Hi all, I'd like to hear your thoughts on Bitcoin privacy.
tl;dr: I tend to think we should have privacy for small transactions but retain public pseudonymity for large (significantly society-impacting) transactions so that the wealthiest individuals, large corporations, and governments can't hide their activity. I worry that we're building privacy tools for ourselves now (a legitimate cause) that could be used nefariously by the most powerful later on. What do you think?
Long-winded version: Right now, we have pseudonymity (names aren't inherently attached to transactions but public addresses are), but since most ways of buying bitcoin require KYC identity verification, names are being linked to addresses. It seems like the more Bitcoin is adopted, the more people's entire financial activities will be public, which is far from ideal. Various initiatives are underway to bring better privacy to Bitcoin, but herein lies my concern.
I'm not convinced total transaction privacy is good for the world either, as some Bitcoin privacy advocates appear to be. We live in a world where individuals can possess as much wealth as small nations, and they deploy that wealth to influence the world in their favor. We all do this to the extent we're able, so I'm not arguing against that per se, but I think it's crucial to healthy society that this influence is public, not behind closed doors, under the table, or via 'dark money' (sadly the current system). I don't think it needs to be inherently connected to names, but the transactions themselves should be public so we can have good data about what's happening in the world (think Glassnode but on a global economic report scale) and form good policy based on this data (regardless of how large or small you think governments/community organization should be).
I'm not technically knowledgeable so forgive any misstatements, but my understanding is things like Lightning are bringing more/better privacy to Bitcoin, which I think is great. People should be able to shield their financial activity from others, especially dictators, up to a certain amount. But if Lightning grows to a point where billions of dollars can flow through it fairly opaquely, what's to stop, say, these dictators from using it to operate with even less accountability than at present? I know that the 'criminals use bitcoin' narrative is ridiculous at present, but will it always be ridiculous if massive, untraceable transactions become possible?
We're building legitimate privacy tools now with ourselves in mind, but if Bitcoin becomes as big as we think it will, are we actually building privacy tools for the very elite/governments we're trying to achieve financial freedom from?
I guess what I'm trying to say is that I think the original Bitcoin design (public pseudonymity) is genius but since that's been somewhat compromised by KYC, the backlash is trying to make Bitcoin transactions private, and I worry that both full KYC and full privacy are bad for the world.
I'd love to find out this isn't an issue, either for social or technological reasons, so let me know your thoughts!
