This reduces the ability to cheat the mining pool system by switching pools during a round, to maximise profit. PPLNS method is similar to Proportional , but the miner's reward is calculated on a basis of N last shares, instead of all shares for the last round. Therefore, if the round was short enough all miners get more profit, and vice versa. GM was invented by Meni Rosenfeld.
Multipools switch between different altcoins and constantly calculate which coin is at that moment the most profitable to mine. Two key factors are involved in the algorithm that calculates profitability, the block time and the price on the exchanges. To avoid the need for many different wallets for all possible minable coins, multipools may automatically exchange the mined coin to a coin that is accepted in the mainstream for example bitcoin.
This method also increases demand on the intended coin, which has the side effect of increasing or stabilizing the value of the intended coin. From Wikipedia, the free encyclopedia.

When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every , blocks. Additionally, the miner is awarded the fees paid by users sending transactions.
The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income. Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page.
Early Bitcoin client versions allowed users to use their CPUs to mine. The option was therefore removed from the core Bitcoin client's user interface. See the main article: A variety of popular mining rigs have been documented. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining.
An application-specific integrated circuit, or ASIC , is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially unwise in some countries and setups.
Mining contractors provide mining services with performance specified by contract, often referred to as a "Mining Contract". They may, for example, rent out a specific level of mining capacity for a set price for a specific duration. As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts.
This made mining something of a gamble. To address the variance in their income miners started organizing themselves into pools such as the Bitcoin. See Pooled mining and Comparison of mining pools. Bitcoin's public ledger the 'block chain' was started on January 3rd, at The first block is known as the genesis block. The first transaction recorded in the first block was a single transaction paying the reward of 50 new bitcoins to its creator.
