Title: bitmover Merit Source Application - and thoughts on Brazilian Bitcoin Community
Post by: bitmover on July 23, 2018, 03:04:59 AM
Brazilian Bitcoin Community problem

In Brazil the biggest Bitcoin community is a Facebook group  (https://www.facebook.com/groups/btcbr/)with over 121.000 members .
I think this is contradictory, as Facebook does not respect privacy at all, and all users are there discussing about Bitcoin using their real ID.

On the other hand, bitcointalk Portuguese Local Board is a very small community, with very few active members.

I would like to do what I can to change that, as Facebook is not a good place to discuss about cryptocurrencies.

However, most users in the Portuguese Board are stagnant at their ranks, as many of them are unable to speak English and there are very few merits circulating in the local board. This was already discussed  (https://bitcointalk.org/index.php?topic=4404169.msg39183617#msg39183617)before. I believe the lack of merit is discouraging for new users.
This table by Loganota (https://bitcointalk.org/index.php?topic=4404169.msg39183617#msg39183617) shows the distribution of sMerits in the Portuguese board over time. Starting in 01/25/2018 and ending in 05/25/2018. (couldn´t find an updated one, sorry)

If this situation continues, new users may just leave and move back to Facebook.

I believe that as a Merit Source I can contribute to the local board.

In our local board we lack good technical discussions about bitcoin, however I believe this is not a reason to prevent legit users who are interested about bitcoin to rank-up.

Recently I have spent almost all my sMerits in my local board meriting users which I believe should be allowed to rank up, that are not spammers at all.

Using this tool provided by Piggy (http://albertoit.github.io/), it´s possible to see that I am somehow a link between the local board and the main forum. As a merit source I want to merit both the main forum and the local board posts. As more merit is needed in the local board, I will try to focus there.

Inspired by pugman´s A simple bitcoin Q/A. Learn new and interesting stuff about bitcoin. (https://bitcointalk.org/index.php?topic=2968050.0) I created a similar thread (https://bitcointalk.org/index.php?topic=3336968) in Portuguese Board.




Here is my selection of 10 posts for a merit source application:

* I will post two posts in English first, so this does not get too boring for people who doesn´t speak Portuguese. These are all very good posts which deserved more merits than received.

In the book "Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money", its author (Nathaniel Popper (https://en.wikipedia.org/wiki/Nathaniel_Popper)) quotes a couple of emails sent by Satoshi to other members of the early Bitcoin community. This was apparently right before his disappearance from the forum. Here is the excerpt:

Quote
The author of the Bitcoin software hadn’t posted to the forums since December, but he had continued to e-mail with a select number of developers, including Gavin, Martti, and Mike Hearn, a Google programmer in Switzerland, who got drawn into the project after the WikiLeaks blockade. In late April Hearn politely asked how involved Satoshi intended to be moving forward.

“Are you planning on rejoining the community at some point (e.g. for code reviews), or is your plan to permanently step back from the limelight?” he asked.

I’ve moved on to other things,” Satoshi wrote back. “It’s in good hands with Gavin and everyone.”
[...]
Satoshi’s final e-mails went to Martti, whom Satoshi asked to take full ownership of the Bitcoin.org website.

I’ve moved on to other things and probably won’t be around in the future,” Satoshi wrote to Martti, in early May, before transferring the site to Martti and disappearing into the ether.
[emphasis mine]

Source: https://www.amazon.com/Digital-Gold-Bitcoin-Millionaires-Reinvent/dp/006236250X

I couldn't help noticing that Satoshi announced that "he had moved on to other things" on two different occasions.

What do you think these other things could be? From the context, it sounds these things are unrelated to Bitcoin. Maybe he was working on other projects where programming skills were needed.
This can also be interpreted as Satoshi being more or less satisfied with the development of Bitcoin and confident in its intended future.

I know that this is very speculative and impossible to know with certainty, but I would like to hear your opinion.

In order to calculate how much money do you need to perform a 51% attack on bitcoin:

Current hashrate (Total network hashrate): 36349358,259 TH/S (From https://blockchain.info/stats)

We choose our miners from here:
https://en.bitcoin.it/wiki/Mining_hardware_comparison

Let's take for example: Antminer S9
Hashrate = 14 TH/S
Consumption = 1.375 kW


Cost of harwares:
Hardware = Current hashrate * Price of Antminer S9 / Hash produced by Antminer (per seconds)
Hardware = 36349358,259 * 2400$ / 14
Hardware ~=  6,231,318,559 $

Number of antminers = Hardware / 2400 ~= 2,596,382


Cost of electricity:
Electricity consumption per day = Number of antminers * consumption * 24
Electricity consumption per day = 2,596,382 * 1.375 * 24
Electricity consumption per day ~= 85,680,606 kWh

Electricity cost per day = Electricity consumption per day * Cost per 1kWh
Electricity cost per day = 85,680,606 * 0.045$ (Electricity pricing (https://en.wikipedia.org/wiki/Electricity_pricing) - Depend on countries)


So attacker have to pay 3,855,627 $ of electricity per day !

This without make calculation of transport, renting or buying local where to install all this stuff, without counting the difficulty to get this number of miners and electricity power required to get them working all.

And counting the risk that the attack will not be a success and many other factors ...

If you want to know more about Difficulty and Hashrate: https://en.bitcoin.it/wiki/Difficulty

I made calculation 2 days ago from here:
https://bitcointalk.org/index.php?topic=4429114.msg39597354#msg39597354

In the space of two days, we can see this changes:
Hardwares:
Today = 6,231,318,559 $
2Days ago = 5,936,594,032 $

Difference ~= 294,724,527$
Additional AntMiners ~= 122

Electricity:
Today = 3,855,627$
2Days ago = 3,673,266$

Difference ~= 182,361$

In the current state of things, it's near impossible to attack Bitcoin ! This show how this coin is strong now.

O que é a rede Lightning Network?

