How would this affect the user in terms of disk storage? T= hey're going to get hammered on space constraints aren't they? If i= t's not required how likely are users to enable this?

Hello,

This is primarily aimed at de= velopers of SPV wallets.

The recently reported decrease in num= ber of full nodes could have several reasons, one of them that less people = are running Bitcoin Core for the wallet because the other wallets are getti= ng ahead in both features and useability.

It's great to see innovation in wallets, but it's worrying that= the number of full nodes decreases.

It may be that lots of people = would support the network by running a full node, but don't want to go = through the trouble of installing bitcoin core separately (and get confused= because it's a wallet, too).

Hence I'd like to explore the idea of adding an op= tion to popular SPV wallets, to spin a bitcoind process in the background. = This could be pretty much transparent to the user - it would sync in the ba= ckground, the wallet could show statistics about the node, but is not depen= dent on it.

In exchange the user would get increased (full node level) security, as= the SPV wallet would have a local trusted node.

Does thi= s sound like a good idea?

Is there any way that Bit= coin Core can help to accomedate this 'embedded' usage? Specific In= terfaces, special builds - maybe add a walletless bitcoind build to gitian = - bindings, dlls, etc?
