More accurately, the target adjusts every 2016 blocks. If the period between retargets was less than two weeks, then the difficulty increases. If it was more than two weeks, the difficulty decreases.

That's exactly what I said in my first reply. I was summarizing. Tongue

Thank you. I never thought it was SO FAST. So sad I didn't know about the project last summer...

cdhowie, xenon481, thank you. I think I got it.
I still wonder what's an average speed of hashrate growth for, say, last 6 months. Or last year. Is it possible to find that out?

The idea is to calculate the difficulty for a given time in the future, based on the current trend.

Please excuse a noob, I didn't know it's being ajusted periodically.

No need to excuse anyone; everyone starts a noob.

If it's not clear from the articles, the difficulty is a function of the target; the target adjusts about every two weeks, and this changes the difficulty.

Thanks!

I think I read something about saltatory difficulty adjustment upon reaching some predefined amount of blocks (2 hundred thousand something).
Have to go RTFM.

Greetings!
I'd like to hear from those familiar with the system's statistics. How much time would you say we have until next difficulty level, considering the present hashrate and the hashrate growth speed?

Thanks!

The hash target is adjusted every 2016 blocks to try to cause the next 2016 blocks to take two weeks to find. So, if the network's hash strength is growing, you can expect the target to adjust a bit sooner than two weeks.
