GDPR vs. Blockchain: Technology vs. The Law
My issue with Blockchain and &quot;information laws&quot; (not just GDPR, but any law which prohibits or controls information) is that you (&quot;you&quot; being the creator&#x2F;maintainer of the blockchain) can never mess up.<p>If someone puts &quot;illegal information&quot; directly in your blockchain, you either need a way to roll-back the change (which removes most&#x2F;all of the benefits of an append-only structure like a blockchain), or you need to be okay with breaking the law.<p>That someone could be a blackhat that wanted to publish a bunch of personal info, a disgruntled employee, or just regular users if you allow arbitrary input.<p>I don&#x27;t know of any kind of real solution, and at some point someone is going to push the limits and make it obvious that &quot;illegal information&quot; is on a blockchain, and we (as society) will have to come up with a way to deal with it.
