Additional Earnings for Health Consultants by Blockchain
We live in an era of change. Great changes affect all aspects of people’s lives, including the most important area for any person, health care. Now, for almost all healthcare practitioners, amazing opportunities are opening up, previously available only for a few of them.

Now it’s very easy to open your own practice without all the known difficulties: without opening your office, without appointing hours of reception and waiting for customers, without advertising your office to attract clients.
In the Online Health Consultations System Doc in Pocket many habitual middlemen, such as banks, are replaced by an intermediary blockchain program that works on networked computers of consultants and their clients.
Thanks to the exclusion of the ‘human factor’ the System can function without possible human errors, without unnecessary loss of time and financial costs for salaries and with the protection of financial and other sensitive information.
Getting rid of banking services in the Doc in Pocket is possible due to the use of the DocCoin (DOC) cryptocurrency tokens. Cryptocurrency coins and tokens are invented specifically to get rid of middlemen bankers. And cryptocurrencies are a very important and rapidly developing part of modern life. The first cryptocurrency, Bitcoin (BTC), was introduced only about 10 years ago.
The other important part of the Online Health Consultations System Doc in Pocket is our smart contract.
A smart contract is, generally speaking, a program on a computer network designed to determine the rules for the exchange of any information between people using blockchain technologies. The smart contract replaces conventional contracts.
Such technologically advanced ‘cryptocurrency’ clients are people who value their time and the safety of their personal information, they are people responsible and wealthy, who take care of their health.
In addition, if such people like your services, they will be using them for the rest of their lives. Moving to another place of residence will not prevent them from contacting you for your help, because you can use the DocCoin (DOC) cryptocurrency token everywhere, it does not depend on any local currency and is available anywhere in the world where there is the Internet, and the Internet is almost everywhere nowadays.
So, the new group of customers will increase not only the amount, but also the stability of your income, and this will also give a push to the globalization of your services.
This advantage will complement the list of usual benefits of Doc in Pocket for practicing professionals: advising clients at a convenient time, increasing the number of people applying for consultations because of easy availability without leaving home.

Forward to the Future with DocCoin Cryptocurrency
You should think about purchasing a cryptocurrency DOC token and here's why.

The global changes that are underway now are affecting all aspects of people's lives, including the most important for everybody: health.


The most important and large-scale changes in health are connected with telemedicine and blockchain technology. For those who care about their health and who want to keep abreast of the latest advances in technological progress, they must necessarily become familiar with these new trends.
'Telemedicine' can be defined essentially as 'healthcare via the Internet', and 'blockchain technology' is a technology that uses computers interconnected to the network in order, wherever possible, to get rid of middlemen - people and companies, and replace them with a program distributed over these interconnected computers.
Online Consultation System Doc in Pocket is intended to unite consultants and their clients and to remove unnecessary intermediary from their community.
Remuneration for consultations in the Online Consultation System Doc in Pocket takes place thanks to the use of the DocCoin (DOC) cryptocurrency token.
Token is a cryptocurrency that is issued by a known company for openly declared rather narrow purpose, while 'cryptocurrency coin' (or 'simple cryptocurrency of old type') can be issued ('mined', 'created') by everyone in decentralized manner and then can be used instead of conventional currencies if it finds a community of users.
The DocCoin Token (DOC) is released on the basis of another token named 'Ethereum' or 'Ether' (ETH), which is designed specifically to be a base for releases of other tokens, and it is so popular that it is being mined even by a multibillionaire and co-founder of Google corporation.
In just about ten years of their history, after the appearance of Bitcoin (BTC) in 2009, the value of all cryptocurrencies has risen from zero to hundreds of billions of dollars, and two years ago, in 2016, it was only about a dozen billion. It's just a staggering growth in dozens of times in just about a couple of years.
Right before our very eyes blockchain revolution is taking place, and it will determine the future of mankind. And no matter how much bankers may argue with this, they are forced to deal with cryptocurrencies in spite of their negative attitude.
Say, recently the largest Russian bank announced that it will deal with cryptocurrencies despite the sharply negative attitude of the head of this bank, as, indeed, of all other banks.
The governments of the main countries are also against cryptocurrencies, but they cannot withstand their pressure and the will to live.
For example, the US government could not find a reason to prevent the Chicago Mercantile Exchange (code: CME, the largest in the world) from starting bitcoin futures trading, because for futures trading only a changing market rate is required, and Bitcoin has it.
Also, the largest companies are beginning to think about the blockchain. For example, Facebook has already formed a department that will do the development and research of the blockchain technology.
However, despite the overwhelming successes, the blockchain technology has a very large scope for further expansion and development, for example, their application in the healthcare sector lags behind the general trend, although health is a very important part of anybody's life.

Our company DocCoin is working to fill this regrettable gap.
We are sure that our cryptocurrency token DocCoin (DOC) will play a worthy part in the blockchain revolution that is taking place before our eyes.
It is the duty of all progressive people of goodwill, to support the future of mankind.

Trust is the main thing in human relationships of all kinds: working, personal or financial ones. Mutual trust is especially important when it comes to health. If a client does not trust a medical consultant, it is highly unlikely that the client will ask the consultant for treatment. So, how can a consultant earn this trust?

