Cat Philosophy, River Philosophy and Non-debate theory

Hey, Let me start by saying that I don't like the idea of the Infrastructure funding proposal, and that part seems obvious for many people. I share this sentiment. There would be no better way to put it, in my opinion.
The first paragraphs of Jiang's post along with some comments made me upbeat, and I had to stop before finishing it. This to say that initially I was in a "oh wow" state.
Further reading left me I don't know exactly how. I've been happy, calm and hopeful with the 'state' of Bitcoin Cash and it took that away from me. No where to turn, at the time.
and with this sentiment, and with this from usetodu, and the post from useMortuusBestia. Opinions convoluted. Nothing made sense.
"I don't agree but I must comply if I want to keep participating where a very considerable part of the hashpower is." Paraphrasing my thoughts some time ago. I could understand around this time that maybe, "This must be how miners feel", several times under different regimes, Core and Blockstream, communism and dictatorship where they are from, happening with all their people around, family, friends, peers. And we are the ones they can turn to. If it's true we must understand this point. As an aside, i saw the video where Jihan Wu was talking about the takeover of Blockstream, quite some time ago and how it happened., specially at minute 7m30s. We were there together.
Make the money, don't let the money make you.
As I see in the horizon, there is one way, and one way only, if this madness is to go through, to separate "O Trigo do Joio" how you say in portuguese. Sorry to bring religion here. I am here until the end, be it no hash, or crossing the river.
I found quite interesting the original post by Jiang Zhuoer. I wonder why he censored himself, he should have not done that, we are here together.
So, to separate the 'wheat from the tares', let's see if I can explain it. Infrastructure funding is long term, very long term. that's what we suppose is what we want and are doing, to make peer to peer cash for the world. Amaury also said that popping in and out does not make it, only commitment. It's quite simple: I will consider the Funding Proposal, no matter how many Millions, Billions, Trillions, Peta or Exahashes per second you guys have, if and only if there is a clause that makes the funds spendable in ten years from now. Six to ten years. No Debate.

Palavras mais frequentes nas descrições de mais de mil comunidades
Esta nuvem de palavras é produto deste novo código que combina exemplos de utilização de word_cloud; a necessidade desta abordagem se motivou justamente pela dificuldade de encontrar maneira mais apropriada para tratar o conteúdo das descrições dos subs (objeto da primeira coluna informativa tanto no site quanto no aplicativo) devido à excessiva quantidade de caracteres e ao limite de caracteres do Reddit; isso também justifica a demora entre a última postagem e esta e, por isso, a documentação do repositório e das wikis será atualizada em breve.
Os dados foram obtidos hoje do mesmo modo que foram coletados anteriormente, mas lidamos agora com informações frescas de 1.109 subs lusófonos e afins; do todo, foram retiradas somente as descrições de cada sub que foram juntadas e processadas pelo gerador de nuvem de palavras por frequência removendo uma série de palavras filtradas (pronomes, preposições, artigos, conjunções, advérbios, verbos auxiliares de tempo, letras do alfabeto, algarismos romanos além de algarismos indo-arábicos e símbolos removidos do texto com ajuda de expressões regulares); o tamanho da fonte e as cores indicam a frequência das palavras no conjunto de descrições.

Why u think dark taxi and big dogs left and only partysquadNL( safe in Netherlands embassy) is existing after hansa market trojan task operation..the big dogs already knew u morons
deepdotweb our supposed savior ... posted 10 new markets over night just in time for ,operation final kill , nightmare is super new and being heavily promoted on there own dread and wallst mods , open ur eyes !!

the comments to keep using wall st ...to the update on there own site to say " it was jus maintenance" ( it was jus being rooted) ...
EVERYTHING is for operation final kill , u fuckin trade there credit cards and push fentanyl and even fuckin Carfentanil , good riddens , out of the ashes will be designer markets ....get out while u can

call this fud if u want , theres a reason all the old g's in the game are long gone into the shadows..

remember how they took over hansa and alpha and used hansa as a trojan horse, they destroyed it from the inside out
direct deals and wicker is the future, the new cats are already on it , they will make a name ..and then dissapear like loki2.0 on vacation or that one acid guy everyone used, more trust then using these markets, currently...

dream is rooted but the fail safe was activated, thus needed all the vendors and saps ,to move to the honeypot for sapping....

