Review of Smart Contract Technology: What Is It Used For and How to Work With It?

smart contract technology

If not all the representatives of the crypto world heard about smart contracts, then probably most of them did. Therefore, it is so important to know the details of the work of this innovative technology of “smart contracts”, the concept of which was announced a couple of decades ago, but was not fully realized in 2014. What is it, how can it be applied in practice, and what future, thanks to smart contracts, is the industry waiting for?

1. What is a smart contract?

A familiar look at the financial system changed in 2008 with the appearance of the first cryptocurrency, a coin that has a value that is not confirmed by physical assets. But year 2014 gave the mankind a way to regulate payments without the participation of intermediaries and such guarantors as lawyers, courts and other traditional institutions.

Intelligent contracts were enabled in practice by the blockchain. What is the essence of innovation? Smart-contracts are something like program code containing a complete package of information about an upcoming transaction. Logic is the simplest: it does not require the participation of a third party. If Mr. X wishes to transfer a certain number of coins to Mr. Y for a particular service, the transaction will occur automatically if the parties comply with the prescribed conditions. If they fail to be complied by any of the parties, the transaction will not take place.

Smart contracts do not provide for the presence and even potential participation in the relations of the parties of any arbitrator. Everything is extremely logical and simple – a smart contract, in fact, is no different from the usual contract, in which there are:

  • signatures of the parties that confirmed their agreement with the terms of the contract;
  • the subject of the contract;
  • the conditions under which the contract will be executed.

2. What is the advantage of smart contracts in practice?

The most important thing is the lack of the need to attract guarantors for the fulfillment of obligations. The parties do not need to apply to the notary, exchange and other third parties who by their signature / seal will attest to the intentions and obligations of the contract’s parties. Also, technology implies full transparency and security of information stored in the blockchain. As a result, the parties receive their benefits under the contract and do not pay the commission to intermediaries.

3. How to work with smart contracts?

In this regard, all the issues are fully answered by the Ethereum, known to all the crypto community. In it, the filling of a smart contract is intuitively understandable and accessible to everyone. On the official site Ethereum you need to download the purse, come up with your electronic signature and key. You can not only apply ready-to-use templates, but create code yourself.

4. What is a smart contract for practice?

The security guarantee provided by this technology allows investors not to risk when investing assets in the ICO. The investor had the opportunity not to rely on the success promised by the developers of the new coin, but to “insure” their funds by writing in the contract the condition for an automatic refund.

Technology is attractive in various areas, where contractual relations between the parties arise. Banks, companies involved in insurance, logistics, etc. are interested in it.

5. How reliable is a smart contract?

Since a smart contract is a program code, it is not without possible shortcomings. They can be associated with the complexity of its independent compilation, not always sufficient flexibility of the blockchain and insufficient scalability.

It should be noted that, in the event of an error in the contract, there are no methods for regulating the dispute. Everything is done by the program, and the court has no tools to evaluate the propriety of its incorrect work.

6. Conclusion

The technology of smart contracts has great potential. In fact, they can be used in absolutely any sphere of life. But in order to make smart contracts become commonplace, it’s still necessary to do a huge amount of work. To date, the most reliable and secure platform for entering into smart contracts is Ethereum.

Bitcoin Mining: How Are the Most Popular Coins Mined Today?

How to mine BTС today?

Quite a lot of people really managed to make a fortune out of Bitcoin mining. And many still manage to do so today. In this article, The Coin Shark will tell what mining is, how the most popular cryptocurrency is mined today, when the latest Bitcoin will be mined, what are the prospects of the digital currency mining industry and other things that every crypto-enthusiast is interested in.

  3. How many Bitcoins can be mined and what’s the time period for that?
  4. Types of Bitcoin mining
  5. Prospects of Bitcoin mining
  6. Conclusion 

1. What is mining?

Today, even those who are not really familiar with cryptocurrencies have definitely heard something about mining. However, it is not always clear what it actually is.

