What is Bitcoin? 356

One blame it of being a speculative bubble, while the others call it a digital revolution – everybody has its own opinion about world’s first cryptocurrency — Bitcoin. Some people believe that cryptocurrency era that began with Bitcoin back in 2009 will become one of the greatest events in the history of economy, the others believe that digital bubble is likely to blow up soon. Anyway, everyone talks about Bitcoin and some even manage to make millions on it. The Coin Shark will explain, what Bitcoin is in simple terms.

Researches came up with different ideas to create a decentralized cryptographic currency already in the end of the 20th century. In 2008 a mysterious person or a group of people called Satoshi  Nakamoto, that still remains unknown published the description of a peer-to-peer payment system. This means that each user of such a network has equal rights – there’s no center and periphery, server and client.  

Bitcoin is a decentralized digital currency. Decentralized means that all transactions are made directly between users without any agents, like banks, payment systems, and without government control. Digital means that Bitcoin exists as a recording of transaction data. The data is recorded in blocks and the system of all blocks is called blockchain. This technology is the basis of Bitcoin, other digital currencies and blockchain-platforms. Each block is the result of calculations — a certain algorithm necessary to record information in the block. These calculations are carried out by miners, who create new blocks and receive a reward for that. The whole blockchain is located on every user device, So there’s no way someone can hack this distributed database unless they can access hundreds of thousands of devices at the same time. Safety and reliability are indeed Bitcoin’s major advantages. However, there is also the flip side of the coin. It is not possible to cancel or change transactions after they are made, so you’d better check everything very carefully in order not to send your cryptocurrency to somebody by mistake.

Bitcoin’s issue is limited — miners can generate as much as 21 million BTC. By the way, the more blocks are there, the more computing power is necessary to produce new ones.

Today many people use Bitcoin not only as an investment tool, but also as a mean of payment. According to Forbes, first Bitcoin transaction was made by an american Laszlo Hanyecz. Back in 2010 he offered 10,000 ВТС for a delivery of two pizzas. Today, as one digital coin costs around $11.5 thousand, it is possible to purchase real estate, pay for a hotel room or to pay in shops with Bitcoin.

Bitcoin’s greatest potential are independent transactions. Perhaps it will become a foundation of new and really free economy, that does not depend on central banks and state regulatory authorities. This currency exists as long as there is the Internet. On the other hand, Bitcoin does not have any physical value that it is based on, so Bitcoin rate can be rather volatile  and depend on speculations. Anyway, today Bitcoin would be an appealing investment, that is definitely worth trying unless you sell all your property to buy BTC.

Where is it Better to Exchange Coins: On the Stock Exchange or In the Exchanger? 519

exchange coin

The vast majority of all operations with the cryptocurrency is carried out on exchanges with multi-million turnover. And what are the exchangers offering promising conditions for buying / selling the cryptocurrency? How do they differ from exchanges? We will consider it in this material.

  2. How does the online exchange of cryptocurrency work?
  3. Principal differences between the stock exchange and the exchanger
  4. Where is it better to buy/sell cryptocurrency
  5. Advantages of online exchangers
  6. What should a safe exchanger look like?
  7. Conclusion   

1. What is the exchanger?

The name gives the answer – it is the place where you can exchange the cryptocurrency for fiat or for other coins. There are two types of exchangers:

  • Online. This is a site where a visitor can make a purchase / sale of a cryptocurrency at a fixed rate.
  • Offline. Here, the currency can be exchanged for real money, having received a cache in the specified place – at the checkout or office.

Exactly the same is the work of known to all exchangers, working exclusively with fiat money.

2. How does the online exchange of cryptocurrency work?

The main condition for someone who wants to buy a coin is the presence of a cryptowallet. If any, the procedure is simple:

  1. Simple and not always compulsory registration;
  2. In the menu, find the currency you want to buy or sell;
  3. Fill in the fields with the requisites;
  4. Agree with the exchange rules and click “Exchange”.

You will be notified of the operation by e-mail notification. Cryptocurrency exchangers work in different modes:

  • Manual mode assumes that each operation is processed by an operator. It’s always long.
  • In semi-automatic mode, Bitcoin exchange can last half an hour or more, depending on the exchanger.
  • In the automatic mode, currency cranes operate with immediate withdrawal of funds.

The cryptocurrency exchanger has little to do with a stock exchange, with its adjustments, quotations, orders. But the investor is more interested in the price than the technical side of the exchange.

3. Principal differences between the stock exchange and the exchanger

At the exchange there are traders who determine the price of coins. In the exchanger, trading is inappropriate, because the course is determined by the owner of the resource. Is it good or bad?

On the one hand, there is no place for exchange speculation on the exchanger. On the other hand, there is always a real coin price on the stock exchange, which rarely coincides with the exchanger’s rate.

4. Where is it better to buy/sell cryptocurrency

If it is a matter of profit, then on the exchange with its market rate. The owner of the exchanger, of course, is guided by stock quotes, but his rate is always higher. By the way, the commission in the online cryptocurrency exchanger can differ from the stock exchange in the tens, and even hundreds of times.

