What if you recorded a video of yourself, explaining the contents of bitcoin blocks? You could pretend that it’s a little project you’re working on and just ask her for her advice on making it understandable. You could make sure to emphasize the permanence of being on the bitcoin blockchain in the video. About the immense effort miners put into blocks. About how each confirmation makes it more permanent. How Bitcoin will be around for a long time. Etc. how some people have put things they find most meaningful in these messages. At the end of the video you could give her a link to a specific block to look at and test her new skills at finding the messages. Have it be the block your message is in 🥹
