Transact on another node

Question

Hi,

Can I make a transaction on a different node from which the transacting address exists? For instance, two nodes A and B each with addresses having some assets. Can i transfer an address's assets from node B if the address was generated in node A.

I know the answer is No and one reason why is because the private key for the addresses are stored on their node. I am looking for additional reasons if there is as well as how to go around this for instance if I have the address, public key and private key copied to a file, and the node goes down, can i transfer the assets owned by that address from a different node?

Thanks.

If you have a copy of the private key of another node, you can do anything on that node's behalf. There are two main ways to do this:

1. Import the corresponding address using importaddress, then use createrawsendfrom to build transactions and separately sign them using the externally held private key. See this tutorial for more information: http://www.multichain.com/developers/external-key-management/
2. Import the private key fully using importprivkey, in which case the node behaves exactly the same as if it was its own address to start with.
