Ethereum suffered from a technical issue on Friday that caused the network to stop finalizing blocks for over an hour. The chain experienced the same issue Thursday, when finality paused for roughly 25 minutes.
The incident – the cause of which remains a matter of speculation – sparked major security concerns.
"The second wave is over, but I fully expect a third," Superphiz.eth tweeted after today's incident, advising the validators that operate the network to "Increase your hardware spec if you can, switch to a minority client if you can. Apply patches when they're available."
"But really don't worry too much," he added. "As bad as this looks, the chain keeps going and eventually finalizes."
