Recently, there has been widespread talk of Blockchain technology. However, not even all people in the financial sector understand what it is. What can we say about ordinary people. The only thing that many people know about blockchain is the presence of a relationship with bitcoins. In simple words, when it appeared, how it looks and works, we spoke in detail about what bitcoin is in the last issue.

We could not allow such a gap in your knowledge. Therefore, we tried to expose most of the nuances in the publication. Do not waste time, start reading right now!

About what blockchain technology is for and what it is in simple words, how the blockchain system works and what advantages it has - read this article

1. What is blockchain in simple words - an overview of the concept + advantages of Blockchain technology

Studying any topic, you should first understand the terminology. Word Blockchain comes from an English phrase, the translation of which sounds like Block chain. It is this phrase that conveys the basic meaning of the concept quite well.

Blockchain (from English blockchain) - this is technology, which involves the collection of information in a sequential chain of blocks with protection using cryptographic ciphers. At the same time, data chains are not stored on a separate server, but are present simultaneously on all devices connected to the network.

Blockchain is a self-contained system, the functioning of which does not require third parties. Moreover, the system under consideration is extremely open. In the process of creating a blockchain, the main goal of the developers was to avoid intermediaries.

Experts say that the widespread use of blockchain technology will lead to significant changes in the information world. This is explained quite simply: decentralized data storage allows you to protect them from unauthorized changes,eg hacking, counterfeiting or any control.

Another important plus (+) technology is that intermediaries (financial organizations, payment systems) are no longer needed for any data transfer operations. All information is transmitted using the protocol. peer-2-peer, that is, directly from one user to another.

All participants in the system have the opportunity to obtain information about the history of operations, as well as about other participants. Moreover, all system data is stored simultaneously in all network devices.

Access to funds located on the wallet in the blockchain system is available only to its owner. Money is not placed with intermediaries, which are usually banks. Due to this, transactions are not under anyone’s control.

In more detail about what a blockchain wallet is and how to open it, we wrote in a separate publication.

Blockchain is able to secure any operations that involve the risk of one of the participants in the transaction refusing to fulfill its obligations. That is why the list of areas in which the technology under consideration is used is constantly growing.

Blockchain technology can be applied:

  1. when conducting financial transactions with money;
  2. at the conclusion of contracts and agreements;
  3. in the course of various commercial transactions;
  4. upon purchase of goods and services;
  5. when exchanging confidential information;
  6. for registration of insurance policies;
  7. to protect property rights, as well as transfer them to the new owner;
  8. personal data management;
  9. to ensure the security of intellectual property;
  10. assistance in creating archives of documents.

To connect the individual blocks of information among themselves, complex mathematical algorithms are used. Each subsequent data link is attached strictly to the previous one. He is assigned unique signature, and also added time stamp.

Adding a block must be confirmed by all network participants. This procedure leads to the fact that the registry on all devices is automatically updated. It turns out that the appearance of each link leads to the appearance of data about it in all information databases.

Important! Hacking the network will only work if you gain access at least half of the devices integrated into it. Naturally, it is technically almost impossible to accomplish this.

The attitude to the latest blockchain technology is absolutely ambiguous today. Government bodies fear that the lack of control over financial transactions will lead to the prosperity of illegal trade, eg weapons, drugs and people.

Finance companies on the one hand, they are afraid, because the lack of the need to use the services of intermediaries can leave them without work, at the same time, the blockchain interests them from the point of view of application in activities.

Over 40 large banking organizations have created consortiumcalled R3. Its purpose is a large-scale study of blockchain. The consortium members are sure that the new technology cannot be perceived as an unconditional evil for banking organizations.

On the contrary the use of blockchain allows significantly reduce costs. Banks intend to transfer interbank payments to a new technology and abandon the one used today Swift.

In Russia Blockchain technology, as well as cryptocurrencies, are treated differently. The government is constantly changing its mind - sometimes it calls for the study of new technologies, sometimes it intends to ban them. In simple words, we talked about cryptocurrency in simple words in one of our issues.

The Ministry of Finance proposes to criminalize those who use cryptocurrencies. At the same time, the head of Sberbank and the head of the Central Bank publicly express their support for modern technologies.

In fact, It has long been proven that there is no point resisting progress and modern technology. Blockchain has already appeared and is working. It is important to learn how to live with this and turn technology for personal and universal benefit.

The main advantages of blockchain technology: no central server; fast and accurate transactions; transaction transparency; availability of a full copy of the database; data encryption

Blockchain Technology Benefits

Blockchain Technologyhas a large number meritswhich every day attract the attention of an increasing number of people.

