What does it mean to mine Ethereum?
Mining is the process of creating a block of transactions to be added to the Ethereum blockchain. Miners essentially process pending transactions and are awarded block rewards in the form of Ether, the Ethereum network's native currency, for each block generated. Generating a block requires intensive computational work (or hashing power) due to the difficulty set by the Ethereum network protocol. This difficulty level is proportional to the total amount of computational power (also known as the total hashrate of the network) being used to mine Ethereum and serves as a way to secure the network from attacks as well as tuning the speed at which blocks (and block rewards) are generated. This system of using hashing power generated by costly computer hardware is known as Proof of Work (PoW).
Who can become a miner on the Ethereum network?
Technically, anyone is able to mine on the Ethereum network using their computer. However, not everyone is able to mine Ether profitably. In most cases, miners must purchase dedicated computer hardware in order to mine profitably. While it is true anyone can run the mining software on their computer, it is unlikely that the average computer would be able to earn enough block rewards to cover the associated costs of mining (See question below for more details).
What are the costs associated with mining?
Potential costs of the hardware necessary to build and maintain a mining rig
Electrical cost of powering the mining rig
If you are mining in a pool, mining pools fees typically charge a flat % fee of each block generated by the pool
Potential cost of equipment to support mining rig (ventilation, energy monitoring, electrical wiring, etc.)
Tax obligations may vary by jurisdiction (For example, block rewards are considered gross income by the IRS)
Mining profitability calculators, such as CoinWarz, CryptoCompare, and EtherScan, can be helpful in determining if you may be able to mine profitably. Note that mining calculators may not 100% accurate and it may be useful to compare and contrast several results.
Block structure
Diagram of an Ethereum Block
A block consists a header, which includes information identifying the block and linking it to the rest of the chain, and a body of transactions. Miners select these transactions to be included in their block from the pending transaction pool based on their own criteria (most commonly by the highest fees paid).
Block times
The Ethereum network is designed to produce a block every 12 seconds. Block times will vary based upon how long it takes miners to generate a hash that meets the required mining difficulty at that moment. 12 seconds was chosen as a time that is as fast as possible, but is at the same time substantially longer than network latency. A 2013 paper by Decker and Wattenhofer in Zurich measured Bitcoin network latency and determined that 12.6 seconds is the time it takes for a new block to propagate to 95% of nodes. The goal of the 12 second design is to allow the network to propagate blocks as fast as possible without causing miners to find a significant number of stale blocks.

Uncle Blocks
Uncle blocks are stale blocks that are included in the calculation of which chain is the "longest"; that is to say, not just the parent and further ancestors of a block, but also the stale descendants of the block's ancestor (in Ethereum jargon, "uncles") are added to the calculation of which block has the largest total proof of work backing it. Block rewards are given to stales: a stale block receives 87.5% of its base reward, and the nephew that includes the stale block receives the remaining 12.5%. Transaction fees, however, are not awarded to uncles.
Ethereum implements a simplified version of GHOST which only goes down seven levels. Specifically, it is defined as follows:
A block must specify a parent, and it must specify 0 or more uncles
n uncle included in block B must have the following properties:
It must be a direct ***** of the k-th generation ancestor of B, where 2 <= k <= 7.
It cannot be an ancestor of B
An uncle must be a valid block header, but does not need to be a previously verified or even valid block
An uncle must be different from all uncles included in previous blocks and all other uncles included in the same block (non-double-inclusion)
For every uncle U in block B, the miner of B gets an additional 3.125% added to its coinbase reward and the miner of U gets 93.75% of a standard coinbase reward.
This limited version of GHOST, with uncles includable only up to 7 generations, was used for two reasons. First, unlimited GHOST would include too many complications into the calculation of which uncles for a given block are valid. Second, unlimited GHOST with compensation as used in Ethereum removes the incentive for a miner to mine on the main chain and not the chain of a public attacker.

Well, Litecoin is able to process a maximum of 56 transactions per second! This makes it much faster than both Bitcoin and Ethereum put together! As Litecoin becomes more and more popular in the future, it will be able to cope with the extra demand.bitcoin king
A fixed amount of coins also means that inflation will not affect the overall value of the currency, unlike currencies such as the dollar, pound or euro. For forex traders who feel that a currency might drop in value, they may purchase Litecoins and hold on to their investment before selling back into their currency (hopefully at a profit). External influences (such as governments) can manipulate the value of their currency through inflation and quantitative easing, but the same cannot be done with Litecoin, making it more sustainable long term.Due to the fact that many ICOs intend to release their own tokens on the Ethereum network in the coming months, many expect to see Ethereum rise back up to its all-time high value and even pass it. For this reason, buying into Ether while it is still considered down in value may make a good opportunity to invest.биткоин bitcoin Financial derivatives and Stable-Value Currenciesbitcoin seed The loss, theft, or destruction of the hard drive where the bitcoins are stored123 bitcoin wikipedia ethereum монета ethereum instant bitcoin xpub bitcoin bitcoin руб diversify a small percentage of his portfolio, for example 1-2%, into cryptocurrencies like Bitcoin.

This risks the scarcity aspect of the commodity, and thus risks its value by potentially diluting it and dividing the community among multiple protocols. Each cryptocurrency is scarce, but there is no scarcity to the number of cryptocurrencies that can exist.The Pay-per-Share (PPS) approach offers an instant, guaranteed payout to a miner for his contribution to the probability that the pool finds a block. Miners are paid out from the pool's existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.captcha bitcoin расширение bitcoin bitcoin транзакция bitcoin accelerator and reliability played a key role in the prosperity of the Dutch Republic.
