Hi !

I want to use private keys (wallet.dat) on machine A, and blockchain data on remote machine B - how can I do this ?

Install Bitcoin Core on remote machine B and call it through JSON-RPC. Assuming machine A is local to you accessing private keys should not be an issue.

Put the wallet.dat on a network share. Then make a symlink to it from the data directory.

Export private Key and use it with https://coinb.in/ on any maschine,

I trust myself only For example, blockchain.info is lagging periodically every 2-3 months, when I having my own blockchain on VPS is up and running.

Those approaches works only if we assumes, that we use one-to-one - wallet.dat to blockchain, what if I want one blockchain and many wallet.dat's ?

Means, I want use Bitcoin Core in the "light wallet's way" - like Electrum, so I have many wallet.dat's and one blockchain.

That is, to my knowledge, impossible. The way Bitcoin Core is designed makes it impossible for several instances of the client accessing the blockchain at the same time.

You can always either combine the wallet.dat together by dumping the private keys and importing them or switch them out when needed.

Could you do that with a wallet on a mobile, and the blockchain on a PC?

Theoretically yes, but don't be surprised when your wallet crashes pretty often! Everytime you lose the connection or there are delays or whatever problem occurs, baam the client will propably crash!

That's not how it works. Your client will not crash, but will give a couple of errors when it is unable to view transactions.

My bigger concern is how you will be able to connect like that. An iOS device defenitely will not be able to do it, and an android maybe with some mods, and there's a chance windows phones would be able to do this (But who uses windows phones anyways...). Why not just use Mycelium, and host a node on your PC? (To my knowledge, mycelium cannot connect to a custom specific node, but hosting a node will contribute to the pool of legitimate nodes for us all!)

I was thinking of using bluetooth or usb to connect to the blockchain. I'd probably remove the sim from the phone as well.

On thinking about it, I guess it wouldn't work. If I updated the blockchain on the pc, then I guess the mobile would have problems re-sync'ing itself.