In terms of convenience, the exchange also looks preferable, as it works around the clock without days off, which cannot be said about many exchangers.

An important point is the amount of currency reserves. If there are no problems for an exchange with a multimillion-dollar daily turnover  to make almost any transaction , then a poor exchanger can sometimes offer to wait an hour or two before the required amount of bitcoins or fiat appears. The security of the exchangers also raises doubts. If the top-level exchange is guaranteed to be protected against cyber attacks, then how this issue is decided by the owner of the exchanger is known only to him.

5. Advantages of online exchangers

All of the information mentioned above does not exclude the essential advantages of the cryptocurrency exchangers:

  • User-friendly interface. Registration procedure is extremely simplified, and often completely absent.
  • Any exchanger is fully integrated with all popular payment systems.
  • For registered customers, there is a program that provides an incremental discount for each subsequent exchange.

But all these advantages do not matter if the exchanger offers a disadvantageous course.

6. How should a safe exchanger look like?

A successful exchanger must work at least for a year. To be confident in successful exchange, you should take an interest in reviews on independent resources. In view of the volatility of the cryptocurrency, it is necessary to give preference to exchangers with automatic or semi-automatic mode. A good exchanger has enough reserves of cryptocurrency and fiat, it and its support work around the clock.

7. Conclusion

Online exchanger is a fast service for buying or selling coins. But it is completely unfit for trader strategies, since its commission can eat all the potential profits.

What Is the Process of Tokenization or How Can Any Person Create His/Her Own Token? 1437

tokenization

In this article, we will consider such a concept as tokenization. We will learn how it is used by various companies and how the technology of blockchain is used here.

  1. The concept of “tokenization”
  2. The process of tokenization in the modern sense
  3. Tokenization in tandem with blockchain technology
  4. Conclusion

1. The concept of “tokenization”

Initially, tokenization technology was used to implement secure online payments. With its help, you can encrypt the data of real details and replace them with the generated hash code – a token. This is how the first concept of tokenization looked like, and the modern designation, which is now widespread in blockchain projects, has gone from there. Today the word “token” refers to a unit of an asset in a certain company.

2. The process of tokenization in the modern sense

Tokens can be compared to the labels that fill the desktop of each computer. Shortcuts are created in order not to litter drive “C” with heavy files, but at the same time to have quick access to them. Shortcuts are just the way to the program, folder, etc. If you delete a file where the shortcut leads, then the latter will not represent itself any more.

So, by analogy with the creation of shortcuts on the computer, in our time, the business is tokenized in various spheres of activity. Tokens can be created for anything (electricity, oil, gold, cattle, wheat, real estate, part of any enterprise’s funds, intellectual property, etc.). Tokenization works with both physical and virtual objects. This practice greatly simplifies and accelerates the mobility of assets, because you need logistics, a certain amount of documentation to move a real object, and the converting of the token is slightly more than nothing.

Tokenization of homogeneous objects is a fairly simple task. For example, one token is equal to 1 gram of gold, but it can be further divided into smaller parts. It is necessary to increase the liquidity of the asset. Tokenization problems arise if the items that need to be transferred to the digital space have different values ​​(real estate, art objects, etc.). In this case, this process becomes a little more complicated, since it requires the contribution of additional variables. Platforms that offer to tokenize heterogeneous objects already exist (Artex, Atlant, etc.), but each of them is confined to its own narrow niche.

3. Tokenization in tandem with blockchain technology

Probably, it seems strange, but in fact, the technology of blockchain is not mandatory to produce a tokenization of the project. Actually, anyone can make an issue of tokens, backing them up with any of their tangible or intangible property. To do this, you only need to run the platform, where you can transfer the rights to own the asset in the token.

Then why do the overwhelming majority of projects use blockchain technology for the tokenization of their own assets? It’s all due to the transparency that this technology provides. With its help, it is guaranteed that there is no third-party intervention in the data registry. ICO tokenization in tandem with blockchain eliminates the issue of confidence in the developers. Also, the undeniable advantage of using this technology is the absence of intermediaries between buyers and sellers of assets, which simplifies and significantly speeds up the exchange process.

4. Conclusion

The process of tokenization involves the transfer of tangible or intangible assets into the digital space (tokens). This significantly increases the liquidity and mobility of the asset. With the help of blockchain technology the process can be completely transparent and safe, and also you can remove any intermediaries from the chain.

The Essence of the Blockchain Technology and Cryptocurrency 716

essence of blockchain and cryptocurrency

In the last couple of decades, technological progress has accelerated its full-scale expansion on pretty much all spheres of human life. Every year there appears something new that can change the world and make it a little easier and more efficient. One of such inventions is the technology of blockchain and the new payment system created on its basis – cryptocurrency. In this article, we will try to explain what the blockchain technology is and why cryptocurrencies will change the world in the next 5-10 years.

