System requirements for installing Microsoft Visual C++ Redistributable Package 2015 Each version of the Microsoft Visual C ++ Redistributable Package will have its own system requirements, but since the 2015 version is the most current at the moment and it naturally has the highest system requirements, that's why we will consider them, but I will also touch on previous versions. 2015 version supports the following operating systems: Windows 10; Windows 7 Service Pack 1; Windows 8; Windows 8.1; Windows Server 2003 Service Pack 2; Windows Server 2008 R2 SP1; Windows Server 2008 Service Pack 2; Windows Server 2012; Windows Vista Service Pack 2; Windows XP Service Pack 3. If you have Windows 7, then, starting with Microsoft Visual C++ Redistributable Package 2012, you need to have Service Pack 1 installed, i.e. The 2012, 2013, and 2015 redistributables can only be installed on Windows 7 Service Pack 1. Equipment requirements: Processor with a clock speed of 1.6 GHz or more (in versio...

PoW mining difficulty
The difficulty of mining coins is measured by the number of computations required to add a block to the blockchain. Complexity is influenced by many factors: the aggregate of computing power, the number of users, the load on the network, etc. The complexity parameter is introduced so that computational tasks are not solved too quickly, otherwise this will lead to network problems.
In the Bitcoin network, blocks are generated on average every 10 minutes, so the difficulty increases automatically. A large number of network miners and the “absorption” of huge capacities led to the “screening out” of small miners. Initially, bitcoins could be mined on ordinary video cards, today this requires ASIC miners, which cost thousands of dollars.
The PoW algorithm is based on a mechanism that consists of 4 stages:
Generation of mathematical problems that require high power. When making each transaction, the miner must verify his identity. At the same time, the processing of one block can take several days, as in the Bitcoin network.
Creating a known result, which makes it easy to check the results of calculations. From a technical point of view, the results of PoW are similar to the answers to problems that are published in textbooks. The system checks the truth of complex and lengthy calculations in a few seconds.
Network users make transactions by sending a predetermined number of coins to encrypted addresses. Merged transactions form encrypted blocks
The truth of the blocks is checked by lengthy calculations. The user who first solved the problem receives a reward in the form of coins. Confirmed blocks are stored in the blockchain, while the system launches a new round of transactions. Each network node receives a copy for data synchronization.
The PoW algorithm generates tasks that have a set solution time, for each type of equipment there is a set interval. Such a mechanism maximizes the computing power of the miners. The total amount of computation required to add a new block to the chain is reflected in the mining difficulty metrics. At this stage of blockchain development, the complexity of mining automatically increases.
