The inscriptions are designed to be easy to use, they even specify that
mime types should be used. I'd say, the way the data is stored is anything
but 'obscure'. UIs will be popping up to make this really easy. The main
chain can't be censored, what's in a block is in a block. I'm predicting a
huge success.

So, are we ready to accept that we'll likely see the first pictures with
insults or worse in the Bitcoin chain? I really like the idea, but the risk
is pretty obvious. I think it would be prudent to have at least an opt-out
feature for the data. So that it's possible to use the chain without the
potentially malicious content. That means the content shouldn't live in the
essential data of the main chain. Better would be something like the
extension blocks in Litecoin.

Best Regards
Claus
