The Ethereum Classic blockchain suffered a 51% attack Saturday evening, its third 51% attack this month, noticed by mining company Bitfly, which also spotted the first attack on Aug. 1.
- The attack reorganized over 7,000 blocks, or two days' worth of mining, according to a tweet shared by Bitfly. The first two attacks reorganized 3,693 and 4,000 blocks respectively.
- Notably, a leading organization behind the Ethereum Classic network, ETC Labs, announced its strategy to protect the network from additional attacks last week, including defensive mining that is intended to stabilize the network's plummeting hashrate and resist future 51% attacks.
- ETC Cooperative, another prominent foundation supporting the network's development, took to Twitter following Saturday's attack saying, "We are aware of today's attack and are working with others to test and evaluate proposed solutions as quickly as possible."
- After the first two attacks, exchange OKEx responded by saying it will consider delisting the asset due to the network's severe lack of security. COINBASE also took drastic measures by extending deposit and withdrawal confirmation times for ETC to roughly two weeks.
- Following the latest attack, leading cryptocurrency derivatives exchange FTX will reconsider its ETC perpetual futures contracts, according to CEO Sam Bankman-Fried in a private message to CoinDesk. He said this is so even though FTX doesn't support spot trading and the cryptocurrency network's insecurity has less of a direct effect on the risk of offering futures trading.
- The cryptocurrency seems largely unaffected by the series of attacks, trading at $6.86 at last check, less than 4% below its price during the second attack. The coin has traded hands between $6 and $8 for nearly the entire month of August.
- An email to ETC Labs seeking comment wasn't immediately returned.
(UPDATE 23:03 UTC): Adding comment from ETC Cooperative in third bullet point.
