Hello, I'm PrincessPersnickety. I wanted to let you know that one or more of your recent contributions have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. Princess Persnickety  (talk)  21:17, 16 August 2021 (UTC)

Hello, I'm Leijurv. I noticed that you added or changed content in an article, Merkle tree, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. as well as advertising/soapbox in all likelihood Leijurv (talk) 22:16, 16 August 2021 (UTC)
