Bitcoin Cash hard fork BCHA faces 51% attack
The recently forked BCHA chain is currently under attack by an anonymous miner that is attempting to force whatever is left of the chain into non-existence.
The anonymous miner, known as voluntarism.dev has changed the Coinbase rule so that all miners need to send 100% (instead of 8%) of the block rewards to the IFP address.
This is a soft fork and these blocks are considered valid by other miners since the ABC rule is that at least 8% needs to be donated but voluntarism.dev will orphan any block by miners running pure ABC (not sending 100%).
The notion seems to be that the ‘miner tax’ imposed here is unfair, and if BCHA wants to take 8% of the reward from the miners, why not just take it all entirely? Miners would essentially be forced into going bankrupt or to stop mining BCHA.