In the real healthcare world the trust can be earned by a doctor by his or her experience, knowledge, clients’ references or personal connections, but in the digital world the matter is much more complicated. Every day in the Internet millions of transactions with strangers maybe from another part of the planet are made. Why would somebody give a total stranger her or his money and personal information? There must be a good reason for this, and just having some references is not enough. People need a service to trust.

The answer to the question is simple, and this is online Health consultations System and smart contract developed by DocCoin specialists. This is an opportunity to fully protect both sides. This is a contract which cannot be violated whether intentionally or otherwise.
To make it simple, ‘smart contract’ is an algorithm for transmitting data reliably and confidentially, without any specific intermediaries (banks or government agencies) involved. Health services payments made by means of DocCoin cryptocurrency gives a client 100% confidentiality and full freedom of the payments from external control. Such highly reliable transactions are available thanks to Ethereum blockchain environment. Data transfer made by means of a smart contract is completely transparent, traceable and irreversible, but at the same time impersonal from outsiders. After a conclusion of a contract, neither party will be able to make changes to the data or change the conditions on their own, since all of the data are recorded in a chain. In this chain each block of data refers to the previous one, and so, nobody can remove the block from the chain. This is why the blockchain system is gaining popularity as the most secure and reliable data transmission mechanism, both for small companies and corporate giants.

However, no one is immune from disagreements and controversial issues. Conflicts happen, this is an integral part of any business and relationships between any buyer of services and a seller of the services, and in the case of online health consultations it means conflicts between a health consultant and a client.

When developing our smart contract software DocCoin specialists were taking this issue into account. If a consultation does not satisfy a client, instead of just confirming the payment the client can use an arbitration, and this way he will have an opportunity to challenge the payment. The DocCoin company has taken care of protection of clients and prestige of health consultants. Only those clinics that are truly professional and fully confident in their services’ quality are ready to provide clients with such guarantees, and, as we have already found out previously, guarantees equal trust.

After opening a dispute an appointed arbitrator will carefully investigate the case and will take an objective decision in favor of one of the parties.

It is noteworthy that in turn 100% advance payment protects the side of health consultants. If a consultation was provided at a professional level, then due to the terms of the transaction specified in the smart contract, the customer cannot refuse payment for the services provided. Besides, a client will not be able to send money to a health consultant who is offline, since the smart contract protocol requires confirmation of two parties. This will save clients a lot of red tape with returns of funds and losses of time for clarification.

By using DocCoin smart contract you get an opportunity to expand your business quickly and effortlessly by means of new technologies. You do not need to spend time and money on developing and implementing software, its maintenance and improvement. We offer a final product and assume all the responsibilities for its maintenance and security. We are so confident about our skills and about the efficiency of DocCoin smart contract that we offer you a year of our services for absolutely free of charge!



So, let’s list the advantages of DocCoin smart contract for online Health Consultations.
It guarantees for clients
- 100% protection of payments,
- confidentiality,
- transparency of payment terms and services,
- quick help of qualified specialists,
- convenient payment terms,
- the opportunity to challenge payment in arbitration.

For health consultants and counterparties:
- an additional source of income,
- new customers,
- quick confirmation of payment,
- 100% payment for services,
- free connection to smart contract,
- competitive advantage without significant efforts,
- the whole year of smart contract use for free of charge.

There is no doubt whatsoever that telemedicine is the future of health care. Let’s agree, that it is much more convenient to get a quick health consultant advice without leaving your house, than wasting your precious time standing in a long line, filling out a pile of papers etc.

Modern technologies and DocCoin smart contract among other things allow people to use the Internet resources safely and conveniently for not wasting their time.

In our modern, dynamically changing world, those will be ahead of others who can not only offer current services to their customers, but also to anticipate their wishes. This can be done only on condition of full trust, meaning here trust between client and consultant, buyer and seller, user and service. This trust can be ensured with the help of DocCoin smart contract!

GitHub Open Source - https://github.com/DocCoinICO/Blockchain_protocol_for_telehealth

The introduction of technology blockchain in the field of medicine has great prospects. It is a necessary step in the modern world where things change fast. Using blockchain for medical services opens the door to a new business-models, creates new analysis tools for health services and related fields. Blockchain system offers a universal set of tools for cryptographic data integrity assurance, standardised audit and decentralised contracts to access data. Nowadays medical services are a nightmare for all parties involved in healthcare sector. There are a number of global problems on the road to a healthy world. Compensations are calculated arbitrarily and in non-transparent way, fraud occurs more often. The patient's medical data might be lost and no one is responsible for the safety storage. Consultations with a highly qualified medical specialist from another country cost a lot of money. Expensive medical services make a simple medical help unaffordable for a lot of people around the world.

DocCoin is a global medical system developed on the blockchain basis and smart contract technology. This is the digital alternative in the healthcare world.

The purposes of DocCoin system are creating a more competitive environment in providing medical services and making access to high-quality medical services easier and more affordable for people around the world.

DocCoin was designed as a hybrid network, combining the speed of centralised networks and the reliability of decentralised networks due to hybrid schemes with independent index servers that synchronise information with each other.

What solutions does DocCoin offer to solve the main problems of healthcare world?

