So on the other hand, Node: Bitcoin ABC (Bitcoin Cash; Bcash) is stuck on Current height: 478558 from a couple of minutes after the block was mined. And there's been no blocks since.
It's going to take them 2000 blocks to get their mining difficulty adjusted? And while that's waiting, any transactions are stuck?
everything in bitcoin cash has been based on time instead of block numbers or number of blocks.
the fork was on a fixed time (12:20 UTC) if i am not mistaken which is block #478558 i don't know if stuck is the right word but since the hash rate is low for BCC and the difficulty is high it takes a long time to find a block so the blockchain is staying there and BCC nodes are rejecting the new blocks mined on bitcoin chain.
also their difficulty adjustment is based on time. it is after a fixed amount of time passed that they readjust the difficulty and lower it. i think it is after 6 hours with 0 blocks.
and that first block MUST be over 1 MB or else it will be rejected so the BCC mempool MUST have a lot of transactions already to fill a > 1 MB block.
and all this time all those transactions on BCC chain will remain in the mempool as unconfirmed and stuck or waiting.
