Real Problems That Web3 Solves, Part 1
&gt; We need some way of saying “who we are” on the internet in a consistent manner. That way we can communicate with others in a verified way and associate with digital data that we own. We also often need that data to be interoperable between different web properties.<p>Do we really need this?  Do we really want to permanently tie identity across websites like this? I find this initial &quot;need&quot;&#x2F;justification&#x2F;requirement questionable.<p>I have a login on HN that is totally unique to e.g. Twitter and Instagram and &lt;shudder&gt; LinkedIn. Same with work vs personal. This is deliberate.  I do not want to have the same identity here as I do elsewhere.  There are many hopefully obvious reasons for this - mostly privacy (both in terms of immediate &quot;in the moment&quot; privacy, but also temporal privacy in the sense that I might not want some potentially ill-advised comments I made on some website 15 years ago to come back and bite me), but also it offers protections against &quot;cancel culture&quot; and general cyber-stalking and doxxing etc as that would become a whole lot easier if you can just run some query on a blockchain and find every single website I&#x27;ve ever used and dredge up my comments&#x2F;content&#x2F;etc.  Being able to do that sounds <i>very</i> dystopian to me - why don&#x27;t we just tattoo a barcode on our necks and be done with it?
