  Build a Blockchain and a Cryptocurrency from Scratch
Posted by: Carsten - 2018-10-04, 03:04 PM - Forum: General discussion - Replies (13)

On Udemy you can find a course called "Build a Blockchain and a Cryptocurrency from Scratch"  https://www.udemy.com/build-blockchain/.

I'm halfway through the course that is excellent in explaining the inner workings of blockchain. You will build a blockchain slowly and in time the instructor add more and more complexity when needed. Even I'm not yet done with the course I will recommend this to everyone. 

The code is written in Java script by use of a tool called Node.js and the editor used is the exceptional good free Microsoft Visual Studio Code (not the same as Visual Studio). He also brings in a free tool called Postman. It will of course be an advantage if you know a bit about programming. Some part could be a bit hard if you never have done any programming. That said from the comments I can see some nonprogrammers are trying.

  Q4 2018: Bull run or not?
Posted by: Hugues - 2018-10-03, 07:43 AM - Forum: Bitcoin and Altcoin - Replies (24)

The last few weeks we have seen little movements upwards for many cryptos.
I have a strong feeling that we are at the eve of a massive bull run.
It is not to predict, but I have the feeling BTC will shoot in the direction of $50000 somewhere end 2018-beginning 2019.
The other important cryptos will follow this trend.
But I also believe this could be the end for lots of shit coins.

A Coinbase-backed platform called Compound is now officially online, giving users the ability to lend their coins in exchange for interest or collateral.
Users and applications can seamlessly earn interest or borrow ERC-20 tokens without managing an order book; Compound automatically optimizes interest rates based on the supply and demand unique to each asset.

  Electroneum #ETN has exploded in value
Posted by: Carsten - 2018-09-23, 10:19 AM - Forum: Bitcoin and Altcoin - Replies (22)

I have seen a rise in the price of Electroneum over the last couple of days. It seems to be an honest team and maybe a good long term investment. What do you guys thin?

  Atomic Swaps: The Solution for DEX
Posted by: Hugues - 2018-09-19, 06:30 PM - Forum: Bitcoin and Altcoin - Replies (8)

As promissed in another post today.
Hope it can help you to see why decentralised exchanges are the futur.

Atomic swaps, or cross-blockchain trading, is the exchange of one cryptocurrency to another cryptocurrency, without the need to call in a third party. Simply put: I exchange my Bitcoin against your Ethereum.

A relatively new piece of technology. Atomic cross-chain trading is looking for a revolution in the way users interact. For example, if Hugues owns 5 Bitcoins, but instead wants 100 Litecoins, he would have to trade via an exchange, so via a third party. However, with Atomic Swaps, if Bob owns 100 Litecoins and wants 5 Bitcoins instead, then Bob and Hugues could trade. For example, to prevent Hugues from accepting Bob's 100 Litecoins, but then not sending his 5 Bitcoins, Atomic swaps uses so-called hash timelocked contracts (HTLCs).

Hash timelocked contracts ensure that the Atomic swap process is completely reliable by ensuring that both meet the obligations of the exchange. HTLCs require the recipient of a payment to confirm receipt of the payment before expiry of the payment term by generating a cryptographic proof of payment. Or the recipient risks the risk of losing the right to the claim, thus returning the payment to the sender.

In order to establish a trade transaction between Hugues and Bob, both parties must therefore present their transaction to their respective blockchain, Hugues to the Bitcoin blockchain and Bob to the Litecoin blockchain. In order to claim Bob's 100 Litecoins, Hugues has to produce a number that he knows only to provide a cryptographic key and thus a proof of payment. And Bob, in order to claim the 5 Bitcoins sent from Hugues, must also mention the same number that was used to generate the cryptographic key.
