This is the one thing I hoped for out of crypto/blockchain.
You, commenter, don’t need to know that I’m “Brian Brianson, a citizen living at 123 Abenue Avenue”. But, it’s good to know that the person commenting is a real person who has been seen and verified by someone, as a simple true/false flag. If there were good ways of verifying basic conditions of people you interact with online, without exposing personal details, then it could curb botnet opinionation as well as be useful for a lot of things.
I’m imagining something like being able to go to a lawyer, or journalist’s office - somewhere they’d have established notaries, and show them a driver’s license or other notable documentation. They wouldn’t be granted rights to record that information permanently, but would grant a cryptographic signature sourced from their office to express that their office has seen them.
This would rely on professional trust - that the people you show your info to will not record it; and, that if they for some reason have to, they won’t turn it over to warrants. By the same token, they’d be trusted that they’re not inventing people from thin air.
You’re right that someone engaging online long enough could be exposed. That would then rely on any effective “Right to be forgotten” laws to erase unnecessary data.
