#加密生态动态追踪 Ethereum co-founder Vitalik Buterin recently shared an interesting perspective on X — occasionally losing final confirmation isn't actually that scary.$ETH

What is his logic? The truly critical issue isn't the disappearance of final confirmation, but rather the system confirming an incorrect block as final. This seemingly subtle difference actually concerns the core of security.

Blockchain research partner Fabrizio Romano Genovese strongly agrees. He further pointed out that when final confirmation is lost, $ETH actually becomes more similar to the operational logic of $BTC — Bitcoin has had no formal final confirmation mechanism since its inception in 2009, but who dares say it's unsafe?

Genovese explained clearly: such events do not weaken the security guarantees of the blockchain itself. Rather, the assurances around block reorganization shift from certainty to probability — in other words, you need more mathematics and time to verify, rather than an absolute final verdict.

In practical terms, Polygon pointed out a real issue to the industry: when transferring from $ETH to sidechains, if you have to wait for final confirmation before cross-chain transfer, the delay will increase accordingly. This means that in extreme cases, user experience could be affected.
