The focus should be: Decentralize security..
For instance, 2 out of 3 signatures required to unlock funds, e.g.
Signature #1 Your home PC
Signature #2 Your Laptop
Signature #3 Your Family/Friend
For instance, transaction must be signed 3 times temporally apart, e.g.
First signing, at time zero
Second signing, at 48h>24h after time zero
Third signing, at 72h>48h after time zero
Then you can freeze your own transactions by double signing.
For instance, to move >X amount within a week, 2/3 signers are required to sign each day for three days.
Since signatures are public information, we can hook this up to email notifying users when movements occur.
