When is a clique.proposal known to other nodes?

Question

I do not really understand how a proposal is communicated to the other nodes.

I have 5 nodes in a PoA private ethereum network. I am trying to add 2 nodes on another server. I get this -

instance: Geth/v1.8.2-stable-b8b9f7f4/linux-amd64/go1.9.4
coinbase: 0x242f75170b0b38917995724bd5aef1aa07d31fff

 datadir: /home/satoshimaca/blockchain3/node1
 modules: admin:1.0 clique:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0

> clique.proposals()
TypeError: 'proposals' is not a function
    at :1:1

> clique.proposals
{
  0xf39995b718ae7a0075557f9781425b92fd8b28a6: true
}

but when I attach geth to node 2 I get this -

Welcome to the Geth JavaScript console!

> clique.proposals
{}

When will my proposal be known to node2 or should I manually add to all the nodes?

Also I do not see any reference in my log to the proposal.

Answer 1

clique.proposals returns the proposals submitted by the node on which you run the command. Once a proposal has been submitted by the critical mass (IIRC 50% + 1 of the current authority nodes), it is accepted and the given address is added to (true) or removed from (false) the list of authority nodes (signers).

You can check the current list of authority accounts with clique.getSigners().
