White-Book

Programming in a narrow sense is the creation of code. Speaking of developing as a whole, programming includes different stages and involves diverse specialists (not only developers). Any process of project implementation starts with an analysis. Certain research helps to find out the client’s true purposes and needs, figure out the market condition and competitors. It’s obligatory in order to create a solution, which would meet all your requirements and the expectations of your audience.

Unfortunately, when it comes to creating a modern system, the list of specialists is drastically reduced. The main reasons are a lack of competence, high workload, inflated budget, and so on. White-Book understands all your pains, so we offer professional development services that don&rsquo;t cost an arm and a leg.

Provision of programming services: web development, creation of mobile systems

<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Digital money has become a part of our life. They are gradually displacing traditional banknotes due to several reasons. First, it is easier to carry a credit card than a wallet. Second, the government gets control over all transactions that guarantees budget receipts. Third, digital money is cheaper because there is no need to issue it. So, the prevalence of such a type of money has generated high demand for different online payment systems.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">What is a Payment System?
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">A payment system is a software, which includes numerous rules and procedures to transmit a certain amount of money between persons. The most popular examples are PayPal, SWIFT, Qiwi, Payoneer, and Western Union. It&rsquo;s worth noting the software may differ in features and operating principles but the result you get is usually the same: receiving money from another person. Let's take a look at one of the above services, namely SWIFT.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">An Example of How the Software Works

The system is managed by local processes and operation centers. In order to transfer a certain sum, a financial establishment creates a financial message to another market player. It consists of a title, text, and &ldquo;trailer&rdquo; (special code). First, the message is sent to a regional processor and then to an operation center for processing and verification. If everything is okay, the request is going to the addressee.

There are numerous solutions but it doesn&rsquo;t mean you&rsquo;ll definitely find one that would meet all your requirements. Our team is able to create a stunning crypto wallet to cover your needs.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">What is a Crypto Wallet?
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">If you decided to buy cryptocurrencies, first of all, you should create a crypto wallet. Usually, it is software integrated with certain crypto platforms. A small remark: we say "usually" because there are also offline (&ldquo;cold&rdquo; type) wallets on the market. They exist in the form of small gadgets (like a USB flash drive) and don&rsquo;t require an Internet connection.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The integration with each cryptocurrency in the market is impossible because new ones appear every day. This is why the services related to crypto wallets creation are in demand.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">It&rsquo;s worth mentioning that cryptocurrencies aren&rsquo;t stored in crypto wallets: your assets are actually stored in the blockchain. Any wallet includes only tokens (special keys, which provide you with access to your crypto coins). It&rsquo;s like a bank card, which gives you access to the bank account.
<span style="font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Particularities of Crypto Wallets

It is a password, which you enter to make a transfer;

<li dir="ltr" style="list-style-type: disc; font-size: 11pt; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre;" aria-level="1">

Unfortunately, the convenience of their use is sometimes questionable. If you lose your physical wallet, it means you don&rsquo;t have your assets anymore.
