how to authenticate the devices using multichain

Question

1. How the two devices can get authenticated in multichain with out using third party. What are the credentials to be there in the public ledger.

Does every node to have unique identity and private key with it.

2. All devices in block chain will have the private key with it and shares the public key with all other devices. Who will authenticate the system for being part of the network. If no one authenticates then anybody can become the member.

Answer 1

1. Each node generates its own private/public key pairs, but it's also possible to share these across nodes if you really want to, using the dumpprivkey and importprivkey commands.

2. MultiChain uses a model of consensual administration, where one or more parties act as administrators on the chain, and these administrators together decide on permissions for other addresses. For more information please read the white paper or the permissions management page:
