On or before November 1st, Bitcoin ABC will publish a new software version that contains an updated Difficulty Adjustment Algorithm (DAA).
This is a change to the Bitcoin Cash consensus rules, but the change does not activate until November 13th. This is a hard fork, so exchanges, wallets, and other software need to upgrade before November 13th.
We have been in communication with Bitcoin Cash miners and they are expecting this upgrade.
The original Bitcoin Cash “EDA” allowed Bitcoin Cash to survive as a minority chain but produces wild fluctuations of hashrate. This is problematic because it prevents consistently fast confirmations for users, and radically shifts the coin issuance schedule.
