npub1snkj7h909uu24mn6qm42j7fclcazek9cfzzgzku8tchz4mj5ymssawyw0p (npub1snk…yw0p) We rolled out the beta version of Key Transparency on our own private blockchain, meaning it’s not run by a decentralized series of validators. The action such as you describe would be detected by the owner of the email address, as they can check their own keys in Key Transparency. In that sense, Key Transparency is a detection mechanism, rather than a prevention mechanism (although it also aims to prevent via deterrence, as malicious behavior would be detected).
