Atomic Swap. What It Is and Its Importance for the World of Cryptocurrencies

atomic swap

Is the ability to transfer coins that are based on different blockchains without third parties real? In general, yes, it is, but as elsewhere, there are pitfalls and nuances in this issue. Today we will talk about such a development as an atomic swap, we will learn how it works and what prospects it has.

1. What is an atomic swap?

Recently, the cryptocurrency community has been discussing a new and truly revolutionary idea that can transform the industry beyond recognition. Atomic swaps make it possible to conduct trading operations between different cryptocurrencies without using the help of third parties.

In order for the parties to not deceive each other, both transactions are synchronized. If one of the participants suddenly decides to refuse to conduct an exchange operation, the funds will return to their holders.

Test atomic swaps are already functioning; if they prove their reliability, then this will have colossal consequences for the entire cryptocurrency industry. This technology can arrange a total restructuring of orders in the market, up to the complete replacement of the familiar cryptocurrency exchanges. With the help of atomic swaps investors can get full access and control over their own assets.

2. How does it work?

To understand this rather difficult process it is necessary to simplify and have a visual picture in the head. So, let’s take two users A and B. User A is the initiator of this imaginary transaction. To begin with, he creates a place where funds will be stored at the time of the swap, we’ll call it the deposit box or the address of the contract. To open it you need several components:

  • secret phrase (generated by user A);
  • electronic signature of user B.

In order for user B not to be able to collect money ahead of time, user A should never transfer a secret phrase-number to him, but hash it in advance. Hash is the encryption of any data; blockchain, in principle, works on its basis.

After that, the user B has the opportunity to view the cell and make sure that there is the required number of coins; then B creates its contract address based on the hash of the A user’s cell. Both of these cells can be opened using the same key. Then there is the final stage of the transaction, when A signs cell of B and redeems the funds bound to the wallet. Secret phrase-number is transferred to B and that one can open the cell in which reserved funds of user A are kept. This completes the transaction.

3. Prospects for the future

As we already mentioned above, based on the technology of atomic swaps, it is possible to create absolutely decentralized exchanges, which will be impossible to crack or compromise. If Charlie Lee and the team are able to solve a number of problems and bottlenecks in this technology, then this will be a real revolution in the cryptocurrency industry. At this point in time, the technology works only with such coins:

  • Litecoin;
  • Decred;
  • Bitcoin;
  • Viacoin;
  • Vertcoin.

It should be noted that the source code of this technology is in the public domain, for this reason, any developer, if desires, can introduce it into his offspring.

4. Conclusion

Atomic swap is a truly revolutionary idea, which excites the minds of many participants in the cryptocurrency market. A successful scenario of this direction will change the industry forever: new services will appear, coins will become more flexible type of assets, and users will have full control over their own funds.

The Stablecoins: What Is It and Why Is It So Popular Now?

Cryptocurrencies and increased volatility are almost synonymous. The digital coins market can easily fall or grow up in price by 10% -15% in a day. But along with unstable coins in the industry there are also so-called stablecoins, which will be discussed in this article.

5. Conclusion

1. What is the stablecoins?

The main idea of ​​cryptocurrencies is creation of the absolutely decentralized payment instrument, which will not have any relations with usual valuable assets. But at this stage of cryptocurrencies development it is not possible to completely abandon fiat yet. In any case, currency of digital coins is counted in dollars, euros and other fiat currencies for convenience.

In order to popularize cryptocurrencies, it is necessary to create a bridge between traditional and digital financial sectors. Therefore, in 2015, for the first time, the best qualities of cryptocurrency and fiat money were combined, and so the stablecoins appeared.

The first stable cryptocurrency was Tether, it is still the most popular stable digital coin. Tether is backed up by the US dollar. This coin takes 8th place in the global Coinmarketcap rating , with total capitalization almost $2.5 billion.

