Perfect privacy without extraordinary computational overhead today means dow=
nloading everything. But we could provide better tools to *shift* bandwidth r=
equirements rather than try to reduce them.=20

I've been thinking about a setup where user runs a UTXO only, and maybe even=
 outbound-connect only (like bitcoinj), full node at home. Then using Tor, m=
ostly for tunneling, they host a hidden service they can connect back to fro=
m their smartphone to see balances, manage receive addresses, send funds, et=
c.

The smartphone is not doing SPV, it's like a web client for the wallet runni=
ng at home. The initial connection between the smartphone and home wallet ha=
s the phone learn two codes, one is the hidden service name, another is an a=
ccess token which is revocable. You may require further authentication from t=
hat point.=20

With fast bootstrapping / checkpointing of the UTXO I think usability could b=
e as good as SPV, and you would get push-notification of relevant transactio=
ns with zero privacy trade-off.

I wonder if people would want to run such an app, if they would run it on th=
eir desktop, a dedicated machine, or an old smartphone or other cheap ARM de=
vice.=
