On November 15, the Bitcoin Cash (BCH) network was upgraded and the first block was mined under the new consensus rules. Out of the two networks, the Bitcoin Cash Node (BCHN) obtained the majority of hash power, while Bitcoin ABC (BCHA) received very little hash power, indicating that miners generally favor BCHN over BCHA. Bitcoin ABC, the historically dominant implementation of Bitcoin Cash, appears on the brink of losing to challenger Bitcoin Cash Node (BCHN). Before the fork, 80% of miners were already signaling support for BCHN. Roger Ver, executive chairman of Bitcoin.com and the biggest advocate of Bitcoin Cash, is not a fan of the scheduled upgrades on the network, which take place every six months. "If PayPal knew that this sort of contentious hard fork was likely to happen, maybe they wouldn’t have added Bitcoin Cash at all to their roadmap," Ver told CoinDesk, "so it's really a big problem to have these contentious hard forks." Most major crypto exchanges are expected to support the Bitcoin Cash Node (BCHN) and it will therefore inherit the coveted "BCH" ticker after it steamrolled Bitcoin ABC in the most recent hash war. The failed Bitcoin ABC proposal was led by Amaury Sechet and a group of developers who wanted to include in the upgrade a new and controversial "Coinbase Rule," which would have required 8% of mined bitcoin cash to be redistributed to Bitcoin ABC to finance protocol development. The last Bitcoin Cash common block was at block height 661,647 and was mined by Binance, and the first BCHN block was mined by AntPool.