But it is worth noting, that there are already enough of such stablecoins on the market. Each of them is reinforced by a certain physical asset:

  • other fiat currencies (the euro, the pound, the yen, etc.);
  • the gold and other precious metals;
  • the minerals;
  • the property;
  • etc.

It is only beginning, since it is already obvious that a digital coin can be pegged to absolutely any physical product. Thus, it is possible to maximally protect assets from cryptocurrency volatility, and at the same time to enjoy all the benefits of decentralization.

2. The list of the most famous stablecoins

So, as it was mentioned before, the very first stable USD Coin was Tether. Its rate is backed up 1:1 to the US dollar. This project was started in 2015. Literally a year later, its euro equivalent  EURT was represented to wide audience. After some time, the Japanese yen cryptocurrency appeared. As many analysts had suggested, these two coins were not widely spread.

At the beginning of  2016, DigixDAO coin was started, its rate was pegged to the gold: 1 token equals the cost of 1 gram of gold. It should be noted, that there were quite many projects, which tried to peg their coins to the gold (OneGram, GoldMint, HelloGold, AutumCoin, etc.). The silver was not forgotten either (EthereumLink, Silvercoin, Silver Back Coin, etc.). In Israel, the group of developers released stablecoin Carat, the currency of which, as the name implies, was pegged to the diamonds.

As you might have guessed, there is a huge amount of coins on the market, which are somehow backed up by physical assets, but let’s take a closer look at two more sensational dollar projects.

Gemini Dollar is the world’s first regulated stable digital coin, which is pegged to the US dollar. This project is still too young and it is not clear how it will show itself in future. Now the coin took a 1723th place in the global Coinmarketcap rating.

TrustToken is another project whose developers want to connect real and digital economy. They themselves estimate it in 256 trillion dollars. Within of this platform, the TrueUSD token was issued, it`s rate was pegged to the US dollar. Soon the developers promise to release tokens, which will be pegged to other popular fiat currencies. On the one hand, this project has many advantages (ability to implement blockchain into real sectors of economy, introduction of smart contracts, strong team), and on the other hand, there are many disadvantages (lack of roadmap, centralization, possible vulnerabilities of smart contracts, etc. ).

3. Advantages and disadvantages

First of all, let`s list the main advantages of stablecoins, there are quite a lot of them:

  • Holders of such coins can use all benefits of the digital economy, and at the same time be relatively calm about their capital`s safety. As a rule, cryptocurrency exchanges do not work with fiat currencies. And with stablecoins help it is possible to operate with dollar (or any other currency) right on an exchange. It substantially simplifies a digital coins trading process.
  • Thus people, who have no confidence in banks, can secure their capital without contact with traditional financial structures.
  • Stablecoins can be effectively used in trade and business, because their price does not change with time. A seller can safely accept $1,000 in coin equivalent, since its value will not fall down, even in conditions of market fluctuations.

Unfortunately, stablecoins are not without flaws, and now let’s take a closer look at them:

  • Such coins are absolutely useless as an investment asset. After all, 1,000 coins purchased for 1,000 dollars today, will cost the same 1,000 dollars in a few years (and it is, at best, if the project does not close).
  • Pegging to the value of a particular physical product does not protect against fluctuation of the asset itself.
  • There is a risk of freezing company’s reserve accounts, which will lead to impossibility of fulfilling debt obligations to tokens holders.
  • Stablecoins can be stolen at once in two ways (digital and physical).
  • Storing of a physical asset entails additional expenses, which often fall on its owner’s shoulders.

4. Future prospects

Because of several factors, today stablecoins are only a good concept, which is still far from widespread use. To a large extent, this direction has good prospects in future. Financial transactions which will be made through stable cryptocurrencies, will be able to bring the real economy to a qualitatively new level. With their help, bureaucratic procedures can be avoided, and due to smart contract technology, it will be possible to do without intermediaries.

