PoolTogether PrizePool Upkeep

PoolTogether Operations contracts is PoolTogether's integration with ChainLinks upkeep system, currently in beta.

How it works

The goal of this system is to fully automate the awarding of the PoolTogether governance owned prize pools.

A registry of these prize pools exists (as an Ownable MappedSinglyLinkedList) and the prize strategy for each prize pool checked every block (canStartAward() and canCompleteAward()) to see if upkeep is required.

If upkeep is required then either startAward() or completeAward() are called on the prize pool.

To prevent out-of-gas situations, an owner updatable upkeepBatchSize is maintained to prevent attempting to award too many prize strategies in the same transaction.

An owner updatable upkeepMinimumBlockInterval is also maintained so as to mitigate multiple performUpkeep() transactions within the same block - if a transaction is to be included in the same block, it will revert.
