1701  Other / Meta / Re: Bitcoin Pizza Day - Why old members are no longer active here on: May 24, 2018, 01:46:20 AM
This was one of sole reason for old members leaving the forum.

Some reputed members who left the forum:

sirius
SmokeTooMuch
Gavin Andresen
Mike Hearn
gmaxwell
Vitalik Buterin

and a lot more....

None of them left because of spam or signature campaigns. They left for disagreeing with some questions related to the forum or the Bitcoin project and start to support other forks. Sirius got tired, SmokeTooMuch, Mike Hearn and Gavin Andresen began to support other projects. Vitalik seems to find a greater refuge using Twitter and Reddit.

gmaxwell still uses the forum.

I'm not disagreeing with the premise. I think a lot of others left because of spam. I just put that in these specific cases, they never said this was the biggest reason.

No fim você tem quase os mesmos dilemas das hardware wallets, o fabricante é confiável ? e se quebrar ? e se adulterar ? (até o preço se parece...)
Nao questiono se o fabricante é confiável, ele nao iria hackear seu proprio produto penso eu, isso faliria a empresa, logo nao teria motivos para abri-la. Eu questiono se o PRODUTO é confiavel.
Eu posso falar da LEDGER NANO que ja testei, é totalmente confiável com tanto que o pc utilizado nao esteja infectado.
Se quebrar, temos a seed no momento da primeira configuracao, basta comprar qualquer outro LEDGER e inserir sua seed tudo volta como estava antes.
É possivel fazer verificaçao da integridade do mesmo verificando hash oficial do firmware instalado via python, inibindo assim qualquer alteraçao por um terceiro.

Tava pensando ontem, será que não era mais fácil criar um OS para smartphone que só teria a carteira e nada mais? Dessa forma não dependeria de um computador(quiça infectado) para fazer a ligação.. Na minha cabeça, parece mais seguro, e tem uns smartphones bem baratinhos por ai.. Alguém sabe se alguma empresa está trabalhando nessa área?

Isso seria muito bom. Eu já utilizo um nexus velho apenas para algumas funções, incluindo o authenticator e uma carteira. Instalei o Lineage nele. O login é com um outro email.Um S3 ou Nexus 4 velho tem como encontrar por 100 reais.
Pra PC tem o tails que você pode instalar diretamente num pc só utilizando o pen drive.

Acho que um sistema exclusivo pensando em segurança e utilização pra carteiras seria bem interessante. O principal site para isso é o xda-developers.com. Talvez deve surgir algum por lá em breve.

Shitcoin atacada https://www.ccn.com/bitcoin-gold-hit-by-double-spend-attack-exchanges-lose-millions/

Um minerador conseguiu pegar 51% da hashpower. Ficou com o controle da rede e enviou BTG pra uma exchange e para uma outra carteira. Ou seja, dobrando o que minerou. Retirou da exchange para um outro endereço e reverteu o controle.
1705  Bitcoin / Press / [2018-05-23] Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose Millions on: May 23, 2018, 09:46:07 PM
Source: CCN
A malicious miner successfully executed a double spend attack on the Bitcoin Gold network last week, making BTG at least the third altcoin to succumb to a network attack during that timespan.

Bitcoin Gold director of communications Edward Iskra first warned users about the attack on May 18, explaining that a malicious miner was using the exploit to steal funds from cryptocurrency exchanges.

To execute the attack, the miner acquired at least 51 percent of the network’s total hashpower, which provided them with temporary control of the blockchain. Obtaining this much hashpower is incredibly expensive — even on a smaller network like bitcoin gold — but it can be monetized by using it in tandem with a double spend attack.

After gaining control of the network, the attacker began depositing BTG at cryptocurrency exchanges while also attempting to send those same coins to a wallet under their control. Ordinarily, the blockchain would resolve this by including only the first transaction in the block, but the attacker was able to reverse transactions since they had majority control of the network.

Consequently, they were able to deposit funds on exchanges and quickly withdraw them again, after which they reversed the initial transaction so that they could send the coins they had originally deposited to another wallet.

It is already clear that it is a terrible project. The fact that it is so well valued only shows that the market is completely irrational. I hope this token does the same Bitconect path. Which is moving toward zero.
1707  Alternate cryptocurrencies / Altcoin Discussion / Tari- a new second-layer protocol on MONERO on: May 23, 2018, 06:51:38 PM
The lead developer of Monero has unveiled a new second-layer protocol that will allow users to create and trade digital assets on top of the privacy-centric cryptocurrency’s network.

The open-source project, called Tari, will make it possible to program and issue non-fungible assets like loyalty points, in-game items, and concert tickets over the blockchain. The tokens will function similarly to ERC-721 tokens in the ethereum network (e.g. CryptoKitties), enabling users to take ownership of unique digital assets.