Mining is a computing operation. In fact, this is a kind of an attempt to solve a complex mathematical problem. The particular “X” that must be found as the result of the calculations is called a hash. If it is successfully found a new block is generated in the cryptocurrency blockchain. A block is a structural unit where the information about cryptocurrency transactions is recorded. It is sometimes not that easy to get all those terms, so let`s take a look at a rather simple example: a block is a kind of a banknote. Any banknote is a legal tender only if it looks in a certain way. It has a special design, watermarks, other security features, particular density, etc. Each banknote must meet certain specified parameters, otherwise, you will not manage to buy something for it and it will be just a piece of paper. The same thing with cryptocurrencies! Transactions are confirmed by being recorded into the blocks, and the blocks must be valid, must have a particular form. To meet this form, to generate a valid block, a hash with required parameters should be found as the result of computing operations. And that is exactly what miners are responsible for!

2. How is Bitcoin mined?

Bitcoin is a Proof-of-Work algorithm-based digital currency, that is why BTC is mineable. Proof of work actually means that transactions are confirmed, and the blocks are generated only if a certain work is done – new coins are issued only when one has managed to find the hash and create a new valid block. Every new block is generated approximately once every ten minutes. The Bitcoin code is written in such a way that, depending on the computing power in the network, the difficulty of the hash varies. In other words, the more powerful the miners are, the more difficult it is for them to find the hash. That is how the system maintains the balance between the available computing power and the complexity of the calculations. It does not matter whether only several personal computers are engaged in Bitcoin mining (as it was in 2009) or huge industrial mining farms (as it is happening today) – it will always take approximately ten minutes to generate every new block.

So, when miners do their calculations successfully and manage to find the hash, they are rewarded. This reward used to be as huge as 50 BTC. However, back then the number of coins was not actually a significant fortune. According to the Bitcoin code, this reward decreases by half every 210 thousand blocks. Since each block of Bitcoin is generated in about 10 minutes, it takes about four years to get 210 thousand blocks. So, every four years the reward is reduced by half. In 2012, there was the first reduction from 50 BTC to 25. The next reduction took place in 2016. Today miners get 12.5 Bitcoins for each generated block.

3. How many Bitcoins can be mined and what’s the time period for that?

It is only possible to mine a total of 21 million BTC. This maximum amount of cryptocurrency is provided by its programming code. First of all, this limitation is designed to prevent inflation and preserve the value of Bitcoin. Actually, those things are usually valuable, that have a limited supply, and if Bitcoin had an unlimited emission, like Ethereum and some other virtual currencies, it would have been potentially subject to inflation. As of mid-October 2018, according to coinmarketcap, the number of BTC coins in circulation reached 17,332,325, which means that only a bit more than 3.5 million coins remain to be mined. It would seem not a big deal – almost all Bitcoins have already been mined! But truth is, it will take more than a century to mine the remaining coins!

So, let’s see how long will it take for miners to get all Bitcoins. To calculate this, we should make several mathematical operations. Of course, these operations are not as complicated as those required to find Bitcoin hash. The computing power of your calculator will be enough! So that is what we have:

The reward is reduced by half every 210 thousand blocks (approximately once every four years). Accordingly, the number of coins issued will decrease every four years. So, 10.5 million BTC was issued during the first “four-year cycle”, when the reward for each block was 50 BTC. Then the number of coins is reduced by half with each cycle. According to this formula, the very last BTC will be mined about the year 2140! Interestingly, in the first seven “four-year cycles”, miners will extract 99% of the coins, and it will take more than a century to get the remaining 1%.

4. Types of Bitcoin mining

About ten years ago, when the first peer-to-peer decentralized payment system with a cryptographically protected digital cash (yep, it’s all about Bitcoin) was launched, there was only one, or perhaps several miners, in the network. Probably it was an ordinary PC or laptop owned by Satoshi Nakamoto – the mysterious Bitcoin developer – and maybe some other PCs owned by those involved in the development of Bitcoin. So initially users were able to mine Bitcoin using their own devices. The computing power of their processors was enough to perform necessary calculations and find Bitcoin hash. This type of mining was called CPU-mining. However, with the growing popularity of Bitcoin, more and more people joined the system, the load and difficulty increased, and eventually, it became clear that even the most powerful PC had not enough power to mine Bitcoin effectively. A casual user with his laptop was left behind. And the reason is that a probability of getting a reward is equal to the ratio of your individual computing power to the power of the entire network. So a new solution was found – users started mining Bitcoins using the computing power of video cards. That new type of mining was called GPU-mining. Several video cards were connected to a computer and the entire powerful device used special software to mine BTC. Today, a number of cryptocurrencies can still be mined using processors or video cards, but this is not working out with Bitcoin. To be able to find Bitcoin has users should make really complex calculations and special high-performance devices are required. These are ASIC-miners – a special equipment with high computing power and price.

