, one of the top 30 crypto networks by market capitalization, suffered another in less than a week.
"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."
At the time of writing, no further details about the attack were available.
ETC should just switch to proof of stake. Even given its risk-averse culture, at this point making the jump seems lower-risk than not making it.

As a reminder, a 51% attack happens when a person or a group gain the control of the majority of mining power on a Proof-of-Work (PoW) blockchain network, meaning that they can double-spend and reverse transactions, preventing other users from mining. It doesn't, however, allow the attackers to steal other's coins.
This past Saturday, ETC experienced a 3,693-block chain reorganization that was likely caused by a 51% attack.
Also, ETC suffered a 51% attack .