dream owner is the ONLY guy in the whole equation !! smarter then u and me and cia

u have become enough of a problem where DEA and CIA and euroPOL has joined forces, fuckin selling guns and things 1000x stronger then heroin to mankind ...north korean secret channels hacking bitcoins and creating super counterfeit 100 dollar bills to destroy western culture and there economy.....

hahah silent 0sec pre manufactured exploits on that " move the mouse to a certain point of the message and u been dll hooked level "


its there own technology , u morons ...tor is developed by who? wiki it please ....

they can see u from mars , from ANY vpn to TOR to KFC to whisper app....its jus toys to them..from pizza hut to that xbox 360 in iran to Saddam in a underground hole to ur simple tor exit's ...to the camera in your phone and xbox kinect...to depths of the ocean ;
EVERY company from Microsoft Facebook to google to apple to reddit to youtube to whatsapp has back channels designed for them, they unite under one umbrella to protect western interests ...they are GOD , nsa and europol ..how u think they get the coordinates of the terrorists for there daily drone strikes, u never seem to hear about anymore :-)

they hire the best of the best who sleep with the best...
if u want to continue using major markets that popped up over night, go ahead bro...

wikipedia : Streisand effect ...

u infect the staff then the admin....scam the customers , then u change there beliefs in markets ...then u scam the new comers some more..wash repeat in few years , markets will be all gone..works muchhh better then the seized sign
pt 1 expose:
https://www.reddit.com/darknet/comments/bh4q1v/the_real_reason_all_the_markets_seem_to_exit_dont/

What if Wikipedia started accepting dogecoin for donations?

Just searching something random on wikipedia then i saw that they are asking for donations and this shibe looking for way to help just noticed that they only accept paypal or credit card?
That is so old school! Then i thought what if it had a dogecoin button like this image?
Let´s ask them to start accepting dogecoin!! Who is with me? To the moon!

Blockchain nas urnas eletrônicas

Não sou da área de TI, mas tenho lido muito à respeito das blockchains, sistema de confiabilidade das informações em uma rede. Se há, hoje, uma comoção tão grande em relação ao uso da urnas eletrônicas, a verificação da validade dos dados através de blockchain não seria uma saída viável? Não tornaria crível, e ainda melhor, inquebrável o sigilo da urna eletrônica?
Posso estar falando besteira, mas me ocorreu isso hoje...
https://pt.wikipedia.org/wiki/Blockchain
https://tecnoblog.net/227293/como-funciona-blockchain-bitcoin/
Sei lá, acho meio bizarro que existam pessoas que preferem voltar a usa cédulas de papel do que evoluir uma tecnologia que nós criamos e é pioneira no mundo.

Um Pequeno Resumo Sobre Criptomoedas

Não vou me delongar muito no assunto porque isso é o Reddit e ninguém quer ler uma dissertação de 5000 palavras. Mas vou começar explicando a história, motivo e vantagens. Depois vou passar para as desvantagens, evoluções e por fim o cenário atual.

Criação

Bitcoin não é novidade, foi criada em 2009 por um anônimo que respondia pelo nome de Satoshi, por isso alguns pensam que é uma criação japonesa (mas talvez o cara seja simplesmente um fã de Pokémon). Curiosidade: a carteira original de Satoshi ainda possui 8% de todas as Bitcoins do mundo. A ideia de gênio do Satoshi foi de criar e implementar uma tecnologia chamada Blockchain para criar uma moeda virtual descentralizada e segura. Esta tecnologia basicamente consta da ideia de que cada "usuário" mantenha uma cópia de todas as atividades feitas nesta rede virtual (transferências e criações de moedas), isso garante que uma pessoa não possa, por exemplo, simplesmente inventar 5.000 bitcoins e mandar pro amigo. Leia mais sobre a blockchain aqui.

Vantagens

Esse já é um assunto bem disperso em redes mainstream, mas as vantagens são a descentralização (não dependência de nenhum governo), segurança (apesar de algumas falhas já terem ocorrido) e anonimato. Isso é interessante pois cria uma unidade de valor "estável". Ou seja, em seu status de unidade de valor, o bitcoin se assemelha mais ao ouro do que a moedas de países. Mil reais brasileiros podem nem existir daqui a 100 anos, mas uma barra de ouro ainda vai ser uma barra de ouro e um bitcoin ainda vai ser um bitcoin. O valor pode flutuar, mas a unidade é a mesma. Esta é a primeira geração de cripto-moedas: Bitcoin e suas cópias.

