I have followed following answer about How to add new Sealer in Geth 1.6 Proof of Authority?.

Currently I have one signer account 0x4e4a0750350796164d8defc442a712b7557bf282. With one signer the mining was working without any problem. My signer account proposed a new signer account using propose() function.

clique.propose("0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd", true) 

On my signer node and other nodes, I can see the new address on my signers list (clique.getSigners()),

["0x4e4a0750350796164d8defc442a712b7557bf282", "0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd"]

Than on my other node which has 0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd I have unlocked that account and run miner.start() command, but no help on mining new blocks on the network. So network stop mining new blocks :(

Also new signer account does not show up on my other connected node, which has the account for new added signer.

Now, I cannot also remove the newly added signer using:

clique.propose("0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd", false)

Please note that both signers are unlocked and miner.start() is active.

[Q] How could I solve this problem?

  • I mean instead of "0x", there is original ethereum address. And another node that address is unlocked and I run miner.start() command but still mining new blocks is stopped. @ivicaa

    Is "0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd" also eth.coinbase? I am not 100% sure, but I remeber having problems when the sealer account is not eth.coinbase.

    Ah I feel like a stupid, eth.coinbase was pointing some other address, when I updated with "0x5b29ede59ecff473fb5760a53dbacc21cbc5b3dd" it get solved. @ivicaa

    I assume it has to be eth.coinbase. I am again not 100% sure, but It might take some blocks until the request is processed. Where I am 100% sure is that both have to vote false for the address which is to be removed.

1 Answer 1


eth.coinbase has to point to the sealing account.

If you want to remove again the second account, both accounts will have to propose the removal. You always need 50% + 1 vote, which is 2 for 2 accounts.