Service helps a client to select a specialist suitable for him as a client can choose qualification of a doctor, price and many other parameters that will allow a client to receive high-quality medical help. We keep your medical data secure and you can access it online in any time.
Why do we use smart contract technology?

Smart contract allows to secure each of the parties:

100% payment for services provided by doctors;
Secure storage of medical data for the patients;
Secure transfer of medical data to third parties.
Thanks to the decentralised network, DocCoin helps to reduce medical services costs and saves your time.

DocCoin expands the patient's capabilities allowing not only consultations with medical specialists and secure storage of medical data, but also referral to medical tests, prescriptions for medicines, sick leave certificates, communication with specialists from all over the world and remote health status monitoring.

The network effect of the service is achieved by scaling the number of users (including patients, doctors, insurance companies, hospitals and etc.) which gives the client wide variety of health specialists to choose from and strong demand for services provided by doctors thereby creating an eco-system of users that tends to scale.

Use of DocCoin in the field of medical services will increase the safety of the medical data, make it easier to access patient’s data, help to gather separated bases into a single one as well as make the interaction of patients, doctors, medical institutions and insurance companies more transparent and convenient. These are very important and valuable advantages that will bring blockchain and smart contract technologies into the future of healthcare services.

Cryptocurrency is the currency of the future!

Cryptocurrencies are currencies built on top of a network of personal computers interconnected via the Internet. The current currencies have come to existence only because of lack of the Internet and computers at the time.

Cryptocurrencies are set up and ready to replace the conventional ordinary currencies, which are now outdated and have outlived their time. The cryptocurrencies are a result of technical progress, and their spread and development cannot be stopped, the same way as technical progress cannot be stopped.
A very important thing about cryptocurrencies is that they allow establishing direct connections between people via Internet, and these direct connections make many middlemen unnecessary for public, even such popular ones as the bankers, those greedy people always pursuing their own interests.
With the help of cryptocurrencies ordinary people can exchange currencies using a program that is ‘not greedy’, ‘unselfish’ and reliable, because it is under public control, opened to everybody, and anyone can check the code of this program.
Cryptocurrencies are very convenient for people, and soon they will spread all over the computerized world and will be a very important part of it.
Health is very important in life, so the cryptocurrencies and the Internet must be used widely in the healthcare area, and this issue needs particular attention and should be set in high priority.
Telemedicine (or medicine on the Internet) is gaining momentum, although nowadays it consists mainly of remote health consultations and monitoring of a person's health through the Internet.
DocCoin company deals with Internet on-line health consultations system.

DocCoin token (abbreviated as DOC) is a cryptocurrency, or rather a cryptocurrency token, intended for rewarding health consultants for services provided by the means of the 'Doc in Pocket' application.
Generally speaking, the difference between a cryptocurrency and a cryptocurrency token is that a token is issued by some company with a pre-announced special purpose, and ‘cryptocurrency as not a tokens’ such as Bitcoin (BTC) is issued as a special kind of currencies issued in a decentralized manner, meaning without a central bank, by a spontaneous collective of volunteers.

With the help of the DocCoin token (DOC), clients can reward health consultants for services directly without a middlemen.
Firstly, direct payments are quick, because they occur without unwieldy banks' intermediation, which can transmit payments from one internal account to another before the money appears in the right place.
Secondly, payments by the DocCoin (DOC) token are reliable, because they are not affected by mistakes due to human nature, as they take place without the banks' intermediation meaning without people working in banks. Cryptocurrencies exclude the human factor.
Thirdly, payments with the use of the DocCoin (DOC) token are simple and understandable, because they take place according to the rules that people themselves negotiate with each other, without burdening themselves with the rules and restrictions of middlemen banks.
All these advantages of direct payments without intermediary banks are possessed by all crypto-currencies and tokens without exception, irrespective of the field of their application.
But the difference between DocCoin (DOC) and other cryptocurrencies and tokens is that it is intended to be a part of the online Health Consultations system ("telemedicine ecosystem"). It is specifically designed for remuneration for health advice and health services.
This means, among other things, that DocCoin (DOC) in some respects is similar to state currencies. As one can see, the currency of any state is obligatory for admission on all its territory in exchange for any goods and services. Similarly, the DocCoin token is intended to be the same, although in a limited area. The token will be accepted in health institutions with which the agreement will be signed in advance, in exchange for something tangible (health consultations).
DocCoin (DOC) is a cryptocurrency token, which is not only built on the basis of the most advanced technologies providing direct, fast and reliable payments, but, unlike many other cryptocurrencies, which no one is obliged to accept, it will be obligatory for admission in many (medical) institutions.

Development Report on August 2018

Our company DocCoin is working to create a ‘DocCoin Telemedicine Ecosystem “, which makes telemedicine (in other words ‘Internet medicine’) even more accessible and convenient than now, including allowing the use of cryptocurrency tokens.

Our programmers and designers work on the remote telemedicine consultations software system on the basis of blockchain technology, as well as on the relevant smart contract, on sites and their interfaces, and our managers are engaged in marketing and presentations, persistently look for and find partners and negotiate with them.

Over the past two months, we have made great progress on our promising path.
We would like to talk about some of our achievements.

