The Mobile Wallet Tarpit

X Wallet

Privacy depends on uniform transactions
Beware the App Store watering hole attack
Hard forks damage the ecosystem
Privacy-first means money last

The X Wallet falls short of the ideal, but is an improvement over banking and most cryptocurrency apps.

Z Wallet

Stronger privacy against network attacks
Shielded addresses by default
Legal defense against watering hole attack
Hard forks easier to manage
Financed by the Zcash Foundation; privacy first

The Z Wallet would be closer to the ideal cryptocurrency wallet.

One tiny issue...

...you have to write a new Zcash "lite" client

The goal is not software.

Money as email; sending cash in the mail
Make policies transparent, predictable
Stop discrimination in the financial system
Offer equal access to the financial system
Make surveillance of anyone not accused of a crime costly

Mobile wallets are necessary but not sufficient.
