Hey #Nostr the #Nymchat app now shows a build integrity from the about modal. This is to verify the app being used was truly built using the files shown in its git repo. Additionally, there is a warrant canary, which is cryptographically signed using my Nostr key and adds a freshness anchor using the latest Bitcoin block height and hash at signing time. Because that hash could not have been known before the block existed, it proves the canary was signed after a specific point in time and was not pre-signed in bulk. Can't get any more cypherpunk than this. https://file.nostrmedia.com/p/d49a9023a21dba1b3c8306ca369bf3243d8b44b8f0b6d1196607f7b0990fa8df/a82c3250037cc632798a17daec025617feef0c42a32a440cb2ec4339d6c44ab8.png
