Here we analyze the [[nonce]] values and [[hash|hashes]] for all the valid blocks in the [[blockchain]]:

==Time Evolution==
===Nonces vs Hashes (y-axis logarithmic, x-axis linear)===
This plot readily shows that the distribution of [[nonce|nonces]] that produce valid [[hash|hashes]] is uniform. 

===Nonces vs Hashes (log-log scale)===
In the animated version of this last plot, you can really visualize the change in the [[difficulty]] and even see where the [[difficulty]] was decreased.

==Histograms==
===Distribution of Nonces===
The nonces found are skewed toward 0 because this is a selection effect: most everyone starts searching for nonces starting at 0, so the lower nonces are found first, even though there may be also higher nonces that could produce a winning block: 

===Distribution of Hashes===
Although the distribution of hashes is not uniform, this does not matter; all that matters is that the distribution of nonces is uniform (which they are, minus the selection effect of starting at 0): 

===2-D Distribution of Nonces & Hashes===
2-D histogram of hashes and nonces (logarithmic color scale): 
 
This also illustrates very well that the distribution of nonces is uniform.
