Setting up Viber on a computer

 Setting up Viber on a computer We launch Viber, in Windows this can be done using a shortcut on the desktop, and in Linux Mint using “Menu->Internet->Viber” (the process of setting up Viber in Windows and Linux is no different). After starting on the first window, we answer “Yes”, since in this article we are considering the option when Viber is already on the phone, therefore we answer “Yes”. Then enter the phone number and click Continue. After that, a QR code will be displayed on the next window, and a QR code scanner will start on the phone. You read this code accordingly and that's it, Viber activation on your computer is completed. Next, click the "Open Viber" button. When you first start Viber on your computer, the program will offer to synchronize your chat history, click the "Synchronization" button, a window will open on your phone at this time in which you need to confirm the synchronization, i.e. press the "Start" button. That's ...

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.
