Which file on node contains public and private keys for that individual node?

Question

When a node is connected to multichain, which file contains public and private keys for that individual node allotted by the multichain platform?

Answer 1

Look for the wallet.dat file in the blockchain's sub directory of ~/.multichain/

Comments

How do I extract the public key from wallet.dat? I used the dumpprivkey command for getting the private key but how to get the public key?

If the address is in this node's wallet, you can use the validateaddress call to get the corresponding pubkey.
