A little more cumbersome than I imagined but proves that the contents of a tweet can contain a message and a digital signature.

Putting tweets on a blockchain would make it very difficult to delete them or edit them but offer no more certainty than a regular tweet that includes a signature verifiable with a known public key of mine.

I just don’t don’t want someone impersonating me on any one of the many random website I have a profile where anyone with access to the db can write whatever they want under my name.
