In the Ethereum Classic network, the deepest block reorganization occurred during the next attack
The Ethereum Classic cryptocurrency network has undergone another 51% attack. This was announced tonight by Bitfly, the operator of the Etherchain mining pool..
According to her observations, the latest attack was the largest and led to the reorganization of more than 7,000 blocks. “This equates to approximately two days of mining. All lost blocks will be removed from unapproved balances. We will check all payments for missing transactions, ”says Bitfly.
This is the third such attack on the Ethereum Classic network in the last month. The other two occurred on August 1 and 5 and led to the reorganization of 3,692 and 4,244 blocks, respectively.
Earlier, the OKEx exchange announced that it could delist Ethereum Classic if it deems the support of the cryptocurrency unsafe. The Ethereum Classic community, for its part, has presented a list of measures that can be implemented to prevent further attacks..
“We are aware of the current risks to the network at such low hash rates, while ETC is still evaluating the proposed solutions. For miners, exchanges and other service providers in the near future, we recommend raising the requirement for confirmations above 7,000 “, – writes the official Twitter account of Ethereum Classic with reference to Bitfly, without specifying anything on the merits of recent events.
“The ETC hash rate corresponds to ~ 3% of the entire ETH network,” the developers added later. “We are well aware of the potential for re-attacks while solutions such as refactoring constraints continue to be tested and evaluated. If you haven’t already (and most have already), please raise your confirmations above ~ 10K “.
