1.)
they all missed the first question: what's your threat model?

"anonymity" has been used to describe a transparent web proxy and a datagram overlay protocol, and everything in between.


2.)
"It is straight forward to move on from secp256k1 to other"

this is actually not trivial! downgrade attacks are a real threat vector, seamless key migration technically challenging, deprecating legacy cipher suites in decentralized systems a significant challenge...


3.)
" The system is locked to work over IPv4 exclusively for one reason. Scarcity. IPv4 i used to control the number of nodes behind an address and thus control sibyl attack. This is the only anonymity-issue I have AFAIK and dont really know how solve with IPv6 or onion."

thoughts:
- exposing IPv4 betrays anonymity (without additional protections)
- IPv4 addresses are a very poor sybil defense.
- IPv6 ORCHID addresses (non-routable virtual addrs) via Tor overlay would be a significant improvement! E.g. https://www.onioncat.org/
- "This is the only anonymity issue" is not reassuring when this issue is a fatal flaw!


Also, "Q: anonymous taxation? lolwut" - hah
