Address availability when node is inactive.

Question

Considering 4 nodes in a network connected to chain0 and each node have 2 addresses (one for node and another for entity associated with node). If node 1 is down then is it possible to send assets from entity associated with node 1 to other entities in other nodes.

Answer 1

In a blockchain assets are locked under their appropriate private keys, so one node cannot spend another node's assets unless you have deliberately shared private keys. You can do this if you wish using dumpprivkey and importprivkey but be aware that it removes the fundamental security premise of the blockchain, which is decentralized control.