Problemas

Lerdeza: Bitcoin é extremamente lerda. Possui uma taxa média de 7 transações por segundo. No mundo inteiro, 7 transações por segundo. Eu não sei se fica claro somente com esta informação, mas possibilitar apenas SETE transações por segundo em uma rede que deseja ser utilizada mundialmente é risório! Atualmente existem mais de 300.000 transações na "fila de espera", e o tempo para a transação ser efetivada pode chegar a durar mais de um dia! Isso também acarreta outro problema: taxas. Quanto maior a fila, maior a taxa para que sua transação não fique perdida (transações com taxa maior são aceitas primeiro)
Armazenamento: Devido ao crescimento exponencial da quantidade de transações (lembrando que todas as transações são armazenadas na blockchain, como visto em CRIAÇÃO), o tamanho da blockchain também está crescendo exponencialmente. Atualmente já bate 139 gigas de tamanho, e brevente esse número será tão grande que usuários com máquinas normais (sem ser servidores gigantes) não poderão armazenar a blockchain inteira, que é um dos pilares da descentralização da bitcoin.
Escalabilidade: Tendo em vista os dois problemas acima, percebe-se que a Bitcoin não está preparada para ser usada mundialmente no dia-a-dia de todos. E o pior é... Não tem previsão para melhorar! Por isso muitas pessoas que acompanhavam o projeto há anos estão abandonando o navio.
Estes são os três maiores problemas que a bitcoin sofre atualmente (na minha opinião), e infelizmente não são os únicos...

Avanços

Com os visíveis limites do bitcoin, um grupo de desenvolvedores começou a criar uma nova criptomoeda... Mas dessa vez ela seria inteligente! Você poderia pagar fulano SE recebesse o produto. Você distribui uma parte do dinheiro CONFORME a pessoa contribui com a rede, etc! Essa é a ideia por trás dos contratos-inteligentes (smart contracts) que é o carro forte das moedas como o Ethereum.
O Ethereum iniciou a "segunda geração de criptomoedas". Com ela vieram inúmeros clones, a grande maioria das moedas atualmente no mercado são clones do Ethereum com uma pequena modificação. Alguns problemas da Bitcoin foram atenuados, mas nenhum deles realmente foi resolvido.
A taxa de transações por segundo duplicou... Para míseras 14 transações por segundo. A segunda geração abriu inúmeras portas para a aplicação da blockchain em diversos tipos de aplicações, mas não resolveu os problemas que atingiam (e ainda atingem a bitcoin).

Cenário atual

Com a popularidade da bitcoin deixando a Beyoncé para comer mosca, a busca pela moeda e interesse só vem aumentando. Com isso o mercado está valorizando absurdamente, mas bem instavelmente também, com correções de preço de até 40% de um dia pro outro.
Porém, pela terceira vez que falo nesse post: os problemas ainda não foram corrigidos.
Então é isso? Está tudo fadado ao fracasso? Não!
Atualmente estão surgindo os primeiros projetos que estão tentando ser "a primeira moeda da terceira geração". Essa terceira geração seria uma cópia da segunda, porém com os problemas resolvidos (entre outras coisas). Essas moedas são principalmente IOTA, EOS e o que eu particularmente estou interessado e investindo: CARDANO !.
Espero que este post tenha sido uma introdução boa ao assunto! Caso tenha alguma dúvida (e eu saiba responder) pergunte a vontade!

