pretty sure bitcoin-armory and other high security wallets have this feature already.
Yes lets push MORE people to abandon full nodes................
We are having a node issue and the idea to helping out is NAH FUCK THAT USE SOMETHING OTHER THAN CORE, It's only for the bare bones.. but becaues of that no one uses it... and we have a node problem.. but we don't want to change it because other wallets have those features so use those wallets.. but use the core because we have a node problem but don't use the core cause it's bare bones..
DO we see the circle here?
Having Bitcoincore does not mean you're running a full node. And we don't have a node problem #. The pseudo problem with nodes and the hashrate is its centralization.
Also i wouldn't run a full node on your active wallet anyways. Best use different wallets for that.