Today users who have special equipment for BTC mining combine their computing power in special mining pools. Pools are groups of miners who use their computing power together and jointly perform the operations necessary to obtain Bitcoin hash. The probability of getting a reward is much higher than if users mine the cryptocurrency solely. This reward is then distributed in proportion to the computing power “invested” by each individual miner.

Moreover, cloud mining is also relatively popular. This, in fact, means that a user simply rents computing power from owners of large mining farms, who are often the manufacturers of mining equipment. Despite the fact that today this type of mining is gradually becoming less attractive, it still has its advantages – users do not need to buy equipment, place it, set up, maintain its operation, update hardware, pay for electricity, etc.

5. Prospects of Bitcoin mining

Many believe that the mining era is almost over and there are some reasons for this. After all, as we have already figured out, even the cryptocurrency code itself provides a reduction of the reward. If Bitcoin rate does not increase significantly, nobody will be interested in running expensive mining equipment and earning a couple of thousand satoshi (1 satoshi is 0.00000001 BTC).

Today mining is a fairly centralized industry with and it is rather difficult for beginners to join it. Especially for those who do not have a lot of money. Even owners of huge industrial mining farms experience some problems. For example, some of them realize that the equipment they used in 2017 cannot provide the same profitability in 2018. Today BTC mining is largely controlled by mining pools one hand and owners of huge industrial mining farms on the other and this tendency for mining to become more centralized is likely here to stay.

6. Conclusion

So, Bitcoin mining is not a “gold rush” anymore. The increased difficulty made it way more centralized and way less available for casual users. Today, mining still provides big profit for those who own huge mining farms or at least some high-performance equipment. The Bitcoin rate is far from the historical maximum, but nevertheless, it remains quite significant, and most importantly, according to many experts, has prospects for an even greater increase. However, today it is practically impossible to make money on mining without big preliminary investments. Mining prospects depend on the rate of cryptocurrency, and on the other hand, are also predetermined by the Bitcoin programming code itself. However, this predetermination can be defined differently. Yes, the reward is reduced every four years, so mining can become less appealing in the future. But this reduction can be compensated if Bitcoin price increases. Anyway, today many crypto enthusiasts consider other mining options. Sometimes it is easier to mine other coins, and then, if desired, exchange them for Bitcoin. One thing is clear – the mining industry has been changing, and the time will tell,  what will happen to it in the medium term.

Roubini vs. Buterin: Why Did Their Conflict Reach Live Debates and What Does McAfee Have To Do With It?

The conflict between two titans of the financial world – Nouriel Roubini and Vitalik Buterin is gaining momentum.

Forbes editor Laura Shin invited famous personalities to move from Twitter skirmishes to real live debates. Roubini and Buterin refused to cooperate with Shin, but they did not abandon the idea to talk live.

Where did it start?

As we reported earlier, an American economist Nouriel Roubini expressed a tough view of decentralization and the creator of Ethereum, Vitalik Buterin, on the Twitter account comparing him with a dictator and saying that “Decentralization in crypto is a myth. It is a system more centralized than North Korea ”.

After Buterin replied to Roubini that the above mentioned statement  is not “a fair characterization”, a long verbal skirmish began with personal attacks:

Conflict development

The more time passes, the more disagreements appear. Arthur Hayes, one of the founders of BitMEX crypto exchange, joined this “dialogue”, proposing to hold a discussion and pay all costs. Nouriel Roubini answered to this proposition no less harshly than Buterin, calling BitMEX “a criminal scam”.

Nevertheless, Roubini wrote on Twitter that he would be happy to discuss with Buterin in live mode. To which Vitalik replied: “Yeah sure why not.” For this purpose, they chose their own moderator, Kevin Pham, who is known not to support either of the sides. Laura Shin’s proposal to become a moderator was rejected because Roubini  have no interest to interact with @laurashin as he considers her biased.

What’s next?

