I’m becoming more and more concerned about my privacy, especially after moving to Germany and starting using web3 social networks

In Germany, it still feels strange to see my full name displayed on my apartment door. It might not be a problem if I had a German name, but I don't. Because of this, I'm trying to not post photos around my area - anyone could easily find my building just by checking the doorbells.

Also, nearly every service here in Germany - like massage, or hairdressers - asks for personal info such as address and phone. And given how these services are made and how often data leaks happen, I give incorrect data everywhere.

And with Farcaster, I’m now sharing some financial activity tied to my identity. It’s made me much more careful about which wallets I expose to avoid revealing sensitive transactions like travel payments - something I hadn’t really think a lot before Farcaster.

This feels like an underdiscussed “existential” risk of onchain social/perhaps public blockchains in general. The more data and history tied to your onchain identity, the more valuable it is for composability - but also the more public it is, which people just are not used to wrt their finances and also has its own downsides ofc.

Obviously the solve is like, don’t do materially stuff on public wallets. But nobody uses that qualifier when talking about how great “onchain” is

it's also really easy to make mistakes with this that you can't take back

Right but to your point, onchain apps also reward us in all kinds of ways for doing the maximum number of things on our main public wallets, so the trade-off is real.
