I have created the genesis.json The genesis json content is

  "config": {
    "chainId": 46860,
    "homesteadBlock": 1,
    "eip150Block": 2,
    "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "eip155Block": 3,
    "eip158Block": 3,
    "byzantiumBlock": 4,
    "constantinopleBlock": 5,
    "clique": {

and have run geth --datadir node1/ init genesis.json to initialise with the genesis block. Then after creating and making the boot node up, I am trying to make my node up using

`nohup geth --datadir node1/ --syncmode 'full' --port 30303 --rpc --rpcaddr --rpcport 3503 --rpcapi 'personal,db,eth,net,web3,txpool,miner' --bootnodes'enode://00f1bd4f26b16a7216a46de5324aac8b33ec3fbc3de4987c06dfa7549511210b9745961e2664b46cc63eafbfff37fd0b135080766ba5efde28c33131e0c13c9
8@' --networkid 1505 --gasprice '1' --unlock 0 --password node1/password.txt --mine > node1/01.log 2>&1 &`

where "00f1bd4f26b16a7216a46de5324aac8b33ec3fbc3de4987c06dfa7549511210b9745961e2664b46cc63eafbfff37fd0b135080766ba5efde28c33131e0c13c9 8" is my boot node address.

I am using go-ethereum v1.9.1-stable-b7b2f60f.

The error logs of making the node up is enter image description here

I have checked with older version of geth v1.8.27 the problem cannot be reproducible, so is it the version issue?


Clique needs the initial list of signers in the extra-data section. Please use puppeth to generate a valid Clique genesis block. You don't need to manage your network with Puppeth afterwards, you can also just create the genesis and dump it out.

  • It is always advisable to use puppeth to generate genesis.json file if one is using PoA for creating the private blockchain – Kshitij Rastogi Aug 9 '19 at 8:54
