Where are the node key pair is stored ?

Question

I have been testing new version of multichain, and I wonder where is the node keypair is stored, and how about the new address keypair ?

Every time I try to generate new address, is it belong to node keypair, if so how can we generate separated key pair for specific address we wanted too in Multichain ?

Answer 1

MultiChain stores its key pairs inside the node's wallet file, called wallet.dat

Each node wallet can store multiple key pairs / address, and there's no single address that has any special status from the perspective of the wallet.

can we generate wallet address in multichain: an address that have it own key pair and can generate new address using it own privateKey ?

Yes, of course, this is what the getnewaddress API does.

But I don’t see any private key response. And also when we are doing tx there is no need to input key in order to sign .

After calling getnewaddress you can obtain the private key for it using dumpprivkey.

For high-level transaction APIs the node automatically signs with the necessary private key before broadcasting. If you prefer you can use createrawsendfrom to pre-build a transaction and then sign and send it in separate steps via signrawtransaction and sendrawtransaction.