-  A Lightning Network é uma rede de canais de pagamento bidirecionais que permitem o roteamento de pagamento entre partes

n?o diretamente conectadas. Cada canal é um smart contract entre duas partes. Basicamente falando, se cria um canal na

blockchain entre os usuários envolvidos, e neste canal é usado para transmitir infinitas transaç?es fora da blockchain

(transaç?es off-chain) entre os envolvidos, tudo isso usando a blockchain para registrar duas transaç?es (abrimento e fechamento do canal)

O que N?O é a rede Lighning Network?

- N?o é e nem fica na blockchain do bitcoin. E n?o é também uma sidechain, pois tem gente confundindo os dois.

E como a Lightning Network (caridosamente apelidada de "LN" e vamos nos referir a ela assim por enquanto, para facilitar o entendimento) pode fazer o bitcoin ficar escalável ?

- A LN Permitirá infinitas transaç?es por segundo por um custo muito baixo, pois seria tudo feito offchain (fora da

blockchain, é como se um nó na rede que voc? fechou um "smart contract" com ele, validassem todas as suas transaç?es e

depois de um certo tempo, ou dias, ele assinasse todas essas transaç?es em uma só na blockchain on-chain). Seria como se um

nó com LN fosse uma operadora de cart?o de crédito que faz transaç?es fora do sistema bancário (as liquidaç?es ocorrem de

tempo em tempo).

Ent?o o que seriam transaç?es offchain?

- Resumidamente, na LN as transaç?es offchain funcionam dessa maneira, realizando transaç?es entre os usuários e usando a

blockchain algumas poucas vezes.

Vantagens da LN?

- Pagamentos instantâneos a anônimos (pois permitiria que só os participantes envolvidos num smart contract LN soubessem da

transac?o, pois nao estaria no blockchain) e poderá escalar a rede bitcoin para um número maior que a VISA.

Exemplo prático de como funcionaria:

- Voc? pode ter apenas um canal aberto com uma empresa ou pessoa, ou seja, uma transaç?o no blockchain, e através deste

canal, enviar milhares de transaç?es, talvez uma para cada produto que voc? compre, e usando apenas a criptografia, a

empresa/ou pessoa teria a certeza de que voc? está realizando pagamento para eles. Tudo isso de forma totalmente segura

usando apenas duas transaç?es que s?o registradas no blockchain. Isso significa que a lightnin network já é capaz nos dias

de hoje de processar milhares de transaç?es por segundo, totalmente de forma decentralizada e transparente.

Existe algo que impera acerca de tudo como uma verdade absoluta, e é que a única certeza que temos na vida é que a morte chegará a cada um de nós um dia. E diante deste problema surgem dúvidas a respeito de como seria possível a herança de cripto ativos.

Pequena história

Fonte: O Globo - 14/02/2018

Há cinco anos, Matthew Moody, de 26 anos, morreu em um acidente de avi?o quando sobrevoava um cânion em Chico, na Califórnia. Seu pai, Michael Moody, sabia que o filho estava minerando bitcoins ? que hoje valem milhares de dólares cada um ?, mas n?o tinha ideia quantos ou como encontrá-los. Michael Moody passou os últimos tr?s anos procurando as respostas.

? Meu filho foi uma das primeiras pessoas a buscar bitcoins. Ele usava seu computador de casa para minerar bitcoins, quando isso era possível, e tinha alguns ? disse Moddy, um engenheiro de softwares aposentado

A natureza descentralizada e desregulada do bitcoin significa que, sem as senhas para ter acesso ? carteira digital do seu filho, instalada no blockchain.info, Moody n?o tem como ter acesso a nenhum recurso. E é quase impossível descobrir se a pessoa tem centavos ou uma fortuna, já que as carteiras podem conter um número ilimitado de endereços únicos ou identificadores aos quais os bitcoins est?o ligados. Sem o endereço, n?o é possível localizar cada uma das moedas digitais.

O bitcoin é uma moeda digital que, até agora, n?o está sujeita a regulamentaç?es de nenhum governo ou banco central. As transaç?es s?o feitas digitalmente, sem nenhum banco para intermediar. Como o dinheiro em espécie, o bitcoin permite que os usuários gastem ou recebam os recursos de forma anônima, ou em grande parte anônima, através da internet. Milhares de computadores no mundo validam transaç?es e adicionam novos bitcoins ao sistema. Existem outras moedas digitais, mas o bitcoin é a mais popular.

Blockchain.info n?o respondeu ao pedido de comentário sobre a quest?o.

? N?o há autoridade ? qual apelar para resolver isso. Essas moedas podem ser abandonadas ? afirmou Nolan Bauerle, diretor de pesquisa de análises de criptomoedas do site da CoinDesk.

Devido a casos como esse que precisamos pensar maneiras de contornar tais situaç?es e uma delas é inovando a maneira de ser feita o inventário e partilha.

Ent?o diante disso, devemos saber primeiramente como funciona e como é feito a partilha.

Como é feito a partilha?

Para ser feita a partilha, o primeiro passo é a identificaç?o da exist?ncia ou n?o de um testamento. Isso vai definir como será parte do processo de partilha.

Inventário e Partilha Extrajudicial irá ocorrer quando:

1° Se n?o houver nenhum herdeiro incapaz

2°Se houver acordo entre as partes

3° Se n?o houver testamento

O procedimento extrajudicial é feito em Cartório ou Tabelionato de Notas, mas vale de qualquer lugar do país.  Esse procedimento é proposto através de uma petiç?o dirigida ao tabeli?o e essa petiç?o tem de ser assinada por um advogado. Essa petiç?o vai ser estruturada indicando quem s?o os herdeiros, quais os bens e direitos e os pagamentos de obrigaç?o do espólio e qual será a partilha a ser realizada.

Inventário e Partilha Judicial irá ocorrer quando:

1° Optar pelo meio judicial

2° Se houver testamento

3°Se n?o houver acordo entre as partes

4° Se houver nenhum herdeiro incapaz

Compet?ncia:

O foro competente é o último domicílio do falecido, ?de cujus?. Se houverem vários domicílios onde estiverem os bens. Se houverem bens em vários domicílio em qualquer um deles.

Objeto:

Est?o sujeitos a inventário e partilha os bens situados no Brasil.

