Each time you are adding more immutable data to the Blockchain, which cannot be undone. Each of your identities - to which all of your digital content is tied - is permanently associated with that ID.
So if you just have throw-away wallets, how do you use that with your content? You cannot "own" your content if you keep having to abandon wallets to get a fresh advertising ID. And if you keep several different compartmentalized wallets around, as soon as you move something from one to the other or use a different wallet with the same login, you have permanently and irredeemably linked those identities.
Yeah but at that point it’s up to the user. There’s a way to stay anonymous but just like anything relating to privacy, users have to be well informed about their risks and mitigations to be able to manage their data effectively.
I've studied blockchains a little bit but I don't understand how you can transfer funds between two wallets that you own without linking them. How would that be possible without either having some kind of zero sum proof (which none of the popular blockchains are using) or allowing an exploit which enables people to mint new tokens from thin air?
Generating a new public key doesn't add data to the blockchain. Only when you sign a transaction. And if you're talking identities, as in moving around websites, there's no way to link your various public addresses (logins) unless you explicitly do so using the private key you used to generate the public address. Or, you could use the same public address. So, it depends on what you want to do. Do you want privacy? Or, do you want the site to know your activity history?