Already today there is an opinion that the new data storage technology will lead to the emergence of a new Internet - internet values. This is due to the significant advantages of the blockchain, which will be described below.

Advantage 1. No central server

Blockchain is a brand new way to store important information. The data in the Blockchain system is stored decentralized, there is no single storage. Thanks to this, it is impossible to control information.

To change even one block of information, unrealistically huge capacities will be required. Information is stored on all devices connected in a network at the same time. Therefore, they remain virtually invulnerable.

Until the advent of new technology, absolutely all information was stored on servers. Including data on monetary transactions, sales transactions, any other actions. Meanwhile, any server can be hacked. As a result, fraudsters can not only gain access to confidential information, but also change it.

Advantage 2. High speed and accuracy of operations

Lack of centralization, as well as built-in protection against unauthorized access, help to carry out operations with high speed and accuracy, refusing the services of intermediaries (banking organizations, payment systems, notaries, exchangers) The authenticity of the operations carried out is verified and confirmed by the network participants themselves.

It is on these principles that are based smart or smart contracts. They are executedonly in the event that certain conditions are met. Breaking such an agreement or changing its terms retroactively is not possible.

In contrast to them, traditional agreements establish obligations of the parties to the transaction, terms of execution, as well as the consequences of non-compliance. Moreover, the traditional contract is always fraught with the risk that someone will violate the conditions.

Advantage 3. Transparency of operations

Blockchain network is in state continuous monitoring. This means that she periodically checks herself.

For this purpose, an audit of a digital system is used. Moreover, absolutely all information contained within the system remains transparent, data on all transactions is available to all participants.

Advantage 4. A full copy of the information base is stored by each participant in the system

Each user of the system has on his computer a copy of the information base, which is regularly updated. Therefore, network participants do not have to coordinate data with each other. As soon as a new operation is added to the blockchain, this is confirmed by each user.

However, it is impossible to change not only a single block, but also their sequence. Access to a specific information link is carried out using the key, which is available only to the one to whom it belongs.

Advantage 5. Information Encryption

The information from which the link is formed is automatically encrypted. Full protection of stored information provides cryptography.

Thanks to hashing, Blockchain guarantees the invariability of the entire chain of operations. At the same time, availability digital signatures, as well as personal keys 2types protect data inside the link from unauthorized access.

The main methods of using blockchain technologies (storing digital certificates, organizing the DNS system, transactions with various goods, identification and confirmation of access rights, network management, operations with property rights, confirmation of copyrights, information management, organization of electronic voting)

2. Where is blockchain used? 9 technology applications

Blockchain is increasingly being introduced into digital as well as real-world areas of activity. Theoretically, the technology can be used in any field where there is a risk of being deceived or receiving incorrect data due to errors in the transmission of information. It is also possible to use the technology in the absence of trust between partners.

Blocks allow you to secure operations by creating smart deals. Broadcast password carried out only subject to pre-agreed conditions. If they do not occur, each of the parties to the transaction remains at its own.

Below are the options in which the use of blockchain is by far the most effective.

Option 1. For storing digital certificates

Blockchain technology provides reliable data protection from illegal studying, spreading, as well as changes. Due to the fact that certificates are stored on the network, it is impossible to get unauthorized access to them.

It will also not be possible to intercept illegally access keysbelonging to the participants in the system.

Option 2. Organization of the DNS system

Blockchain helps make name distribution within networks completely secure. Thanks to this, any DDoS attacks (hacker) cease to threaten absolutely all network members.

Option 3. Transactions with various goods

Risk always accompanies transactions with precious metals, raw materials, as well as in large batches of various goods. If you use blockchain technology as well as cryptocurrencies during such transactions, the danger can be reduced to a minimum.

Option 4. Identification, as well as confirmation of access rights

Some major corporations are already using Blockchain technology to identify employees as well as customers.

In addition, the system is used to provide access to internal information to those who are entitled to it. This method of verification of rights turned out to be more reliable and cheaper.

Option 5. Network Management

When administering various networks, Blockchain advocates storage a list of users, as well as passwords that are invulnerable.

Using technology in this case helps protect servers and networks from hacker attacks. It also solves another important task - it frees up the need for administration.

Option 6. Carrying out operations with property rights

You can confirm and transfer ownership almost instantlyusing blockchain technology. It is enough for the owner to enter data on the change of rights in his link so that they immediately become available in all blocks of the system.

Option 7. Confirmation of the rights of the author

Blockchain technology can help authors protect their intellectual property rights. Now creative products can be made inaccessible to outsiders.