Se houverem bens em outro país tem que ser proposta uma nova aç?o

de inventário naquele país.

Legitimidade:

A legitimidade é concorrente, qualquer das pessoas abaixo pode propor aç?o e se vários deles propuserem simultaneamente vale o que propôs primeiro:

a ? Cônjuge ou companheiro, desde que a época do óbito convivesse com o autor da herança;

b ? O herdeiro que tiver na posse dos bens;

c ? Qualquer herdeiro

d ? Eventuais legatários (aquele que recebeu uma parte da herança por testamento);

e ? Testamenteiro (aquela pessoa no testamento que fica incumbida de dar cumprimento ao testamento);

f ? Credores (do falecido, de qualquer herdeiro ou legatário);

g ? Ministério Público apenas quando houver herdeiro incapaz, se ninguém propor.

Herança de cripto ativos extrajudicial

A herança de cripto ativos da forma extrajudicial acredito que seria inviável, pois como dito acima, um dos requisitos para que ocorra a partilha extrajudicial é se n?o houver testamento, e como está ocorrendo atualmente os herdeiros desses cripto ativos acabam por n?o ter acesso a eles, pois o falecido n?o deixou qualquer informaç?o ( senhas, chaves privadas) sobre a carteira/conta que cont?m esses ativos.

Uma possibilidade que vejo como possível para ser utilizado a via extrajudicial seria que além de ter os requisitos padr?es para ser optar por esse método, seria necessária que o patrimônio desses cripto ativos estivessem em um hard drive, podendo ent?o ser transmitido junto ao bem tangível que o acompanham.

Herança de cripto ativos judicial

Até o momento a maneira mais viável de repassar a herança desses ativos seria pela via judicial, onde o falecido deixaria um testamento indicando um pen drive ou outro aparelho/caderno/local contendo a chave privada ou senhas para acessar a conta que cont?m os cripto ativos.

No testamento iria indicar a quantia total dos cripto ativos e indicar quanto cada herdeiro iria receber, o inventariante ent?o iria deduzir o valor total em R$ pela cotaç?o atual (necessário essa convers?o caso necessite pagar algum credor, pois com a convers?o feita se teria um valor em R$ para se fazer uma média/cálculo), e essa herança de cripto ativos poderia ser repassada como dito anteriormente, indicando dados acerca de como poderia ser acessado esses ativos(senhas/chave privada), ou poderia ser feito através de um smart contract. Nesse caso, o smart contract na teoria já poderia estar pré-constituído para facilitar, deixando a ser preenchido apenas as carteiras (wallet) dos eventuais herdeiros que receberiam esse patrimônio, sendo importante e interessante ressaltar que tais carteiras fossem pertencente a contas criadas em uma casa de câmbio brasileira (Exchange), facilitando a possível convers?o do cripto ativo para R$, para caso venha ser necessário pagar algum credor ou mesmo facilitar para o judiciário, caso fosse necessário tomar alguma provid?ncia.

Vale lembrar que esse método de herança descrito acima vale para os ativos digitais que n?o est?o alocados em hard drives, pois se estiverem alocados em drives ser?o tratados como bens fungíveis, e a transmiss?o deste será feita como se assim fossem.

?Ainda que n?o venha a ser aprovado o Projeto de Lei n? 4.099/2012(legisla sobre a ?Garantia aos herdeiros a transmiss?o de todos os conteúdos de contas e arquivos digitais.?), há a previs?o pelo Código Civil de transmiss?o da herança aos herdeiros legítimos e testamentários, desde logo, uma vez aberta a sucess?o, em seu artigo 1.784. Da interpretaç?o deste artigo, entende-se que podem ser considerados abarcados os bens digitais do falecido, ao menos naquilo que diga respeito aos bens armazenados em hard drives de propriedade daquele, pois viriam junto ao bem tangível que acompanham (o hardware transmitido por herança)? (COSTA FILHO, 2016). Sendo assim, caso os ativos digitais n?o estiverem em sua carteira online por exemplo, mas sim em um hard drive, o qual estaria presente fisicamente na partilha, esse bem irá ser transmitido junto ao bem tangível, tendo a sua partilha como qualquer outro bem desse aspecto.

Problemas na herança de cripto ativos

Um grande problema sobre a herança desses ativos seria se eles estivessem situados fora do Brasil, como iria funcionar a legislaç?o para retirada desse, seria necessário aplicar uma aç?o para inventário e partilha no país situado ou apenas poderia ser retirado enviando de volta para o Brasil, isso seria o suficiente?

Na via extrajudicial ficou claramente demonstrado que devida ? falta de informaç?o que poderia ser suprida pelo testamento, tornaria inviável ou bem mais difícil utilizar esse meio de partilha.

Outra quest?o a ser abordada é, caso todos os bens do falecido tenham se esgotado para pagar seus credores, mas ainda restam dívidas e apenas se tem os ativos digitais no inventário, como seria o procedimento correto e como a legislaç?o brasileira iria se instruir acerca do pagamento desses credores a partir desses ativos.

Soluç?es parciais para transmitir a herança

De modo geral, além das quest?es abordados e meios de transmiss?o de herança indicados na via extrajudicial e judicial, poderíamos ter como meios de transmitir esses bens das seguintes maneiras:

A primeira maneira podemos nos utilizar das carteiras com multi assinaturas, onde que para passarmos a herança e garantir que isso ocorra, iremos distribuir multi assinaturas (Multi-Sig Wallet) entre os herdeiros e uma última em um testamento cerrado. Assim apenas após a morte seria possível juntar todas as assinaturas (herdeiros e aqueles constante no testamento cerrado) e transmitir os bens de acordo com que foi planejado pelo testamento.

A segunda alternativa a ser considerada seria a criaç?o de uma transaç?o nLockTime com data futura e ent?o entregá-la ao herdeiro ou empresa, ou ent?o manter em um cofre familiar, e durante a vida invalidá-la e produzir uma nova regularmente, talvez todo ano no seu aniversário. O herdeiro n?o teria como usar os fundos antes da data acertada e voc? teria liberdade para movimentar os fundos a qualquer momento. Ao movimentar sua carteira/address voc? automaticamente invalida a transaç?o nlocktime.