Such a prominent event in the crypto world could not be ignored by the well known crypto personalities. John McAfee, who likes to be in the heart of events, has comically commented on this situation on his Twitter page. We think McAfee would be a good moderator, he would definitely give a sting to this debate.

Jokes aside, such “verbal duels” should end sooner or later, and we hope the live debates will help the opponents understand each other and find a common language.

Vitalik Buterin Find the Term “Smart Contracts” Not Quite Appropriate

buterin doesn't like the name of smart contracts

The technology of smart contracts is undoubtedly an essential part of the Ethereum protocol. However, Vitalik Buterin now regrets having chosen such a name for his creation. Buterin believes that his word choice should have been more technical and “boring” in order to display the full potential of the technology.

Such a comment was caused by the statement of a Twitter user which said that the word “contract” sounds way too legal, whereas crypto should stay away from governmental regulation.

Recently, the founder of Ethereum has encountered a lot of criticism regarding the issue of decentralization.

We remind you:

Vitalik Buterin Has Been Attacked By Roubini

What is Ethereum Address (ETH address)?

This information will be useful for those readers who are the beginning of their way in the cryptocurrency world. In this article we will talk about such concept as Ethereum address, find out what it is necessary for, where you can find it and see it. So let’s get started.

  1. What is Ethereum address and what is it for?
  2. Difference between online and offline addresses
  3. Conclusion

1. What is Ethereum address and what is it necessary for?

To begin with, it should be noted that Ethereum is the second most popular and capitalized coin. It has significant differences from the flagship of the industry with a good sense of the word. Ethereum has a more advanced technological base. For example, Bitcoin, in fact, is only a payment system, and on the basis of Ethereum you can create your own coins and smart contracts. Ethereum is a platform from which, potentially, a great number of companies and individuals can operate.

So, we are over with the introductory part, now let’s get to the essence of today’s question. ETH address is a certain unique set of letters and numbers, with a help of which a specific wallet can be identified. It is necessary to transfer coins from one wallet to another. It can be easily shared, since knowing it doesn’t reveal any important information about the owner and the state of balance.

Only the owner can receive the address. To get it you have to run the wallet application on a computer or mobile device. Without any doubt, in the interface of any crypto wallet program (there is a large number of services for storing Ethereum) you will find a special button that will automatically generate the wallet address.

2. The difference between online and offline addresses

If you are just starting your crypto journey, then you probably do not know that there are different types of digital wallets. We will dig into this topic too deeply, but just describe the main points. More information about the classification of wallets can be found on our website. So, the wallets can be:

  • Online. These include web-wallets and personal accounts that are on the exchanges. This is the most insecure, but the most convenient way to store and exchange coins.
  • Desktop and mobile apps. These are so-called hot wallets. They are more secure than online solutions, but with their help it is no longer possible to make transfers so quickly.
  • Hardware wallets. They are the safest way to store coins, since it is virtually impossible to hack them and get access to assets. But they are very inconvenient for every day use. This type of wallet is ideal for long-term storage.

So, you can get an Ethereum address both online and conditionally offline, on a desktop or mobile wallet application. Сonditionally offline, because even if the wallet is physically located on the computer, you need access to the Internet to work correctly. There is no principal difference between online and offline addresses, the only thing is that coins will arrive either on an online wallet, or on a desktop or mobile application.

It is very important to use only official wallets for storing ETH or any other coin. Since they are best optimized for work with this or that blockchain, and also have more advanced level of security than a service that was developed by third-party developers.

3. Conclusion

Everything about cryptocurrency topic seems so complicated, but this is only at first glance. Of course, the wilds of cryptography and the operation of algorithms are not easy, but for ordinary users such information is absolutely useless. The knowledge that is necessary in order to use cryptocurrencies can be obtained by any average person in the shortest time possible .

So, in this article, we discussed what Ethereum address is and found out that this is only the identifier of a certain wallet and is needed to transfer coins from one account to another.

Bitcoin Investment: Should I Invest in Bitcoins?

Bitcoin currency has already been used as a kind of a fiat money alternative for about 9 years. It is relatively popular all around the world. The first digital currency has made many people go nuts following the impressive ups and dramatic downs of its exchange rate.

