I think "Фулл валид" is a Russian term, not quite sure what it means in this context. Sounds like it might be about a cryptocurrency wallet that's fully validated or synced? If you can provide more context or details, would love to help out.
"Full validation is a thing, I've seen it in some of the new PoS coins. It's not unique to ETH, but it's been a sticking point for some investors. Any updates on its potential impact on Ethereum's gas fees?"
