1 that is roughly 7 Mhash/s. Simple example, lets say I give you a range of numbers from 1 to 100. Visit a calculator or perform the maths yourself, Remember it's just probability! If the number is greater than 1 (i.e. . Okay, Ill start with a simple example and go from there. 600 around 157 Ghashes per second. Difficulty is a value used to show how hard is it to find a hash that will be lower than target defined by system. For example if a target packed in a block appears as 0x1b0404cb its hexadecimal version will look as following: 0x0404cb * 2 8 0x1b - 3). Edit The minimum difficulty, when the target is at the maximum allowed value,. Difficulty_1_target can take various values.
Without significant accuracy loss we can simplify it down to: D * 2*32 / 600. Why is the difficulty important? It uses an altered version of Taylor series to logarithm and relies on logs to transform difficulty calculation. Maximum value for this field is 0x7fffff while minimum is 0x008000. If they took less than two weeks, the difficulty is increased. Im a computer, and instead of telling you the target value directly, I find it easier to give you the target by dividing the range of numbers with a new number This new number is able to control the height of the target.
