I am trying to make private block chain. I am following this link
If it is importing all the headers that means its syncing with public block chain.
So to make private blockchain. Please follow below steps
- create genesis.json
- run on mac terminal - "geth init path_to_geneis/genesis.json"
- then to start your private network run - "geth -networkid=111 console" [111: choose any unique number for network id]
- your console for private network will get open. now you can proceed !!
Thanks in advance.
