UOS共识节点收益计算

UOS的共识节点，奖池有三个：uosio.bvpay、uosio.bpay 、uosio.vpay
他们之间的关系是，uosio.bvpay是奖池源头，uosio.bpay是出块奖池，uosio.vpay是投票奖池。

uosio.bvpay奖池源奖金的0.8将会进入出块奖池，奖池源的0.2将会进入投票奖池。
查看总奖池：

cluos --url http://rpc.uos.iccob.com:9008 get table uosio.bvpay uosio.bvpay bpvtpay
{
  "rows": [{
      "id": 0,
      "start_line": 1554185715,
      "laster_line": 1554340049,
      "dead_line": 1556777715,
      "inherit": "0.0000 UOS",
      "quantity": "244518.9665 UOS"
    },{
      "id": 1,
      "start_line": 1556777715,
      "laster_line": 1556777715,
      "dead_line": 1559369715,
      "inherit": "0.0000 UOS",
      "quantity": "0.0000 UOS"
    }
  ],
  "more": false
}

curl命令：

curl --request POST \
--url http://rpc.uos.iccob.com:9008/v1/chain/get_table_rows \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--data '{"code":"uosio.bvpay","table":"bpvtpay","scope":"uosio.bvpay","json": true}'

id = 0代表当前奖励周期，id = 1代表下一次奖励周期，周期长度为30天。
假如现在的时间戳在周期０内，那么bp发起一次领奖，能领取多少钱呢？
假设为领取时刻为ｔ,则奖池源发放的奖金为：

out_all = (t - laster_line_0) * quantity_0 * 10000 / (dead_line_0 - laster_line_0);  （１）

奖金会分为两部分流入uosio.bpay与uosio.vpay。其中，0.8*out_all 进入uosio.bpay,0.2进入uosio.vpay。

里面有4个参数与奖励有关

"pervote_bucket": 27244585　　－－－　当前投票奖励资金池
"perblock_bucket": 100966841　－－－　当前块奖励资金池
"total_unpaid_blocks": 183296　－－－　当前未结算的区块数
"total_producer_vote_weight": "28178000000.00000000000000000"　－－－　当前投票总量

下面查看bp的具体情况，以“uoskkkkonebp”为例:

cluos --url http://rpc.uos.iccob.com:9008 get table -l 1 -L uoskkkkonebp --index 1 uosio uosio producers
{
  "rows": [{
      "owner": "uoskkkkonebp",
      "total_votes": "1000000000.00000000000000000",
      "producer_key": "UOS8VjUQXSovjJ5LuubcAUK9r5LYda7j5dLTJcfrBHm6VSP2L3d8Y",
      "is_active": 1,
      "is_remove": 0,
      "release": 0,
      "url": "https://uoskkkkonebp.com/chain",
      "unpaid_blocks": 7577,
      "last_claim_time": "1554259259000000",
      "location": 0,
      "ulord_addr": "UWKPFY3dVd1z5zHancEFLy2XYpawbZWHNn"
    }
  ],
  "more": true
}

curl:

curl --request POST \
--url http://rpc.uos.iccob.com:9008/v1/chain/get_table_rows \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--data '{"code":"uosio","table":"producers","scope":"uosio","json": true , "index_position":"primary","limit":1 , "lower_bound":"uoskkkkonebp"}'

uoskkkkonebp的获得票数为1000000000.00000000000000000，未结算的生产区块数量为7385，最后一次领取奖励的时间戳为：1554259259000000

那么如果ｔ时刻(t > 1554259259000000 + 3600)
uoskkkkonebp能领取出块的奖励为m,则:

m =  (out_all*0.8 + perblock_bucket)*unpaid_blocks / total_unpaid_blocks   (2)

uoskkkkonebp能领取的投票奖励为n,则:

n= (out_all*0.2 + pervote_bucket)*total_votes / total_producer_vote_weight  (3)
注：当n >= 100 0000时，即投票奖励大于100UOS,n才有效,否则不会发放投票奖励

uoskkkkonebp能够领取的总奖励为：m+n ,由(1)、(2)、(3)式可算出，注意最后得到的单位是“分”，要转化为"元",需要除以10000.
总结：
从(1)式可以看出，总奖池放出量在一个周期内是均匀的，但是由于每个bp领取的时间点不同，每个人计算得到的奖励是不同的。