“Tari will fundamentally change the way we interact with digital assets,” said co-founder Naveen Jain. “We are building an amazing team to steward the most useful decentralized platform in existence, empowering anyone to issue, manage, use and transfer their digital assets.”

Though not the first project to use blockchain technology to allow users to trade digital assets, co-founders Jain, Riccardo “fluffypony” Spagni, and Dan Teree claim that it is the first to be optimized for this specific use case, making it ideal for businesses who desire to use it at scale.

Tari will be structured as a sidechain to the main monero network, enabling users to merge-mine its token with XMR.

Spagni, who is also the lead developer of XMR, stressed that this new project will not detract from his commitment to the Monero project, adding that he is stepping back from other professional obligations to make time in his schedule.

He said:

“I’m excited to draw from my experience to build something on top of Monero, and to create a modern digital assets-focused protocol that leverages the Rust programming language. We have the resources to expand Monero’s world-class developer community, and I look forward to launching and stewarding a next generation protocol that is truly useful.”

Tari has received financial backing from a number of venture capital firms, including Redpoint, Trinity Ventures, Blockchain Capital, and Pantera.

I think it would be great if he accepted. Ethereum needs such a move to have a demonstration if it's a decentralized project. The same could happen from time to time with Bitcoin. Have deep changes in who leads the project.

The smaller the power of a small group over the future of a particular project, the better is. And he working on Google would be a fantastic moment to say that Blockchain is the future.

Muito informativo, muito bom o levantamento.

E deprimente ao mesmo tempo, a ideia dos forks no Bitcoin nunca me agradou, apesar da questão dos airdrops... Embarrassed

Até pela quantidade de bobagens desses forks, a começar pelos nomes. Estava lendo sobre os projetos brazileiros e tem alguns que são ainda mais deprimentes. Eles tentam literalmente pegar o código fonte de algum projeto, criar uma estrutura centralizada, reembalar e oferecer colada a um projeto de marketing.

Mas quando oferecem um airdrop, não tem como dispensar.  Grin Tongue

The problem with Bitcoin only exists because people still use electronic fiat. That is credit cards and bank accounts. It is only in the moment of conversion that you are faced with the difficulties imposed by governments.

Paper money is also anonymous. Only at the moment, you need to use a bank is that it happens to be registered in your name. For a long time, the money of some banks in Switzerland were just numbers.

Anonymity will depend on the will of society.

If you do not need to use Bitcoin frequently if your initial idea is just to receive, buy and save I would recommend a paperwallet[1] as the primary device. A tablet is something insanely insecure and fragile. There is a great chance someone else will steal you or it will simply break.

For Ethereum tokens, MEW[2] is the best option, saving the seed in a paper wallet.

Android wallets have as main function to be something practical to use in the day to day. If you still need one, I would recommend Eclair[2] and Coinomi[3].

1716  Economy / Services / Re: [0/15] Receive 0.0025 BTC for your review of a new bitcoin mixer BESTMIXER.IO on: May 21, 2018, 05:33:22 PM
BestMixer code: 2Qui6mcUee

I confirm that I used the service and everything worked correctly. I sent Bitcoin to the designated address and received the correct amount at the estimated time.

I found the site very informative, with more information than the other sites. I think this is very important especially for users who have never used such service. The possibility of using other currencies besides Bitcoin is also something that I do not usually see in other mixers.

Being able to use the site in Portuguese is also a great advantage and something unusual in other services. Another advantage is the ease of using it on the cell phone. Being able to use API also seems to be an important function even though I have not used it.

As for the service, this option of being able to pay a higher rate to use different pools I found interesting. And it seems to offer a lot more privacy depending on the choice. But it is not so clear how much I would lose in privacy using the smallest percentage. Is it too risky? I understood the difference between pools, but I would like some information besides how it works. Also, the information staying in the balloons seems a little bad to use, could stay in the text straight on the page. But I understand that it is an option to simplify the use.

Another note is about time. It could be clearer that the longer the time, the greater the privacy. And most importantly, with no extra fee. If the goal is to send to a cold wallet where the time is not so important, putting a much longer time is a very interesting option at a small cost. In the contact part, it is not clear how this contact is made. How anonymous this communication is.

And because it is possible to save my code, it is not clear if there is any possibility of tracing the source based on these codes. That is, they are saved so I do not receive the address I sent for future use. But could this not facilitate a possible trace when someone has possession of the code?

With this Asian hunt in the anonymous currencies, some exchanges are banning their negotiations, I believe that this kind of service will be more and more useful.

  • Design

I found the site with a beautiful and intuitive design. The page loaded fast and I was able to start using the service very quickly.

