WampServer 3 web server build overview

 Note! It is not recommended to use a web server collection as a platform for hosting sites both on the Internet and in corporate networks, i.e. they are created for local development and testing only. This is a recommendation from the developers of any web server build. WampServer is a free build of a web server, i.e. platform for web development under the Windows operating system. This assembly includes all the necessary software for creating dynamic web applications (sites), namely: Apache web server, PHP programming language, MySQL DBMS and other auxiliary software, such as phpMyAdmin. For those who don't know WAMP is an acronym for "Windows, Apache, MySQL and PHP" i.e. a word consisting of the first letters of the listed applications. There is also LAMP, where L is Linux, and MAMP, where M is Mac OS. WampServer is available for both 32 bit and 64 bit Windows. The system tray icon acts as a control panel here, with the help of which (left-click) you can configure the ...

The history of the emergence of the PoW algorithm

The history of the emergence of the PoW algorithm

PoW is one of the oldest algorithms that was used in the creation of the very first Bitcoin cryptocurrency. The first description of the protocol appeared in 1993. As planned by the authors, he had to fight spam. And the algorithm performed this function. In 1997, Adam Back successfully launched the Hashcash project, which was based on the concept of PoW. Senders of letters, using the power of a PC, had to carry out billions of calculations that confirmed the truth of the subject of the letter. This solution blocked spam. From the technical side, it looks like hashing a selected range of data, for example, lines from a letter.

2 years after the launch of Hashcash, the term Proof-of-Work first appeared. During this period, the algorithm, like a mathematical captcha, solved several simple tasks that protected the system from spam and DDoS attacks. To perform operations, significant resources were not required, so the system worked smoothly.

In 2000, the developers decided to update the mechanism by introducing auxiliary functions into it. This required an increase in memory capacity and a revision of hardware requirements. The requirements of high processor speed have been replaced by large amounts of RAM. It was during this period that Bitcoin miners switched to powerful video cards.

The development of cryptocurrencies and the improvement of equipment have increased the load on the system and complicated the execution of tasks. The PoW algorithm literally began to "devour" electricity, which led to a decrease in rewards. Mining of popular cryptocurrencies became unprofitable. In 2012, the performance of the Bitcoin blockchain exceeded the energy consumption of the world's most powerful computer. After the advent of the PoS algorithm, Proof-of-Work began to fade into the background or be used in tandem. Today, the work done algorithm is used in projects that continue to issue tokens.
