I will show you
There you will see my activities from the last 7 days and that I made this comment and also that I edited it and deleted a word
There you can still see the original post and what I edited, for example that I added the last part later
Just take a look at https://steemworld.org/@dera123
And there are more tools to browse the whole blockchain, but I like steemworld the most because there you can see a lot infos but with the disadvantage that it only shows the activities of the last 7 days.