  • Information

Plenty of information on how the service works, including a simple video, and what is the need for such a service. I believe they could put some other information on other processes needed to have greater anonymity.

  • Transparency

It is quite clear how the service works since some other mixers may use a different system. I liked that it is clear the option to use a greater time to receive and or pay a higher fee for a stronger service.

  • Mixing Service and Speed

I sent         0.00529524 BTC
I received   0.00518775 BTC

And it took a little over an hour.



If you considered my review good enough, please send Bitcoin to that address. : 1APQhDvKYmPxGrwEepWC7JPcGF7TNWwcWE

Como na teoria você só precisa espetar ele duas ou 3 vezes num computador, isso diminui ainda mais as chances de quebrar. Depois que criou o endereço, não precisa mais utilizar até o momento em que pretende resgatar.


E' falso infelizmente, vou explicar porque: cada vez que o opendime passa por novo dono, ele tem que utilizar o processo de verificaçao que envolve conectar o opendime no USB do computador

Vou dar a minha opiniao: nunca irei utilizar um opendime para armazenar bitcoin, porque infelizmente o custo nao è adequado ao risco falha


Vou me expressar melhor: se o dispositivo custasse 0.5 dolares, daria sim a possibilidade de fazer "notas" de 50 - 100 dolares. Infelizmente com o preço atual qualquer use case sensado nao da certo

Eu vi alguns posts seus lá no tópico com duvidas sobre a segurança, chegou a compra um? Acho que essa questão do preço é o principal mesmo, só seria considerado pequeno dependendo do valor. Igual ocorre em alguns filmes onde numa negociação de milhares de dolares o cara fala no final: "Você pode ficar com a pasta".

Mas ainda vejo vantagem em poder repassar Bitcoin sem precisar acessar um computador seguro. Principalmente em uma viagem. Num Hostel poderia repassar por p2p um determinado valor sem precisar se preocupar com a rede, com virus etc.

Eu já tinha ouvido falar nesse dispositivo um tempo atrás, pelo Fernando Ulrich.
É interessante a idéia, de usar ele como se fosse um dinheiro fisico, fazer uma transferencia de posse, sem passar pela blockchain, mas eu ainda duvido sobre sua segurança, por nao conseguir compreender 100% como tudo funciona.

Me diga uma coisa, ele é um dispositivo eletronico, contem componentes eletronicos, por tanto, sujeito a defeitos.

1-E se por acaso eu coloquei 1BTC nesse dispositivo e o mesmo apresentar defeito depois? Nao reconhecendo mais no usb por ter queimado algum dos componentes ci, resistores, capacitores, controladores? Já que nao temos a chave privada, nem seed, nem nada, entao perdemos o saldo para sempre?

2-Ainda nessa questao de defeito, como garantir, que meu saldo que está lá dentro, será relelado a private key assim que eu acionar o botao do mesmo? Poderia alguem guardar uma quantia, contando que a possui e chegando na hora de usar, simplesmente nao aparecer a private key? Qual o risco disso ocorrer?

3-Na questao de segurança, como poderia ser garantido, que a privatekey gerada, realmente é randomica e nao foi pre programada por hacker que ja a anotou e entregou para ser gerada na mao de outro usuario e assim que cair saldo ele vai limpar esse endereço?
Inclusive, tem um topico de um cara que esta doando essas Opendime, é um tanto estranho essa ação de caridade.

1- Espero que a hardware não apresente esses problemas pelo preço dele, afinal ele foi feito para não precisar de seeds ou backups...

2- Quando você espeta o opendime na entrada usb (com lacre) você tem acesso a um qrcode que seria a sua chave pública, não sei a fundo como funciona o sistema dentro dele, mas isso é "pareado" à sua private key, entao se por algum motivo a private key sumir, você poderá saber sem precisar romper o lacre.

3- O opendime é totalmente aberto, tanto no hardware como software, o que acaba sendo até melhor que a maioria das hardware wallets , que são apenas open source.

No fim você tem quase os mesmos dilemas das hardware wallets, o fabricante é confiável ? e se quebrar ? e se adulterar ? (até o preço se parece...)

 Eu não consegui encontrar algum comentário de alguém cujo dispositivo tenha quebrado ou parou de funcionar quando precisou. Encontrei um :/. Como na teoria você só precisa espetar ele duas ou 3 vezes num computador, isso diminui ainda mais as chances de quebrar. Depois que criou o endereço, não precisa mais utilizar até o momento em que pretende resgatar.

 Mas a questão principal é que o propósito não é ser uma cold wallet. É ser um dispositivo quase descartável, pra dar de presente ou numa transação presencial. Um titulo ao portador. O preço ainda é um pouco alto pra isso, principalmente quando se converte pro Real. Mas acho que o fabricante deve com o tempo tentar diminuir.
