My wish: I want to be able to import my really old wallet (my “dogfood” wallet from when I worked at ECC) into my phone so that I can spend the funds in there. I can probably get access to those funds on a PC using zcashd, but so far I’ve been procrastinating doing that, and no mobile wallet I’ve tried has worked; I’ve only ever gotten to like 2% syncing progress.
The spam attack is the reason syncing that wallet takes so long, but even assuming no more spam attacks happen and Zcash usage remains consistent, everyone else is eventually going to have this same problem importing their wallet. Imagine someone creates a new wallet today, uses it for 5 years, then they get a new phone and try to import their wallet into their new phone. They’re going to run into the same issue I’m having now.
