Multichain Node and address private key.

Question

in this thread, https://www.multichain.com/qa/6559/multichain-cluster-stops-mining?show=6559#q6559, there is a statement stated that "if you are assigning mining permissions to new addresses, but the private keys for those new addresses aren't owned by any active online nodes" 

Does this mean each node support their own private key its correspond address ? Suppose that this condition is in the same blockchain.

 

Answer 1

I'm not sure if I understood the question correctly, but yes, each node can store its own private keys, for the corresponding addresses. You also have the option of storing keys outside of the node:

However this is not an option for the addresses with mining permission, because the node needs to be able to automatically sign the blocks it creates without depending on an external system.

I mean if node1 has issued addresses, and node2 has issued some addresses, so if addresses in node1 can transfer asset to address in node2 ?

Yes, of course, any address on the blockchain can transfer assets to any other.

---

another question, if a node down/fails will the addresses that were issue in that node can use any more ?

That depends on whether you back up the private keys...

Answer 2

Ok so your wondering about private and public key pairs..

every block has private and public keys.  Each wallet has 2 keys as well.

You do not lose those keys, because they are considered your only security deposit. like your finger print in Biometric Security. Like I'm creating into this multichain.  You have your hand thats the public, and your signature is your private key.
Think about it that way :-)

I hope that information helps.
