  • Thank you for writing the explanation! I still think that this doesn’t need a blockchain. Instances could broadcast user creation, so each instance could validate user age on its own (or ask other trusted instances when they first “saw” that user).

    Fundamentally, blockchain solves the problem that there is no central source of trust, but in the Fediverse people necesarily trust the instance that they sign up, so a blockchain can’t add much in my opinion.


  • I see. I’m not convinced that proving the account creation date makes much of a difference here. Obviously the instance records when you sign up, so you would only need this to protect against malicious instances. But if a spammer is manipulating their instance to allow them to spam more, you have a much bigger problem than reliably knowing their account creation date.