modulo WWW::Mechanize

E ae galera beleza? nesse tutorial vamos brincar com o modulo WWW::Mechanize do perl, esse modulo nos permite fazer determinadas requisições em sites, manipular parametros e metodos passados, manipular formularios daquela pagina, manipular os cookies e headers da requisição e etc. Com esse modulo é bastante simples o desenvolvimento de bots, scripts voltados a coleta ou dump de informações em sites, ou simplesmente automatizar um determinado envio de formulario pela web. Normalmente o modulo não vem instalado por padrão, uma das formas de instalar ele é utilizando o CPAN
sudo perl -MCPAN -e "install WWW::Mechanize"
com o modulo instalado basta a gente declarar ele no nosso script para começar
#!/usbin/perl use WWW::Mechanize; 
agora podemos instanciar um objeto desse modulo, no caso WWW::Mechanize
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; 
com o objeto instanciado, é possivel fazer uma simples requisição GET em um determinado site usando o metodo get e passando a url como argumeto
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("http://eofclub.in/"); 
para exibir a resposta usamos o metodo content
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("http://eofclub.in/"); print $kodo->content; 
![https://i.imgur.com/Jj1CIxA.png](https://i.imgur.com/Jj1CIxA.png)
usando regex podemos recortar trechos especificos e montar a saida como a gente desejar
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://steamcommunity.com/id/$ARGV[0]"); my @mensagem = $kodo->content =~ /meta name="Description" content="(.*?)"/si; my @amigos = $kodo->content =~ /friendBlockContent">(.*?)
/gis; my @online = $kodo->content =~ />Last Online (.*?) ![https://i.imgur.com/uXatz0H.png](https://i.imgur.com/uXatz0H.png)
é possivel retornar o codigo de status usando o metodo status (passamos o autocheck para o objeto para continuar executando mesmo com o erro)
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize(autocheck=>0); $kodo->get("http://google.com..b"); print "codigo: " . $kodo->status . "\n"; if($kodo->status == 200){ print "tudo sussa!!! \n"; } else{ print "vish deu ruim \n"; } 
com o metodo uri retornamos a url atual
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize(autocheck=>0); $kodo->get("https://dolarhoje.com/bitcoin-hoje/"); print $kodo->uri . "\n"; 
com o metodo links é possivel retornar todos os links daquela pagina como uma array, podemos utilizar o parametro url para especificar as urls dos links e o parametro text para os textos naqueles links
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://pt.wikipedia.org/wiki/Perl"); my @links = $kodo->links; foreach my $l(@links){ print $l->text . "\n"; print $l->url . "\n"; print "=========================\n"; } 
![https://i.imgur.com/KpCsFlT.png](https://i.imgur.com/KpCsFlT.png)
o metodo images retornamos as imagens da pagina
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://www.facebook.com/forumeof"); my @img = $kodo->images; foreach my $i(@img){ print $i->url . "\n\n"; } 
para retornar informações dos formularios naquela pagina usamos o metodo forms, podemos usar alguns parametros como o action para onde sera redirecionado aquele formulario, o method sendo o metodo usado
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://youtube.com"); my @formulario = $kodo->forms; foreach my $f(@formulario){ print $f->action . "\n"; print $f->method . "\n"; print "------------------\n"; } 
podemos usar o metodo inputs no exemplo anterior para retornar todos os inputs de cada formulario, com o paremetro type retornamos o tipo de input (text, password, hidden, button e etc), com o parametro name retornamos o name que sera passado, com o parametro text o texto no input, com o parametro value o valor pre-definido dele
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://youtube.com"); my @formulario = $kodo->forms; my @inputs; my $i; foreach my $f(@formulario){ print $f->method . ": " . $f->action . "\n"; print . "\n\n"; @inputs = $f->inputs; foreach $i(@inputs){ print "----------\n"; print "type: " . $i->type . "\n"; print "name: " . $i->name . "\n"; print "text: " . $i->name . "\n"; print "value: " . $i->value . "\n"; print "----------\n"; } print "\n===========================\n"; } 
![https://i.imgur.com/qZPV4KH.png](https://i.imgur.com/qZPV4KH.png)
o submit_form é um dos metodos para preencher o formulario e depois enviar ele, para a gente usar esse metodo fazemos o request na pagina que tem esse formulario e depois usamos o metodo passando os parametros, sendo o form_number seguido da ordem daquele formulario e fields com os campos do formulario (no caso os inputs)
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://youtube.com"); $kodo->submit_form( form_number => 2, fields => { search_query => "kodo no kami" } ); print $kodo->uri . "\n"; 
o exemplo anterior tambem seria possivel via get direto pela propria url
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://www.youtube.com/results?search_query=kodo+no+kami"); 
tambem podemos usar o submit_form para enviar via POST ou usar o proprio metodo post (o metodo post é bem interessante a gente aprender a fazer ja que boa parte dos logins são feitos por ele)
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; #autentica no meu roteador $kodo->post("http://192.168.1.254/login.cgi",[username=>"admin",password=>"minhawaifu","submit.htm?login.htm"=>"send"]); #pula para pagina principal depois de logado $kodo->get("index.htm") print $kodo->content; 
podemos salvar a pagina normalmente abrindo um arquivo e escrevendo a requisição nele (podemos salvar qualquer tipo de arquivo não apenas as pagias html)
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://eofclub.in/download/EOFbookAsm.pdf"); open(KARQ,">asm.pdf"); print KARQ $kodo->content; close(KARQ); 
uma forma mais simples de salvar é usando o metodo save_content
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->get("https://eofclub.in/download/EOFbookAsm.pdf"); $kodo->save_content("asm.pdf"); 
usando o metodo agent podemos especificar um User-Agent
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->agent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36"); $kodo->get("https://google.com.br"); 
é possivel utilizar proxy bastando atribuir ele ao metodo proxy
#!/usbin/perl use WWW::Mechanize; my $kodo = new WWW::Mechanize; $kodo->proxy(["http","https"],"http://108.61.186.207:8080"); $kodo->get("http://ip-api.com/json/"); print $kodo->content . "\n";

