UOS的共識節(jié)點(diǎn)，獎(jiǎng)池有三個(gè)：uosio.bvpay、uosio.bpay 、uosio.vpay
他們之間的關(guān)系是，uosio.bvpay是獎(jiǎng)池源頭，uosio.bpay是出塊獎(jiǎng)池，uosio.vpay是投票獎(jiǎng)池。

id = 0代表當(dāng)前獎(jiǎng)勵(lì)周期，id = 1代表下一次獎(jiǎng)勵(lì)周期，周期長度為30天。
假如現(xiàn)在的時(shí)間戳在周期０內(nèi)，那么bp發(fā)起一次領(lǐng)獎(jiǎng)，能領(lǐng)取多少錢呢？
假設(shè)為領(lǐng)取時(shí)刻為ｔ,則獎(jiǎng)池源發(fā)放的獎(jiǎng)金為：

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

獎(jiǎng)金會(huì)分為兩部分流入uosio.bpay與uosio.vpay。其中，0.8*out_all 進(jìn)入uosio.bpay,0.2進(jìn)入uosio.vpay。

下面查看bp的具體情況，以“uoskkkkonebp”為例:

cluos --url http://rpc.uos.iccob.com:9008 get table -l 1 -L uoskkkkonebp --index 1 uosio uosio producers
{
  "rows": [{
      "owner": "uoskkkkonebp",

uoskkkkonebp的獲得票數(shù)為1000000000.00000000000000000，未結(jié)算的生產(chǎn)區(qū)塊數(shù)量為7385，最后一次領(lǐng)取獎(jiǎng)勵(lì)的時(shí)間戳為：1554259259000000

那么如果ｔ時(shí)刻(t > 1554259259000000 + 3600)
uoskkkkonebp能領(lǐng)取出塊的獎(jiǎng)勵(lì)為m,則:

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

uoskkkkonebp能領(lǐng)取的投票獎(jiǎng)勵(lì)為n,則:

n= (out_all*0.2 + pervote_bucket)*total_votes / total_producer_vote_weight  (3)
注：當(dāng)n >= 100 0000時(shí)，即投票獎(jiǎng)勵(lì)大于100UOS,n才有效,否則不會(huì)發(fā)放投票獎(jiǎng)勵(lì)

uoskkkkonebp能夠領(lǐng)取的總獎(jiǎng)勵(lì)為：m+n ,由(1)、(2)、(3)式可算出，注意最后得到的單位是“分”，要轉(zhuǎn)化為"元",需要除以10000.
總結(jié)：
從(1)式可以看出，總獎(jiǎng)池放出量在一個(gè)周期內(nèi)是均勻的，但是由于每個(gè)bp領(lǐng)取的時(shí)間點(diǎn)不同，每個(gè)人計(jì)算得到的獎(jiǎng)勵(lì)是不同的。
