o bitcoin é coisa de nicho. Para se tornar um novo dólar ou euro, há alguns empecilhos. Primeiro, é difícil de usar. Mandar e receber moedas significa ter de lidar com conceitos como blockchain e public ledger, além de chaves necessárias para cada transação, coisas como 17EC4TXZRzr4UbmrkMc7gUEuCtn73xhTeN. Também existem questões como a alta volatilidade, a suspeita de que milhares de chineses andam especulando com a moeda e, principalmente, os problemas de uso criminoso do dinheiro virtual. O caso mais notório envolveu o Silk Road, um supermercado online de drogas e armas fechado em 2013, no qual o BTC – por permitir anonimato – era a moeda corrente. Por todos esses problemas, o bitcoin pode vir a confirmar uma conhecida tese sobre produtos de sucesso: o pioneiro raramente se torna o líder do mercado. Google, Facebook, Apple e outras empresas vencedoras não inventaram seus produtos – já existiam buscadores, redes sociais e computadores antes. Assim como a Coca não inventou o refrigerante e o McDonald’s não foi a primeira lanchonete a vender hambúrgueres. (Cabe a observação: o bitcoin não foi a primeira moeda digital, mas criou os conceitos que agora são usados por todas as outras, por isso é vista como pioneira.) Como era previsível, várias candidatas já estão no jogo para tentar ser a Apple ou o Facebook dessa teoria. Receberam até um nome na comunidade dos internautas: criptomoedas 2.0 (veja o quadro abaixo). Ainda que nenhuma possa ser declarada vencedora, cada uma expande a seu modo os caminhos para o futuro do dinheiro. “As moedas digitais marcam uma mudança significativa no sistema financeiro, porque são capazes de prover uma cadeia de troca de valores descentralizada”, diz David Furlonger, vice-presidente da consultoria Gartner Group e uma das maiores autoridades em futuro das finanças. “Mas, no momento, nenhuma delas é mais relevante que as outras. O hype em torno do bitcoin é apenas isso: hype.” http://s2.glbimg.com/fIw5bBIj3hFN-RIFMxrKCa_WvC0=/top/e.glbimg.com/og/ed/f/original/2014/03/04/bitcoin-02.jpg Na última contagem do site coinmarketcap.com existiam cem moedas digitais, com nomes como quark, mastercoin ou devcoin. Juntas, somam por volta de US$ 10 bilhões em circulação. Quase todas são versões modificadas do bitcoin. A maioria também usa a mineração digital. Entre as que se destacam está o litecoin (ou LTC). Sua contribuição: pode ser minerada por computadores comuns, enquanto o bitcoin acabou restrito a donos de supermáquinas – o que pode criar distorções no futuro. Assim, o tempo para uma transação ser confirmada cai de dez minutos (no BTC) para dois e meio (no LTC), em média. “Essa segunda geração tem moedas lançadas por companhias bem financiadas e com fundadores experientes, inclusive alguns que participaram da história do bitcoin. O dinheiro graúdo chegou à nossa área, permitindo que mais camadas de segurança e inovação sejam adicionadas”, diz Chris Larsen, CEO do Ripple Labs, que cunhou a moeda digital ripple. O ripple também tem se destacado. Já é a segunda maior em volume circulante (juntas, ela e o BTC formam quase 90% dos US$ 10 bilhões virtuais). Recebeu aportes de investidores badalados do Vale do Silício, como o Google Ventures, o Founder’s Fund e o Andreessen Horowitz. O ripple, na verdade, são duas coisas. É uma moeda baseada em matemática (como o bitcoin), cujo símbolo é XRP. Mas também é um novo protocolo financeiro para a internet. Para entender, vale uma comparação entre dinheiro e e-mails. São os protocolos de e-mail que permitem que um usuário do Hotmail, por exemplo, mande mensagens para um do Gmail, de graça e instantaneamente. O ripple quer fazer isso entre moedas e bancos. Quem cria uma “carteira ripple” pode mandar, por exemplo, US$ 1 mil para uma sobrinha na Austrália com razoável facilidade – e com taxas na faixa de 0,5%. Mas também pode mandar ouro, milhas aéreas, café e qualquer coisa que tenha um valor acordado. Inclusive bitcoins. “Dá para fazer pelo próprio banco, até sem saber que por trás da operação estará o protocolo”, diz Larsen. “Antes do bitcoin, ninguém achava que era possível fazer transações pela internet sem um operador central. Agora o mundo sabe como fazer isso. Mas estamos apenas na pré-história dessa evolução”, afirma. No momento, o protocolo já opera mais de 50 moedas e existem 65 mil contas criadas – número que, segundo Larsen, cresce 7% por semana. Assim como o ripple, outra moeda, chamada next (símbolo: NXT), traz uma inovação importante: ela permite que você adicione novas funcionalidades aos protocolos. Por exemplo, criar contratos. Eles podem servir para executar pagamentos de um serviço, ou fazer operações parecidas com um “débito automático”, mas para a transferência de valores. Como são plataformas de código aberto, permitem que