By following this tutorial. I have created a private chain based on Proof-of-Authority. Please see my CustomGenesis.json file.

I have started my chain:

> geth --datadir /Users/ethereum/POA/private --unlock 0xd531eab21f883abe0f79103188bfc6468712f409 --mine --rpcaddr --rpcapi eth,net,web3,personal console

INFO [01-16|15:53:58] Unlocked account                         address=0xD531EAb21f883aBe0F79103188bfc6468712f409
INFO [01-16|15:53:58] Transaction pool price threshold updated price=18000000000
INFO [01-16|15:53:58] Starting mining operation
INFO [01-16|15:53:58] Commit new mining work                   number=22 txs=0 uncles=0 elapsed=116.62µs
INFO [01-16|15:53:58] Successfully sealed new block            

I observe that: Balance of my each account remains unchanged if there is no transaction on the block. If there is a transaction, authorities' balances, slightly increase (I couldn't figure out with what percent each account gain a reward).

Also at each mined block,miner address returns: 0x0000000000000000000000000000000000000000


[Q] How does reward mechanism works on Proof-of-Authority consensus? Is there any gas price? Who gains the used GAS via transaction with what percent as a reward on the each block?

Thank you for your valuable time and help.

  • Do you mean Proof of Authority, not Proof of Stake? (That tutorial is for PoA.) – Richard Horrocks Jan 16 '18 at 17:26
  • Isn’t Proof of Stake and Proof of Authority same? Is there any difference between them? @Richard Horrocks – alper Jan 16 '18 at 17:45

    Hi @Alper. There's a difference. PoA uses centralised, authority nodes to mint/approve new blocks being added to the chain. PoS, depending on how it's implemented, is more decentralised, and allows anyone to participate in the validation of blocks via a voting mechanism. – Richard Horrocks Jan 17 '18 at 18:38
  • Doesn't on POA authorized users, which allow to seal votes, will allow new users to be authorized also under clique()? @Richard Horrocks – alper Jan 18 '18 at 7:29