The list of items changed recently looks like this:

site of the company,
smart contract,
- technical requirements for it,
- implementation,
- alpha testing, API key test of the smart contract to the service,
- security audit,
remote consultation system for telemedicine
- technical task for the system,
- its correction and audit,
- architecture solution,
- WEB-design,
- software implementation of the system:
 registration of participants,
 authorization,
 consultations,
 editing and deleting users profiles,
arbitration,
system control panel (back-office):
- authorization,
- statistics,
- connection with smart contract,
- directory;
presentation and marketing.
Let’s talk about this in more detail.


COMPANY WEBSITE
The design of the site of the company DocCoin (https://doc-coin.com/) was changed in such a way that it became even more pleasing to the eye, more convenient, more intuitive and friendly.

A famous poet N.A. Nekrasov once wrote:

“…words should be in crowded,
for thoughts there must be room … “

But on our website both thoughts and words have room, so that our texts look beautiful and are easy to read.

The content of the DocCoin website has also been changed.

In the section “Our products” a page with explanations about the smart contract was added.

This page was added for the convenience of people who are not familiar very much with smart contracts, with cryptocurrencies and, in general, with blockchain technology.

Generally speaking, cryptocurrencies and smart contracts are something very important and promising, we call on everyone to pay close attention to them, because they will soon replace conventional currencies and legal contracts and thereby change the lives of all humanity. We urge you to prepare for the big changes in advance, so that they do not catch you unawares.


SMART CONTRACT
In the DocCoin Telemedicine Ecosystem, the Ethereum (ETH) blockchain smart contract is responsible for the security of transactions for DocCoin (DOC) cryptocurrency token payment and generally determines the algorithm (the process of the transactions) itself.

Smart Contract Technical Requirements

All the variables and ‘objects’ necessary for writing the algorithm are defined, as well as all methods and functions, even the possibility of resolving disputes on the transaction.

The algorithm of the smart contract is written.

Implementation of Smart Contract Algorithm

The algorithm has been converted into code.

Smart Contract Alpha Testing and Smart Contract API Keys to Service Testing

When testing API keys for the DocCoin service, a number of shortcomings were identified:

a long response from the contract to the service;
unstable operation of the service when connecting with cloud databases;
all the consequences of the Internet connection termination were not taken into account;
there are problems with configuring the interaction between the service control panel and the back-office through API keys.
All the shortcomings identified in the testing process were corrected by programmers, and re-testing showed that the fixes do not introduce new problems into the system.

We are pleased to state that the testing was successful, that our system is rapidly approaching the ideal.


Smart Contract Security Audit Made by the Help of a Third-Party Company

Audit is, in this case, a form of software (smart contract) reliability testing, and not a check of our accounting department. Audit is needed here to check whether hackers can hack us. As expected, they can not, according to an independent expert assessment.

The following shortcomings were identified (see below a quote from the audit report):

1. Stylistics of the code. You need to decide on the style of writing. If the internal variables have the form with a bottom underscore at the beginning, then it is desirable to use this approach everywhere. However, in the code internal functions have underscores at the beginning, lower underscores at the end, and sometimes do not have it at all.

2. Contract DocCoin. If you position DocCoin as the ERC20 standard, it is desirable to initiate more functions from the standard. Of course, most likely it will be recognized as ERC20, but…

3. Of course, for mathematical calculations it is more appropriate to use safe libraries, but in your particular case they can be neglected. Because the actions are fixed. And if implemented, they will serve just for the beauty of the code and/or for helping paranoiacs sleep at night.

4. There is no fallback function. !!!Maybe!!! it should be added to the code.

The conclusion of the audit.

In terms of security there were no vulnerabilities found in the contract. Practically all of the comments are not critical.

REMOTE (ONLINE) CONSULTATIONS SYSTEM
The system provides convenient means for information exchange between telemedicine consultants and their clients. Among other things, it introduces the possibility of remuneration for telemedicine services by means of DocCoin (DOC) token, which is an ERC20 token.

The security of these transactions is the responsibility of the smart contract in the Ethereum (ETH) blockchain.
For owners of the system and their representatives (arbitrators), a special management and monitoring system is provided, namely the ‘DocCoin back office’.

Technical Specification, its Correction and Audit

The Technical specification had been prepared by a group of authors, then discussed in a wide range, then amended, then discussed again and so repeated until we achieved the desired result, and then this result has been audited.


Software Architecture Solution

We have adopted such an architectural solution that allows the designer to change the look of the site without affecting all programmers. With the chosen solution, specialists in narrow areas of programming and design solve their very important but narrow problems without interfering with each other. Professionals call it MVC pattern (Model-View-Controller).

Also, the system is built on the base of dividing into “frontend” and “backend”, and this allows programmers, not just programmers and designers working almost independently of each other.

These software architecture solutions are made with taking into account the following main requirements for the system: simplicity, flexibility, reliability, and convenience for users.

When the work of the collective of people is divided into parts (into ‘modules’) so that one part (‘module’) does not influence or has little effect on the other, then each part of the general system can be changed and improved independently of the other, and this makes the system easily changeable (this is about ‘flexibility’).

Also, splitting a large task into several smaller ones ensures the simplicity of the system, since small ‘modules’ are simpler than large ones.

