How to use the EIA oil report in trading The content of the article What is an EIA report What data is published in the report How to use the report in trading Long term trading Short term trading Conclusion In this review, we will consider the weekly EIA report on the state of the oil industry, which has a strong influence on black gold quotes. Many traders closely follow his publications and use the information received when trading. What is an EIA report The Energy Information Administration, EIA, is a division of the US Department of Energy established in 1977. It is responsible for the objective collection of energy data, analysis and economic forecasts. Various reports are regularly published that provide information on energy-related topics. For example, reports on energy stocks, demand and prices. The United States is not only a major oil consumer (approximately 20% of world consumption), but also a leading oil producer. The balance of supply and demand in the US gives a rough ...

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.