qualquer contrato seja criado, dependendo só da habilidade do programador. http://s2.glbimg.com/x3wY_Vb1vq6T58liOfaY-ADxLWY=/e.glbimg.com/og/ed/f/original/2014/03/04/bitcoin-03.jpg Para mandar dinheiro entre pessoas, protocolos como os do ripple ou do next encontram ordens de compra e venda – como no sistema financeiro – e acham um caminho para mandar o dinheiro. Por exemplo: podem usar ordens de venda de reais e compra de XRPs no Brasil, depois outras de venda de XRPs e compra de dólares na Austrália. “Ele acha o caminho mais ‘barato’ para o usuário, não importa quais moedas serão usadas”, diz Rafael Olaio, fundador da Rippex, a primeira casa de câmbio de ripple do Brasil, prevista para entrar no ar este mês. A ideia de usar moedas digitais para triangular moedas convencionais e permitir o envio de euros ou dólares para outros países, ao que parece, será uma das principais heranças do bitcoin. Outra moeda virtual que aparece entre as mais usadas é o dogecoin, cujo símbolo é um cachorrinho. Assim como o litecoin, é uma filha direta do bitcoin. Mas avança numa direção crucial: sair da obscuridade. Ela é negociada numa casa de câmbio – chamada Cryptsy – regulada pelo Departamento do Tesouro dos EUA. “No caso do ripple no Brasil, para abrir uma conta vai ser preciso mandar RG, CPF e comprovante de filiação. Quero me preparar para quando a regulamentação chegar”, diz Olaio. A regulação, a propósito, é um aguardado capítulo do futuro das moedas virtuais. Ainda que não dependam de governos para nascer, os legisladores podem banir ou restringir seu uso num país. “No Brasil, ainda não há discussão regulatória consistente sobre o tema”, diz o advogado Marcelo Godke Veiga, que acompanha a questão. “O Banco Central sequer definiu se essas moedas serão consideradas moedas. Nos EUA, já existe a decisão de um tribunal de que o bitcoin ‘pode ser entendido’ como moeda.” A aceitação dos bancos será outro momento crítico. “Tenho falado com bancos de diferentes países e eles estão mudando a postura: de ‘avaliando’ para ‘considerando integrar com o sistema’”, afirma Larsen. “Os bancos ainda tentam proteger suas formas tradicionais de mandar e receber dinheiro. Mas terão de se adaptar. No futuro, acredito que eles serão um misto de empresa de tecnologia e de marketing”, diz Furlonger. A Febraban, que representa os bancos no Brasil, não quis falar sobre o tema. Alheias aos bancos, milhares de pessoas usam os dinheiros formados por zeros e uns. Qual será dominante? Talvez nem seja essa a questão. “A grande contribuição dessas moedas é mostrar o potencial da internet para a troca de valores, ainda que se usem as moedas ‘antigas’. Ninguém deve ser forçado a adotar uma nova moeda, nem acho que isso possa acontecer. A ideia importante é usar a internet para trocar valores”, diz Larsen. “O que a ascensão do bitcoin deixou claro é que as pessoas querem mais flexibilidade para mandar e receber dinheiro”, afirma Furlonger. Mesmo se não for a moeda do futuro, o bitcoin pode ter definido o futuro das moedas. FONTE EPOCA NEGOCIOS
Chris Odom and the developers of Open Transactions claim to have built a system which offers truly anonymous digital cash transactions. This is something the bitcoin cannot do at the moment. In a recent Reddit link there was talk of using Open Transactions with BitMessage to start implementing a P2P currency exchange. I have heard a lot of interesting use cases for Namecoin, which is essentially a "peer-to-peer generic name/value datastore system", from user authentication systems, issuing stocks, to a USD backed currency. A good interview on about the system might be Hiro White, if you can get in contact with him on IRC. I'd love to know what new systems are available to use which are based on namecoin or even a intro on how namecoins can be used to create your own .bit domain name. Ripple is the system I know the least about. I have tried to trade for bitcoins with the system, but I feel like I'm using the system wrong, or it is not completed yet. I also wonder about whether ripple is a decentralized or uses a block chain. Is there a spokes person for the project that could explain the system? I also enjoy hearing about any of the other alt blockchains as well including litecoin, ppcoin, devcoin, teracoin, etc.. Thanks! I look forward to more big shows!
What is Devcoin? Devcoin is an ethically inspired cryptocurrency created in 2011 to support open source programmers and writers worldwide. Devcoin is one of the longest running blockchain based digital currencies. Devcoins can be merge mined with Bitcoin or purchased on various exchanges. Basically what I want to g e t across is what is happening in a simple pictorial for anyone to understand that altcoins are being sent to Bitcoin as Newly Generated Bitcoins.
