Updating merit data of local session since I became meirt source:



And here are the top merit senders of our local board:



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 Smiley

bumping my thread for visualization.

I am still second top merit giver in Portuguese board, behind our only merit source. I have very few sMerits left.

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)

There's a signature campaign running since 08/aug.. 10 posts/week, 9 members, for sure it helped.


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

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...

Eu já fiz isso. Smiley

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://bitcointalksearch.org/topic/m.48384

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.

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
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.

There are lies, damned lies and statistics. MTwain
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.

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

bitmover, he think you abuse trust system because of your negative trust rating which is result of this thread. 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.

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.

I abuse the trust system? My trust is 0-0-0  Cheesy
Please tell me where and how I am abusing the trust system. Show me how am I getting any benefit from this abuse.

Show my merit abuse please.

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.

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.

I @cryptopreneurBrainboss endorse @bitmover. I believe he's worth/deserve to be a merit source. Theymos when appointing new merit source bitmover should be consider he's application (quoted posts)  are merit worthy and his application has been active for over 7months now still he didn't give up hope. He should be given a chance to assist the other merit sources highlight quality post through meriting them.

Bump after some months.

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.
