1041  Economy / Economics / China moves further towards cashless society on: October 02, 2018, 04:31:34 AM
South China Morning Post

An argument between staff at a cashless supermarket in northern China and an elderly man who did not know how to use his smartphone to buy a bunch of grapes has revived calls for help for those left behind in the digital economy.

The 67-year-old man, identified only by his surname Xie, tried to use cash to buy the fruit at a supermarket in Jixi, Heilongjiang province, on Sunday, video news site Pear Video reported.

Checkout workers rejected the money and insisted that he use his phone to pay via either WeChat Pay or Alipay, prompting the argument, according to the video.

Alipay is owned by Alibaba, which owns the South China Morning Post.

“I’ll leave if you don’t take the cash,” Xie said in the clip.

“Well, leave if you can,” the cashier replied.

As China goes increasingly cashless, PBOC says cash payment is still alive
Xie took the grapes and approached the door but was stopped by security guards.

“I know it’s not right to leave without paying,” Xie said. “But I have real yuan in my hands. It’s not fake money. Why are you humiliating this old man for not knowing how to use WeChat?”

A security guard later helped Xie process the payment with cash, the report said.
1042  Bitcoin / Press / [2018-10-02]From Farm to Blockchain: Walmart Tracks Its Lettuce on: October 02, 2018, 04:02:05 AM
New York Times
The giant retailer will begin requiring lettuce and spinach suppliers to contribute to a blockchain database that can rapidly pinpoint contamination.

When dozens of people across the country got sick from eating contaminated romaine lettuce this spring, Walmart did what many grocers would do: It cleared every shred off its shelves, just to be safe.

Walmart says it now has a better system for pinpointing which batches of leafy green vegetables might be contaminated. After a two-year pilot project, the retailer announced on Monday that it would be using a blockchain, the type of database technology behind Bitcoin, to keep track of every bag of spinach and head of lettuce.

By this time next year, more than 100 farms that supply Walmart with leafy green vegetables will be required to input detailed information about their food into a blockchain database developed by I.B.M. for Walmart and several other retailers exploring similar moves.

The burgeoning blockchain industry has generated a great deal of buzz, investment and experimentation. Central banks are exploring whether it would be good for tracking money flows. Eastman Kodak has explored a blockchain platform that could help photographers manage their collections and record ownership of their work, while a group of reporters and investors are using the technology to start a series of news publications.

But essentially the only real-world uses have come from cryptocurrencies like Bitcoin, which use their own blockchains to store transactions. Walmart is now trying to bring blockchain into the lexicon of everyday consumers.

“It is the first real instance of doing this at scale,” said Brigid McDermott, vice president of I.B.M. Blockchain.

I notice many ranked account from member's to legendary involved with ANN bumping with simple comment "great project". Usually I visit ANN thread to find spammer and bot. Once I see any ranked account spamming than obviously I visit his post history. I surprised they are bumping ANN Thread randomly. Of course I report all of spam post.

Just want to know how many good report need to permaban for ranked account? There is different good report need for each rank ? Like newbie need 1 good report for temp ban and 3 good report for permaban (AFAIK). It will helpful for me if I got correct answer. So I can report other spammer instead of reporting whole post history of ranked account.


The only difference is that newbies can have their posts deleted by Patrol. But those who have ranking up can not and need a direct action of the moderator.

Obviously, with only two moderators in this section, it would be difficult to have greater control. And there is no automatic way to ban users, who are repeat offenders.

I believe that the best way to reduce this is not more moderation. But with changes that make this action useless.

Why does it take a few days instead of a few hours? And for something like that to work, XRP needs to be in many more countries and exchanges than the current ones. I do not understand the process very well, it seems like a good idea, but it still needs a few years to become a killer feature.
1045  Bitcoin / Development & Technical Discussion / "Purpose: ProveFunds" bip-0322 on: October 02, 2018, 12:41:07 AM
There has been a BIP (https://github.com/bitcoin/bips/blob/master/bip-0322.mediawiki) made regarding a generic message signing format. Such a format would be able to be used for segwit, non-segwit, and any future changes. It is still being actively discussed however, so it probably won't go into Core or any other wallet software anytime soon.

Quote
Purpose: ProveFunds
The "ProveFunds" purpose generates a sighash and a scriptPubKey from a transaction, an output index, and a message. For multiple simultaneous proofs, it also requires access to the ordered list of proofs. It emits a VALID verification result code unless otherwise stated.

Let txid be the transaction ID of the transaction, and vout be the output index corresponding to the index of the output being spent
Return INVALID if the txid:vout pair already exists in `inputs` set, otherwise insert it
Return SPENT if the txid/vout is not a valid UTXO according to a Bitcoin node[3]
Extract scriptPubKey from transaction output
Define the message pre-image as the concatenation of the following components:[4]
the string "POF:"
the message, encoded in UTF-8 using Normalization Form Compatibility Decomposition (NFKD), including the null terminating character (i.e. write strlen(message) + 1 bytes, for a C string)
all transactions being proven for, as binary txid (little endian uint256) followed by index (little endian uint32), each separated by a single `0x00` byte
Let sighash = sha256(sha256(scriptPubKey || pre-image)

Would this function be for exchanges and large funds? I found it rather confusing. Could it serve to prove the funds that my account in the exchange says to have?

