Please fix me if I'm wrong. I just investigating the sources of new Electroneum update.
In src\cryptonote_basic\difficulty.cpp there is a function next_difficulty() which calculates the difficulty for new block.
According that function algorithm is the next:
1. take previous DIFFICULTY_WINDOW_V6 = 360 blocks. 2. sort them according to time found (timestamp) 3. throw out first DIFFICULTY_CUT = 60 and DIFFICULTY_CUT = 60 last blocks and keep only 240 blocks. 4. calculate the work (difficulty) done during the time of these blocks and according to that calculate new difficulty.
I see some problem in this algo. 1. Last 8 blocks (307500-307507) are the last current blocks. They will be in the end of sorted list and will be thrown out away! So the next 52 blocks for sure will be last blocks in list too and their time will not be even taken in account during the difficulty calculations. This means the difficulty will start to fall down only on block 307560!
2. To calculate the work done by the last 240 median blocks function next_difficulty() use the target_seconds variable: mul(total_work, target_seconds, low, high); BUT! Variable target_seconds now is set to 120 seconds in function get_difficulty_target() instead of 60 before fork. This doubles the hashrate of the network and the result difficulty for the block 307500 and next!
What thats means? We are now in 3 (!!!) GH/s network and next 52 blocks will not even change the difficulty. The difficulty will go down only after block 307560.
I don't have the answer but it would be good to get some info from dev team on this.....

I believe we should wait and see if the fix is working or not before buying more hashpowers. Hope we will find it out fast.

I don't have the answer but it would be good to get some info from dev team on this..... Here some info related to difficulty from the reddit channel: we neet to find around 600! blocks (10 hrs and less each)
That's a long time. 600! means 600 * 599 * 598* etc. I'd type out the answer to what number that is, but it's 1409 digits long.
adding a ! to the end of a number is the mathematical symbol for factorial, meaning the product of an integer and all the integers below.
it means around 250 days or about 8 months if we have a 10 hour block times. Thats 8 months!
600 blocks X 10 hours = 6000 hours / 24 hours = 250 days / 31days = 8 months
Etn have killed this coin if the above math is correct however we should see difficulty start to reduce in 75ish blocks so only 750 hours if we get 10 hour blocks, or a month
Your source states that the difficulty will begin to drop (for Monero) after 75, reaching full drop by 675. So we would see results by block 75 and the decline begins. Full drop for Electroneum would be less than 675 because the update halved the difficulty window from 720 to 360. This means drop begins 75 and full drop by 435. Please note I am not a blockchain developer and this is a guess at best Somewhere i think i have readed some info, can't find the source anymore, so don't nail me on that one. That it takes either 60 or 120 blocks bevor the difficulty beginns to drop (as said, can't remember exactly what it was, but pretty sure it was either 60 or 120 blocks)

I'am not a blockchain techie and i might totally miss something here, but
if let's say we have at some time 100 rejected blocks and finally a fix comes out, how does that 101st get accepted/validated by rejected blocks?
I mean if the 100 previous blocks are rejected and not accepted by the chain, how would be the 101st accepted?

Can't they change back later after the difficulty goes down? The difficulty algorithm is set in the code and cannot be changed now without another change. I feel sorry for ETN as they did not see this scenario and hence did not implement additional logic to fix/reduce difficulty for x number of blocks.

I hope they can get it fixed in days and not months. Now we know another way ASICs can damage a coin. I hope the Equihash coins take note of this and change their algos asap. Don't let the ASICs mine at all.

actually the equihash coins (expect BTG, eventually Bitcoin Private) decided first to make/order a professional research to see the impact from all angles, not just the miners one, which makes perfect sense for good valued coins that have a given target. You know that you miners are just a small part without real investement of the whole picture of a given project which includes investors, stake holders, companies, traders, foundations, whatever not, And the allready shipped Z9's allready mine since yesterday on equihash, just as a side note.......

Where is this new trade site adding electroneum, I want to see this really developing also on the trading volume so that it can get a good price, I've saved this in 6 months and it has not been profitable for me ![Angry](https://bitcointalk.org/Smileys/default/angry.gif)

No transactions can be made now. You should wait. Maybe with a little chance it will be ok on next week. It will depend on the devs.

If that's the value of your gpu mining hardware it's an investement into YOUR business, not the projects business!

So whatever you say Mr. Newb investor ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) Oh and one other small thing, without miners there is no coin or blockchain or confirmations etc etc etc.... but then again for a big investor like you that means nothing I'm sure...