Mas a soluç?o mais básica seria deixar os cripto ativos em uma ledger wallet por exemplo em um cofre, juntamente com a senha, ou poderia deixar a senha a ser dita no testamento e apenas a wallet física guardada em um cofre.

Regulamentaç?o para herança com conteúdos e arquivo digital

Atualmente n?o há nenhuma legislaç?o regulamentadora sobre tema, apenas tramita o Projeto de Lei n? 4.099/2012, o qual aguarda apreciaç?o pelo Senado Federal, com o intuito de alterar o artigo 1.788 do Código Civil de 2002 para que seja garantido aos herdeiros a transmiss?o de todos os conteúdos de contas e arquivos digitais.

Pessoal, resolvi fazer esse pequeno tutorial aqui porque estou vendo montes de lugares aceitando segwit, mas nenhum deles aceita endereços bech32, que é o padr?o de endereços da carteira electrum. Tem varios tutorias disso na web, mas nenhum em PT-BR, ent?o resolvi fazer o "nosso".

Introduç?o:

O que é segwit?

Segwit é uma alteraç?o no protocolo do bitcoin para permitir a evoluç?o das soluç?es de escalabilidades escolhidas pelo time do Bitcoin-core (e pela comunidade). Ela torna o bitcoin compativel com a lightning network, corrige os problemas de "transaction malleability" e também reduz parcialmente o tamanho das transaç?es, e consequentemente, das fees.

Porque existem dois tipos de endereço segwit?

Quando uma carteira envia uma transaç?o segwit, ela precisa ter certeza que a carteira recebedora é compatível, por isso um tipo especial de endereço que indica que o segwit foi implementado foi criado. Esse novo tipo de endereço se chama "bech32". O problema é que esses endereços n?o s?o compatíveis com carteiras anteriores ao segwit. A maioria das carteiras atuais também n?o implementa esses endereços, precisando de modificaç?es substanciais para passar a aceitá-los. Pensando nisso, criou-se um tipo de endereço "de transiç?o" para o segwit, que nada mais é que um endereço "pay to script" (abreviado como p2sh), igual aos endereços de carteiras multi-assinadas ou de smart contracts, por exemplo. Assim como outros endereços p2sh, os endereços p2sh segwit começam com o digito "3".

Qual a vantagem de usar endereços segwit p2sh?

Hoje, a unica carteira que implementa endereços bech32 é a electrum. Todos os dias s?o anunciados novos serviços com suporte a segwit, mas nenhum deles com suporte a bech32. No brasil, a Foxbit já anunciou o suporte a segwit, mas apenas para p2sh. Lá fora, bitfinex e em breve a coinbase. Nenhuma delas com suporte a bech32. Muita gente (eu inclusive) acha que a electrum colocou o carro na frente dos bois ao implementar bech32 sem ter certeza de isso se tornar um padr?o de fato. Ent?o, hoje em dia, para aproveitar plenamente os beneficios do segwit, é necessário usar um endereço p2sh.

Passo a passo:

  • Crie a seed:
    • O jeito mais fácil de criar a seed é através da própria electrum: Inicie o processo de criaç?o de uma nova carteira e prossiga até o momento em que ele gera a seed. Anote a seed e cancele tudo.
  • Crie uma nova carteira:
    • Abra a electrum novamente. Se vc já tem uma carteira criada, clique em "File" -> "New/Restore" (em portugues, "Arquivo" -> "Novo/Restaurar'). Se vc nunca usou a electrum antes, a opç?o de criar a carteira se abrirá automaticamente.
    • Selecione o nome do arquivo e clique em "Next" (pt: "Próximo")

    (Clique na imagen para abrir a original)
    • Selecione "Standard Wallet" e clique em "Next" (pt: "Próximo")
    https://i.imgur.com/p4eCAPx.png (https://imgur.com/p4eCAPx.png)
    • Selecione "I already have a seed" e clique em "Next" (pt: "Próximo")
    https://i.imgur.com/B9uVVu9.png (https://imgur.com/B9uVVu9.png)
    • Clique em "Options" e selecione "Bip39 seed".
    https://i.imgur.com/j5Ud6Mz.png (https://imgur.com/j5Ud6Mz.png)
    • Vai aparecer uma mensagem onde diz "BIP39 Checksum failed". Ignore essa mensagem.
    • Digite a "seed" anotada anteriormente e clique em "Next" (pt: "Próximo")
    https://i.imgur.com/XI4jVPl.png (https://imgur.com/XI4jVPl.png)
    • Na tela seguinte vai aparecer o "path" de derivaç?o das chaves. Altere o numero "44" para "49". O resultado final deve ser assim: "m/49'/0'/0'". Clique em "Next" (pt: "Próximo")
    https://i.imgur.com/BlK3Evh.png (https://imgur.com/BlK3Evh.png)
    • Entre com a senha para a carteira, e conclua!
    https://i.imgur.com/okgzbYA.png (https://imgur.com/okgzbYA.png)
    • Pronto! Agora vc tem uma carteira p2sh segwit!

    Conclus?o:

    Mesmo n?o tendo uma opç?o direta para a criaç?o de carteiras segwit p2sh, as carteiras electrum tem suporte ao BIP39 e através dele voc? pode gerar a sua carteira e usufruir dos "descontos" do segwit. Crie os endereços e use a carteira normalmente!

What can I do?
If your transaction is under $5000, you can only hope Bittrex will at some point change their cross chain recovery policy (https://support.bittrex.com/hc/en-us/articles/115000961172-Bittrex-s-Crosschain-Recovery-Policy).
Public pressure may help, but ultimately it's the shitcoins that are to blame for using the same address format as Bitcoin. I can imagine exchanges creating an "annual cross chain recovery day", in which they handle all requests from the past year.

