no winner again lol.  Hey anybody has ideas on difficulty after the fork ?  I mean...depending on BCC price, a bunch of hashrate will cross over...difficulty will be uncertain at the re-adjust, and could cause problems mining blocks, potentially crippling bitcoin if a lot of hashrate leaves ?

Well if a lot leave and 1 fork is 75 percent and the other 25 percent.

It would add Say 5 days to the big fork

And 20 days to the small fork

Did you guys see the analysis of changes to the BCC difficulty rules that will allow large pools to manipulate the difficulty backwards, without waiting for the next adjustment period?

https://www.reddit.com/r/Bitcoin/comments/6q3joc/a_voice_of_reason_in_the_mining_community/

Assuming this is true, is this vulnerability an honest mistake of the devs who perhaps wanted mining to be effective during their first period as miners bail for the main BTC chain? Because if hash power follows BTC, the block rate for the first adjustment period of BCC would approach infinity, given the original rules.

Or was it intentionally designed to be exploitable by large pools like Antpool to maximize their acquisition of BCC block rewards during the initial pump and dump?

This change to the rules might make it interesting to have a thread to guess the difficulty of BCC. Not that I think it's a good idea to legitimize BCC, but wouldn't it be interesting to watch the difficulty go backwards during an adjustment period?

Regardless, the adjustment period for both chains after August 1st will likely be very interesting...

[cakir]

Too bad I couln't get either... I'm gonna guess next time negative. Because of the 1 august shit & BitcoinCash shit.
Some of the miners will point their haspower into BCC...
