1.矿工区块奖励计算方法

打包者：blockReward + blockReward/32 * uncles.length

Uncle： ((uncle.Number + 8) - header.Number) * blockReward /8

go-ethereum/consensus/ethash/consensus.go

// AccumulateRewards credits the coinbase of the given block with the mining
// reward. The total reward consists of the static block reward and rewards for
// included uncles. The coinbase of each uncle block is also rewarded.
func accumulateRewards(config *params.ChainConfig, state *state.StateDB, header *types.Header, uncles []*types.Header) {
    // Select the correct block reward based on chain progression
    blockReward := FrontierBlockReward  //5ETH
    if config.IsByzantium(header.Number) { //区块高度 > 4370000
        blockReward = ByzantiumBlockReward   //3ETH
    }
    // Accumulate the rewards for the miner and any included uncles
    reward := new(big.Int).Set(blockReward)
    r := new(big.Int)
    for _, uncle := range uncles {
        r.Add(uncle.Number, big8)
        r.Sub(r, header.Number)
        r.Mul(r, blockReward)
        r.Div(r, big8)
        state.AddBalance(uncle.Coinbase, r) //r = ((uncle.Number + 8) - header.Number) * blockReward /8

        r.Div(blockReward, big32) //r = blockReward/32
        reward.Add(reward, r) //每多一个uncle，打包者会在blockReward的基础上多一个blockReward/32
    }
    state.AddBalance(header.Coinbase, reward) //给挖矿者增加reward
}
