Blockchain Privacy: Equal Parts Theory and Theater - Token Daily
https://www.tokendaily.co/blog/blockchain-privacy-equal-parts-theory-and-theater

Bitcoin is Twitter for your bank account. Anyone can see what you’re doing. That includes your family members, friends, current and former romantic partners, business associates, competitors, all the way up to government agencies. Even people who are government decision-makers themselves should remember that other governments — the ones they don’t like — will delve into the details of their finances.

It’s common to say that “privacy is dead,” suggesting that it’s hopeless to protect your privacy. The idea is that someone — the government, Google, a mysterious bogeyman — will always know things about you. But there’s a difference between one person knowing your deepest, darkest secrets, and everyone knowing them. Just because Google knows your browsing history doesn’t mean that you want it to be public.

During the past seven or eight years, we’ve seen many proposals to add privacy to cryptocurrencies. The techniques range from simple things, like avoiding address reuse, to complex cryptographic protocols. Measuring the privacy afforded by a certain implementation is tricky.

Right now, we can’t resort to empirical methods. It would be akin to evaluating internet privacy in 1992, when the only websites were ones at CERN. That was before targeted ads, and tracking cookies; Google AdWords didn’t launch until 2000. Richard Stallman was considered an alarmist crank. It was before we really used the web for anything where it would be worth tracking people.
