Title: determin exact time of former difficulty changes
Post by: stoechi on November 05, 2013, 09:45:18 AM
Hi Folks,

i need to know when exactly the difficulty increase of Oct16 happend.

Is there a way to calculate back or are there some graphs that are precise enought to see?

I tried to calculate back, based on the actual average block generation speed, but i figure its not very precise.

Thx!

Blocks have timestamps. Difficulty goes up every 2016 blocks. Using a block explorer, find the block that triggered the difficulty change you're interested in and check its timestamp.

thx, but is there a way to see which block triggered it?

Unless i would have to count back 3957 Blocks by hand in the blockchain.., am i wrong?

Not good anough in perl scripting anymore though :)

Thx