5. Conclusion

The stablecoins are digital coins, whose currency is not exposed to increased volatility, because it is pegged to the value of a certain physical asset. With such coins it is possible to connect real and digital economy. But at this point, stablecoins have a number of problems which need to be solved, only after that it will be possible to talk about their widespread use.

Bitcoin Cash: Overview, Advantages and Disadvantages, Details of The Hard Forks

In this article we will talk about the most famous bitcoin`s hard fork – the Bitcoin Cash: it`s advantages and disadvantages, forecast for the future, as well as the hard fork, which will happen on November 15, 2018.

  2. Disadvantages of Bitcoin Cash
  3. Briefly about the hard fork Bitcoin Cash
  4. Conclusion

1. Briefly about Bitcoin Cash and comparison with Bitcoin

The main popularizer of the “new” coin is Roger Ver. He is quite famous person in crypto world. He was one of the first cryptocurrency investors. Due to increased attention to this industry, he became known as Bitcoin Jesus. But later, Ver decided to actively promote the hard fork (a branch) of the first cryptocurrency – the Bitcoin Cash. The network split occurred on August 1, 2017.

What is the difference between the BTC and the BCH?

  • Increasing of transaction`s speed in several times. The main feature of the new coin is an increased block`s size to 8 MB. On May 15, 2018, developers released the update, after which the block`s size increased to 32 MB. This solution made it possible to record much more transactions in one block, and thereby to increase network bandwidth.
  • Low commissions. Bitcoin Cash has very small commissions $0,05 – $0,010, which is significantly lower than that of the “older brother” $8 – $15.
  • With the current network load, a queue of unconfirmed transactions does not exceed 200 – 250, whereas with the original Bitcoin, this number can reach 7,000 – 10,000.

2. Disadvantages of Bitcoin Cash

Significant disadvantage of this fork is the automatic adjustment of the network`s computing complexity. Unfortunately, it has direct dependence on the speed of extraction of new data. That is, if for a certain amount of time miners get an insufficient number of blocks, then complexity decreases. This pattern works in both directions.

Miners started to use this vulnerability and got BCH in periods of complexity recession, and when the situation changed, they turned to BTC. Such actions led to the network`s destabilization and increased volatility of the BCH rate. This problem has not been solved till this day, but the development team manages to restrain it.

Cryptocurrency investors do not consider Bitcoin Cash as a long-term asset yet. This coin is more used as a speculative tool. For this reason, at the moment BCH has rather vague and uncertain future.

3. Briefly about the hard fork Bitcoin Cash

The hard fork of Bitcoin Cash was on November 15, 2018. After this event, the network received two incompatible consensus protocols BCHABC и BCHSV. The community of coin divided into two parts: on the one hand Roger Ver, and on the other Craig Wright. The outbreak of the conflict is considered to be Bitcoin ABC update, which began to support smart contracts and atomic swaps. In response to this update, Craig Wright offered the community his vision for the future development of the project. He proposed to increase the block`s size up to 128 MB. Such decision was not supported by Roger Ver and his part of miners. Because of this, another coin will now appear in the cryptocurrency world.

This is very good news for BCH holders. The matter is that after hard fork, investors received the same amount of coins of the new network, which complies with their BCH`s balance.

Against this background, the Bitcoin Cash rate grew up by almost 50% only for the first week of November.

This growth was artificial, therefore, we observed the same rapid rollback before the hard fork.

4. Conclusion

Bitcoin Cash is a project with rather big ambitions, ultimate goal of which is to push the original Bitcoin from the first place. In fact, BCH has fewer problems with scaling, and also can boast of low transaction commissions. But on the other hand, there is conflict between developers, still unsolved problem of automatic control of complexity, as well as increased volatility. Now it is hard to make long-term forecasts for Bitcoin Cash, as it is not clear yet, which of two networks will be more stable.

Three Hellish Days for Cryptocurrency: Reasons of The Fall of The Currency and What To Do Next?

The current condition of the cryptocurrency market raises a number of question from traders. For the third day, the industry is either trying to revive Bitcoin and other cryptocurrencies, or just watching the collapse of the course.

