如何核实在以太姆的矿工的报酬？

Question

在ethash共识的Finalize()函数中，直接通过state.AddBalance()向矿工和叔父提供奖励。

在哪里我可以验证奖励？我想有两个地方

1)VerifyHeader

2)VerifySeal

我不知道这些奖励在哪里被储存在上面。

Answer 1

当节点从规范链导入批块时，它将运行块验证，验证之一是验证状态根。奖励/平衡包括在状态根验证中。

您可以在下面的路径中找到源代码

./go-ethereum/core/block_valdator.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
}