Today, in October 2018, the whole cryptocurrency industry is looking forward to observing a new crypto-“miracle”. Search engines are overflowed with all those “How to invest in cryptocurrency?”. And this is not particularly surprising. Traders and different investors who own a significant capital expect cryptocurrency to be a promising investment tool in the long term. And if we talk about cryptocurrency, that basically means Bitcoin. Well, of course, there is a number of altcoins that can be worth making investments, but the first digital currency is definitely the most popular one.  

People still talk about investing in Bitcoin and this topic is interesting for many traders, investors and casual users. So, let’s take a closer look at this issue.

How to invest in Bitcoin

Before making an investment, one should obviously choose the way he or she wants to get some BTC. First of all, it depends on financial capacities. There are indeed many different options to invest in Bitcoin, but we will focus on two main ways that are currently the most popular and probably also the most effective.

Option №1: Taking advantage of the rate differences as a way of BTC investing

You might have already come up with the question, why people are still interested in making investments in Bitcoin when it costs less than $7 thousand per a coin? Well, influencers, opinion leaders, independent experts, and different analysists are confident that we will soon observe another sustainable increase of Bitcoin rate. And that is why many people start thinking about investing in cryptocurrency to make money out of the rate differences.

But what is the way to do that? It is actually pretty simple. All you need is some basics of math. In fact, investors are not really sad about the fall of Bitcoin. Many of them are even happy, especially those who believe that the cryptocurrency has a great future ahead. Today, if a trader purchases a BTC for $6,5 thousand, he or she will manage to make a good profit, in case BTC rate increases. Some really expect it to rise up to $30 thousand, and in this case, it will really be a good bargain. The key point here is whether the rate increases or not, of course.

Option №2: BTC mining

Besides, users can invest the special equipment that is used to mine Bitcoin. You may already know, that each BTC is actually a kind of a reward, given for the performance of certain calculations, necessary to issue new coins. Today these calculations are rather complex and require special high-performance equipment called ASIC-miners. The more users are there in the system, the more difficult are these calculations. This is called Bitcoin difficulty and it ensures that it always takes around 10 minutes to create a new Bitcoin block.

Investing Bitcoin this way means that you can get a certain number of BTC and store it till the rates grow or exchange it for another digital currency like Ethereum.

However, you’d better do not think that these two investment options will bring you fast and easy profit. This is possible only if the cryptocurrency rate increases significantly and in the case of mining, if your equipment has enough performance.

By the way, here is one more option of BTC investing. It`s actually difficult to say that it is a comprehensive way to invest in the cryptocurrency, but, anyway, many people use it today.

Bitcoin faucets

These are special websites, where users can get a reward for making certain easy tasks, usually related to online advertising. These rewards are paid in satoshi. The thing is, that one BTC includes as many as 100 000 000 satoshi, so one satoshi is only 0,00000001 BTC. So it`s actually a tiny piece of the market`s largest cryptocurrency. Investing BTC using Bitcoin faucets is not really effective, as you may never manage to collect at least one single coin.

Is Bitcoin a good investment

Well, if you have already decided to invest in digital currencies then Bitcoin will probably be the best option. Not only this cryptocurrency is a market leader and the most popular digital coin, but also it has relatively good liquidity as compared to other virtual assets. Many cryptocurrency followers believe that Bitcoin has a potential to become the main means of payment in the future. However, there are also those who bet on other digital currencies, as well as those who do not consider virtual coins as an investment option at all.

By far it seems that the question is it worth investing in Bitcoin remains undetermined, so let’s make it a little bit more clear. Bitcoin is relatively anonymous, decentralized and has a limited number of coins available for mining. This is, in fact, why hundreds of thousands of cryptocurrency followers made their decision in favor of BTC.

Anonymity

Investors do not have to disclose their personal data. The information about each transaction is public and everyone can see the address of the cryptocurrency wallets of a sender and a receiver, as well as how many BTC were transferred. However, the information related to owners of cryptocurrency wallets is not disclosed, so the whole system is relatively anonymous.

Decentralization

Bitcoin worth investing, as it has a decentralized management, which means there is no single administrative center. Transactions are carried out directly between users in a peer-to-peer network. However, Bitcoin users still have to pay certain commission fees for transfers of their virtual assets, because every transaction is confirmed and recorded in the blockchain by miners who receive rewards for this. Today small transactions are often not effective at all, as the commission fee is rather big. However, if a transaction is large, the commission fee will be relatively low.