Technically, Bittrex can recover your Bitcoins but that would be at a security risk to them as they would have to import the private key for their usdt wallet into another Bitcoin wallet
This explains it nicely (it's about Kraken but Bittrex will use similar security measures):
This is what Kraken replied to me:

"You are absolutely correct about us possessing the private keys in this circumstance. That being said, it isn't as straight forward as you might think. Kraken is a cryptocurrency exchange and the nature of cryptocurrency exchanges are wholly different from the experience you might have with a personal wallet where you have easy access to the private keys. With things like the theft of Mt Gox, the internal compromise of Shapeshift, the social engineering of BitPay, and others, we must put security as the paramount concern. As such, our exchange is setup in such a way that nobody within Kraken can unilaterally move funds. We believe that this is a very important protection that makes it extremely difficult for client funds to be stolen by external or internal parties.

Only a very small group of people at Kraken (devs) have the ability to access your funds given an auditable thorough process of checks and balances. This makes the process extremely resource (time) intensive for the devs that have very full plates and very little time to dedicate to any specific task. They must prioritize all of our tasks internally and the requests of clients as best they can. We think that the prioritization of improving our UI/UX as to avoid these type of mistakes will show the greatest dividends for our clients.

For what it's worth, Kraken made an exception:
In this case we have decided that we are going to make an exception to our general policy of not recovering crypto tokens that have been sent to the wrong address and assist you with the recovery. However, our developers, who are required to recover the funds for you, are very busy at the moment.

We will have to ask you to wait a minimum of 90 days until the recovery can be attempted. These efforts will take time and may not be possible in some cases. We will give you an update only after the recovery has been completed. Please be patient as our team works to resolve your issue.

Tributaç?o

Atualmente no Brasil, a Secretaria da Receita Federal  equipara as moedas virtuais a um ativo financeiro, um bem jurídico com valor de mercado, assim como antiguidades ou obras de arte, nos termos do artigo 25, § 1° , inciso II, da Lei n? 9.250/95.

Entende-se que essas moedas ou ?cripto ativos?, s?o um ativo intangível, pois ele é um ativo n?o monetário identificável sem substancia física, exemplo Bitcoin.

Na publicaç?o da Receita Federal ? MINISTÉRIO DA FAZENDA ? SECRETARIA DA RECEITA FEDERAL DO BRASIL. IMPOSTO SOBRE A RENDA ? PESSOA FÍSICA. PERGUNTAS E RESPOSTAS. Exercício de 2017. Ano-calendário de 2016. Foram feito os seguintes questionamentos:

MOEDA VIRTUAL ? COMO DECLARAR

447 ? As moedas virtuais devem ser declaradas?

Sim. As moedas virtuais (bitcoins, por exemplo), muito embora n?o sejam consideradas como moeda nos termos do marco regulatório atual, devem ser declaradas na Ficha Bens e Direitos como ?outros bens?, uma vez que podem ser equiparadas a um ativo financeiro. Elas devem ser declaradas pelo valor de aquisiç?o. Atenç?o: Como esse tipo de ?moeda? n?o possui cotaç?o oficial, uma vez que n?o há um órg?o responsável pelo controle de sua emiss?o, n?o há uma regra legal de convers?o dos valores para fins tributários. Entretanto, essas operaç?es dever?o estar comprovadas com documentaç?o hábil e idônea para fins de tributaç?o.

ALIENAÇ?O DE MOEDAS VIRTUAIS

607 ? Os ganhos obtidos com a alienaç?o de moedas ?virtuais? s?o tributados?

Os ganhos obtidos com a alienaç?o de moedas virtuais (bitcoins, por exemplo) cujo total alienado no m?s seja superior a R$ 35.000,00 s?o tributados, a título de ganho de capital, ? alíquota de 15%, e o recolhimento do imposto sobre a renda deve ser feito até o último dia útil do m?s seguinte ao da transaç?o. As operaç?es dever?o estar comprovadas com documentaç?o hábil e idônea.

Segundo a Secretária da Receita Federal, a propriedade de moedas virtuais deve ser declarada, anualmente, no Imposto de Renda da Pessoa Física se o valor total ultrapassar o valor mínimo de R$1.000,00, n?o importando se a propriedade adveio de contrato de compra ou de emiss?o originária (mineraç?o, no caso do Bitcoin). Também devem ser declarados os ganhos de capital obtidos na alienaç?o de moedas virtuais com a moeda nacional. Os ganhos ser?o tributados desde que ultrapassem o limite de R$35.000,00. A tributaç?o só ocorre com a alienaç?o, n?o com a simples valorizaç?o da moeda virtual.

Estava vendo aquela série "la casa de papel" e lembrando de diversos posts envolvendo criptomoedas e tudo que eu já li sobre economia, inflaç?o e governo.
Em um dos episódios um dos personagens cita uma compra na deep web por 60 Bitcoins rsrs.
Porém, o que realmente me deixou pensativo foi a fala final do personagem. Ele disse que resolveu fazer a impress?o de dinheiro devido ao fato de que o governo poderia fazer o mesmo (e faz) porém só é crime se alguém de fora do esquema fizer, inclusive deu dados que diziam o quanto de dinheiro os governos injetaram na economia, acabando com o poder de compra dos cidad?os. Poderíamos acrescentar diversas coisas além da criaç?o de moeda que, quando realizada por governos n?o s?o crime, como jogos de azar, esquema de previd?ncia(pirâmide), etc.
Embora seja apenas uma série, fica a reflex?o... Estamos vivendo algo jamais presenciado na história. Isso aqui é história. Conseguimos desenvolver escassez no meio digital.
Devemos sempre nos lembrar do que governos s?o capazes de fazer com nossa moeda, para que, assim, a gente tenha percepç?es do sistema Bitcoin além da variaç?o de preço. Tecnologias est?o sendo desenvolvidas para ent?o usarmos mais facilmente como meio de troca, além da funç?o de reserva de valor.
A reflex?o que fica é: quando pensar em vender seus bitcoins apenas motivado por cotaç?o, lembre-se que o governo tem a máquina de fazer dinheiro, porém eles n?o geram bitcoins do nada. N?o estou falando para nunca vend?-los, porém para termos mais paci?ncia e prefer?ncia temporal mais baixa.
Fiquem ? vontade para criticar e/ou acrescentar algo. Apenas me senti motivado a escrever.

I think anyone can apply to be Merit Source and I'm sure theymos is very objective in assessing Merit Source candidates and its decisions are not based on how many members agree or disagree.

to understand other languages it's very easy by using software Grammarly (premium) it is 90% accurate.

digaran,

1 - I have included English posts because I will, as a source, merit posts in English and Portuguese.

2 - If you look closer, respected users such as DdmrDdmr and xtraelv also merited that Philipino post, as this is a very interesting post. I was mentioned in that post also. So no, I am not blindly handing over my sMerits.

3 - I believe I am a "somewhat" established member. I believe i fulfill all requisites theymos asked. I believe rank is not the most important here, but the attitude and history in the forum.  If not, no problem.

If you want to be a merit source:

 1. Be a somewhat established member.
 2. Collect TEN posts written in the last couple of months that have not received nearly enough merit for how good they are, and post quotes for them all in a new Meta thread.
 3. We will take a look at your history and maybe make you a source.

I am especially eager to have merit sources in sub-communities such as the local sections.

Yes, I’m with you on this one. Not that it should be an issue really, but just to clarify:

 theyoungmillionaire  (https://bitcointalk.org/index.php?action=profile;u=1180530) I believe is on of the best (if not the best) asset that I know of for his local Philippine community and amongst the best posters in general. He tends to make his posts rather useful and directs people to act according to the spirit that is required around here.
As such, he has created multiple guides and has required in the past permission to reference material on his local board. As such, I’ve even google translated the referenced post ( [Filipino Guide] Ang Bitcointalk Merit System  (https://bitcointalk.org/index.php?topic=4544266.msg40904432#msg40904432)) for my personal understanding, and found it indeed meritable. Curiously enough, half of the posts are half in English on that board so one does not really go blindly into that board.

I personally, from time to time, even go to visit other local boards such as the Italian and Portuguese ones, and may have merited a post or two there at some point. It's a challenge to understand different languages to a certain degree, but not too much more that trying to decode many posts placed on the English board (be it for language lack of skills on the author’s side, or specific technicalities which I may not be familiar with yet).

Portuguese board I can sympathise with: they have similar merit ratios as my local board, and only come out a bit better in the ratio merit/post. Nevertheless, the overall daily awarded merit for the board is in the 7 to 8 sMerits region which is not too incentivating from a local board's perspective.

I know our posts are written in Tagalog and it's really difficult to understand for you guys unless you use Google translator but still, you found the worth of my fellows works. I from Philippines as a Filipino appreciates your help. Thanks.

I'm supporting your application and I'm sure you'll be accepted soon. Goodluck buddy.

I fully support this application. I believe that having more merits distributed in the Portuguese section will stimulate the creation of new great topics and posts. Especially unique topics that are not just translations. Moreover, @bitmover has already proved to be a user who constantly produces quality posts throughout the forum and only sends merits to those who really deserve it. We have two other applications of very dedicated people. I hope at least one is chosen.

Today, most of the Brazilian BTC community is, unfortunately, on Facebook. And we are in a constant effort to attract more quality users and companies. We also have a very successful subscription campaign that is exclusive to the Portuguese section

If one of the principal ways of encouraging people is to find good users, with impeccable criteria and the will to help others to be an important part of the forum, then Bitmover should absolutely become a merit source.

As an active member of my local (Spanish) I can see how the forum is kind of centralized, and how for those unable to speak English to rank-up is a really difficult task. That`s why I absolutely believe that merit sources should be implemented in local boards, so the forum can become a decentralized place where everyone has the chance of proving his/herself and to rank-up.

If we want good users to be able to rank up and earn a place in here by their contributions, then local merit sources have a great part and are truly necessaries.
So I support this, I hope Bitmover can become a merit source and help to improve the forum and encourage some good members to continue with their amazing work.

For sure it would be great if Brasil and Portuguese language in general should have own merit source.

I've been to Portugal this year and hope to visit Brasil next year! (Hopefully for crypto-conference, I know there will be one in Spring, as it's always good to combine traveling and crypto-education!)

Bump.

I saw that theymos added some more Merit sources.This is great.

Due to excessive garbage-posting, you now need 1 merit to be a Jr Member. All existing Jr Members who didn't meet the requirement were demoted. Also, newbies can no longer set any signature or personal text.

...
 
With help from DdmrDdmr, I just added 36 new merit sources, which should help newbies achieve the requirement. But if you're incapable of posting anything worthwhile, then you will never rank up, and you shouldn't: this isn't the forum for you.

However, it looks like no merit source was added for the Portuguese Local board. =(

It may be early to tell though. Bear in mind that not all Merit Sources have the same monthly allowance, and there is likely a wide variety as to the amount. I have read that some have seen their allowance increased over time, so perhaps if there were to be one, he/she may become more noticeable as time goes by.

One merit source was added to Portuguese board, but it's not enough in my opinion.

Other boards like the Russian and Indonesian have highly merited users, but Portuguese board does not. Nobody is able to rank up just posting in the Portuguese board.

I received my merit stats from LoyceV a few days ago.
I have been distributing merit in many different boards, most of them in my local board (where it really lack merit sources, and most of the users are stagnant in their ranks since the introduction of the merit system).

I have merited users in 35 different boards, which I believe it is a very nice diversification.

Bump.

I saw that theymos added some more Merit sources.This is great.

Due to excessive garbage-posting, you now need 1 merit to be a Jr Member. All existing Jr Members who didn't meet the requirement were demoted. Also, newbies can no longer set any signature or personal text.

...
 
With help from DdmrDdmr, I just added 36 new merit sources, which should help newbies achieve the requirement. But if you're incapable of posting anything worthwhile, then you will never rank up, and you shouldn't: this isn't the forum for you.

However, it looks like no merit source was added for the Portuguese Local board. =(

This person is not fit for being a merit source. We hope theymos will never allow persons that are low functioning and abuse the trust system like this fool bitmover an opportunity to abuse the merit system like he abuses the trust system.