Would it be useful in a possible negotiation where I could prove that gathered several wallets, I would have funds to buy certain asset without the need to show all my public addresses?

I liked this news, although I am still a long way from being able to buy any model of watch with the BTC that I own. An interesting fact is that luxury watches are also considered as Store of Value. Fluffy, one of the developers of Monero, was in an event, concensus, with a watch valued at more than $ 800,000. And one of his arguments was exactly this one that was a way to secure his financial patrimony.

No way, pode ser uma boa meritar ele, mas e se ele não faz isso pra todo mundo que meritar ele?

Deve ter recebido o merit por ter postado algo bom, não por ter dado um merit antes..

Ah, sim. Não disse que foi relacionado, erro meu se passou essa impressão. Como falei, dei 1 merit como agradecimento e depois recebi 5 merits por algo totalmente diferente. Mas no fim acabei saindo no "lucro". E também estava tentando distribuir 2 pra criar um efeito cascata aqui na aba.

Glad to know that. I hope that more users will be attracted to post good content in the local sections after this decision. If I am not mistaken, some sources of merit were given instructions to try to distribute them in specific sections. I hope these sources follow these recommendations.
1052  Bitcoin / Press / [2019-09-28] Coinbase funded startup, launches protocol for shorting crypto on: September 28, 2018, 07:13:59 PM
Compound, the Coinbase and Andreessen Horowitz funded startup, launches its money market protocol for shorting cryptocurrencies or lending them to earn interest

Think Ethereum and other crypto coins are overvalued? Now you can make money when their prices fall via Compound, which is launching its money market protocol for shorting cryptocurrencies today. The Coinbase and Andreessen Horowitz-funded startup today opens its simple web interface allowing users to borrow and short Ethereum, 0x’s ZRX, Brave’s BAT, and Augur’s REP token, or lend them through Compound to earn interest.

Compound’s protocol isn’t just useful for crypto haters, or HODLers who want to generate interest instead of just having their coins gathering dust in a wallet.  “If/when Compound scales, this will lead to some really interesting improvements in market structure, namely, fairer prices” Compound CEO Robert Leshner tells me.



The startup spent the summer completing a security audit by Trail Of Bits and adding 26 hedge fund partners who will trade with Compound, offering liquidity to independent investors looking to be matched with borrowers or lenders. Next, the startup wants to offer a stablecoin on its protocol, bring in big financial institutions to add even more liquidity, and partner with a wallet provider to make signup faster.

Desculpe perguntar, mas o que rolou mês passado? Eu não costumo calcular o que recebo. Eu recebo e deixo na wallet, não tenho futucado muito.
A cotação máxima do dia na FOX foi de 25700 e o valor base para pagamento foi 28500.  Angry
Distorção de 10% na cotação que acho justo pagar no próximo pagamento, como o alegotardo comentou quando ele iria receber a mais comunicou o erro imediatamente...

Obrigado pelo alerta alegotardo, vou averiguar as diferenças e ver como ajustaremos no próximo mês.
Opa, só passando pra lembrar.  Wink
Aguardamos o ajuste junto com este pagamento;

E quem saiu da campanha como eu? Sad
Poderia receber também? Cheesy

Full Member recebeu 0.007362903 teria que ter recebido 0.008171206 diferença de 0.000811 ? 22 Reais de diferença no valor de hoje.

Dar mérits para o theymos e para gerente de Campanha. Duas coisas ridiculamente abomináveis
Pois é, também me dá náuseas... Seria aceitável se as campanhas além do pagamento normal, bonificassem com merits em adição ao pagamento, visto que em grande maioria das vezes o manager nem tem precisa dos merits...
 Obs: Seria contra as regras?

Na verdade eles criaram esse sistema de merits justamente para combater (o spam d)as campanhas.. Nossa aba local é bem boa, basta dar uma olhada na aba gringa de altcoins para ver o caos..

Eu sempre dava merits pros managers que faziam um bom trabalho nas campanhas que participava, também já dei para tradutores, galera que faz concurso de criação de logotipo, etc.. Tudo isso torna o fórum mais atrativo.. agora pro @theymos é demais Cheesy

Putz, eu dei merit pro Theymos. Cheesy
Mas o cara levou tempo pra por duas ou 3 vezes me explicar de maneira personalizada uma duvida minha. Mesma coisa com o achow101 e com o gmaxwell, que me respondeu por PM, em situações distintas. Dei tb pro SmokeTooMuch, que nem usa o forum mais, por uma situação antiga, como um agradecimento.

Acho que as vezes não é um absurdo usar Merit como se fosse o Gold do Reddit.