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Events

Attended:
For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning)
The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)

Media

Decred Assembly episode 21 is available. @jy-p and lead dcrwallet developer @jrick discussed SPV from Satoshi's whitepaper, how it can be improved upon and what's coming in Decred.
Decred Assembly episodes 1-21 are available in audio only format here.
New instructional articles on stakey.club: Decrediton setup, Deleting the wallet, Installing Go, Installing dcrd, dcrd as a Linux service. Available in both English and Portuguese.
Decred scored #32 in the August issue of Chinese CCID ratings. The evaluation model was explained in this interview.

Community Discussions

Community stats:
Comm systems news:
After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:
Highlights:
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.
Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.
An unusual event was the chat about double negatives and other oddities in languages in #trading.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

All The Longreads (So Far)

I'm trying to work on a system that would pull only the longreads links out and shove them into their own RSS feed. It's super hacky and embarrassing and all the other things that prevent people from sharing code (I will eventually, I promise...it's only 11 lines of python right now). But, I should at least share all the links, by date, in a post. Please enjoy all the longreads:

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

#support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Relevant External

ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015.
A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use.
A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains.
New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred)
On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange.
Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

[Spoilers S2E11][Theory] The Annexation of the Democratic Republic of the Congo

Earlier this season we saw former Evil Corp CTO Terry Colby speaking with Evil Corp CEO Phillip Price. Price asks Colby to
pull some strings with an ambassador friend around a UN vote to help pave the way for China to annex the Congo. It may be just an(other) example of Phillip’s unassailable God complex or it could be a clue as to what Phillip and Whiterose have been scheming. Or both (S2E10 episode recap).
So, why the Democratic Republic of the Congo (DRC)? What do we know about the DRC that is true beyond the scope of Mr. Robot the television series?
The Mining industry of the Democratic Republic of the Congo is a significant factor in the world's production of cobalt, copper, diamond, tantalum, and tin, and gold as well. It is the Democratic Republic of the Congo's largest source of export income. In 2009, the Democratic Republic of the Congo (DRC) had an estimated $24 trillion in untapped mineral deposits, including the world's largest reserves of coltan and significant quantities of the world's cobalt (Wikipedia).
Earlier this year, Bloomberg reported that:
Chinese companies that buy cobalt from the Democratic Republic of Congo and supply mobile-phone and laptop makers such as Apple Inc. and Samsung Electronics Co. aren’t fully checking their suppliers and may be acquiring the mineral from mines that rely on child labor, Amnesty International said.
Let's disregard the whole child labor aspect here as it is not relevant to the story. The takeaway is that China already has deep roots in the DRC, as does the tech industry, of which we can assume Evil Corp can be included. In fact, the relationship between China and the DRC dates back to 1971.
In May of this year, the Financial Times reported that a Chinese corporation made the largest private investment in the DRC's history,
designed to secure China’s supplies of cobalt.
Furthermore,
“The majority of the cobalt is heading straight to China,” said Edward Spencer, an analyst at metals consultancy CRU. “Their global hold is huge.”
If the Tenke mine deal goes through, Chinese companies will be responsible for around 62 percent of global refined cobalt production next year, according to CRU estimates. Demand for the material is expected to soar by more than two-thirds over the next decade.
To put things in perspective, Mr. Robot the television series is currently in 2015, still dealing with the aftermath of the events of 5/9. This Chinese deal in the DRC may be indicative of things to come in the future of the Mr. Robot universe. For the time being, it is reasonable to assume that the Dark Army, White Rose & the Chinese Government must still leverage their relationship with Price & Evil Corps to gain access to Cobalt and/or other rare earth elements/minerals, as well as their R&D department.
And now for the Tinfoil
What gives? We should consider two possibilities here, but likely some combination of the two:
