Hello, although i am in the crypto for 2year+-, i am not so sure about what block difficulty is

Hope i get it right, so block difficulty can be explain as
It start off 2 ppl carry 2 stone which is 2kg, it takes 10minute

Then, after some time, 3 ppl carry 2 stone which is 2kg, it takes around 6.x minute

So 2 weeks later, the amount of stones will become 3 in order to suit the 3 person who carry so the time will be back to 10minute?

Did i get it right?

Therefore, if lets say suddenly, 1 people broke his leg, which means it will now be 2 person carry 3 stone, so time taken to solve will be long?

Thanks

You got it right :)
that's actually a pretty good way of explaining difficulty to new members, i might have to point them towards this thread the next time i'm about to explain how difficulty works.

The only slight "mistake" is the fact that you cannot use the term "2 weeks later"... The difficulty doesn't adjust every 2 weeks, it adjusts every 2016 blocks. So in your story, the number of stones gets adjusted every 2016th trip the people make. If there are 2 people that carry 2 stones, it takes them ~10 minutes/trip (sometimes longer, sometimes faster, but the average trip time is ~10 minutes), so 2016 trips are ~2weeks.

If one breaks his leg, and the other person has to carry the two stones (time between blocks ~20minutes), it *might* take 4 weeks before the difficulty gets adjusted to one stone (depending if the other one breaks his legs at the very beginning of the period, or near the end of the 2016 trip period)