  1. The essence of the blockchain technology
  2. Cryptocurrency types and their difference from other payment systems
  3. How are coins extracted?
  4. Forecasts for the cryptocurrency market
  5. Conclusion

1. The essence of the blockchain technology

Blockchain is quite a young technology, the first application that was launched on its base was Bitcoin, thus, blockchain is often referred to as a purely transactional network. In fact, the practical application of this technology is unlimited. Now there are blockchain applications that work in the fields of logistics, medicine, law, trade, rent, etc.

In short, blockchain is a chain, which consists of a large number of blocks, where various information can be stored. Each subsequent block stores data about each previous one in an encrypted form. The uniqueness of the technology lies in the fact that the entire register of data is decentralized, and its copies are simultaneously stored on tens of thousands of computers around the world. This provides the highest level of protection from third-party interventions. The data stored in the system is almost impossible to compromise, replace or delete.

Let’s review an example of where you could introduce a blockchain system. In order to achieve full transparency in the presidential elections (parliament, senate, etc.), they can be held on blockchain. If the government of any country dares to take such a step, it will be possible to consider that these are the first 100% non-falsified elections in the history of mankind. The technological base is already there, the matter remains for the world leaders, but most likely they will not be quite happy about such prospects.

With the help of this technology, intermediaries can be removed from the chain of interaction between buyers and sellers of goods and services, which makes cooperation more profitable and effective. The technology of blockchain has a great future, many analysts compare its importance to humanity with the invention of the Internet. It will be able to fully reveal its potential in the third decade of the 21st century.

2. Cryptocurrency types and their difference from other payment systems

As it has already been mentioned above, cryptocurrencies became the first mass applications that were built on the basis of the blockchain technology. The first one was Bitcoin, but in almost 10 years since its creation, about 2500 different coins and tokens having different value and performing different functions have been released. Some coins are designed purely for making payments, others can act as the domestic currency of a certain application, the third are able to guarantee dividends from developers for their holders. Types of coins are too numerous, you can read more about them in our article.

The main difference between cryptocurrency and traditional payment services is their decentralization. That is, coins do not have a specific center that can monitor the network. All participants of the system interact on the principle of equality, where each member of the community acts as a user and as a server at the same time.

Advantages over traditional payment systems:

  • Significant reduction of the commission and time of international transfers due to the absence of intermediaries. For example, a transcontinental payment for $99 million was recently made in the Litecoin network, the commission was only 40 cents, and the transaction took 10 minutes. Within the traditional payment systems, this would require 7-10 working days, and commission fees would be at least $100k.
  • Anonymity. Digital technologies both give us freedom and take it from us. Using a MasterCard or Visa, a person stops being anonymous. If you want, you can track the entire history of his/her purchases, his/her location, etc. Some cryptocurrencies guarantee total anonymity.
  • Absence of outside intervention. Any bank can freeze its client’s funds if it sees it fit. Since cryptocurrencies do not have a single center, such intervention in the work of individual wallets is almost impossible. Of course, it all depends on the type of wallet. For example, you can freeze your account at the exchange, but if the coins are on a hardware cold wallet, no one else has access to it, except its owner.

3. How are coins extracted?

Bitcoin is often compared with precious metals, in particular gold, because they have a number of similar characteristics:

  • limited amount (a total of 21 million BTC will be released);
  • the need for extraction (mining) and the gradual increase in the complexity of this process.

Some coins (such as Bitcoin, Ethereum, Litecoin, etc.) need to be mined. Let’s discuss what kind of process it is and how it works. So, coins are awarded to the miners who installed a certain amount of computer equipment and provided it for the system’s operation. You can obtain cryptocurrency in a variety of ways, even using a PC, but you should not wait for any serious earnings in this case. Miners often use more powerful hardware, such as video cards or ASICs. The computing power of miners ensures the operation of the system and the timely conduct of transactions.

4. Forecasts for the cryptocurrency market

It is worth noting that the market is now in a phase of deep correction in comparison with its peak values, which were observed in the January this year. But even if you look at the annual chart, you can see that the assets are showing good growth (about 250%). According to the two-year chart, the growth rate of capitalization is 21760%, and so on. So do not panic like most of the media. The fact is that there are many people who invested in late November-December 2017. Their outrage is justified, they lost 70-80% of their contributions, but it is unfair to make a conclusion from this that the cryptocurrency industry is collapsing.

Many analysts predict growth for this year by 20-30 times of today’s value. In general, analyzing the cryptocurrency market is a rather difficult task, and nobody can say for sure what rate will be at the end of the year. Let’s just say, there are no fundamental reasons for the collapse. As soon as the news background improves, the market should start to grow and possibly even reach new historical highs.

5. Conclusion

Many people interpret the technology of blockchain as a transactional-only network, but this is not true. The application spheres of this technology are numerous. Cryptocurrency is only the tip of the iceberg. Analysts predict the widespread introduction of decentralized applications in the 2020s.
