1// Package bubblerumble4 is the fourth Bubble Rumble realm. v3's game stays whole:
2// of every bid 55% goes to the pot, 30% is credited at once to the pool's earlier
3// bidders pro-rata to what they paid in, 10% to whoever invited the bidder, 5% to
4// the pool's creator; every pool has a last day, a flag war at the close, credited
5// earnings and Withdraw, a clock that can be bought down but never under MinClock.
6// What v4 changes is the shot: it can now win the pot.
7//
8// - A shot is still extra money on a bid, a chance to pop the bubble at once.
9// The chance is 0.8 × shot / take, at most 1% a shot, where the take is what
10// a pop would pay the shooter right now: the pot less the team's 35%, times the
11// winner's live share (LiveBps). So the pot keeps a fifth of every shot's fair
12// value however far the last day has slid, and a hit pops the bubble: the pool
13// closes with the shooter as its winner and Claim pays it as any pop.
14// - The draw's randomness is a commit-reveal by the keeper — the operator's own
15// box, which also settles pools on time. The keeper publishes sha256 hashes of
16// secrets ahead of time (Commit); a bid with a shot takes the next unused one;
17// the shot is drawn when someone (the keeper, or anyone) reveals that secret
18// (Reveal) in the blocks ShotDelay to ShotDelay+ShotWindow after the bid. The
19// seed is the secret with the shot's own facts and the reveal block's height
20// and time. Nobody without the secret can grind it: not the shooter, not a
21// validator. The secret's holder knows the two candidate block times a block
22// ahead and may pick which of the window's three blocks to reveal in — three
23// rolls, at most 2.4× fair on a 1% shot — which is why the keeper key and its
24// operator never bid or shoot.
25// - A shot not revealed in its window, or on a pool that closed first, is void:
26// it goes into the pot and counts as a miss, as in v3. Nothing is refunded, so
27// withholding a reveal never pays whoever withholds it. What remains is that a
28// keeper who leads a pot could withhold a stranger's hit and let the money fall
29// into the pot it leads: refused shots are counted on the pool for all to see,
30// and so are reveals that came in the window's later blocks (the honest keeper
31// always reveals at the first), so a keeper choosing its block would show.
32// - Shots are sold only while the keeper is alive: a shot needs a free commitment
33// and a sign of life (Commit or Heartbeat) within KeeperFresh. Otherwise the bid
34// stands and the shot's money goes straight back in the same transaction.
35// - Shots are refused in the last quarter of a pool's life (which also keeps every
36// reveal window clear of the last day) and under MinShot. RevealTip is taken
37// from every shot and credited to the keeper whoever sends the reveal (the
38// secret sits in the mempool, and a proposer could copy it), so the keeper
39// pays for itself. The keeper's own shots are refused outright.
40// - Reveals go in shot order, so among two pending shots nobody chooses which pops.
41//
42// Residuals, stated plainly: the secret holder's three rolls; the keeper-defender
43// veto above; a proposer who reads the keeper's reveal in the mempool holds the
44// secret too, and proposing the window's blocks could drop the reveal for a roll
45// it does not like or leave it out altogether (a void), which Late and Voided
46// show; keeper and validator together could grind. SetShots is the switch if any
47// of it is seen. SetKeeper drops every unused commitment.