Reliability at work is ensured by simplicity, for the simple breaks less often.

Reliability during system improvements is provided by the system flexibility, or, in other words, the ability to quickly, even unnoticed by the user, replace any new broken ‘module’ with the old, tested ones.

Generally speaking, in the virtual programming world, the older the program, the more reliable it is, although in the real world of material objects, on the contrary, the older the car, for example, the more unreliable it is.

If we could do this, then if we did something and tested it, we would not change anything in the system… But this is impossible, unfortunately, because the world is constantly changing, and we adapt to it. For example, we constantly improve our services for the users based on their new wishes and after the appearance of new opportunities for service.


1. DocCoinDB (MSSQL 2016) — Database for DocCoin service.

2. FrontEndAPI. ASP NET Web service with Soap/JSON interface.
In this API front end business logic is implemented.

3. BackEndAPI. ASP NET Web service with Soap/JSON interface, back office business logic is implemented.

4. FrontEnd web site (ASP NET MVC) — the main DocCoin project WEB site.

5. BackEnd web site (ASP NET MVC) — Control Panel of the service or back-office.

6. MobileAPI — API for mobile applications (release #2)

7. Mobile applications for IOS and Android.
Mobile clients of the service with built-in DocCoin wallet. (release #2)

WEB- design


In WEB-design there is a lot of tricks. It is known, for example, that the eyes of people when viewing a picture behave roughly like when reading a book. People of the European and related culture first of all instinctively look at the same place they look when reading the book, namely, in the upper left corner of an image.

Therefore, when designing, it is necessary to put the most important part of the whole in this particular place (the upper left corner).

According to our opinion, we put there the most important thing, and this is the ‘emblem’ and ‘motto’ (‘logo’) of our DocCoin company. It will be convenient for those looking at our site, if we place in the most prominent place, attracting attention at the very first moment, a brief explanation in a few words and lines what is the essence of all our work.

Generally speaking, user-friendliness, including intuitive clarity and simplicity of design, is the first requirement for WEB design or, in other words, for the appearance of a site intended for users. This part of the system is the first priority for us, in this area designers dictate their will to programmers, and they strictly obey designers who are closest to the end users, the most important people in our system.


System Implementation

The system (its version 1.0) is ready for beta-testing by medical consultants and consists of the following components:

User Registration (Client),
User Registration (Consultant),
Authorization (Clients & Consultants),
Consultation (Client’s Side),
Consultation (Consultant’s Side),
User Profile Editing,
User Profile Deleting,
Arbitration,
System Control Panel (Back-Office):
- Authorization,
- Statistics,
- Connection with Smart Contract
- Directories.
Let’s talk about this in more detail.

User Registration (Client) Algorithm Implemented


The user visits the site.
The user selects the ‘Registration’ option.
The user selects ‘Client’ system role option.
The user enters a name, email, password, password confirmation, age, height, weight.
The user agrees with the terms of service by checking a box next to the link to the agreement conditions, when clicking on the link the text of the offer contract with the user appears in a new window.
The user receives to his or her e-mail the information specified by him or her during registration and, additionally, a link for activating the account together with instructions for creating the Ethereum wallet and Metamask plug-in installation.
After filling out the form and confirming the email address the user hits the page with the list of registered consultants with a search option with the possibility of filtering by specialty, the user status is set to “Waiting for the DocCoin Wallet Binding”. A corresponding notification is set on the profile icon. In this status the user cannot use the services, and when selecting a consultant, a corresponding notification is displayed.
The user creates an Ethereum wallet (or uses previously created). Enter the profile and specify the wallet address in the corresponding field. After the form is closed its balance is displayed, the user status is changed to “Active”, the user has the opportunity to receive a consultation.
User Registration (Consultant). Algorithm Implemented


The user visits the site.
The user selects the ‘Registration’ option.
The user selects ‘Consultant’ system role option.
The user enters his or her name, email, password, password confirmation, LinkedIn link, age, specialty, optionally writes additional information about himself or herself in the “Additional Information about You” field in order to increase the chances of choosing him or her for consultations by clients.
The user agrees with the terms of service by checking a box next to the link to the agreement conditions, and when clicking on the link the full text of the offer contract appears.
The user receives to his or her e-mail the information specified by him or her during registration and, additionally, a link for activating the account together with instructions for creating the Ethereum wallet.
The user registers the wallet and installs Metamask. The address of the wallet is registered in the profile.
The user after activation of the account and saving the address of the ETH wallet gets on the screen of incoming proposals. If the wallet is not specified, a corresponding notification is displayed in the profile. Without a wallet, the consultation is blocked.
Authorization. Algorithm Implemented


The user visits the site.
The user selects the ‘Authorization’ option.
The user enters e-mail and password specified during registration.
The user, depending on his or her role, hits the following page:
The consultant gets to the page with video chat ‘on hold’.
The client hits the page with the list of consultants registered in the system with the possibility of filtering by specialty.
Consultation (from the Side of Client). Implemented Algorithm