Strike his application like any other person that knowingly abuses any system of control.

The guy is a complete imbecile. How can such a moronic fool be expected to discern a posts of value from one of complete garbage like his own.

This reply demonstrates you are clearly too low functioning to be a merit source.

You have abused red trust on our account. Show us where we scammed or tried to scam any person out of money? next you claim we "attacked" your with no provocation. That is observable foolish and demonstrates you are clearly too stupid to be entrusted with giving out merit.

If you use a persons own account (that has not scammed anyone or tried to scam anyone out of money ever or been in a scenario where they could of scammed a person out of money) and say you believe their account (and others) should be glowing red as a danger warning to other members as high risk of scamming. You are a fucking imbecile as we correctly pointed out.  Just because you do not like that valid criticism being related to you in those terms, does not mean we are untrustworthy. It actually means we are being direct and to the point (very trustworthy). We are helping you realize you are clearly incorrect, whilst defending ourselves against your attack.

You have demonstrated that you are emotional and will use board metrics for your own political ends.

Instead of trying to debate your side of the argument you just ran crying to red trust with some mental gymnastics that said: I can't argue or debate and prove my point is optimal. So will with no accountability (because others have abused this account before) I will reach for red trust as a political tool. You did not refute or debunk our point. You can not.

No sorry , no imbeciles or those that leave frivolous red trust and then even boast about the abuse ON thread.

If you have no talent or skill to win a debate through reason and logic then you have use as a merit source that should be using reason and logic to discern which posts provide REAL VALUE with regard reaching the optimal opinion or solution.

Playing dumb or in your case being dumb are not the credentials best suited to the merit source position.



NEXT PLEASE !!! No more idiots throwing merit tantrums and merit parties to their pals. Let's reign in merit to the posts that add value in terms of reaching the optimal outcome. Reaching for the systems of control in an attempt to validate or invalidate your own or other persons arguments is the biggest flaw the board still has.

bitmover, he think you abuse trust system because of your negative trust rating which is result of this thread (https://bitcointalk.org/index.php?topic=5153596.msg51443380#msg51443380). If we would interpret the rules literally, then such negative rating should not be given just because we think someone is not trustworthy.

Far away from defending or attacking someone in this case, after all trust feedback is not moderated by anyone - it completely depends on the will of the individual.

Bumping again after some time.

I still think Portuguese board lacks merit sources.
There are many locals such as Indonesian, Russian, Germany, etc where users are able to obtain enough merits just by posting in local boards.

That's not the case of the Portuguese board, where only like 5-10 individuals were able to rank up after the introduction of the merit system

From an objective point of view, the numbers state a potentially contradictory situation on the Portuguese Local Board:

a) On the one hand, the number of Net created posts seem to be picking-up over the past few months (excluding Altcoins for this exercise). Since January 2019, the number of posts has more than doubled, and even tripled during August 2019. Specifically, the Brazilian child board, and the Main board have picked-up a lot of traction over the past few months.

b) On the other hand, the number of merits distributed on the local board is "stable". That is, since January 2019, the number per month is on average 91,5, with it’s ups and downs, but it does not follow the volume of created posts in that same timeframe. Note that September is Partial with data as of last Friday.

Number on Net created posts (see https://public.tableau.com/shared/Q7FJSFDYR?:display_count=yes&:origin=viz_share_link):
  

Number of awarded sMerits (https://public.tableau.com/shared/3885JQQZJ?:display_count=yes&:origin=viz_share_link):
 

Now of course I cannot myself add much subjectivity as to the quality/interest of the posts themselves (that is for locals to point out), or why the surge of the number of posts, but the above could be a pointer that it may be in need of a review.

Disclaimer: Net post are the number of posts created – deleted- moved. Since I cannot disassociate the three concepts, I cannot tell whether a specific set of months have had a heavy contribution to the number due to moderation, lowering the total post count for a given month by means of moderation and not a decrease in organic posting.

-snip-

There's a signature campaign running since 08/aug (https://bitcointalk.org/index.php?topic=5173773.0).. 10 posts/week, 9 members, for sure it helped.


There's a lot of good technical content that deserve more merits

eg
1
Nem todas transações vão confirmar num longo período de tempo. Em 2016-2017 começaram a ser incluídos restrições mínimas no cliente do Bitcoin Core para não retransmitir transações sem taxas por exemplo. Alguns parâmetros são configuráveis mas outros precisam recompilar o cliente, o que raramente quem tem um node rodando vai fazer.
Transações que estão esperando ser confirmadas, são colocadas no "mempool" e podem ser tiradas de lá se o mempool fica muito cheio. Então caso não tenha pressa, é importante:
1. Usar o mínimo configurado de taxa que os nodes vão retransmitir (por default, o Bitcoin Core é 1000 satoshis por kbyte, ou 1 sat/byte)
1.1. Se você configurar o seu node E encontrar outros nodes e mineradores que tenham colocado uma taxa minima menor que isso (mas maior do que 0 sat por kbyte), "teoricamente" você pode ter uma transação confirmada em algum momento.

2. Sua transação precisa ser maior do que "poeira", ou seja o valor do output precisa ser maior do que a taxa necessária para gastar. Isso significa >546 sats para uma transação mais comum P2PKH na configuração tradicional do cliente Bitcoin Core.

3. Você precisa manter um node seu que iniciou a transação retransmitindo a mesma sempre que ela for retirada do mempool. Quando o volume de transações não confirmadas aumenta, as que tem menores taxas são excluídas da maior parte dos nodes. Se o seu node não ficar retransmitindo, a transação some da rede.

Sim, o agendamento é possivel no BTC. Você utiliza um "lock time" e especifica que a partir de tal bloco a transação será válida para ser adicionada na blockchain - basicamente os mineradores não aceitam a transação até chegar no bloco especificado.

Assim, uma transação no dia 03 de dezembro ocorrerá em aproximadamente 15120 blocos, a partir da data de hoje.

