Vitalik Buterin introduced a new fast confirmation rule for Ethereum, allowing users to obtain a non-revert guarantee for transactions after just one slot (12 seconds). He noted that its security relies on two assumptions: most validators are honest, and network latency is below ~3 seconds. While its security is slightly weaker than economic finality, it remains highly reliable for many use cases. https://t.co/CTyvqQ4LfC ...
