In a Core Devs meeting on Friday, Ethereum (ETH) developers discussed potential measures that could be taken to prevent successful 51% attacks from occurring.
The discussion was inspired by this week’s 51% attacks on Ethereum Classic (ETC) — a network that represents the original state of Ethereum where the consequences of the DAO hack in 2016 were not reverted. The original attack, which occurred between July 31 and Aug. 1, was revealed to be a carefully orchestrated attempt at a double-spend that netted over $5 million in ETC to the attacker for a $200,000 investment in hashpower.