Subsequently, if a desire arises to transfer intellectual property rights to third parties, smart deal. This will completely protect yourself.

Option 8. Information Management

Not only financial transactions, but also any information requires its owner to comply with all privacy rules. Using Blockchain technology, data is decentralized.

It’s worth considering that when storing information simultaneously on a huge number of computers illegal alteration, falsification or deletion becomes practically impossible.

This option of data protection and storage is significantly cheaperthan traditional. You will not have to spend money not only on expensive equipment, but also on protecting data from unauthorized access.

Option 9. Organization of electronic voting

Organization of electronic voting using blockchain allows to achieve it anonymity, as well as reliability of the results.

Since it is impossible to change the information in the links, it is not possible to rig the results after the end of voting.


To simplify the procedure for comparing blockchain use cases, the basic information about them is presented in the table.

Table of blockchain technology use cases, their practical application:

Use caseWhat givesCurrent state
1Digital Certificate StorageAllows you to protect certificates from unauthorized actionsActively used
2DNS organizationDomain Name ProtectionSeveral examples developed and operational.

8Information managementSecure storage of informationUsed by foreign organizations
9Organization of electronic votingUnable to fake voting resultsPracticed by some network projects

3. How blockchain technology works - 5 stages of the system

It is far from always easy to understand how that which cannot be seen works. But we will try to help sort this out.

How does blockchain technology work: 1) creating a transaction and transferring it to the network; 2) transfer of operation to a P2P network; 3) Validation; 4) Transaction confirmation; 5) Adding a new block to the circuit

Below is presented Blockchain technology operation algorithm using cryptocurrency operations as an example. In fact, this digital money is only a block of information, so the principle of action can be applied to any operations based on blockchain technologies.

Stage number 1. Transmission of a decision on an operation (transaction) to the network

Owner bitcoin wallet makes a decision to pay with the monetary units stored in it for a certain product, transferring funds to the account of the online store.

After the decision is made, information about it is transmitted to the network, which consists of a large number of blocks.

Stage number 2. Receiving a transaction by a P2P network

A transaction using special algorithms is transmitted to a computer network. After that happens auto cryptographic encryption launch information received, the formation of a separate unique link.

This block contains link to the previous block, as well as time stamp.

Stage number 3. Confirmation Procedure

Information about the link created at the previous stage is transmitted for the purpose of checking to all nodes included in the system. Each of them enters the information received into the existing information base. The chain is being updated. At the same time, information about this is entered into the general register.

The above procedure for confirming the operation, as well as the status of the user is called validation.

Stage number 4. Confirmation of the operation, as well as the creation of a new information link

As soon as confirmation passes, the new information link takes its own unique place in the blockchain. From this moment, the block acts as a full-fledged part of the chain.

Each participant in the chain can receive transaction data, however, the information contained in the link is available. only to anyone who has from him password.

Stage number 5. One block chain extension

At the last stage, the recipient of the operation receives the transferred bitcoins to his wallet. Confirmation of this is carried out by both parties to the transaction.

It is important to understand! Each operation acts as a separate unit, which is a full chain link. Its reliability and uniqueness is confirmed by all nodes.


An example of the operation of Blockchain technology in the field of cryptocurrency

The presented algorithm can be transferred to any operation in any field of application of the blockchain. We hope that the technology operation procedure has become more clear.

4. Popular blockchain projects - TOP-8 of the most promising

Anyone can invest in startups that work on the basis of Blockchain technology. Today there are a lot of such projects and their number is constantly growing. The advantages of technology are revealed in the process of solving various problems that arise in real life.

Should be considered, that blockchain is in a state of early development today. Therefore, the profit from such investments can be huge.

Below are described the most promising projectsbased on the blockchain base.

1) Ethereum

Ethereum represents the second project in terms of capitalization after Bitcoin. Ethereum is based on the idea of ​​using smart contracts, that is, program codes in a blockchain environment that are automatically executed under certain conditions.

The popularity of the Ethereum project is explained by the high degree of flexibility of the smart contracts underlying it. Modern developers do not need to independently invent how the block chain will be implemented. With smart contracts, you can quickly and easily create an add-on to your existing Ethereum system.

The key minus (-) Ethereum smart contracts has become that there are no intelligible models of cooperation with part of the real processes. For example, the program code does not allow tracking the physical transfer of goods.

2) NEM

Nem - A project by Japanese developers, which is very similar to Ethereum. NEM is designed to develop projects based on the principles of blockchain.

Main advantage Nem is to high transaction processing speed. The system confirms actions within a few seconds.

This allowed the NEM project to become a serious competitor. bitcoin. Moreover, bitcoin has recently had difficulties with the speed, as well as the cost of operations.

