Hi @amandatsalis ,

A1: The only reward mechanism Polygon Edge has, which works for both PoA and PoS, is implemented in the executor.go file (from the State folder). The proposer is going to get the coinbase fee. The rewards are stored to the validator's address. The implementation is:

polygon-edge/state/executor.go

Lines 486 to 488 in d3d4f8a

	// pay the coinbase
	coinbaseFee := new(big.Int).Mul(new(big.Int).SetUint64(result.GasUsed), gasPrice)
	txn.AddBalance(t.ctx.Coinbase, coinbaseFee)

A2: You can access the gas fees stored to a certain validator's address via its private key. You can import the account into a wallet, for example, using the private key, and then send the tokens to an address of your choice.

A3: I don't fully understand what you mean by this. Every validator gets a unique public address when you generate the keys.

A4: This flag is not used anymore, we will edit the docs accordingly soon.

how to change this address validator ?

@amandatsalis Can you please provide a bit more context for that screenshot?

[laviniat1996]

@amandatsalis I think that screenshot is from a block explorer. That validator field (or you can call it a miner) is supposed to be the null address, and you can find the explanation for why it is that way here.

[amandatsalis]

Sorry if I often ask, because I'm doing a case study on blockchain, please help.

For example:
in this screenshot their validator is address which is not null. on my localhost blockchain they show null address 0x0000000000000000000000 now I want to change that null address to my address. E.g : 0x348C310221Bba25FEe7D575Bc5D2c90BbCF88191 and get the reward

[laviniat1996]

@amandatsalis The miner field in clique algorithm(used by Edge) has a different meaning. Basically, the miner (validator) field is used to indicate a target address for new signer proposal or delete signer proposal. It doesn't show the proposer of the block, like you see in that example.It will always be the 0 address. Read more about it here .

[amandatsalis]

does that mean I can't change the address validator 0000000000000000000000 to my address like 0x348C310221Bba25FEe7D575Bc5D2c90BbCF88191?

[laviniat1996]

That field doesn't display the actual address of the proposer.

Hi @laviniat1996 I believe what he wants to ask is that, how can we get the block creator's address? You mentioned in #969 that, we can get it from the "extraData" field in the block header. Please guide on how to decode the extraData field. I'd greatly appreciate any help on this.