The user is authorized for the access to the system.
The user selects a physician for consultation. If the funds in the client’s wallet are not sufficient for the services of this specialist, an appropriate error message is displayed.
The user makes payment for the service using the smart contract according to the tariff. The funds are transferred to the wallet of the smart contract.
The user receives a consultation.
The user, after receiving a report on the service provided, decides his problem is solved or not and presses the “End” button of the consultation, invoking the corresponding smart contract method and signing the Metamask request by the client. The funds from the DocCoin purse contract are transferred to the consultant minus the system commission.
The user receives information (on the e-mail he or she specified during registration) about when, at what time and who consulted him with the reference to the consultant.
The user enters the page with a list of consultants registered in the system with the possibility of searching with the possibility of filtering by specialty.
The user receives a report from the consultant about the most recent consultation (to the e-mail specified by him when registering) with a link to the page with buttons “Satisfied with Consultation” and “Arbitration”. When you click on a link from the email, you are asked to confirm the transaction using the Metamask client. Funds are transferred to the account of the consultant. If the “Arbitration” button is pressed, the status of the transaction is changed to “The Arbitrator”, and a form for filling in the claim for the service is opened, stored in the database. The arbitrator is informed of a new problem deal in the back office.
Consultation (from the Side of Consultant). Implemented Algorithm

The user is authorized for the access to the system.
The user enters the page of video chat in ‘on hold’ status;
When the client selects the user as a consultant, the user is notified by the system about changing the client’s ‘on hold’ status to the status of ‘waiting for payment for the consultation’.
After the client pays for the consultation, the user is notified by the system about the beginning of the consultation. A video chat is started.
The user conducts a consultation.
The user decides that the client’s issue is resolved and presses the “End Consultation” button.
The user receives information (on the email he or she specified during registration) about when, at what time and who consulted him with the reference to the consultant.
The user enters the page with a report form with the following fields:
- Reason for the Consultation;
- Possible Diseases;
- Recommendations for Prophylaxis.
The user sends the form, confirms the execution of the contract in the blockchain, invokes the corresponding method, signs the request to Metamask. The system automatically sends the form to the email specified by the client during registration, and also sends a duplicatition to the Consultant.
The user enters the page with video chat in ‘on hold’ status.
Editing the User Profile. Implemented Algorithm


The user is already logged in.
The user selects the ‘Edit Profile’ option.
The user hits the page with the fields filled in at registration.
The user changes the data at his discretion and presses the “Save” button
The user, depending on his or her role, hits the following page:
The consultant gets to the page with video chat ‘on hold’;
The client hits the page with the list of consultants registered in the system with the possibility of filtering by specialty
Deleting of User Profile. Implemented Algorithm

The user is already logged in.
The user selects the ‘Edit Profile’ option.
The user hits the page with the fields filled in at the time of registration.
The user selects the ‘Delete Profile’ option.
The user is asked to confirm or refuse to delete the Profile.
The user confirms deletion of the Profile.
The user is redirected to the page with an alert about the deleting of his data from the system with a link to the main page.
The user is notified about the removal of his data from the system at the email addresses he specified when registering.
Arbitratration. Implemented Algorithm


From the Side of the Client

The client is dissatisfied with the consultation. Instead of the button “The Service is Rendered”, the client presses the “Arbitration” button.
A form is displayed, where the client describes the claim.
The claim is retained in the system, the transaction in the smart contract is transferred to the “Arbitration” status. At the same time, the consultant is asked to fill out the form of a response to the claim for this transaction, the form contains the client’s explanations.
From the Side of the Arbiter.

The arbitrator, who was automatically appointed by the system for this transaction, receives in the profile and on the email a notification about the receipt of the disputed transaction.
The arbitrator analyzes the client’s claims and the explanations of the consultant and decides whether to return the funds to the client or transfer funds to the consultant.
The solution is recorded in the smart contract by calling the appropriate method.
Note: The system can be configured in such a way that all transactions after the description of claims to the consultant will be automatically resolved in favor of the client, but in the case of 3 consecutive transactions with a similar outcome, the user will be blocked by the system until the cause of the situation is clarified.

DocCoin Team

Telemedicine is, to put it shortly, ‘healthcare via the Internet’, and not at all "medicine on television", as one might think after hearing the name ‘telemedicine’.

https://c.radikal.ru/c04/1807/bc/211a349753f7t.jpg


That is, if you receive, for example, an advice of a medical consultant via Skype, or some medical student listens to a lecture on a webinar this is ‘telemedicine’.
 
One may define it this way: telemedicine is the use of telecommunication and information technology to provide health care from a distance, i.e. sometimes telemedicine is called ‘distance medicine’, although, probably, it would be better to call it ‘Internet medicine’.

Anyway, this term is quite new and not settled. It arose dozens of years ago at the time when the Internet did not exist, when the TV was advanced technology, when the display of a medical operation on TV seemed a miracle of technology.

Since then technology has developed very much.

Imagine, for example, that you are wearing small wireless sensors that continuously send data about your health to a medical consultant who can contact you at any time and give you an advice, say, to rest or to take a pill. This is especially valuable for chronic patients or for rehabilitation after a serious illness.
 
Or imagine that you are lying on an operating table in a local hospital, and the operation is done by a professor from Switzerland, operating surgical knives via the Internet.
 
The availability of medicine and its quality is increasing dramatically, and the price is falling dramatically also. There is no need to go to Switzerland for an operation, for instance, and this is a big saving at least on tickets.
 