Unlike Bitcoin, which is mainly focused on the transfer of individuals among themselves, NEM has a much greater throughput and allows billions of transactions in the interbank market.

The high speed of NEM makes it attractive to banking and other financial companies.

At the same time, NEM developers continue to work on even greater expansion of bandwidth, as well as cheaper operations.

3) Ripple

Ripple - Another Japanese project, which is one of the most important competitors of NEM. Ripple helps banking organizations significantly reduce⇓ transaction costsas well as speed up transaction processing.

Testing the project by serious financial institutions confirms that Ripple has great potential.

However, the project has significant disadvantage. The fact is that assets in Ripple are not distributed transparently, half of the capital is controlled by developers.

4) Sia

Sia It is a decentralized cloud storage. Unlike traditional similar services, which place user information on their own servers, the project proposes the placement of data on the principle of blockchain technology (storing encrypted information on multiple independent computers).

The mechanism of the Sia project is as follows:

  1. Owners of computers, as well as servers scattered around the world, create on their disk an area called node. This part of the memory is leased. The income of the owner of the node is determined not only by its size, but also by the stability of the work, as well as by the degree of data safety.
  2. A project participant buys a subscription and uploads information files to the network. After that, reliable encryption and blocking. Links are loaded into the landlord nodes. At the same time, information is duplicated many times in case certain parts of the network are disconnected.
  3. With the help of smart contracts, after a certain period, remuneration is paid to the owners of disk space. In this case, a special currency is used - Siacoin.

Advantage The project is the cost of the subscription. She turned out below traditional storage costs more than 10 times. In addition, neither the police nor government agencies can demand the provision of information stored on the Sia network.

5) Dash

Dash It is digital money with improved anonymity and confidentiality.

Important! Recently, the principles of anonymization of cryptocurrencies have been called into question. It turned out that Bitcoin transactions can still be tracked.

In contrast to this Anonymity of operations conducted through Dash helps to remain unknown sender, as well as the recipient Money. This is provided at the network protocol level. Such functionality is extremely popular in conditions of total surveillance.

One more advantage Dash is an almost instant confirmation of operations. In addition, the project implements a promising model of management and self-financing.

6) Maidsafecoin

Maidsafecoin It offers users the infrastructure for running applications, as well as sites without the pressure of censorship.

The project participants are paid a fee for the provision of data storage services, as well as the power of computers.

The project maintains the confidentiality of absolutely all data. They do not track user actions, do not sell information about them to advertising agencies.

The purpose of the network is to guard against snooping. However, the project is in its infancy and is still managed by a centralized company.

7) Aragon

Aragon became one of the startups that showed the best result in the last year. The idea underlying the project is to create decentralized organizations.

This will allow you to get away from bureaucracy and paper. The activities of such companies are supposed to use exclusively digital data.

On the project website, you can try out the demo version of the program, which allows you to:

  • manage shares owned by the founders of the company;
  • vote on the principles of smart contracts;
  • raise money for the development of activities;
  • distribute responsibilities among employees.

It is assumed that the first users of Aragon will be small companies engaged in innovation. In the near future, developers plan to significantly expand the functionality of the system.

It is also expected to introduce dispute resolution systems. This will help to connect smart contracts with business processes taking place in reality. Using Aragon leads to a significant reduction in company costs.

8) Bitshares

Bitshares - a project whose purpose is electronic trade in property. His resources are also used to prove ownership. Moreover, the project allows you to fix the value of the property in more familiar units, for example in dollars or gold.

In the future, it is anticipated that trading on Bitshares may take on a more global scale. It is likely that this project will become a decentralized trading platform for any kind of objects.


Today blockchain technology is in its infancy. It is not easy for investors to understand which of the current projects will develop and make a profit.

Do not forget that new technology, in the wake of the growing interest in it of many people, can be used scammerswho want to fraudulently earn money on this.

Before investing in any blockchain project, it is important to carefully study the following information about it:

  • read the development concept outlined in Whitepaper;
  • highlight the advantages of a startup over other similar projects;
  • understand the technical features;
  • make sure that news on the development of the project is regularly published;
  • Find out who the developer is.

The last step should be analysis of the technical parameters of the project, including duration of work, capitalization, reasons for the change in value.

When investing in blockchain projects, it is important to follow the principles of diversification. Ideally, you should distribute the money between several projects.

Some ideas (ways) of making money on blockchain technologies

5. How to make money on the blockchain - 5 ways to make money

In the recent past, it was not entirely clear how blockchain could be used. Today it has become clear that these technologies are very promising. By investing in them, you can get a significant profit. You can find out what investments are and what types of investments can be found in one of the articles of the Rich Pro magazine.

