Bitcoin Cash hard fork activates, splitting the chain in two

As of the time of this writing, the Bitcoin Cash blockchain has split between two implementations: Bitcoin ABC and Bitcoin SV., which is in favor of Bitcoin ABC, has mined block 556767 on the Bitcoin ABC chain. Mempool, which is in favor of Bitcoin SV, has mined block 556767 on the Bitcoin SV Chain, according to data from Coin.Dance.

14 blocks have been mined under the new consensus rules, with the Bitcoin ABC chain ahead of the Bitcoin SV chain by one block. It is currently too early to tell which chain will be the dominant Bitcoin Cash chain. Major exchanges have halted trading for bitcoin cash until the chain split is resolved.