Limited number of coins

Is Bitcoin a safe investment –  “yes” is the answer of many people, who believe that a limited number of Bitcoins to be mined is a strong advantage of the digital currency. It will prevent BTC from inflation.

“Why should i invest in bitcoin?– you may ask. The answer will probably contain both pros and cons. And that`s because Bitcoin has some special features, which are:

  • 24/7 trades, that allow making investments at any time;
  • most indicators have a rather good quality;
  • high volatility;
  • possible positive prospects of cryptocurrencies and, as follows, positive expectations related to Bitcoin investments.

Bitcoin investment trust

The risk remains here almost all the time and no one can guarantee that your money is 100% safe. Here are several examples why it can be rather risky to make investments in the largest cryptocurrency by market capitalization. Yes, Bitcoin still has a decentralized management, however, in a certain way the system is getting more and more centralized. This risk of investing in cryptocurrency is related to the fact that BTC rate starts depending on cryptocurrency exchanges.

Moreover, the significant part of all Bitcoins is owned by those who are engaged in mining or lease out high-performance mining equipment. Making new Bitcoins requires really a lot of computing power and gets more and more expensive. The competition within the system increases and it is almost impossible for casual users to join Bitcoin mining. That is why many people have already switched for other digital currencies that are easier to mine and can be later exchanged for BTC.

In some cases, Bitcoin`s anonymity is also a risk. Anonymous deals can be used for money laundering, as there is no effective state regulation of cryptocurrency transactions.

How to invest in Bitcoin stock

There are special cryptocurrency funds, similar to mutual funds that exist in the world of bonds and stocks. These funds are managed by private parties and it influences the interest rate. For instance, some cryptocurrency funds provide 1-2% per day.

Bitcoin investment strategy

There are two main types of cryptocurrency investment strategy.

The first one: investors buy BTC and sell the cryptocurrency when its rate increases.

The second one: Bitcoin holders trade their digital assets on cryptocurrency exchanges. This strategy is very similar to Forex trading.

Minimum Bitcoin investment

Many people decide to invest in Bitcoin because they hope to get huge profits in the long term. So, even a small investment is considered to be rather promising by many cryptocurrency followers. Eventually, the smaller is an investment – the lower is the risk. But, on the other hand, a really small investment can just be useless. Anyway, how much to invest in Bitcoin remains an open question and everyone has their own opinion.

Who said users can only invest their money? It is also possible to get BTC for free by investing one`s intellectual work. Well, just a bit of BTC, to be honest. Special websites offer users the opportunity to earn satoshi – the smallest fraction of Bitcoin – for the performance of different easy tasks, usually related to advertising. These websites are called Bitcoin faucets.

The main advantage of such an option is that users do not have to invest a single penny to get a piece of BTC, however, the drawback is also rather significant – it will take a really long time to get at least one BTC.

Invest in Bitcoin mining

Mining is actually how new digital currency is issued. Making investments in Bitcoin mining means buying special mining equipment or renting it from different providers. Cloud cryptocurrency mining is also possible. These services lease out their mining equipment for users to rent a particular amount of processing power.

There are some experts who think that cloud mining is actually the best way to invest in Bitcoin, as users don`t have to purchase, set, maintain and update expensive mining equipment.  

Anyway, both traditional and cloud mining still require preliminary investments.

Bitcoin investment sites

Before making investments in Bitcoin, basically, before purchasing it, you should have a cryptocurrency wallet to store your digital assets. Today Bitcoin holders and those who want to join them are lucky to have a large variety of different cryptocurrency wallets. These are, for example, mobile, hardware, online, desktop, cold, and even paper wallets.

If you are planning regular digital currency investment, we recommend having a local hardware wallet. However, it actually depends on what is more convenient for you and what meets all your requirements and there is really a number of options you can choose from. Do not forget to activate your cryptocurrency wallet.  

Usually, Bitcoin is purchased on cryptocurrency exchanges. It is really important to choose the right one, so we recommend taking the following criteria into account:

  • a region, where the exchange is registered;
  • input and output, exchange, transfer options, etc. – basically, what you can do with your funds in a digital wallet;
  • commission fee level;
  • reputation;
  • security level.

This will help you figure out whether is it safe to invest in Bitcoin.
