Ethereum co-founder Vitalik Buterin stated that occasional "loss of finality" on the network does not pose serious risks, and confirmation delays of several hours due to vulnerabilities are normal. The key is "not to finalize the wrong block." Previously, a vulnerability in the Prysm client narrowly prevented Ethereum from reaching finality. Oxford University researcher Fabrizio Romano Genovese said that when Ethereum loses finality, its operation becomes more similar to Bitcoin. Such events do not threaten security; they only temporarily shift restructuring guarantees to a probabilistic state. Polygon stated that related incidents might cause transfer delays but will not lead to transaction rollbacks or message failures. (Cointelegraph)