The question of what caused the collapse of the market and what should do those who still have cryptocurrency  – makes world crazy. That is why, The Coin Shark have found answers for all of these questions and analysed per minute history of the fall of currency of Bitcoin.

The Chronology of the fall from 14th to 16th November

Wednesday, November,14 , Bitcoin break another 2018 bottom.  According to data of CoinMarketCap, at 11:34 UTC the rate of the first cryptocurrency behaved stably, being at $6 365.

Nothing foretold troubles, but at 17:19 UTC began unexpected fall, which last till the 19:19 UTC, where the price of BTC remained in half-dead condition at $5 765. Therefore, the capitalisation of the marked fell to $102 billion.

After that, Bitcoin started to resist. In 20:04 UTC the currency show vital signs, increased to $5 858. But still, the end of 14th November was not a happy ending. In 22:48 UTC was settled a new record – $5 568.

If compare the data with an individual market, then on a Bitstamp the price of the BTC has already dropped to $5 534, and on the Kraken – $5 510. Last two weeks, Bitfinex exchange trade Bitcoin more than $6 000 per each unit.

It turned out, that the 14th of November was still far from the end of BTC fall. According to CoinMarketCap, Thursday, November, 15, at 17:04 UTC, Bitcoin shocked everybody with the course of $5 358. On Bitstamp the first cryptocurrency down to $5 446, and on the Bitfinex – $5 638. At this point, this is the lowest course from the end of October, 2017.

The condition of the cryptocurrency market for the last year is unstable. It is accompanied by unexpectable highs, as well as painful falls. But not only Bitcoin drop it’s price position on 14th of November. Together with it, into a deep red zone came the major part of other cryptocurrencies. In doing so, the total capitalisation fell by $190 billion.

At the writing of this article, 16th of November, the condition of the cryptocurrency market is still in critical position – the course of Bitcoin stood at $5 500, and Ethereum backed down the second place in capitalisation Ripple.

What caused the collapse?

Just think about it, less than 24 hours ago, it was possible to sell the BTC on a thousand dollar higher. Probably, it is impossible to define why “the foundation was cracked” under the cryptocurrency, as for the example it can be done in a regular market. In the digital, the effect is first  seen and only than the reason becomes known.

Reason #1: Contagious effect

On the basis of past, the cause of the fall have psychological nature.
For example, people are massively starting to buy cryptocurrencies or fanatically selling.

Reason #2 : Direct correlation

Each financial currency  pegged to its government, as for the example dollar – to the US economy. Cryptocurrency pegged with the people, which are both buying or selling it.

Reason #3: Global Bitcoin influence

Ironically, but there is a theory, that the general condition of the cryptocurrency is affected by Bitcoin. The value of all digital market is estimated in $182 billion, the $90 billion of which belongs to BTC. The majority of cryptocurrencies  should be transferred especially in Bitcoin, before the sale.
And now imagine, that selling of Bitcoin will start simultaneously several major players of the market. After this, the BTC prices are lowering, and this cause  the panic attacks more than ones: “ Buy everything and as quickly as possible, while the price is low!” – this makes the course to grow.

What should do the owners of cryptocurrency: sell or wait?

It depends on the inner aspects of each owner. Even when the course is rising – it still have cycles of fall.

Who and how will affect the collapse of rate?  

Cryptocurrency is the unstable tool. It’s system decentralised and doesn’t have the management center. Digital currency should strengthen the positions, so it can give the accurate forecast for the future. But, it appeared, that this fall will have no affect on ordinary users.

There is no denying, that in a consequence many crypto-business will close. Cryptocurrency exchange are in the minimum risk area, as in such cases the number of transaction increases.

Most of all, miners and the owners of the mining field will suffer the most. Since, the profitability depends on the price of extracted cryptocurrency. Within recent events, it is clear that mining is unprofitable occupation.
