I guess encryption of this may be nice.

* it stores public keys
|
|
* it stores transactions applicable to the keys it owns.
|
|
store by block-height and offset-in-block
|
|
* it stores the last block it saw (block-id)
|
|
* I should also be able to fund a Transaction Creator, which selects from
|
|
funds and then signs.
|
|
|
|
when starting I connect it and it starts by checking which blocks it has not
|
|
seen yet and download those and find any transactions in them.
|
|
|
|
I need some way to get a list of unspend outputs
