1// Package bubblerumble5 is the fifth Bubble Rumble realm: v4's game whole, with
2// one new slice. Of every bid 50% goes to the pot, 30% is credited at once to the
3// pool's earlier bidders pro-rata to what they paid in, 10% to whoever invited the
4// bidder, 5% to the pool's creator — and 5% to the BUBBLE treasury: the token
5// realm's own sub-realm (bubbletreasury), which nothing moves but a decided vote
6// of the BUBBLE holders. The five percent comes out of the pot's share alone; the
7// dividends, the inviter's and the creator's slices are v4's. Seeds (a creator's
8// own money into a new pool) and shots pay no royalty: a seed is a gift to the
9// players, and a shot's losing side already feeds the pot. Every pool has a last
10// day, a flag war at the close, credited earnings and Withdraw, a clock that can
11// be bought down but never under MinClock, and the shot that can win the pot:
12//
13// - A shot is still extra money on a bid, a chance to pop the bubble at once.
14// The chance is 0.8 × shot / take, at most 1% a shot, where the take is what
15// a pop would pay the shooter right now: the pot less the team's 35%, times the
16// winner's live share (LiveBps). So the pot keeps a fifth of every shot's fair
17// value however far the last day has slid, and a hit pops the bubble: the pool
18// closes with the shooter as its winner and Claim pays it as any pop.
19// - The draw's randomness is a commit-reveal by the keeper — the operator's own
20// box, which also settles pools on time. The keeper publishes sha256 hashes of
21// secrets ahead of time (Commit); a bid with a shot takes the next unused one;
22// the shot is drawn when someone (the keeper, or anyone) reveals that secret
23// (Reveal) in the blocks ShotDelay to ShotDelay+ShotWindow after the bid. The
24// seed is the secret with the shot's own facts and the reveal block's height
25// and time. Nobody without the secret can grind it: not the shooter, not a
26// validator. The secret's holder knows the two candidate block times a block
27// ahead and may pick which of the window's three blocks to reveal in — three
28// rolls, at most 2.4× fair on a 1% shot — which is why the keeper key never
29// bids or shoots, and its operator never shoots. (The site's own keep-alive boops come from another key and
30// pay the royalty like any boop; for the operator, who votes the treasury,
31// that slice is a wash — said here so nobody has to work it out.)
32// - A shot not revealed in its window, or on a pool that closed first, is void:
33// it goes into the pot and counts as a miss, as in v3. Nothing is refunded, so
34// withholding a reveal never pays whoever withholds it. What remains is that a
35// keeper who leads a pot could withhold a stranger's hit and let the money fall
36// into the pot it leads: refused shots are counted on the pool for all to see,
37// and so are reveals that came in the window's later blocks (the honest keeper
38// always reveals at the first), so a keeper choosing its block would show.
39// - Shots are sold only while the keeper is alive: a shot needs a free commitment
40// and a sign of life (Commit or Heartbeat) within KeeperFresh. Otherwise the bid
41// stands and the shot's money goes straight back in the same transaction.
42// - Shots are refused in the last quarter of a pool's life (which also keeps every
43// reveal window clear of the last day) and under MinShot. RevealTip is taken
44// from every shot and credited to the keeper whoever sends the reveal (the
45// secret sits in the mempool, and a proposer could copy it), so the keeper
46// pays for itself. The keeper's own shots are refused outright.
47// - Reveals go in shot order, so among two pending shots nobody chooses which pops.
48//
49// Residuals, stated plainly: the secret holder's three rolls; the keeper-defender
50// veto above; a proposer who reads the keeper's reveal in the mempool holds the
51// secret too, and proposing the window's blocks could drop the reveal for a roll
52// it does not like or leave it out altogether (a void), which Late and Voided
53// show; keeper and validator together could grind. SetShots is the switch if any
54// of it is seen. SetKeeper drops every unused commitment.
