Package bubblerumble is a last-bidder-wins game in GNOT.
A pool has a pot and a clock. Every bid goes into the pot and resets the clock; the Nth bid costs BasePrice·√N. When the clock runs out, the last bidder takes the whole pot. Anyone can open a pool, and the coins sent with CreatePool seed its pot.
Paying more than the price buys a shorter clock: k× the price gives that bid a clock of window/k, never below a tenth of the window. The whole amount goes into the pot, and the next bid runs the full window again.
Price of the next bid in a pool with the given base price and n bids so far. Sublinear in n: bid 1 costs base, bid 4 costs 2·base, bid 100 costs 10·base.
