Say the pool shuts down tomorrow (not saying it will but bear with me.) What happens to all the miners who have a balance on their account? Obviously new blocks won't be mined so we can't be paid out the traditional way. Do you have enough BTC in cold storage to pay everyone off? Right now there's a staggering 571.77 BTC in the payout queue and that's not even counting the miners who haven't hit their minimum. Furthermore, how does the cold storage wallet get paid? Do you send off a percentage of each new block to it? Or is it only credited when the payout system goes into "fallback" mode?
This just confuses me because the point of the CPPSRB system is that there will never be more BTC in shares credited than what the pool actually mines. Yet it seems the "debt" in the payout queue continues to grow and we're at the mercy of the miners tomorrow to pay off what we mined yesterday.
First, to clarify, shelved shares are not "owed" to you. They represent work you did that the pool has not yet found money to pay for yet. By the CPPSRB rules, theses are "worth" nothing until the pool finds enough blocks, if it ever does.
However, rewarded-but-unpayed shares (your account balance that grows until you hit your treshold then you get payed) is indeed owed to you; and if the pool were to close down, it must have enough money on hand to pay for them for all their miners.
Right now, the cold storage address has 777.68 BTC, and the payout queue is 652.41 BTC long. So Eligius has more that enough money to cover the queue. The remaining 125.27 BTC would then cover those who were rewarded BTC but have not yet hit their treshold. (However, I do not know how to check it these amount equals, but it does seem a reasonable value.)
So, no need to worry.
The cold storage address is 18d3HV2bm94UyY4a9DrPfoZ17sXuiDQq2B. It is mainly funded in the following conditions:
- The pool is in failsafe mode.
- The total amount of BTC in the queue is less that a block's worth. (i.e., not enough miners are above their treshold)
- Two blocks are found so fast by Eligius that it had not enough time to properly compute who gets what amount.
In usual condition, the miners are payed directly from the generation transaction, so the queue length does not grow. (it will of course vary a little bit according to the different miner's threshold, but it averages out over a sufficient long time)
When one of the above condition is met, since miners were not payed by the block, the queue grows, and fast. But, that money will be sent, manually, some time later.
The cold storage address is also sent 0.00000001 BTC each time Eligius finds a block. It can be used to quickly check directly on the blockchain if Eligius has found a block even if the pool's webserver is down.
