On Saturday morning, there was an attempt to reorg the ABC chain a third time, but it was reverted by the pool Mining Dutch.

On Friday, in a reply to Buterin’s tweet about the mystery miner, BCH proponent, and researcher, Javier González explained that the mining pool’s technique was not an attack.
