Hi,

Say difficulty requires 9 leading zeros, then how much more processing(cycles) would be needed if it increase to 10 leading zeros?
How hard does it get?

Thanks a lot!!! =)

5 ½ months  we went from 48 to 62  that is a 29% jump



so 29% in 165 days was slower growth

and 36% in 21 days was pretty fast growth.

difficulty can go  from 440,000,000,000 to 4,440,000,000,000  and then 44,400,000,000,000

and then more.

My guess is we are headed for flatness and slower diff growth  from this april to this sept

I mine alt coins with https://simplemining.net I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Hi,

Say difficulty requires 9 leading zeros, then how much more processing(cycles) would be needed if it increase to 10 leading zeros?
How hard does it get?

Thanks a lot!!! =)

...partial answer to the question...

First off, you are confusing difficulty and target.

Target defines "how many zeros" you need.  Difficulty is defined as the (highest possible target) / (the current target)

Also the target is not just shifting in a one or out a one as you seem to imply.  A target looks like this:

0x00000000000404CB000000000000000000000000000000000000000000000000

Any value less than or equal to the target is an acceptable hash.

The highest possible target with the lowest possible difficulty (the difficulty 1 target) is defined as:

0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

So maybe rephrase your question in terms of target?

Thanks a lot philipma1957 and BurtW!! =D

Is this your question?

For example if the target was:

0x000000000003FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

And it is changed to:

0x000000000001FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

I believe this will double the difficulty and will double the hash rate needed to maintain an average of 6 blocks solved per hour.

Yes, that was my question. I confused difficulty with target.
Thanks again BurtW!! Smiley

I found a nice video that maybe will help others:
