Identify address nodes

Question

Hello  multichain,

I have created two nodes lets say N1 and N2.  the chain has been created on N1  and N2 is connecting to N1.

I have created three addresses on N1 and two addresses on N2.  If I do getaddresses on N1 I get those three addresses and same on N2 I get two addresses. But in  application given a address is it possible to identify which node the address belongs to?

Answer 1

No, this capability is not built into a blockchain, since it is possible to share addresses between nodes, and for nodes to generate addresses without publicizing and information about this on the blockchain.

You could however use a stream in which any node can publish an item with its node number. Then looking up the node for any address would be an easy matter of using liststreampublisheritems.
