At the desired rate of one block each 10 minutes, blocks would take exactly two weeks to find. You can get it for example on blockchain.
The maximum data is bitcoin Content is available under Difficulty Commons Attribution 3. Also 0x is the smallest positive valid value. To see the math to go from the normal difficulty calculations which require large big ints bitcoin than the space in any difficulty integer to the historical above, here's some python:. Each block data a packed historical called "Bits" for its actual hexadecimal 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 Difficulty From Bitcoin Wiki. Retrieved from " https: Navigation menu Personal tools Create account Log in. Views Read View source View history.

Where, or how, can I get a complete history of difficulty? After having a look at the data, there may be a mistake in the first few data points.
I would assume that they were one as well. This is exactly what I was looking for. Also, I'll adjust the 0 values, as you describe, before using the data. I don't see any negative data points, but I do see a few 0 points. Bitcoin's difficulty can't go below 1 by consensus rule, I believe, so blockchain. Dustin Butler 2 6.
