Fun thing to do:
- Go to a presentation about blockchains solutions.
- Ask how they plan to become GDPR compliant, specifically the part about right to be forgotten.
Girl I know did this at two separate conferences, the answer is that they can't, and it makes their presentations/products a bit ridiculous, especially in europe.
We once had a meeting at work how we could use blockchain in our products. With us being the only authority to use that blockchain and having it be confidential so nobody else can look at it. Oh and of course it should be possible to alter transactions later on.
Was a pretty funny meeting.
