About that old tweet of mine that dontbeevil posted to this thread:
For what it is worth, I changed my mind after I posted that (a couple of years ago), because of Gordon Mohr’s arguments that taddresses are a good solution to a legitimate need (for example this Twitter thread), and because of getting more experience with use-cases that require transparency: proof-of-reserves, turnstiles for assaying the monetary base, coin-holder’s petitions, transparent donations to non-profits, etc.
My current belief is that transparency and privacy are both valuable features for different use cases, and the current “taddr-and-zaddr” architecture lets the user choose different tools for different jobs.
