Atlantis Hard Fork for Ethereum Classic Scheduled for September 17 Launch

The Atlantis hard fork for Ethereum Classic (ETC) has been officially set to occur at block 8,772,000 on the blockchain, according to the Ethereum Classic Improvement Protocol (ECIP) finalization call via Discord on June 20.
As per the discussions in the call, the developers and contributors had previously considered putting the hard fork at block number 8.75 million, which is predicted to run on September 15.
However, since the 15th is a Sunday, ETC Labs moved to increase the block number in order to have the projected update during the week, when more involved parties, such as exchanges and developers, are more likely be present to discover and deal with any issues that may arise.