The following are the simplest and most understandable business ideas (ways to make money)based on blockchain technology.

Method 1. Production and sale of tokens (ICO), their exchange for cryptocurrency

Today on the Internet at the same time there are several hundred different cryptocurrencies. Anyone who has the right to create and put into circulation their own electronic currency.

If you do not go into details, the cryptocurrency creation process includes only 2 stages:

  1. The ICO team sells digital tokens. They are devices used to identify participants in the payment system, as well as to ensure the security of information. Payment for tokens can be made as popular cryptocurrenciesand real money (they are also called fiat).
  2. The procedure for putting into circulation a new cryptocurrency is ongoing. From this moment they begin to use it inside the project as a calculation tool, sell it on specialized exchanges.

When implementing the type of business in question important build trust, as well as arouse enthusiasm from future investors. For this, it is necessary that the project being created be legal and as open as possible.

Worth considering! By functionality, tokens are similar to stocks. Investors can expect to receive dividends in the future. However Tokens do not provide their owners with the right to own a part of the created project.

Naturally, investors buy tokens in order to receive high and quick income.

We also advise you to read our article about investing on the Internet, which tells how and where to start investing in networks.

Method 2. Implementation of the Blockchain system in the activities of organizations

It is important to understand that the programs and algorithms used in the technologies under consideration are costly, and the process of their implementation quite complicated. However, successful companies never go against advanced technologies.

On the contrary Many leading organizations strive to implement blockchain in their own activities today. In this way they get noticeable advantage compared with competitors, because sooner or later the introduction of blockchain technologies will occur in most major financial organizations and other companies.

Owners of developments based on Blockchain, having connections with technologists of large financial companies, they can quite successfully sell their achievements.

It is important to draw their attention to the fact that the proposed projects allow get rid of intermediaries in the course of business. This will help save huge amounts annually.

But do not forget about the essentiallack of similar projects. The fact is that Bitcoin, like other cryptocurrencies, is not popular with financial companies. This is due to the fact that digital money is still not recognized by the state and in any case, you have to exchange bitcoins and other cryptocurrencies for real money.

Method 3. Cryptocurrency lending

The number of active users of the blockchain is constantly growing. This leads to an increase in the popularity of loans in cryptocurrencies.

Today, several decentralized platforms have already been created and are successfully operating, the tasks of which include issuing loans in cryptocurrency. Customers of such services on borrowed funds or acquire ICO tokenseither trade on cryptocurrency exchanges. About how to trade bitcoins on the exchange, read the article here.

Method 4. Registration of various types of rights

The popularity of registration services copyright, as well as legal rights through the use of Blockchain is constantly growing. Meanwhile, the number of platforms offering to do this is still small.

Take note! If in the near future to create a business for registration of rights and engage in its high-quality promotion, after a certain time you can get a successful and popular service.

Method 5. Creation of cryptocurrency exchanges and payment services

Today, the network already has several dozen exchanges offering to carry out all kinds of operations with cryptocurrencies. Every day, a huge number of transactions are carried out on each of them.

Each trading operation brings income to the exchange owners. Moreover, the commission is obtained essentially only for providing a trading platform.

The number of services that allow payments in cryptocurrencies is also growing steadily. At the same time, the demand for their services is growing. Today even companies operating outside the network accept such monetary units as payment.


In fact, blockchain technologies today are at the stage of active growth in popularity. This is the best time to create a business based on them. Gradually, the market will become saturated, and creating a truly popular project will be more difficult.

We also recommend that you read the article - "Business on the Internet."

9. Misconceptions about the Blockchain system - 5 main myths 📛

Blockchain undoubtedly has a huge number of advantages, but it still cannot be called. perfect.

When using technology in practice, various difficulties and limitations can often arise.

Moreover, about blockchain appeared a huge number of myths. Some of them are firmly embedded in the minds of users and prevent the correct understanding of the principles of building a blockchain. Below are the most popular blockchain misconceptions.

1) Blockchain is eternal

There is an opinion that the data stored in the blocks of the circuit remain there forever. Theoretically it is, but in practice this is not possible. Today, the increase in file space does not keep pace with the growth in the volume of chain links.

Blockchain wallet user needs to free up file storage space the base. Moreover, in order to use cryptocurrency, you will have to download it to your computer special applications.

It will take a lot of time, require free space. You can, of course, use an online wallet, but it will no longer be a pure blockchain.

2) Cryptocurrency will completely replace real currency
