1. When a new block is found, PPLNS method will be applied to calculate the last N shares contributed by each user.
2. Here N = Difficulty / 2, so now it will be 944393.
3. SMPPS method will then be used to decide the value of each share.
4. The value of each share = 50 * 0.9 / 944393, which is 0.0000476.
5. The factor 0.9 in the above equation is designed to reduce the risk of negative pool buffer.
6. When the block is confirmed, pay out will be made using SMPPS. if block invalid, no action.
7. If (50+pool buffer)>=(all unpaid),then pay out all.(new pool buffer)=50+(previous pool buffer)-(all unpaid).
8. Otherwise, pay out ( unpaid for a user ) / ( all unpaid ) * ( 50 + pool buffer) , and (pool buffer) = 0
9. if the (pool buffer) > 300 BTC, bonus will be given. That is,
(a user's previous shares without bonus) / ( all previous shares without bonus ) * ( pool buffer - 200 ).
so the mixed payment system will give honest miners best values and very few risk!
you can be paid for several times for same share when lucky.
Our share price is higher than deepbit in fact if you know how it work.
the digger who find the first block will been given a 2 btc bonus.
