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 ...

Relationship between algorithm and cryptocurrency space

 Relationship between algorithm and cryptocurrency space


In the very first virtual currency, PoW is needed to achieve consensus in the network. Since at any given time for each user there can be several versions of the blockchain at once, the algorithm determines which one is reliable. To implement his idea, Nakamoto took advantage of the developments of the Hashcash project mentioned above, slightly modifying the finished function (adding a mechanism for changing its complexity, which depends on the total computing power of all network nodes). The finished function is called SHA-256.



The PoW algorithm is necessary for checking by network nodes that the miner has performed calculations. The latter performs calculations of complex algorithms, as a result of which a new generated block (“cell”) is added to the block chain, storing a certain number of records of completed transactions. The proof-of-work mechanism attempts to find the hash of the node header, which contains a reference to the previous "cell" and the total value of all operations placed in the newly generated node. Hash exponents correspond to the set degree.