Code:
144 * 105 = 15120 blocks  ( número de blocos por dia x números de dias = número de blocos)
590985 ( bloco atual) + 15120 (blocos até o dia 03/12/19) = 606105 blocks (bloco no dia 03/12/19)

Dessa forma, ao especificar um "lock time" para o bloco 606105 e enviar 1 BTC para a Alice a transação apenas será aceita no dia 03/12/2019, data em que a transação será incluída na blockchain pelos mineradores.


O lock time de uma transação poderia ser realizada por meio da edição de uma raw transaction utilizando:
https://live.blockcypher.com/btc/decodetx/
https://blockstream.info/tx/push

SIM - existem dois tipos de transação que você pode fazer:

1. nLockTime: uma transação que só se torna válida após uma certa altura do blockchain (número do block) e alguém precisa guardar a transação e só colocá-la na rede depois que passar esse tempo.
O cenário aqui é: Alice promete transferir para Bob 1 BTC daqui 1000 blocos (~7 dias) e cria uma transação colocando o nLockTime = Bloco Atual + 1000
Bob recebe uma mensagem da Alice com o conteúdo dessa transação assinada e pode colocar ela na rede só depois de 7 dias, para ela ser efetivada.
Se Bob colocar essa transação antes na rede, vai estar inválida/vai ser ignorada.
Se Alice criar uma outra transação reutilizando os inputs da transação que foi para o Bob, quando Bob tentar executar a transação, vai dar errado.
Se alguma coisa acontecer com Alice, Bob ainda consegue receber o 1 BTC daqui 7 dias.

Esse cenário já foi utilizado algumas vezes como um "dead-man switch" ou tipo de testamento onde alguém fica com uma transação no futuro que permite receber seus bitcoins, mas se você quiser, pode mover eles antes e invalidar essa transação futura.

2. CLTV = CheckLockTimeVerify: uma transação que trava os outputs (bitcoins) por um tempo pre-determinado.
O cenário aqui é: Alice promete transferir para Bob 1 BTC *agora* mas que Bob só poderá gastar depois 1000 blocos (~7 dias).
A transação é executada na rede e Bob "recebe" 1 BTC, mas não pode fazer nada para gastar eles antes do LockTime passar.
Alice também não consegue pegar esse 1 BTC de volta.

Você consegue fazer isso usando o Bitcoin Core mas montando a transação na mão (não tem telas para isso).
Não sei de outro client que permite fazer isso com telas...

4
Eu já fiz isso. :)

Pra quem quiser, dê uma olhada no https://coinb.in/#newTimeLocked - você consegue criar um endereço que só permite gastos após X data ou X número de blocos. Coloquei uma data para 6 meses adiante e me forcei um hold.

É um tipo de ataque de "gasto-duplicado" (double spending). Foi teorizado por Hal Finney: https://bitcointalk.org/index.php?topic=3441.msg48384#msg48384 (https://bitcointalk.org/index.php?topic=3441.msg48384#msg48384)

Apenas um minerador conseguiria fazer isso. Porque ele precisa:
1. Ter o resultado de mineração de um bloco, incluindo uma transação que envia bitcoins dele (A) para ele mesmo (B) (sem publicar essa transação na rede). Mas não propaga o bloco novo ainda.
2. Envia uma transação de pagamento com os bitcoins que estão em (A) para algum vendedor que aceite não esperar nenhuma confirmação.
3. Depois que o vendedor aceita o pagamento e entrega o serviço/produto (provavelmente digital), o minerador propaga o bloco novo onde ele invalida a transação que o vendedor recebeu.



6
E um dust attack no qual o montante transacionado é menor do que a taxa?
Para esse precisa modificar o código e recompilar:
https://github.com/bitcoin/bitcoin/blob/master/src/policy/policy.cpp#L14 (https://github.com/bitcoin/bitcoin/blob/master/src/policy/policy.cpp#L14)
Mas ai vc inviabiliza o registro e informações na blockchain, não? Uma operação de op_return transaciona zero alemda taxa.
Não sei se entendi sua pergunta. Uma transação de op_return deixa o output "unspendable"  (= queima), então acredito que ele não precisa ser maior do que "dust" pois não pode ser reutilizado mesmo.

Então, o sabotag3x perguntou:
E um dust attack no qual o montante transacionado é menor do que a taxa?

Num op_return para registro de dados vc vai querer usar o menor output possivel (ou colocar tudo como fee). O "montante transacionado", ou montante queimado no caso, vai ser sempre menor que a taxa (podendo ser até 0).

Entendo que a regra continua a mesma: um *output* válido precisa ser spendable = ser maior que o limite de dust para a transação ser aceita.

Se uma transação quer colocar um OP_RETURN, existem duas opções:
1. faz uma transação com apenas um OP_RETURN, queimando qualquer bitcoin além da taxa (ou colocando apenas o suficiente para a taxa). Isso não gera nenhum output válido, então a transação é aceita.
2. faz uma transação com um OP_RETURN e um output recebendo o valor acima de dust. A transação é aceita porque, dentre os outputs válidos, o valor desse output é maior que dust.

Se tentar fazer uma transação com OP_RETURN E um output abaixo do dust, a transação vai ser negada.

I used https://public.tableau.com/profile/ddmrddmr#!/vizhome/BitcointalkMeritDashboard/GlobalSummary made by DdmrDddmr and made this images

We can clearly see a downtrend in Merit received in Portuguese Local, but not in other locals

Got this data from Portuguese, Spanish, Italian, Philippines and Arabic

I believe those images shows that merit is just gone in local Portuguese board. People were airdropped, then they received 4, gave 2, then received 2, gave 1, and poof, gone.


Sabotag3x alone cannot do much there. I cannot do much as well.
According to the same source, Sabotag3x is the top merit giver with 527 merit. Followed by me (203) and Loganota 146 and Paredao 145.

Even Darkstar_, who just passed by one day, is a top merit giver lol

Just for comparative purposes, Spanish board (which has fewer posts than Portuguese local)
Paxmao 1833
DdmrDdmr  569
seoincorporation 133

Special note for sabotag3x, who was the former merit source of our local session, and had to leave the forum for a couple of months. He is now back. It was hard to outpace him :)