Remember, White Rose has been working for 20 years on a mysterious project housed in an Evil Corp's facility in Washington Township, NJ. Back in the real world, research and/or interest in the field of Quantum Computing dates back further than just 20 years. More importantly, there has been considerable progress made in recent years, even as recently as last month at the University of Maryland.
The University of Kentucky reported on just such a breakthrough back in 2012:
An important step toward fabrication of spintronics ("the Holy Grail," Menon says) is finding a semiconductor that has a net "spin" at room temperature. The biggest challenge is in finding a suitable material and figuring out how to set the spin. The UK-USF team showed that a flat sheet of pure carbon only one atom thick, called graphene, can be suitably engineered and used for this purpose when combined with atoms of the metallic element cobalt.
Using state-of-the-art theoretical computations, the UK-USF team demonstrated that by placing cobalt atoms in graphene "holes," created by removing one or two nearby carbon atoms, it is possible to set the spin states of the carbon atoms in a controlled way, which the researchers say is key to practical spintronics application for graphene.
This was followed up by a scholarly article in 2014, again noting the usefulness of Cobalt in Quantum Computing.
It is quite possible that Evil Corp, along with White Rose & the Dark Army made use of Cobalt in their project. Additionally, some kind of incident involving Cobalt could in turn be cause for the sudden illness that struck Elliot's father, Angela's mother, and others in Washington Township.
The metal [Cobalt] has the unfortunate property of producing a fine dust, causing problems with radiation protection. Cobalt from radiotherapy machines has been a serious hazard when not discarded properly, and one of the worst radiation contamination accidents in North America occurred in 1984, when a discarded radiotherapy unit containing cobalt-60 was mistakenly disassembled in a junkyard in Juarez, Mexico.
If Evil Corps were skirting the law, importing radioactive materials into the US behind the back of the U.S. Nuclear Regulatory Commission, they'd be in serious trouble. If the Feds believed they were building nuclear weapons, their import could be considered an act of treason.
Recall that Angela traveled down to D.C. to visit this very regulatory body after having stolen Evil Corp's Washington Township documents. The supposed "gas leak" could very well be a lie.
Other Considerations
u/laninata got me thinking after their posting about an arstechnica article from October 2015.
Serious weaknesses in the Internet's time-synchronization mechanism can be exploited to cause debilitating outages, snoop on encrypted communications, or tamper with Bitcoin transactions, computer scientists warned Wednesday.
The attacks could be used by malicious actors to wreak havoc on the Internet. An attack that prevented sensitive computers and servers from receiving regular time-synchronization updates could cause malfunctions on a mass scale.
Perhaps the digital signal on Angela's lawyer's television was disrupted by nefarious acts on US soil by the Dark Army.
Even worse, the attacks can be used to snoop on encrypted traffic or to bypass important security measures
attacks could be used to trick Bitcoin users into rejecting legitimate entries in the official blockchain for the digital currency, or to tamper with user authentication systems used by websites
So if a breakthrough in Quantum Computing is at play, Price may believe that he'll be able to cheat the new cryptocurrency system, while White Rose has more devious plans. Perhaps White Rose, the Dark Army & The Chinese Government plan to circumvent the security systems of US Defenses worldwide.
What does MrRobot have to say on the matter?
Closing Remarks
Out of all the tinfoil I have seen on MrRobot lately (more of my thoughts on that here), I feel that Quantum Computing presents the least tinfoil of all the tinfoil, with the exception of Cryptocurrency mining, for what could currently be at play in Washington Township.
It seems Evil Corps is on the verge of collapse, for good this time. If Evil Corps goes under, White Rose, the Dark Army, & the Chinese Government will necessarily need to uproot their operation in Washington Township. Perhaps Stage 2 hinges on Evil Corp's R&D department completing their research on a Quantum Computer, of which the Dark Army immediately plans to steal.
It would seem that in this scenario, with the health of the Global Economy at stake, China's desire to annex the Democratic Republic of the Congo will be the least of the USA's concern. Plus, China will then be able to reap the benefits of a potential $24 Trillion haul. In the short term, a $2 Trillion loss will not matter much.
Thoughts?
The Annexation of the Democratic Republic of the Congo (pt II)
