Universal USB Installer

 Universal USB Installer is a free universal program for creating bootable USB flash drives. You can download this universal utility from this link. There is no paid version. The whole essence of the program is reflected in the name - the utility is universal. You can make bootable USB sticks with Windows and Linux. This also applies to the operation of the program itself, only owners of devices on Mac OS will not be able to use it. There is also the ability to download the image directly from the network, if we are talking about Linux. There is a standard procedure for Windows. Of the settings, it is worth highlighting the choice of the file system and formatting the drive before recording. The disadvantages include the fact that the program does not work with the XP version or lower, and the program does not have the Russian language. Brief instructions for creating a bootable USB flash drive In "Step 1" select the desired version of the OS that you plan to burn to a USB fl...

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.
