The contract here is a sublinear staking contract: if you are in the whitelist (specified as an ERC1155 collection), then you can stake N coins, and get a return of N ** 0.75 coins per slot, for as long as the contract has coins to pay for it. There is a fundedUntil mechanism that ensures that if the contract runs out of money, every staker gets rewarded for every slot up to the fundedUntil timestamp, and the mechanism doesn't turn into a fractional reserve. https://github.com/ethereum/research/blob/master/sublinear_staking/code.vy Bounty of total 2 ETH for identifying any bugs / vulnerabilities in the contract and proposing specific fixes, if multiple issues are found the bounty will be split based on severity. Amount: 2 ETH @bountybot