De qualquer maneira, venho tentando meritar sempre na aba local. Tento dar 2 quando é um full ou member. Eu tenho alguns de saldo e vou tentar distribuir por aqui.

Only a few local sections don't have sources now.


Quem é?Huh Pode se acusar ai seu fonte de Merito brasileiro!!! E comece a distribuir os meritos Grin Grin
1056  Alternate cryptocurrencies / Speculation (Altcoins) / Re: EOS executives left Block.one, the company that developed the platform on: September 28, 2018, 03:42:39 AM
And the price goes up more than compared to other projects. I tried short on EOS when I heard this news a few days ago on Bitmex and lost. It's unbelievable how much the price of it irrationally. And on with great volume of trading. In many exchanges, it is second by volume.

A project that stayed in ICO for a year. That was nothing but a token. That put a mainnet full of flaws in the air. That has already been shown to be conducted by a minority that has the power of veto and reversal. I believe that at some point the price will fall sharply or stabilize while the others rise. There are much more developed projects than this.

I liked this text. Very well structured, the main points that he pointed out are really the necessary ones. Now, there are more questions you should ask for something like that.

For me, without a doubt, the asset that I intend to keep for a long period is the BTC. But because I see in it an excellent store of value. It is safe, well tested, has a great team of developers and global acceptance. But that does not mean I only believe in him. I see a lot of potentials and need in projects that offer something that the BTC cannot offer as complete smart contracts and total anonymity.
1058  Bitcoin / Press / [2018-09-27] Coinbase Bundle, market-weighted 5 cryptocurrencies for $25 on: September 28, 2018, 02:39:05 AM
Coinbase adds Coinbase Bundle, a new offering that lets users buy a market-weighted sampling of its 5 available cryptocurrencies, for as little as $25

Coinbase  is shaking things up quite a bit lately and its latest tools are geared toward cryptocurrency traders just getting their toes wet.

On Thursday, the company announced that it would add a feature called Coinbase Bundle. The new offering lets users purchase a market-weighted sampling of Coinbase’s five available cryptocurrencies: Bitcoin, Ethereum, Bitcoin Cash, Litecoin and Ethereum Classic. The idea is that a bundle of coins offers users a starter pack for cryptocurrency trading on the platform with stakes of their choosing. In reality, until Coinbase adds more coins, it’s not exactly a diversified portfolio so much as a slightly counterbalanced selection of Coinbase’s current limited offerings.

In June, Coinbase introduced index funds targeted toward institutional investors in the U.S. While those funds required an investment between $250,000 and $20 million, Coinbase Bundle is geared toward the casual individual investor with bundles that start at $25. For beginning traders that prefer to follow rather than beat the market, betting on broad growth over time, a product like Coinbase Bundle makes sense. Or rather it will when Coinbase adds a lot more coins.

Users who buy a Coinbase Bundle can expect to see the funds appear in their wallet like normal. There, the funds will behave like separate assets that can be sold and sent elsewhere.

Beyond bundles, Coinbase is also launching a few educational cryptocurrency tools geared toward anyone still learning the ropes. The first of those tools is Coinbase Asset Pages, the company’s own CoinMarketCap-like database where anyone can view details about the top 50 coins by market cap, whether they’re listed by Coinbase or not.


Like other resources, Coinbase’s new tool will provide “historic trading data, current market cap, a description of the cryptocurrency, and links to relevant white papers and project websites.” Unlike other resources, Coinbase artificially lists its own offerings at the top rather than depicting those coins where they actually fall in terms of market cap.

Coinbase is also launching a dedicated learning hub on its site where new users can browse topics like “What is blockchain?” and “Where do cryptocurrencies get their value?” — in many cases, a good question. Given Coinbase’s appeal to brand-new users, it’s kind of surprising that this didn’t already exist. Particularly that it wasn’t implemented late last year when many wide-eyed investors bought it at all-time highs and were handed big losses in the months to come.

After mainstream interest in digital currencies cooled from the fever-dream highs of late 2017, making Coinbase’s famously user-friendly entry point into the cryptocurrency world even more approachable for first-time buyers, if many remain, can’t hurt. The company is also clearly readying for its plan to list coins well beyond its current limited offerings, a transformation that will see the platform evolve from its historical identity as a blue chip stock shop to something more akin to digital currency’s attractive, well-lit corner store.

Coinbase’s new top 50 asset pages and learning hub are live now. Coinbase Bundles, limited to the U.S. and Europe, will start showing up for users today, and the rollout will continue through the next few weeks.

Just a crappy Coinidol article that says nothing. Don't bothering wasting your time on it like I did.

These types of articles serve to fill up space. But they also attract lots of clicks and are easy to share. The point is that they generally confirm the feeling of several people. It is good to read an article stating that you are right to believe that the price will go up, even if the article does not bring any great news.

It is always important that these exchanges also operate with a Fiat-Crypto pair. I believe that this way provides more transparency and security to customers. It would be better if they started operating in more countries accepting other fiat pairs. Especially Dolar and Euro.

OP, thanks for post the picture too Smiley
