Qualquer pessoa que tenha conhecimento com programação e entenda callbacks, vai entender o funcionamento superficial do Chainlink.

1. Chamo uma função do contrato da Chainlink na ETH ("quero os dados da API X").
2. Os nodes da Chainlink fazem a requisição, cuidam da segurança e integridade dos dados.
3. Os nodes da Chainlink enviam a solução ao contrado da Chainlink na ETH, chamando a função que recebe os dados.
4. Esse contrato chama uma função de callback do contrato inicial que chamou o Chainlink.
5. Essa função callback faz o que quiser com os dados da API, incluindo atualizar variaveis (e.g "bitcoinPriceAtCoinbase").

Ou seja, dá para pegar qualquer dado de qualquer API e fazer o que quiser com ela, inclusive alterar variaveis que cuidam dos modelos de négocio do contrato.

Impedimento: Taxas para todas essas tx. Chamada ao Chainlink, chamada callback do contrato e taxa de pagamento pela solução.

Anyone here thinks that Slovenia has a chance to win the gold medal?

A notícia não esclarece por completo o caso. O que deu para entender é que as exchanges eram apenas de fachada, ou seja, eram usadas por membros da quadrilha para dar origem a dinheiro ilícito. Não existiam clientes verdadeiros. Eram uma espécie de "lavanderia de dinheiro". 

Last season Lowry wanted out already isn't it? So that alone tells us that the Toronto Raptors are going to rebuild without Lowry. But it is interesting to hear that Siakam wanted out of Toronto since he just sign a huge deal with them and he is the next to be the face of Toronto when Lowry goes out.

Of course, the American team is still the main favorite of this Olympic tournament and this defeat will not change that.
However, this defeat once again showed that the American team is not untouchable, that they are vulnerable and that they can be defeated.
This means that in the continuation of the tournament, everyone will try to repeat this feat of France and will not enter the matches with America with the fear of a big defeat, but with the desire to try to win.
Obviously, the American players did not come fully prepared for this tournament and it will be difficult for them to win the gold medal again.
The difference between America and the rest of the world in basketball is getting smaller every year and this can be seen in the performances of the American national team in recent years.
I think Spain, France and Australia will be America’s main rivals in the fight for gold.

Yeah, we can take injuries into the account, but Bucks did their thing this season, they fought very hard every game and then we have seen Giannis evolved and matured as a elite basketball player, so we shouldn't take everything away from him.

So let's see if they can repeat next season, the good thing is that they are not the favourite, and they are an underdog so an outright bet could be good for us. And I think even if Lakers or Nets are healthy, they can still find arguments against the Bucks for winning the championship.  (Lebron was too old, Nets big 3 didn't click, etc).

Still confident the USA will make it to the semis. Well, loving the statement by Evan Fournier that they may be tough or something but with team effort from them they make to win against the former Olympic gold medalist. We're not seeing a high caliber USA team this time around looks like USA hasn't consider a good contender team.

Yes it's the first time they loses since 2004 in the olympic competition, to continue they need to win against the Czech Republic or Iran because only the 2 first teams of each group, and the 2 best third teams of all groups are selected for the quarter-finals.

Não conheço a fundo essas moedas. Mas a limitação de usar apenas dados internos ao blockchain é uma limitação da tecnologia , da forma q o blockchain é desenhado.
Então, a não ser que tenha um oráculo nativo nessas moedas, a necessidade de um middleware (oracle) permanece.

They can't repeat championship, that was a one time trophy due to too many injuries on opponents. Next year there won't be this much injuries.

O que torna isso inviável hoje é que não é possivel colocar em um smartcontract uma informação externa ao blockchain. Por isso que soluções como o chainlink (oráculos, que passam informações externas para o blockchain) bombaram uma época. Mas não sei como andam essas soluções hoje e por que ainda não estão funcionando (ou se já tem algo funcionando).

So you say; Raptors championship is a fraud too? Stop this discrediting. I thought you guys are NBA viewers for long.

If the Nets are healthy, the Bucks will adjust. If the Lakers are healthy, the Suns will adjust.

There's no 100% assurance that these eliminated teams if healthy will beat instead the Bucks and Suns. You are just creating speculations based on the big names on the teams since it's Lebron, AD, Durant, Irving, Harden. These are just normal players too they are beatable.

Edit:  unbeatable to beatable lol typo

Cada um com sua paranoia. No meu caso eu sou paranoico em relação a doenças. Sou hipocondríaco ao extremo. Não pode aparecer um assunto relacionado a doenças que eu já vou lá e leio. O engraçado disso é que por pouco eu não fui cursar medicina. Imagina só um médico hipocondríaco. Quanto a bens materiais ou "virtuais" não tenho tanta paranoia não. Vai entender.
