Etherum Classic and another 51% attack

The Ethereum Classic (ETC) network was hit by another 51% attack on August 29, causing over 7,000 blocks to be reorganized, one mining company Bitfly noted. The attack came weeks after developers proposed changes to the network in the next three to six months. The immediate actions they have taken include defensive cooperation with mining pools to maintain consistent and even increased hashrate, advanced network monitoring, whitelisted addresses, and a final arbitration system to stop chain reorganization.
