Bitcoin mining share difficulty
Here's a fast way to calculate bitcoin difficulty. It uses a modified Taylor series for the logarithm you can see tutorials on flipcode and wikipedia and relies on logs to transform the difficulty calculation:.
To see the math to go from the normal difficulty calculations which require large big ints bigger than the space in any normal integer to the calculation above, here's some python:. Current difficulty , as output by Bitcoin's getDifficulty. There is no minimum target. The maximum difficulty is roughly: The difficulty is adjusted every blocks based on the time it took to find the previous blocks. At the desired rate of one block each 10 minutes, blocks would take exactly two weeks to find.
If the previous blocks took more than two weeks to find, the difficulty is reduced. If they took less than two weeks, the difficulty is increased. The change in difficulty is in proportion to the amount of time over or under two weeks the previous blocks took to find.
To find a block, the hash must be less than the target. The offset for difficulty 1 is. The expected number of hashes we need to calculate to find a block with difficulty D is therefore. That means the hash rate of the network was. At the time of writing, the difficulty is Retrieved from " https: Pages with syntax highlighting errors Technical Vocabulary.

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.
