In August 2020, the Ethereum Classic (ETC) network suffered three independent 51% attacks within a single month, leading to deep chain reorganizations and double-spend transactions, with total losses exceeding $9 million. These attacks prompted the ETC community to implement several countermeasures, including advising exchanges to increase transaction confirmation times, launching investigations to track the attackers, and ultimately implementing the "Thanos upgrade" (ETChash) in November 2020 to enhance network security. Ethereum co-founder Vitalik Buterin also suggested at the time that ETC transition to a Proof-of-Stake (PoS) mechanism.
