Ethereum Classic (ETC), one of the top 30 crypto networks by market capitalization, suffered another 51% attack in less than a week. (Updated at 06:50 UTC: updates in bold.)
“Today another large 51% attack occurred on the #ETC which caused a reorganization of over 4000 blocks. Until further notice ETC pool payouts are disabled and we encourage all our miners to switch to our #ETH pool at http://ethermine.org in the meantime,” Austria-based blockchain company Bitfly said today.
Additionally, ETC Cooperative, a team of ETC developers, urged all “exchanges, mining pools and service providers either significantly increase confirmation requirements or temporarily pause any deposits or payouts.”
Another ETC team, ETC Core, called “all honest miners and pools” to “sync together to defeat this malicious actor on our network.”