But telemedicine, like any new thing, has, of course, its shortcomings and does not help to immediately get rid of good old face-to-face treatment, and, as always, disadvantages are an extension of advantages.

For instance, the Internet is good, of course, but what if the Internet connection is interrupted in the middle of an operation? Or what if a hacker interferes? Such risks are absolutely unacceptable here.
 
And one more important thing: it is difficult to teach and encourage current medical consultants to use telemedicine. Generally speaking, doctors are very conservative, they are extremely reluctant to accept something new.
 
But, despite all the difficulties, the future belongs to telemedicine.
One can see it from the fact that this is a very fast growing area:
the world's average growth over the past 3 years has been approximately 20% per year, and according to some studies currently about 7 million people worldwide use telemedicine, and in 2013 there were only 350,000, although the majority of telemedicine users is located in the USA, Europe and developed countries of Southeast Asia.
 
If talking about money, the telemedicine market measured in tens of billions of dollars, and according to some expert estimates, it will reach about $40 billion in the coming years.
In the last year of 2017
- in the US, more than $4.7 billions were invested in telemedicine,
- 70% of US employers offered telemedicine services to their employees.
 
Clients have a cautious attitude toward innovation too. Judging by the polls, only 65% of users would prefer video-consultation with a doctor to a conventional face-to-face visit to a clinic.

But these are just obstacles to overcome.

To make the future of planetary telemedicine (‘Internet medicine’) come faster, direct transactions using cryptocurrencies are required, as cryptocurrencies transactions are more convenient than cash or bank-based ones.
 
For medical transactions via the Internet one could use Bitcoin (BTC), the very first and still the most popular cryptocurrency or some other well-known cryptocurrency coins or tokens, but DocCoin company offers another solution.

Specifically for telemedicine DocCoin company issues a special cryptocurrency, or, speaking more precisely, a special token, DocCoin (DOC).

For reference: Cryptocurrency is computer currency coin that is used for direct transactions between people via the Internet without an intermediation of banks.
A token is not just a cryptocurrency coin, but a type of cryptocurrency issued by a known company for some special purpose. Unlike tokens, Bitcoin and other similar cryptocurrency coins are issued without a special purpose, as a special (decentralized) type of currency. Such cryptocurrencies are issued by communities of volunteers, who, generally speaking, may not be known to anyone and are not even familiar with each other.

DocCoin (DOC) is a token that was issued to remunerate medical consultants for services in telemedicine, mainly for remote medical consultations via the Internet.

Generally speaking, the list of telemedicine services may include (but is not limited to) the following:
- remote medical consultations of a specialist to a client or a colleague, with a possibility to ask questions and receive answers in real time;
- services of a medical sensor system for the collection of data on the status of a patient who is outside the hospital (at home or on the street), with the ability to respond quickly to changes in the patient's condition;
- services of mobile or portable medical complexes, capable of quickly transmitting data on the status of patients to medical facilities or medical professionals directly from the client's location, for example, even directly from a place of a car accident or syncope, which is very important for obtaining the fastest possible emergency assistance;
- streaming of surgical operations or lectures/seminars on medicine for teaching students and/or for sharing experiences between doctors.

In all these cases and not only in these ones DocCoin (DOC) token will help people to remunerate medical consultants for services without a intermediation of banks, the remunerations going quickly, simply and reliably.

With the help of the DocCoin (DOC) token telemedicine will probably cover the whole world earlier than without it. The DocCoin (DOC) token will certainly help the worldwide future of advanced telemedicine to come sooner.

DocCoin Smart Contract is the Best Service You Can Trust in the Digital World

https://d.radikal.ru/d04/1807/bb/c82858812b1e.png

Trust is the main thing in human relationships of all kinds: working, personal or financial ones. Mutual trust is especially important when it comes to health. If a client does not trust a medical practitioner, it is highly unlikely that the client will ask the practitioner for treatment. So, how can a practitioner earn this trust?
In the real healthcare world the trust can be earned by a doctor by his or her experience, knowledge, clients’ references or personal connections, but in the digital world the matter is much more complicated. Every day in the Internet millions of transactions with strangers maybe from another part of the planet are made. Why would somebody give a total stranger her or his money and personal information? There must be a good reason for this, and just having some references is not enough. People need a service to trust.

The answer to the question is simple, and this is telemedicine smart contract developed by DocCoin specialists. This is an opportunity to fully protect both sides. This is a contract which cannot be violated whether intentionally or otherwise.
To make it simple, ‘smart contract’ is an algorithm for transmitting data reliably and confidentially, without any specific intermediaries (banks or government agencies) involved. Medical services payments made by means of DocCoin cryptocurrency gives a client 100% confidentiality and full freedom of the payments from external control. Such highly reliable transactions are available thanks to Ethereum blockchain environment. Data transfer made by means of a smart contract is completely transparent, traceable and irreversible, but at the same time impersonal from outsiders. After a conclusion of a contract, neither party will be able to make changes to the data or change the conditions on their own, since all of the data are recorded in a chain. In this chain each block of data refers to the previous one, and so, nobody can remove the block from the chain. This is why the blockchain system is gaining popularity as the most secure and reliable data transmission mechanism, both for small companies and corporate giants.

