geth 如何驗證乙太坊礦工的獎勵？

在 ethash 共識的 Finalize() 函式中，礦工和叔叔的獎勵是直接由 state.AddBalance() 給出的。

我可以在哪裡驗證獎勵？估計有兩個地方

1)驗證標頭

2）驗證密封

我不確定獎勵儲存在上述其中之一的位置。

當節點從規範鏈導入一批塊時，它將執行塊驗證，其中一個驗證是驗證狀態根。獎勵/餘額包含在狀態根驗證中。

您可以在以下路徑中找到原始碼

…/go-ethereum/core/block_validator.go

func (v *BlockValidator) ValidateState(block, parent *types.Block, statedb *state.StateDB, receipts types.Receipts, usedGas uint64) error {
   header := block.Header()
   if block.GasUsed() != usedGas {
       return fmt.Errorf("invalid gas used (remote: %d local: %d)", block.GasUsed(), usedGas)
   }
   // Validate the received block's bloom with the one derived from the generated receipts.
   // For valid blocks this should always validate to true.
   rbloom := types.CreateBloom(receipts)
   if rbloom != header.Bloom {
       return fmt.Errorf("invalid bloom (remote: %x  local: %x)", header.Bloom, rbloom)
   }
   // Tre receipt Trie's root (R = (Tr [[H1, R1], ... [Hn, R1]]))
   receiptSha := types.DeriveSha(receipts)
   if receiptSha != header.ReceiptHash {
       return fmt.Errorf("invalid receipt root hash (remote: %x local: %x)", header.ReceiptHash, receiptSha)
   }
   // Validate the state root against the received state root and throw
   // an error if they don't match.
   if root := statedb.IntermediateRoot(v.config.IsEIP158(header.Number)); header.Root != root {
       return fmt.Errorf("invalid merkle root (remote: %x local: %x)", header.Root, root)
   }
   return nil
}
