Need to know how we can use two bitcoin node for example. I do have two bitcoin full nodes A and B. Created wallet address at A and has all transaction details at wallet.db in node A. But I need to keep PK in DB and take those and send request to B node, but it fails as it dont have all transaction details, I dont want to re scan B node every time, is there any way we can achieve this. So that i dont need to worry on which node my request is going.