However, no one is immune from disagreements and controversial issues. Conflicts happen, this is an integral part of any business and relationships between any buyer of services and a seller of the services, and in the case of telemedicine it means conflicts between a medical practitioner and a client.

When developing our smart contract software DocCoin specialists were taking this issue into account. If a consultation does not satisfy a client, instead of just confirming the payment the client can use an arbitration, and this way he will have an opportunity to challenge the payment. The DocCoin company has taken care of protection of clients and prestige of medical practitioners. Only those clinics that are truly professional and fully confident in their services’ quality are ready to provide clients with such guarantees, and, as we have already found out previously, guarantees equal trust.

After opening a dispute an appointed arbitrator will carefully investigate the case and will take an objective decision in favor of one of the parties.

It is noteworthy that in turn 100% advance payment protects the side of medical practitioners. If a consultation was provided at a professional level, then due to the terms of the transaction specified in the smart contract, the customer cannot refuse payment for the services provided. Besides, a client will not be able to send money to a medical practitioner who is offline, since the smart contract protocol requires confirmation of two parties. This will save clients a lot of red tape with returns of funds and losses of time for clarification.

By using DocCoin smart contract you get an opportunity to expand your business quickly and effortlessly by means of new technologies. You do not need to spend time and money on developing and implementing software, its maintenance and improvement. We offer a final product and assume all the responsibilities for its maintenance and security. We are so confident about our skills and about the efficiency of DocCoin smart contract that we offer you a year of our services for absolutely free of charge!

https://a.radikal.ru/a00/1807/bc/59791c416ed8.jpg

So, let’s list the advantages of DocCoin smart contract for telemedicine.
It guarantees for clients
- 100% protection of payments,
- confidentiality,
- transparency of payment terms and services,
- quick help of qualified specialists,
- convenient payment terms,
- the opportunity to challenge payment in arbitration.

For medical practitioners and counterparties:
- an additional source of income,
- new customers,
- quick confirmation of payment,
- 100% payment for services,
- free connection to smart contract,
- competitive advantage without significant efforts,
- the whole year of smart contract use for free of charge.

There is no doubt whatsoever that telemedicine is the future of health care. Let’s agree, that it is much more convenient to get a quick medical consultant advice without leaving your house, than wasting your precious time standing in a long line, filling out a pile of papers etc.

Modern technologies and DocCoin smart contract among other things allow people to use the Internet resources safely and conveniently for not wasting their time.

In our modern, dynamically changing world, those will be ahead of others who can not only offer current services to their customers, but also to anticipate their wishes. This can be done only on condition of full trust, meaning here trust between client and consultant, buyer and seller, user and service. This trust can be ensured with the help of DocCoin smart contract!

The introduction of technology blockchain in the field of medicine has great prospects. It is
a necessary step in the modern world where things change fast. Using blockchain for medical services opens the door to a new business-models, creates new analysis tools for health services and related fields. Blockchain system offers a universal set of tools for cryptographic data integrity assurance, standardized audit and decentralized contracts to access data. Nowadays medical services are a nightmare for all parties involved in healthcare sector. There are a number of global problems on the road to a healthy world. Compensations are calculated arbitrarily and in non-transparent way, fraud occurs more often. The patient's medical data might be lost and no one is responsible for the safety storage. Consultations with a highly qualified medical specialist from another country cost a lot of money. Expensive medical services make a simple medical help unaffordable for a lot of people around the world.
DocCoin is a global medical system developed on the blockchain basis and smart contract technology. This is the digital alternative in the healthcare world.
The purposes of DocCoin system are creating a more competitive environment in providing medical services and making access to high-quality medical services easier and more affordable for people around the world. .
DocCoin was designed as a hybrid network, combining the speed of centralized networks
and the reliability of decentralized networks due to hybrid schemes with independent
index servers that synchronize information with each other.
What solutions does DocCoin offer to solve the main problems of healthcare world?
Service helps a client to select a specialist suitable for him as a client can choose qualification of a doctor, price and many other parameters that will allow a client to receive high-quality medical help. We keep your medical data secure and you can access it online in any time.
Why do we use smart contract technology?
Smart contract allows to secure each of the parties:
100% payment for services provided by doctors;
 Secure storage of medical data for the patients;
 Secure transfer of medical data to third parties.
Thanks to the decentralized network, DocCoin helps to reduce medical services costs and saves your time.
DocCoin expands the patient's capabilities allowing not only consultations with medical specialists and secure storage of medical data, but also referral to medical tests, prescriptions for medicines, sick leave certificates, communication with specialists from all over the world and remote health status monitoring.
The network effect of the service is achieved by scaling the number of users (including patients, doctors, insurance companies, hospitals and etc.) which gives the client wide variety of health specialists to choose from and strong demand for services provided by doctors thereby creating an eco-system of users that tends to scale.
Use of DocCoin in the field of medical services will increase the safety of the medical data, make it easier to access patient’s data, help to gather separated bases into a single one as well as make the interaction of patients, doctors, medical institutions and insurance companies more transparent and convenient. These are very important and valuable advantages that will bring blockchain and smart contract technologies into the future of healthcare services.
