Anonymity - monero, zerocash, zcash and more

[regexlove]

Let's  collaborate a comparison of increased Anonymity blockchains  - or just start by putting together relevant links to specific posts,
refering to [future] scenario(/s) such as:
-  Most of adresses representing verified identities,  who entered the blockchain through an exchange 
   (Possibly avoided through more decentral exchanges )
- A majority of adresses sharing the "viewkeys" (as in monero) with either the public or for verification.
- Most exchanges exchanging their data for creditworthness-calculation, law-enforcement, and so on.
- Goverments or other entities tracking/recording all IPs involved in the Network from the beginning
- Goverments or other entities attempting to solve / conclude further pieces of the puzzle no matter how huge/obfocusated it may be
- Goverments or other entities running [too] many Blockchain nodes
- Goverments or other entities running [too] many TOR nodes
